Now I do not have the status Blocked.

Can anyone let me know why I am not able to connect both the servers at a time?

The issue was I have created giszgg cloned db from orad2. GISZGG and GISDEV are on same server. gisdev was up and running when I did clone and now all the trace files and alert log is getting created by gisdev suffix. Help me out to get solution on this so that GISZGG and GISDEV can run independantly?
