Parameters

The parameters for SETLOGR MANAGE are:

MANAGE

Identifies the system logger resource management policy on a system.

OFFLOAD

Identifies the system logger policy on the system that manages log stream offload activity. See "Offloading log data from interim storage by freeing and/or moving it to DASD" in z/OS MVS Setting Up a Sysplex for more information about logger offload processing.

ALLOCAHEAD(YES|NO)

Specifies whether the system will proactively manage advanced-current offload data sets for log streams that are defined with an LS_ALLOCAHEAD value that is greater than zero (0). See "Offloading log data from interim storage by freeing and/or moving it to DASD" in z/OS MVS Setting Up a Sysplex for more information about the logger behavior that is based on the ALLOCAHEAD and LS_ALLOCAHEAD parameters.

The following options are possible:

YES

Indicates that the system will proactively manage advanced-current log stream offload data sets for log streams that are defined with an LS_ALLOCAHEAD value that is greater than zero (0) and are connected on the system in order to keep the log stream more readily available.

NO

Indicates that the system will not proactively manage advanced-current log stream offload data sets for log streams that are connected on the system. Access to any new or existing offload data sets to be used to move log data from the primary/interim storage to DASD is managed on the system only as needed on an on-demand basis. This means that the system will only allocate and open the actual current offload data set when it is explicitly needed for an offload activity to move log data to DASD on this system.

You can use the Display LOGGER,IXGCNF[,MANAGE] command to view the system logger configuration parameter settings.

LOGRCDS

Specifies the system logger policy on the system that manages access to the LOGR couple data set (CDS). See "Prevent a z/OS® image from accessing LOGR couple data sets" in z/OS MVS Setting Up a Sysplex for more information about LOGR CDS management.

ALLOWACCESS(YES)

Specifies whether the particular system will make use of LOGR couple data sets when they are presented to system logger by the Cross-system Coupling Facility (XCF) component. System logger requires the use of at least the primary LOGR couple data set to perform its operations. However,some z/OS images within the sysplex should not have any access to these couple data sets.

The following options are possible:

Note: The NO option is not supported on the SETLOGR command for the ALLOWACCESS keyword.

YES

Indicates that system logger should make use of the LOGR couple data sets when they are presented by XCF on the z/OS image.

If the z/OS image was restarted with the MANAGE LOGRCDS ALLOWACCESS(NO) specification, then specifying ALLOWACCESS(YES) on the SETLOGR command allows system logger to make use of LOGR couple data sets when they are made available to the sysplex, for example with subsequent SETXCF COUPLE,TYPE=LOGR,PCOUPLE... commands. When other systems in the sysplex were already using LOGR CDSs, then IBM® recommends specifying on the PCOUPLE keyword the current primary LOGR CDS. The target system of the command will use the current primary and alternate LOGR CDSs.

If the original system restart option was specified as NO and then changed through a command to YES, and if the IXGLOGR address space is later restarted, then the YES specification remains in effect.

See "Prevent a z/OS image from accessing LOGR couple data sets" in z/OS MVS Setting Up a Sysplex for more information about using this option.

You can use the DISPLAY LOGGER,IXGCNF[,MANAGE] command to view the system logger configuration parameter settings.
