Had a tough one last month when migrating the system to WAS. I’m still new to WAS, hit a few problems and take this chance to document down so that this form my reference and hopefully it help you too.<\/p>\n
Users has been complaining that the web service keep getting time out, returning a 500 error.<\/p>\n
What i found out was that i can actually, tune the “ServerIOTimeout” parameter in the WAS plugin for Apache beyond the default. i used 900, which is 15min in seconds.<\/p>\n
In addition,a little performance fine tuning was done using “LoadBalanceWeight” to keep the application servers from being ‘hit’ random when they are just started up, especially when i have a cluster of them. As recommended by IBM specialist, i used some numbers, with one of the application server assigned to an odd number, different from the rest.<\/p>\n
The idea is to make one of the application server the first one to serve, instead of randomising it.<\/p>\n
Server CloneID=”179d3la” ConnectTimeout=”5″ ExtendedHandshake=”false” LoadBalanceWeight=”20″ MaxConnections=”-1″ Name=”Node1″ ServerIOTimeout=”900″ WaitForContinue=”false”
\n…

\n Server CloneID=”179d5sb” ConnectTimeout=”5″ ExtendedHandshake=”false” LoadBalanceWeight=”20″ MaxConnections=”-1″ Name=”Node2″ ServerIOTimeout=”900″ WaitForContinue=”false”

\n Server CloneID=”179d8gc” ConnectTimeout=”5″ ExtendedHandshake=”false” LoadBalanceWeight=”21″ MaxConnections=”-1″ Name=”Node3″ ServerIOTimeout=”900″ WaitForContinue=”false”

Do let me know if you have better ideas of solving it.<\/p>\n","protected":false},"excerpt":{"rendered":"
