Dual Node PCP configuration

Hi,

Here is what I'm trying to achieve:

Database :  DBNODE 1 and DBNODE2  (11gr2 RAC)

Application:  APP1 and APP2  (12.1.3 wITH rup6)

I want to configure APP1 and APP2 , both having Concurrent Processing node. My questions is what ia the requirement to acheive this? As per my understanding following are requirement:

1) Set the $APPLCSF and concurrent manager log environment variable on all the CP nodes pointing to a log directory on a shared file system.

Example : APPLCSF =/devshare/cm

2) Set the $APPLPTMP environment variable on all the CP nodes to the value of the UTL_FILE_DIR entry in init.ora on the database nodes. This value should be pointing to a directory on a shared file system
