FEI 3 Frequently Asked Questions (FAQ)

1. What does FEI stand for?

   File Exchange Interface. FEI is a kerberized client/server application used to move files between remote sites and a data center (MIPL).

2. How do I check to see if my subscriptions are running?

   Use the UNIX 'ps' utility on the local system your subscriptions should be running on. Typically all MIPS FEI fileTypes start with a project identifier (i.e. m98, cas, ds1, vgr, m01).

   ps -ef | grep "Subscribe m98" (the csh command to list all processes subscribing to m98 fileTypes)

   You can also check the FEI server to see if you are connected using the "Admin" utility. You must know which FEI server you have subscribed to first, so look at your $FEI/feiDomain file:

   cat $FEI/feiDomain | grep fileType

   replace fileType with the fileType you have subscribed to. The line displayed after running this command contains the fileTypeName and the FEI server managing that fileType:

   cat $FEI/feiDomain | grep m98_ops_ssi_edr

   returns

   m98_ops_ssi_edr mipsFEI03

   where m98_ops_ssi_edr is the fileType and mipsFEI03 is the server.

   Now use the Admin utility to show users connected to the mipsFEI03 server:

   Admin mipsFEI03 showusers

   will list ALL users connected to the server, or

   Admin mipsFEI03 showusers | grep principle

   where principle is your kerberos principle used to start the subscription to just see your connection.

3. How do subscriptions get "restarted"? Does the user have to do something or does FEI do it?

   GOOD Question - answer will take alittle time to add, but I'll do it. This is now a place holder so y'all know I got the question and working on the answer. Thanks!

4. What is the difference between FEI V2 and FEI V3?

   another GOOD Question! - answer will take alittle time to add, but I'll do it. This is now a place holder so y'all know I got the question and working on the answer.
