Any ideas would be gratefully appreciated.
I have put the correct JDK on - 1.6
and also 10.3.2 Web logic.

Answer 1

Many thanks for the response however I tried to re-instll my grid control after the process of installing the weblogic and it still fails to recognise the ports.
I have greapped for all port ranges for the EM Upload port:
[root@dc1-eng-poem01 ~]# netstat -an | grep 5556
[root@dc1-eng-poem01 ~]# netstat -an | grep 48890
[root@dc1-eng-poem01 ~]# netstat -an | grep 4890
[root@dc1-eng-poem01 ~]# netstat -an | grep 4889
[root@dc1-eng-poem01 ~]# netstat -an | grep 4891
[root@dc1-eng-poem01 ~]# netstat -an | grep 4892
[root@dc1-eng-poem01 ~]# netstat -an | grep 4893
[root@dc1-eng-poem01 ~]# netstat -an | grep 4894
[root@dc1-eng-poem01 ~]# netstat -an | grep 4895
[root@dc1-eng-poem01 ~]# netstat -an | grep 4896
[root@dc1-eng-poem01 ~]# netstat -an | grep 4897
[root@dc1-eng-poem01 ~]# netstat -an | grep 4898
[root@dc1-eng-poem01 ~]# netstat -an | grep 4899
and no results - yet the port is defaulting to -1 (I am not familair with node manager) Can i bounce the box shutting down weblogic and then try install with weblogic down - or does this need to be active during the install?
Many thanks,
Ric
