We are going to deploy the ESS/MSS function on a newly installed ERP2005 instance. However, I realized that our installation team might not install it correctly--- Here's the current scenario:
two physical servers are involved,
ECC6.0 server installed with Usage type ECC, AS ABAP and AS JAVA (so there is a java stack on ECC server);
EP7 server installed with Usage type EP, AS JAVA;
I notice that they forgot to install usage type XSS during either one of the installation.
My questions are:
1. Is it ok to go back to SAPINST to reselct XSS so it can be got installed
2. Where is the best place to put the XSS UT? I noticed that if the XSS is checked, UT EP is required and will come alone with it. So is it a good idea to put XSS on the same server as ECC/ABAP? I also heard that if they are on the same server the performance will be better as the java stack and the ABAP stack are on the same box, so no network traffic.
