Reconfiguring the LMX module
This section discusses how to reconfigure the LMX module on a node. In this example, configuring contexts=16384 allows a maximum of 8192 Oracle processes (8192 * 2 = 16384). Note in the following output that double-quotes are not used to specify an integer value.
# # LMX configuration file # name="lmx" parent="pseudo" contexts=16384 instance=0;
For the changes in the /kernel/drv/lmx.conf file to take effect, either restart the system or reconfigure the LMX module as described in the following procedure.
To reconfigure the LMX modules
- Shut down all Oracle service groups on the system:
# hagrp -offline oragrp -sys sys1
- Stop all Oracle client processes on the system, such as sqlplus and svrmgrl.
- Unconfigure the LMX module:
# lmxconfig -U
- Determine the LMX module ID:
# modinfo | grep -i lmx
The module ID is the number in the first column of the output.
- Unload the LMX module, using the module ID you determined:
# modunload -i module_ID
For systems running Solaris 11, run the update_drv command to re-read the
/kernel/drv/lmx.conffile.# update_drv lmx
- Configure the LMX module:
# lmxconfig -c
- Bring the service groups back online:
# hagrp -online oragrp -sys sys1
