GRS Attributes

The GRS (global resource serialization) attribute group monitors ring status and ring message delays.


Actual Response Time Actual measured ring response time in milliseconds. Valid value is an integer in the range of 0 through 2147483647, and can include the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 32.

Current RSA Message Size Current size, in bytes, of the outgoing RSA message. Valid value is an integer in the range of 0 through 2147483647, and can include the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 144.

Expected Response Time Anticipated (or average) time, in milliseconds, that a requester must wait for access to a global resource. Valid value is an integer in the range of 0 through 2147483647, and can include the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 78.

GRS Mode The serialization propagation topology. Valid values are: Ring, Star, or None.

Managed System A sysplex in your enterprise that is being monitored by OMEGAMON XE for z/OS agents. Valid value is a character string with a maximum length of 32 bytes, in the format <plexname>:MVS:SYSPLEX.

Maximum RSA Message Size Maximum size of the RSA message in bytes. Valid value is an integer in the range of 0 through 2147483647, and can include the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 32768.

Resident Milliseconds Minimum amount of time, in milliseconds, the RSA message is delayed in each z/OS image in the GRS complex. Valid value is an integer in the range of 0 through 2147483647, and can include the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 3.

Ring Acceleration Number of consecutive z/OS images in the GRS complex that must process the RSA message before GRS grants access to a global resource. Valid value is an integer in the range of 0 through 65535, and can include the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 2.

Status Status of each system in the global resource serialization complex. Valid values are:

System Name Name of the z/OS image connected to the facility. Valid format is a simple text string from 1 through 8 characters; for example, SYSA.

Tolerance Interval Maximum amount of time, in milliseconds, GRS waits before it detects an overdue RSA message. Valid value is an integer in the range of 0 through 2147483647, and can include the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 75000.
