Issue/Introduction

Log Analyzer for Db2 for z/OS (PLA) fails to read a compression dictionary and produces dump


LAE0294I Beginning of Inline Image Copy processing. 

LAE0418I Inline Image Copy process has ended abnormally with Condition Code: 000010. A DUMP with the title 'INLINE COPY TASK TERMINATION' was taken. The waiting module was LAA@ICGT. 

LAE0071W Unable to build expansion dictionary  from Image Copy  

LAE0069E Unable to expand compressed data. Data will be shown in dump format 

Environment

DB2 for Z/OS

Release: R20

Cause

Possible storage related problem or inability to obtain a compression dictionary from the tablespace. 

Resolution

It is possible this is a storage related problem. 

Review the sort parameters specified in the DYNSORT parameter in the job and try increasing them. 

Also change DYNSORT MSG option to (Y)es.

 

Example:

DYNSORT = (DSNUM(5),SPACE(50,25),MAINSIZE(2000),MSG(Y)) 

---------------

It is also possible that there is a problem obtaining the compression dictionary from the tablespace.

Try changing the detail level being used to IMAGCOPY

DMLREPT  = (LEVEL    (DETAIL) ...
to: 
DMLREPT  = (LEVEL    (IMAGCOPY) ...

In order to decompress data, a compression dictionary is required every time. Log Analyzer has sophisticated logic to detect and pick correct the compression dictionary for the data it is processing.   

Additional Information

The IBM REPORT RECOVERY utility can be used to diagnose the availability of a full image copy that covers the time frame of the extract. The IMAGCOPY setting will not be effective if there is no image copy available.
