SystemManagerBean

public SystemManagerBean()

Method Detail

scheduleConfigCacheReloader

public void scheduleConfigCacheReloader()

Description copied from interface: SystemManagerLocal

Schedules the internal timer job that periodically refreshes the configuration cache. This is needed in case a user changed the system configuration on another server in the HA cloud - this config cache reloader will load in that new configuration.

Specified by:

scheduleConfigCacheReloader in interface SystemManagerLocal

reloadConfigCache

public void reloadConfigCache(javax.ejb.Timer timer)

getDatabaseType

public DatabaseType getDatabaseType()

Description copied from interface: SystemManagerLocal

Returns the DatabaseType that corresponds to the database the JON Server uses for its backend.

This method is mainly to allow the caller to determine the kind of database in use so as to determine what syntax to use for a particular native query.

Specified by:

getDatabaseType in interface SystemManagerLocal

Returns:

the type of database

getSystemConfiguration

@Deprecated
public Properties getSystemConfiguration(org.rhq.core.domain.auth.Subject subject)

Deprecated.

Specified by:

getSystemConfiguration in interface SystemManagerLocal

Specified by:

getSystemConfiguration in interface SystemManagerRemote

getSystemSettings

public org.rhq.core.domain.common.composite.SystemSettings getSystemSettings(org.rhq.core.domain.auth.Subject subject)

Description copied from interface: SystemManagerRemote

Get the server cloud configuration. These are the server configurations that will be the same for all servers in the HA server cloud.

Specified by:

getSystemSettings in interface SystemManagerLocal

Specified by:

getSystemSettings in interface SystemManagerRemote

Parameters:

subject - user making the request

Returns:

the settings

setSystemSettings

public void setSystemSettings(org.rhq.core.domain.auth.Subject subject,
                              org.rhq.core.domain.common.composite.SystemSettings settings)

Description copied from interface: SystemManagerRemote

Set the server cloud configuration. The given properties will be the new settings for all servers in the HA server cloud.

Specified by:

setSystemSettings in interface SystemManagerLocal

Specified by:

setSystemSettings in interface SystemManagerRemote

Parameters:

subject - the user who wants to change the settings

settings - the new system configuration settings

loadSystemConfigurationCacheInNewTx

public void loadSystemConfigurationCacheInNewTx()

Description copied from interface: SystemManagerLocal

Grabs the current system configuration from the database and reloads the cache with it. This is meant for internal use only! You probably want to use #getSystemConfiguration() instead.

Specified by:

loadSystemConfigurationCacheInNewTx in interface SystemManagerLocal

loadSystemConfigurationCache

public void loadSystemConfigurationCache()

Description copied from interface: SystemManagerLocal

Grabs the current system configuration from the database and reloads the cache with it. This is meant for internal use only! You probably want to use #getSystemConfiguration() instead.

Specified by:

loadSystemConfigurationCache in interface SystemManagerLocal

Specified by:

validateSystemConfiguration in interface SystemManagerLocal

Throws:

InvalidSystemConfigurationException

enableHibernateStatistics

public void enableHibernateStatistics()

reconfigureSystem

public void reconfigureSystem(org.rhq.core.domain.auth.Subject whoami)
