Shared configuration
The configuration and database files are placed on shared disks, accessible to all the nodes. Since
the storage is shared, you need not ensure that all the nodes have the same configuration.
Multiple instance configuration
MySQL database server supports multiple DB instances running on the same node. Using this
toolkit, you can configure multiple MySQL toolkit packages to run on the same node. One copy
of the toolkit can serve one package. So, to configure multiple packages, you must create separate
directories, one per package, and configure each package to run a unique database instance.
Using MySQL toolkit
After installing the MySQL toolkit, you can use this toolkit to:
• Configure packages in an SG/LX environment
• Manage packages
For more information about managing packages, see Managing packages. (page 35)
