| Code: |
| exec cice delete file(file name) end-exec, |
should this alone would work for deleting all the records? |

| What does the CICS Application Programming Reference manual tell you about the EXEC CICS DELETE command? |

| Whoa, you may want to think about doing this in Batch with a Batch program or 3rd-Party product. |

Hello,
After closing this file to the online. . .
However - Between the performance issue and the potential for failed/incorrect transactions, suggest you consider what Bill has posted. . . |

You can delete all records in a VSAM file in CICS by reading for update each record and deleting it; however, this is NEVER a good design for a system since you are using CICS in a very wrong way.
Probably the most common and easiest way to do what you want is to close the file to CICS, delete and define it, load an initial record into it, then open the file to CICS again. |

使用CLOSE EMPTY去清空一个online文件
| Code: |
005900 EXEC CICS SET
006000 FILE (SS84WS-COMMAND-FILE-NAME)
006100 CLOSED
006200 ENABLED
006300 EMPTY
006400 NOHANDLE
006500 END-EXEC

To ensure data/program integrity, EVERY program which accesses this file must issue ENQ/DEQ API's, using the same resource-name, when the region is ACTIVE, while attempting to DELETE all the records. Hopefully, there aren't too many programs.
This is why a Batch solution would be the better way to go when the region is DOWN.
Just my .02 cents.... |
