if your system is not a dual stack system, only ABAP can be upgraded.

if you have JAVA stack on another SID, you will need to install this option in a second step.

Hi Eric Brunelle

Thanks for Reply.. we are trying to install dual stack. in EPH1 X64. On central system

i am not getting that option to select the java and Abap. Can you please suggest the way of installing the ABAP and Java stack for BI system.

Thanks

What installation media do you use?

It's not advised (any more) to install dual stack instances for various reasons. Especially in the BI case one should put the Java part on a second server/machine to avoid any performance issues and to make maintenance easier:

- a double stack instance always implies a combined update in case of service packs and release upgrades

- system copies must be done using sapinst, a database backup/restore only won't work

- performance tuning can be cumbersome because you can't control CPU or memory usage despite how much memory and/or CPU power you have

Raj,

some people beleive their system ids a dual-stack, but their ABAP and JAVA istances are using different SIDs on the same server. if this is the case, then it it not a dual stack system.

There is no real need to install a dual stack system any more. If you check the link I gave you it's especially in the BI case recommended to use two separate instances and not run a dual stack.

Looks good.

And what path do you select in sapinst?

Be aware of the fact:

- only Unicode supported for ABAP + Java instance

- only 64bit

HI Markus,

Yes i am selecting UNcode also.

What you need to do is:

- install the ABAP instance

- install the Java Addin with usage type BI-Java

Again - I (and SAP) HIGHLY recommend installing two separate instances and not combining the two.
