Example: Configuring LMX Parameters

If you see the message "no minors available" on one node, you can edit the file /etc/sysconfig/lmx and add a configuration parameter increasing the value for the maximum number of contexts. Be aware that increasing the number of contexts on a system has some impact on the resources of that system.

In the following example, configuring contexts=16384 allows a maximum of 8192 Oracle processes (8192 * 2 = 16384). Note that double-quotes are not used to specify an integer value.

#

# LMX configuration file

#

# Maximum number of contexts allowed

LMX_MINORS_MAX=16384

For the changes to take effect, either reboot the system, or reconfigure the LMX module.

 To reconfigure the LMX module

1. Shut down all Oracle service groups on the system:

   # hagrp -offline oragrp -sys galaxy

2. Stop all Oracle client processes on the system, such as sqlplus and svrmgrl.
3. Unconfigure the LMX module:

   # /etc/init.d/lmx stop

4. Configure the LMX module:

   # /etc/init.d/lmx start

5. Bring the service groups back online:

   # hagrp -online oragrp -sys galaxy
