'Homogeneous system copy' in a few minutes ?

[Former Member]

Hi,

I have seen on DSAG congress how an Administrator has done a technical Homogeneous system copy for refreshing a QA System, in 7 minutes. (And the new SAP System was running). Without reworking in the running SAP-System.

This is done in a WIN/Oracle environment wit NETApp Storage with the function SNAP from netapp.

I want to ask if there is a possibility, to speed up the homogeneous system copy on iSeries?

Normally you need hours for deleting the library. You need hours for restoring data. And some time for SAPInst.

kind regrads,

Hi Carsten,

this is definetely NOT possible on iSeries. It can only be done on a platform wit snapshot technology, that can be mounted on a different system. If the SID or the hostname changes, there ARE suggested post steps - most of them are not needed for pure ABAP systems, but at least would be useful.

As you know, i5 uses the disks "AS ONE" and therefore cannot create snapshots & mount them on another partition. I know, that external storage systems are able to create snapshots on i5 as well, but they are "just" used for backup and NOT for mounting on a different system.

In my eyes, the only option to achieve this would be an iASP environment, that becomes detached and then run different. But, if you want to rename the SID, you need at least a lot more time than 7 minutes as you have to stop journaling, rename the lib and then start journaling. It would be a significant time improvement for the copy - but for a pretty high price in my eyes ...
