Re: Influencing commit interval of read-only replication's refresh gr
Tamas, The purpose of the refresh is to make the snapshot site identical to the master site as of the point in time that the refresh began. As such the refresh is a single transaction and must either commit or rollback in its entirety. You don't specify what version the snapshot site is, but on O8 you can specify the RBS to use during the refresh. The only options I see are: 1. Increase the RBS and/or RBS tablespace. 2. Reduce the number of snapshots in the refresh group. 3. Reduce the refresh interval HTH, -- Anita --- Szecsy Tamas [EMAIL PROTECTED] wrote: Hi, does some one know of a way to force the refresh process of a read-only snapshot group to commit at predefined intervals: by table, by n number of rows or any other way?

Influencing commit interval of read-only replication's refresh gr

Hi, does some one know of a way to force the refresh process of a read-only snapshot group to commit at predefined intervals: by table, by n number of rows or any other way? The problem that we are facing is that a refresh group has some rapidly changing tables and the rollback segment is not big enough. TIA, Tamas Szecsy -- Tamas, A refresh group is a set of related (through FKs and the like) tables. Not committing before everything has been replicated is the Oracle way to fudge the integrity constraint violation issue (don't forget that they have one log per table, not a single chronological log). Either you begin writing your own refresh functions, or you find a way to split your refresh group into subgroups for which referential integrity would not be a problem, or you increase the rate of refresh. I don't see anytging else.
