Odd System Copy

49 Views

Hello Experts,

I am performing a homogeneous system copy on linux w/ MaxDB. The source system is really more like source systems. Using one database instance (XDB), I have an ERP 6.0 EHP4 system (XS1) and an EP instance (JS1). My first step was to export the database using the Database Manager; then I made the export available to the target system. The system copy for the abap application server went without a problem. Now I am having trouble with the J2EE system copy.

My assumption was that the single MaxDB export contained both the ABAP schema (SAPXS1) and the J2EE schema (SAPJS1DB). Also, I assumed since XS1 and JS1 are two separate instances sharing a single database instance, then I would also need to complete two system copies. Were any of those two assumptions false?

My hope was to skip the recovery w/ initialization step during the J2EE system copy since the DB containing the J2EE backup should already be loaded in the target database host. The error I'm encountering on the J2EE system copy is "You can not use existing instance while installing with backup/recovery method." Sadly, that error message is very straight forward and doesn't leave much hope to complete both system copies using this method.

A system copy for both ABAP and J2EE stacks ins't the correct path, is it?

Any help is appreciated.

Kind Regards,

Zach Shay
