[CentOS] can not login to server (use ssh)

[mcclnx mcc]

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.
