Method Detail

getHostingServer

ServerMBean getHostingServer()

Returns the name of the server that currently hosts the singleton service.

Returns:

The hostingServer value

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

getUserPreferredServer

ServerMBean getUserPreferredServer()

Returns the server that the user prefers the singleton service to be active on.

Returns:

The UserPreferredServer value

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

setUserPreferredServer

void setUserPreferredServer(ServerMBean t)

Parameters:

t - The new UserPreferredServer value

getAdditionalMigrationAttempts

int getAdditionalMigrationAttempts()

A migratable service could fail to come up on every possible configured server. This attribute controls how many further attempts, after the service has failed on every server at least once, should be tried. Note that each attempt specified here indicates another full circuit of migrations amongst all the configured servers. So for a 3-server cluster, and a value of 2, a total of 4 additional migrations will be attempted. (the original server is never a valid destination)

Default Value:

2

setAdditionalMigrationAttempts

void setAdditionalMigrationAttempts(int attempts)

Parameters:

attempts - number of additional attempts

See Also:

getAdditionalMigrationAttempts()

getMillisToSleepBetweenAttempts

int getMillisToSleepBetweenAttempts()

Controls how long of a pause there should be between the migration attempts described in getAdditionalMigrationAttempts(). Note that this delay only happens when the service has failed to come up on every server. It does not cause any sort of delay between attempts to migrate otherwise.

Default Value:

300000

setMillisToSleepBetweenAttempts

void setMillisToSleepBetweenAttempts(int millis)

Parameters:

millis - how long to pause, in millis
