I provide more info. If I login as user1 and "su" to oracle. Error message is:

$ su - oracle Password: su: cannot set user id: Resource temporarily unavailable

Does oracle allow a user login? Sounds like its shell is nologin.

ssh oracle@ora10 oracle@ora10's password: Read from remote host ora10: Connection reset by peer Connection to ora10 closed.

I have not problem login as "root" or other users.

Is it possible too many processes run by "oracle" and don't allow me login.

I check server current have 2000 oracle processes running.

$ ps -ef|grep oracle|wc -l 2000

anyone know how to fix this issue?

Thanks. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

very possible this problem cause by /etc/security/limits.conf.

the entry are:

oracle soft nproc 2047 oracle hard nproc 16384

ps -ef|grep oracle|wc -l is 2000. Very close to 2047.

Can I increase number to 3000 or more?

If I increase number on limits.conf, do I need reboot to make it affect?

Thanks.

Does that user have a working shell?   Do you want it to?
