1. Mainframe Connectivity
ViaSQL
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
Viaserv, Inc.

3. TCP/IP Requirements VSE ViaSQL Direct ODBC platform
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
ViaSQL Integrator (Gateway) platform
Windows NT/2000
Viaserv, Inc.

4. ViaSQL Access Server TCP/IP Configuration
T C P / I P P A R A M E T E R S
Listener Transaction ID MDIL
Dedicated Terminal ID TCP*
Initialization String
--- Port Assignments -
Listening Service
Port # Transid
MDI
MDI2
00000
(and more -- up to 30 ports)
Viaserv, Inc.

5. 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
Viaserv, Inc.

6. ViaSQL Listener Transaction
Typically started and stopped with ViaSQL Access Server start/stop transactions
Must be running for TCP/IP connectivity
Viaserv, Inc.

7. Dedicated Terminal ID CICS terminals dedicated to ViaSQL
must be sequential
defined in TCT table
limits the number of concurrent connections
Viaserv, Inc.

8. 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
Viaserv, Inc.

9. 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

10. TCP/IP Resources ViaSQL TCP/IP Guidelines Should be able to ping
with TCP/IP Configuration Table
Should be able to ping
Viaserv, Inc.

11. APPC Requirements VSE Windows 95/98/NT/2000
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.
Viaserv, Inc.

12. APPC Resources ViaSQL APPC Guidelines APPCTEST
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
