Primary TIMOS Memory Grows When Secondary Synchronizes Transient Objects (Doc ID 1303103.1)

Last updated on MAY 11, 2021

Applies to:

Oracle Communications Billing and Revenue Management - Version and later
Information in this document applies to any platform.


In a customer setup, the primary TIMOS instance, after starting up, consumes around 20GB of memory. This is a stage when data migration is complete, indexing is done, and memory growth is very limited (up to 64 KB in a second).

Now, if secondary TIMOS instance starts and it comes to synchronize bulk objects, primary TIMOS grows with extra 5GB during 2 minutes, even though it does not need to store any additional data.


- initially: primary TIMOS down, secondary TIMOS down.
- at 2011-02-12 14:44:45 primary TIMOS is started
- at 2011-02-12 16:21:54 initial data migrations is done for primary (TIMOS state transition from 'ActiveDataMigrationInProgress' to 'ActiveDataMigrationComplete'.)
- at 2011-02-12 17:17:55 primary TIMOS instance needs 19836036 KB of memory
- at 2011-02-12 17:17:56 secondary TIMOS is started.
- at 2011-02-12 18:08:08, primary TIMOS instance needs 19896180 KB of memory (60MB growth in 47 minutes)
- at 2011-02-12 18:08:09 bulk data migration starts (primary: TIMOS state transition from 'ActivePassiveReadyForSynchronize' to 'ActiveBulkPayloadMigrationInProgress'.)
- at 2011-02-12 18:12:34 bulk data migration ends (primary: TIMOS state transition from 'ActiveBulkPayloadMigrationInProgress' to 'ActiveBulkPayloadMigrationComplete'.
- at 2011-02-12 18:12:35, primary TIMOS instance needs 24809412 KB of memory (4,9GB grow in 4,5 minutes!)

Impact on Business:
TIMOS memory consumption reaches OS limit rapidly, and TIMOS requires frequent restarts. This lead to heavy load (application, database) and impacts other processes, such like billing accounts.

Expected result:
During bulk data synchronization, primary TIMOS memory growth should not be as high as 5GB
