Description
Encountered the following error during Performance Analysis for DB2 agent installation
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ ERROR: +
+ The monitored instance version (N/A) is not supported by the Performance +
+ Analysis Agent. +
+ Please select a different instance. +
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ -
Cause
Agent fails to read data from the file : /db2home/mssadm/sqllib/.ftok
It was found that the file size was 0 byte.
The .ftok file is generated based on the current time and other information. When starting the instance, DB2 reads the .ftok file and creates a standard interprocess communication key (IPC key) which is later supplied to other subroutines for memory allocation. Without the ftok Performance Analysis for DB2 cannot complete the installation.
-
Resolution
Regenerate the .ftok file using the following steps or contact IBM directly.
cd ~/sqllib
mv .ftok .ftok.old
db2ftok
db2start
