RMAN incompatible with TARGET database

Question

I have two databases:
The database with the catalog, version 8.1.7.
The database to be backed up (target), version 8.0.6.
When I try to connect to the target, I get an error stating: Recovery Manager incompatible with TARGET database: RMAN 8.0.4 to 8.0.4 required
I've tried changing the "compatible" parameter to 8.0.4, but then I get an error when I restart the database (regarding locally managed tablespaces, which I am not using).
Any idea what I need to do to connect to the target database?
thanks....

Hi !
I guess you have confused the compatible init.ora parameter with RMAN compatible parameter ,
They are entirely different. The excerpts here, which i have taken from the Oracle online docs should
clear your problem.
The compatible parameter specifies the minimum acceptable release of the RMAN executable that can function with the catalog. For example, if the recovery catalog compatibility is set to 8.1.4, then only an RMAN executable of release 8.1.4 or later can connect to the catalog.
You cannot set the compatible parameter to a version that is not supported by the currently-installed DBMS_RCVMAN or DBMS_RCVCAT packages. If you try to set compatibility to a version that is not supported by one of the packages, then you receive an error message that indicates the lowest and highest value you can set, as in the following example:
RMAN> configure compatible = 8.0.1;
RMAN-03022: compiling command: configure
RMAN-03026: error recovery releasing channel resources
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure during compilation of command
RMAN-03013: command type: configure
RMAN-06455: illegal compatible value 8.0.1: must be between 08.00.04 and 08.01.06
To view the compatibility level of the recovery catalog:
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Start a SQL*Plus session and connect to the recovery catalog database as the recovery catalog owner. For example, enter:
SQL> connect rman/rman@rcat
Issue the following query:
SQL> SELECT value FROM config WHERE name='compatible';
VALUE
080106
To create an 8.1.6 recovery catalog that is usable with a pre-8.1.6 RMAN executable:
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
This procedure assumes that you have the use of both an 8.1.6 and pre-8.1.6 RMAN executable. The method employed it to use a pre-8.1.6 RMAN executable to create the recovery catalog, and a release 8.1.6 RMAN executable to upgrade it. The compatibility level is automatically set to 8.0.4, which has the implications described in Table 3-1.
Use a pre-8.1.6 RMAN executable to connect to the catalog database. For example, enter:
% rman catalog rman/rman@rcat
Recovery Manager: Release 8.1.5.0.0
RMAN-06008: connected to recovery catalog database
Create the recovery catalog and then exit. For example, enter:
RMAN> create catalog;
RMAN> exit
Note:
If you use a release 8.0 RMAN executable to create the catalog, you must use the catrman.sql script to create the recovery catalog.
Use the 8.1.6 RMAN executable to connect to the newly created recovery catalog:
% rman catalog rman/rman@rcat
Recovery Manager: Release 8.1.6.0.0
RMAN-06008: connected to recovery catalog database
Upgrade the recovery catalog to release 8.1.6:
RMAN> upgrade catalog;
RMAN> exit
The compatibility level of the recovery catalog is now automatically set to 8.0.4.
