Millistream Database Application (MDA) version 0.9.39 released

/in /by

The Millistream MDA project team is pleased to announce the release of
version 0.9.39 of our open source application for updating SQL servers
with data from the Millistream Data Feed.

* The maximum value reported in the “instrument-hash-size” in the output of “mda –status”
used the configured value and not the actual value (the configured value is scaled to the
next power of two for performance reasons).

* Rows from corporateactions could not be removed if the message did not contain “source”
(and “source” as a field for this table will be deprecated in the future).

* If the calculated change factor when updating a corporate action with a new adjustment factor
is “1” then the MDA will no longer adjust the prices in the “adjustedpricehistory” table.

* Added error logging for adjustments from a corporate action event.

* On Unix/Linux, write human readable errors to the error log instead of just the errno value.

* Notify systemd on status and main pid of MDA on systemd supported systems.

* Support the systemd watchdog (at the moment only the status and feed received thread are
covered).

* Changed the maximum timeout value for the queue semaphores to 5 minutes from INFINITY

* Updated the AppArmor profile to be compatible with changes introduced in Ubuntu 16.04LTS

As earlier announced, as of v0.9.33 the database schema is developed independently of
the MDA and the latest schema including upgrade scripts is available on our ftp server
under the documents section (MDA_schemas_[version].zip). As of this writing the latest
database schema is v85 and thus the file is available from:
ftp://ftp.millistream.com/documents/MDA_schema_88.zip

Do note however that the latest schemas are only needed if you need the new columns/tables,
they are not mandatory to operate the MDA!

We consider MDA 0.9.39 to be the best version of MDA available and we
recommend that users of older versions upgrade as soon as possible.

MDA 0.9.39 is available for download from the following locations:

Windows installer: ftp://ftp.millistream.com/binaries/windows/
Red Hat / CentOS: https://packages.millistream.com/rpm/
Debian / Ubuntu: https://packages.millistream.com/apt/

Documentation: ftp://ftp.millistream.com/documents/mda.pdf

Windows users upgrade by running the installer for the new version.
