Heterogenous system build

Hi Experts,

We have an upgrade coming up and for the same have to create sandbox systems for CRM (ABAP, Linux, Oracle), BW (ABAP+Java, Linux, Oracle) and EP (Java, Windows, MS SQL) from the production systems.

All our systems are on VMWare. We have high availability setup but only on the VM level, not on SAP level. The sandbox systems will be copied over as clones from the production systems. I have below two queries -

1. Can I use the system rename tool? I have checked all the prerequisites and we qualify all of that, except the HA. I am not sure this HA restriction (according to note 1619720) will apply in this case also where HA is only at the VM level.

2. If I don't or can't use the system rename tool, how can I change the systems. There will be a DB<sid> and SAP<sid> change. I know the post steps (running BDLS etc), but not sure how to change the SIDs of the system.

Thanks for your help in advance.

Regards,

Neha Bhardwaj

    Hello Neha,

    The HA being addressed at the SAP note 1619720 is when SAP itself is installed at an HA environment (cluster).

    If the HA is at the VM level (by this I believe you mean that VMware will move the VM through different physical servers as needed), then you can consider that SAP is not under HA scenario for the purposes of the rename tool (in fact, SAP itself is not at HA 😉, it is the VM that is).

    Thus, I believe it should be OK to use the rename tool.

      Thanks a lot for your reply Isaias. One more question, when the cloning is performed (in Unix), would the system rename tool be able to rename the mounts /oracle/<source SID>/sapdata<n> etc to <target SID>.

      If not, what is the resolution?

      Thanks,

      Neha
