STOP-X37EX/STOP-SPDTS Software, LLC.
Automatically avoids the space-related abends that occur on operating systems.
There is no longer any need to fear x37 abends. Now you can finally sleep soundly at night.
STOP-X37EX/STOP-SP (STOP-X37EX hereafter) is software that automatically recovers abends that occur on operating systems—specifically, x37 abends (completion codes B37, D37, and E37) that indicate a lack of DASD space. It runs as a frontend of the EOV (end of volume)/SVC module and performs recovery processing for jobs that is attempting an abend.
Main Features
| Feature | Recovery method |
|---|---|
| REDUCEP | When a primary allocation space for new data set specified by the DD statement of JCL cannot be secured, REDUCEP secures space by adjusting the primary allocation according to the situation. |
| REDUCES | When the secondary allocation space specified by the DD statement of JCL cannot be secured, REDUCES secures space by adjusting the maximum free space value within the volume that is currently using that value. |
| SETSEC | When there is no secondary allocation specified in the DD statement of JCL, SETSEC secures space by adding a secondary allocation. |
| ADDVOL | If expanding a sequential data set to 16 extents is still not enough, ADDVOL adds a new volume to allow further extent expansion. |
Optional Features
| Feature | Recovery method |
|---|---|
| RECAT | RECAT (RECATalog option) operates as a frontend of the operating system’s deallocation program and recovers the "NOT CATLOG 2" (JOBLOG message) condition that occurs when an attempt is made to re-catalog a dataset that has already been cataloged. |
| VSAM | VSAM allocates an additional volume when the "OUT OF SPACE" condition occurs in a VSAM data set that uses the ICF catalog. |
Operating Environment
| Vendor | OS |
|---|---|
| IBM Fujitsu Hitachi |
OS/390, z/OS MSP/E20, MSP/EX VOS3/AS, VOS3/FS, VOS3/LS, VOS3/US |
Batch utility
STOP-X37EX offers the following batch utility.
SRSSMF: Analyzes and reports recovery status from SMF records after STOP-37EX deployment.
Rule language
STOP-X37EX is easy to use and controlled by a flexible rule language. These parameters can be specified to select which job is subject to the recovery process: dataset name, job name, DD name, device type, dataset organization, program name, and others.
Example:
DEFRULE A1
IF CLASS=I
JOBNAME=PROD*
THEN SET DIKPOOL=A1POOL
DEFPOOL A1POOL REDUCES(YES)
When the secondary allocation space specified by JCL cannot be secured in a class I job that starts with job name PROD, space will be secured by adjusting the secondary allocation according to the situation.
