Clustered Deployment Recommendations
If you are deploying TIBCO MDM in a cluster (more than one application server), you can deploy with one of these options.
| Options | Description |
|---|---|
| Option 1 (recommended) | MQ_HOME is on a common file system which is shared between all application servers. The ConfigValues.xml file has configuration for all instances. The advantage is that servers are guaranteed to run same version. Any mismatch of version will result of failures. In both options, MQ_LOG is not shared, each application server should have its separate log directory. It is recommended that MQ_LOG points to internal disks to reduce the disk write overhead. MQ_COMMOM_DIR is on a common file system which is shared between all application servers. |
| Option 2 | Each application server has a separate
MQ_HOME where all application images are stored. The
config/
directory must be identical for all application servers, including
ConfigValues.xml. The
ConfigValues.xmlis to be managed using the Configurator.
This option should be used only if MQ_HOME sharing is not possible. Care should be taken to ensure that the config/ directory is synchronized between all instances whenever a configuration change is made. MQ_COMMOM_DIR is on a common file system which is shared between all application servers. |
