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.
Which utility can you use to copy a PDS?
The IEBCOPY utility: Copy libraries (partitioned data sets) 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.
What is Iebedit utility in JCL?
IEBEDIT. Used to copy selected parts of a JCL. For Example, if a JCL has 5 steps and we require to execute step 1 and 3 only, then a IEBEDIT JCL can be coded with a dataset which contains the actual JCL to be executed. In the SYSIN of IEBEDIT, we can specify STEP1 and STEP3 as parameters.
How do you end a JCL?
The JCL NULL statement is used to mark the end of a JCL. Furthermore, it denotes two forward slashes in the first 2 columns and leaving the rest of the columns after that as empty. This means, if you place ‘//’ in column 1 and 2 and keep other columns as empty, then it is treated as a Null Statement in JCL.
What is the output data set for IEBGENER?
The output data set for IEBGENER, as specified in SYSUT2, can contain fixed, variable, undefined, or variable spanned records (except partitioned data sets or PDSEs, which cannot contain variable spanned records). IEBGENER can reblock records if you specify a new maximum block length on the SYSUT2 DD statement.
Why does IEBGENER truncate my data?
Note: If you are using IEBGENER with an SMF dump data set, IEBGENER can truncate your data. The SMF dump program, IFASMFDP, creates a data set with a logical record length larger than IEBGENER allows. Thus, IEBGENER will truncate the data set to a logical record length of 32␠760, resulting in a loss of 7 bytes.
What is the IEBGENER utility?
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 IEBGENER in JCL?
JCL – IEBGENER Utility The IEBGENER utility is a copy program. One of its many uses is to copy a sequential data set, a member of a partitioned data set (PDS) or PDSE. IEBGENER also can filter data, change a data set’s logical record length (LRECL) and block size (BLKSIZE), and generate records.
