Replication problem

[vanirame]

We are using asynch propogation for one of the master group and using queue table def$_aqcall in system tablespace.
As there is more I/O generated on system tablespace, we want to move que table to other tablespace.
If we stop replication ,create another table in other table space unser same schema with same table defination ,drop original and rename the new table to def_aqcall, Will it effect any thing ?
This is very critical so please help.

This is a common problem. Moving def$_aqcall table to another tablespace should be fine.

You may want to take a look at the following steps:

Moving the SYSTEM catalog tables in Oracle8:
============================================

1. Take a backup of the site where the SYSTEM catalog tables are
going to be moved.

2. Make sure deftran, defcall, deferror and dba_repcatlog on the
site where the tables are going to be moved to are empty.

3. Connect to Sql*Plus as REPADMIN and issue for EACH repgroup:

SQL> EXECUTE DBMS_REPCAT.SUSPEND_MASTER_ACTIVITY('GNAME');

4. Export user SYSTEM.

$ exp system/manager file=move.dmp

5. Connect to Sql*Plus as SYSTEM. Drop the following tables in
the order specified below:

drop table SYSTEM.DEF$_CALLDEST;
drop table SYSTEM.DEF$_DEFAULTDEST;
drop table SYSTEM.DEF$_ERROR;
drop table SYSTEM.DEF$_ORIGIN;
drop table SYSTEM.REPCAT$_REPSCHEMA;
drop table SYSTEM.DEF$_DESTINATION ;

6. Connect to Sql*Plus as REPADMIN and issue:

SQL> EXECUTE DBMS_AQADM.DROP_QUEUE_TABLE('SYSTEM.DEF$_AQCALL',TRUE);

SQL> EXECUTE DBMS_AQADM.DROP_QUEUE_TABLE('SYSTEM.DEF$_AQERROR',TRUE);

7. Connect to Sql*Plus as SYS and issue:

SQL> ALTER USER SYSTEM DEFAULT TABLESPACE
QUOTA UNLIMITED ON ;

SQL> ALTER USER SYSTEM QUOTA 0 ON SYSTEM;

SQL> REVOKE UNLIMITED TABLESPACE FROM SYSTEM;

8. Connect to Sql*Plus as SYSTEM and run the script "catdefrt.sql"
located in the "$ORACLE_HOME/rdbms/admin" directory.

Note: The errors on some CREATE TABLE statements and CREATE
INDEXES of mature tables or indexes indicating they
already exist can be safely ignored.

9. Import the tables in the order listed from your export file
from step 4 above.

SYSTEM.DEF$_DESTINATION
SYSTEM.DEF$_CALLDEST
SYSTEM.DEF$_DEFAULTDEST
SYSTEM.DEF$_ERROR
SYSTEM.DEF$_ORIGIN
SYSTEM.REPCAT$_REPSCHEMA

Example:

$ imp
Username: system
Password:

. . importing table "DEF$_ERROR" 0 rows imported
. . importing table "DEF$_ORIGIN" 0 rows imported
. . importing table "REPCAT$_REPSCHEMA" 6 rows imported

10. Connect as user SYS and issue:

SQL> GRANT UNLIMITED TABLESPACE TO SYSTEM;

Hi vaniram,

I am also faced same problem. But I have solved the problem very easily. by default DEF$_AQCALL will reside in system tablespace. This will grow very fast.
just move the table to another tablespace.
frequently you have truncate the table.

If you are not able to do the above things plz let me know I will forward you the commands.
