Manually Deleting Checkpoint Files
Instead of using twbrmcp, you can delete the files manually. The procedure for manually deleting files varies depending on the operating system.
On UNIX or Windows Systems
rm <user-defined directory>/*
del <user-defined directory>\*.*
On z/OS, you can remove checkpoint files with either of the following two methods:
1 Go to the Data Set Utility panel (panel 3.2) in the Primary Options Menu of the TSO System Productivity Facility.
2 Enter the name of each checkpoint file in the name entry fields provided on this panel.
3 Type D (for “delete”) for the requested dataset option.
4 Hit Enter
Add a step to the beginning of your next Teradata PT job, with the following Job Control Language statements:
//CPD1 DD DISP=(OLD,DELETE),DSNAME=<high-level qualifier>.CPD1
//CPD2 DD DISP=(OLD,DELETE),DSNAME=<high-level qualifier>.CPD2
//LVCP DD DISP=(OLD,DELETE),DSNAME=<high-level qualifier>.LVCP
where <high-level qualifier> is the high-level qualifier you supplied to the TBUILD JCL PROC when you submitted the job that created these checkpoint files. Or substitute the names of your checkpoint datasets for everything to the right of DSNAME= above, if you have a different convention for naming them.
For examples of naming and using checkpoint datasets on z/OS “JCL Examples,” see the Teradata Parallel Transporter Reference.
