Question:We are carrying out an application installation. The installation is failing with the following message in the .nfy file .
ADM11001E DB2 did not create a memory segment for running fenced routines. This was specified by the use of DB2_FMP_COMM_HEAPSZ registry variable.
How can I bypass these errors to allow the installation to finish?
Answer: I’ve seen this problem plenty of times where a DBA has set the DB2 registry value : DB2_FMP_COMM_HEAPSZ=0. On many occasions , it is to force fenced routines such as the DB2 Health Monitor :Monitor health of instance and databases to not run.
It is also commonly used as a method to decrease the DB2 footprint size
To stop the ADM11001E error occurring and if DB2_FMP_COMM_HEAPSZ = 0 , then the simple fix is to change the DB2 registry variables
To change the registry value , you can either change the value
Or delete the variable
