• Question about the installation of 11g R2 and 10g R2

  Hi, my system is Windows 7, 32-bit with Service Pack 1.
  
  Can I install Oracle 10 g R2? Or Oracle 11g R2?
  
  Could someone send me the download links?
  
  Thank you very much.
  
  Happy Thanksgiving!

  Salvation;

  Several user forum already answered your question,

  Can I install Oracle 10 g R2? Or Oracle 11g R2?

  Both version can be installed on win 7. 10g to 10.2.0.5 version. For this version and also 10.2.0.1 reference, you must connect metalink and must raise SR or contact the local oracle office. Because as mentioned here only 11.2 download available

  If your Windows 7 is version home you can create vmmachine on your win7 OS that download oracle linux(OEL 5.x) of delivery site that install this on your vmmachine and can use it for your db instalation problem

  Could someone send me the download links?

  As mention before only 11g download available on OTN:
  http://www.Oracle.com/technetwork/database/Enterprise-Edition/downloads/index.html

  PS: Please don't forget to change the status thread answer whether it is possible when believe you your thread replied, he pretend to wasting time in other forums users while they are looking outstanding which is not answered, thank you for understanding

• Questions about LogMiner.

  Greetings. We use 11G and have installed OEM, but not DB Diagnostic Pack. I have a few questions about this utility:

  (1) can be used if the Pack diagnosis DB is not installed? I ask because I know that some of these utilities are not available if it is not.

  (2) I know that I need to enable logging extra to use it. Is there any show / General cool space that are associated with?

  (3) are there any air show with the help of LogMiner itself? In particular, I could see what happens if analyzes the current journal.

  (4) what the tool commonly used to determine what query performance caused problems for awhile?

  Thank you!

  1 Yes. It is not part of a pack.
  2 of course additional recording will result in repeat. The impact on performance is usually not noticeable.

  3 the result of mining is placed in the shared pool and queries on v$ logmnr_contents ask shared pool this may cause reduced performance.

  4 n ° do not forget that you are again mining. This means DML. Selects won't be in your recovery.

• A question about external authentication with PHP OCI8 using a portfolio store

  Hello
  

  SQL> SELECT * FROM v$version;
  
  BANNER
  --------------------------------------------------------------------------------
  Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
  PL/SQL Release 11.2.0.1.0 - Production
  CORE     11.2.0.1.0     Production
  TNS for Linux: Version 11.2.0.1.0 - Production
  NLSRTL Version 11.2.0.1.0 - Production
  
  SQL> 

  OS: Linux Fedora Core 17 (x86_64)
  PHP Version: 5.4.14
  Apache version (httpd): Apache/2.2.23 (Fedora) 

  I have a question about OCI8 connection to the Oracle server via portfolio, which I understand is a good practice because we do not have to hard code the users password. I'm trying to read pages 117 and 118 of the book The Underground PHP and Oracle manual online to learn how to set up a portfolio. I proceeded by steps as explained in these two pages (except that at the end I connect, as a normal user, not a privileged user) yet, apparently PHP does not detect the user.
  
  Here's what I write in my script
  

  $connection = 
                  oci_connect 
                      (
                          "training", 
                          "", 
                          "php_ora_usr", 
                          "AL32UTF8"
                      );

  the training is the name of the user that I use in my PHP scripts to connect to the oracle database and the password is mypassword (is not true, just for the purpose of this thread :)) the code above gives me the following error:)

  Warning: oci_connect(): ORA-01005: null password given; logon denied in /var/www/html/myscript.php on line 91
  
  Fatal error: Connection step: ORA-01005: null password given; logon denied in /var/www/html/myscript.php on line 13

  But if I also provide the password which is,

  $connection = 
                  oci_connect 
                      (
                          "training", 
                          "mypassword", 
                          "php_ora_usr", 
                          "AL32UTF8"
                      );

  Obviously it works, but at the same time, this means that my wallet is not operational.
  
  So I'll write here, step by step, how I did according to the instructions contained in the pages 117 and 118 of the above mentioned book and I would be grateful if you could kindly tell where I made the mistake (s)
  
  The following text was performed under my oracle linux (so the dbagroup)
  
  Step 01:_
  I created and provided the password for the directory of portfolio

  mkstore -wrl /home/oracle/wallet_dir -create

  Step 02:_
  I created an entry for my oracle user that will be used in my PHP scripts to connect to oracle
  user: training
  password: mypassword

  mkstore -wrl "/home/oracle/wallet_dir" -createCredential php_ora_usr training mypassword

  I also checked that the entry was actually created for my user in the portfolio

  $ mkstore -wrl "/home/oracle/wallet_dir" -listCredential
  Oracle Secret Store Tool : Version 11.2.0.1.0 - Production
  Copyright (c) 2004, 2009, Oracle and/or its affiliates. All rights reserved.
  
  Enter wallet password:                
     
  List credential (index: connect_string username)
  1: php_ora_usr training
  $ 

  Step 03:_
  I added the following to my $TNS_ADMIN/tnsnames.ora

  .  .  .
  php_ora_usr = 
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (CONNECT_DATA =
        (SERVER = DEDICATED)
        (SERVICE_NAME = db02)
      )
    )
  .  .  .

  Step 04_
  I added the following to my $TNS_ADMIN/sqlnet.ora

  # sqlnet.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/sqlnet.ora
  # Generated by Oracle configuration tools.
  
  NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
  
  ADR_BASE = /u01/app/oracle
  
  WALLET_LOCATION =
      (SOURCE =
          (METHOD = FILE)
          (METHOD_DATA =
              (DIRECTORY = /home/oracle/wallet_dir)
          )
      )
  SQLNET.WALLET_OVERRIDE = TRUE
  SSL_CLIENT_AUTHENTICATION = FALSE
  SSL_VERSION = 0

  _ Step 05
  The TNS_ADMIN environment variable is already set correctly in * / etc/sysconfig/httpd * so I didn't need to do something for this step
  
  
  Step 06_
  I gave to access Apache (as root) in the directory of portfolio (in fact, it seems that the user oracle (dba) of linux also has the required privileges to grant this access to the apache)

  # setfacl -m u:apache:rx /home/oracle/wallet_dir
  # setfacl -m u:apache:r /home/oracle/wallet_dir/{cwallet.sso,ewallet.p12}

  Step 07_
  Restart Apache

  # service httpd restart

  Step 08_
  Finally make a test connection using the connection string php_ora_usr which the entry was created earlier. And the test was not successful, as indicated above

  $connection = 
                  oci_connect 
                      (
                          "training", 
                          "", 
                          "php_ora_usr", 
                          "AL32UTF8"
                      );

  The error message:
  

  Warning: oci_connect(): ORA-01005: null password given; logon denied in /var/www/html/myscript.php on line 91
  
  Fatal error: Connection step: ORA-01005: null password given; logon denied in /var/www/html/myscript.php on line 13

  I would appreciate it if you could kindly shed some light.
  
  Thanks in advance,
  Dariyoosh

  That gives a good clue to begin with. With your platform/Apache/DB, you might need different ACLs. Test directory and permissions. Check what euid your Apache runs as. Good luck.

• EBS 12.1.3: a few questions about cloning

  Hello
  
  We have EBS 12.1.3 on AIX 7.1.
  
  A few questions about the cloning of level shared environment of application layer non-shared application environment. We followed 'Cloning Oracle Applications V12 with rapid Clone [ID 406982.1]'
  
  Environment (shared application layer) source:
  -Two nodes in the active application and LBS
  -A database of active and a passive database configuration with Oracle Data Guard.
  -Terminate SSL at the load balancer
  -Updated CFP implementation
  
  Environment target (level app not shared):
  -A single node of the application active
  -One data node active
  -Without SSL
  -No PCP
  
  After the cloning was completed, we noticed the following problems in the target system:
  
  (1) home page is not available because application $CONTEXT_FILE layer always contains the endpoint "https" and ssl settings.
  
  Workaround solution:
  
  Change (with text editor) layer Application $CONTEXT_FILE as follows.
  < webentryurlprotocol oa_var = "s_webentryurlprotocol" custom = "yes" > http < / webentryurlprotocol >
  < sslterminator oa_var = "s_enable_sslterminator" > # < / sslterminator >
  < login_page = "s_login_page" custom = 'yes' oa_var > http://myhost.mydomain.com:8000/OA_HTML/AppsLogin < / login_page >
  < externURL oa_var = "s_external_url" custom = "yes" > http://myhost.mydomain.com:8000 < / externURL >
  
  Run the automatic configuration service and application layer.
  
  Is there a better solution and supported for this?
  
  (2) simultaneous managers do not work properly, because they still have old names of node (used in the CFP in the source system). The solution is used:
  
  1. connect to the EBS GUI web and delete all nodes of all concurrent managers.
  2 shutdown application layer. Check that all concurrent managers have been extinguished. If not, kill the process manually
  3. as a user apps run cmclean.sql
  4 restart the application layer
  
  Is there a better solution for this?
  
  (3) database ARCHIVELOG mode nonarchivelog mode changes in the target system. Is anyway to prevent this?
  
  (4) in addition, we would like to make a full clone (app + db levels) of production without closing the application. Is this possible? What would be the best documents to describe it? In Production, we have Oracle Data Guard physical standby installation as per "Note technique Oracle: Business Continuity for Oracle E-Business release 12 Using Oracle 11g Physical Standby Database [1070033.1 ID]. This can be used when executing a clone of warm for the database, right? What application layer? The steps in 406982.1 include AutoConfig in what application level should be running down. Must the application be broken when running "to maintain the Snapshot information?"
  
  (5) one last question (not related to cloning). Oracle Enterprise Manager console webUI has recently stopped working in IE8. For example, https://myhost.mydomain.com:5501 / em gives "cannot display the Page. It was working properly last week. In Firefox, the same link works fine. Any ideas how to solve this problem?
  
  Thanks for your replies in advance.
  
  BR,
  TH

  (1) home page is not available because application $CONTEXT_FILE layer always contains the endpoint "https" and ssl settings.

  Workaround solution:

  Change (with text editor) layer Application $CONTEXT_FILE as follows.
  http
  #
  http://myhost.mydomain.com:8000/OA_HTML/AppsLogin
  http://myhost.mydomain.com:8000

  Run the automatic configuration service and application layer.

  Is there a better solution and supported for this?

  No, you must modify the context manually and run the automatic configuration.

  (2) simultaneous managers do not work properly, because they still have old names of node (used in the CFP in the source system). The solution is used:

  1. connect to the EBS GUI web and delete all nodes of all concurrent managers.
  2 shutdown application layer. Check that all concurrent managers have been extinguished. If not, kill the process manually
  3. as a user apps run cmclean.sql
  4 restart the application layer

  Is there a better solution for this?

  You follow the best approach. You could update the details of the server node if you wish.

  (3) database ARCHIVELOG mode nonarchivelog mode changes in the target system. Is anyway to prevent this?

  By default, the quick Clone will create the target in noarchivelog mode database.

  (4) in addition, we would like to make a full clone (app + db levels) of production without closing the application. Is this possible? What would be the best documents to describe it? In Production, we have Oracle Data Guard physical standby installation as per "Note technique Oracle: Business Continuity for Oracle E-Business release 12 Using Oracle 11g Physical Standby Database [1070033.1 ID]. This can be used when executing a clone of warm for the database, right?

  Fix.

  What application layer? The steps in 406982.1 include AutoConfig in what application level should be running down. Must the application be broken when running "to maintain the Snapshot information?"

  You can copy the files from the application tier node, while demand is rising. And, there is no need to stop the application to run "to maintain the Snapshot information."

  (5) one last question (not related to cloning). Oracle Enterprise Manager console webUI has recently stopped working in IE8. For example, https://myhost.mydomain.com:5501 / em gives "cannot display the Page. It was working properly last week. In Firefox, the same link works fine. Any ideas how to solve this problem?

  If it works from a browser, then it should not be a problem of EM. Have you tried another client and see if it works? Have you changed a setting in your Internet Explorer browser? Please make sure you add the URL of the EM to the list of trusted sites.

  Thank you

• SPFile in ASM

  Hello
  
  In oracle 11g r2 asm where spfile is going to be located.
  by connecting the asm instance I quried
  
  SQL > show parameter spfile;
  
  He gave
  
  SPFile = +DATA/asm/asmparameterfile/registry.253.773257797
  
  
  the file must create spfile + ASM.ora right. ? So what is the registry.253.773257797 file.
  
  where can I find exactly spfile
  
  Thank you!

  With 11.2, asm spfile does not behave like an ordinary spfile.
  The file you mentioned is your true spfile. If you want to see it or change it using the following commands to asmcmd:
  spget - to locate the spfile
  spmove - move the spfile

  There are other commands related to asm spfile, you can check using asmcmd

• Questions about Failver customer and rapid failover

  have some questions about customer and quick Faiolver of Oracle Database HA failover. Before asking these questions, I want to explain my environment. Here are the details.
  
  
  
  -We have two physical locations called "ABC" and "PQR".
  -ABC is the main site.
  -PQR is the backup site.
  -In ABC, we have the database to Oracle RAC (11.2.0.2) with two nodes.
  -In the PQR, we have only one stand-alone server (11.2.0.2) database with ASM. This isn't a RAC.
  -Data Guard has been configured between ABC and PQR and it works as expected.
  -Please note that we have a license for Active Data Guard.
  -We have products of Oracle Identity Management to ABC and PQR and they will use the RAC database as a primary database that is in the CBA.
  -We have not yet set up a Data Guard Broker.
  
  We want to achieve under objectives:
  
  
  Objective 1:
  -------
  
  Whenever primary CARS down completely, standby database becomes a primary database AUTOMATICALLY and it should allow the read/write operation.
  I guess it's called 'Fast Failover'. Please let me know if I'm wrong.
  
  Issues related to the:
  
  -To do this, I need to set up Data Guard Broker so that this standy database becomes primary when CARS go down completely with a power outage, planned or not.
  -Let's say that CARS falls does completely, how long take Data Guard Broker do standby db as primary.
  -What the client application / which is already connected to the CARS.
  -Let's DB standby became as primary and after some time if RAC comes back, keep data automatically becomes the primary role of RAC?
  
  
  Objective 2:
  --------
  
  As I explained above, all products Oracle IDM and applications to speak to the RAC database, what do know only on the RAC database, which is the main. They are not aware of the pending database.
  
  -Whenever a client session is underway with the primary database of CARS if CARS completely falls down, we would like to wait until the client session should get transferred datbase standby without losing session information. However before that happens, standby database should become primary because the client session can perform write operations.
  
  -Whenever a client attempts to connect to the primary CARS and assumes that the cab is completely down, we would like to expect from any client connections should are transferred pending database.
  However before that happens, standby database should become primary because the client session can perform write operations.
  
  According to my knowledge, above scenarios are called "client failver." Please let me know if I'm wrong.
  
  
  
  Issues related to the:
  ----------
  
  1. Please throw some light to reach above features.
  2. According to my understanding, before customer failover happens, fast failover expected has already occurred and ensure should get the switch for the main role. I guess that all this happens thanks to timeout settings. What are those.
  
  
  Could you please help?
  
  Thank you

  I didn't say that clients cannot reconnect automatically when primary fails: I meant that client sessions can generally reconnect and also keep any session state.

  Yes, they can reconnect but only to keep the session state for a SELECT statement. It is also possible with Data Guard, not only in the CARS I wrote: here's a demo with 10 g
  http://uhesse.WordPress.com/2009/08/19/connect-time-failover-transparent-application-failover-for-Data-Guard/.
  What is not possible is to maintain a session state: (INSERT/UPDATE/DELETE) pending transactions must be cancelled.

• Question about *.aud in audit_file_dest fields

  A node 3 RAC 11 g 2 on Linux 5.2, we recently had a full disk because of too many files in audit_file_dest. The parameter audit database is such

  SQL> show parameter audit
  
  NAME                                 TYPE        VALUE
  ------------------------------------ ----------- ------------------------------
  audit_file_dest                      string      /u01/app/oracle/admin/prdcch/adump
  audit_sys_operations                 boolean     FALSE
  audit_syslog_level                   string
  audit_trail                          string      DB

  With audit_sys_operations = FALSE, I don't expect operating SYS written to audit_file_dest. But in fact we still see a lot. Here are my questions about sys audit
  (1) how really turn off sys audit
  (2) I see much usefule sys files in audit_file_dest of the audit. A typical such file contained as (removded header)

  Sat Jul  2 19:15:22 2011 -05:00
  LENGTH : '155'
  ACTION :[7] 'CONNECT'
  DATABASE USER:[1] '/'
  PRIVILEGE :[6] 'SYSDBA'
  CLIENT USER:[6] 'oracle'
  CLIENT TERMINAL:[0] ''
  STATUS:[1] '0'
  DBID:[10] '2362038599'

  From what I understand, it tells me the time and duration of the session SYS. It don't me didn't say where machine (which can help to identify who connected in a SYS), not the activities

   I find this info is useless. I must missed something important, hope some one can shine some light here.
  3) If cannot stop the SYS audit, I would like to redrect the audit_file_dest to a differnt drive with larger space. Is there anything thing need special attention when doing it in RAC. Can each instance has differnt audit_file_dest?
  
  Thanks                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        

  Although audit_sys_operations is false, some actions are audited by default in 11g. See also DBA_AUDIT_TRAIL.
  (1) you can't turn it off
  (2) TERMINAL CLIENT is empty, it means that the connection of the server itself. In your example someone logged on locally as "/ as sysdba".
  (3) audit_file_dest is instance specific. You can put each in their own directory or put them all in a share. If the files are very small, according to the activity of DB there could be millions of them. In my environment remove us periodically as they age (more than 3 months).

• A few questions about integration between POET and EBS

  Hi you
  I am a new bie BIEE. In those days, have a look at the POET architecture and BIEE components. In the next project, there is some work on the development of POET based on request of the EBS. I have a few questions about integration:
  
  (1) generally, the POET application and database server is decentralized with application and database EBS? Both BIEE 10g and 11g version can be integrated with EBS R12?
  
  (2) in the POET administration tool, the first step is to create arrays of physics. If the source application is EBS, is it still necessary to create the physical tables?
  
  (3) if the physical creation of tables is needed, how to transfer data from the source of BSE BIEE physical tables tables? What ETL tool is preferred for most of developers? generator for warehouse or Oracle data integration?
  
  (4) during the data transfer phase, there are many many large data to transfer, how to keep the entire? for example, it must transfer 1 million lines of source to physical tables BIEE database, when 50% is completed, users try to open the POET report, they can see the new data of 50% on the reports? is there some transaction in phase control ETL?
  
  could someone give some pointers for me? I am very appreciated if you can also provide any other information.
  
  Thanks in advance.

  (1) generally, the POET application and database server is decentralized with application and database EBS? Both BIEE 10g and 11g version can be integrated with EBS R12?

  You shud look at OBI request here that uses OBIEE as a tool for reporting with pre-built modules. 10g & 11g comes with different versions of the applications of BI that supports sources such as Siebel CRM, EBS, Peoplesoft, JD Edwards, etc...

  (2) in the POET administration tool, the first step is to create arrays of physics. If the source application is EBS, is it still necessary to create the physical tables?

  His independent of any source. It comes to OBIEE modeling to create the RPD with all the layers. If you build from scratch, then you will need to create all layers else if BI Apps is used so you can get pre-built RPD and other pre-designed components.

  (3) if the physical creation of tables is needed, how to transfer data from the source of BSE BIEE physical tables tables? What ETL tool is preferred for most of developers? generator for warehouse or Oracle data integration?

  BI apps comes with ETL pre-built mapping to use with the tools majorly with Informatica. Only applications BI 7.9.5.2 comes with ODI, but oracle has the intention of having only ODI for any other versions.

  (4) during the data transfer phase, there are many many large data to transfer, how to keep the entire? for example, it must transfer 1 million lines of source to physical tables BIEE database, when 50% is completed, users try to open the POET report, they can see the new data of 50% on the reports? is there some transaction in phase control ETL?

  User will see still old data because its good enable Cache and serving it after each load.

• Questions about MRI

  Hi all
  
  My client asked me a few questions about MRI with ecm11g, I can't find the doc online answers, could someone tell me the answer?
  1. what kind of documents can be sealed by MRI, ms office should be able to be sealed, anyway, when I right click on a file .cmd or .rar in windows Resource Manager, there is no seal on in the option list
  2. is there a way to map IRM rights with model of account group/ECM ACL / security?
  3. text search full ECM can a doc sealed (for example: a word sealed) which is stored in ecm?
  
  Best regards

  I don't think that there is no configuration necessary.

  Just checked in 10g (Complutense University of MADRID and MRI):
  -There is a component called IRMIntegration
  -in the section of the Administration there is a menu item that allows configuration of base between the AAU and MRI (URL, port, etc) and it also contains an indicator "Index sealed Documents" - I think that it is the little thing that does not work in your system
  -When an element is integrated, it can be assigned to a metadata field called Protection MRI, which is filled with all the contexts in which a current 'seal' user allowed to (I assume that you do not see this area in your system)

  A context to this field of filling causes an item to be sealed. My system is a little slow, so I knew when the item was GENWWW, it was even made public. Once this was done, it was already sealed (and so was his web viewable format - spdf).

  I'll also take a look if the component is available in the 11g environment.

  As I expected: the component is not available in the 11g environment

• confusion about required_mirror_free_mb in asm

  Hello!
  
  I have confusion about required_mirror_free_mb in asm.
  
  I have 6 drives with normal redundancy and 4 failgroups.

  Here's my question, that how asm desides REQUIRED_MIRROR_FREE_MB i.e above case of 4 GB of...
  Please can someone answer me...

  Hi Muhammad,

  PLS, forget what I wrote before. Which is incorrect.

  Here's the explanation: If you look at the notes 798458.1 Incorrect calculation of Usable_file_mb and the documentation, you will find the following:

  "REQUIRED_MIRROR_FREE_MB indicates the amount of space that must be available in a disk group to restore full redundancy after worse failure that can be tolerated by the disk group."

  Unfortunately, the worst case in your 2 scenarios are defferent (many different):

  If you have 6 disks in 3 FGs is the worst failure
  -failure of a whole failgroup (ca. 1.420 + 1,420 GB) +.
  -failure of a disk in one of the 2 survivors starts (another approx. 1.2 GB, what is the result after the DG survining re-mirroring - you can see who is 1127 which corresponds to the number after you deletet a FG).

  In your other case, where you have only 4 discs 2 FG then the worst failure (to always maintain normal redundancy) is the failure of 1 drive:
  -Failure of a disk with data containing a maximum of 2047 (since it is the size of the disk).

  Hope he says.

• A question about the license of Oracle 1 g R2 Enterprise Edition

  Hi all
  
  
  I have a question about Oracle license and I would be grateful if you could help me thanks.
  
  I installed an Oracle (11g R2 Enterprise edition) server on a virtual linux machine. The pc being used for this purpose
  is my cell phone company (so a professional and not a personal computer). However, I use this Oracle Server
  only for the purpose, i.e. learning only to run the examples in my Oracle Press books (SQL, PL/SQL and some)
  administrative tasks) just to learn things.
  
  There is absolutely no data related to my business, stored or used on this server. Whenever I want to work with my
  data of the company, I use the Oracle server of the company that has the appropriate license of course. So, as I said, I
  Use this server of the company on the virtual machine only to run applications/programs in my Oracle Press books just for
  learning and I'm the only person who uses this server (no remote for other users).
  
  The reason why I needed to install this server on my PC, is that our DBA could not provide a training environment
  for me, with all the privileges and features.
  
  
  Should I buy a license for this Enterprise Server installed on my virtual machine?
  
  
  Thanks in advance,
  Dariyoosh

• Where can I ask a handful of general order questions about Firefox OS as a consumer and get the answers? (a forum or something similar)

  I have about seven questions about Firefox OS. I'm potentially interested in opting for a tablet that works instead of Android or iOS. I couldn't find a place to ask questions like that. Thank you!

• Where and how do I ask questions about Email?

  The Commission opening thingy is complicated, I have trouble finding my way around it.  I don't know where or how questions about email.  Is there an easier way than trawling through all these icons?  Like a list or something - as you get on all other forums on the internet?

  It would be a good starting point: Mac mini

  Or the appropriate under MAC Os and system software section.
