Dear Team

Can you please help me understand the JCL options to be used for decompressing an unload file on Mainframes.

Followed the below steps, to generate a decompressed unload on windows What would be the corresponding options to generate the very same file from Mainframes.

1. Logged in to Adabas Manager 8.3 (Window Version)
2. Excuted the Unload Utility ADAULD (Giving the Filenumber as Input).
3. Executed Decompression utility ADADCU with the following options. (I needed a Variable Length Mainframe File with, Count of MU/PE fields in 2 bytes) along with FDT.)

DCUFDT, MUPE\_C\_L =2, RECORD\_STRUCTURE = RDW, TARGET\_ARCHITECTURE = (EBCDIC, IBM\_370\_FLOATING, HIGH\_ORDER\_BYTE\_FIRST)

Thanks,  
Sindhu Jose

1. Execute the unload utility. You can unload from a database or a backup.

```auto
ADAULD UNLOAD FILE=###
```

1. Execute the decompress utility, providing the unload dataset.

```auto
ADACMP DECOMPRESS
```

If unloading from a database, you can combine the two steps by performing an implicit unload. You specify the file number in the decompress parameters.

```auto
ADACMP DECOMPRESS INFILE=##
```

Two-byte MU/PE counts will be unloaded if you specified MUPECOUNT and MUPEX parameters in the COMPRESS utility used to create the file that was loaded into the database. If necessary you can run the Database Services utility (ADADBS) to modify the file’s setting prior to the unload.

```auto
ADADBS MUPEX FILE=### MUPECOUNT=2
```

Obviously you will need the appropriate JCL to perform these utilities.
