User was running FDRABR DUMP TYPE=SCR and specified IFNOTCAT so it will remove all my uncatalogued entries from the specific volumes, however some VSAM Components are not getting selected. How can the user delete those uncatalogued VSAM Components?

FDRABR Superscratch can be used to delete uncatalogued entries by specifying the IFNOTCAT keyword. However, for security purposes, some types of datasets are excluded from selection, they are described in the FDRABR Manual as below:
 

Exceptions to automatic archiving

The following data sets are never selected for Archive or Superscratch:

• For Archive, data sets in the ARCHIVE PROTECT LIST, if the protect list is enabled in the FDR Global Options (ARCPROT / PROTECT). For Superscratch, data sets in the Scratch Protect List if enabled (SCRPROT / SCREXCL).
• Data sets marked “do not archive”, that is, data sets for which OPTIONS=AD, ND, or EX have been set with program FDRABRM.
• Data sets on volumes whose ABR Model DSCB indicates “Disabled for Archive” for TYPE=ARC or “Disabled for Superscratch” for TYPE=SCR. These flags are set by program FDRABRM or the ABR TSO/ISPF panels.
• Data sets that begin with the ABR prefix (normally “FDRABR” unless overridden in the FDR Global Options). However, if SELECT ABRBKUP is specified then ABR will select ABR backup data sets that are expired.

The following data sets will not be selected by General Archive Selection Criteria on the DUMP statement or by a SELECT ALLDSN statement, but can be selected by other SELECT statements with more specific DSN= operands, including DSN=**:

• Data sets prefixed by SYS1.
• OS PASSWORD data set
• SYSCTLG data set
• Temporary data sets. If you want to select temporary data sets, specify SELECT TEMP preceding any SELECT ALLDSN or any other SELECT that would select the same data sets. DSNENQ=USE and CRDAYS=1 are recommended to be sure that temporary data sets in use will not be selected.
• Data sets found to be in-use when using the data set enqueue option (DSNENQ=), unless ENQERR=PROCESS is specified.
• Data sets with a last reference date of zero (00000) if data set selected by ADAYS= or ADATE=.
• Model DSCBs (data sets with no extents).

Even though it is not documented, uncatalogued VSAM Components are also excluded from Superscratch selection.

In order to remove those VSAM entries without a CLUSTER defined, you can run the following job instead:
 

//STEP1   EXEC  PGM=FDREPORT
//SYSPRINT DD  SYSOUT=*
//SYSPUNCH DD SYSOUT=*
//* SYSPUNCH DD SYSOUT=(A,INTRDR)
//SYSUDUMP DD  SYSOUT=*
//ABRMAP   DD  SYSOUT=*
//SYSOUT   DD  SYSOUT=*
//SYSIN    DD  *
  DEFAULT DISABLE=DUPDSNCHECK
  XEX XDSN=(FDRABR.**,SYS1.**)
  XSELECT  STORGRP=(STORGRP1,STORGRP2,...),
  CATALOG=NO,DSORG=AM
  PUNCH FDRLIB=MASKDD
  SORT  FIELDS=VOL,BREAK=RPM
  PRINT  RPTYPE=SELPCH
//MASKDD   DD  DATA,DLM=$$
)REPRO
//DELETE JOB (ACCT),CLASS=M,MSGCLASS=X,NOTIFY=&SYSUID
)PREFIX
//DEL<$$CCL5> EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//DISK     DD DISP=SHR,VOL=SER=<VOL>,UNIT=3390   
//SYSIN    DD *
)ENDPREFIX
   DELETE <DSN> VVR FILE(DISK)
)SUFFIX
/*
$$

The job will check all the storage groups selected and identify the VSAM datasets with CATALOG=NO attribute. Then it will sort the entries by volume and create the delete job and put it on the SYSPUNCH DD statement.

When you are comfortable with the results shown in the SYSPUNCH DD statement, you can either:

• Submit the job created in the SYSPUNCH DD or
• Update the SYSPUNCH DD statement with the commented line (SYSPUNCH DD SYSOUT=(A,INTRDR) and run the job again. That will automatically run the created job and delete the datasets found.

DO NOT SUBMIT THE JOB GENERATED IN SYSPUNCH DD WITHOUT CHECKING THE SELECTED ENTRIES AND ENSURING THEY INDEED QUALIFY FOR DELETION.
