MVIEW on-demand refresh - rollback space issue

Mindaugas Navickas



Platform Oracle on HP-UX
ORA-12008: error in materialized view refresh path
ORA-01562: failed to extend rollback segment number 2
ORA-01650: unable to extend rollback segment RBS_1 by 125 in tablespace

A big table is updated during a day on primary location. This table has MV log
created - using PK.
Once a day changes to this table has to be propagated to a remote site
(on-demand replication based on PK).

Most of times replication process works fine, however, there are times when
larger number of rows are updated. Then replication fails with errors above.
I know that most straightforward way would be to increase rollback tablespace
size on remote site, however, we are short of disk space on that site and
growing rollback tablespace (already 1.2G) just to accommodate this case it
doesn't makes much sense (most of transactions on that database are small).

<b>Is there a way of splitting replication transaction into number of

May be I am looking for something what does not exists, however, I hope, that
others might faced similar problem and can share how they solved that.

Thank you
