CONNX for CICS/VSAM for OS/390 / z/OS and VSE is a CICS C++ application built with the SAS/C 7.00 Cross-Compiler for Windows, a product of the SAS Institute. CONNX for CICS/VSAM can only access VSAM files defined to and managed by the target CICS region or partition. The CONNX Data Dictionary Manager metadata import utility requires that the COBOL copybooks for the target CICS VSAM files reside in OS/390 / z/OS partitioned data sets or in VSE libraries defined with FTP read access.  

CONNX for VSAM / QSAM / PDS for OS/390 / z/OS is a C++ application built with the SAS/C 7.00 Cross-Compiler for Windows. CONNX for VSAM / QSAM / PDS can access any VSAM or QSAM (partitioned- or physical sequential-) data set defined on the target system. COBOL copybooks that map the target VSAM or QSAM files must reside in a partitioned data set defined with FTP read access. VSAM files which are allocated exclusively to CICS regions can be accessed only when the regions are quiesced. For read-only queries, CONNX for VSAM / QSAM / PDS can access VSAM files defined with VSAM read share options of 3 or 4 when the files are allocated to one or more CICS regions. For update processing, the target VSAM data sets must be allocated exclusively to a CONNX for VSAM / QSAM / PDS started task or batch job.
