• iSeries
– DB2 UDB, CLP, RPG, Business know-how, ERP...
• Domino
– Notes Script, Java, Formula Language
• WebSphere
– Java, Java, Java...
• Microsoft Visual Studio
– VB, C++, VB.NET, C#, XML, ADO, SQL Server...
• Apache, IIS, PHP, ASP...
5
Platform Integration...
• Use your existing skills wherever possible
– Business know-how
– Technical skills
• Communicate through open standards
– TCP/IP protocol
– Consider using XML
– No need for mastering all technologies / platforms
• Deploy code on the most suited platform
– But make its functionality network enabled !
6
Platform Integration...
• Sockets based system integration is very fast
– Back to basics, no thick layers, no middleware...
• Very promising
– TCP/IP is available on all platforms
– Add a new perspective to possible system integration
• Use proven technology
– Usage of TCP/IP is common practice (and stable)
– Technologies wide spread
– Very limited learning curve
7
Sockets4U2 on iSeries
• Synchronise and replicate databases
– DB2 UDB for iSeries, SQL Server, MSDE, Access, MySQL…
• Synchronous execution of program logic spread amongst
different systems and platforms
– RPG requests and waits for data from Visual Basic code
– Visual Basic requests and waits for data from RPG code
• Dynamic Web Site
– On-the-fly retrieval of iSeries data
– On-the-fly processing
• Embrace new technology
– HTTP, XML, SOAP…
...with response times up to 10 milliseconds...

Sockets4U2 on iSeries
• Implementation of a TCP client
TCPCLIENT/TCPCLIENT RMTIP('10.110.49.102')
RMTPORT(6000)MSG('SRONAM^FMI') WAIT(Y)
CCSID(00500)EOT('CR/LF') TIMEOUT(5) VERBOSE(N)
LOG(Y)
Synchronous execution
• Outbound data:
– command line parameter
– dataqueue
• Inbound data:
– dataqueue
• Feedback to calling program
– completion or failure code through *LDA
We make sockets client functionality available...

Synchronous execution
• Inbound data:
– Dataqueue
• Processing:
– Exit program in RPG or CLP (only a few lines of code)
• Outbound data:
– Dataqueue
• Optimised for iSeries:
– NLS, multiple-access, spawn, pre-start jobs, pre-open files, cache…
