Configure Metadata Caching (Optional)

Configure Metadata Caching (Optional)

Metadata caches manage items such as data objects, repository objects, and search tokens. The MDM Hub uses Infinispan for metadata caching. Infinispan is installed with the Hub Server. For the caches that the Hub Server uses, the Infinispan configuration file contains default attribute values.
Run the MDM Hub with the default attribute values for the caches. If you experience performance issues, you can fine-tune the attribute values to better suit your environment.
The following table summarizes the default attribute values:
Infinispan Element and Attribute
Default Value
Description
locking acquire-timeout
60000
Maximum time during which the Hub Server can try to acquire a lock.
transaction stop-timeout
30000
When a cache stops, this attribute sets the maximum time that Infinispan waits while the Hub Server finishes remote and local transactions.
transport cluster
infinispan-cluster
Name for the underlying group communication cluster.
transport stack
UDP
Type of configuration: UDP or TCP. The configurations are defined in the
jgroups-udp.xml
 file and the
jgroups-tcp.xml
 file.
transport node-name
$node$
Name of the current node. The Hub Server sets this attribute.
The node-name defaults to a combination of the host name and a random number. The number differentiates multiple nodes on the same host.
transport machine
$machine$
ID of the machine where the node runs. The Hub Server sets this attribute.
expiration lifespan
--
Maximum lifespan of a cache entry in milliseconds. When a cache entry exceeds its lifespan, the entry expires within the cluster. If you need to optimize performance, increase the lifespan for the following caches: DISABLE_WHEN_LOCK, DATA_OBJECTS, and REPOS_OBJECTS.
For example, you can increase the lifespan from one hour (3600000) to one day (86400000).
Each cache has its own default value for this attribute. To find the default values, open the
inifinspanConfig.xml
 file.
expiration interval
--
Maximum interval for checking the lifespan. If you need to optimize performance, increase the interval for the following caches: DISABLE_WHEN_LOCK, DATA_OBJECTS, and REPOS_OBJECTS.
For example, you can increase the interval from five seconds (5000) to five minutes (300000).
Each cache has its own default value for this attribute. To find the default values, open the
inifinspanConfig.xml
 file.
