DB2 Server for VM: System Administration

Appendix H. DRDA Considerations

Users who are planning to design applications that:

run on non-VM platforms and use the Distributed Relation Database Architecture (DRDA) protocol to connect to DB2 Server for VSE & VM servers, or
run on VM/ESA and use the Distributed Relation Database Architecture (DRDA) protocol to connect to servers other than DB2 Server for VSE & VM

need to be aware that DB2 Server for VSE & VM's support of SQL does not exactly match the IBM SQL standard ⁵ or the SQL Entry Level standard. ⁶ This appendix attempts to provide some guidance in discrepancies to these standards.

Footnotes:

⁵: IBM SQL is a superset of the SQL99 Entry Level standard
⁶: Entry Level of the International Organization for Standardization (ISO) 9075-1992 Database Language SQL specification
