Using MySQL Toolkit in a HP Serviceguard Cluster Revision README: B.06.00
not be failed over to the adoptive node. To continue monitoring and
turn off maintenance mode, you should remove the "mysql.debug" file.
The user should ensure that the MySQL instance is running properly
before exiting the maintenance phase, since monitoring of the
instance will resume once out of the maintenance phase.
4. RETRY_TIMES=0
This variable is recommended to be set to "0". This will multiply
the SERVICE_RESTART of the MySQL package service (monitor).
For Example: If the package service is set to
SERVICE_RESTART = 2 &
RETRY_TIMES=2
Then actual retries = (SERVICE_RESTART + 1) * RETRY_TIMES.
5. MONITOR_INTERVAL=5 # Seconds.
This is the interval at which hamysql.mon will monitor the process
with PID in the PID_FILE (mysqld parent process).
The time unit granularity is seconds. So, setting
MONITOR_INTERVAL=5 means the parent process is monitored every
5 seconds.
D. Package Configuration File and Control Script
The following steps identify the changes needed to the Serviceguard
package configuration file and control script templates to customize
them for your specific configuration. This information was extracted
from the chapter entitled "Configuring Packages and Their Services"
of the "Managing Serviceguard" manual. For detailed information on
configuring and managing a package, please refer to the "Managing
Serviceguard" manual.
The following parameters are either in the configuration file or
control script as identified below, and must be manually edited for
your unique environment. In the following example, values are
assigned for a package named "mysql_1".
