Limiting Maximum Number of Processes Available for the Oracle User

To see the current limit of the maximum number of processes for the oracle user, run:

$ su - oracle

$ ulimit -u

Note

The ulimit options are different for other shells.

To change the "soft" and "hard" limits for the maximum number of processes for the oracle user, add

the following lines to the /etc/security/limits.conf file:

oracle soft nproc 2047

oracle hard nproc 16384

To make this change permanent, you could add "ulimit -u 16384",for bash, to the

~oracle/.bash_profile file which is the user start up file for the bash shell on Red Hat Enterprise

Linux (to verify your shell execute echo $SHELL). To do this you could simply copy and paste the

following commands for oracle's bash shell:

su - oracle

cat >> ~oracle/.bash_profile << EOF

ulimit -u 16384

EOF

To make the above changes permanent, you could also set the soft limit equal to the hard limit in /

etc/security/limits.conf:

oracle soft nproc 16384

oracle hard nproc 16384
