su: cannot set user id: Resource temporarily unavailable
Hi there,
I’m getting following error when I use root to “su – oracle” in Linux. Finally, I found the solution as shown below 🙂
# uname -srm
Linux 2.6.18-308.11.1.el5 x86_64
# su – oracle
su: cannot set user id: Resource temporarily unavailable
# ps -eLF | grep “^oracle” | wc -l
2068
Increase value “nproc soft limit” for oracle:
#– /etc/security/limits.conf –#
#oracle soft nproc 2047
oracle soft nproc 4095
# su – oracle
$ whoami
oracle
