Using the Tape Retention System (TRS) › Retention Control Statements › Identifying the Data Sets › Adding Further Qualification

Adding Further Qualification

• You can use the JOB parm to identify the job that created the data set. This is optional. Coding the job name lets you define different retentions for the same data set when it is created by different jobs. For example, a demand deposit job at a bank might create a daily master file called DDA.MASTER.FILE which must be kept five days; the job that creates this file is named DDDAILY. The same application has a monthly job that creates the same master file but the three most current copies must be kept; the job that creates this file is named DDMNTHLY. By adding the job name to one of the definitions, you can define the retention of these two data sets on separate statements. One definition could keep the daily version of DDA.MASTER.FILE for five days; the other definition could keep the monthly version for three cycles:

• Use the OWNER parm to identify the individual or group who created or last updated this control statement. This is required.

A complete statement will look like one of these:

ADDRTN DSN(DDA.MASTER.FILE)   OWNER(JOHN DOE) +
       RTN(5DC0005)	
ADDRTN DSN(DDA.MASTER.FILE)   JOB(DDMNTHLY)  OWNER(JOHN DOE) +
       RTN(4DC0003)
