Re: limit users max active jobs

should have been more specific...

not so much wrong with odbc/jdbc connections... but off platform queries
against the DB2 tables is a problem that most large companies definitely
take note of and have began restricting...
(stored procedures ok - a webservice that returns a true data object (like
JSON or XML) instead of a columned result set is even better)...


Here are some advantages I can think of for using a http endpoint that
calls an i sqlrpgle that accepts and returns a JSON/XML object...



1. queries/DB access are kept on iSeries along with database DDL and
program source code – if ever there is a change in table structures, the
dependent programs will easily be identified (via cross reference tools -
ie. hawkeye, x-analysis, etc.)
2. Reduces required talent needs – the data can be pulled and packaged
to a json output (from an i developer) and delivered straight to a front
end ui/ux developer.
3. The sql queries within the sqlrpgle programs will be very efficiently
written by i developers who know the database the best.
4. if the http endpoint is developed a certain way it falls into the
flow of how most i shops roll out new programming in change management
systems (such as turnover). A few years back when I was at a certain very
profitable Berkshire Hathaway company, with 100+ iSeries developers and
many .net’rs, they implemented true soap and rest webservices (with pcml)
and this was an absolute nightmare pushing it up through the change
management system. At my next gig, their very clever solutions architect
devised the model I speak of and it worked beautifully within the iSeries
shop and change management system.
5. i developers will be working with newer more modern methods that are
more exciting and interesting.
6. Can very easily be leveraged into a MVC framework.

We use ODBC for thousands and thousands of web transactions. We do not
expose the database to ODBC - the underlying tables are secured against
public access. We expose information via stored procedures which adopt
appropriate authority.

With respect to the subject of the thread, if we find a performance
issue, we can work on that one program until we meet expectations. We
don't have a full suite of tests for every stored proc, but we're
working on it. Once we get there, we will be able to automatically
stress test the system after making changes.
