Hallo,

Ich brauche dringend Hilfe wir haben ständig Probleme bei der Performance mit der Maxdb

Ich verstehe nicht wie ich die MaxDB dazu kriege dass diese schneller wird.

kann sich das wer anschauen von Euch Profis und mal sagen was pauschal schon mal dieses "isolated index " beheben kann.

Ich würde erstmal in der ST02 gucken wie die Speicherauslastung/Hitratio ist und gegebenfalls die Parameter dann in der RZ10 anpassen.

Ich kann hier jetzt nix erkennen was irgendwie super schlecht wäre. Im Gegenteil. Man darf mich aber gerne berichtigen.

Wie äußert sich denn die schlechte Performance? Oft ist das Problem auch einfach der Anwender, der einfach vernüftiger Arbeiten sollte. Gerade wenn es um völlig abenteuerliche Selektionen von irgendwas geht.

Hallo,

Danke,

also sollte ich vielleicht doch woanders die Performance Probleme suchen.

Ich halte es generell für ne gute Idee das System über einen längeren Zeitraum zu beobachten.

Hilfreich sind u.a. die Transaktionen

- ST02

- SM04

- SM50

- ST03N

- SM37

So lassen sich prima Störer im System verlässlich aufspüren. Das kann ein Simpler Job tagsüber sein welcher das ganze System ausbremst. Oder eben ein Anwender, welcher nicht sauber selektiert.

Die verbaute Hardware ist natürlich auch noch ein Thema. Ebenso die Anbindung. Gibt also verschiedenste Punkte wo man ansetzen kann.

Benutzer, die gerade dieses Thema lesen
