RDBPROD: Performance Issue When Executing Query (Doc ID 578202.1)

Last updated on MAY 25, 2017

Applies to:

Oracle Rdb Server on OpenVMS - Version 7.1.4.5 to 7.2.2 [Release 7.1 to 7.2]
HP OpenVMS Itanium
HP OpenVMS Alpha

Symptoms

When a query executes in the context of a READ ONLY transaction, the query runs for just under 5 minutes and returns 24,149 rows. When the exact same query runs in the context of a READ WRITE transaction, the query runs for over 7 hours and eventually aborts with an EXQUOTA error.
