I am creating the recovery catalog but I am having some problems. Below is what I have done so far and the error message that I got.

SVRMGR> create tablespace CATALOG
2> datafile '/ora1/o2/DATA1/cat1rcat.dbf'
3> size 1000m;
Statement processed.
SVRMGR> create user rman identified by rman
2> temporary tablespace temp
3> default tablespace CATALOG quota unlimited on CATALOG;
Statement processed.
SVRMGR> grant recovery_catalog_owner to rman;
Statement processed.

machine oracle DATA1 /ora1/08/dbse
$ export ORACLE_SID=RCAT

machine oracle RCAT /ora1/08/dbse
$ rman catalog rman/rman

MY O/S is AIX

Any help?
