Database Software

Hello,

i usually make entire database backup and archivelog, (when necessary) ,  of  my 3 node RAC thru 8 sbt channels and connected to local node1 only , and connected at the same time to Rman catalog.

In this node1  i have fiber channel connected to legato storage network. I have another second fiber in node3  but i don´t use it for scheduled backup.

This is my script for backup:

connect target rman/rman@node1;

connect catalog rman/rman@RMAN;

resync catalog;

run {

  allocate channel t1 type 'SBT_TAPE';

  allocate channel t2 type 'SBT_TAPE';

  allocate channel t3 type 'SBT_TAPE';

  allocate channel t4 type 'SBT_TAPE';

  allocate channel t5 type 'SBT_TAPE';

  allocate channel t6 type 'SBT_TAPE';

  allocate channel t7 type 'SBT_TAPE';

  allocate channel t8 type 'SBT_TAPE';

  send 'NSR_ENV=(NSR_SERVER=legato,NSR_CLIENT=node1,NSR_DATA_VOLUME_POOL=oracle)';

  backup full format='bck_online_%d_%u_%s'

  filesperset=1

  (database include current controlfile);

  release channel t1;

  release channel t2;

  release channel t3;

  release channel t4;

  release channel t5;

  release channel t6;

  release channel t7;

  release channel t8;

}

My question:

How i could take advantage from the 3 node RAC and from the second fiber channel legato storage network i actually don´t use.?

Do you see any to change ?

thanks and regards.
