Oracle 10g Migration from Advanced Replication

To migrate the advanced replication methodology to the streams based replication, Oracle has provided help with a conversion tool. You can use the dbms_repcat.streams_migration procedure for this.

This procedure takes a list of replication groups to migrate and generates SQL script in a user-specified file. This script is then run at each master site to configure the Streams environment. The given replication groups must contain exactly the same masters. The script contains comments indicating what cannot be converted from Advanced Replication to Streams, and includes suggestions on how the script can be modified to handle the situation. Users can customize the generated script as needed.

Here is an example to show how the script is generated:

DECLARE
groups DBMS_UTILITY.NAME_ARRAY;
BEGIN
groups(1) := 'SALES';
groups(2) := 'RESEARCH';
groups (3) := 'PURCHASE';
DBMS_REPCAT.STREAMS_MIGRATION (
GNAMES => groups,
FILE_LOCATION => 'SCRIPT_DIR',
FILENAME => 'str_migrate.sql');
END;
/

The script_dir should be pre-created with the Create Directory command.
