Native SQL, Agent-less access to Oracle, MS-SQL, MySQL, Excel & other data sources
DB-Gate: IBM i Remote Database Access
• DB-Gate strengthens the connectability of the IBM i in a multi-platform environment
• DB-Gate strengthens the IBM i which can now easily become the repository of data which has been stored in Oracle, MySQL, etc.
The Vision
DB-Gate
The Challenge: To integrate data in a multi-DB environment
• Companies have heterogeneous environments need to integrate data from the financial application on System A, the ERP application on B and the CRM on System C.
• ODBC is good BUT the initiative for executing ODBC lies within Windows or Linux the software must be written Visual Basic, .NET, C#, etc.
• So who has lost out?– Everyone connected with the i, from CIO to programmers.– The company which does not fully utilize the resources which it has-
those programmers who know RPG and Cobol– The IBM i (and IBM itself!) whose importance and centrality in the
organization have deteriorated
Customer Testimonial- Wolseley LLC, Canada• Company (http://www.wolseley.com) is the world’s largest trade
distributor of plumbing and heating products and a leading supplier of building materials.
• Group revenue in 2012 was 13 billion GBP.
• They use Oracle Access Manager to synchronize data between Oracle DBs and IBM i, “pushing” and “pulling” large amounts of data in both directions. However, OAM does not run on 7.1; DB-Gate does!
• “I ran a procedure which extracts all of the items from one of our divisions and sends it using DB-GATE connect (as Insert) from 5-6 files. The records sent were almost one million and I calculated that it will run for almost 10-12 hours, which is OK.”

I had several small issues with DB-Gate which I worked with the vendor supplying them with all traces.
I am happy with overall tests with DB-Gate to Oracle and now MSSQL server also with all RPG SQL embedded programs and will soon be moving to DB-Gate from Access Manager from Oracle since they (Oracle) have stopped support in 7.1 OS.

• Use a Type-4 MS JDBC driver and Java to access SQL• Concerns: Non-standard, knowledge, language,
performance, maintenance issues
• IBM InfoSphere Federation on Linux/Windows• Concerns: Additional hardware, cost (>$70K), complex
• DB-Gate• Advantages: Native and standard IBM i, superior
performance
Accessing Other DBs from IBM i

When an i application requires integration of data with any other database…

You have the freedom of choice to run it on any platform except the i.
This is because the i cannot “connect” to other databases, but they all can ODBC to the i !

Oh yes - you can use a complex customized solution based on FTP, use a product that requires a
middleware server, or write complex non standard APIs, …but why? Now you have an alternative…
DB-Gate (patent-pending):requires no API, no HW/SW server, and it runs native
on the i, including STRSQL, and CRTSQLxxx, and even integrates with Host Server Authentication

• However, DB-Gate can work in “Server Mode” as either an Internal or External server (both are optional)
– Internal Server: A server subsystem needs to be started
– External Server: Removes load off of the IBM I; installed and started from a PC
No Hardware/Software server is required…

• “Keep alive” statement that is sent repeatedly so that the server does not disconnect
• Support for SMB (MS protocol) to allow access to Excel/CSV files on shared folders
• Added support for reading Excel 2007-2010 (XLSX) formats • Can run as an internal server on the i, eliminating the JVM starting time • Can run as an external server on a PC, meaning there is no JVM on the i,
reducing an extensive load from the i. • Running on a PC enables DB-Gate to work with additional data sources by
employing the JDBC-ODBC bridge. This means for example that we can get data from MS Access.
• Federated databases – support planned
