Auxiliary channel allocation in TSPITR with RMAN-managed instance

Question

Hi,
I'm trying do perform TSPITR with RMAN-managed auxiliary instance. All backups are stored on tape. I need to send MML environment values while allocating auxiliary channel to connect to correct NetWorker server and send other NetWorker parameters.
Unfortunately I have issues with sending these params - I can't send them from recover RUN block, as auxiliary instance does not exists at the time when I'm starting to execute script. (example from test env using disk channels)
RMAN> RUN
2> {
3> ALLOCATE CHANNEL c1 DEVICE TYPE disk;
4> ALLOCATE AUXILIARY CHANNEL aux1 DEVICE TYPE disk;
5> SET NEWNAME FOR DATAFILE 1 TO '/u01/backup/tspitr/10gdb2/system01.f';
6> SET NEWNAME FOR DATAFILE 2 TO '/u01/backup/tspitr/10gdb2/undo01.f';
7> SET NEWNAME FOR DATAFILE 7 TO '/u01/backup/tspitr/10gdb2/hr_bak01.f';
8> SET AUXILIARY INSTANCE PARAMETER FILE TO '/home/oracle/params_auxinit.ora';
9> RECOVER TABLESPACE hr_test UNTIL TIME "SYSDATE - 1/4"
10> AUXILIARY DESTINATION '/u01/backup/tspitr/10gdb2';
11> RELEASE CHANNEL c1;
12> RELEASE CHANNEL aux1;
13> }
allocated channel: c1
channel c1: sid=141 devtype=DISK
released channel: c1

RMAN-06174: not connected to auxiliary databaseI know I can do it using configure, but is there any way to set this on session level?

Answer 1

What can be done here, is to CONFIGURE AUXILIARY CHANNEL to set appropriate params for auxiliary instance (without allocating channels manually).
I just wanted to know, if I can do it just for this one session (without permanent modification). What I can do, is:
CONFIGURE AUXILIARY CHANNEL DEVICE TYPE sbt_tape PARMS 'mml settings';
CONFIGURE CHANNEL DEVICE TYPE sbt_tape PARMS 'mml settings';
CONFIGURE DEFAULT DEVICE TYPE TO sbt_tape;
RUN
(new names, auxiliary parameter file)
RECOVER TABLESPACE ...
CONFIGURE AUXILIARY CHANNEL DEVICE TYPE sbt_tape CLEAR;
CONFIGURE CHANNEL DEVICE TYPE sbt_tape CLEAR;
CONFIGURE DEFAULT DEVICE TYPE CLEAR;I just wanted more 'elegant' solution.
Update:
Due to bug no. 4768353 there is no possibility to use automatic channel allocation in auxiliary instance. Problem resolved by using own customized auxiliary instance started before recovery process. Channels have been allocated manually using ALLOCATE AUXILIARY CHANNEL c1 DEVICE TYPE sbt... on already running aux.
