Defining the BIM-EPIC Environment Creating Disk Pool Statements
Chapter 2. Installing the Basic System 2-43
If start and end track or block addresses are not specified, they will appear as 0 and 15728641
on the TAID transaction’s pool display panel and on the TSIDDEB Summary Report until the
first allocation occurs on the volume after an IPL. The first allocation forces BIM-EPIC to
read the volume’s VTOC and set the start and end track or block addresses based on the
volume’s actual capacity.
vol-restriction can be used to place the volume in QUIESCE or OFFLINE status. If
QUIESCE is specified, BIM-EPIC will provide access to existing files on this volume but will
not allocate any new files to the volume. If OFFLINE is specified, BIM-EPIC will not
provide access to any files on this volume. You can also place a volume in QUIESCE or
OFFLINE status with TSIDMNT or Online Manager. Volumes can be placed online again
using the ONLINE function.
LEVEL specifies whether leveling is active for the pool.
POLNAME=numeric-poolname must be used to specify a pool name such as 111111. If
you use POLNAME=numeric-poolname, do not specify the poolname label before
TSIDPOL.
alias-name is used to specify an alias name for a pool.
The following example specifies that the areas from tracks 1 through 5000 on volume
SYSWK2, and from tracks 1 through 9500 on SYSWK3 will make up the pool known as
POOL01.
POOL01 TSIDPOL (SYSWK2,1,5000),(SYSWK3,1,9500),LEVEL=YES
The following example specifies that all space from track 1000 through the end of the volume
on volume WORK09, all space on volume WORK10, and all space on volume WORK11 will
make up the pool known as POOL02.
POOL02 TSIDPOL (WORK09,1000),(WORK10),(WORK11),LEVEL=YES
The following example defines alias names for POOL02 so that JCL references to POOL02
can be made with these names. By choosing pool aliases that are the same as the volsers used
to define POOL02, JCL that used to reference volsers can now reference entire pools.
WORK09 TSIDPOL EQU=POOL02
WORK10 TSIDPOL EQU=POOL02
WORK11 TSIDPOL EQU=POOL02
