isFinalFlush

public static boolean isFinalFlush(oracle.mds.core.MDSSession mdsSess)

Deprecated. relaced by isFinalFlushCurrentMDSSess()

Parameters:

mdsSess - it is ignored. Always works in the context of current mds sesssion.

Returns:

true or false depending on whether this is the final flush call

getSingleFlushFlag

@Deprecated
public boolean getSingleFlushFlag()

Deprecated.

Returns the fingleFlush flag value on the MDSTransManager instance.

Returns:

singleflush flag value from MDSTransManager instance

See Also:

setSingleFlushGlobal(boolean)

getSingleFlushFlagGlobal

@Deprecated
public static boolean getSingleFlushFlagGlobal()

Deprecated.

Returns the global i.e. jvm wide fingleFlush flag value.

Returns:

global singleflush flag value

See Also:

setSingleFlushGlobal(boolean)

setSingleFlushFlag

@Deprecated
public void setSingleFlushFlag(boolean flag)

Deprecated.

This method is a No-OP. Keeping the API for backward compatibility. Sets the fingleFlush flag on the MDSTransManager instance. This can be used to enable or disable singleflush functionality for the given request. This flags works in conjunction with the jvm wide singleflush flag which can be set using setSingleFlushGlobal(boolean) method. SingleFlush will be enabled if either or the two flags are set to true, disabled otherwise. Note that this API will have no effect when singleflush is enabled by default.

Parameters:

flag - singleflush flag value

See Also:

setSingleFlushGlobal(boolean)

setSingleFlushFlagGlobal

@Deprecated
public static void setSingleFlushFlagGlobal(boolean flag)

Deprecated.

This method is a No-OP. Keeping the API for backward compatibility. Sets the global flag i.e. jvm wide singleFlush flag. This can be used to enable or disable singleflush jvm wide functionality.

SingleFlush will be enabled if either or the two flags are set to true, disabled otherwise. Note that this API will have no effect when singleflush is enabled by default.

Parameters:

flag - singleflush flag value
