BASIS check after H/W, OS & DB upgrade

[Former Member]

Hi

At present we are on R/3 46C,Oracle 8i, HP UX 11i.

Our exisiting H/W, OS and DB is being upgraded to meet the demand for future ECC upgrade. This upgrade is done by a seperate vendor.

Present:

SAP　 KERNEL 4.6D　64-BIT

DB　　　ORACLE　8.1.7

OS　　　HPUX　 11.11/PA-RISC

After the H/W,OS & DB upgrade, the configuration will be as below,

Future:

SAP　　 KERNEL 4.6D　64-BIT

DB　　　ORACLE　9.2　64-BIT

OS　　　HPUX　　11.23/IA64 64BIT

After the successful upgrade, what are key checks that we have to perform from BASIS side to ensure that everything works fine before releasing the system to end users..

Pls drop your valuable thoughts on this regard.

regards,

Vinodh.

First check the all the versions, patch levels are showing correct or not.

Second run the golden t-codes, ie. all basic t-codes.

It is from sap level as well as os level also.

Hi Vinodh,

1. set the parameters in RZ10.

2. check for the RFC connections(sm58)

3. logical clients

4. check for STMS routes correctly.

hope this helps you.

Hi,

1. Have an Early Watch report created.

2. Required changes may be Oracle parameters, check for notes. Early Watch report will also give hints on this.

3. Do DB Checks, Update Statistcis and DB tools at OS level.

Thanks
