Example: Configuring the VXFEN Parameters

The following is an example of changing the vxfen_max_delay parameter.

The default file /kernel/drv/vxfen.conf looks like this:

#

# VXFEN configuration file

#

name="vxfen" parent="pseudo" instance=0 dbg_log_size=65536 vxfen_max_delay=60 vxfen_min_delay=1;

Change the min_delay value to 30.

#

# VXFEN configuration file

#

name="vxfen" parent="pseudo" instance=0 dbg_log_size=65536 vxfen_max_delay=60 vxfen_min_delay=30;

Close and save the file. For the changes to take effect, either restart the system, or reconfigure the VXFEN module.

 To reconfigure the VXFEN module

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

   # hagrp -offline oragrp -sys galaxy

2. Stop all Oracle client processes, such as sqlplus, svrmgrl, and gsd, on the node.
3. Unconfigure the VXVFN module:

   # /sbin/vxfenconfig -U

4. Determine the VXFEN module ID:

   # /usr/sbin/modinfo | grep -i vxfen

   The module ID is the number in the first column of the output.

5. Unload the VXFEN module, using the module ID you determined:

   # /usr/sbin/modunload -i module_ID

6. Configure the VXFEN module:

   # /sbin/vxfenconfig -c

7. Bring the service groups back back online:
8. # hagrp -online oragrp -sys galaxy
