Instance dead.. by os?

Hi all,
this night one db has shutted down unexpectedly.
This is what i got from trace:
*** SERVICE NAME:(SYS$BACKGROUND) 2007-06-15 02:00:38.058
*** SESSION ID:(325.1) 2007-06-15 02:00:38.058

and from alert:

CKPT: terminating instance due to error 4030
Version 10.1.0.4 on win 2003sp1 (i swear.. not my fault!)
At that hours rman was backing up the db.
I think that the machine run out of memory and os tried to "stole" it from db.
So oracle prevent data corruption by shutting down the instance.
Any ideas?
ps..
Actually everythings seem to be ok. I just wish to avoid this situation again..
Thanks
Acr

Version 10.1.0.4 on win 2003sp1 (i swear.. not my fault!)Is this a 32-bit system?
If yes i think you have a problem with the 2GB (or 3GB) limit. If i am right, you don't have any chance on windows (because of the implementation with threads!).
You can use the following query to determine the usage of memory (without process stack and code size):
select sum(bytes)/1024/1024 MB from
(select bytes from v$sgastat
union
select value bytes from
v$sesstat s,
v$statname n
where
n.STATISTIC# = s.STATISTIC# and
n.name = 'session pga memory'

  • Determining ORACLE_HOME of a dead Instance

    Db version 10g Release 2
    OS: AIX
    Lets say a machine have 3 dead instances(oraprod45, oraprod46, oraprod47) and now i want to bring up oraprod45. But this machine doesn't have an oratab file and oraenv due to a slightly flawed installation. How can i know the ORACLE_HOME of oraprod45?
    Message was edited by:
    GarryB

    Thanks everyone.
    Two questions:
    1)So which is the best way to determine ORACLE_HOME
    of a dead instance?
    Is this something you inherited and now have to get back on its feet with no good documentation?
    If there is no oratab, I'd say the installation was more than 'slightly' flawed!
    There's no simple formula. You'll have to do some detective work.
    1) Do you have any reason to believe there is more than one Oracle home?
    2) Where is your listener.ora and sqlnet.ora? They should be in $ORACLE_HOME/network/admin, so if you find them in a <something>/network/admin, the <something> should be the value of ORACLE_HOME.
    3) While there are no guarantees, (see my reply to Jaffy) I'd still look at the .profile for the oracle os account and see if there are any clues there. If there are, and they match what you found in step 2, I'd be comfortable in going with that.
    4) report back what you find and we'll go from there.
    2) How can i make the listener automatically attach
    to a newly created instance? ie. How to enable
    Self-registration for a listener?Listeners don't attach to instances. They listen for and service connection requests. In 10g, instances self-register by default.

  • Dead instances in corba mode on Mac OSX

    Hello,
    Since our transition to IDS CS5 we often experience that corba instances run into a dead-lock randomly.
    With a dead instance, i mean that the process is still running, the ior file still exists and seems to be valid (the contentstring is the same as on startup), but the application object is lost. It occurs randomly somewhere during execution of our code and almost always on a different part of our code.
    I can simulate this state of IndesignServer by running a corba instance on my MacBook Pro, closing the MBP and wait for about an hour. Then reopen it and trying to connect. Then i get:
    org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No

    This is exactly what i get on our customers servers (which don't "go to sleep" obviously). Just setting my MacBook Pro to a very short sleep time (1 min.) doesn't invoke this error. This makes it hard to simulate the problem. Apparently the sleep invoked by closing the MBP and waiting an hour isn't the same as putting it asleep, all parameters on, after 1 min.
    All OSX versions are 10.6
    So i have two questions:
    1) What are the possible causes of those dead-locks? Errors in our code (both java and our own IDS plugin) normally cause a real instance crash which is traceable.
    2) Is there a way to re-establish a connection to a dead instance?
    Thanks in advance for any input!
    Bart Devos.

    No one any input? It becomes a real problem reported by several of our customers since we changed to CS5.
    Can anyone point me into possible directions we should investigate?
    What we checked already:
    1) If no more than 1 thread accesses an instance at a time.
    2) We checked out what the error log really meant. We found out that this problem was reported since java 1.4.20. We compile all code for 1.5, but customers work java 1.6.24/26. No idea if this is an issue.
    3) We checked out the ORB string and found out that the connection was made with an ipaddress and not with a servername, excluding dns problems.
    We are really stuck here.
    Thanks in advance for any usefull input.
    Bart Devos.

  • Unable to delete dead instances

    Due to somethin g wrong happened (shuch as an abnormal end or crash), it seems that the oidmon tables contain wrong information.
    Now trying to stop oidmon also tries to stop non-existing processes. And so oidmon hangs.
    Here are messages displayed in oidmon log:
    2001/06/29::11:01:24: Could not delete the Instance
    2001/06/29::11:01:24: OIDLDAPD Instance 2 deletion failed
    2001/06/29::11:01:24: Cannot Stop server instances with PID 0
    2001/06/29::11:01:24: Deleting OIDLDAPD instance 4 from Process table
    2001/06/29::11:01:24: Instance cn=instance4,cn=osdldapd,cn=subregistrysubentry not found.
    I'm looking for any method to refreshing info for oidmon, thus seeting its internal tables into consitent state.

    hi,
    Try restarting your oidctl processes with
    the argument flags=" -f" on the oidctl command line. Use other arguments to oidctl as you did previously, before the processes were killed abnormally.
    eg,
    oidctl connect=xxxxxx server=oidldapd instance=4 flags=" -f" start
    The -f flag means "force" this command to overwrite oid info in the database.

    Corrected typo: ora 12530 was the original error reported, not 12503.

    nothing in the alert. no traces, dumps, nothing. A switch last night Mon May 7 22:10:05 2012, and the PID kill from that SQL session with error 472 which I know is something external killing the instance. Im not too bothered by this though, Ive never EVER seen an instance be open with out the corresponding OS processes

    On the other hand, there are those of us that appreciate the theft protection provided by the latest IOS.
    There are certain things to watch out for when purchasing used devices of any sort, the first of which is to ensure that you're not buying stolen property.  Since you are unable to obtain cooperation from the seller, perhaps your device was stolen!

  • Multiple instances of same portlet on same page

    Dead horse, I know, but I am afraid I still don't get it:
    I use ONE JSP to extract data as XML, parse the data using XSL, render it. A portlet has some variables that may vary between instances of the same portlet on the same page. I am familiar with this document: http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/ARTICLES/PRIMER.PORTLET.PARAMETERS.EVENTS.HTML
    but still don't know how to make sure that every portlet gets it's 'own' parameters passed. I pass them and attempt to grap them in the jsp using request.getParameter().
    I have played with making each parameter unique using the portlet instance name followed by a '.' and a name, e.g. 35024_LISTPORTLET_49519321.next_page=10.
    Setting passAllUrlParams in provider.xml to true helps getting the parameters through, but the side effect is, of course, that all instances get mixed up. Setting it to false does nothing.
    PLEASE, is there, somewhere, a document that tells us EXACTLY how to do this? JDev 10g, as10g.
    Tnx.

    Have you read the Public Portlet Parameters Support section of the Portal Developer's Guide?
    The question is who passes the parameter to your portlets. If the parameters are passed from within the portlet instance itself, use qualified private portlet parameters. If they're passed from the outside, use page parameters and public portlet parameters.
    Hope this helps.

  • Multiple instances of FileOutputStream

    Hi, I'm learning how to use Java's multithreading features. I created a class called "ObjectMaker". An instance of this class serializes some objects into a file, using a FileOutputStream (inside an ObjectOutputStream) for writing. In the mean time an other object of another class deserializes those objects reading from the file. Each concurrent access to the file (for writing,reading) is synchronized. Here's the problem:[ u]if each writer has its own FileOutputStream, then the concurrent writing on the file doesn't work (despite of every writer is synchronized on the same object), and the reader aren't able to read anything from the file; if the FileOutputStream is static (every instance share the same FileOutputStream reference) everything works. I read on Documentation that some OS "allow a file to be opened for writing by only one FileOutputStream (or other file-writing object) at a time" .But it also says that I would recive an exception from FileOutputStream if I try to open a file for writing that is already open by another FileOutputStream....and It doesn't happen, no exception are thrown.Then here is the problem:It's possible to manage Multiple instances of FileOutputStream linked on the same file?

    Hello Joseph,
    Have u been successful on the installation.
    There were no replies after yours.
    Can you please let me know about installing 2 MDS instances on the same host.
    If you have any document you followed please mail me to [email protected]
    It will be more helpful as the dead line to this is killing me.

  • How many workbook can be broadcasted with 1 resgistered precalc instance

    Hi all,
    i did what you said now i have another question you have mentioned to register 10 instances of the precalculation server on 1 desktop machine, but SAP recommends to register 3 instances in the documentation from matthias nutt. Now the question :
    Is there a restriction? How many workbooks can be scheduled and sended via email when having 1 precalculation instance registered in RSPRECADMIN?
    Or does it depend on the workbook size and hardware configuration of the desktop? What is therefore recommended from SAP?
    Thanks and kind regards,
    Murat

    Hi Murat,
    We recommend to use only 3 concurrent Instances at once, due to the fact, that excel can get unstable if the number of Excel instances is increased. This comes due to the design of excel. Excel shares global ressources on the system, and communicates itself with RPC to these ressouces. Sometimes these ressources are locked because they are already in use, then Excel waits for the release of the lock and comes into a dead lock situtation because it is not notified when the lock is released.
    Technically it is not avaoidable that some precalculations will fail in case massive load scenarios. This is more or less due to the office automation of excel.
    I hope this helps.
    Thanks,
    Michael

  • Frequenet dead locks in SQL Server 2008 R2 SP2

    Hi,
    We are experiencing frequent dead locks in our application. We are using MSSQL Server 2008 R2 SP2 version. When our application is configured for 5-6 app servers, this issue is occurring frequently.
    But, when the same application is used with the MSSQL Server 2008 R2 or SQL Server 2012, we don't see the dead lock issue. From the error lock and sql trace, the error message is thrown for the database table JobLock. We have a stored procedure to insert/update
    for the above table when the job moves from one service to other. The same procedure works fine when used with the 2008 R2 and SQL Server 2012 Version.
    Is the above issue related to the hotfix from the below url?
    http://support.microsoft.com/kb/2703275
    Following error message is seen frequently in the log file.

    If you are having deadlock trouble in your SQL Server instance, this recipe demonstrates how to make sure deadlocks are logged to the SQL ServerManagement Studio SQL log appropriately using
    the DBCC TRACEON, DBCC TRACEOFF, and DBCC TRACESTATUS commands. These functions enable, disable, and check the status of trace flags.
    To determine the cause of a deadlock, we need to know
    the resources involved and the types of locks acquired and requested. For this kind of information, SQL Server provides
    Trace Flag 1222 (this flag supersedes 1204, which was frequently used in earlier versions of SQL Server.)
    DBCCTRACEON(1222,
    -1);
    GO
    With this flag enabled, SQL Server will provide output in the form of a deadlock graph, showing the executing statements
    for each session, at the time of the deadlock; these are the statements that were blocked and so formed the conflict or cycle that led to the deadlock.
    Be aware that it is rarely possible to guarantee that deadlocks will never occur. Tuning for deadlocks
    primarily involves minimizing the likelihood of their occurrence. Most of the techniques for minimizing the occurrence of deadlocks are similar to the general techniques for minimizing blocking problems.

    I want TSPITR ,during this operation i faced this deadlock error.
    Before that we faced roll backsegment error for that we applied follwing workaround .
    If i applied follwing workaround before every backup and restore .i didn't get any error .all things went successful.
    spool /tmp/Createtest.log
    connect / as sysdba
    REM Perform startup in case we are still down
    ALTER SYSTEM SET PROCESSES=500 SCOPE=SPFILE;
    SHUT IMMEDIATE;
    STARTUP MOUNT EXCLUSIVE;
    ALTER DATABASE ARCHIVELOG;
    ARCHIVE LOG START;
    ALTER DATABASE OPEN;
    connECT / as sysdba;
    alter system set undo_management = MANUAL scope=spfile;
    shutdown immediate;
    startup;
    Connect / as sysdba;
    DROP TABLE TEST123;
    create table test123 (t1 number, t2 varchar2(10));
    begin
    for i in 1.. 300000 loop
    insert into test values (i,'AAAAAAAAAA');
    end loop;
    end;
    delete test123;
    commit;
    alter system set undo_management = auto scope=spfile;
    shutdown immediate ;
    startup ;
    The above workaround we applied before creating tablespace and datafile ,after that we face some dead lock error while restore TSPITR .Did you need any more information

  • XE Database Dead?

    Hello. I'm not very knowledgeable when it comes to DBA work, but I've hit a snag and would appreciate a little advice. I have an Oracle XE install on my home computer for keeping track of business receipts and such. Recently I couldn't connect to APEX and started looking into it. When I tried to connect with SQL+, I would get the message:
    ERROR:
    OR-01033: ORACLE initialization or shutdown in progress
    So I stopped and started the DB, checked to see the listener service was going, and still have the issue. I checked my alert_xe.log file, and it's... huge. Attached at the bottom, I included a fragment of my log file that consists of the last recent timestamp.
    I do have a script that runs on my computer that does an EXP every night on my schema, but if I try an IMP, I get the same message (which makes sense since my DB apparently isn't running).
    What would be your suggestions? I wanted some advice before I uninstalled and re-installed then imported my dmp backups.
    Thanks to any necromancers who can help me bring this back from the dead!
    Kerry.

    Rather think how you can assist an end-user with an XE database to make regular backups of his database in case of a problem. Be constructive instead of pointing a finger and go "+lesson must be learned+".
    What do you think he should be doing for backups? Run schema exports? If so, how does he backup APEX applications? DB exports? Rman? Run the database in archive log mode?
    Remember, that XE is fully an end-user environment. That is the market that Oracle choose to aim XE at.. and that is the market that our "solutions" offered here should be aimed at.Hi Billy
    As it's written in doc which Forstmann has suggested, it's possible to use RMAN in XE database. You're right, may be it's not so simple to make backups directly from RMAN utility, but it's possible:
    In Oracle Database XE, the database backup and recovery facility is based upon the Recovery Manager (RMAN) utility that is integrated into the database. Although there is an RMAN command line client similar to SQL Command Line, you do not need to interact with it directly to back up or restore your database. Oracle Database XE includes backup and restore scripts that you access using menu choices on your desktop. These scripts perform a full backup and restore of the entire database, and store backup files in the flash recovery area
    Just my 2 cents
    P.S.By google-ing I've found a blog post for backing up XE and APEX. Hope this article might be helpful for OP

    Your basic problem seems to be you have a trigger, which wants to use OLAP functionality, but OLAP is not installed or not available for whatever reason

    Thank you for your help

    I wrote this long time ago, have a read and see whether it can be soloved
    If a sad iPod icon or an exclamation point and folder icon appears on your iPod’s screen, or with sounds of clicking or HD whirring, it is usually the sign of a hard drive problem and you have the power to do something about it now. Your silver bullet of resolving your iPod issue – is to restore your iPod to factory settings.
    http://docs.info.apple.com/article.html?artnum=60983
    If you're having trouble, try these steps at different levels one at a time until the issue is resolved. These steps will often whip your iPod back into shape.
    Make sure you do all the following “TRYs”
    A. Try to wait 30 minutes while iPod is charging.
    B. Try another FireWire or USB through Dock Connector cable.
    C. Try another FireWire or USB port on your computer .
    D. Try to disconnect all devices from your computer's FireWire and USB ports.
    E. Try to download and install the latest version of iPod software and iTunes
    http://www.apple.com/itunes/download/
    For old and other versions of iPod updater for window you can get here
    http://www.ipodwizard.net/showthread.php?t=7369
    F. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
    http://www.apple.com/support/ipod/five_rs/
    G. Try to put the iPod into Disk Mode if it fails to appear on the desktop
    http://docs.info.apple.com/article.html?artnum=93651
    If none of these steps address the issue, you may need to go to Intermediate level listed below in logical order. Check from the top of the lists to see if that is what keeping iPod from appearing on your computer in order for doing the Restore.
    Intermediate Level
    A. Try to connect your iPod with another computer with the iPod updater pre-installed.
    B. Still can’t see your iPod, put it in Disk Mode and connect with a computer, instead of doing a Restore on iPod Updater. Go and format the iPod instead.
    For Mac computer
    1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
    2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
    3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
    4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
    5. Eject your iPod and do a Reset
    6. Open the iTunes 7 and click “Restore”
    For Window computer
    Go to folder “My Computer”
    Hope you can see your iPod there and right click on the iPod
    Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
    Now select “Format”
    Eject your iPod and do a Reset
    Open the iTunes 7 and click “Restore”
    In case you do not manage to do a “Format” on a window computer, try to use some 3rd party disk utility software, e.g.“HP USB Disk Storage Format Tool”.

    C. Windows users having trouble with their iPods should locate a Mac user. In many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
    Tips
    a. It does not matter whether the format is completed or not, the key is to erase (or partly) the corrupted firmware files on the Hard Drive of the iPod. After that, when the iPod re-connected with a computer, it will be recognized as an fresh external hard drive, it will show up on the iTunes 7.
    b. It is not a difficult issue for a Mac user to find a window base computer, for a PC user, if they can’t find any Mac user, they can go to a nearest Apple Shop for a favor.
    c. You may need to switch around the PC and Mac, try to do several attempts between “Format” and “Restore”

    Advance Level
    A. Diagnostic mode solution
    If you have tried trouble shooting your iPod to no avail after all the steps above, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod.
    You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. Toggle it on and off to be safe.
    Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
    iPod 1G to 3G: "Menu" and "Play/Pause"
    iPod 4G+ (includes Photo, Nano, Video, and Mini): "Menu" and "Select"
    The Apple logo will appear and you should feel the hard drive spinning up. Press and hold the following sequence of buttons:
    iPod 1G to 3G: "REW", "FFW" and "Select"
    iPod 4G+ (includes Photo, Nano, Video, and Mini): "Back" and "Select"
    You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode. For further details on Diagnostic mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/
    Try to do the 5in1, HDD R/W and HDD scan tests. Some successful cases have been reported after the running the few tests under the Diagnostic mode. In case it does not work in your case, and the scan tests reports show some errors then it proves your iPod has a hardware problem and it needs a repairing service.
    B. Format your iPod with a start disk
    I have not tried this solution myself, I heard that there were few successful cases that the users managed to get their iPod (you must put your iPod in disk mode before connecting with a computer) mounted by the computer, which was booted by a system startup disk. For Mac, you can use the Disk Utility (on the Tiger OS system disk), for PC user, you can use the window OS system disk. Try to find a way to reformat your iPod, again it does not matter which format (FAT32, NTFS or HFS+) you choose, the key is to erase the corrupted system files on the iPod. Then eject your iPod and do a Reset to switch out from Disk Mode. Reboot your computer at the normal way, connect your iPod back with it, open the iPod updater, and hopefully your iPod will appear there for the Restore.
    If none of these steps address the issue, your iPod may need to be repaired.
    Consider setting up a mail-in repair for your iPod http://depot.info.apple.com/ipod/
    Or visit your local Apple Retail Store http://www.apple.com/retail/
    In case your iPod is no longer covered by the warranty and you want to find a second repairing company, you can try iPodResQ or ifixit at your own risk
    http://www.ipodresq.com/index.php
    http://www.ifixit.com/
    Just in case that you are at the following situation
    Your iPod warranty is expired
    You don’t want to pay any service charges
    You are prepared to buy a new one
    You can’t accept the re-sell value of your broken iPod
    Rather than leave your iPod as paper-weight or throw it away.
    You can try the following, but again, only do it as your last resort and at your own risk.
    Warning !!!! – It may or may not manage to solve your problem, and with a risk that you may further damage your iPod, which end up as an expensive paper weight or you need to pay more higher repairing cost. Therefore, please re-consider again whether you want to try the next level
    Last Resort Level
    1. . Disconnecting the Hard Drive and battery inside the iPod – Warning !! Your iPod warranty will be waived once you open the iPod.
    In Hong Kong there are some electronic shops offering an iPod service for Sad iPod, the first thing they do is to open up the iPod’s case and disconnecting the battery and the Hard Drive from the main board of the iPod. Wait for 5-10 minutes and reconnecting them back. The reason behind which I can think of is to do a fully reset of a processor of the iPod. In case you want do it itself and you believe that you are good on fixing the electronics devices and have experience to deal with small bits of electronic parts, then you can read the following of how to open the iPod case for battery and HDD replacement (with Quicktimes)

    2.Press the reset button on the Hard Drive inside the iPod – Suggestion from Kill8joy
    http://discussions.apple.com/thread.jspa?messageID=2438774#2438774
    Have I tried these myself? No, I am afraid to do it myself as I am squeamish about tinkering inside electronic devices, I have few experiences that either I broke the parts (which are normally tiny or fragile) or failed to put the parts back to the main case. Therefore, I agree with suggestion to have it fixed by a Pro.

    Finally, I read a fair comments from dwb, regarding of slapping the back of the iPod multiple times
    Quote “This has been discussed numerous times as a 'fix'. It does work, at least for a while. In fact I remember using the same basic trick to revive Seagate and Quantam drives back in the mid to late 1980's. Why these tiny hard drives go bad I don't know - could be the actuator gets stuck in place or misaligned. Could be the platter gets stuck or the motor gets stuck. 'Stiction' was a problem for drives back in the 80's. Unfortunately the fix can cause damage to the platter so we temporarily fix one problem by creating another. But I know of two instances where a little slap onto the table revived the iPods and they are still worked a year or more later.”UnQuote

  • APEX error: Found dead shared server

    Hi,
    I frequently encounter an error when working with APEX. If I submit any change to APEX, fi a change on some page item, APEX asks me to whether I'd like to save the wwv_flow_accept URL. I then get a file save dialog. This doesn't happen all the time, but something like 2 out of 10 times I submit something.

    Hi,
    I took a bit of time to dig deeper into this issue. I came to the conclusion that there is a bug in Oracle XE:
    If you connect to Oracle XE database using the EPG path and if you create a report that gets its data over a database link, the shared server processes used to connect to the database break.
    What I did to produce this error:
    I installed Oracle XE Universal Edition on a Windows XP system
    I then updated APEX to the latest version 3.2
    At the database I simply created a database link pointing to the same schema the APEX-application is running at. I tested the database link.
    I then produced a simple test application with just one Report (I also tried a PPR-report with the same result) that displays orders with a query in line with this:
    <pre>
    select o.order_id, i.order_item_id, i.quantity, p.product_name, i.unit_price, i.unit_price * i.quantity amount
    from [email protected] o, [email protected] i, [email protected] p
    where o.order_id = i.order_id
    and i.product_id = p.product_id
    order by o.order_id, i.order_item_id
    </pre>
    When I ran this application, I was sometimes able to see the report without an error, sometimes a shared server process broke. You can watch the processes breaking by opening the admin/bdump directory and see how the database writes trace files for the shared server processes.
    Interesting to see is that the error happens not only when you try to see the report. If you hit the edit page link while running the page or if you submit the page definition with the link query in it, the same is likely to happen. You can see this error happening when APEX offers you to download the call to wwv_flow or the f-procedure. The contents of this download then is:
    <pre>IBMPC/WIN_NT-8.1.0</pre>
    with some binary information in front of the message.
    Another bug I'd like to add came up when I was lucky to see the report with the PPR-template. I tried pagination but this wouldn't work. Looking into this, I found the following link:
    <pre>
    javascript:html_PPR_Report_Page(this,'R2060428410112776','javascript:$a_report('2060428410112776','16','15','15');')
    </pre>
    To my understanding this can't work at all if you look a the apostrophes. So how to proceed with this???
    This to me is a severe problem, as I wanted to utilize APEX as a frontend for a production database to report the contents. I was informed by Varad that a way around this is to use an Apache access to Oracle XE but as far as I'm informed, this forces me into a licenced version in order to be able to run mod_plsql.
    I read about the mod_owa-approach, but the programmers state that this is not compatible with APEX. So my question is: Do you have any suggestion on how to proceed with this?
    Thanks,
    Jürgen
