ERROR WHILE TO ESTABLISH APPLICATION FILE SERVER CONNECTION (ID 117012.1)

Cause : TNS Listener is Down on node or Network Related Issue


1. Check your listener status 
$ps -ef | grep tnslsnr
$ps -ef |grep FNDFS

If it is down you can start from using adalnctl.sh apps/****

2. Check actual Machine name for the concurrent process server are same 
$uname -n
Check from Application System Administrator > concurrent > manager > Administer Responsibility
hope its same if not same then follow below steps

Stop concurrent manager and update FND table
$OAD_TOP/admin/scripts/adcmctl.sh apps/apps stop

Check Machine info

SQL > select target_node from FND_CONCURRENT_QUEUES;

Here is the problem , this contents old machine name , just update the new machine name here.

SQL> update_set '<newmachinename>' where '<oldmachinename>';

SQL> commit;;;;

SQL >start

3. Check TNSNAME.ora file , Have valid entry of FNDFS_<hostname>
     If not entry then first take the backup of tnsfile.ora and modify
And check its ping or not
$ tnsping FNDFS_<hostname>

In our case its works , now file server connection properly

---
Next scenario : You have applied patch , And getting error FNDFS was not relink or missing 
Solution :

Stop FNDFS
$OAD_TOP/admin/scripts/adalnctl stop apps/apps

Backup the current FNDFS before relinking
$ mv FNDFS FNDFS.bkp

Relink 
$  adrelink.sh force=y 'FNDFS'

Start
$ OAD_TOP/admin/scripts/adalnctl start apps/apps
