Issue/Introduction

The hooks are now provided in new compressed format and when customers download the PTF from Broadcom support portal, they usually see below format of data:

++SAMP(Z232194E) DISTLIB(ACUWJCL ) SYSLIB(CCUWJCL )  .                         
$$ GIMDTS  FORMAT                                                              
$$.FB    &  "}  ..

How to have data correctly uncompressed and in readable format. 

Environment

Release :  All

Component : CA Disk Backup and Restore

Resolution

Looking at the 1st MCS statement after the ++SAMP into the source got in mainframe, there is the following statement:

...

$$.GIMDTS  FORMAT   
$$.FB ...&.."}...0  

...

GIMDTS is a separate SMP/E service routine (residing in SYS1.MIGLIB), that will uncompress the PTF content when the RECEIVE/APPLY will be executed.

Below the IBM details on this argument :

So, simply doing RECEIVE/APPLY of the PTF, the source data will be uncompressed and copied in the CCUWJCL library in the correct original format.
