If an IPv4 address is entered as an IPv4 compatible IPv6 address (deprecated) or an IPv4 mapped IPv6 address (for example ::FFFF:1.2.3.4) it is converted to a standard IPv4 dotted decimal address. IPv6 addresses should not be used for CICS Transaction Server for z/OS, Version 3 Release 2 and earlier releases. This is used for IPIC SYSLINK connections. |

Primary CMAS name | PRICMAS | The name of the CMAS that is assigned the task of monitoring the availability of this CICS system. When the CICS system is part of a CICSplex that is managed by a single CMAS, specify the name of that CMAS. When multiple CMASs participate in managing the CICSplex, identify the CMAS to which the CICS system normally connects. Naming a CMAS does not prevent the CICS system from connecting to another CMAS when, for example, the primary CMAS is not available. |

RS server read interval | READRS |
Within a workload running in optimized mode, this value specifies the minimum interval between target region status refreshes that a
routing region would request from the CICS CFDT server. This value will be used to override the default interval value
specified in CICSplex definition, which is the parent of this CICS system definition. The value range is from 0 to 2000 or INHERIT, and represents units of milliseconds:
A low value mean that the router will refresh a target's status from the RS server more often than for a higher value. For workloads in QUEUE mode, this will result in a task load more evenly balanced across the CICS regions in the workload target scope (assuming all other health and link factors are equal) . However, the utilization of the RS server will be correspondingly increased, which may consequently result in a higher utilization of your coupling facility. A value of 1000 represents a one second interval. The default value is 200 milliseconds The value specified here will be applied the next time this CICS region is started. If you want the change to be applied to a running instance of this CICS region, then it may be changed in-flight using the MAS views. |
Time data is kept after monitoring stops (minutes) | RETENTION |

|
Time zone offset | TMEZONEO |
The adjustment value that is to be applied to the computed time. This value is used to resolve time references
in areas that do not use a standard zone. Specify:
|
RS server top tier | TOPRSUPD |
For sysplex optimized workloads, this value is converted from a task load percentage to an actual task count. That count
will be subtracted from the MAXTASK value for the region to determine top tier task load range. This value will
be used to override the default value specified in CICSplex definition, which is the parent of this CICS system definition.
The value range is from 1 to 25, or INHERIT.
The default value is 5%. You should only change this value after giving consideration to the impact that the change may have on your workload and coupling facility throughput. Any change to this value will be applied at the next region startup. |
Sample interval for transaction monitoring | TRANSAMP | The number of seconds in the range 0 - 86400 that CICSPlex SM is to wait between requests to collect sample data for the named type of monitoring. A value of INHERIT means that the CICS system uses the value specified with its associated monitor specification. |
RS server update frequency | UPDATERS |
Within a workload running in optimized mode, this value specifies the frequency with which the CICS CFDT (RS) server will
be called to modify the value of the task load within a target CICS region. This value will be used
to override the default frequency value specified in CICSplex definition, which is the parent of this CICS system definition. The value range is from 0 to 25, or INHERIT:
For example, with a MAXTASKS setting of 120, and with this attribute set to 20, the RS Server will be called to update the WLM load count when the regions task count changes between:
The RS Server would be updated when a regions task load increments or decrements across these boundaries. If you specify a value that is at the lower end of the 1-25 scale, then that will cause an increase in the frequency of updates to the RS Server across its task load range. For workloads in QUEUE mode, this will result in a task load more evenly balanced across the CICS regions in the workload target scope (assuming all other health and link factors are equal) . However, the utilization of the RS server will be correspondingly increased, which may consequently result in a higher utilization of your coupling facility. The value specified here will be applied the next time this CICS region is started. If you want the change to be applied to a running instance of this CICS region, then it may be changed in-flight using the MAS views. |
WLM optimization enablement | WLMOPTEN |
This attribute controls the enablement of the optimized dynamic routing function. When set to ENABLED, the region will attempt to connect to the CICS Region Status server when the CICSplex SM workload management agent starts. If that connection is successful, then the region will be eligible to participate in optimized workload routing requests. If this attribute is set to DISABLED, then the region will not connect to the Region Status server when it starts, and optimized dynamic workload routing requests will be suppressed. The setting of this definition may be overridden at run time through the MAS views. |
Task load queue mode | WLMQMODE |
This attribute is used by CICSPlex SM Workload Manager. This value specifies how the queued task load of a target
CICS region is to be evaluated:
The default value is ALL. Any change to this value will be applied at the next region startup. |
Routing region active at startup | WLMSTATUS |
Indicates whether or not this CICS system is to participate in its associated workload as a routing region when the
CICS system is started. Options are:
Use the WLM specifications to CICS systems link (EYUSTARTLNKSWSCS) view, the WLM specifications to CICS system group links (EYUSTARTLNKSWSCG) view, or Workload management Map function to identify the associated workload. If the CICS system is not associated with a workload, it will not be activated as a routing region. A routing region would normally have this option set to YES. A target region must also have this option set to YES, if it is to receive requests using the CICS distributed routing model (DSRTPGM). |
Task load health threshold | WLMTHRSH |
This attribute is used by CICSPlex SM Workload Manager. It specifies a percentage threshold of the current region's task load,
which is calculated by dividing the current task count by the maximum task count. When the load for a target
region reaches this threshold, then WLM considers the region to be relatively unhealthy. This will cause higher link weights to
be applied to the WLM routing algorithm when evaluating this region. When a target scope covers local and remote regions
relative to the router, then WLM will favour local targets over remote ones. The effect of this attribute is that
when this load threshold in the local regions is achieved, then WLM will start to favour remote targets instead. When
all targets in the scope achieve this load threshold, then WLM will revert to favouring local targets again. The value range is from 1 to 100, and the default value is 60. The value specified here will be applied the next time this CICS region is started. Note: this value is nullified when applied to the routing factor of link neutral dynamic routing requests. This is because the link weight itself is ignored for the LNQUEUE and LNGOAL algorithms. |
