Configuring the VXFEN Parameters
For the parameter changes to take effect, reconfigure the VXFEN module using the following steps:
-
Shut down all Oracle service groups on the node:
# hagrp -offline oragrp -sys galaxy
-
Stop all Oracle client processes, such as sqlplus, svrmgrl, and gsd, on the node.
-
Unconfigure the VXVFN module:
# /sbin/vxfenconfig -U
-
Unload the module:
# /usr/sbin/kcmodule vxfen=unused
-
Configure the tunable parameter:
# /usr/sbin/kctune tunable=value
For example:
# /usr/sbin/kctune vxfen_debug_sz=65536
-
Start the VXFEN module:
# /sbin/init.d/vxfen start
-
Bring the service groups online:
# hagrp -online oragrp -sys galaxy
