Portal 7 - tuning guide ( Hints & tips )

53 Views

Hi team,

We are busy preparing to upgrade our Production Portal from EP6 to EP7, and I require some info regarding the memory settings for the dispatcher & Server.

Still not too sure if the current settings will be OK. (too high or low )

We are currently running on Solaris 10 & Oracle 10g.

We will have 1 DB server and 3 apps server for the Portal.

Below are the settings for the Dispatcher & Server on the Q/A system:

Please advise if these will be fine for the Production system.
