MySQL1/mysqld.pid
NOTE: mysqld_safe was previously called safe_mysqld. For an older version of MySQL,
the user must modify suitable sections in the my.cnf file.
To run MySQL toolkit with the older versions of the MySQL follow these steps:
1. Create a soft link named “mysqld_safe" in the MySQL installation directory/usr/bin for RH
to point to "safe_mysqld".
CMD> ln -s /usr/bin/mysqld_safe /usr/bin/safe_mysqld
2. Grant permission to run the newly created link:
CMD> chmod 755 mysqld_safe
The following sections in this chapter describe the legacy mode of Serviceguard packages. For
information on creating the Serviceguard package using the modular method, see the whitepaper

Toolkit configuration file(hamysql.conf)
All configuration variables for the toolkit user are stored in the file - hamysql.conf, in Shell script
format. Table 18 (page 92) lists the user variables and sample values in the file.
Table 18 User Variables in hamysql.conf file
DescriptionFile name
Only one of the two variables (either CONFIGURATION_FILE_PATH
or DATA_DIRECTORY) must be defined. If both are defined,
CONFIGURATION_FILE_PATH="/MySQL_1/mysql/my.cnf"
or DATA_DIRECTORY="/MySQL_1/mysql"
CONFIGURATION_FILE_PATH is used and DATA_DIRECTORY is
ignored.
NOTE: If DATA_DIRECTORY is used, my.cnf must reside in the
DATA_DIRECTORY location. This directory is also used as the data
directory for this instance of the database server.
This is the path where PID file for the MySQL daemon is created for
the parent PID. If this variable is defined, it overrides the "pid-file"
PID_FILE="/var/run/mysql/mysqld.pid"
defined in the MySQL configuration file my.cnf. The PID identified
in this file is monitored by the toolkit monitor, "hamysql.mon".
