You will learn how to copy data to a Unix file using JCL
Many techniques are available to copy data between z/OS data sets and Unix file names.
The challenge uses JCL to execute Unix shell commands and execute a standard z/OS system utility to copy data from a partitioned data set member name to a Unix file name.
Information About Copying Data between Unix Files and z/OS Data Sets
Common ways to copy data between Unix file names and z/OS data sets:
- Using JCL to execute standard utilities
- Using Unix shell cp command
- Using TSO ocopy, oput, oget, oputx, and ogetx commands
- Using ISPF panels
- Using ISPF editor
Modify and submit JCL to copy a PDS member name to a Unix file name
- Reminder - substitute your ID for Z##### and z#####
- Copy input is data set name Z#####.PDS.DATA member name MIX
- Copy output is Unix path and file name /z/z#####/mix
- Program IEBGENER DDNAME SYSUT1 is input
- Program IEBGENER DDNAME SYSUT2 is output
- JCL DD PATH= is used to reference Unix file name
- What follows PATH= must be enclosed in single quote marks
A comma is needed after the path name to continue the DD statement
- The Unix file path and file name is lowercase
- Program BPXBATCH DDNAME STDOUT is the Unix command output
- JCL RESULT stepname, DDNAME STDOUT, needs to write output to &SYSUID..P2.OUTPUT(#12)
- Edit Z#####.JCL member name CH12JCL
Modify JCL to copy data to a Unix file name, then execute Unix word count command,
' wc ' proving data was successfully copied
- Change line 000013 where SYSUT2 is output of the data copy
- Change line 000017 where STDOUT is output of the word count command
proving data was successfully copied into Unix file name
- Submit modified JCL to copy data and verify successful copy
- Check output for successful copy
NOTE: The first time running CH12JCL, the DELETE step finish with a return code of 256 as a result of attempting to remove filename mix when mix filename does not exist. Return code 256 is the expected return code. All is ok.
Successful completion includes member name #12 in P2.OUTPUT with word count output
