Finding information for logrec log stream

Use Table 1 to find information to help you set up and use the logrec log stream.

Table 1. Finding Logrec Log Stream information
What is your goal?	You need to read:
Learn about logrec error records. Decide whether to use the logrec data set or logrec log stream as your logrec recording medium. Plan to use the logrec log stream.	z/OS MVS Diagnosis: Tools and Service Aids
Learn requirements for system logger applications.	Understand the requirements for system logger.
Develop a naming convention for system logger resources.	Develop a naming convention for system logger resources
Do set-up for the logrec log stream.	See Preparing to use system logger applications.
Size the coupling facility structure space needed for the logrec log stream.	See the appendix on coupling facility structures in System/390® MVS™ Parallel Sysplex® Configuration Cookbook, SG24-4706.
Activate the LOGR subsystem.	Activate the LOGR subsystem.
Use the LOGR subsystem to obtain logrec log stream error records.	z/OS MVS Programming: Assembler Services Guide See z/OS MVS Diagnosis: Tools and Service Aids for logrec specific information.
Delete logrec log data.	Managing log data: How much? For how long? Deleting log data and log data sets
Tune the logrec log stream definition using SMF record type 88.	z/OS MVS System Management Facilities (SMF)
Determine your current and alternate logrec medium names: To find your current logrec medium, issue the DISPLAY LOGREC command. To find the current and alternate logrec mediums, use the IEANTRT service.	For the DISPLAY LOGREC command, see z/OS MVS System Commands. For the IEANTRT service in an authorized environment, see z/OS MVS Programming: Authorized Assembler Services Reference EDT-IXG. For the IEANTRT service in an unauthorized environment, see z/OS MVS Programming: Assembler Services Reference IAR-XCT.
Issue the SETLOGRC command to change your logrec medium.	z/OS MVS System Commands
At IBM's request, gather system logger component trace data.	z/OS MVS Diagnosis: Tools and Service Aids
