[U2] SANs and U2 performance
Hi Steve, When you do have the time, could you enlighten us and/or point us to some resources on the subject of SAN tuning for U2? We upgraded our UD system to new Alpha servers and an HP SAN last summer, and it runs 5 times faster on the new hardware, so everybody's happy. But now I'm curious if we can do even better. My simple pre-upgrade calculation based on SCSI (old) vs. fibre-channel (new) bus speeds suggested the potential to run 10 times faster. Thanks, Tom Derwin [EMAIL PROTECTED] 01/21/07 10:50 AM snip Also, I will reiterate again, U2 Lab Services are not fans of SANs. The reason is the defaults and assumptions can really mess up a U2 shop. I'm not going to go there, for I don't have the time. Thanks! Steve Stephen M.

Re: [U2] Microdata Conversion
Have you considered upgrading to the current Reality (v12) from Northgate-IS? There should be no conversion at all. You will need to buy licenses, of course, but it will run on anything, so there will be minimal hardware expense.

I believe that UD has a conversion utility to adjust the 10 line dict items to the 7 line ones. I am looking forward to being the main programmer with the conversions. I am not looking to farm out this project as it will get too expensive real fast.

Re: [U2] Orphan record locks
Hi Noah, When a PC crashes, the telnet client isn't able to tell the UD server to terminate the session, so the telnet process on the server just sits and waits. As you discovered, the server process will hold any locks it has set until its Unix PID is killed. Couple of solutions (we use both) are: 1) Enable an inactivity timeout for user sessions with the TIMEOUT command as part of the login routine (VOC LOGIN). This will automatically log off a telnet session after the number of minutes of inactivity you specify. 2) Run the LIST.READU command periodically. It will show you when a record lock was set and the Unix PID of that session, so you can manually kill the session if it's client-less. Try plain old kill first, a few times if needed. Save kill -9 as a last resort. Hope this helps, Tom Derwin Wally Terhune 01/19/07 3:35 PM snip The udt process holding these locks is likely still alive. If the process is killed with a hard signal (like -9), the UniData cleanupd and smm processes work together to release locks and licenses for the process that has disappeared from the system. snip Wally Terhune U2 Support Architect IBM Information Management Noah Hart 01/19/07 12:48 PM CONFIGURATION: Unidata 6.1; Solaris 5.7 BACKGROUND: Last week I noticed that a process had been holding a readlock for 4 days. The operator was no longed logged into our application, and told me that last week her computer crashed. I called our application software provider, and was told that when a U2 telnet session is terminated while a process holds a read lock, the lock is not released. QUESTION: Is this true? Is there any way to change this behavoir.
