About this task
If more than one container server exists, the default
cache policy ensures that all data is replicated at least one time,
so that each container server can host primary and replica shards
of the cache data. By default, data is read only from the primary
shard but you can configure the embedded global cache to support read
access to replica shards.
You define that your embedded global
cache can read data from replica shards of a cache map by configuring
the
deployment.xml file. You then configure the
embedded global cache by using one of the following methods:
- Place the deployment.xml file in a directory
of the IBM® Integration Bus work path.
- Use the mqsichangeproperty command to set a
property on the integration node cache manager to point to the deployment.xml file.
- Use the mqsichangeproperty command to set a
property on the integration server cache manager to point to the deployment.xml file.
The embedded global cache can use only one
deployment.xml file.
Any property settings, if set, are used in the following order of
precedence:
Note: If you choose to configure the property on more than one
integration server (or integration node) in the same IBM Integration Bus installation, the properties
must result in the same map configuration to ensure consistency.
