FILE: DAA Data Set Allocation File SAS FILE NAME: DETAIL.VCADAA01 SOURCE LOCATION: prefix.MICS.USER.SOURCE(DYVCAEXC) SEVERITY: Warning (SEVERITY='W') MANAGEMENT AREA: Performance (MGMTAREA='PERFORMANCE') PURPOSE: Identifies when a large data set is over-allocated. RATIONALE: Inefficient use of DASD space can impact the installation's ability to satisfy future DASD space requests. Large data sets that are static in nature should be allocated such that most of the space allocated is being used. If these data sets are over-allocated, the unused space is not available for use. DEFINITION: This exception is detected when the data set's allocation exceeds the specified value and the percent of allocated space in use falls below the specified minimum. EXCEPTION STATEMENTS: The SAS statements identifying the exception situation and describing the condition are stored in the source member named in SOURCE LOCATION and are described below: /*---------------------------------------------------------*/ /* */ /* 09010 */ /* DATA SET USING LESS THAN N% OF ALLOCATED SPACE */ /* */ /*---------------------------------------------------------*/ PERCENT = percent; SPACA = spaca; IF DAASPACA GE SPACA AND DAAPCSPU LT PERCENT THEN DO; EXCCODE='09010'; SEVERITY='W'; MGMTAREA='PERFORMANCE'; EXCDESC1='DATA SET USING ONLY' || PUT(DAAPCSPU,3.) || '% OF ALLOCATED SPACE'; EXCDESC2='VOL=' || VOLSER || ', DSN=' || DSNAME; LINK HIT; END; THRESHOLD MODIFICATION: The user should modify the percent and space values according to the following conventions: percent - The minimum acceptable value of allocated space that is in use. A minimum space utilization of 40 percent would be specified as: PERCENT = 40; spaca - The number of allocated tracks that is considered a large allocation. An allocation of 1000 tracks would be specified as: SPACA = 1000;
