upgrade to enhp1 for a BI with a standalone JAVA

[Former Member]

Dear SAPers:

We plan to upgrade to ehp1 for a BI with a standalone Java which is on a different server with a different SID.

During the upgrade , the BI might be shutdown several time (e.g. we want a milestone backup, etc.):

1) if before we shutdown BI , Java is NOT shutdown, whether it will cause any problem?

2) can we keep the Java system down before the entire upgrade until the upgrade is done?

3) This is actually a quesion about whether BI and its standalone Java can be shutdown and started seperately no matter

its countpart is up or down.

4) Another question is that when start/stop both SIDs, the sequence maters?

We only dealed with ABAP+JAVA before. This is my first time to handle a standalone Java which is an out-sourcing system to us.

Could you please share you experience?

Thanks!

Hello Jessica,

1) if before we shutdown BI , Java is NOT shutdown, whether it will cause any problem?

- If BI ABAP is the UME data source for Java, then Java engine will be down automatically when the backend BI is down.

2) can we keep the Java system down before the entire upgrade until the upgrade is done?

- In this case, yes.

3) This is actually a quesion about whether BI and its standalone Java can be shutdown and started seperately no matter

its countpart is up or down.

- As I explained in point#1, Java should be down when you are planning to shutdown BI, if BI is the UME data source for Java.

4) Another question is that when start/stop both SIDs, the sequence maters?

- In this case, yes. First Java and then BI.

Hope your question is answered.

Thanks,

Hi Jessica,

I guess that your BI ABAP system is the UME for the BI Java system.

1. If you shutdown BI-ABAP, user authentications for BI-Java will not work.

2. You should keep the Java system down.

3. BI-Java will not startup until you start the BI-ABAP

4. Stop Sequence : BI-Java -> BI-ABAP

Start Sequence : BI-ABAP -> BI-Java

Thanks.
