IT41349: With DRINTERVAL 30 or more we get -242/-154 error in online.log when Auto Update Statistics Evaluation task is run.

APAR status

• Closed as program error.

Error description

• With HDR secondary paired to primary and DRINTERVAL is set to 30
  or more, on primary server we get
  -242/-154 error in online.log when ever Auto Update Statistics
  Evaluation task is run.
  
  06/24/22 09:01:27  SCHAPI:  last statement CREATE INDEX
  aus_work_info_idx2 ON aus_work_info(aus_info_partnum)
  06/24/22 09:01:27  SCHAPI: [Auto Update Statistics Evaluation
  47-4] Error -242 Could not open database
  table(informix.aus_work_info).
  
  06/24/22 09:01:27  SCHAPI: [Auto Update Statistics Evaluation
  47-4] Error -154 ISAM error: Lock timeout Expired
  
  Auto Update Statistics Evaluation task drops and re-creates some
  tables in sysadmin database, when this task re-creates the
  index, primary server will ship the newly created indexes. In
  this process we get -242 error while AUS Evaluation task
  creating the index aus_work_info_idx2 on aus_work_info.
  
  If we set DRINTERVAL to 0, then HDR_TXN_SCOPE takes precedence
  and we no longer see this error.
  We don't see -242 error when we set the DRINTERVAL to smaller
  value compared to default value.
