From Chris.Bowes@kosa.com Thu, 24 May 2001 12:18:33 -0700 From: "Bowes, Chris" Date: Thu, 24 May 2001 12:18:33 -0700 Subject: RE: Maximo Message-ID: MIME-Version: 1.0 Content-Type: text/plain Title: RE: Maximo Hi James,        No we didn't use MTS.  We were on an NT server and it seemed to do a lot better when we analyzed everything using compute stats and analyzing all indexed columns and setting up histograms for it.  Also check all the indexes and their columns, we ran into a lot of them that were just crazy.  On several tables the change number field was indexed.  It's not used in any queries, but it was indexed.  There were indexes on change dates.  Then there were things like the workorder number not being indexed in some of the tables for the workorder module.  It was absurd.  I hope the newer versions are better as I'll be going back to them soon.  If I can think of anything else, I'll let you know.   HTH. --Chris Chris.Bowes@Kosa.com   -----Original Message-----From: James Xing [mailto:james.xing@merc-tech-grp.com]Sent: Thursday, May 24, 2001 1:37 PMTo: Multiple recipients of list ORACLE-LSubject: RE: Maximo Thanks Chris, Did you turn on MTS on your production server? Is that recommended? In our environment, the system was fine on dev server which is not using MTS, another DBA who is in charge of production server turned MTS on and found the performance is 4 times slower.     James -----Original Message-----From: root@fatcity.com [mailto:root@fatcity.com]On Behalf Of Bowes, ChrisSent: Wednesday, May 23, 2001 8:28 AMTo: Multiple recipients of list ORACLE-LSubject: RE: Maximo ON all the maximo installations I have done, the biggest problems have been with maxencrypt a table that holds the encrypted key that allows everyone in the base.  There is a script that will reset this if the users cannot get into the system.   Make sure that the character set in the client is set to the same as the base.  If users cannot get into the base due to bad password and you *know* the user/password are correct, then something happened to the maxencrypt and/or the character sets are not the same.  I am hoping that 4i eliminates that table, but since I haven't seen it, I don't know if it does. I don't know about the current version, but when I worked with it about a year ago, the indexes were terrible.  We dropped and created a number of indexes to improve things.  We used cost base optimization (oracle v7 at the time) and and a job that analyzed every couple weeks on the big tables and every month on the others. If you have to do an import of the base, you will need to run the maxora??.sql script that creates a couple views under sys.  I am sorry that I cannot remember the script at this moment.   I'll check with some of my old comrades and see if they can remember it.  If you're moving to production, you probably have all the columns defined and sized.  If not, sometimes the column changes do not get registered in the maxsyscols table and you'll need to update it. Otherwise, the system really does quite well once it is running.  If I can think of anything else I'll re-reply. --Chris Chris.Bowes@Kosa.com -----Original Message----- From: James Xing [mailto:james.xing@merc-tech-grp.com] Sent: Tuesday, May 22, 2001 6:15 PM To: Multiple recipients of list ORACLE-L Subject: Maximo Hi Group, I have a Maximo system moving into production, using Oracle 816/Sun solaris If anyone has experience, from DBA point of view, what I should be care of? anything to change/check? any particular table?
