You need to take a look at the Node Manager log to see why it is shutting down.
Node Manager doesn't shut the system down on its own. Some other process tells NM to do the shutdown. Dumping the Node Manager log will tell you what process that is. It will NOT be a PIM that's causing this, so you can stop looking at PIM logs or configuration.
Usually either OPC, or (more likely) MDS are telling NM to shutdown because something isn't valid.
*MOST* likely it's MDS issuing the shutdown command because one of the hostnames you used is:
not resolvable by the hostnames you entered (mrt-icm-prgrb-p, mrt-icm-prgrb-ph) to an IP address
resolvable, but invalid in this context (meaning you entered a valid, pingable address but it's one that's not on this server)
the port is already in use by another process (conflict).
Dump the MDS log & it will tell you exactly why it's issuing the shutdown.
You also asked:
I have one more query, Where does AW stores script and what is the ext of icm scripts.
I want to copy scripts from one aw to another seprate setup.
Scripts are a part of the ICM Configuration database. You cannot just "copy" them from one instance to another. However, within Script Editor, you can do an Export, and then Import the resulting .icms file into the other system. Hopefully all your object mappings are close.
