RE: Are data queues reliable? -- MIDRANGE-L

× The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

We have used DTAQs here for many years (long before I started with this
company). We have PC applications that create data which is downloaded to
an SQL server. An application then downloads the data into a DTAQ on our
iSeries. Depending on the type of data (and I have no idea what the data
looks like on the SQL server) the data is loaded into one of a many DTAQs on
the system. We have continuously running jobs (one per DTAQ) that monitor
for transactions. We also have a job running that monitors all of the
monitor jobs and restarts non-running monitor jobs.
As each monitor job finds data in the DTAQ the programs writes the raw data
to a log file before doing any other processing to it. The program than
continues to slice and dice the downloaded data and place it into the
appropriate files.

We have a homegrown program that we use to look at the data in the ques by
using the APIs that are available, but there is JCRDQE (JCRCMDS.com) that
you can utilize also.
