Renaming/log rotation of opmn default island application logs

Hi, I wonder if someone has already figured this out.
We are running 10.1.2 OAS and we would like to control the rotation of our instance applicaiton logs. Currently in $J2EE_HOME/opmn/logs we have files named "OC4J~<container name>~default_island~1" and we have to stop the OC4J container to control these. Placement and naming would be nice, but rotation is the most important.
Is there any way of adding something to opmn.conf to do this? Perhaps like the log-file tag that is used by the ipm.log e.g
<log-file path="$ORACLE_HOME\opmn\logs\ons.log" level="6" rotation-size="10000" rotation-hour="00"/>?
Regards, Aidan

for OPMN logs you can add this to the log part
<log-file path="/u09/app/oracle/product/ias903/opmn/logs/ipm.log" level="3" rotation-size="1024"/>
when it get 1024 kbits it will rotate.
THis apply for 902 and 904 OAS
Im not sure this work for 10.x.x
And I dont know a way to delete this files, but for sure you can create a script with cron who deletes the oldest ones.
Hope this Helps.
Regards

Dear all,
I need your inputs to solve the below mentioned issue,
There is a communication developed between MS sharepoint and SAP.
By using Mapper Classes for each and every operations the conversion of data format from Sharepoint to SAP and viceversa happens.
We can see the message or error logs created during the conversion process using the T-code /iwfnd/view_log.
But i want my custumized messages has to come in that log for that i used the following code in the mapper class Post method but still my logs are not coming in the T-code /iwfnd/view_log.

Hi Girimurugan,
I am currently working with SAP Gateway related stuffs and I need a clarification regarding the application log.
Hope you are very busy and please clarify the doubts if you can spare few minutes towards this query.
Appreciate your valuable advise towards this.
Query:
Can we log any of the different types of logs (I Info / W Warning / A Abort or Cancel / E Error ) into Application Log(/IWFND/APPS_LOG) of the Gateway system in a Hub deployment model ?
How the logging can be achieved?
What are the scenarios, wherein the Application logs are preferred?
Also I have already raised a query in the SCN with this link: http://scn.sap.com/message/15477543. But could not get much details about it.
Can you please clarify the same?
Thanks & Regards,
Mohamed Meeran

How to create application log in SAP

According to my reqirement,I need to display messages in the application log whenever some updation is done.
How to do create application log and display messages in the application log.

Hello Smriti
If you have interface IF_RECA_MESSAGE_LIST available on your system then I highly recommend to use as message collector.
When you create an instance of the interface (CF_RECA_MESSAGE_LIST=>CREATE) you can provide an application log object.
The collected messages can easily be saved as log.
For an example have a look at my Wiki posting [Message Handling - Finding the Needle in the Haystack|https://wiki.sdn.sap.com/wiki/display/profile/2007/07/09/MessageHandling-FindingtheNeedleintheHaystack]

LMS3.2 Log rotation problem

Hi,
we use LMS3.2 (windows single-server) for ~4500 devices and have a problem with log rotation.
That's our configured log roation:
Name with location
Size (kb)
Format
No.of Backups
1.
D:\CSCOpx\log\dcrclient.log
102400
gz
3
2.
D:\CSCOpx\log\ICServer.log
102400
gz
3
3.
D:\CSCOpx\log\syslog.log
1024000
gz
5
The backup directory is the same as the usual log directory. The size of the 3 files is already bigger than the configured size in log roation, see:
dcrclient.log     2,1 GB
ICServer.log     1,1 GB
syslog.log        9,7 GB
After the log roation configuration we restarted the daemon manager, but it's not working. There are no backup files created and the 3 files are still growing.
Regards
Hendrik

After you configure the log rotation you need and restart the daemons, you need to schedule the job. The schedule buttong is available under
Common Services -> Server -> Admin -> Log Rotation.

Transaction for application log

Using IDOCS. One has errored but cannot get into application log as pop up not appearing (memory issue or something) for me to double click the log number and go into the application log to view it. Does anyone know the transaction or menu path to access the application log direct so I can see what the error is about?
Many thanks
Larissa

Hi,
USE SLG1 Transaction.
Thanks,
Naga

Error/Application Logs

I have a scenario in which I have to display error logs when exception occurs.
There is a transaction SLG1 where you can see all the application log for a particular process. Has anyone worked on calling these types of transactions to display error or application logs. If so, please throw some light on this.
Thanks a lot
Deno

Hi Deno,
If you want to see the error message in SLG1. Follow the following steps:
1. Use the FM BAL_LOG_CREATE to create the application log.
2. Use the FM BAL_LOG_MSG_ADD to add the message to the application log.
3. Save the application log using FM BAL_DB_SAVE.
Now you can see your error message in the SLG1 transaction.

Can I rotate application log in OC4J_Portal_default_island_1?

My application.log file in %oracle_home%\j2ee\oc4j_portal\application-deployments\portal\oc4j_portal_default_island_1 grows quickly. Can I configure it to rotate every day or when it reaches a certain size? If yes, how?
TIA
Edited by: Angrydot on Aug 25, 2008 9:51 PM - what happens if I edit an old post in the new forum?
Edited by: Angrydot on Aug 25, 2008 9:52 PM - nothing

To rotate the OC4J log files under $ORACLE_HOME/opmn/logs, there are few parameters you can modify that are not documented in Oracle 9.0.4/10.1.2 documentation.
[New JVM parameters]
"stdstream.filesize"
Max file size limit of each archive. Unit is megabyte.
"stdstream.filenumber"
Max number of files that oc4j can keep as archives. The oldest file will be automatically deleted if the limit is exceeded.
[Usage]
ex 1: rotate stdout/stderr when the file size is reached to 2.5M byte.
java -Dstdstream.filesize=2.5 -jar oc4j.jar -out std.out -err std.err
OraHome\opmn\conf\opmn.xml
In order to get these parameters in opmn.xml you need to define it as follows:
<category id="start-parameters">
<data id="java-options" value="-server -Djava.security.policy=$ORACLE_HOME/j2ee/home/config/java2.policy -Djava.awt.headless =true -Dstdstream.filesize=0.2 -Dstdstream.filenumber=5"/>
<data id="oc4j-options" value="-out std.out -err std.err"/>
</category>
The new log files will be created under:$ORACLE_HOME\j2ee\home\home_default_island_1\
The file naming will be like:
std_2006_02_22_14_01_17.out
std_2006_02_22_14_16_25.out
Important notes:
1. Backup opmn.xml file before any modification.
2. Modify opmn.xml file to specify stdstream.filesize and stdstream.filenumber. See the example above.
3. Test and validate this solution in your test system first before implementing in Production.

Rotating the default-web-access.log log

Can the default-web-access.log file be rotated with ODL?

Yes, at least since on 10g Release 2 (10.1.2) , see the <odl-access-log> secction on:
Oracle® Application Server Containers for J2EE User's Guide
10g Release 2 (10.1.2) - 3 Advanced Configuration and Development

OPMN system.out and system.err log rotation?

I would like to rotate the log generated by OPMN by default for system.out & system.err, which is named:
OC4J~APPNAME~home~default_island~1
I see the entries in the opmn.xml file for the ons.log and ipm.log which ARE being rotated properly. I've read that you can redefine the log file for system.out and system.err, but can't find any about rotating these logs.
Does anyone have any info about this topic?

If anyone's curious and is trying to do this themselves, I eventually asked Oracle, who stated it could not be done.

OPMN Log rotation 10.1.2

How to rotate the OPMN logs in the 10.1.2 environment
Here is my environment
Oracle Application Server: 10.1.2
Sun Soalris 10
Infrastructure has the following
%ORACLE_HOME/opmn/logs
dcm-daemon~dcm-daemon~dcm~1
HTTP_Server~1
ipm.log
OC4J~OC4J_SECURITY~default_island~1
OID
OID~1
OIDCTL.log
ons.log
opmn.log
Any document which gives step by step implementation of log rotation by size and time
Is ODL is supported for OPMN log rotation? if then how to do it ?

The document looking like to rotate the ons.log ipm.log using the configuration change in the opmn.xml file as the
<log-file path="path" level="level" rotation-size="kBytes" rotation-hour="HOD"/>
Here are my questions
1. How can give the rotation-hour (is it timestamp value like 200808020830 yeardaymonthhoursminutes )
2. Is it going to change the file name like ons200808020830.log ipm200808020830.log , if yes a) ons.log ipm.log files will exist inclusing the above files or not
3. what about the other log files rotation in the opmn/log directory like (in my previous posting)
dcm-daemon~dcm-daemon~dcm~1
HTTP_Server~1
ipm.log
OC4J~OC4J_SECURITY~default_island~1
OID~1
OIDCTL.log
Could you please answer my questions and also give me some sugestion to implement OPMN log rotation.

How to setup rotation for application.log?

In order to get the Portal Performance Statistics running, we need to retrieve the page views from file application.log in directory <ORAHOME>\j2ee\OC4J_Portal\application-deployments\portal\OC4J_Portal_default_island_1.
This file continues to grow and therefore we want to set up rotation, in order to get one file per day.
We are following note 264373.1 and have read all documents and manuals about logging, but can not figure out how to manage this.
Can anyone help us? We are working with 9.0.4.1.
For Oracle employees: see also tar 4193327.994.

I can't speak for how portal uses the log file, but in general, the way you do it for a deployed J2EE application on OC4J is as follows.
Deploy the application EAR file. Lets say the app is called Test.
In the j2ee/home/application-deployments/Test directory, a file will be created called orion-application.xml.
If you look in this file, you will see an entry which looks like
<log>
<file path="application.log" />
</log>
This defines the log file for this application.
Now if you want to setup log file rotation for this app, edit the orion-application.xml file and firstly, comment out the above.
Note: you can leave the log tag in if you wish, but you'll get double log messages. Remove it if you do this in production and are trying to conserve space ;-).
Then add in the below to setup ODL based logging for this application:
<log>
<odl path="logdir"
max-file-size="1000" max-directory-size="10000" />
</log>
What this does it to tell OC4J to output the log messages using it's ODL format model, to create a directory called logdir (in the current directory) and then to start writing to log files called log.xml in that directory.
The max file size of log.xml is 1000KB, and the max directory size of the new logdir directory will be 10MB.
The ODL logging system will manage the log files in this directory according to these constraints -- when a log file gets bigger than max-file-size it gets archived as logN.xml. When the overall directory size gets bigger than the max-directory-size specified, the oldest log file from the list is removed so that the max directory size is honoured.
I don't think we can specify a rollover period (ie one day) with ODL. I'm pretty sure it's just file size based only.
I think the above should apply to Portal since it runs on OC4J. In which case, you'd change the orion-application.zml in the <ORAHOME>\j2ee\OC4J_Portal\application-deployments\portal directory instead of j2ee/home/application-deployments/<app-name>.
However, I can't speak officially for Portal since I don't work with that product. From a pure OC4J perspective the above holds true and works.
cheers

OC4J- Default Island in Oracle application forms reports services

Hi,
Please can any one answer this question.
How many cun current sessions will support in OC4J default island in oracle forms & reports services?

Yes, by using SSO you can achieve it. The partner applications should be registered with SSO.
Method will depend on your version of OAS for the two applications.
