What is the difference between Iebgener and Iebcopy?
IEBGENER – This is a dataset utility for copying sequential dataset which produces a PDS or a member from a sequential dataset. IEBCOPY – This is a dataset utility for copying one PDS to another or to merge PDSs. REPRO – This is for copying sequential datasets.
What is Iebgener in mainframe?
The IEBGENER utility is a copy program that has been part of the operating system since the first release of OS/360. One of its many uses is to copy a sequential data set, a member of a partitioned data set (PDS) or PDSE, or a z/OS® UNIX® System Services (z/OS UNIX) file such as a HFS file.
What is the function of Iebcopy?
IEBCOPY is a data set utility that is used to copy or merge members between one or more partitioned data sets, or partitioned data sets extended (PDSEs), in full or in part. More specifically, this utility is commonly used for several purposes: To copy selected (or all) members from one partitioned data set to another.
How do I copy selected members from one PDS to another?
To move a single member from one PDS to another, enter the complete information (including member name) in the From ISPF Library section of the Move/Copy Utility panel. Then type M on the option line and press the Enter key. To try a simulation of moving a member from one data set to another, click the Launch button.
What is SYSUT1 and SYSUT2 in JCL?
jcl) uses IEBGENER to submit a second job via the Internal Reader (INTRDR). The IEBGENER utility is commonly used to copy one sequential data set to another. The file to be copied is SYSUT1 and the output file is SYSUT2. A JCL member of a partitioned data set (PDS) can be defined by SYSUT1.
How do I transfer data from one dataset to another in mainframe?
To copy one data set to another, select the MOVE/COPY option (option 3). On the next panel, the Move/Copy Utility panel, specify the name of the data set from which you want to copy. For information about specifying data set names, refer to Specifying a Data Set Name.
How is GDG defined in JCL?
Defining GDGs in a JCL. Generation Data Groups (GDGs) are group of datasets related to each other by a common name. The common name is referred as GDG base and each dataset associated with the base is called a GDG version. For example, MYDATA.
How do I copy a user from one PDS to another in JCL?
IEBCOPY in JCL with Examples
- IEBCOPY is a copy utility that is used to perform copy functionalities for PDS and PDSE datasets.
- Copy all or Selected members from one PDS to another.
- Create multiple PDS in a single IEBCOPY job from one input PDS.
- Compress PDS to release the unused space.
What is the use of IEFBR14 in JCL?
The utility program IEFBR14 performs no action other than return a completion code of 0; however, “running” this utility invokes other system components that perform useful tasks. For example, submitting JCL to run IEFBR14 causes the z/OS® job scheduler to check your JCL statements for syntax errors.
What is DD * in JCL?
JCL statements: What does the DD statement do? Reusable JCL collection. Data definition (DD) statements define the data sets that a program or procedure uses when it runs. You must code one DD statement for each data set that is used or created within a job step.
What is Sysprint in JCL?
The SYSPRINT DD statement defines the output data set containing the end-of-step reports and any error messages. Normally it defines a SYSOUT data set. If the SYSPRINT DD statement is not in the JCL, the output of SYSPRINT is dynamically allocated to the default SYSOUT class—normally MSGCLASS.
How do you copy multiple lines in JCL?
To copy a block of lines within the same data set or member:
- Type CC in the line command field of both the first and last lines to be copied.
- Use the A (after), B (before), or OO (overlay) command to show where the copied lines are to be placed.
- Press Enter.
How do I backup a mainframe DataSet?
Creating Backup Versions of Data Sets or Volumes
- Dump single volume, multivolume, and VSAM data sets.
- Dump to tape or DASD.
- Specify allocation values for the new data set.
- Determine the disposition of the output data set when the dump is successful or if it is unsuccessful.
- Dump multiple copies of data sets.
What is the maximum limit of GDG?
LIMIT specifies that the maximum number of GDGs in the group is 255.
How do you skip steps in JCL?
COND parameter is JCL can be used to skip a step based on the return code from the previous step or steps of the JCL. 2. This COND parameter can also be used to skip a step based on the return code from a previous step or steps in PROC.
What is MOD Delete Delete in JCL?
A convenient and widely used method of deleting possibly-nonexistent data sets is specification of DISP=(MOD,DELETE,DELETE) in JCL. If the data set exists, it is found in the catalog and deleted. If the data set does not exist, it is created and then deleted.
How many steps a JCL can have?
How many steps can be executed in a JCL? A job has a maximum of 255 job steps. This will include all the steps in any procedure.
What is Sysda in JCL?
UNIT=DASD | SYSDA
Where DASD stands for Direct Access Storage Device and SYSDA stands for System Direct Access and refers to the next available disk storage device.
What is DD dummy in JCL?
The sustem understands whatever you tell it in the jcl (i.e. dcb info). DD DUMMY is used to make sure a ddname is resolved even though there is no actual input/output associated with this execution.
What is difference between Sysprint and Sysout?
SYSOUT is always allocated and gets among other things all the output from the System level process (including any messages about the JCL itself, performance stats, error messages etc.) SYSPRINT is just another DD which, by convention, is used by utility programs for thier output.
How do I paste a line in JCL?
To copy one or more lines within the same data set or member:
- Type C in the line command field of the line to be copied.
- Next, specify the destination of the line to be copied by using either the A (after), B (before), or O (overlay) line command.
- Press Enter.
How do you continue a line in JCL?
1. JCL rules to continue in the next line. First, break the parameter field after the comma that follows a parameter or sub-parameter (don’t forget to code the final comma at the end of the continued line). Second, code slashes in columns 1 and 2 of the following line.

How increase GDG limit in JCL?
If you use the access method services ALTER command to increase the GDG limit, no rolled-off GDSs or deferred roll-in GDSs are rolled in. When you increase the GDG limit, you must use the ALTER ROLLIN command to roll in the rolled-off generations if you need to access them.
