Before you can read information from the log stream, you start a browse session using the REQUEST=START request of IXGBRWSE. A browse session lasts from the time that an application issues IXGBRWSE REQUEST=START until it issues IXGBRWSE REQUEST=END. A log stream can have multiple browse sessions occurring at the same time.
The REQUEST=START request returns a browse token, which is a unique 4-byte identifier for a particular browse session. Subsequent IXGBRWSE requests in a browse session use the browse token to identify the session to system logger. Once an application issues the REQUEST=END request, the browse session ends and system logger will no longer accept IXGBRWSE requests with the browse token for that session.
The browse cursor indicates where in the log stream IXGBRWSE will resume browsing on the next request. Each browse session has a browse cursor.
