Files which are owned by both CA DADS Plus for CICS and CA ShareOption/5 get error messages at CICS startup:
SV575R: DATASET APCTRL HAS MACRF=AIX, CNV, ICI OR NSR. NOT ALLOWED WITH SHR5.
SV557R: REMOVE DATASET FROM SHR5 AUTHORIZATION LIST OR CHANGE THE MACRF SPECIFICATIONS.
The purpose of using the //DADSIN DD in the CICS startup JCL, is to tell CA-Dads Plus for CICS not to allocate the files at CICS startup time and allow the files to be successfully controlled by CA ShareOption/5. By using the //DADSIN methodology you can still use CA-Dads Plus for CICS for these files after CICS initializes.
Add the files to the // DADSIN DD dataset which is an override for CA DADS Plus for CICS.
The DADSIN can take the form of a sequential file, a PDS or be inline to the CICS startup JCL.
//DADSIN DD DSN=inputfile,DISP=SHR sequential file
//DADSIN DD DSN=inputfile,DISP=SHR member of PDS file
//DADSIN DD * inline JCL
Each record is RECFM=FB,LRECL=80
The format of each record is:
