Locates Found in Pool Indicates the number of locate requests where the page was found in the pool. Valid value is an integer.

Locates Found in Pool Extended Precision Indicates the number of locate requests where the page was found in the pool (64 bit). Valid value is an integer.

Locked Buffers Indicates the number of buffers locked in pool due to I/O errors. Valid value is an integer.

Message Ident This identifier ties a group of messages to a specific table. Valid format is a text string of up to four alphanumeric characters.

MVS ID The MVS System Management Facility (SMF) identifier. Valid format is a text string of up to four alphanumeric characters.

Originating System Identifier Fully identifies the originating IMS subsystem. Valid format is a text string of up to 32 alphanumeric characters. Example: I91A:SP22:IMS

Prefix PageFixed Indicates whether the prefix is page fixed or not. Valid values include Yes, No, All, Mixed, and None.

Purge Calls Indicates the number of purge calls. Valid value is an integer.

Purge Calls Extended Precision Indicates the number of purge calls (64 bit). Valid value is an integer.

Purge Write Requests Indicates the number of blocks written by purge. Valid value is an integer.

Purge Write Requests Extended Precision Indicates the number of blocks written by purge (64 bit). Valid value is an integer.

Steal Wait Busy Release Indicates the number of buffer Steal or purge requests waiting for ownership to be released. Valid value is an integer.

Steal Wait Busy Release Extended Precision Indicates the number of buffer Steal or purge requests waiting for ownership to be released (64 bit). Valid value is an integer.

Steal Wait Busy Writing Indicates the number of buffer Steal waits for buffer busy reading. Valid value is an integer.

Steal Wait Busy Writing Extended Precision Indicates the number of buffer Steal waits for buffer busy reading (64 bit). Valid value is an integer.

Steal Wait No Buffer Indicates the number of buffer Steal waits due to no buffers being available. Valid value is an integer.

Subpool Number Identifies the subpool. Valid value is an integer or is enumerated to "Summary", if zero.

Summary Flag Used in predicates to allow you to control whether summary data is returned for all subpools. Valid values include Y for summary only, N for no summary, and B for both (the default setting).

Timestamp The date and time when the monitoring agent retrieved the data. This attribute is intended for logging and reporting data collection times rather than for creating situations. To specify a time of day for monitoring, use attributes from the Universal Time or Local Time groups. See the Tivoli Enterprise Portal help for instructions on specifying timestamp attributes in situations and queries.

Total I/O Errors Indicates the total number of errors associated with input/output activity. Valid value is an integer.

Total Storage Indicates the total amount of storage allocated for subpool. Valid value is an integer.

Write Requests Indicates the number of single block writes by buffer steal routine. Valid value is an integer.

Write Requests Extended Precision Indicates the number of single block writes by buffer steal routine (64 bit). Valid value is an integer.
