How Does the MySQL Cluster Manager Help?
Before MySQL Cluster
Manager
• 1 x preliminary check of cluster state
• 8 x ssh commands per server
• 8 x per-process stop commands
• 4 x scp of configuration files (2 x
mgmd & 2 x mysqld)
• 8 x per-process start commands
• 8 x checks for started and re-joined
processes
• 8 x process completion verifications
• 1 x verify completion of the whole
cluster
• Excludes manual editing of each
configuration file
Total: 46 commands -
2.5 hours of attended operation
With MySQL Cluster Manager
upgrade cluster --package=7.1
mycluster;
Total: 1 Command -
Unattended Operation
Results
• Reduces the overhead and
complexity of managing database
clusters
• Reduces the risk of down time
resulting from administrator error
• Automates best practices in
database cluster management
Example: Initiating upgrade from MySQL Cluster 7.0 to 7.2

If You Are Not Using the MySQL Cluster Manager
• You can perform tasks manually, but you have to:
o Issue many commands
o Be present while the process is running
• You can script operations, but:
o Writing scripts takes time
o You need to assign time to test and maintain
scripts
o Scripts add risk and complexity to the system

MySQL Tools
• Graphical and command-line interfaces to your MySQL
databases
• MySQL Enterprise Monitor
o Web application that reduces down time, tightens
security, and increases throughput
o Includes MySQL Query Analyzer
• MySQL Enterprise Backup
• Online “Hot,” non blocking backups
• MySQL Workbench
o Visual database design tool that is used to efficiently
design, manage, and document databases
