R12.1.x ASCP : The executable file /../../bin/MSCMON for this concurrent program cannot be executed. Contact your system administrator or support representative.

We are in the process of implementing Advanced Supply Chain Planning (ASCP) for our Oracle E-Business Suite (EBS).  The Snapshot Monitor program (MSCMON) resulted in the below error.

Error:
The executable file /p01/oracle/apps/apps_st/appl/msc/12.0.0/bin/MSCMON for this concurrent program cannot be executed. Contact your system administrator or support representative. Verify that the execution path to the executable.

Operating System: Linux x86-64 bit
EBS Version: R12.1.2 with ASCP patches R12.1.3

Issue: Some of the executable were missing like MSCCPP, MSCMON, MSCNEW, MSCNSP, MSCNSPNM, MSCPCL, MSCPCP, MSCPDW, MSCPRG, MSCSDW, MSCSLD and MSCXGCAL from $MSC_TOP/bin. MSONEW was missing from $MSO_TOP/bin.

Solution:
Relink the MSC and MSO modules using adadmin and verify the executable are present.

ADADMIN
 - 2. Maintain Applications Files menu
    - 1. Relink Applications programs
       Do you wish to proceed with the relink [Yes] ?
       Enter the name of your Oracle Applications environment file below.
       File name [APPLE_vaidiyan1.env] :
       Enter list of products to link ('all' for all products) [all] : MSC
       Generate specific executables for each selected product [No] ? Yes
       Relink with debug information [No] ?
       Enter executables to relink, or enter 'all' [all] :

Repeat the same process for MSO.

In my case, adrelink failed for the MSC executables.

Error:

Relink Solution:

This is a Bug 9907575: CHANGE ADRELINKNEW.SH FOR RELINK APS EXE ON OEL/RH 5.

1. Backup $AD_TOP/bin/adrelinknew.sh and open the file.
2. Search the string below in the LINUX section and modify it appropriately

CPP_LDFLAGS=' -L$(ORACLE_HOME)/lib -L$(ORACLE_HOME)/lib/stubs -lclntsh'
 
TO

CPP_LDFLAGS=' -L$(ORACLE_HOME)/lib -L$(ORACLE_HOME)/lib/stubs -lclntsh -Wl,--noinhibit-exec' 

3. Now relink MSC/MSO/MSR executables with adadmin.
