how to increase the heap of tomcat

[west timothy]

hai everybody,

we are using TOMCAT(4.1.27).It is throwing 500 Internal Server Error when i am trying to render a large report(128 cloumns*7,200 rows).Please suggest any work around to fix the problem.

with regards,
west

Well you could increase size of the heap Tomcat uses with the -Xmx parameter; just change it in which ever batch file you use to start Tomcat.

A better alternative might be to consider changing how your application is designed to handle large collections of data. 7200 rows is a huge amount of information to render on a web page. If you paginated the results it will be easier to avoid OutOfMemoryExceptions, pluds you would be delivering a easier to read page to the user.
