IBM Tivoli OMEGAMON XE for CICS on z/OS, Version 5.1.0

CICSplex LSR Pool Details attribute group

The CICSplex LSR Pool Details attribute group provides information about a specific Local Shared Resource (LSR) pool that has been built in CICS for VSAM files and their impact on performance.

Note:
The attributes within the CICSplex LSR Pool Details group are stored for historical retrieval within the Tivoli Data Warehouse. Selected attributes within this group are candidates for the Tivoli Data Warehouse summarization and pruning features.

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.

Buffer Number The number of buffers used by the local shared resource pool. The value format is an integer of maximum four bytes.

Buffer Reads The number of buffer reads, which is number of times a control interval has to be read from disk. The value format is an integer of maximum four bytes.

Buffer Size The local shared resource pool buffer size. The value format is an integer of maximum two bytes.

Buffer Type The type of hiperspace buffer, whether index or data, that is in use.

Buffer Writes The number of buffer WRITEs for the logical shared resource pool. The value format is an integer of maximum four bytes.

Hiperspace Buffers The number of hiperspace buffers used for the logical shared resource pool. The value format is an integer of maximum four bytes.

Hiperspace Reads Failed The number of hiperspace buffer reads that failed for the logical shared resource pool. The value format is an integer of maximum four bytes.

Hiperspace Writes Failed The number of hiperspace buffer WRITE requests that failed for the logical shared resource pool. The value format is an integer of maximum four bytes.

Lookaside Hits The number of successful read requests that VSAM was able to satisfy without initiating an I/O operation; that is, the requested index record was already present in one of the buffer resident Control Intervals. The value format is an integer of maximum four bytes.

Lookaside Ratio Indicates the percentage of VSAM read requests that were satisfied without initiating I/O because the Control Interval (CI) was already resident in the buffer pool. The value format is a percentage in the range of 0-100.

Non User Buffer Writes The number of non user buffer WRITEs for the logical shared resource pool. The value format is an integer of maximum four bytes.

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.

This value is computed by dividing the number of active strings by the total number of strings.

Pool ID Identifies the LSR pool. The value format is an integer of maximum two bytes.

Successful Hiperspace Reads The number of successful hiperspace buffer reads used for the logical shared resource pool. The value format is an integer of maximum four bytes.

Successful Hiperspace Writes The number of successful hiperspace buffer WRITE requests used for the logical shared resource pool. The value format is an integer of 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.
