Regarding IBM websphere number of applications deployed and issues

Hi,

We have IBM websphere server with around 60 small applications installed on it. As per our process, users can upload document sets in form of small applications on this server. Earlier this number was small but now as users have increased these number of applications are increasing on server and its not working properly. Some of the applications gets down frequently even if their status is green in server console. After restarting these apps it works fine.

Thing i am not getting is, Is there any limitation on number of applications deployed on server? How can i fix or tune this. Frequently we need to restart server.


Regards, Vijay Jamadade.

Just want to correct. Its 115 applications but those are small. Sometimes it crashes with heap issues. Any suggestions?

Increased load might obviously put bigger strain on your server resources, including memory.

Are all errors you encounter caused by heap issues? If not, what are the other issues?

Hi, You have deployment antipattern.

Because your functionality is EJB or WebApplication or RAR than you can group it into countable number of EARs.
Big number of application increasing deployment and restart time.

we are going to try one more option of adding space on this machine. It might improve things. But we are also thinking of grouping of applications in ear as suggested by Anton.
 
It is sorta covered in the JavaRanch Style Guide.
