NSV0: Failed to connect to remote database (11.1.07)
show database verbose gene2 (this is my standby) I get
Error: ORA-16664: unable to receive the result from a database
When I look at the drcgene2.log I see the following message (among others)
NSV0: Failed to connect to remote database gene1. Error is ORA-12514
This seems to be a very clear message except that I am able to sqlplus to gene1 without any issues from a UNIX prompt.
