There are many LAE0222E error messages in the Log Analyzer job output

• Log Analyzer for DB2 for z/OS

Issue/Introduction

Noticed that on this Db2 subsystem executing Log Analyzer for Db2 for z/OS (PLA) there are many such messages:

LAE0222E Error processing compression dictionary from the log for  
         tablespace DB-Name.TS-Name instance 0001                   
         partition  00001  RBA/LRSN ...          

Afraid that this will affect the performance of the Log Analyzer job runtime.
Is it possible to avoid or change this situation?

Resolution

The combination of messages LAE0222E, LAE0247W and LAE0223I is pretty common when Log Analyzer Job reads compression dictionary
written to the Db2 log by LOAD or REORG utility.
 
First two messages LAE0222E and LAE0247W state that the Log Analyzer Job founds a compression dictionary that has been corrupted
and marked invalid by Db2. After the invalid dictionary LOAD and REORG utilities write valid dictionary and it is marked by LAE0223I.
 
This has no negative effect on performance.
