Huge number of Discovere server sessions!!!

Hi All,
Today suddenly the reports ran slow, when i checked the application server middle tier, i found that the discoverer was down.
When i checked for middle tier opmnctl status, i saw a large number of discoverer sessions, can any tell what could be the reason, is it that the users are not clicking on "exit" after running reports?

Hi Roger
Thank you for the reply but both the reason you have given doesn't apply to this server.
RMS emulator is another Management server and For testing I have moved all the agents off this server. No agents are pointing to this server but one of the Reporting server or web console server is pointing to this server.
SO even Server is generating more than 65000 events in 4hrs is normal?
Thank you

  • Lightroom or Photoshop Elements for administrating huge number of photos?

    Dear photo experts,
    at home, we have a huge number of photos we took over years. We are looking for a software able to organize all of them. We currently have:
    Adobe Photoshop Elements 10 (Mac)
    Adobe Lightroom 3 (Mac)
    However, for organizing photos we so far use none of them but a third software (here, we are not happy about how it handles our huge catalog of photos).
    Our photos are stored on a server (network attached storage), organized by date and event.
    I read that Adobe Photoshop Elements cannot organize photos stored on a network drive.
    Now my questions:
    - Can Adobe Lightroom organize photos stored on a network drive?
    - Is Adobe Lightroom capable to organize a huge amount of photos in one single catalog (separating them via tags)?
    What are your experiences?
    Thanks a lot!
    JMickey

    I read that Adobe Photoshop Elements cannot organize photos stored on a network drive.
    I thought the opposite was true
    Can Adobe Lightroom organize photos stored on a network drive?
    As we say here in Rochester, NY, YES it can
    Is Adobe Lightroom capable to organize a huge amount of photos in one single catalog (separating them via tags)?
    Yes, this is one of Lightroom's strengths
    What are your experiences?
    I use Lightroom for all of my photo management (yes, I said ALL). I never use the operating system for photo management. Lightroom works great. People here in this forum who have much larger catalogs than I do (over 1/4 million photos) also use Lightroom to manage their photos.

  • Application Server Session timed out (-11) (lack of debug in internal ITS)

    Dear Sirs,
    I get the error message below, when I try to run a IAC through internal ITS. The IAC worked for a while (<30 minutes), and then suddenly this error appeared.
    I can see that this error message has been asked about previously, but then in connection with statefull/stateless BSP applications (e.g "Session timed out thread", on this forum May 31 2005).
    In this thread the solution is apparently to alter the 'rdisp/plugin_auto_logout', is this the case for us as well?
    I have read Error handling using the ICM , but not able to actually beeing able to pinpoint the problme.
    All our other IAC are working it is only a problem with one of them. The problem is still valid even if I log on with different user, and the error is still there now even after two hours. The problem transaction is a altered version of the WSTA, and I am able to get the first screen where I enter the store number. 
    Any tips or suggestions to pinpoint the error?

    Dear Sirs,
    The error has been solved. It was a matter of an illegal input sendt to the RetailHeaderFunction.
    However, this makes way for another question.
    On the standalone ITS, it was possible to get error messages which indicated where the code contained errors, when it was runned.
    How is it possible to make the internal ITS gives better feedback (errors?), and show where the error is?

  • Discoverer Server doesn't work (OAS 10.1.2)

    Hello, I tried to create connection in Discoverer Plus service of Oracle Application Server 10g Release 2 (10.1.2). But I get an error as an answer and suggesion:
    An administrator can further diagnose connection problems by running the "checkdiscoverer" script under <ORACLE_HOME>/discoverer/util.
    This script tells:
    Checking for Discoverer "ServicesStatus"...
    "ServicesStatus" is running.
    Checking the adminstrator set soft limit on no. of sessions ...
    Current value of soft limit = 50 sessions.
    Hint: Administrators can increase the soft limit on Discoverer sessions by modif
    ying
    "//ias-component[id='Discoverer']/process-type[id='SessionServer']/process-set/@
    maxprocs" attribute in the file C:\Oracle\product\10.1.2\oracleAS\apps\opmn\conf

    Heap memory size = 512 KB
    The amount of memory allocated seems to be less. You will not be able to start m

This value is most derived from the PROCESSES parameter. You cannot exceed this number of sessions unless you raise the parameter value.
    If your database is configured to handle enough sessions, then Oracle can literally handle thousands of simultaneous connections, provided your database server also has enough resources to handle this number of connections. You will want to implement Oracle's Shared Server connections so that multiple connections share a pool of processes on the database server. This minimizes the resource consumption used by the connections.

  • Unable to connect Discoverer Server:IDL:DCCORBAException:1.0

    Hi all,
    I installed Discoverer 10 server on a machine called gnvmig.ote.gr and when I connect (from Discoverer Plus) to an Application EUL on the same machine I don't have any kind of problem. If I try to be connected to an Application EUL on another machine I have the following error:
    Unable to connect Discoverer Server:IDL:DCCORBAException:1.0
    I added inside the tnsnames.ora the connection string (to the other machine) and I enabled the trace....but inside the apps_trace.txt I don't any errors.
    The strange thing is that the connection on the remote machine worked perfectly since yesterday....and now....nothing !!

    Maybe should I create it and copy some .dbc files inside ?
    But if the answer is 'YES', how did it work until yesterday ??? I have the suyspect that something has changed on the Application envinronment....
    Any help will be appreciated
    Thanks in advance

    If you always get this error, then I don't know the answer. However, I see this message if I try to open a second Discoverer Plus session from the same browser session (either the same connection dialog, or on another tab of the same session). You can have multiple sessions of Discoverer , but they must be opened from completely separate browser sessions, or different browsers.

  • Slow due to huge number of tables

    Hi,
    unfortunately we have a really huge number of tables in the ( Advantage Server ) database.
    About 18,000 + tables
    Firing the acitveX preview thru RDC, or just running a preview in the designer slows down to a crawl.
    Any hints? ( Besides get rid of that many tables )
    Thanks

    Hi Oskar
    The performance of a report is related to:
    External factors:
    1. The amount of time the database server takes to process the SQL query.
        ( Crystal Reports send the SQL query to the database, the database process it, and returns the data set to Crystal Reports. )
    2. Network traffics.
    3. Local computer processor speed.
        ( When Crystal Reports receives the data set, it generates a temp file to further filter the data when necessary, as well as to group, sort, process formulas, ... )
    4. The number of record returned
        ( If a SQL query returns a large number of records, it will take longer to format and display than if was returning a smaller data set.)
    Report design:
    1. Where is the Record Selection evaluated.
        Ensure your Record Selection Formula can be translated in SQL, so the data can be filtered down on the Server, otherwise the filtering will be done in a temp file on the local machine which will be much slower.
    They have many functions that cannot be translated in SQL because they may not have a standard SQL for it.
    For example, control structure like IF THEN ELSE cannot be translated into SQL. It will always be evaluated in Crystal Reports. But if you use an IF THEN ELSE on a parameter, it will convert the result of the condition to SQL, but as soon as uses database fileds in the conditions it will not be translated in SQL.
    2. How many subreports the report contains and in section they are located.
    Minimise the number of subreports used, or avoid using subreports if possible because
    subreports are reports within a report, and if you have a subreport in a details section, and the report returns 100 records, the subreport will be evaluated 100 times, so it will query the database 100 times. It is often the biggest factor why a report takes a long time to preview.
    3. How many records will be returned to the report.
       Large number of records will slow down the preview of the reports. Ensure you only returns the necessary data on the report, by creating a Record Selection Formula, or basing your report
    off a Stored Procedure, or a Command Object that only returns the desired data set.
    4. Do you use the special field "Page N of M", or "TotalPageCount"
       When the special field "Page N of M" or "TotalPageCount" is used on a report, it will have to generate each page of the report before it displays the first page, therfore it will take more time to display the first page of the report.
        If you want to improve the speed of a report, remove the special field "Page N of M" or "Total Page Count" or formula that uses the function "TotalPageCount". If those aren't used when you view a report it only format the page requested. It won't format the whole report.
    5. Link tables on indexed fields whenever possible.
    6. Remove unused tables, unused formulas, unused running totals from the report.
    7. Suppress unnecessary sections.
    8. For summaries, use conditional formulas instead of running totals when possible.
    9. Whenever possible, limit records through selection, not suppression.
    10. Use SQL expressions to convert fields to be used in record selection instead of using formula functions.
    For example, if you need to concatenate 2 fields together, instead of doing it in a formula, you can create a SQL Expression Field. It will concatenate the fields on the database server, instead of doing in Crystal Reports.
    SQL Expression Fields are added to the SELECT clause of the SQL Query send to the database.
    11. Using one command as the datasource can be faster if you return only the desired data set.
          It can be faster if the SQL query written only return the desired data.
    12. Perform grouping on server
       This is only relevant if you only need to return the summary to your report but not the details. It   will be faster as less data will be returned to the reports.

    Dear Deepak,
    This is what I am talking about. This session information only shows 1 session of apache.
    However many users are connected to apache more then like 250.Are you trying to figure out how many different users are using Apache? Or how many sessions exist in the database? In a three-tier environment, you almost always have a connection pool, so the number of hitting the middle tier is substantially different than the number of sessions in the database.
    What is the business problem you are trying to solve? Is this a licensing question? Or a technical question? If it is technical question, what problem are you trying to solve?

  • Huge number of garbage collected objects

    We're running a system here with the java heap set to 256mb and have noticed
    that now and then, garbage collection takes a horribly long time to complete
    (in the order of minutes, rather than fractions of a minute!). Something
    like 3 million objects are being freed when the server is heavily loaded.
    Has anyone else experienced this behaviour? Has anyone tested weblogic with
    JProfiler/OptimizeIt and found any troublesome spots where many objects are
    created? One potential place where this can be happening is in the servlet
    logging. Since there is a timestamp that is a formatted date, my guess is
    that a new Date object is being created, which is very expensive and hence
    might cause many more objects that need to be garbage collected. Can any
    weblogic engineers confirm/deny this?

    Use vmstat to determine if you're swapping. sar would work too.
    Swapping is definitely dictated by the OS, but an inordinate amount of
    swapping activity just means you get to tune the hardware rather along
    with the application.

    If GC takes on the order of minutes to run then I suspect that you

  • Huge number of unprocessed logging table records found

    Hello Experts,
    I am facing one issue where huge number of unprocessed logging table records were found in SLT system for one table. I have check all setting and error logs but not found any evidence that causing the unprocessed records. In HANA system also it shows in replicated status. Could you please suggest me something other than to replicate same table again, as that option is not possible at this moment.

    Hi Nilesh,
    What are the performance impacts on the SAP ECC system when multiple large SAP tables like BSEG are replicated at the same time? Is there a guideline for a specific volume or kind of tables?
    There is no explicit guideline since aspects as server performance as well as change rate of the tables are also relevant. As a rule of thumb, one dedicated replication job per large table is recommended.

  • Implementing PaaS (CloudFoundry/BOSH) feeds a huge number of (unwanted) ProtectionServers into DPM

    Hi
    We have a Hyper-v cluster with VM's on Cluster Shared Volumes, we are using System Center (2012 R2) VMM and DPM for backing up the core infrastructure and a selection of vm's from some of our VMM clouds.
    Ongoing work is to implement a PaaS with Hyper-V/System Center - with use of CloudFoundry/BOSH. Due to a lot of unity tests many short lived vm's are made that we never want to backup with DPM. It looks like that the DPM Agent on the Hyper-v hosts in the
    cluster feeds all vm's that it sees into DPM as a ProtectionServer - even though these VM's do not have any DPM Agent installed.
    Doing this SQL in the DPM Database:
    SELECT count(*) FROM [DPMDB_MyDPM].[dbo].[vw_DPM_Server]
    Gives 5531 entires. A huge number of these entires are from the PaaS CloudFoundry/Bosh created VM's in the IaaS. These are VM's that never have been backed up by DPM (Or have any DPM agent installed).
    We see the same with use of powershell:
    PS C:\> $ps = Get-ProductionServer | Where-Object {$_.Name -like "*bosh_vm_being_created*"}
    PS C:\> $ps.length
    5294
    PS C:\>
    * The huge number of (unwanted) Production Servers in our DPM causes that our DPM is going slower and slower. And we see that our DPM SQL Database is working more and more. Today we are only taking backup of around 20 VM's, the SystemCenter MSSQL and a few
    hosts with DPM agent.
    Question 1 - How can we remove these unwanted ("bosh_vm_being_created") ProductionServers from our DPM? They do not have any DPM agent installed, they have no recovery point in DPM. But still they are listed in DPM as a ProductionServer. Why?
    Question 2 - How can we configure DPM to filter out these PaaS/CloudFoundry/Bosh VM's so that they do not reach the DPM system?

    Hi
    Unfortunately I have no solution on my case yet. The number of ProductionServers in our DPM server is growing and growing. And our DPM is going slower and slower.
    PS C:\> $ps = Get-DPMProductionServer -DPMServerName <DPMhostname>
    PS C:\> $ps.length
    8525
    PS C:\>
    It must be an purg-job that is not cleaning out old VM's (objects) from the DPM server I guess. I our VMM we only have around 200 VM's. So most of the ProductionServers in our DPM is old VM's that no longer exist.
    When we try to use
    Remove-ProductionServer.ps1 powershell to remove one of these ProductionServers - we get an error because the VM do no longer exist (and the VM do not have any agent installed).
    Do anyone have any experience with this?

  • How to change port for discoverer server

    Hi All,
    Current default port is 7777 for discoverer server.
    how to change the port number ?
    Thank you.

    [Disco Configuration Guide|http://download.oracle.com/docs/html/B13918_03/maint.htm#i1035783]
    Hi,
    I would recommend using the Oracle Business Intelligence Discoverer Configuration Guide appropriate for your implementation (e.g. for Oracle BI Discoverer 10g Release 2 for SPARC, click on the link above). Here is what the documentation says:
    To change the port on which Discoverer is deployed:
    -Start Oracle Application Server Control and display the System Components page (for more information, see Section 5.1.2, "How to start Application Server Control and display the System Components page").
    Display the Ports tab
    -In the rows containing the Oracle HTTP Server component (Type=Listen), select the edit icon in the Configure column to display the Server Properties page for that component.
    -Scroll down to the Listening Addresses and Ports area and change the port number in the Default Port field.
    -Click OK.
    -When you are prompted to restart the Oracle HTTP Server, click Yes.
    For more information about the Server Properties page in Application Server Control, see Application Server Control Help.
    Hint: If you change a Discoverer port number, make sure that any other OracleAS components that use that Discoverer port number are synchronized.
    I have not needed to do this, so I can not speak from experience. As always, try this in a test environment first.
