It is always asked whether it is necessary to stop/restart SAP ABAP system to do system maintenance operations. The following is the summary

of some scenarios for your reference:

1. kernel update

   It is necessary to shut down SAP system before kernel update.

2. change request transport

   It is necessary to log on ABAP system and use T-code : STMS to

transport change request between systems, so there is no need to shut

down SAP system. but it is better for you to prevent any other operation

running during request transport. Changes are activated automatically

during import, so you do not need to restart target system after

transport.

3. SAP note implementation

   SAP notes are implemented via T-code : SNOTE on sap system, so

there is no need to shut down SAP system. but it is better for you to

prevent any other dialog/background operation running during note

implementation. Changes are activated automatically during note

implementation, so you do not need to restart SAP system after note

implementation.

4. support package implementation/add-on installation

  You should log on client 000 and use T-code : SPAM/SAINT to

implement support packages or install add-ons, so there is no need to

shut down SAP system. But you should make sure that no any other

operation is running during support package implementation/add-on

installation. You do not need to restart SAP system after support

package implementation/add-on installation, but it is suggested to run

T-code:SGEN to generate ABAP program loads.

5. system upgrade

You do not need to stop SAP system manually during system upgrade.

The upgrade tool permits users to do normal operations before reaching

downtime phase. SAP system will shut down automatically when reaching

downtime phase, and SAP system will be restarted by upgrade tool after

downtime phase.

6. OS kernel parameters maintenance

   Dynamic OS kernel parameters become active automatically after

changing, while static OS kernel parameters will not become active until

OS restart. But no matter whether it is dynamic or static, It is

recommended to stop SAP system before changing OS kernel parameters. 

7. SAP profile parameters maintenance

   SAP profile parameters can be either changed via T-code :

RZ10/RZ11 on SAP system, or edited directly in the sap profile on OS

level. It is not necessary to stop SAP system. But to get changed

parameters activated, you have to restart SAP system.

8. database online backup + archive redo log

   It is recommended to do database online backup + archive redo log

every day. You can schedule daily background jobs to do it via T-code :

DB13 on SAP system, so there is no need to stop SAP system.

9. database offline backup

  It is recommended to do at least one full offline backup every

month. It is necessary to shut down database to do database offline

backup, which means that you should stop SAP system also.
