What does REPRO REPLACE do?
When using REPRO, the REPLACE parameter lets you merge a backup copy into the damaged data set. With a fixed-length or variable-length RRDS, each source record, whose relative record number identifies a data record in the target data set, replaces the target record.
What is repro in idcams?
Repro. REPRO command is used to load data into VSAM dataset. It is also used to copy data from one VSAM data set to another. We can use this command to copy data from sequential file to VSAM file. IDCAMS utility uses REPRO command to load the datasets.
What is repro in VSAM?
The REPRO command lets you retrieve records from a sequential or VSAM data set and store them in VSAM format in a key-sequenced, entry-sequenced, relative-record, or a sequential data set. The REPRO command is also used to load data from one linear data set into another linear data set.
Can INstream data copied to KSDS?
IN the above example INstream data is copied to a KSDS cluster . The numbers 1.2 and 3 are the keys of those records. They should be in sorted order for KSDS file to accept it. This indicates that all data was copied properly to the KSDS cluster.
What is idcams JCL?
JCL – IDCAMS Utility IDCAMS stands for Integrated Data Cluster Access Method Services. IDCAMS utility is used to create, modify and delete the VSAM datasets. IDCAMS Utility is very useful utility to manipulate VSAM datasets.
Which of the following functions are performed by the repro command?
The REPRO command performs the following functions: Copies VSAM and non-VSAM data sets. If the data set is a version 2 PDSE with generations, only the current generation of each member is copied. Copies catalogs.
What is the purpose of the Verify function of IDCAMS?
The IDCAMS VERIFY command, with or without the RECOVER option, opens the data sets for output and updates the catalog when the command issues CLOSE. The VERIFY macro opens the data set for input and only updates the control blocks without updating the catalog.
Why is reusing better than recycling?
Reusing is better than recycling because it saves the energy that comes with having to dismantle and re-manufacture products. It also significantly reduces waste and pollution because it reduces the need for raw materials, saving both forests and water supplies.
What is IDCAMS mainframe?
IDCAMS stands for Integrated Data Cluster Access Method Services. IDCAMS is purely mainframe related utility which is used to process or manipulate VSAM datasets or no VSAM datasets with the help of JCL or other mainframe utilities which can run IDCAMS in background.
What is the use of IDCAMS utility?
IDCAMS utility is used to create, modify and delete the VSAM datasets.
What is the IDCAMS repro command used for?
IDCAMS- REPRO Command. REPRO command is used to copy data from one file (Input file) to another file (Output file) Input & Output file can be VSAM dataset (like KSDS, ESDS, RRDS etc.) or non-VSAM dataset (like PS file or a member of PDS). Using REPRO command, we can also merge data from two VSAM datasets. Important consideration:-.
How is the repro command used in VSAM?
REPRO command is used to copy data from one file (Input file) to another file (Output file) Input & Output file can be VSAM dataset (like KSDS, ESDS, RRDS etc.) or non-VSAM dataset (like PS file or a member of PDS). Using REPRO command, we can also merge data from two VSAM datasets
How to use repro command in mainframebug?
1 REPRO command is used to copy data from one file (Input file) to another file (Output file) 2 Input & Output file can be VSAM dataset (like KSDS, ESDS, RRDS etc.) or non-VSAM dataset (like PS file or a member of PDS). 3 Using REPRO command, we can also merge data from two VSAM datasets
Do you have to enable LBI to use repro?
(You enable LBI by coding any BLKSIZE value, in the DCBE macro or by turning on the DCBEULBI bit before completion of the DCB OPEN exit – see z/OS DFSMS Using Data Sets .) If you have LBI enabled, you can use REPRO with data sets with a blocksize larger than 32760 bytes.
