Allocating data sets to your TSO session

A table that shows the data sets that you must allocate to the TSO session to run the CICS® VR ISPF dialog interface.

Table 1. ISPF dialog data sets
ddname CICS VR Created by
DWWCON1 CICS VR recovery control data set See Note 5.
DWWCON2 CICS VR recovery control data set See Note 5.
DWWCON3 CICS VR recovery control data set See Note 5.
DWWMSG CICS VR message data set See Note 1.
DWWPRINT CICS VR report data set See Note 2.
DWWLLIB Load Library See Note 4.
DWWSLIB JCL skeleton library See Note 4.
ISPFILE File tailoring output and your JCL skeleton Your existing ISPF data set. See note 3.
ISPLLIB Load library  
ISPMLIB Message library  
ISPPLIB Panel library  
ISPPROF User-session defaults, read/write tables Your existing ISPPROF data set.
ISPSLIB JCL skeleton library See Note 3.
ISPTLIB Read tables (default)  
DWWDUMP CICS VR diagnostics data set See Note 6
DWWDMSG CICS VR prolog and epilog data set See Note 6
Note:
  1. DWWMSG defines the output data set that contains the CICS VR messages. Use a different data set name than the one used on this system by the CICS VR server address space.

    The DCB parameters for this data set are RECFM=FBA and LRECL=133. The block size can be provided on the DWWMSG DD statement and must be a multiple of 133. The default is 27930.

  2. DWWPRINT defines the report data set that contains the reports produced by CICS VR. Use a different data set name than the one used on this system by the CICS VR server address space.
  3. Ensure that the library containing your own CICS VR JCL skeletons is allocated to both the ISPSLIB and ISPFILE DD statements.
  4. Since CICS VR uses LMFIND to locate a member in ISPLLIB and ISPSLIB, only four data sets can be concatenated in these libraries. Since this might be a problem for some users, CICS VR supports alternate names: DWWLLIB for ISPLLIB and DWWSLIB for ISPSLIB. CICS VR uses DWWLLIB in place of ISPLLIB and DWWSLIB in place of ISPSLIB.
  5. Do not use the RCDSs created by the Installation Verification Procedure (IVP). Instead, check that the clean up job, DWWCLNUP, has run to delete the IVP data sets. Review either Understanding the recovery control data sets (RCDSs) if using the CICS VR server address space, or Creating and maintaining the RCDS when not using the CICS VR server address space when not using the CICS VR server address space.
  6. DWWDMSG and DWWDUMP define the output data sets to which CICS VR writes diagnostics and abend information. If these data sets are not allocated, this information is unavailable.
