Hi Rameshkumar.h.k,
Honestly, i don't understand.... when u say :
1)You should pass CHECKpoint frequency value from JCL to
cobol program. what's it....give me an example please in
cobol program, and in JCL....

Answer / vicky

Since I cannot type in all details...just letting u know some of them----
we need to make some changes to the JCL and also the cobol pgm.
In JCL-
Firstly, we need to include a library for smart restart.
Secondly, define a DSN for the chkpoint restart file, that shall store the information about the chkpoint created and with the number of records committed till the abend occurred ,so that when Job is restarted chkpoint can be checked.
Thirdly,the SYSIN for the RAINPUT step will consist of all the other parameter.Eg- frequency, chkpoint, sql code, etc

JCL will look like-
//EXAMPLE JOB
//STEP1 EXEC PGM=EXAMPLE
//define libaries
//OUTFILE DD DSN=file PS ,DISP=OLD
//
//RAINPUT DD * <-- Optional Smart/RESTART parameter file

CKPT_PACE(50)
//

Coming to the cobol pgm-

we need to code a switch whose value can be chked in case of abend, based on negative SQLCODE returned.
the value returned can be
0 = (Intial start)
1, +2001 = (Restart)
Later Commit para can be called.
If value 1 and +2001 , the pgm can be restarted for a same sqlcode returned , that number of times defined in
parameter of RAINPUT

Hope u could be somewht clear to this,,,

You should pass CHECKpoint frequency value from JCL to
cobol program.Intern cobol program will have the table of
retart logic.
Table contents(coloumns)be: 1.No of records ,2.No of
records + 1, 3.no of records processed etc.
Once the updattion or insertion got stucked while
processing ,All the relative data will be stored the above
mentioned table.

So check the record from table .Fix the abend and restart
your job for the failed step.

This is mainly production support work .manually u have to
check the record .and get the records info from the table
and restart the job from the failed step

Hope You clread

Answer / vicky

CHECKpoint frequency value from JCL to
cobol program. This means, number of records after which the data should be commited, and chkpoint fixed.
If chkpoint frequency is 10 , then after every 10 records, data will be committed.

SET is the ANSI standard for variable assignment, SELECT is not. SET can only assign one variable at a time, SELECT can make multiple assignments at once. If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one) When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value) As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.
