VX/JSP - OpenVMS Print & Batch

Description:

VX/JSP is a fully compatible implementation of the VMS/OpenVMS Batch and Print Queue Manager, providing both API and command-line interface support for Linux and Windows. Designed as an add-on module for VX/DCL, it enables job and print queue management, ensuring seamless execution of batch processing and printing operations outside of the VMS environment.

By replicating VMS batch and print capabilities, VX/JSP ensures that organizations migrating critical VMS workflows can retain identical functionality on Linux and Windows, including queue management, job control, and print device mapping.

Key Features

• Fully integrated with VX/DCL for command-line execution.

• Supports VMS/OpenVMS batch and print queues, including SUBMIT and PRINT commands.

• Implements SYS$ API calls for queue management:

• SYS$GETQUI

• SYS$GETQUIW

• SYS$SNDJBC

• SYS$SNDJBCW

• Allows job scheduling, priority control, and queue management.

• Supports advanced printing options, including restartable jobs and queue reordering.

• Maps VMS devices to Linux equivalents, ensuring printer compatibility.

PRINT QUEUES: Full VMS Print Job Support

VX/JSP includes over 100 print qualifiers, enabling advanced print job control for Linux and Windows environments.

• Supports restarting reports on specific pages.

• Queue reordering and job prioritization.

• Print to Linux-connected devices or spoolers.

• Direct printer connections or mapped network printers.

BATCH QUEUES: Job Scheduling and Execution

VX/JSP enables batch job submission via VX/DCL, ensuring VMS-like batch processing on Linux and Windows.

Key Features of VX/JSP Batch Processing

• Submit jobs using the SUBMIT command, executing DCL command files within VX/DCL.

• Define queue priorities and scheduling intervals for optimized execution.

• Simultaneous multi-job execution on a single queue.

Example:

$ SUBMIT jobfile.com /QUEUE=MYBATCH /PRIORITY=5 /AFTER=22:00

VX/JSP retains the original VMS syntax, allowing for no-modification migration of batch scripts.

Sample Queue Display Output

VX/JSP retains the VMS queue listing format, ensuring familiar queue management for migrated environments.

$ SHOW QUEUE/FORM
Form name     Number   Description
------------  ------   -----------
DEFAULT        0      Standard paper
TESTFORM_A     1      Green
TESTFORM_B     2      Red

Print queue SYS$PRINT, running, on LP:, mounted form TESTFORM_B
/PRIORITY=0 /NOENABLE_GENERIC
/DEFAULT=(NOFEED, FORM=TESTFORM_B) /STOCK="Private stock 2"

$ SHOW QUEUE/FULL/ALL
Jobname   Username   Entry  Status
--------  ---------  -----  ------
TESTCALL  Sector7     1    pending
Submitted Tue Sep 1 22:35:02 /FORM=TESTFORM_B (stock=Private stock 2) /PRIORITY=0
FILE: [tmp.test1]TESTCALL.COM;1

VX/JSP Batch & Print Queue Commands

VX/JSP supports all major VMS queue management commands, ensuring no syntax changes are required for migrated workloads.

Command	Description
DEFINE	Set up queue and form definitions.
INITIALIZE/QUEUE	Initialize a new queue.
PRINT	Submit a print job.
SUBMIT	Submit a batch job.
DELETE /ENTRY	Remove a job from the queue.
SET QUEUE	Modify queue attributes.
SHOW QUEUE	Display queue status.
START/QUEUE	Start a queue.
STOP/QUEUE	Stop a queue.

These commands allow for full queue management, ensuring that VMS-like job scheduling and printing continue working without modification.

Conclusion

VX/JSP is a critical tool for migrating VMS batch and print job processing to Linux and Windows.

✅ Fully compatible with VMS batch and print queue commands

✅ Implements all major SYS$ queue management API calls

✅ Supports advanced print and job scheduling options

✅ Integrated with VX/DCL for seamless migration

By ensuring identical batch and print queue operations, VX/JSP eliminates the complexity of migration, allowing organizations to maintain their workflows on modern platforms without code rewrites or retraining.
