eavJES provides you with the ability to replatform JCL and procs for batch execution with very little change. With eavJES, developers can continue to maintain the JCL and procs according to existing JCL rules. Execution results in the same actions, cataloging, restart, and recovery as on the mainframe. The catalogue is constantly monitored and maintained during job execution and can even allow command-line manipulation of datasets.

Why modernise?
CHALLENGES
Exorbitant costs
Mainframes cost as much as 4,500 percent more to operate than equivalent Cloud counterparts. This figure is compounded by a scarcity of development resources and rising licensing and maintenance fees for ancillary mainframe utilities, applications, and databases.
Limited data accessibility
Legacy databases are difficult to integrate with systems on modern platforms. This is because of inherent inextensibility, incompatibility, and rigidity of the underlying hardware and software powering these legacy systems.
Limited flexibility
Companies are rapidly moving to DevOps and the Cloud while consolidating their technology stacks to maximise IT performance. Unfortunately, the inflexibility of mainframes has become a growing hindrance to modern, continuously evolving, agile business.
eavJES batch execution
OUR SOLUTION
Our eavJES batch execution suite provides a system for organisations who want to preserve their JCL and procs, and continue to maintain them even when they move off the mainframe. eavJES supports COBOL, Natural, JCL and procs, C#, and Java, and can run as an ancillary to ATP, ModPaaS, or as a stand-alone utility. It enables batch execution in a Windows or Linux environment with a back-end database for the batch file catalogue, and comes pre-packaged with a myriad of utility replacements (JESBR14, JESCAMS, JESEMAIL, JESFTP, JESGENER, JESSORT). The catalogue is constantly monitored and maintained during job execution and can even allow command-line manipulation of datasets.
The eavJES Initiator setup allows jobs to be classed and executed as they are on the mainframe. Job classes can be given different priorities with a limited number of initiators for each type, and message class setup allows output for a class to be automatically transitioned to PDF output or to email. Load libraries can be sequenced for each eavJES environment so that the proper load modules are executed for that batch region, while storage units can be defined to reflect the different storage types that were used in the original mainframe environment.
eavJES also contains a function that allows jobs to be pre-scheduled for submission at a specific time or upon an occurrence of a pre-defined event. Additionally, eavJES listeners provide the ability for other processors to submit a batch job remotely in the same manner as internal reader submission on the mainframe. For maximum visibility, our eavJES monitor provides operations and development teams with the ability to monitor jobs, change priorities, review outputs, and perform other batch management.
Over 35 years of Natural and mainframe modernisation experience
More than 500 successful modernisation projects completed
Over 2.5 billion lines of code refactored through automation
“We were looking to accomplish two things with the pilot. The first was to prove the solution would work on GE hardware under our roof. The second was to prove beyond a shadow of a doubt to our users that their UI wasn’t going to change.”
