UVODBC/OleDB job Randomly hang
I have a client running AIX, UniVerse 9.5.1.1 and UVODBC 3.7 which they are connecting to via .NET / OleDB. They see occasional hangs from their DataReader and consequently, kill their process and reissue a query. Now we are seeing some hangs on the UniVerse side such that UniVerse performance is greatly degraded and interactive users cannot log in. When this happens, they have been forced to restart UniVerse. They have a uvodbc user set up that is called via the .NET calls. Most of the processes are owned by the user uvodbc, however, the common thread is that there are a number that are owned by root. They are the processes that tend to be the ones that hang about especially when the system slows down. Has anyone seen this sort of behavior, any suggestions?

RE: Performance
I saw /tmp mentioned in one of Scott Richardson's posts. UniVerse uses /tmp for building select lists and sorts. If it is undersized, it can cause page faults like you are seeing. How big is /tmp? It might pay to monitor it's usage. It can be as critical as having adequate swap / paging space. Double check Scott's recommendation on /tmp.

Application files have all been analyzed and sized correctly. 2.) IBM U2 support analyzed Universe files, locking, swap space and all have been adjusted accordingly or were 'ok'. 3.) We are running RAID 5, with 8G allocated for Universe 4.) We are already running nmon, which is how we identified the paging faults and high disk I/O 4.) Attached you will find the following: smat -s LIST.READU EVERY PORT.STATUS Uvconfig Nmon (verbose and disk) Vmtune I know this is a lot of data, but it is a mix of what each of you have suggested. Thanks again for all of the help.

We are running UV 10.0.14 on AIX 5.1.we are having terrible 'latency' within the application. This is a recent conversion from D3 to UV and our client is extremely disappointed with the performance. We've had IBM hardware support and Universe support in on the box, but to no avail..we are seeing high paging faults and very highly utilized disk space. Any thoughts or suggestions?

[UV] ODBC / OleDB server logging
I have searched high and low, and have found many references to UniVerse ODBC / OleDB server logging, where to find logs, etc. but I fail to find how to turn on logging on Unix under UniVerse 9.5.1.1 (or higher). I would imagine since this is Unix, there is somewhere a -d or -v is used on uvosrv or some other binary. The second piece is when logging gets turned on, is there a way to tell how long a query took on the server so we can compare that with the query time on the server?
