Follow these instructions to shut down fileshare in the background.

Do not stop Fileshare with kill -9.

You can write a COBOL program which calls the Fileshare Manager (Call "fsmgr" using ...) with function code 4.

The Fileshare Manager program supports the following  function-codes:

1 = Backup recovery log file
2 = Close all open data files
3 = Log off all connected clients
4 = Shut down Fileshare
5 = Shut down and re-start Fileshare
 

Alternatively you can run the utility fsclose using "cobrun fsclose".

FileShare is running as a service using sample FS.CFG located in the Windows\\system32 directory
Using CCI.INI to set the PORT number.
FS.CFG sample
/s FSNAME
/cm ccitcp
/d ?:\\databse-reference-file
/pf ?:\\password-file
/wd ?:\\filehare-working-directory-path
/sc

CCI.INI file contains
[ccitcp-servers]
FSNAME:MFPORT:12003

[ccitcp-targets]
FSNAME=MFNODE:machine-name-or-IPAdress,MFPORT=12003
