Current day to day life, Basis administrator faces lot many issues which requires administrator to provide a system which works in same environment but still not performing any interface activities with other systems available in your business envionment. In our term, We so call it as “SYSTEM ISOLATION”.

Consider below scenerios

1. System is crashed and need to restore the system from backup copy.

2. Need to prepare an testing environment from the backup copy of Production system.

3. Administrator want to perform an root-cause-analysis on the system which is not fit for operation.

Check list which Basis administrator need to consider to perform while bringing up system in Isolated mode.

1. No background workprocess by changing profile parameters (Instance profile) (OS Activity)
2. Unmount the interface folder (OS Activity)
3. Lock communication user in local system (SU10)
4. Change RFC connection to disabled outgoing communication (mask hostname in SM59)
5. Change Direct database connections definated at application level (DBCO)
6. Change repository connection (mask hostname) (OAC0)
7. Remove / disconnect the resigter program in SMGW
8. Remove server from load balancing (SMLG)
9. Remove RFC Load balancing (RZ12)
10. Stop the channels in PI system which send messages to isolated system
11. Stop batch job scheduler or suspend the release jobs
12. Deregister the outbound queues (SMQS)
13. Deregister the inbound queues (SMQR)
14. Lock the printers (SPAD)
15. Change mail and FAX configuration to ensure no communcation goes outside (SCOT)
16. Mask the file path for IDOC processing (WE20 / WE21)
17. Mask the exchange server configuration settings (local system) (SCOT)

Once above steps are followed, it ensures that your system is working fine in isolated mode !!

Once system up and running fine in isolation mode, administrator starts releasing functionalities one by one.

Note: Order of performing isolation and releasing system completely depends on the kind of system interface you have in your environment. Steps which derives above is totally based on configuration/interface used in the system and it may not contains all the steps !!
