What is condition parameter?
Condition parameter is used to decide execution of the JOB step based on the return code. And also COND parameter used to specify the return code validation the system uses to determine whether a job step will continue processing or not. COND parameter can be coded at JOB level and Step level.
How can we skip a step using cond in 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….Let us take some examples-
| Types | Condition example | Explanation |
|---|---|---|
| Type 1 | COND=(0,EQ) | Is return code 0 equals the return code from the previous step? If this condition is true then bypass this step. |
What would happen if cond parameter is present on both job and EXEC statement?
The COND parameter on both the JOB and EXEC statements is useful to set some conditions for all steps in the job and other conditions for particular steps. No COND parameters on JOB or EXEC statements means the system does not perform any return code tests, but tries to execute each step in the job.
What is the difference between cond even and only?
– COND=EVEN is to tell the SYSTEM that to execute that step even though any of the previous steps abnormally terminated. The difference Between EVEN and ONLY is, Even executes irrespective of the previous steps return codes. That steps gets executed in case of normal return codes and also in case of abends.
How do you Cond a parameter in JCL?
A COND parameter can be coded in the JOB or EXEC statement of JCL. It is a test on the return code of the preceding job steps. If the test is evaluated to be true, the current job step execution is bypassed. Bypassing is just omission of the job step and not an abnormal termination.
What is instream procedure in JCL?
When the procedure is coded within the same JCL member, it is called an Instream Procedure. It should start with a PROC statement and end with a PEND statement. The varying input to the JCL such as file names, datacards, PARM values, etc., are passed as symbolic parameters to procedures.
What is RLSE in JCL?
RLSE function notifies the close function to release unused space on the dataset closes. RLSE function supports sequential, partitioned and VSAM. If RLSE function specified and an abnormal termination occurs, the system does not release unused space even though the data set is open.
Why do we use parm in JCL?
The PARM parameter is used to pass the input data from job step to program. If JCL needs to pass more than one sub parameter, those should be separated by comma (,) which are enclosed in parentheses/quotes. PARM parameter can pass maximum 100 characters.
Can I override a PGM parameter?
You can override any parameter in a cataloged procedure except the PGM= parameter in the EXEC statement. Overriding of statements or fields is effective only for the duration of the job step in which the statements appear. The statements, as stored in the procedure library of the system, remain unchanged.
What is the use of Cond 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. 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 the use of the concond parameter?
COND parameter is used to test return codes from previous job steps and determine whether to bypass or execute specified job step. Return code is set based on the status of execution of a job.
What is the use of time parameter in JCL?
TIME – The time parameter is used to specify the amount of CPU time that a job or job step is permitted to utilize. Syntax -> TIME=minutes OR TIME= ( [minutes] [,seconds]) minutes can be between 1 and 1439 seconds can be between 1 and 59 Example JCL -> If coded on JOB //MYJOB JOB (E234),’RAMESH KRISHNA’,TIME= (20,30)…
What is the step level of the COND parameter?
STEP level – In EXEC statement. In most cases, it is a good practice to code the COND parameter at STEP Level but based on your requirement, you can code this at JOB level or STEP level or at both the places. Here, RC is Return code and OP is Operator and STEPNAME is the name of the step.
