Heh – just ran into an all-too-familiar “duuh” situation. I was launching DBCA to update a few settings on some services in a test database and it was taking …f…o…r…e…v…e…r… to run.
It must have spent a minute on this partially updated screen. Now I haven’t launched DBCA in a week or so on this machine… and it is a vmware-based test cluster so it’s a bit slow anyway… but this just seemed excessive.
So I jumped into another window and typed “ps” to see what running. Lo and behold, here’s what I see:

Duuh!! This just arose from the common practice of putting a password on the ssh key when configuring host equivalence. Of course this is what you should be doing; it’s a best practice and it’s even spelled out in the RAC install guide… but it’s easy to forget that once you set it up you have to enable user equivalency before running DBCA anytime at all. Not just an install-time thing. I’m sure a few people will find sneaky ways to integrate it into their login scripts but that isn’t a good general practice.
Naturally, as soon as I enabled the host equavalence everything was back to normal.
[oracle@rh4lab15 ~]$ exec ssh-agent $SHELL [oracle@rh4lab15 ~]$ ssh-add Enter passphrase for /u10/app/oracle/.ssh/id_rsa: Identity added: /u10/app/oracle/.ssh/id_rsa (/u10/app/oracle/.ssh/id_rsa) Identity added: /u10/app/oracle/.ssh/id_dsa (/u10/app/oracle/.ssh/id_dsa) [oracle@rh4lab15 ~]$ dbca
I know this is kinda obvious but I thought I’d post it anyway. Hope it helps some googler someday. :)
Thanks, I just needed that.
Hopefully I’ll remember this if I ever graduate to a RAC environment. I’ve never seen the “f” parameter to “ps” before, that makes the output sexy. Although I usually end up grepping “ps auwx” output anyway, so the formatting would probably lose something in the translation.
Hi ,Thx it solved my problem ..
