2706367 - Default Deletion job and Archiving job is slow on JAVA PO PI systems - SAP ASE for Business Suite

• Archiving and "Default Deletion" jobs are slow on SAP JAVA AS - PO PI systems.
  
  
• "IdocDBTableCleanup" and/or "IdocDBTableCleanupPeriodic" jobs which run as part of  / alongside the "Default Deletion" job are slow.
  
  
• The underlying slow sql queries are:

SELECT XI_MSG_NO FROM XI_IDOC_IN_MSG WHERE OUT_TIME <= convert(datetime,'10/10/18',3)
AND XI_MSG_NO NOT IN (SELECT MSG_ID FROM BC_MSG WHERE DIRECTION= 'OUTBOUND')
AND XI_MSG_NO NOT IN (SELECT PARENT_MSG_ID FROM BC_MSG WHERE DIRECTION = 'OUTBOUND' AND "PARENT_MSG_ID" IS NOT NULL)

SELECT XI_MSG_NO FROM XI_IDOC_IN_MSG m
WHERE m.OUT_TIME between '2018-07-18T00:00:00.000' and '2018-07-18T23:59:59.000'
AND XI_MSG_NO NOT IN (SELECT PARENT_MSG_ID FROM BC_MSG WHERE DIRECTION = 'OUTBOUND' AND PARENT_MSG_ID IS NOT NULL)
AND XI_MSG_NO NOT IN (SELECT MSG_ID FROM BC_MSG WHERE DIRECTION = 'OUTBOUND')

SELECT "OTX"."AUTO_NUMBER" "OTX_AUTO_NUMBER_autoNumber" FROM "XI_IDOC_OUT_TREX" "OTX" WHERE "OTX"."AUTO_NUMBER" NOT IN (SELECT DISTINCT "OMSG"."REF_NUMBER" FROM "XI_IDOC_OUT_MSG" "OMSG") AND "OTX"."AUTO_NUMBER" NOT IN (SELECT DISTINCT "OACK"."REF_NUMBER_TREX" FROM "XI_IDOC_OUT_ACK" "OACK")

• On the ASE database, processes are seen to block on queries accessing tables, BC_MSG and BC_MID_CON_TRFC .
  
  
• NW JAVA PO/PI tables grow large in size if the Deletion jobs do not run in a timely manner, as expected.
