Re: RMAN memory issue

John P Weatherman



I am trying to get RMAN configured to handle one of my older databases.
The target is, the repository database I have created
an 8.1.7 repository from the target server and registered the target
database. So far, no problems. When I try to allocate channels, I am
getting ORA-4031 errors (see below). This happens for both maintenance
channels and regular backup channels declared in a run{} block.

RMAN> allocate channel for maintenance type disk;

RMAN-03022: compiling command: allocate
RMAN-03023: executing command: allocate
RMAN-00571: ===========================================================

RMAN-03007: retryable error occurred during execution of command:

pool","unknown object","large pool hea","KSFQ Buffers")
RMAN-10031: ORA-19624 occurred during call to

The catalog database should have plenty of room:

NAME                      TYPE     VALUE
------------------------------------ ----------- -----------------------
large_pool_size               big integer 33554432
shared_pool_reserved_size        big integer 26843545
shared_pool_size              big integer 536870912

as should the target (though the errors says it is coming from the RPC,
so this shouldn't be the issue):

NAME                      TYPE     VALUE
------------------------------------ ----------- -----------------------
large_pool_size               string    1572792
shared_pool_reserved_size        string    2000000
shared_pool_size              string    20000000

Has anyone else seen this or have any suggestions?
