J2U - A COMPLETE BATCH RUNTIME SYSTEM FOR DECENTRALIZED SYSTEMS AND Z/LINUX
Migration of z/OS batch applications in a decentralized environment without changing JCL also for z/Linux
J2U provides JESx functionality via z/OS in a decentralized environment. In the J2U runtime environment, each available z/OS batch job can be carried out without modification on the new target platform Unix, Linux, z/Linux or Windows (optional).
To this end, J2U interprets the JCL and carries it out according to the same rules used via z/OS. The value contained within the JCL domain logic remains unchanged as a result.
To put it briefly: With J2U, your batch production runs just like before but on a different platform.
Business-wide batch runtime environment with standards maintained across all platforms
J2U supports the management of job progress alongside JCL and other scripting languages and, as a result, presents a business-wide integration platform for your batch applications. The following maintained standards apply:
- Security integration analogous to RACF, optional with connection from LDAP
- File organization and administration including a central catalogue and an HSM emulation with tiered storage
- Log and output management including archiving and connection to printing systems
- Supports various job schedulers
- Emulation of z/OS Utilities
Cross-platform log and output management
Alongside log and output files produced by J2U, files can be imported to J2U. To this end, J2U provides an integration platform that unifies and simplifies central administration from both an organizational and a technical point of view.
- Definition and monitoring of storage periods
- Definition and execution of post-processing for job output (report creation)
- Integrated archiving function in file system
- Integrated interface for diverse archiving, i.e., back-up systems
- Integrated authorization check
Job Control Search
The Job Control Panel provides access to jobs and the log archive. It contains functions to search through jobs and managing job-log files. The integrated monitoring functions enable the monitoring of jobs in progress.
Access is generally via the search page with comprehensive selection criteria for a detailed selection of jobs
Job Control List of Results
The Job Control List of Results shows matches to the selected search criteria. The list also contains information to the job such as job number, start and end timestamp, the current status, return code, and job-group category.
Authorizations for displaying and adjusting entries is defined via the job group.
Depending on the return code, completed jobs can be found and manually marked in the input or error queue or by changing the Job Control Details so that jobs are displayed as “Reviewed”.
Job Control Details
The individual log files for each job are listed under Job Control Details. Alongside the relevant job step with the corresponding return code step, the current archiving status is displayed.
Log files already archived in the backup system can be recopied via the Control Panel.
The log file can be displayed either by changing the file contents or by clicking on Download and saved locally.
Job Control File Content
The selected log file is shown under File Content. Log files have a structure familiar to JESx via z/OS and are continually updated in the case of an ongoing job.
In addition to the display, this window can also trigger a resubmit, i.e., the job can be started again.
Output Archive Search
The Output Control Panel provides access to the lists and the Output Archive. It contains functions to search through and manage lists.
Access is generally via the search page with comprehensive selection criteria for a detailed selection of lists.
Output Archive List of Results
The Output Archive List of Results shows matches to the selected search criteria. Authorizations can be set according to list definitions. Entries to list definitions made by unauthorized users are not maintained.
The current archiving status of each list is displayed. Lists already archived in the backup system can be recopied via the Control Panel.
The list can be displayed either by changing the file contents or by clicking on Download and saved locally.
Quick, easy, risk-free migration (in part or in full) of batch applications
There are no changes to the domain guidelines governing your batch production such as to the logic and behavior of individual steps within jobs and within job networks. That minimizes the risk and duration of a migration.
Reduction of expenditure on maintenance of batch applications through business-wide standards
Standards for batch processing that have stood the test of time via z/OS over decades are provided by J2U on the centralized platform, also enabling the management of any batch applications. Transfer of these standards to newly developed batch application, such as within a Java-based system, contribute to the consolidation and thereby to the reduction of maintenance expenditure.
Unified job, log, and output management of all platforms, meaning lower operational costs
With central job, log, and output files, JTU presents the decentralized world with an integration platform for the access and connection to further processing systems.
With J2U, your production planning and management gets a tool that simplifies the monitoring and, in particular, problem analysis in the case of error, thereby improving the efficiency of your employees.
Cost savings through the replacement of third parties
The log and output management integrated into J2U includes functions that can fully meet customer demands.
Cost-intensive implementation of third-party products is no longer necessary.
