OBIEE 12c Initialization Blocks That Refresh Dynamic Repository Variables Cause Memory Consumption (Doc ID 2220081.1)

Last updated on JULY 31, 2017

Applies to:

Business Intelligence Suite Enterprise Edition - Version 12.2.1.0.0 and later
Information in this document applies to any platform.

Symptoms

An OBIEE Repository (RPD) has many system date time based Dynamic Repository Variables which get frequently refreshed with initialization blocks [ init blocks ].
For example: 75 init blocks that have refresh rate of 1 hour.

Memory and then swap space get used up (as observed with OS tools - top, topas, task manager, etc) within a day and the system becomes unresponsive.

When the refresh rate is changed from one hour to twelve hours, the memory and swap space are still consumed but takes several days.

Changes

Upgrade from 11g to 12c.
