VISION:Report maintenance is unlike any other CA product.
The recommended loadlib configuration consists of a base loadlib, preceded by a patch loadlib, preceded by a PCP (custom) loadlib if any.
The patch loadlib is created by copying any modules to be corrected from the base to a new loadlib, then modifying those.
The base is never touched.
Similarly, if there are any customizing patches, a 3rd loadlib would be created in the same manner.
This is documented on page 1-18 of the r16.1 Installation Guide.
The history to this is that a cumulative fix file was delivered to customers and we are happy to provide one as well.
To determine what maintenance is applied, use the QJZARK utility that is provided with the system.
There is a VISION:Report program in the member called QJZARK in the SAMPLIB delivered with the installation.
Hence you can run a job like this to see what you have applied to your system:
//STEP1 EXEC PGM=QUIKJOB
//STEPLIB DD DISP=SHR,DSN=your.visionreport.pcpload
// DD DISP=SHR,DSN=your.visionreport.patchload
// DD DISP=SHR,DSN=your.visionreport.baseload
//SYSIN DD DISP=SHR,DSN=your.visionreport.SAMPLIB(QJZARK)
//SYSOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD DUMMY
