A successful deployment depends on being mindful during deployment, operations and ongoing maintenance.
Identify the best deployment method for your environment and use that
in production and testing. See
Section 10.1, “Comparing Staging and
Standardize the OS and database prerequisites. There are Puppet and Chef modules available for immediate use or as a template for modifications.
For security purposes you should ensure that you secure the following areas of your deployment:
Ensure that you create a unique installation and deployment user, such as tungsten, and set the correct file permissions on installed directories. See Section C.3.3, “Directory Locations and Configuration”.
When using ssh and/or SSL, ensure that the ssh key or certificates are suitably protected. See Section C.3.2.2, “SSH Configuration”.
Use a firewall, such as iptables to protect the network ports that you need to use. The best solution is to ensure that only known hosts can connect to the required ports for Tungsten Replicator. For more information on the network ports required for Tungsten Replicator operation, see Section C.3.2.1, “Network Ports”.
If possible, use authentication and SSL connectivity between hosts to protext your data and authorisation for the tools used in your deployment.
See Section 7.5, “Deployment Security” for more information.
Choose your topology from the deployment section and verify the configuration matches the basic settings. Additional settings may be included for custom features but the basics are needed to ensure proper operation. If your configuration is not listed or does not match our documented settings; we cannot guarantee correct operation.
Make sure you know the structure of the Tungsten Replicator home directory and how to initialize your environment for administration. See Section 8.1, “The Tungsten Replicator Home Directory” and Section 8.2, “Establishing the Shell Environment”.
Prior to migrating applications to Tungsten Replicator test failover and recovery procedures from Chapter 8, Operations Guide. Be sure to try recovering a failed master and reprovisioning failed slaves.
Disable any automatic operating system patching processes. The use of automatic patching will cause issues when all database servers automatically restart without coordination. See Section 8.14.3, “Performing Maintenance on an Entire Dataservice”.
Regularly check for maintenance releases and upgrade your environment. Every version includes stability and usability fixes to ease the administrative process.
