What is the difference between Jcllib and Joblib?

What is the difference between Jcllib and Joblib?

JCLLIB points to a procedure library — human-readable, usually RECFM=FB 80-byte records that contain JCL statements. JOBLIB points to a load library — executable code that is not human readable, usually RECFM=U records that can be up to 32K long.

What is Joblib and Steplib?

JOBLIB and STEPLIB in JCL both are used to specify the load libraries so that that the programs that are being used in that JCL/JOB are searched in these libraries. Specifying JOBLIB/steplib makes the Z/OS to search in these libraries first and then in system libraries.

What is Jcllib?

A JCLLIB statement is used to identify the private libraries used in the job. It can be used both with instream and cataloged procedures.

What is SYS1 Proclib?

SYS1. PROCLIB is a required partitioned data set that contains the IBM-supplied JCL procedures used to perform certain system functions. The JCL can be for system tasks or for processing program tasks invoked by the operator or the programmer. One JCL procedure in SYS1.

What is the use of Joblib?

Joblib is part of the SciPy ecosystem and provides utilities for pipelining Python jobs. It provides utilities for saving and loading Python objects that make use of NumPy data structures, efficiently.

What is the function of Jcllib statement?

The JCLLIB statement allows you to code and use procedures and INCLUDE groups in a private library without the need to use system procedure libraries. You can code only one JCLLIB statement per job.

When to use JOBLIB and STEPlib in JCL?

JOBLIB: is used at the start of the JCL to specify and override library to use for the entire job. It is placed immediately after the job statement and applies to the whole job. STEPLIB: is used in an individual step in the job. It is placed immediately after the EXEC statement to which it applies to and is used only for that step.

What is the use of jcllib and proclib?

JCLLIB & PROCLIB: are used to specify where JCL is to be loaded from rather than programs. JCLLIB is used with the INCLUDE MEMBER statement to specify the libraries where pieces of JCL are held that can be included into a number of jobs. PROCLIB is the DD statement to override where to get procedures from.

What’s the difference between JCL and jcllib stmt?

JCLLIB ORDER is a JCL stmt that allows the user to specify his/her own proclibs and/or specify the order in which they’re searched to find the PROC (s) or INCLUDE libraries invoked in the JCL.

What is a load module in JCL-techtricky?

What is a LOAD Module: Load module is nothing but the executable code of a program which gets created in the compilation process (Link Edit part) and stored in a PDS specified in the compile JCL. These Load libraries are used in JOBs to execute the programs. To give more insight, we need to know about Source and Object Modules as well.
