After Restoring/Backup of File System XI Java Instances are not up!

[Former Member]

Hello all,

We are facing problem in restoring the SAP XI System, after taking backup of the system the <b>java instances</b> in SAP XI System are not starting again. ABAP connections are fine.

Can anyone provide suggestions/solutions in order to restore the XI System back.

The system information is as follows.

System Component: SAP NetWeaver 2004s, <b>PI 7.0</b>

Operating System: SunOS 5.9, SunOS 5.10

Database: ORACLE 9.2.0.

Regards,

Ketan Patel

Are you really running a <b>WebAS 7.00 against an Oracle 9 database?</b> This is not supported...

Check why the system is not coming up:

cd /usr/sap/<SID>/DVEBMGS<sysno>/work

check dev_boostrap

dev_jcontrol

std_server0.out

Hi

<i>>>>Are you really running a WebAS 7.00 against an Oracle 9 database? This is not supported...</i>

are you sure that is not compatible?

Because till the last day before the backup, XI system was up and running

If it´s REALLY a PI 7.0 (SAP_BASIS 700 and WebAS Java 7.00) then it´s not compatible. WebAS 7.00 needs Oracle 10g (http://service.sap.com/pam)

Also see

--> Availibility

--> SAP NetWeaver 7.0 (2004s) PAM

If you open the Powerpoint, you will see that Oracle 9 is not listed. I wonder, how you got that installed.

Neverless, if you recover a Java instance, both filesystem and database content (of the Java schema) must be in sync, means, you need to restore both, database (schema) and filesystem, that have been backed up at the same time.

Check Java Backup and Restore :

Restoring the System

1. Shut down the system.

2. Install a new AS Java system using SAPInst, or restore the file system from the offline backups that you created.

3. Import the database backup using the relevant tools provided by the database vendor.

4. Overwrite the SAP system directory /usr/sap/.

5. Start the system (see Starting and Stopping SAP NetWeaver ABAP and Java.)

The J2EE Engine is restored with the last backup.

Dear Markus,

Thanx for your reply.

I would coorect some information.

Oracle version is 10.2.0

I would also like to reframe my problem.

XI server(both abap and Web) was working fine. Each weekend we take full backup(file system+DB)(UFS) of server. After taking backup server got up and we were able to login through abap but java web page was not openning. We did some troubleshooting it didn't work and finaly we restored the backup and somehow it worked. Next week after backup again same problem arose. We again restored latest backup but this time problem still exists.

Regards,

Ketan

What are the last lines of dev_server0, std_server0.out and dev_jcontrol if the startup of J2EE fails?

Hi Markus,

I checked these files changed date and time. It was prior to the backup date. These were not updated even after backup and restore process.

What about the other trace files with

std_`? Check those too (std_bootstrap. etc)

Is your JAVA_HOME set for the user starting the instance?
