• question about indexing settings

  Hello
  
  I was looking through the release of Essbase and here's my question about the index file I deleted a populous cube and I see everthing reset to 0 except index Cache current value that remained the same when the cube is populated.
  
  Any help or a response in this regard is greately appericiated.
  
  Thank you

  No, it should not change to zero. As I said, the key cache takes the memory when the application starts and keeps it until the application is stopped even if there are no data in the cube. HE maintains that the memory for when there no are data. I've seen of many inplementations where the client has set the cache to be really fat git thought would only use what it takes, but instead, the amout set gets consumed. So, I'm called asking how they can possibly be out of memory on their server. Moral of the story, do no bigger that it must really be or you will expect a lot of the key cache memory

• A Question about debugging...

  Hi all

  I have a question about debugging - specific probes. Is it possible to link and save the values on a wire (with a probe) which is a loop for the loop counter (or even a secondary value)?

  When I'm debugging code to a state machine that I often more easy to wire to the top of the State and the value, I am interested in a cluster, and then use 'generation antenna' and a registry change to add this element to each loop. I could also do this by indexing just out of the loop too.

  Once execution completes etc that I can look at the table (either using an indicator or a problem) to see what has happened to the value to each State/loop. And often, I know exactly where my code was wrong.

  My question is: is there a way to do this using regular probes without having to build an array? So, for example, I probe a digital wire and get a table of responses rather than just the last value on the wire?

  Thank you

  Dave

  I found this nugget that does exactly what I want - it's a custom probe developed by Darren.

  This post on the Exchange of ideas gives to think it should be at least provided with the package LV either integrated in the dev environment. Well worth voting for!

• Question about ActionBar on the first screen of the application

  Hi, I have a question about the actionbar behavior in the first screen of the application

  index.htm pushes immediately main.htm with actionbar. ActionBar clicks and responds correctly until I have add overflow on some buttons.

  When I click on the button of overflow, the overflow is displayed at the bottom of the page, the top of the overflow is put in correspondence with the upper part of the actionbar so buttons actionbar overflowing content is not visible.

  I reproduce this problem with the sample application.

  This is expected behavior? Is there a way around it?

• 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.

  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.

• Question about RAM CL

  Hi guys. I'm finalizing my PC build and I have a question about ram CL I can't find answers for hackers page here. http://ppbm7.com/index.php/news/planning?showall= & start = 3

  I would use these two RAM sticks for example.

  Module 240 pin DDR3-1333 transcend JetRam™ 8 GB High Performance: CL9, layer 6 circuit board

  Transcend JetRam™ High - Performance 8 GB DDR3-1600 240-Pin Module: CL11, 6 layer PCB, ultimate card stability and cross-platform compatibility

  My question is, what is the best for video editing? On the one hand we have 1333 mhz to with a CL of 9. On the other hand, we have RAM 1600 mhz faster, but at a higher CL of 11. Now, I'm not one to get caught up in the technical aspects as it may seem, but I don't understand so I can make decisions, especially when price is a factor. In this case however, they are at the same price...
  

  Well good for video editing, important criteria for RAM is:

  • Never, never crashes - it is very important; choose only RAM sticks (certified QVL) certified provider and do not use unmatched sticks
  • Speed; faster is better - while true also, past at the speed of the RAM, or lowering of the CASE wait cycles (latency) contribute to the speed, but the gains are very low; Faster RAM is hardly perceptible vs CPU speed more fast which is very sensitive (I played with it a lot on some versions overclock and test first with PPBM speed and speed up the processor 5% performance contributes to 5% where speed RAM about 30% can speed up about 1%)

  Google "what is the CASE for the RAM" and one week at self-teaching yourself if you want to even begin to really understand speed RAM! I know enough to know there is a lot to learn about the subject. The good news is that you don't need really to know a lot to build a reliable, excellent for running Adobe products, including the first, Photoshop and After Effects:

  • Use only RAM who has certified the seller of memory for your motherboard; do not assume that if the seller indicates a set 4x8Go of sticks that will work with your motherboard that two sets of such RAM will work with a card mother 8 locations either! (too late to discuss here, but various factors may override the controller memory in the processor itself - factors include voltage RAM, number of sticks, RAM clock, status of CASE of waiting settings speed, voltage of the cpu memory controller and maybe more)
  • Increasing the speed of the RAM always helps if slightly for first speed up to 1600 MHz (for x 79 in any case) and wins the speed of RAM which are still lighter

  Now, back to why both sets of sticks are the same cost. They most likely use the same chips of RAM, which is an important factor for what it costs to build the RAM sticks. While the Asus motherboard you buy allows full customization of many, many, many things, unless you are an extreme Overclocker and plan to spend a few weeks to fine-tune a new simple version you in the bios of motherboard and it say to use XMP settings. This indicates the motherboard, how to set the speed of the RAM and sticks of timings CASE for your particular RAM with the settings the seller intended.

  You really know a lot about what you are doing to set the timings RAM in any way other than the simple choice of XMP settings safely. And, you can easily burn your CPU if you don't know what you're doing and you choose some really bad parameters.

  Kind regards

• 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

• Questions about scripts in ai2

  Hello
  
  Two questions about the new install script.
  
  (1) where to find documents on the "object model" which is available for use during the writing of scripts. There the Javadocs available to all classes, getters, setters, etc that can be used?
  For example, I want to write a custom rule to detect foreign keys "without columns. For some reason, this error occurs during generation DOF, but I have not found a standard rule of prior design detect these problems before the generation of DDL. So, I'm interested in knowing how to navigate through the object model to create a rule of mine (IE is it a table.getFK (.getColumns ()) use?).
  
  (2) is it possible to use Groovy as a scripting language? If Yes, does anyone have the docs (or even draft notes) on how join as a script engine in the Data Modeler?
  
  Thank you, BP

  Hi BP,.

  to detect foreign keys "without columns. For some reason, this error occurs during generation DDL

  What version did you use to create these cases? There was such a problem in one of the pre-production versions published two years ago.

  Meta definitions, you can watch datamodeler\datamodeler\xmlmetadata directory.
  In fact, it is preferable to define the rule of index/constraint - you will get a clue that is used to represent the PK, UK, the FK constraints and indexes.
  So for your rule, you select index/constraint as object and the next Java scrip will be your rule:
  var index;

  {if (index.isFK () & {index.getElements () .length == 0)}
  fake;
  } else {}
  true;
  }

  If you remove index.isFK (control) then the rule will be valid for all PK, UK, the FK constraints and indexes.

  For script engines - you can start here - https://scripting.dev.java.net/
  I see groovy is supported - http://groovy.codehaus.org/JSR+223+Scripting+with+Groovy
  How to install it - you can follow the instructions in the first link above, it's much easier just to copy related jar in the "ext" directory - for groovy I copied "groovy - 1.7.5.jar" (I downloaded 1.7.5 version)
  in the "D:\jdk1.6.0_20\jre\lib\ext" directory on my computer. You must restart the Data Modeler - I engine script groovy as a choice in the engine drop-down list box.

  You must test how Groovy will return true or false for the Data Modeler - generally ordinary (not library), it is strange that you see in the example. If the library is used then the standard return is used.

• A few questions about the making of the animated for a site Web Nav buttons

  Hello, I have a few questions about creating some animated for a NAV buttons.

  There are 2 actions I want to trigger on pouting above.

  If I want to use a static (PNG) image I created in Photoshop for the real button, can I use that? I want well drag the button down on the passage of the mouse and drag upward on the mouse. If I push the part of the "Web" button (sorry, that it comes from a Photoshop guy) it will disappear in the final animation? Another way to say this, if I put something lively off the coast of the white area, it no longer appears in the movie (.swf) when it is published?

  For the second part. You can see a bit of what I want to do if you look high Nav of the page of the website: http://www.photoshopsupport.com/index.html

  I need the 'light' above the button and it's going to be on another < div > color so I can't put a solid color of BG for my flash document. But I want to get the effect of the 'bar' lighting up above the button and the real key slide downwards to pouting on.

  You can provide any help would be greatly appreciated.

  We target the dynamicaly graph. Since the MouseEvent is now on the invisible sprite and not the graph itself, the one-for-all function has no reference to this graph. You can access the invisible sprite with event.target (or event.currentTarget), you can also target the chart because we declared "mygraphic" custom property to serve as a reference for the graphic. Thus, event.target.mygraphic is the benchmark for graphics.

  Of course, this is just an example. There are other variations of this trick.

• Question about DISCHARGE (expr, 1016) function

  Hello
  
  I have a question about the DUMP function, specifically the DUMP (expr, 1016). What character set is the function of report? The only logical answer seems to me the characters of data. The http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/functions055.htm#SQLRF00635 docs it says: "by default, the return value contains no character set information. To retrieve the name of character of expr, add 1000 to all the values of previous format. "For example, a return_fmt of 1008 returns the result in octal * and provides the character set name of expr.*.
  
  I ask this question because a client complains that there a database with database EE8MSWIN1250 (obtained from DATABASE_PROPERTIES) characters and when I asked him to run a SELECT that could empty the contents of a column, he gave me this result:
  

  select dump(some_col, 1016) from some_table;
  
  Typ=1 Len=8 CharacterSet=AL32UTF8: c5,bd,c5,a0,54,45,53,54

  Now I can't imagine how the data can be stored in the AL32UTF8 character set if the characters of the database are EE8MSWIN1250. This scenario is still possible? I tried in vain to reproduce on my test database.
  
  I don't know if the column is defined with the characters of database or the national database characterset, but even if it was a NVARCHAR2, the dump function could not return AL32UTF8 since he is not a national character set.
  
  If anyone has an explanation, I will be very grateful.
  
  Thanks in advance and best regards,
  Swear

  1. to help with the confusion about the DUMP function: index realizes that the DUMP function can be performed in the remote database. Oracle tries to push as many functions as possible and semantically correct on the remote site. Therefore, it sends the statement of simple table on the remote site after stripping the DB link. In this case, the DUMP function sees the character set of the remote database and creates the resulting string of information. This string of AL32UTF8 to EE8MSWIN1250, as described in the note, but as all the characters in the string of information are pure ASCII, some codes are actually changed.

  Things get more interesting if you start to combine the tables of local and remote databases. For example, the following query is will normally return the character of local database defined for the two columns:

  select dump(xx,1016),dump(yy,1016) from (select x.dummy xx, y.dummy yy from dual x, dual@dblink y);
  

  This is because the first dual@dblink is transported to the local site and the join is performed here with application of DUMP.

  The following query returns the set for two columns of characters in remote database:

  select dump(xx,1016),dump(yy,1016) from (select x.dummy xx, y.dummy yy from dual@dblink x, dual@dblink y);
  

  This is because all the tables are remote and the entire query is sent to the remote database and y.

  The following query returns the remote character set thus:

  select dump(xx,1016),dump(yy,1016) from (select /*+driving_site(y)*/ x.dummy xx, y.dummy yy from dual x, dual@dblink y);
  

  Here, the DRIVING_SITE hint asks the database to perform the join in the database of the table, for example dual@dblink.

  2. to answer your question:

  Your understanding of the way of conversion is generally correct, but conclusions are not quite correct. In the scenario [client EE8ISO8859P2, EE8MSWIN1250 local database, remote database AL32UTF8], Eastern and Central European characters will work correctly, but the other characters to the remote database will not be (for example, French, Greek, Chinese). It is, I think, quite clear and is usually not a major problem, as usually only compatible languages EE8 are interesting for an EE8ISO8859P2 customer. However, in the scenario [customer AL32UTF8, EE8MSWIN1250 local database, remote database AL32UTF8], the problem becomes more visible. Having a taking customer support Unicode, you can recover some data French or Greeks of the remote database but you will fail as all of these characters will be "killed" by the conversion of distance at the local level (link DB conversion).

  EE8ISO8859P2 is also for the same group of languages, such as EE8MSWIN1250, indeed, but it lacks some interesting characters. The most important of them is the symbol of the Euro. Others are "' quotes, long dashes, TM symbol, and a few other less frequently used punctuation. Therefore, always define a database as EE8MSWIN1250, even if you run some clients (Unix) with EE8ISO8859P2. Do not run Windows with EE8ISO8859P2 clients, except for purposes of loading/generation of special file.

• A question about clusters

  Hello
  
  I have a question about the single table hash clusters. How are these paintings in a position to provide better performance? Any block can contain data from a single table, and here was the only cluster table will also create blocks with data from a table. So how or why is it more effective?

  The benefit is provided
  (1) exercise you some control over the way in which the data are filled in the table
  2) most of your questions is a 'SELECT col1, col2,... '. "Col WHERE = "
  (3) the number of values unique 'col' is fairly constant
  The common approach in the situation described above is to create an index on 'col' so that applications may perform better.
  But even with the indexes in place, oracle will need to access the blocks of two segments, index and table, in order to process the requests (of the type described in step (2) above).
  When you create the table in a hash TABLE UNIQUE cluster, you can get the grouping of the data in the table itself, without the need of an index. Oracle will have access to the only segment (cluster) blocks to process requests (of the type described in step (2) above).
  The result is much less number of consistent gets for queries of the type described in step (2) above, resulting in better use of the buffer cache, which improves performance.
  I hope this helps.
