Configuring NCR Systems to "share" file systems with Clients
Network Filing Systems, (NFS) is an industry standard utility which enables filing systems physically residing on a host, (server), system to be used by other systems, (clients), connected on the network. Such filing systems will appear to these clients as just another local disk drive.
A typical use for this facility is found on BML Charisma systems. BML use a product called I.Q. as a report generator. I.Q. uses NFS to access the Charisma database.
In each Charisma filing system, there should be a mount point "iqdata".
If iqdata does not exist then create it by entering
mkdir iqdata (CR).
In the home filing system this should be in
/charisma1/bml/iqdata
In subsequent filing systems, i.e. /charisma2 etc. it will be
/charisma2/iqdata
To enable a filing system or a specific file to be mounted on a remote client
edit the file /etc/exports
Add an entry for each filing system which is to be exported, eg.
a) To enable a filing system or file to be available to all nfs clients add entries:
/charisma1/bml/iqdata
/charisma2/iqdata
The above entries will enable these files to be read and written to.
b) To enable a filing system to be available to all nfs clients but to be read only add entries to /etc/exports:-
/charisma1/bml/iqdata -ro
/charisma2/iqdata -ro
After modifying the /etc/exports files you must issue the command
#exportfs -a (CR)
To list exported filing system use the command
#showmount -e (CR)
To show other hosts that have exported filing systems
#showmount -a (CR)
