Example 1 with AcsBinLogFormatter

use of alma.acs.logging.formatters.AcsBinLogFormatter in project ACS by ACS-Community.

the class ClientLogManager method internalInitRemoteLogging.

/**
     * {@link #initRemoteLogging(ORB, Manager, int, boolean)} and {@link #initRemoteLoggingForService(ORB, boolean)}
     * delegate to this method for the initialization of the remote logging.
     * <P>
     * If the passed manager is <code>null</code>, <code>internalInitRemoteLogging</code> gets
     * the log service reference from the naming service; if the manager is not <code>null</code>,
     * it asked the manager for the reference to the log service.
     * 
     * @param orb The not <code>null</code> ORB
     * @param manager the ACS manager (it can be <code>null</code>)
     * @param managerHandle the handle assigned by the ACS Manager for this client;
     *                      ignored if the manager is <code>null</code>
     * @param retry if <code>true</code>, a failing connection to the log service will trigger up to 5 other attempts, every 10 seconds.
     * @return <code>true</code> if remote logging was initialized successfully
