[JBoss Portal] - IPC & Page Communication
by jayakarteek
Hi,
IâÂÂm currently evaluating JBoss portal application. In my requirement, IâÂÂve 2 portal pages say Page-A and Page-B and both has few portlets inside.
There is a Menu portlet which has few Hyberlinks. It is added in both Page-A and Page-B at Left region like a Quick links for the application. My requirements are
1) when I select a hyper link from Page-A (Menu portlet), I need to refresh the portal screen with Page-B, also i need to send some parameters between pages through portlets.
2) Can selected portlet in page-B Mode(Maximized, minimized,Normal) can be modified though hyper links.
I guess it is a simple work but IâÂÂm currently lacking with information. Could you please anyone provide me the proper documentation or sample code to understand the functionality.
Thanks and regards,
Jaya Karteek.

[Management, JMX/JBoss] - Re: SchedulableMBean arguments

np. ur welcome.
JbossCache doesn't exclude the use of a database. The question is... the exact use of each. For example, database can be used only for persistence in case of a general power failure or system restart, but not for failover. Don't forget that if you use a non High Availability clustered database, then you still have a 1-point failure node. If your db server crashes, then so does all your system.
Let me search a little bit this weekend to refresh my memory and I ll send you whatever info i believe you ll find useful. In the meantime, check the url I posted previously and tell me what exactly is the purpose of your job scheduling app? To be accurate, to handle vast number of schedules, to be lossless? To execute many small jobs or fewer cpu-memory hungry jobs? You need clustering for High Availability or Load Balancing or both? I am asking these because I didn't find a do-it all in one solution :) For example if you use synchronized cache, and as every node added to the cluster brings a hell of a lot network traffic for cache synchronization, the bottleneck appears to be the network and not the Timer itself.
