PROFILE_PATH

The full path where the profile is located.

RUN_DATE

Date when the reporter processed the sample data set output from the measurement session to create the performance profile.

RUN_TIME

The time when the reporter processed the sample data set output from the measurement session to create the performance profile.

RUN_TS

The timestamp when the reporter processed the sample data set output from the measurement session to create the performance profile.

FOLDER_NAME

The name of the folder where the profile file is located.

ASID

The address space identifier of the active job.

CONDITION_CODE

Condition code is code generated when the target program terminated normally while it was being measured.

DB2_SYSID DB2

The subsystem ID.

REGION

The name of the job under which the target program or subsystem was executed.

JOB_NUMBER

The Job Entry Subsystem (JES) number of the target job.

LPAR

The name of the logical partition in which the target job executed.

MEAS_RELEASE

The release of the components of Strobe that gather performance data about the measurement application.

PROGRAM_NAME

The name of the program or subsystem that was the target of the measurement session.

SESSION_DATE

The calendar date on which Strobe began measurement.

SESSION_TIME

The time of day at which Strobe began measurement.

STEP

The name of the job step, or of the procedure step and job step, in which the program or subsystem was executed.

SYSTEM_ID

The MVS system on which the measurement session was performed.

SESSION_TERM

Contains the error code when measurement session gets terminated prematurely due to some exception.

SQL_QUERY_NAME

The name of the SQL Query.

QUERY_TYPE

The type of SQL query.

SQL_QUERY_DTM

This shows :

a. If the report is for a Package, the date and time the Package was created.

b. If the query was executed once, the date and time that the query was executed.

c. If the report is for a SPUFI file, the date and time that the SPUFI file was executed.

d. If the procedure was executed once, the date and time that the procedure was executed.

AVG_TM

Shows the average time the statement took to execute during the measurement session.

ACCUM_AVG_TM

Shows the  total CPU time in seconds used by the SQL statement divided by the SQL statement count.

TOTAL_CPU_PERCENT

Shows the percentage of CPU activity with or without any concurrent I/O activity for the transaction.

INDB2_CPU_PERCENT

Shows the percentage of in_DB2 CPU time used by an SQL statement.

PAGE_WAIT_PERCENT

Shows the percentage of wait time incurred by the query without concurrent wait or other I/O activity.

TOTAL_WAIT_PERCENT

Shows the percentage of wait time associated with the query as a percentage of all wait time associated with the measured job step.

PARALLEL_TOTAL_CPU

Shows the CPU time in seconds executed in parallel processing on all processors for the SQL statement.

PARALLEL_SP_CPU

Shows the CPU time in seconds executed on a specialty processor such as a zIIP while in parallel processing for the SQL statement.

OVERALL_TOTAL_ELAPSED_TM

Shows the accumulated seconds taken to execute the SQL statement.

OVERALL_TOTAL_CPU_TM

Shows the accumulated CPU seconds taken to execute the SQL statement on all processors for parallel and non-parallel processing.

STMT_TYPE
