Reboot the node:

# shutdown -r now

Repeat all the steps on each node in the cluster.

Determining the LMX traffic for each database

Use the lmxdbstat utility to determine the LMX bandwidth used for database

traffic for each database. The utility is located at /sbin/lmxdbstat.

The utility reports the following information:

■ Status of the LMX protocol

■ The LMX port and buffer traffic received and transmitted at periodic intervals

in packets and kilobytes for each database instance. Specify more than one

database when you want to compare database traffic between multiple

databases.

■ The LMX port and buffer traffic received and transmitted at periodic intervals

in packets and kilobytes for a database process.

Note: LMX statistics collection is disabled when you run the command for the first

time to view the statistics for a specific database instance or database process.

Run the following command to enable LMX statistics collection:

# lmxdbstat -z 1

Since the utility collects the LMX statistics from lmxstat and compiles them for

a database, the total processing time may exceed the reported time. Moreover,

the percentage utilization reported for a database may vary slightly if some

transient Oracle processes consumed LMX bandwidth intermittently along with

the instance-specific processes but did not use it at the time of statistics collection.

For more details on the command, see lmxdbstat (1M).

The format of the command is as follows:

# lmxdbstat [-v] [-?|-h] [-p <pid>] [-d <db1> [<db2>...]] \

[interval [count]]

Where:

Displays a verbose output of LMX traffic over the last 1, 10 and 30

second intervals.
