Read this section if the resource type your task is waiting on starts with the characters LG, indicating log manager. The journal name, given as the resource name, refers to the last element of the MVS™ log stream name. For example, in the log stream name PAYRO.ACC0001.UJ4321, the journal name, for these purposes, is UJ4321.
If you do encounter any of these waits, look at the MVS console for messages prefixed with ‘IXG’. These are the MVS system logger messages and may provide further information about the cause of the wait. The MVS system console may also reveal evidence of resource contention within MVS, a possible cause of a log manager wait.
If the task is writing to a journal on an SMF log, the journal name is the name of the journal.
The task is the first task to request that the currently active log buffer be flushed. The task waits for 30 milliseconds to allow other tasks to append more records to the buffer.
The task is waiting for the flush of a log buffer to complete. It is resumed by the task that performs the flush operation.
The task may be purged if the log stream is not DFHLOG, the primary system log.
During an INITIAL start of CICS®, CICS calls the MVS system logger macro IXGDELET ALL. CICS waits until the MVS system logger posts the ECB.
During keypoint processing, CICS calls the MVS system logger macro IXGDELET RANGE. CICS waits until the MVS system logger posts the ECB.
During an emergency restart of CICS, or transaction backout, CICS calls the MVS system logger macro IXGBRWSE END. CICS waits until the MVS system logger posts the ECB.
During an emergency restart of CICS, CICS calls the MVS system logger macro IXGBRWSE END. CICS waits until the MVS system logger posts the ECB.
During an emergency restart of CICS, or transaction backout, CICS calls the MVS system logger macro IXGBRWSE READBLOCK. CICS waits until the MVS system logger posts the ECB.
During an emergency restart of CICS, CICS calls the MVS system logger macro IXGBRWSE READCURSOR. CICS waits until the MVS system logger posts the ECB.
During an emergency restart of CICS, or transaction backout, CICS calls the MVS system logger macro IXGBRWSE START. CICS waits until the MVS system logger posts the ECB.
During an emergency restart of CICS, CICS calls the MVS system logger macro IXGBRWSE START. CICS waits until the MVS system logger posts the ECB.
In several situations, CICS calls the MVS system logger macro IXGWRITE. CICS waits until the MVS system logger posts the ECB.
