Database Software

I have a problem in which I try to migrate a 10g database to use a new recovery catalog database, 11g. I connect to target and catalog but after issuing register database it hangs as follows:


server123:oracle 1> rman target / catalog catuser/catpw@CATALOG456

connected to target database: TRGT (DBID=823102274)
connected to recovery catalog database

RMAN> register database;

database registered in recovery catalog
starting full resync of recovery catalog

[[--hangs here (have let it try to do the resync for +3 hours)--]]


When I look from the recovery catalog I see it can connect to it:

SQL> r
1 SELECT s.inst_id,
2 s.sid,
3 s.serial#,
4 p.spid,
5 s.username,
6 s.program
7 FROM gv$session s
8 JOIN gv$process p ON p.addr = s.paddr AND p.inst_id = s.inst_id
9* WHERE s.type != 'BACKGROUND'

INST_ID SID SERIAL# SPID USERNAME PROGRAM
---------- ---------- ---------- ---------- ---------- ---------------------------------------------
1 126 19297 6229 catuser rman@server123 (TNS V1-V3)



However, from v$session_wait I can see it is idling:

SQL> select sid,wait_class,seconds_in_wait,wait_time,state,event from v$session_wait where SID = '126';

SID WAIT_CLASS SECONDS_IN_WAIT
---------- ---------------------------------------------------------------- ---------------
WAIT_TIME STATE EVENT
---------- ------------------- ----------------------------------------------------------------
126 Idle 507
0 WAITING SQL*Net message from client





Theres plenty of space left in datafiles in the recovery catalog database. The target is 10g

SQL> select * from v$version;

There are many other databases registered to that recovery catalog database, 10g's and 11g's. I can connect from the recovery catalog database server to the target database server, even using sqlplus. I have done crosschecks and delete expired archivelogs/backups/copies while connected only to target.

I didn't find anything relating to this except this but its about 10g/10g setup and in 11g the indexes are in place: http://pythianpang.wordpress.com/2010/07/29/rman-resync-catalog-hang-10g-workaround/

Any thoughts?
