The collector home directory is the directory into which saposcol writes its data and looks for the dev_coll trace file and the shared memory backup file coll.put . This directory also contains configuration files from the RMON-MIB saposcol variant. By setting a profile parameter, you can use a different directory. In this case, saposcol must be started using a profile. For example:

where the file /usr/sap/C11/SYS/profile/saposcol.pfl contains only the following lines:

The profile parameter exe/saposcol (not a saposcol profile parameter itself) is also important for the R/3 instance. To start, stop or view the status of saposcol from R/3, the parameter must point to a correctly installed saposcol .

If several R/3 instances are running, for example, each with a different R/3 Release, you must ensure that each instance is using the same (latest) version of saposcol . For example, if the XYZ System is a more recent release than C11, and both systems are running an instance on one host, then set the instance profile parameters in both systems as follows:

This ensures that each instance on this one host uses the same saposcol . The Operating System Monitor status displays whether the current saposcol is the one which you started.
