What is the use of Icetool in JCL?
ICETOOL is a multi-purpose DFSORT utility used to perform a variety of operations on datasets. Input and output datasets can be defined using user defined DD names. The file operations are specified in the TOOLIN DD statement. Additional conditions can be specified in user defined ‘CTL’ DD statements.
What is the difference between Dfsort and Syncsort?
DFSORT is an IBM product. Syncsort is a Syncsort product. Syncsort documentation is available to organizations who license the product. If your organization is licensed, all of the material is available for free from Syncsort support.
How does Icetool splice work?
- SPLICE operator joins specified fields together from records with the same values (duplicate values) but with different information in other areas.
- It combines specified fields from two or more records to create an output record.
- The fields to be joined can originate from different datasets.
What is IBM Icetool?
ICETOOL is a multipurpose DFSORT utility that uses the capabilities of DFSORT to perform multiple operations on one or more data sets in a single step. This chapter introduces you to ICETOOL’s 17 “operators”, which allow you to do a wide variety of tasks.
How do you SORT with Icetool?
CTL1CNTL DD * – Specifies the DFSORT statements for processing. SORT FROM(INDD) TO(OUTDD) USING(CTL1) – Sorts the indd records and copies to OUTDD based on the selection criteria in CTL1. SORT FIELDS=(50,2,CH,A) – Sorts the records in ascending order based on the data of length 15 from 6th position.
Why do we need Joblib in JCL?
A JOBLIB statement is used in order to identify the location of the program to be executed in a JCL. The JOBLIB statement is specified after the JOB statement and before the EXEC statement. This can be used only for the in stream procedures and programs.
What is the difference between Icetool and sort?
ICETOOL is an expansion to DFSORT that allows users to do multiple operations in a single step, as well as perform additional new functions such as SELECT, SPLICE, OCCUR, DISPLAY, COUNT, STATS, VERIFY, etc. ICETOOL is supplied as part of the basic SORT package — if you have DFSORT, you also have ICETOOL.
What is SyncSort in mainframe?
SyncSort is a high speed replacement for the IBM SORT program. The SORT program is used to sort data into a certain sequence or to merge from two to sixteen previously sorted input data sets into one output data set. A rich set of data selection and modification tools also are also available.
How do you sort with Icetool?
How do I count the number of records in an Icetool file?
Sets RC=0 if the record count is equal w. Sets RC=12 (or RC=8 when RC8 is specified, or RC=4 when RC4 is specified) if the record count is equal to w….
- Subtracts a value from the derived record count.
- The record count is set to 0 if SUB reduces the record count below 0.
- ‘q’ value can be between 1 to 999.
How do you write a matching record in JCL?
JCL SORT to join two files and writes records from both files :
- Matched Records (Inner Join) –
- Matched Records and Non Matched Records from File1 –
- Non Matched from File1 –
- Matched Records and Non Matched from File2 –
- Non Matched from File2 –
- Matched Records and Non Matched Records from both files –
What is difference between Jcllib and Joblib?
Joblib is a default load library for all the jobsteps while jcclib is the loadlib that contains catalogued procedures.
What is difference between Steplib and Joblib?
What is the difference between the JOBlIB and the STEPLIB statements? The JOBlIB statement is placed after the JOB statement and is effective for all job steps. It cannot be placed in a cataloged procedure. The STEPLIB statement is placed after the EXEC statement and is effective for that job step only.
What is overlay in JCL?
Overlay lets you change specific existing columns without affecting the entire record.
What is Dfsort in mainframe?
DFSORT is a program you use to sort, merge, and copy information. When you sort records, you arrange them in a particular sequence, choosing an order more useful to you than the original one. When you merge records, you combine the contents of two or more previously sorted data sets into one.

How do I count records in a mainframe file?
Or just use a COPY and look at the job output to see how many records SORT found or use the COUNT function of SORT….COUNT Function: Count number of records in a file
- RC=12 if RC12 is specified, or by default if RC8 and RC4 are not specified.
- RC=8 if RC8 is specified.
- RC=4 if RC4 is specified.
How do I find out how many records are in a file?
Using “wc -l” But one of the easiest and widely used way is to use “wc -l”. The wc utility displays the number of lines, words, and bytes contained in each input file, or standard input (if no file is specified) to the standard output.
How do I compare two mainframe files?
Follow these steps:
- Open the Browse Dataset screen, Option 1 from the main menu.
- Identify the data set and member that contains your compare JCL.
- Press Enter. The compare JCL you have stored in the member displays.
- Type sub to submit your job for batch processing. A message confirming your submission displays.
What is Steplib and Joblib?
JOBLIB tells z/OS to search the private libraries for each step in the job. STEPLIB tells z/OS to search the private libraries only for one step.
