Disaster Recovery, How to keep SAP software updated in DR

[Former Member]

Hi ,

We're planning to setup a Dr site with a SAP server that has the same software as in the production site. Question is how do we keep the SAP software to be the same as in production ? As sometime we may apply updates.

Will 'rsync' works in this case ?

Our OS are AIX 6.1, running SAP ECC 6.0

Thanks.

rsync is a good option, however, you can't use that to distribute database updates.

Haii...

from your question i am understanding that u r going to setup a new DR, as you said your are using OS AIX SAP ECC6,

what about the Database u are using, Oracle ?

Activities that you have to carried out at both the places i.e. DC & DR.

1) OS Patches

2) OS Kernel & SAP Kernel

3) DBA activities

4) Applying SAP License

Activities that you have to carried out at DC Only

1) SAP Patch Management

Daily activities that you have to perform either by manually or automatically

1) Applying archive logs from DC to DR

Note :

Testing of DR is must after implementation

Geographical location of DC & DR Should be different

Hi,

I am not aware about AIX.

Our OS is linux and we use EMC storage.Our storage guys used srdf link so whenever any update happens to the promary disk it gets replicated to the DR site as well.

Hi

EMC timefinder/SRDF should be find just need to be sure the DB is consitent when BCVs are split

If you go rsync way you can use it for interaces and transports /usr/sap and /sapmnt

#rsync -az -e ssh --delete source-server:/usr/sap/ file-system-path-DR-env

u2013a ensures all file attributes are retained

-z compress the file stream

-e ssh use SSH encapsulation

--delete delete files on DR if deleted on prod.

Dataguard in Maximum Performance Mode for DBs (async) SAP Note : 105047

Need to keep it all in sync (flat files-rsync ,code -backups or manual and dbs - ora Dataguard)

Hi Chris,

For the code-backups, which path or item you're referring to ?

Hi Chris,

We never had problems with the EMC disks till now.We have used storage replication even to update the database binaries which means we never patch the DR since we have patched the primary it gets replicated to the DR.Thanks.

Hi,

If you upgrade kernel or upgrade database etc. that thing you have to do it manually on your DR site.

Thanks
