If your WebSphere Servers are taking too long to start up you can try enabling “Start components as needed” from the Admin Console as shown below.

I got a 20% decrease in time once I enabled this on my WebSphere Portal Server but your mileage may vary .. :-)

WebSphere has the concept of DMGR, short for Deployment Manager that is very similar to Administration Server in WebLogic that serves as the main Administrative point. My requirement is to write a JMX monitoring application that will attach to the DMGR and monitor all the instances in the Cell (~ domain in WebLogic). In WebLogic this can be easily achieved by writing a StartupClass and deploying it to the Administration Server. In WebSphere this is not that straight forward since WebSphere does not allow you to deploy anything to DMGR.
The closest I found is CustomService. CustomService will allow you to run your piece of code inside the JVM during Startup or Shutdown. IBM discourages you running this in DMGR (I am not sure why), but this serves my purpose perfectly since I can get to all the MBeans from DMGR with ease .. :-)
