Dear all,
I'm trying to create a recovery catlog and I get the following error message. Do you see what is wrong with instruction: (oracle version 8.1.5)

Recovery Manager: Release 8.1.5.0.0 - Production

RMAN-06005: connected to target database: SOLDB (DBID=2945300576)

RMAN> create catalog tablespace rman_ts;
RMAN-00571: ===========================================================
RMAN-00569: =============
== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-06002: command not allowed when not connected to a recovery catalog

RMAN> exit;

Recovery Manager complete.

========================================
The Insructions I use are:
1. Create tablespace rman_ts
2. create user rman_dba
3. Grant the following permissions:
grant recovery_catalog_owner to rman_dba;
grant connect, resource to rman_dba;

4. Create rman catalog:
rman target rman_dba/rman_dba msglog=catalog.log
create catalog tablespace rman_dba;
exit;
and get the above error message.

Do you anything wrong

5. register the database for the catalog

Regards
Hamid
