How to change SAP Profile parameters
This blog post is kind of a pre-req or sideline to my previous blog post on changing the ABAP buffersize because obviously at some point you will want to change or check system parameters for other things like the initial Solman (Solution Manager) installation.
First things first – Take a backup of the directory (And all containing files) that hold your system settings.
Goto Transaction RZ10
Import Profiles already setup from installation:
There should be 3 profiles for each server instance, a Default Profile, Instance Profile and Start Profile:
Now you can edit your current profiles at will, Normally I have in the past edited the instance profile.
The Administrative Data management section gives you the following information summary:
1. Profile Name
2. What Version it is up to
3. The Profile Description (Like “Auto Generated”)
4. Where in your network this profile is stored
5. Reference server for profile parameter check
6. An audit Trail so you can see who has done changes
The Basic Maintenance provides some basic system settings, so far I have not had to play with these yet but I’m sure someone will have a reason for altering them if necessary.
The Extended Maintenance is where I have done the majority of work in, Here you can change heaps of things, but some of the system changes I have made here include:
2. Number of dialogue work processes
3. Number of Background work processes
4. J2EE settings
5. Server ports and many other available options for tuning.
My advice though is that unless you need to change something, don’t change it for the sake of it. SAP does a pretty good job of auto allocating the right system parameters.
