Problem Statement:
When attempting to start concurrent manager then none of the concurrent manager is starting and Internal manager creates a zero byte log file. There is no error displayed while starting the concurrent manager.

Actual Process = Target Process = 0 ( For Every Concurrent Manager )

Cause:
Executable "sh" is not pointing to the correct "sh".

$FND_TOP/bin/sh
It should point to operating system "sh".

1.) Connect to appsTier : Concurrent Manager Node
$ chmod 644 $FND_TOP/bin/sh
