ALLOCATE utility in z/VSE

Overview

The ALLOCATE utility provided with MODEL 204 allocates Model 204 files, including CCATEMP, CCAGRP, and CCASERVR, in the z/VSE environment. One or more files, as specified in control statements, can be allocated during one execution. You must provide a DLBL and EXTENT with complete information for each file name referenced in the ALLOCATE control statement.

ALLOCATE control statement

The ALLOCATE control statement format is:

ALLOCATE FILE (filename1 filename2 filenamex)

The following considerations apply:

• The ALLOCATE statement is free format and can begin in any column.
• You can include any number of ALLOCATE control statements in the input to the utility.
• Use a continuation character (-) after the last parameter on an input record being continued.
• There is no limitation to the number of continuation statements.
• filename1 through filenamex refer to the file names on the DLBL statements in the job control stream.
• If a file name referenced in the ALLOCATE statement control does not have a corresponding DLBL statement in the JCL, an error message is logged in the output audit trail.

ALLOCATE z/VSE job stream

The following job stream runs the ALLOCATE utility:

// JOB ALLOCATE MODEL 204 FILES // DLBL M204CL,'M204.CORE.IMAGE.LIBRARY' // EXTENT ,volser // LIBDEF CL,SEARCH=M204CL // DLBL CCATEMP,'CCATEMP.SCRATCH.FILE',0 // EXTENT SYS001,SYSWK1,,,1000,390 // DLBL CLAIM81,'DEMO.CLAIMS81',99/365 // EXTENT SYS001,SYSWK1,,,1390,780 // DLBL CLAIM82,'DEMO.CLAIMS82',,,99/365 // EXTENT SYS001,SYSWK1,,,1780,780 // DLBL CLIENTS,'DEMO.CLIENTS',99/365 // EXTENT SYS001,SYSWK1,,,3340,780 // DLBL VEHICLE,'DEMO.VEHICLES',99/365 // EXTENT SYS001,SYSWK1,,,4120,780 // ASSGN SYS001,DISK,VOL=SYSWK1,SHR // EXEC ALLOCATE,SIZE=AUTO *ALLOCATE DEMONSTRATION DATABASE FILES ALLOCATE FILE (CLAIM81) ALLOCATE FILE (CCATEMP - CLAIM82) ALLOCATE FILE (VEHICLE,CLIENTS) /* /&
