For ECC 6.0 ABAP Stack, following are the various SAP Profiles:

All of these profiles are located under /sapmnt/<SID>/profile (Appropriately on Windows Environment)

1) DEFAULT PROFILE (DEFAULT.PFL)=> This file contains Name of SAP System, Database system, name of enqueue server and so on. This profile will exist uniquely no matter if there are more than one application servers of SAP system i.e. There will be only one default profile.

Each SAP R/3 instance to be started reads this profile first. Hence the information specified in this profile is very vital for functioning of the SAP system

2) START PROFILE (START_<INSTANCE>_<HOST>)=> Start profile is specific to instance. It means if there are 4 application servers, each will have its separate start profile with the settings specific to that instance.

The start-up process of SAP system is controlled by the start profile. Here the services e.g.- message, gateway, dialog batch etc that are to be started are listed. In other words, the start profile determines how, where and under what name individual SAP R/3 services and processes are to be started.

For the start profile, default names are assigned during the installation of an instance based on the services that are running on that instance. For example DVEBMGS00 instance (Central Instance) has the following services: D-Dialog, V-Update, E-Enqueue, B-Batch, M-Message, G-Gateway, S-Spool.

3) INSTANCE PROFILE (<SID>_<INSTANCE>_<HOST>)=> Like start profile, instance profile is specific to an instance. It means if there are 4 application servers, each will have its own instance profile with settings specific to each instance.

Basically, the run-time environment is configured in the instance profile. In instance profile parameters specific to an instance can be set like Auto GUI Log-out time, no. of work processes, memory related parameters etc.

Summary

In case of any changes to System Profile (DEFAULT.PFL) you must restart all the instances of the SAP System as this is common to all the instances.

However in case of any changes to instance profile, it is sufficient to take restart of only that particular instance for the changes to take effect.

Sequence of Files read while SAP Starts:

1) START Profile of various instances are read by the sapstart program

2) DEFAULT Profile is read

3) Finally, INSTANCE profile of various instances are read and system is started.

P.S.- Do not get confused with the order that DEFAULT should be read before START.

There is no way that we can really give you advice about parameter changes without logging on to your system. That is why SAP provides 3 Free Annual EarlyWatch Checks. Contact SAP and schedule one of these checks as soon as possible.

Saiya,

Technically speakign it wont be feasible if i provide you profile parameters. It differs environment to environment and a lot of other things.

You should try to study and understand each of the parameters within the profiles and you shall be able to tune them accordingly.

Good place to start would be RZ10 in your Application Server ABAP.

Select the profile =>  Extended Maintenance => Display Mode.

Now for each of the parameter, you can do SAP Help (F1) and understand what does that parameters does actually. In fact SAP provides information on default and recommended values for each of the parameters.

Hope you shall now be able to make a move about the same!
