Hi All (For WLS 5.1 not on WLS 6.x) When starting the server on Cluster env should I have start scrip (startWeblogic.sh) for all the server. Currently I have three servers (server11,server12,server13) under cluster. So my question is. should I use start11.sh, start12.sh and start13.sh to start each server and command option will be like this in the each startServer1x.sh file... weblogic.system.name=server1x weblogic.cluster.name=mycluster weblogic.cluster.enable=true Should I also need to start one AdminServer and rest servers as we do in WLS6.x Please share your idea. Thanks
