In modern times, there are two distinct implementations of the Job Entry System called JES2 and JES3. They are designed to provide efficient execution of batch jobs.These phases include input processing where jobs are read and interpreted, the execution phase where jobs run, and output processing where job output is printed or stored on DASD. Jobs that are in the same phase of execution are usually said to reside on a particular queue; for example, jobs that are currently executing are on the execution queue. JES uses a structure called a checkpoint to backup information about currently executing jobs and their associated output. The checkpoint can be used to restore jobs and output in the event of unexpected hardware or software failures.Because of these differences, one JES may be favored over the other in certain customer installations. JCL is used to define jobs to both JES2 and JES3, but small changes usually need to be made to the JCL to get a job written for one JES to run on the other.The HASP System, February 26, 1971 HASP II (360D-05.1-014) V3M1.

Simply put, Redbooks are really useful. Let me explain.IBM products are supported by product manuals. The table below is for JES2. Many of the product manuals are narrow in focus, for example Commands or Data Areas or reference in nature like Messages or Macros. Here are two examples:This IBM Redbooks publication provides information to help clients that have JES3 and want to migrate to JES2. It provides a comprehensive list of the differences between the two job entry subsystems and provides information to help you determine the migration effort and actions. It should be used with JES3 to JES2 Migration Considerations, SG24-8083. This makes them an attractive tool to get a job done using the product manuals mainly for reference.The IBM Redbooks web site is organized in five categories. Each category has sections, each of which contains a number of documents. The five categories—along with their respective sections and documents—include:It’s useful to count the documents in each category. Doing this, I discovered that there are over 3,565 documents. This body of work is a significant tool to build and maintain technical skills and to get a job done quickly. The numbers tell only part of the story.

At this point, JES3 users should consider the options discussed in this step. Before you start, verify that the exits you want to use are supported.http://www.raumboerse-luzern.ch/mieten/bosch-pfz-550-manual All tapes originally created with a CA 1 keyword expiration date will be rejected.With CA 1, it is not necessary to remove the write rings. For JES3 versions having IATUX62 (JES3 2.1.5 or higher), this user exit allows SL functions to be overridden. To turn on DEFER, you must modify both IATIIDY and IATIIP1 (see below). Turn on the following bits in the JDAB control blocks (DSECTed by the JES3 macro IATYJDA): See appropriate IBM documentation. Check sequence numbers, as they might change. Also, turn on DEFER for all tape mounts. Consult your IBM PSR. You only need to turn on DEFER for all tape mounts if you are going to be using scratch subpools. Consult your IBM PSR. The term “Broadcom” refers to Broadcom Inc. One of our customers wants to know whether it works in JES3 or not.I would like to know whether my script is Compatible in JES3. That's why I need help from someone who has the JES3 environment can verify this.JES3 commands are different so your JES2 commands will not work and your command will be processed on the system that the job was submitted on unless you specify differently (SYSAFF ???) so if you put a JES3 command in there you must make sure that the system affinity is set too or that the job is submitted on the JES3 system.Both are a waste of every resource. You will have to put it after the JOB statement. The initiator must allow commands, and the job userid must have operator command authority, the latter I think is identical to a JES2 system. You can enter (E)JES commands directly from these panels to manage job processes and the operation of system resources. Learn more about Zowe on GitHub. Phoenix Software now offers two Zowe Conformant (E)JES components, a REST API and a Plug-in for Zowe CLI. The APIML is a gateway that provides a single point of access to heterogeneous services that might be located on different systems or locations.http://jochenschild.com/images/c250-manual.pdf The CLI supports the concept of “plug-ins”, modules that can be incorporated into the CLI framework to extend the functionality of the basic “zowe” command. The CLI allows the plug-in to support a common syntax for command line directives, options and parameters. The (E)JES plug-in uses the API (E)JES Zowe REST API to provide command line functions to stream or search mainframe system logs. This has resulted in a modern interface that very closely replicates (E)JES response times under ISPF. All (E)JES displays are fully supported. Sorting, filtering, searching, and more are performed on the server where the data resides. The client is simply a user interface for requesting and viewing the results of these data manipulations. Dropdown and context-sensitive menus give users access to (E)JES displays as well as options that affect how data is presented on those displays. Most (E)JES Web features are discoverable and online help is available when needed. Users can select tabular rows and access line commands using only keyboard commands. Traditional 3270 users will find most of the keyboard commands in (E)JES Web instantly recognizable. Typing a single character invokes a command field at the bottom of the display where system, primary, and line commands may be issued. IBM message manuals describe the exact format (for example, spacing) and definition for each message. Ellipses indicate that the message contains more text than is shown. Do not suppress or alter them using products designed to handle messages through the subsystem interface (SSI). Many automated operations systems use the subsystem interface to intercept and alter or suppress messages. The use of other WTO exits to change the display characteristics or the text of these messages is not supported by the SMC. The action of the SMC is similar to the SMC actions for the normal MVS mount messages (for example, IEC233A, etc). These messages drives the dismount of the tapes mounted from the EDG6627A message.https://www.marthatrotts.ca/wp-content/plugins/formcraft/file-upload/server/content/files/1629ad3920659f---Corolla-s-2007-manual.pdf The following messages must be acted on by the SMC to dismount a tape: Legal Notices.

We want our books to be as helpful as possible. It will also be beneficial to organizations that have only JES3 and are considering migrating to JES2. In Part 1, we cover the information that you need to make a migration decision. In Part 2, we cover the information that you need to plan your migration. Perhaps one of your first questions is “Why would an enterprise want to convert to a different job entry subsystem”. As with any IT strategy, your decision will be based on a thorough analysis of the costs and benefits of migrating, based on the latest information. This book helps you identify what the migration effort would be. For some JES3 installations, the migration might be relatively easy, but for others it will be time-consuming and complex. It depends on the extent to which you exploit the capabilities that are unique to JES3. Positioning for migration Many of the issues that need to be addressed when performing a JES3 to JES2 migration pertain to the use of facilities that, at one time, were only provided by JES3. Over time, many of these facilities were provided by the operating system. However, naturally, people continue using things that they are familiar with. Even if you never migrate to JES2, it is a good idea to ensure that any new applications or new jobs avoid the use of facilities that are unique to a particular Job Entry Subsystem (JES). Most enterprises take a number of years to deliberate over whether they will perform the migration or not. During that time, you could potentially be creating many more things that will subsequently need to be addressed as part of the migration.alliedpers.com/userfiles/files/camry-user-manual-2009.pdf In the opinion of the authors, it is a very good investment of your time to put tools, documentation, and education in place now to ensure that your users (including operators, production schedulers, application developers, and system programmers) stop using mechanisms that are unique to JES3. If you have both JES2 and JES3 today, it is worth considering to stop using mechanisms that are unique to any JES. 6.1.1, “Positioning moves” on page 90 provides information about changes you can start making in advance of any migration. Additionally, throughout this book we point out changes that can be made now that will not impact current operations under JES3, but that will make the migration easier if you decide to go down that path in the future. Information provided in this book The book is divided into two parts. Part One gives you information to make your migration decision. Part Two gives you the information that you need to plan for your migration. The next chapter provides background information about how JES2 works. 2 JES3 to JES2 Migration Considerations 1 Chapter 1. How JES2 works When making a migration decision from JES3, you will want to know what JES2 provides. This chapter is intended for people who are familiar with JES3 and want to understand how JES2 works. It helps you to understand situations where the same function has a different name in JES2 than in JES3. In many ways, JES2 provides many of the same functions that JES3 does. However, it generally does them in a completely different way. These differences arose over the years, partly because of different functional requirements, but also because of a fundamental difference in philosophy. JES3’s basic philosophy is one of centralized control where one global system controls some number of local systems, freeing up the locals to do what is most important to them: run jobs. JES2 however, is a collection of peer systems that independently process and manage work on the input, execution, and output queues. The concept of a job entry system originated around 1960. Computers were constantly getting faster, but unit record devices (printers, card readers, and card punches) with their mechanical processes were getting slower relative to processor speeds. This meant you could run more jobs and make more efficient use of the expensive system. From this beginning, JES2 and JES3 evolved. The two products were originally designed to address different parts of the mainframe market, but over time their surface functions have been converging. 1.2 JES2 overview At its most basic level, JES2 provides the same functions as JES3 (or any other batch management system). It manages job and output work queues, implements a SPOOL to temporarily store data (job streams and SYSOUT data sets), and deals with peripheral devices (card readers, card punches, and printer). Jobs are generally submitted to JES from TSO using the SUBMIT command that writes card images to an internal reader. An internal reader is just a logical card reader. Job control language (JCL) is written in 80-character card images with room for sequence numbers in columns 73-80 (a carry-over from the days when you could drop your JCL card deck and had to get it back in the correct sequence). JES2 also supports input and output using network job entry (NJE) protocols and remote job entry (RJE). These are ways to connect other systems to JES2 either as peers (NJE) or as workstations (RJE). JES2 has an initialization deck that defines how JES2 will operate, operator commands that allow users and operators to interact with JES2, and programming interfaces such as the subsystem interface (SSI) that allow JES2 to communicate with other processes. Up to this point, the same description applies to both JES2 and JES3. So what is different about JES2. One of the big differences is philosophy (centralized control versus distributed). Another is the scope of the function provided. The two have a different command and initialization deck philosophy. It is these subtle items that make a world of difference in how the two JESs do the same basic processing so differently. The purpose of this chapter is to help you understand how JES2 does things and, where applicable, contrast that with how JES3 does things. The checkpoint can be placed in a DASD data set or in a Coupling Facility structure. JES2 can have 1 - 32 members accessing the checkpoint. All members must also have access to a set of data sets that contain the SPOOL data. A MAS (also referred to as a JES2 JESplex) is therefore the collection of JES2 members that access the same checkpoint and SPOOL data sets. You can have multiple JESplexes in a single sysplex, including JES2 and JES3 JESPLEXes in the same sysplex. JES2 supports being defined as a primary or a secondary subsystem. If JES3 is running on a system, it must be the primary job entry subsystem. You cannot run JES2 as the primary subsystem and JES3 as a secondary subsystem. A secondary JES2 can be in the same MAS as the primary or in a separate MAS. There are multiple reasons to run a secondary JES2. The first is for testing purposes. Some customers test user exits or JES2 service in a secondary subsystem that is in a separate MAS from the primary but with access to the production environment. Other customers use secondary JES2s with a separate MAS to move work off the production MAS due to capacity issues. One case of this was a customer that had a flood of SYSOUT data sets created in their production MAS. The number of SYSOUT data sets was overwhelming their production archiver, so they used NJE to transfer most of the SYSOUT data sets to a secondary MAS using NJE and then brought them back to the production MAS a few thousand at a time to be archived. A secondary JES2 in the same MAS as the primary has also been used to isolate functions (for reliability or performance). One example of this is placing SNA networking connections in a secondary JES2. Networking is CPU intensive for the JES2 main task but does not require access to the JES2 checkpoint. Moving it to a secondary JES2 allows frees up resources in the primary JES2 for other work. Each JES2 address space operates in a generally autonomous way. Most communication between JES2 address spaces traditionally occurs through the checkpoint data set. More recently, JESXCF is used to broadcast notifications and request specific functions from a member, and multi-system Event Notification Facilities (ENFs) are used to communicate job and outputs transitions. But the checkpoint is still the primary way JES2 members communicate. All members in JES2 are capable of performing all JES2 functions. There are some functions for which a single member acts as coordinator (such as a checkpoint reconfiguration or SPOOL configuration manipulation) and others that only get performed on one member (such as priority aging). In these cases, if the member coordinating or performing the function fails, the processing moves to another member automatically. Functions like RJE and NJE can be performed on any member of a MAS (including secondary JES2s). From an NJE point of view, the MAS is a single NJE node (just like JES3). NJE can be done between any two JES2s that are in separate MASes, including between a primary JES2 and a secondary one, or between two secondary JES2s. Of course, NJE can also be done between JES2 and JES3 or any other operating system that supports the NJE protocol. Though the externals that manage NJE are different between JES2 and JES3, the underlying code is the same. The JES2 address space is the started task that is created by the S JES2 command. As part of the initialization of JES2, two additional address spaces are created, JES2AUX and JES2MON (note that “JES2” is replaced with the actual subsystem name specified on the start command). The JES2AUX address space is the owner of various resources associated with JES2. It also runs some code to process requests from other MAS members. It cannot be canceled or forced. The JES2MON address space monitors the health of JES2 and ensures that it is processing normally. Chapter 1. How JES2 works 7 JES2 uses XCF messaging to communicate between members and to determine member status. Similar to JES3, JES2 uses JESXCF to manage this communication. The JES2 messages consist of smaller messages between all members of the MAS. This differs from JES3 where messages can be larger and are primarily between the global and the local. JES2 also uses messaging to transport unwritten buffers between address spaces for spool data set browse. A number of other optional address spaces are associated with JES2 based on functions used by JES2. Print processing can be done using the Functional Subsystem Interface (FSI). This interface, similar to the JES3 FSI, is used in JES2 to interact with products such as PSF. JES3 also uses the FSI for other processing, but JES2 only uses it for printing. If this option is active, the processing is done in a JES2CI address space. In addition to these address spaces, there is code that implements the JES2 side of the SSI and code that implements the SPOOL access method (known as HAM or HASP Access Method). Even when the JES2 address space terminates (such as when it ABENDs), these interfaces are still active. They continue to function so long as they do not require functions from the JES2 address space. If the requests require services from the JES2 address space (on that member), they will either wait for JES2 to be restarted, or fail the request. Whether an interface can continue to function without the JES2 address space depends on where the code that implements the function runs. This differs greatly between JES2 and JES3. For example, creating, opening, and writing to a SYSOUT data set does not require any processing in the JES2 address space. However, creating and writing to a SYSOUT data set does require spool space. Each address space has some spool space available from its last allocation of space and JES2 maintains a cache of spool space (called the BLOB) for use by running address space. If there is available space, address spaces can continue to create and write to SYSOUT data. But once that space is exhausted, the address space waits for spool space. Other functions always require the local JES2 address space to be active. For example, submitting a job, placing a job into execution, taking a job out of execution, processing a start command, or logging on to TSO all require services from the JES2 address space. But it is only the JES2 address space on the member where the request originated that must be active. Loss of a JES2 address space only impacts the work associated with that JES2, not work associated with other systems. When shutting down JES2, you can either stop just the JES2 address space or try to completely shut down JES2. The command is only accepted if there are no address spaces connected to JES2 and if there are no active JES2 processes. JES2 also will disconnect from the SSI. Often a clean shutdown of JES2 is not practical for the primary subsystem due to the number of address spaces that connect to JES2. But a secondary JES2 can more easily be shut down cleanly, allowing more possibilities for how secondaries are restarted. After a clean shutdown of all JES2 members of a MAS, the systems are in a state where an all-member warm start or even a cold start could be performed.
