| Which is better to use DSNTIAUL or IKJFT01 for unload in terms of performance and flexibility?? |

| There is no program called IKJFT01 to unload but you would need to use IKJEFT01 to execute DSNTIAUL |

Neither; unless you are trying to do something really outré, you are better off using a utility such as, e.g. BMC Unload+. |

IKJEFT01 is the TSO/E program. It is also called as TMP, Terminal Monitor Program. You use it whenever you wish to perform a TSO function within a batch job. It allows you to perform any TSO function. IKJEFT01 allows you to run programs written in CLIST and/or TSO/E REXX. You can also invoke other environments, such as ISPF , allowing you to run ISPF Dialogs in a batch environment. It also allows invoking DB2 commands. (After all DB2 is just another sub-system under zOS.)
On the other hand and from the manuals, DSNTIAUL, is a sample unload program for DB2. This program, which is written in assembler language, is a simple alternative to the UNLOAD utility. It unloads some or all rows from up to 100 DB2 tables. With DSNTIAUL, you can unload data of any DB2 built-in data type or distinct type.
Now with that said - your comparison does not stand on any practical grounds. What is that you might get after comparison?
Possibly a better comparison could have been among DSNTIAUL, DSNTIAD, DSNTEP2 and/or DSNTEP4 -- but I leave it to you. Curiosity kills...  . |

@Anuj: Thanks for the details. Exactly I would look up more and come up with the actual stats.
Thank you other as well. |

How does your organization define "better"?
To get more suggestions, you need to specify what you are specifically going to consider. Each tool has good uses. Which one to use depends on the requirement.
Are these unloads to be used to load another database somewhere or are these intended to be backups? |

What I would do is code both (several) methods and test with the same data.
Make sure to do a large enough amount to show any differences.
Run your tests and compile 'actual statistics' for your system. |

You're welcome and good luck!
Suggest you look for the points, Dick & Dave has mentioned, when you proceed further. |
