Problems in creating Materialized View from 10g R2 to 11g
513219Mar 2 2009 — edited May 8 2009Hi,
We have two databases in 10g Release 2. These databases are on two different servers and we use
Materialized views to replicate data between these servers. We are currently using 64 bit version of
oracle 10g release 2 for LINUX.
Oracle Database 10g Release 10.2.0.1.0 - 64 bit Production
PL/SQL Release 10.2.0.1.0 - Production
CORE 10.2.0.1.0 Production
TNS for Linux: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
We use CENTOS 5 - 64 bit edition
We upgraded one of the databases to 11g (We exported the data from old database and
imported it in new database) . Then we tried to create a Materialized view with incremental refresh
on it where the base table is in the second Oracle 10g database.
The problem is that it is not letting us create the view with FAST Refresh. It kept on giving ORA-12028
error. We tried different remedies suggested on forums like creating a view with ROWID, but still it
continued giving us the same error. We also synchronized the characterset of Oracle 10g and Oracle 11g
installations but still it did not work.
Our base table size is pretty large (over 10 Million records) and if we do a full refresh, it takes hours to
refresh it.
Without incremental refresh, we will not be able to fucntion, and to upgrade both database simultaneously
we will need a large down-time which also we can not afford.
Please advise what should we do.
Best Regards
Madhup
