= Increase Heap Size =

== Application Server == 

# in Websphere admin console, 
# go to '''Servers''' section -> '''Server Types''' -> '''Websphere Applicaton Servers''' -> [MXServer] 
# go to '''Java Process Management''' (link on the right side menu) -> '''Process Definition''' -> '''Java Virtual Machine'''. 
# Set both '''Initial''' and '''Maximum''' heap size to 6144 MB (Production)

== Dmgr  == 

# in Websphere admin console, 
# go to '''System Administration''' section (on the left side menu) -> '''Deployment manager'''
# go to '''Java Process Management''' (link on the right side menu) -> '''Process Definition''' -> '''Java Virtual Machine'''. 
# Set both '''Initial''' and '''Maximum''' heap size to 2048 MB (Production)

== WAS Admin console ==

# edit the '''wsadmin.bat|sh''' under '''/opt/IBM/Websphere/AppServer/bin'''
