checklist - basis cutover in prep for going live

SAP Planning: Best Practices in Implementation Checklist – Cutover & Going Live

Basis Cutover – Background Information

Leverage this checklist to cutover from the S15 (Staging) to the P20 (Production) system. At a high level the procedure involves a homogeneous system copy geared to ensure that all data (both development/master and customizing) are transferred to the production environment. It is assumed here that both Staging and Production are clustered in a W2KAS environment, running MSCS and Oracle Failsafe. Oracle 8.1.7 is assumed as well, with an SAP Basis release of 4.6C.

Note that this cutover process requires data/configuration clean up after the system has been copied. At a high level, the process unfolds as follows:

Prepare the S15 database for export

Export the S15 database

Import the P20 database from the exported files

Clean up the P20 system after the data has been imported

Copy the original S15-151 client to P20-020

Create the users in the P20-020 system

Setup DBA and functional jobs.

Proactive maintenance steps

Check for any errors and open to core team members

Prepare the S15 database for export (2 hours)

1. Post a system message on S15 using /nSM02, detailing the outage required for database export.

2. Delete all pending or cancelled update requests using transaction SM13.

3. Execute transaction SE16, view table contents of VBDATA, and verify that all updates were successfully deleted.

4. Delete cancelled and finished background jobs using transaction SM37.

5. Check TEMSE consistency and delete inconsistent objects using transaction SP12.

6. Execute any special jobs related to data dependencies.


Export the S15 database (3 hours)

7. Login to the S15 instance as S15ADM.

8. Using the cluster administrator, move all groups to S15 Database Server (Node A) for execution. Wait until all groups and resources are back online before continuing to the next step.

9. Using the cluster administrator, take the “SAP R/3 S15” resource offline. This does not include the disk or network resources within the “SAP-R/3 S15” group. Wait until the “SAP R/3 S15” resource status changes to offline.

10. If any application servers are running in S15, these should be shutdown for the full duration of the export.

11. Copy the file “DBEXPORT.R3S.ORIG” to “DBEXPORT.R3S”. These files are located in the “C:\users\S15adm\install” directory. If the “DBEXPORT.R3S.ORIG” does not exist, it must be copied from the SAP R/3 KERNEL CD for release 4.6C SR2.

12. Execute the program R3SETUP.EXE from the “C:\users\S15adm\install” directory.

13. Select the DBEXPORT.R3S file to be used as the input parameter file.

14. The following parameters should be specified when prompted:

Parameter Value

SAP System Name S15

Instance Number 15

Directory for SAP System I:

Domain US_SAP

Name of Central Instance Host S15cidb

Database system name S15

Character Set WE8DEC

Name of Oracle home S15817

Installation Style Old Style

Operating System for target I386

Database of target Oracle

Directory for export files O:\Export

Update statistics Quick and Estimated

Split STR and EXT files for R3LOAD NO

Number of parallel processes 8 (assumes 8-CPU DB server)

Maximum size of export files 2000


15. The database will now be exported. The anticipated run time is 2 hours from start to finish. Errors and warning can be viewed using the R3SETUP log window. The Windows task manager can be used to view activity on the system to ensure processes are still running.

16. When the export is completed, move the CLUSTER and SAP-R3 S15 group to S15 CI node (cluster node B) for execution.

17. Bring all groups online and verify that all resources are online.

18. Login to the S15 system using SAPLOGIN from any desktop computer and verify that system accordingly.

Import the P20 database from the exported files (6 hours)

19. Login to the P20CI system as P20ADM.

20. Using the cluster administrator, move all groups to P20 CI for execution. Wait until all groups and resources are back online before continuing to the next step.

21. Using the cluster administrator, take the “SAP R/3 P20” resource offline. This does not include the disk or network resources within the “SAP-R/3 P20” group. Wait until the “SAP R/3 P20” resource status changes to offline.

22. Using the cluster administrator, take the “OracleP20817TNSListenerFslP20ora” and “P20.WORLD” resources offline. This does not include the disk or network resources within the “OracleP20” group. Wait until both resource status changes to offline.

23. Copy the file “DATABASE.R3S.ORIG” to “DATABASE.R3S”. These files are located in the “I:\users\P20adm\install” directory. If the “DATABASE.R3S.ORIG” does not exist, it must be copied from the SAP R/3 KERNEL CD for release 4.6C SR2.

24. Modify the “DATABASE.R3S” file so that the STEP section between 200 and 300 looks as follows: (any additional steps should be removed)

190=R3DBSAPENVIRONMENT_NT_IND

200=R3DBUSERENVIRONMENT_NT_IND

230=DBINITORACREATE_NT_ORA

240=DBINITORAMODIFY_NT_ORA

250=DBLISTENERSTOP_NT_ORA

290=DBLISTENERSTART_NT_ORA

300=DBCONVTPLFILES_IND_ORA

25. Delete the following directories (including sub-directories)

i. J:\Oracle

ii. K:\Oracle

iii. L:\Oracle


iv. M:\Oracle

v. N:\Oracle

26. Start the following services (NOT from the W2KAS Cluster Administrator)

i. OracleServiceP20

ii. OracleP20817TNSListenerFslP20ora

27. Update the local host file, add the following entries:

179.165.221.12 P20cidb

179.165.221.11 P20ora

179.165.221.10 P20cluster

28. Map the network drive Y: to \\S15cidb\O$\Export.

29. Browse to the \DB\ORA directory and open the file DBSIZE.TPL (Backup original file first!)

30. Update the file DBSIZE.TPL as follows:
