CICSplex Storage Analysis attribute group

The CICSplex Storage Analysis attributes report on usage of the Dynamic Storage Area (DSA) for a CICS region. Use the CICSplex Storage Analysis attributes in situations to determine if there are any storage-related problems, such as a short-on-storage (SOS) condition.

These attributes provide data for the Storage Analysis table view.

Area Indicates the name of the Dynamic Storage Area (DSA) or Extended Dynamic Storage Area (EDSA). Value format is an integer.

CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS operating system has a unique name. This name is an alphanumeric string, with a maximum of eight characters, and case-sensitive. CICS region names are always in uppercase characters.

Origin Node The combination of z/OS System ID (SMFID) and CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case-sensitive.

When a situation is true, the system compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.

Percent Used Indicates the percentage of storage in use for the specified dynamic storage area. The value format is a percentage in the range 0-100.

SOS Indicates whether a short-on-storage (SOS) condition exists for a given dynamic storage area. These are the values: Yes and No.

Storage Allocated Indicates the amount of storage (in kilobytes) allocated for the specified dynamic storage area. The value format is a positive integer, maximum four bytes.

Storage Available Indicates the amount of storage (in kilobytes) currently available within the specified dynamic storage area. This value represents storage within one or more extents that has not been allocated to a subpool. It is calculated by subtracting the storage in use from the amount of storage allocated. The value format is a positive integer of maximum four bytes.

Storage Limit Indicates the total amount of storage (in kilobytes) that you are allowed to request from CICS for the specified dynamic storage area. The value format is a positive integer, maximum four bytes.

Storage in Use Indicates the amount of storage (in kilobytes) that has been CICS GETMAINed from the dynamic storage area. The value format is a positive integer, maximum four bytes.

System ID Indicates the four character name that uniquely identifies an active z/OS operating system within a given CICSplex. The value format is an alphanumeric string, maximum four characters, and case-sensitive. z/OS System IDs are always in uppercase characters.
