ViaSQL

Mainframe Connectivity

Viaserv, Inc. Mainframe Connectivity – 2

Access to ViaSQL Access Server

ViaSQL Direct and ViaSQL Integrator TCP/IP

– easier to set up– less configurable

APPC (LU6.2 or SNA)– can be complicated– more performance potential

One ViaSQL Access Server transaction can accept both connection types

TCP/IP Requirements

VSE – Connectivity Systems Inc. TCP/IP stack

ViaSQL Direct ODBC platform– Windows 95/98/NT/2000– native TCP/IP stack

ViaSQL Direct JDBC platform– any JAVA platform– native TCP/IP stack

ViaSQL Integrator (Gateway) platform– Windows NT/2000– native TCP/IP stack

ViaSQL Listener Transaction

Installed automatically with ViaSQL Access Server (if TCP/IP was specified)

Long-running CICS transaction Listens on assigned ports, initiates CICS service transaction,

passes connection on, returns to listening

ViaSQL Listener Transaction

Typically started and stopped with ViaSQL Access Server start/stop transactions

Must be running for TCP/IP connectivity

Viaserv, Inc. Mainframe Connectivity – 7

Dedicated Terminal ID

CICS terminals dedicated to ViaSQL– must be sequential– defined in TCT table– limits the number of concurrent connections

Other TCP/IP Parameters

Initialization string– Relates listener to tcp/ip partition. Default is 00

Listener port #– port numbers assigned to ViaSQL listener

Service transid– CICS transaction(s) assigned to ViaSQL Access Server

TCP/IP Setup — Other End

Standard Windows 95/98/NT/2000 setup– specify IP address of VSE platform– specify port number assigned to desired ViaSQL Access Server

transaction Same for:

– ViaSQL Direct ODBC Driver– ViaSQL Direct JDBC Driver– ViaSQL Gateway

TCP/IP Resources

ViaSQL TCP/IP Guidelines– with TCP/IP Configuration Table

Should be able to ping

APPC Requirements

VSE– many VTAM and CICS definitions

Windows 95/98/NT/2000– Microsoft SNA Server configured to match VSE setup– MS SNA Server client required on each machine if using ViaSQL Direct

ODBC Driver.

APPC Resources

ViaSQL APPC Guidelines– with APPC Configuration Table

APPCTEST– tests APPC connectivity outside the ViaSQL software

• APPCTEST transaction in CICS• supplied client program run from ViaSQL Gateway or

ViaSQL Direct platform– helps isolate problems
