• Some doubts about the topology, interfaces and security modules

  Hello
  
  Below, some questions about the ODI:
  
  
  1. to use an LKM ODI always ask to use two different DATASERVERS (one for the SOURCE) and another to the TARGET?
  
  2. what would be the best way to create a new IKM with GROUP BY clauses?
  
  3. What is the required minimum PROFILE for developers users could import projects created in other ODI environments?
  
  4. If a particular WORK_REP is lost, it is possible that retrieve projects from version control information stored in the MASTER_REP?

  1.) Yes. LKM always loads data from one root to another.
  More than once I saw that even if there is a single physical server, several servers are configured in the topology Manager. This would lead to the use of a LKM because ODI consider 2 different servers.
  If the physical server is set only once, LKM won't be necessary.

  2.) IKM automatically adds a GROUP BY clause if it detects an aggregation function in the Interface implementation.

  3.) try to use the profile of the creator of NG.

  4.) this is not an easy task. But all the versioned objects are compressed and stored in a BLOB field in the master repository.
  You will need to know the names and versions you need to recover.
  SNP_VERSION and SNP_DATA have this information. Retrieves the field BLOB SNP_DATA and unpack using a zip utility. This will give you the XML property of the object that was transferred.
  Now, you can import this xml file and retrieve the object.

  You will need to loop through all the records in order of I_DATA, then extract to .xml file, and then import them to build the work rep.

• Some doubts about 11g R2 Policy Based/Scan

  Hello
  
  I went through several documents, including the help of Oracle to understand oracle new feature Policy Based management/Scan, I also explored a few RACSIG Webinar by Markus which were useful, but still not able to understand the concept. I will be grateful if someone can help me understand the concept if you please.
  
  Written document - the advantage of the creation of a pool of servers (policy) is to manage the workload automatically. I do not understand how it will manage the workload automatically. I understand according to importance and setting min/max, the servers will allocate/deallocate pools as a result.
  
  For example - is a server pool: high_priority pool with min 2 servers. first and foremost, he is serving 2 instance of database on payroll
  another pool of servers: low_priority pool with min 2 servers with low priority, he is serving 2 HR database instance
  
  In this case, any expelled obtained high_priority server, it should take only one low_priority server. (That's what expression I so far after going through the documentation. Please correction if I'm mistaken).
  
  1st question: doest which means that he's going to stop a case of HR running on low_priority pool and will allocate for this server at high_priority
  and as a result instance payroll goes up.
  
  2nd question: can still reach TAF feature using server pools. That is, I read that I can have a uniform service that runs on all instances
  (I guess that means favorite)... or the service can run on any single server (singletone)
  
  
  question 3: feature with SCAN, where we put remote_listener = SCAN_LISTENER, and clients will connect first to the SCAN and then had diversion to local listener.
  What is the advantage to have VIP for each node. SCAN listener knows which instance is in place, which is the less loaded can connections directly to the front
  local listener. (we can start using public ip for listener)
  
  my doubt is: 10 g, we only used vip to get quick notification or avoid tcp timeout... and then we got to redirect to some other listener/node to connect
  now SCAN can do the same features...
  
  Thank you in advance, I thank your time.
  
  Kind regards

  Hello

  In this case, any expelled obtained high_priority server, it should take only one low_priority server. (That's what expression I so far after going through the documentation. Please correction if I'm mistaken).

  Yes, that is the correct hypothesis.

  1.) Yes. The instance of database that HR will be stopped and a third instance of payroll will start.
  2 TAF.) will work for uniform and singleton services. However if you don't have 1 server in the serverpool (or have a singleton service) that there is no sense to work with preconnect.
  Note: TAF time varies based on uniform/singleton service and needs if service failover will need time so that it starts an instance. If you must configure TAF for such services with new higher attempts.
  (3.) the SCAN will redirect the customer to use the VIP for the final sign in the local listener. If it would use the public IP address and the server fails in exactly this moment, the client would wait for the TCP/IP timeout (which may take some time).
  With the VIP, he will tell him immediately, report that its connect has been unsuccessful and rerun the ANALYSIS to get a new connection.

  While the SCAN done the same thing in case of a change of itinerary as the VIP there 2 advantages:
  a.) no matter what your cluster, you must always 3 SCANs.
  (b) and they stay the same, no matter if the cluster has changed. (The VIPs are).

• Some doubts about the navigation in unifying

  Hi all

  I had a few questions about unifying navigation.

  Is it possible to move the admin mode user mode access level?

  I mean, if a particular feature as Manager of the shell I can only access from admin mode is it possible to provide access even in user mode?

  If so, how?

  My 2nd question of doubt is, currently, we can access company BPs level "Journal of society" or "Resource Manager" under shell 'Company Workspace'.

  Is it possible to move the "journal of the society" or "Resource Manager" in the folder? If yes how?

  I tried in "navigation user mode" to move the company BPs level at shell of the House, but I can't do it.

  To answer your questions:

  (1) User-Mode browser can have the user feature included. You cannot change the view mode Admin or move functions admin for user mode.

  (2) you cannot move these on the Home tab.

• Doubts about event handlers

  Hello
  
  I had some doubts about the event handlers in the IOM 11.1.1.5...
  
  (1) I want to use the same event handler for the message insert and update Post task... Can I use the same handler for this... If Yes, then how can I make...
  
  (2) can I create the single class of Plugin.xml and add all the jar files in IE single lib folder and zip them all together... If yes then what changes I need to do? Need only add that the plugin tags for different class in the plugin.xml file files? OR need to do something extra too...?
  
  (3) if I need to change something in any class handler... Is it need to unregister the plugin and register again...?
  If Yes... Is it need to delete the event handler using the weblogicDeleteMetadata command?
  
  (4) that we import the event handler of the path as event manager/db /... If we add all the evetn handler.xml files in this folder... As when importing weblogicImportMetadata called recursively all files in this folder... Now, if I need to change anything in one of the event handler class... so if import us from the same event manager/db folder... What to do... Create the copy of the eventhandlers? OR should I not add Eventhandler.xml files to class files, I made the changes...
  
  (5) given that I need to create emails on the creation of the user while recon and identification of email updated as a first name or surname updates... I had to use in the event handler.xml (entity-type = 'User' operation = "CRΘER") or something else...
  
  
  Help me clarify my doubts...

  Yes, on the update post you need to be check first if the first and last name change to update the mail electronic id, rather then calculation always email identification. So, you can check the path name are updated through the previous code.

• Oracle DBA will never offer 2nd chance for certification tests?

  Oracle DBA will never offer 2nd chance for certification tests?

  This time Oracle Sun java offers a 2nd chance for testing certification.

  So if you miss the 1st try, you get another free trial.

  Thank you Roger

  Think about that provide you a URL so that people can read the fine print.  Also certification of high-end Java identifythe which he made, and does not apply.

  Like any seller Oracle can offer carrots if she feels she will lead directly or indirectly, profits increased.  My guess is that they probably won't this offer on DBA tests... remember the historical lineage of exams have been through Sun Java...

• Oracle DBA study material

  I am preparing for certification Oracle DBA so wanted to find out what equipment is right for reference.

  I checked the Documentation but it seems complete database Oracle and I'm confused what order should I follow to get the Documentation.

  I know oracle databases SQL and LSPQ and now wanted to do an Oracle Certified Professional. I have the syllabus for OCP, but is it enough to be an expert like you.

  I saw many Post of oracle in this recreational but after reading your posts, I'm really confused if I am following correct path.

  You're experts so wanted to be an expert like you.

  Please guide me a good way.

  Thanks in advance.

  You are not an expert just by reading a few books. You must have a hands on experience too.

  Man learns by experience.

  Go to Oracle University courses as your will be learning database to Oracle University.

  If you want some free stuff then see under oracle database Documentation booklets.

• Doubts about licenses

  Hi all
  
  I have a few doubts about the price of licenses.
  
  I understand, I can deploy an APEX Server 11g XE free of charge, but what happens, if I want to install, a version no XE?
  
  Imagine a billing application, for 10 users, and I will assume that a Standard is sufficient. With the help of [this price list | http://www.oracle.com/us/corporate/pricing/technology-price-list-070617.pdf], how much exactly will cost?
  
  I understand I can get a license by user or server, or I have to license user and server too?
  
  Kind regards.

  Hello
  metric license is named plu user or license CPU (see the table of the core).

  for a quote, you can take a look in the oracle store or ask your dealer for an exact price oracle.

• Doubt about appsutil.zip in R12

  Hi all
  I have doubts about the application of rapid Clone on 12.1.3.I the latest patches have applied the fix using adpatch. After that, it must synchronize directories appsutil
  in RDBMS oracle home. I created appsutil.zip in the application layer and copied in the RDBMS oracle home. If I move the old appsutil to appsutil.old and extract appsutil.zip, the new appsutil directory should not constituted by the context file (I think). So, I have to run the automatic configuration based on the old cotextfile. Below, I have summarized the steps that I follow. Please check and correct me if I'm wrong.
  
  Copy appsutil.zip to $INST_TOP/admin/out of RDBMS oracle home
  CP $CONTEXT_FILE /tmp/mytest_vis.xml
  MV appsutil appsutil.orig
  unzip appsutil.zip
  Run autoconfig based on/tmp/mytest_vis.xml.
  
  
  Thank you
  Jay

  Jay,

  Is there a reason why do not use the old file context? What is the difference between the context file that will be generated by adbldxml.pl and the old file context?

  If there are updates in the application, it will be updated in the new xml file generated by adbldxml.sh, but he's not in the old file.

  So it is always best to run adbldxml.sh and autoconfig.

• Which is better foreign language must learn an Oracle DBA?

  Hello
  
  I intend to learn a foreign language (for example: Chinese, Japanese, french, Spanish, German etc,) this year. I am an Oracle DBA. Looking for some suggestions on the language in which I should choose.
  
  Thank you
  Delphine

  If the goal is to make it potentially easier to communicate with colleagues, whose native language is not English, I'd think Hindi or Mandarin would be the choice (even if you'd probably high enough to clear before your Hindi bar was better than English your colleague). If the goal is potentially do it yourself employable in other countries, as others have suggested, it would be important to look at which countries you are interested in - Spanish, French or German are likely to be relatively common in different parts of the world.

• Doubts about RAC infrastructure with a disk array

  Hello everyone,
  
  I am writing because we have a doubt about the correct infrastructure to implement RAC.
  
  Please, let me first explain the current design we use for storage Oracle DB. Currently, we are conducting multiple instances in multiple servers, all connected to a SAN disk storage array. As we know that it is a single point of failure so we have redundant controlfiles, archiveds and Orde in the table and in the internal drive of each server, in which case table has completely failed us 'just' need to recover cold backup nightly, applied hoops and Oder and everything is ok. This is possible because we have autonomous bodies and we can assume that this downtime of 1 hour.
  
  Now, we want to use these servers and implementing this table to a RAC solution and we know that this table is our only point of failure and wonder if it is possible to have a RAC multi-user solution (not AS a node) with controlfiles/archs/oder redundant internal drives. Is it possible to have each written full node RAC controlfiles/archs/oder in drives internal and applies these files systematically when the ASM filesystem used for CARS is restorations (i.e. with a softlink in an internal drive and using a single node)? Maybe the recommended solution is to have a second table to avoid this single point of failure?
  
  Thank you very much!

  Fix. It is the right solution.

  In this case, you can also decide to simply use the distribution on both tables and mirror of the array1 array2 on table data using the ASM redundancy options.

  Keep in mind that the redundancy is also necessary for connectivity. If you need at least 2 switches to connect on two tables and two HBA ports on each server, 2 fibers running, one to each switch. You will need driver multichannel s/w on the server to deal with the multiple I/O paths for storing same lun.

  Similarly, you will need to repeat this step for your Interconnect. 2 private switches, 2 cards on each server which are pasted. Connect then these 2 network cards on the 2 switches, one NETWORK card per switch.

  Also, don't forget to spare parts. Spare switches (one for the storage and interconnection). Spare cables - fiber and everything that is used for the interconnection.

  Bottom line - not a cheap to have a redundancy solution. What we can do is to combine the layer of Protocol/connection of storage with the interconnection layer and run both on the same architecture. Oracle database machine and Exadata storage to servers. You can run your storage Protocol (e.g. PRSS) and your Protocol (TCP or RDS) interconnection on the same 40 GB Infiniband infrastructure.

  As well as 2 switches Infiniband are needed for redundancy, plus 1 spare. With each server running a dual port HCA and one cable for each of these 2 switches.

• Doubt about tablespace temp

  Hi all
  
  DB version: 9.2.0.4.1
  version of the operating system: windows 2003 server sp2 (64-bit)
  
  the application team runs a job of loading each month which requires more temp tablespace.
  so every time my colleague will create new tablespace temp with 30 GB in size and makes it as default.
  He will be too old (old temp is also 30 GB).
  
  (1) if we do not create a new, old temp will be reused?
  (2) is it a bug in this version so that temp is not re-used? (unfortunately, my colleague don't know the answers for these)
  
  also, according to my understanding, oracle will not release tablespace temp paques1861 once the work is completed. Instead it is attributed to another transaction when required.
  Please correct if I am wrong.
  
  Thanks in advance.

  Glance,

  It's pretty simple: just as it is easy to become addicted to alcohol and hard to get rid of him, it is easy to increase a tablespace and hard to reduce its size.
  When you have
  -SQL with the runaway temporary use
  AND
  -you are convinced Oracle must release tablespace temp (which it doesn't)
  you use measures like your colleague has set up.

  Apart from wasting your time (you'd better give that SQL), you do nothing.

  Oracle does not release space for some reason:
  outside the allocation and release of the extents over and over again are very expensive.
  You want to avoid that.

• The daily tasks such as production Oracle DBA & developer DBA

  Hi all DBA,.
  
  I'm curious to know what you do every day as production Oracle DBA or developer DBA. More than a year ago, I became a DBA and before that, I was PL/SQL Developer. I navigate in the Administrator's guide and, now, in the middle of the Oracle database concepts. Then I intend to read backup and restore. As my day job: I check the backup log file. Check db objects and make sure that all are valid and check free space on each tablespace and adding data files if necessary. Also monitor top sqls session or above through OEM and tried tune sqls top of the page. Meet the demands of users, such 'kill a suspended session' and synchronize the data of a table between databases and refresh QA production db app. sometimes the air in the alerts log too if we have problems. Some people suggested TKPROF each file in short why trace the trace file generated. Don't you think that it is really beneficial? What should I do to improve the skills and abilities as an Oracle DBA. Really appreciate your ideas.
