I'm surprised it ever works... why are there spaces between the directory name and the script name? Try making it like this:
Code:
#!/bin/bash
/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/bin/startManager.sh
/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/startNode.sh
/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/startServer.sh server1
/opt/IBM/HTTPServer/bin/apachectl start
