Hello All,
Max Heap size of j2ee web dispatcher for our DEV BI 7.0 is 1024 MB.But our QA BI 7.0 system is 130 MB.I need to know in which sceanario we increase Max Heap size of j2ee web dispatcher??For BI 7.0 what should be the perfect heap size??
Ashley,

It really depends on how much memory is available on your systems? There are two parameters -Xms (initial heap size) and -Xmx ( max heap size) which you can tune for performance. Remember Xms plays important role in garbage collection cycle and time. If you decide to increase then increase gradually. BTW, you have to use config tool for these parameter changes.
Have a look at following link.

Where are her heap? If you say aboy dispatcher nodes in AS JAVA, when it is not "web dispatcher"

You should be ok to set max heap size to 1024 MB since you have 16GB of RAM in your system.
where you read abot it ? Per same Note 723909 - Java VM settings for J2EE 6.40/7.0 -->
For dispatcher nodes it's sufficient to set the heap size to 171m on 32 bit and to 256m on 64 bit platforms. There is no need to apply the parameters mentioned under 4-9 below.
