What is SAP Profile?
SAP profiles are
operating system files that contain instance configuration information. SAP
systems can consist of one or more instances. Individual configuration
parameters can be customized to the requirements of each instance. You can use
these parameters to configure the following:
·
The runtime
environment of the instance (resources such as main memory size, shared
memory, roll size)
·
Which services the
instance itself provides (work processes)
·
Where other
services can be found (database host)
The SAP
profiles are stored in a special file directory. This directory can be made
accessible from all hosts, depending on current requirements.
UNIX
systems:/usr/sap/<SID>/SYS/profile
Microsoft
Windows NT systems:\\<SAPGLOBALHOST>\sapmnt\<SID>\sys\profile\
Types of SAP Profiles:
During
installation, three profiles are created in the file system:
·
DEFAULT.PFL ------------Default profile
·
START_<Instance> ------------Start Profile
·
<SID>_<Instance> ------------instance profile
These profiles contain the parameters that
determine the operating system resource usage of the instance, for example,
the number of work processes, the buffer sizes.
You import and
activate these profiles using the profile maintenance tool.
This profile parameters are maintained in RZ10.
