Method Detail

start0

public void start0()
            throws GridException

Overrides:

start0 in class GridCacheManagerAdapter<K,V>

Throws:

GridException - If failed.

onKernalStart0

protected void onKernalStart0()
                       throws GridException

Overrides:

onKernalStart0 in class GridCacheManagerAdapter<K,V>

Throws:

GridException - If failed.

onKernalStop0

public void onKernalStop0(boolean cancel)

Overrides:

onKernalStop0 in class GridCacheManagerAdapter<K,V>

Parameters:

cancel - Cancel flag.

dgc

public void dgc()

Runs DGC procedure on demand using GridCacheConfiguration.getDgcSuspectLockTimeout() to identify suspect locks.

Method blocks current thread until locks are examined and all DGC requests are sent to remote nodes.

DGC does not remove locks if GridCacheConfiguration.isDgcRemoveLocks() is set to false.

dgc

public void dgc(long suspectLockTimeout,
       boolean global,
       boolean rmvLocks)

Runs DGC procedure on demand using provided parameter to identify suspect locks.

Method blocks current thread until locks are examined and all DGC requests are sent to remote nodes and (if global is true) all nodes having this cache get signal to start DGC procedure.

Parameters:

suspectLockTimeout - Custom suspect lock timeout (should be greater than or equal to 0).

global - If true then DGC procedure will start on all nodes having this cache.

rmvLocks - If false then DGC does not remove locks, just report them to log.

toString

public String toString()

Overrides:

toString in class GridCacheManagerAdapter<K,V>
