Summary of system logger services
System logger provides the following set of services:
- IXGINVNT
- Define and maintain log stream and coupling facility structure
information in the LOGR policy dynamically.
See 'IXGINVNT: Managing the LOGR Policy' in z/OS MVS Programming: Assembler Services Guide.
You can also use the IXCMIAPU utility to specify log stream and structure definitions in the LOGR policy. IXCMIAPU also enables you to request a report of current log stream definitions.
- IXGCONN
- Connect and disconnect an application to and from a log stream. See the topic on IXGCONN: Connecting to and disconnecting from a log stream.
- IXGWRITE
- Write user-defined log data to a log stream. See 'IXGWRITE: Writing to a Log Stream' in z/OS MVS Programming: Assembler Services Guide.
- IXGBRWSE
- Browse (read) data from a log stream. See 'IXGBRWSE Requests' in z/OS MVS Programming: Assembler Services Guide.
- IXGDELET
- Delete data from a log stream. See the topic on IXGDELET: Deleting log blocks from a log stream.
- IXGIMPRT
- Import (write) log blocks to a log stream with a log block identifier and timestamp. See 'IXGIMPRT: Import Log Blocks' in z/OS MVS Programming: Assembler Services Guide.
- IXGQUERY
- Retrieve information from a log stream. See 'IXGQUERY: Get Information About a Log Stream' in z/OS MVS Programming: Assembler Services Guide.
- IXGOFFLD
- Initiate an offload of log data from the coupling facility structure for coupling facility log streams and from local storage buffers for DASD-only log streams to DASD log data sets. See 'IXGOFFLD: Initiate Offload to DASD Log Data Sets' in z/OS MVS Programming: Assembler Services Guide.
- IXGUPDAT
- Modify the UTC time stamp maintained in the control information for a log stream. See 'IXGUPDAT: Modify Log Stream Control Information' in z/OS MVS Programming: Assembler Services Guide.
The following services contain parameters for both authorized and
unauthorized programs:
- IXGCONN
- IXGBRWSE
- IXGWRITE
- IXGDELET
