Restoring Enterprise Portal 7.01 to pre-patched state

[Former Member]

Hi SAP Gurus,

We are preparing to patch our Enterprise Portal to a higher support package stack, however we would like to confirm on the contingencies in the event of a failure and a need to restore Portal back to it's original pre-patched state.

Currently we plan to do offline backup on the Database of the portal before running the patches in JSPM. Is it sufficient to just backup the DB? Do I also need to the backup of the OS binaries in the /usr/sap/<SID> directories and the SYS directories?

Thanks in advance.

ps: pls don't ask us to "check with our basis guy". If we could we wouldn't have post this.

Regards,

Jansen

Hi Jansen,

You need to preform a database backup along with the filesystem backup as some of the binaries are kept on OS /usr/sap/SID

File system

For successful system recovery, the backup of the following files and folders is required:

·        The global share directory (<sapmnt>/<SID>). For more information, see the relevant installation guide on SAP Service Marketplace at http://service.sap.com/instguides.

As part of this backup, you must have the <sapmnt>/<SID>/SYS folder.

·        The bootstrap.properties file, which is located in the following directories:

¡        On Windows platforms, in <drive>:\usr\sap\<SID>\JC<instance_number>\j2ee\cluster\bootstrap.

¡        On Unix platforms, in /usr/sap/<SAPSID>/DVEBMGS<instance_number>/j2ee/cluster/bootstrap.

To ensure that no changes are made to the file system during backup, stop the Software Deployment Manager (SDM).

·        The instance.properties file, which is located in the following folder:

¡        On Windows platforms, in <drive>:\usr\sap\<SID>\JC<instance_number>\j2ee\cluster.

¡        On Unix platforms, in /usr/sap/<SAPSID>/DVEBMGS<instance_number>/j2ee/cluster.

Hello

Check these links:

AS Java stores data at the OS level /usr/sap/SID file system and also at the Database level.

If the Java system has custom portal images then they are stored at the OS level.

You need to backup the kernel only if you are doing a kernel update else there is no need.

The above links will provide you the information as to what you need to do for J2EE patching.

Good Luck
