Just a reminder; if you are starting Spectrum from commandline on the Secondary, make sure to pass --secondary $SPECROOT/bin/startSS.pl --secondary
If you run startSS without that parameter, it will first start ArchMgr. Bad juju on a secondary SS.

The Event tabe stores every event with all information (including modelhandle) for the configured MAX_EVENT_DAYS. The statistical table contained data for the attributes and you could create reports on the data using the legacy Report Generator. Currently no statisical data is logged by default and I think Report Generator is no longer part of the product (definitely not in 9.0). This has been dropped in favor of SRG (and eHealth). The performance tap data is live polled and only temporarily stored in OC. 2) Decreasing the max event days will purge data beginning with the oldes data. It is a slow process. to reduce the database size you need to run additonally the maintenance and optimize scripts. 3) No. On the contrary - it will cause problems if Archive Manager (ArchMgr) is running on both primary and secondary (at least with the same precedence). It might be possible with different precedences, but if the "primary" ArchMgr comes up again - you have lost the data for the time it was down. This data would be stored in the "secondary" and there is now way to synch it up. Well you probably could do manually if you are good with SQL. However - no need to do it. If the ArchMgr is down the active SS stores the events in its SSdb ("locally stored events") once ArchMgr is back the events are written back. If you have an problem where both primary SS and your ArchMgr are down - make sure you start the ArchMgr first, wait untill the "locally stored Events" are zero before starting the primary server again. Otherwise you will loose the events wich are stored in the secondary servers SSdb. Hope that helps!

"Kuta Pavel" <[EMAIL PROTECTED]> To 18.09.2008 14:19 "spectrum" <[email protected]> cc Please respond to "Kuta Pavel" Subject <[EMAIL PROTECTED]> [spectrum] DDM question Hello all, I would like to check if we same understand couple of things with DDM. 1) Statistcial and Events> Event Data - All events are stored in database -> OK this means only events with their HEXA codes and count of them and relations to models? Statistical - Which statistical data are stored? Just only online "Performance Tab Info" ? Or is something more behind? How is it stored if "statistical" data should be "online" ? could u please help with better explaination? 2) In case of change MAX_xxxx_DAYS to less number than it was -> Will it cause after next run of ArchiveManager automaticel purge of older data? Or it is valid only for new saved events? Would it be better to offline reduce (delete) stats data before change values? 3) LANDSCAPE_PRECEDENCE in .configrc Regarding documentation I understand that also (not only SS) Archive Manager could running in HOT STANDBAY mode. Have u ever tried (or implemented) this scenarion? Experience/Problems? How are events handled? Are in both databases the same? Or take over means only for new (after 10 precedence down)? thannks lot for any shared experience..
