JR58714: ARTIFACT INDEXER CAUSES MORE MEMORY TO BE USED IN THE BRANCH CACHE

8.5.7.201706-WS-BPM-IFJR58714
bpm.8600.cf2017.12.delta.repository

APAR status

• Closed as program error.

Error description

• You might see an Out of Memory error or high memory use when the
  server starts or when the artifact index is rebuilt in IBM
  Process Center.
  

Local fix

• Reduce the branch-context-max-cache-size (for example, 5).  For
  more information about the branch cache, see "Using process
  instrumentation data for cache tuning"
  (https://www.ibm.com/support/knowledgecenter/SSFPJS_8.6.0/com.ib
  m.wbpm.admin.doc/topics/perf_tuning_instrument_data.html).
  

Problem summary

• When the server is started for the first time after you upgrade
  to IBM BPM V8.5.7, the new indexer tries to rebuild the whole
  index. In the process of rebuilding the index, the indexer
  covers every branch in Process Center, causing the branch cache
  to grow.

  IBM Business Process Manager (BPM)
  IBM BPM Express
  

Problem conclusion

• A fix that ensures the branch contexts are not cached during
  indexing will be included in a future release of IBM BPM.
