Error description
When the hdr file used for historical collection at the TEMS or TEMA is zero bytes then then historical collection fails to recover from this and shuts down historical collection for the table being collected. The code should be able to determine this condition and recover. RECREATE INSTRUCTIONS: Make a zero byte *.hdr file for any historical collection table and the start collection for that table. The UADVISOR will start and then shutdown based on the zero byte file. The code should treat this as no file exists and create a new hdr file and overwrite the zero byte hdr file.
Local fix
Erase the zero byte file and restart the historical collection.
Problem summary
Historical collection fails to start if the header file (.hdr) is zero bytes. The header file used on the monitoring server and monitoring agent for historical collection is currently not tested for zero bytes, and therefore, historical collection fails to start. A zero byte header file can occur if the process is terminated in the middle of the header creation or if the krarloff historical short-term offload program is used while historical collection is enabled. The zero byte header file also causes display of data on the portal to fail.
Problem conclusion
The agent framework now tests for a zero byte header file and recreates the header file based on the historical table name. This change is required for the historical collection service and historical reporting. The fix for this APAR is contained in the following maintenance packages: | fix pack | 6.2.2-TIV-ITM-FP0009 | fix pack | 6.2.3-TIV-ITM-FP0002
Temporary fix
Locate header files with the ".hdr" file extension in platform-specific directories: On the monitoring agent, ITM_HOME\TMAITM6\logs\History\<product-code> (Windows) ITM_HOME/<architecture>/<product-code>/hist (UNIX/Linux) Example: /opt/IBM/ITM/aix523/t6/hist (UNIX/Linux) On the monitoring server, ITM_HOME\CMS (Windows) ITM_HOME/tables/<tems-name> (UNIX/Linux) Example: /opt/IBM/ITM/tables/mytems Delete the zero byte header files, and restart the historical collection. Alternatively, recycle the affected monitoring server or monitoring agent.
