HTTPService caching problem? (PL/SQL backend)

• Oracle result Cache problem

  Hello

  In our database, we have the following settings for caching the result:

  result_cache_max_result integer 5

  result_cache_max_size great whole 256256 K

  result_cache_mode chain MANUAL

  result_cache_remote_expiration integer 0

  But we use indicators no results hidden in questions, or tables that are enabled for result caching.

  So from my understanding, caching the result should not happen.

  But we met a performance problem, and when I checked the AWR report I found this:

  

  And also I found this activity latch:

  

  However, just set result_cache_max_size = 0 fixed to all our questions. Wait no more. Performance as expected.

  But how is that possible? I thought with result_cache_mode = manual and not using indicators of result cache or table modes,.

  There should be no result at all caching? Any max_size choose?

  Can someone help me understand what is happening here?

  Thank you and greet.

  The original poster was not to the point and they actually understand the docs.

  Sorry - I'm not okay. As I went to the docs are very EXPLICIT about how to disable the cache of result. If you turn it off, then it is enabled.

  The fact that they have tried to do is that when result_cache_mode is set to the default value of the MANUAL, because they showed, it is, while according to the docs 12 c only the results of queries that use the RESULT_CACHE indicator must be stored in the cache of result

  Maybe that's where you and OP have misunderstanding. on the RESULT_CACHE_MODE parameter and the parameter values. This seems to be a common misunderstanding.perhaps, because people are not read ALL the relevant articles of the RFSO and only looking at the section for this parameter.

  There is NOTHING in the doc of 12 c for this parameter that shows ANY correlation to determine whether the cache is enabled or not.

  Refer to the section "Setting the Mode of the result Cache"

  https://docs.Oracle.com/database/121/TGDBA/tune_result_cache.htm#CDEJCGJD

  As shown in table 15-3 there are ONLY two settings: MANUAL and FORCE. No adjustment said ANYTHING on toggle or if the cache is ENABLED or DISABLED.

  ... and they were not aware of all the queries that they had used this trick on.  When you're ready to values by default and don't use don't not result_cache indicator (as much), it's odd to find the cache of your result are so full.

  OK - the USER does not use the indicator result-cache to cache the results of the queries USERS. But if the cache is enabled (size not equal to zero) that according to the quote from the doc above has NO effect on the use of Oracle to cache for queries or non-deterministic function calls.

  I think a lot of people may be jumping on the server I mentioned first that article explicitly states that you must set the size to zero to disable hide and seek only to the section on setting the parameters.

  And that the "setting mode" section is confusing as it includes a paragraph that uses the expression "If you choose to activate the result cache.

  That subsection and the r-phrase likely cause people to think that the setting and the off/on State of the cache are one and the same.

  When the result cache is enabled, the database also highlights cache queries that call non-deterministic functions of PL/SQL. When caching SELECT statements that call functions, result cache dependencies of data for PL/SQL functions and titles of database objects. However, if the function uses the data that are not followed (such as sequences, SYSDATE , SYS_CONTEXT and package variables), uses the cache of result on queries that call this function can produce stale results. In this regard, the behavior of the cache of result is identical to the caching of PL/SQL functions. So always consider the accuracy of the data, as well as performance, if you choose to activate the result cache.

  But if all associated sections are interpreted in their context, it should clear up the misunderstanding.

  If you have a support contract, you can submit a request to have the documentation changed to update mode setting (table 15-3) article to explicitly declare the parameter mode does NOT determine if the cache is enabled or not.

• Connection problem with SQL Developer 3.0.0.4

  I have a strange problem with SQL Developer (SD) 3.0.0.4. So that the implementation of a new connection I have in double entries listed for some of the databases listed in my TNSNAMES.ora file. When I try to connect to one of the databases has entered duplicated, I get the following Oracle error:

  ORA-01034: Oracle not available ORA-27101: Kingdom does not exist SVR4 shared memory error: 2: no files or directory

  however, if I try to connect to the same database using SQL * more or TOAD, it works perfectly and TOAD has no duplicates.
  
  At first, I thought maybe that SD has been reading multiple copies of the TNSNAMES.ora so I checked and removed all the duplicate files and set the variable of environment TNS_ADMIN to point to that and the single instance of the TNSNAMES.ora file. Yet once, SQLPlus and TOAD to work fine, but SD is always showing entries twice and always have reported the above error when I try to connect to a database with a duplicate entry. I should mention, I'm able to connect to the database that have only a single entry listed use SD.
  
  If I understand correctly, SD uses JDBC as underlying connection mechanism. Based on this "agreement" I thought that maybe I had a file corrupted in the Java Cache, so I cleared the cache, but I always get errors.
  
  As mentioned, I use SQL Developer 3.0.0.4 with Java 1.6.0_11 (included in the download). In addition, I have installed JRE 1.6.0_24 and I am running Windows XP SP3. Any ideas or suggestions are greatly appreciated.
  
  Craig...

  Hi Craig,.

  Or, if I have misunderstood completely the scenario you describe, here's a post on the forum about duplicate entries appear in the drop-down list Alias network when the connection Type is TNS:

  Developer SQL 2.1.0.63 TNS name in characters of the connection

  This solution involves clean a bad TNSNAMES. ORA file with double score entries to test the death of SID.

• problem starting sql developer 4.1.1.19.59

  Hello

  I installed SQL developer 4.1.1.19.59, but when I start it up it crashes on the login window for the proxy server that is not responding. I can't even shut it down, and the only way is to kill the process with the Task Manager.

  An administrator can run the program, but I'm not an administrator on my PC.

  I'm runnning Windows 7 Professional 64 bit.

  Can someone tell me what permissions are needed to facilitate this run as a normal user?

  P.S. I don't have this problem with SQL Developer 4.0.3.16.84

  Thanks, Wouter

  HI Wouter,

  In fact, my advice was r ide.user.diuse to replace the default user settings folder.  Under normal circumstances the default value of %APPDATA%\SQL developer and the problem is usually an administrative policy that prevents updates records and files in %AppData%.

  My expectation was so you would set ide.user.dir to something other than a folder under % APPDATA %., maybe C:\Temp\OSD, to see if it works.

  Kind regards

• OBIEE buffer or Cache problem?

  I was recently working in OBIEE as administrator and access modifiers to allow a certain group access to a specific area.

  After going through settings-> Administration-> manage privilege I added the group to the area in question.

  It took almost 1 hour to make the changes take effect.

  Anyone know why that would happen?

  What is a buffer or a cache problem?

  During development, we cannot afford to have this down in the test of time.

  It seems to happen very rarely, but it would be good to pin point what exactly is the root cause.

  Thanks in advance

  It's a cache problem, sometimes it can take time to cool off.

  Let me know if you need more info on this.

  Check if helps,

  Thank you

• Problem with SQL Loader ODI

  Hello
  
  I have problems using SQL Loader with ODI. I am filling an oracle table with data from a txt file. Initially, I had used 'File to SQL' LKM, but due to the size of the file (700 MB) source, I decided to use 'file to Oracle (SQLLDR)' LKM.
  The error that appears in myFile.txt.log is: "SQL * Loader-101: invalid argument for the name of user and password.
  
  I think the problem might be in the definition of the database server (physical JavaBeans in topology), because I left empty Host, user and password.
  
  What is the problem? What host and user should I use? With "File to SQL" works fine living that white, but takes too much time.
  
  Thanks in advance

  Note the last * @*. He expects a connection string after him.

  So, goto Oracle server topology, specify Instance/Dblink (server) as the SID of the oracle database you want to connect.

• After the connection to connect to a page depending on the user - cache problem?

  Hello
  
  In my application I want to have the branching page after login: according to the user and registration data must load another page.
  
  Is what I did in the login page 101:
  -J' created a hidden element P101_GOTO_PAGE.
  -J' created an after submit processes Login_page_switch (Seq.Nr. 15) with source code:

  DECLARE
   v_bestand_rec apex_bestand_v%ROWTYPE; -- Datensatz Bestand
  
  BEGIN
   SELECT * INTO v_bestand_rec
   FROM apex_bestand_v
   WHERE id = (SELECT max(id)
       FROM apex_bestand_v
       WHERE kstyp = 'Einwohnergemeinde');
   
   IF (lower(:P101_USERNAME) = 'fstberts') THEN
        :P101_GOTO_PAGE := '3';
   ELSE
        IF v_bestand_rec.retyp = 'Voranschlag' THEN
             :P101_GOTO_PAGE := '1';
        ELSIF v_bestand_rec.retyp = 'Rechnung' THEN
             :P101_GOTO_PAGE := '11';
        END IF;
   END IF;
  
  END;

  -J' changed the source builtin login process (Seq.Nr 20) code, to:

  wwv_flow_custom_auth_std.login(
      P_UNAME       => :P101_USERNAME,
      P_PASSWORD    => :P101_PASSWORD,
      P_SESSION_ID  => v('APP_SESSION'),
      --P_FLOW_PAGE   => :APP_ID||':1'
      P_FLOW_PAGE   => :APP_ID||':'|| :P101_GOTO_PAGE
      );

  In general, it seems to work. But the behavior is erratic, branching seems to be influenced of the last logged-on user. So I assumed a cache problem.
  
  I have created a process clear page (s) Cache (Seq.Nr. 20) for the 101 page, which did not help. This process before others (e.g. Seq.Nr. 20) I can not connect more of the school (invalid credentials).
  
  Someone has any idea how to solve this problem?
  
  Thanks in advance,
  Roger

  To disable the links deep (to ignore the page requested by the user), that in the process of connection before calling the API of connection:

  apex_util.set_session_state ('FSP_AFTER_LOGIN_URL', null);

• The problem with SQL after the migration of the database to another machine

  Having a SQL strange problem trying to extract a database being moved from one machine to the other.  Both machines are running SQL 2008 32-bit and are both Windows 2008 servers.  When I try to backup the database using the SQL tools and restore the. BAK file on the new SQL Server, I get the following error:
  
  Restore failed for server 'servername' (Microsoft.SqlServer.Smo)
  Additional information:
  System.Data.SqlClient.SqlError: RESTORE detected an error on the page (44:2097184) in database 'RestoreDBName' read from the backup set.
  
  Similarly, when I am trying to copy the. MDF and. LDF files to the new server and tie them, I get the following error:
  
  Attach the database failed for the server 'servername '.
  Additional information:
  An exception occurred during the execution of a Transact-SQL statement or batch.
  A system assertion failed.  An assertion failure is usually caused by a corruption of data or software bug.  To check the database, consider running DBCC CHECKDB.  If you have agreed to send images to Microsoft during installation, a mini dump will be sent to Microsoft.  An update can be an available from Microsoft in the latest Service Pack or a QFE from Technical Support.

  PID: 292876 (Microsoft SQL Server, error: 3624)
  
  Everything I've read, these errors usually indicate some sort of database corruption.  However when I run DBCC CHECKDB on the database on the source server, it is up to perfectly don't own... None detected corruption.  In fact, this server hosts 8 different databases.  Departure from all the correct DB on the source server, none of them will restore however to a new server using one of the methods above.  I'm having a hard time to believe that each of them could be corrupted when they show absolutely no indication of a problem.
  
  Anyone have any ideas?

  Try to make the backup and restore via SQLCMD (or via a query in SQL Server MS window).

  The backup will be the following (obviously, change "MaBase" and "D:\BACKUPS" to some database and the location you wish to save - just using for example):

  BACKUP DATABASE MyDatabase

  TO DISK = 'D:\BACKUPS\MyDatabase.bak. '

  WITH NOFORMAT, NOINIT,.

  NAME = 'Database MyDatabase - Full Backup',

  NOREWIND, NOUNLOAD, STATS = 10, SKIP

  Copy your backup to the other server and file make:

  RESTORE the DATABASE to MyDatabase

  FROM DISK = 'E:\Backups\MyDatabase.bak' WITH FILE = 1,

  GO to "MyDatabase_Data" to "E:\SQLDATA\MyDatabase_Data.mdf,"

  GO to "MyDatabase_Log" to "E:\SQLLOG\MyDatabase_Data.ldf,"

  NOUNLOAD, STATS = 10 REPLACE

  Again, change your names and locations in function.

  If this does not work, try to restore a database by third-party tools. You can find them in Google. If you don't want to spend the time to research, you can try a tool SQL Server Recovery Toolbox. All the details about this program on the link. http://www.oemailrecovery.com/sql_repair.html

• Problem connecting SQL toolkit Win7

  I use CVI 2013 and tto toolkit (2.2) of SQL to connect to a mySQL database.  I can connect to properly using my development computer, but not with the target.  Both computers are running 64-bit Windows 7 Professional (SP1).  I used to start the 64-bit ODBC drivers (mysql-connector-odbc - 5.3.2 - win64.msi) on both machines.  After I got hurt, I found an article in the Knowledge Base which indicated that I should probably use the 32-bit instead.  So I deleted the drivers of the target and installed those 32-bit using odbcad32.exe found in Windows/SysWOW64.  No change.

  I use the sample browser2.prj project included with the SQL Toolkit (default: C:\Users\Public\Documents\National Instruments\CVI\samples\sql\apps) to test the functionality of the SQL tool.  I create a distribution kit, including the runtime shared on the development computer and install it on the target.  I traced the problem to the call of DBSources() - it returns a - 100 (who, the hand is not among the list of database error codes).

  On both machines the ODBC drivers seem to work.  I can get to the database using Panel-> administration-> Data Sources (ODBC) tools.  Select the user DSN or system DSN database, and then click Configure open the MySQL Connector/ODBC Data Source Connection window.  By clicking Test in this window will connect to the database.

  If the problem seems to lie in the way that ICB connects to the database.  I'm naïve now, any suggestions would be greatly appreciated.

  Sorry if this is a stupid question:

  Have you followed the instructions help-> Reference Library-> library Toolkit SQL-> SQL language reference-> distributing a SQL Toolkit executable or a DLL?

  Or is it a mistake you get despite following these instructions?

• MUI cache problem

  I use WinXP SP3 and keep up-to-date on all critical updates. Lately, I've noticed that institutionalized my computer slows down significantly. When it does I have run Norton Utilities and check the regestry. When I do, the MUI cache is always appear as missing or invalid. I then Norton Utilities fix this and other problems that come up. After the correction, my computer returned to run at its normal speed. I have a good idea of preety what is the MUI cache, but I don't understand why it keeps going missing or invalid.

  Norton is probably the reason why your system is running slowly - it's knowledge that memory and CPU hog, I will never install or recommend for this reason alone and suggest you to consider something with a smaller footprint and less fresh generals like Microsoft Security Essentials and complete it with the free version of MBAM and SAS.  Your sytem will reward you with much better performance.

  I appreciate the fact that some people love their Norton/Symantec products, but they will slow down your system.

  If you look in the forums of Norton on your question, you might meet this opinion of Eric Carlstrom, a technical product manager for Norton/Symantec employee:

  If you do the repair and the same item appears in later analysis, it is probably due to a transitional reference.  Unfortunately, it is very difficult to take into account.  When this happens, it of OK to click with the right button on the item, and then choose ignore during future scans.

  I can tell you that advice from the Support Engineer to run sfc /sannow will not help you and you don't have symptoms suggestive of a need to run sfc/scannow.  This isn't how it works, this isn't what he does and is not what it is for.   To me, this idea out of the blue with no symptoms indicating that it is necessary, means "I don't know what the problem is or how to fix.  It's just another one of there Support Engineer goose chases wild.

  If you chose to replace your Norton with MSE, be sure to use the Norton removal and uninstall tools that you can find here:

  Give a MSE and see how your system behaves.  If you find that you will not care for it, you can uninstall and reinstall your Norton new, right?

• PNDH Cache problem

  I have a DMVPN without IPSEC configuration. My one hub is connected to 10 rays through pure WILL and I'm running OSPF. I put my holdtime PNDH = 5 minutes. When 5 minutes idle time is passed, I'm doing a show ip PNDH and find that the connection has expired remains still in the cache as below:

  tunnel created 05:15, expired

  The cache is in conformity with the provisions only disappear at 6 minutes. If I do a ping between 5 and 6 minutes test, query time-out is obtained. My ping test begins to become the positive response that after 6 minutes where the cache is in conformity with the provisions is removed and replaced with a new one as shown below:

  tunnel created 0:05 expiring 04:55

  How to make the cache disappear immediately for 5 minutes so that I have lost connection for 1 minutes, it is between 5 and 6 minutes?

  Thank you very much.

  The problem is documented as bug CSCdy45826. You should probably upgrade to the version where this problem has been fixed.
