JBoss EAP 6.2 Model Reference

Children (2)

property A cache store property with name and value.
write-behind Configures a cache store as write-behind instead of write-through.

WRITE_BEHIND Configures a cache store as write-behind instead of write-through.

Attributes (8)

datasource A datasource reference for this datastore.

Attribute	Value
Type	STRING
Nillable	false
Expressions Allowed	true
Storage	configuration
Access Type	read-write
Restart Required	all-services

fetch-state If true, fetch persistent state when joining a cluster. If multiple cache stores are chained, only one of them can have this property enabled.

Attribute	Value
Default Value	true
Type	BOOLEAN
Nillable	true
Expressions Allowed	true
Storage	configuration
Access Type	read-write
Restart Required	all-services

passivation If true, data is only written to the cache store when it is evicted from memory, a phenomenon known as 'passivation'. Next time the data is requested, it will be 'activated' which means that data will be brought back to memory and removed from the persistent store. f false, the cache store contains a copy of the contents in memory, so writes to cache result in cache store writes. This essentially gives you a 'write-through' configuration.

Attribute	Value
Default Value	true
Type	BOOLEAN
Nillable	true
Expressions Allowed	true
Storage	configuration
Access Type	read-write
Restart Required	all-services

preload If true, when the cache starts, data stored in the cache store will be pre-loaded into memory. This is particularly useful when data in the cache store will be needed immediately after startup and you want to avoid cache operations being delayed as a result of loading this data lazily. Can be used to provide a 'warm-cache' on startup, however there is a performance penalty as startup time is affected by this process.

Attribute	Value
Default Value	false
Type	BOOLEAN
Nillable	true
Expressions Allowed	true
Storage	configuration
Access Type	read-write
Restart Required	all-services

purge If true, purges this cache store when it starts up.

Attribute	Value
Default Value	true
Type	BOOLEAN
Nillable	true
Expressions Allowed	true
Storage	configuration
Access Type	read-write
Restart Required	all-services

shared This setting should be set to true when multiple cache instances share the same cache store (e.g., multiple nodes in a cluster using a JDBC-based CacheStore pointing to the same, shared database.) Setting this to true avoids multiple cache instances writing the same modification multiple times. If enabled, only the node where the modification originated will write to the cache store. If disabled, each individual cache reacts to a potential remote update by storing the data to the cache store.

Attribute	Value
Default Value	false
Type	BOOLEAN
Nillable	true
Expressions Allowed	true
Storage	configuration
Access Type	read-write
Restart Required	all-services

singleton If true, the singleton store cache store is enabled. SingletonStore is a delegating cache store used for situations when only one instance in a cluster should interact with the underlying store.

Attribute	Value
Default Value	false
Type	BOOLEAN
Nillable	true
Expressions Allowed	true
Storage	configuration
Access Type	read-write
Restart Required	all-services

string-keyed-table The database table used to store cache entries.

Attribute	Value
Type	OBJECT
Nillable	true
Expressions Allowed	false
Storage	configuration
Access Type	read-write
Restart Required	no-services

Operations (2)

add Adds a JDBC cache store configuration element to the cache.

Request Parameter	Type	Required	Expressions Allowed	Default value	Description
shared	BOOLEAN	false	true	false	This setting should be set to true when multiple cache instances share the same cache store (e.g., multiple nodes in a cluster using a JDBC-based CacheStore pointing to the same, shared database.) Setting this to true avoids multiple cache instances writing the same modification multiple times. If enabled, only the node where the modification originated will write to the cache store. If disabled, each individual cache reacts to a potential remote update by storing the data to the cache store.

singleton	BOOLEAN	false	true	false	If true, the singleton store cache store is enabled. SingletonStore is a delegating cache store used for situations when only one instance in a cluster should interact with the underlying store.
properties	LIST	false	false		A list of cache store properties.
datasource	STRING	true	true		A datasource reference for this datastore.
string-keyed-table	OBJECT	false	false		The database table used to store cache entries.

remove Removes a JDBC cache store configuration element from the cache.
