Known Problems

SAP is aware of the following problems in the enqueue service environment.

Profile File Cannot Be Read Under UNIX

Symptom

You will get an error on the console like:

sapparam(6): ./cfg/kernel/enqt.pf: missing '=' in line 26

kkkkk

In future various problems may occur.

·        The VM immediately crashes with a stack overflow.

·        Unusual errors occur only after a while.

Cause of Error and Fixing Error

The profile file contains "\r\n", which is why the profile cannot be read.

Delete these characters from the profile.

Shared Memories Stand Still

Symptom

The start of the enqueue server fails on UNIX, because older shared memories are still there.

Cause of Error and Fixing Error

Delete the old shared memories manually by entering:

cleanipc <SAPSYSTEM> remove

You can take the value of <SAPSYSTEM> from the profile file enqsrv.pf.

cleanipc is in /usr/sap/<SID>/SYS/exe/run.
