SOLUTION : 

Check the location of APPLCSF in CONTEXT_FILE

APPLCSF=/a01/<dbSID>/oracle/product/fs_ne/inst/<dbSID_<APPSERVER>/logs/appl/conc/out

APPSERVER[APPOSUSER]_> grep -i APPLCSF $CONTEXT_FILE

         <APPLCSF oa_var="s_applcsf">/a01/<dbSID>/oracle/product/fs_ne/inst/<dbSID_<APPSERVER>/logs/appl/conc/out</APPLCSF>

APPSERVER[APPOSUSER]_>

APPSERVER[APPOSUSER]_> grep -i APPLCSF $APPL_TOP/ARPSYSM2_alpc4khkapm2.env

# APPLCSF is the top-level directory in which the Concurrent Manager

APPLCSF="/a01/<dbSID>/oracle/product/fs_ne/inst/<dbSID_<APPSERVER>/logs/appl/conc/out"

if test "$APPLCSF" != ""

  export APPLCSF

Change APPLCSF path in Application node context file and then in $APPL_TOP/$CONTEXT_NAME.env to the correct path .

execute Autoconfig on App node 

now try to run adadmin again
