SAP BASIS NOTES -6

Operation Modes :-
There are two types of operation mode 
1) Day Mode
2) Night Mode

• In real time scenario during day mode, we have maximum number of users logging into SAP system hence, we need maximum number of dialog work process to be set.
• During night mode, maximum number of background work processes is scheduled. Hence we need maximum number of background work processes in the night.
• In order to make these changes we need to setup operation mode

Note: During switching operation modes, neither the instance nor the effected work processes need to be restarted.

Setting up of operation Mode :-
• In the command prompt of SAP execute the Transaction code RZ04
• Create operation mode Day, Night
• Call all active instances of the system
• Select work processes that are needed based on the operation mode and assign to it as default.
• Switching up of operation modes should be set in SM63 (Time Table maintenance)
• Click Save
Note:
• Work process allocation is made primarily between dialog and background.
• Work process type = Dialog, Background, Class A, Update, V2 Update, Enque and Spool.
• Class A work process are allocated primarily for background jobs of priority high.

Maintain Operation mode and Instances :-
1) Select [Instance/Operation Modes]
2) Select [create new instance]
3) Enter Hostname, select start profile, and instance profile.
4) Click on [save] button
5) Work process distribution window pop’s up
6) Select type of operation mode and tune the number of work processes and click on [save].
Note: In live environment we will not be required to perform this step regularly, and instead we choose Instance -> Maintain Instance -> Work Process Distribution.
7) Click on [consistency check] Button. Note: Always use consistency check button because operation mode switch will not work if there is any inconsistency.
