Hi,
Yes you can increase or decrease the Background/dialog/Update work process easily.I will suggest you to go for operation mode set up for few days to monitor system performance and the impact of increasing or decreasing the work process .
Run transaction code- RZ04
Then click on Instance/operation mode and you will see below screen.
Then you can double click on daytime and you will get below screen and you can change dialog/background/update/enqueue work process as per your desired value/system usages.
You can do the same thing for nighttime. If you want to keep same number of work process for day and night time then keep them as same for daytime and nighttime. Or if you wish you can have more dialog work process in day time and less dialog work process in night time. As the dialog users are very lesser in night.
Now the important point is how to decide day and night timings,
To maintain operation mode switch timings, goto transaction SM63 as shown below and select normal operation (24hr) mode
To maintain operation mode switch timings, goto transaction SM63 and select normal operation (24hr) mode
Click on change button and set the operation mode intervals for day and night.
First let us set for day operation mode by clicking on the start time of the day interval and then navigating to Operation mode -> Select interval. Then start interval is marked.
After this place cursor at the end interval and again navigate to Operation mode -> Select interval and confirm to mark the entire interval of day operation mode
In the above screen, you can figure the interval marked is highlighted in different colour. Now assign operation mode as below for the highlighted area by clicking on assign button in the below screen
P.S. - You cannot change Spool work process through RZ04 but it can only be changed through RZ10 by setting the desired value of the parameter "rdisp/wp_no_spo".
