Method Detail

getSteadyPoolSize

@Min(value=0L)
String getSteadyPoolSize()

Gets the value of the steadyPoolSize property. (slsb,eb) number of bean instances normally maintained in pool. When a pool is first created, it will be populated with size equal to steady-pool-size. When an instance is removed from the pool, it is replenished asynchronously, so that the pool size is at or above the steady-pool-size. This addition will be in multiples of pool-resize-quantity. When a bean is disassociated from a method invocation, it is put back in the pool, subject to max-pool-size limit. If the max pool size is exceeded the bean id destroyed immediately. A pool cleaning thread, executes at an interval defined by pool-idle-timeout-in-seconds. This thread reduces the pool size to steady-pool-size, in steps defined by pool-resize-quantity. If the pool is empty, the required object will be created and returned immediately. This prevents threads from blocking till the pool is replenished by the background thread. steady-pool-size must be greater than 1 and at most equal to the max-pool-size.

Returns:

possible object is String

setSteadyPoolSize

void setSteadyPoolSize(String value)
                       throws PropertyVetoException

Sets the value of the steadyPoolSize property

Parameters:

value - allowed object is String

Throws:

PropertyVetoException

getPoolResizeQuantity

@Min(value=0L)
String getPoolResizeQuantity()

Gets the value of the poolResizeQuantity property. (slsb,eb) size of bean pool grows (shrinks) in steps specified by pool-resize-quantity, subject to max-pool-size (steady-pool-size) limit.

Returns:

possible object is String

setPoolResizeQuantity

void setPoolResizeQuantity(String value)
                           throws PropertyVetoException

Sets the value of the poolResizeQuantity property.

Parameters:

value - allowed object is String

Throws:

PropertyVetoException

getMaxPoolSize

@Min(value=0L)
String getMaxPoolSize()

Gets the value of the maxPoolSize property. (slsb,eb) maximum size, a pool can grow to. A value of 0 implies an unbounded pool. Unbounded pools eventually shrink to the steady-pool-size, in steps defined by pool-resize-quantity.

Returns:

possible object is String

setMaxPoolSize

void setMaxPoolSize(String value)
                    throws PropertyVetoException

Sets the value of the maxPoolSize property.

Parameters:

value - allowed object is String

Throws:

PropertyVetoException

getCacheResizeQuantity

@Min(value=1L)
String getCacheResizeQuantity()

Gets the value of the cacheResizeQuantity property. (eb,sfsb) Cache elements have identity, hence growth is in unit steps and created on demand. Shrinking of cache happens when cache-idle-timeout-in-seconds timer expires and a cleaner thread passivates beans which have been idle for longer than cache-idle-timeout-in-seconds. All idle instances are passivated at once. cache-resize-quantity does not apply in this case. When max cache size is reached, an asynchronous task is created to bring the size back under the max-cache-size limit. This task removes cache-resize-quantity elements, consulting the victim-selection-policy. Must be greater than 1 and less than max-cache-size.

Returns:

possible object is String

setCacheResizeQuantity

void setCacheResizeQuantity(String value)
                            throws PropertyVetoException

Sets the value of the cacheResizeQuantity property.

Parameters:

value - allowed object is String

Throws:

PropertyVetoException

getMaxCacheSize

@Min(value=0L)
String getMaxCacheSize()

Gets the value of the maxCacheSize property. (sfsb,eb) specifies the maximum number of instances that can be cached. For entity beans, internally two caches are maintained for higher concurrency: (i) Ready (R$) (ii) Active in an Incomplete Transaction(TX$) The TX$ is populated with instances from R$ or from the Pool directly. When an instance in TX$ completes the transaction, it is placed back in R$ (or in pool, in case an instance with same identity already is in R$). max-cache-size only specifies the upper limit for R$. The container computes an appropriate size for TX$. For SFSBs, after the max-cache-size is reached, beans(as determined by victim-selection-policy) get passivated.

Returns:

possible object is String

setMaxCacheSize

void setMaxCacheSize(String value)
                     throws PropertyVetoException

Sets the value of the maxCacheSize property.

Parameters:

value - allowed object is String

Throws:

PropertyVetoException

getPoolIdleTimeoutInSeconds

@Min(value=0L)
String getPoolIdleTimeoutInSeconds()

Gets the value of the poolIdleTimeoutInSeconds property. (slsb,eb) defines the rate at which the pool cleaning thread is executed. This thread checks if current size is greater than steady pool size, it removes pool-resize-quantity elements. If the current size is less than steady-pool-size it is increased by pool-resize-quantity, with a ceiling of min (current-pool-size + pool-resize-quantity, max-pool-size) Only objects that have not been accessed for more than pool-idle-timeout-in-seconds are candidates for removal.

Returns:

possible object is String

setPoolIdleTimeoutInSeconds

void setPoolIdleTimeoutInSeconds(String value)
                                 throws PropertyVetoException

Sets the value of the poolIdleTimeoutInSeconds property.

Parameters:

value - allowed object is String

Throws:

PropertyVetoException

getCacheIdleTimeoutInSeconds

@Min(value=0L)
String getCacheIdleTimeoutInSeconds()

Gets the value of the cacheIdleTimeoutInSeconds property. (eb, sfsb) specifies the rate at which the cache cleaner thread is scheduled. All idle instances are passivated at once.

Returns:

possible object is String

setCacheIdleTimeoutInSeconds

void setCacheIdleTimeoutInSeconds(String value)
                                  throws PropertyVetoException

Sets the value of the cacheIdleTimeoutInSeconds property.

Parameters:

value - allowed object is String

Throws:

PropertyVetoException

getRemovalTimeoutInSeconds

@Min(value=0L)
String getRemovalTimeoutInSeconds()

Gets the value of the removalTimeoutInSeconds property. (sfsb) Instance is removed from cache or passivation store, if it is not accesed within this time. All instances that can be removed, will be removed.

Returns:

possible object is String

setRemovalTimeoutInSeconds

void setRemovalTimeoutInSeconds(String value)
                                throws PropertyVetoException

Sets the value of the removalTimeoutInSeconds property.

Parameters:

value - allowed object is String

Throws:

PropertyVetoException

getVictimSelectionPolicy

@Pattern(regexp="(nru|fifo|lru)")
String getVictimSelectionPolicy()

Gets the value of the victimSelectionPolicy property. (sfsb) Victim selection policy when cache needs to shrink. Victims are passivated. Entity Bean Victims are selected always using fifo discipline Does not apply to slsb because it does not matter, which particular instances are removed. fifo method picks victims, oldest instance first. lru algorithm picks least recently accessed instances. nru policy tries to pick 'not recently used' instances and is a pseudo-random selection process.

Returns:

possible object is String

setVictimSelectionPolicy
