Ingres Environment at the University of Melbourne

   At Melbourne University, we had been using Ingres since the late 1980s for major systems such as Finance, HR and Student Administration (since moved to Oracle in the 2000s). There have been a large number of patches for our current version of Ingres, so keeping up-to-date is important! We had previously been using Ingres 6.4/05-06 for a number of years. An upgrade to Ingres II was completed in 2001 and then a subsequent upgrade to Ingres 2.6 on Solaris in 2005.

   Our development teams program in 4GL and Embedded SQLC. Personally, I have been using Ingres since 1991 as both a developer and a DBA. I was also a long-term consultant at other University affiliates such as the Australian Music Examination Board (Vic).

   User access to our Ingres systems consist of SSH terminal connections using Teraterm, WinQVT (both PC clients) or MacSSH, NiftyTelnet (Mac equivalents). Ingres keymappings can be tricky to configure due to the escape sequences involved.

   In recent times, we have opened up access to our Ingres databases via ODBC for the Unicard Student Cards system and via JDBC for the Oracle Portal using Toplink. This requires OS-authentication to be setup with Ingres as part of its C2 security compliance.

   Some of our clients use BI/Query from Hummingbird for generating adhoc SQL queries and reports with Ingres (BI/Query used to be called GQL when it was owned by Andyne). For the security conscious (i.e. not ODBC), I have successfully run BI/Query and GQL over an SSH tunnel connection. In recent times, using RazorSQL via JDBC is an easy way to connect to the database.

  Update: Melbourne University has replaced the administration systems for Finance, HR and Research) with Oracle Apps at a project cost of 42+ million AUS. In comparison, the current Ingres systems they replace were developed in-house at an estimated development cost of just 4 million (AUS) during a 10-15 year lifetime.

  Update #2: A new .NET/Oracle implementation of the Student System (StudentOne) from TechnologyOne has been evaluated and is due to be implemented at the University of Melbourne by May 2008 with a project budget of 23.1 million dollars! The recurrent costs are 4.477 million dollars and a half-yearly maintenance fee of $553,000 dollars! Source: MU Council Minutes, November 2006, Section 14.2

  Update #3: The existing Merlin system is in its fourteenth year of reliable service and has been upgraded to new Sun V890 hardware in conjunction with Solaris 10 zones. Most of our current processes are running two to three times quicker than previously, eg Admin_Stats processing has gone from two hours & 30 minutes to just 32 minutes! The database setup is Ingres 2.6/0305 with JDBC/ODBC enabled. We have worked through a number of bugs and are now running patch 12843 on our DR/test/production environments.

  Update #4: The Technology One implementation for a new Student System has been delayed by three months until at least September 2008 due to prototypes lacking required functionality and not being delivered according to schedule.

  Update #5: The Technology One implementation has been delayed again until at least 2009! If Merlin had been enabled with some front-end GUI web forms, this may have saved the Uni 20 million dollars in the short term ;)

  Update #6: The Technology One implementation has finally gone live on June 7, 2010.

  Update #7: I have compiled Ingres 9.3 Community Builds 151 & 160 (Opensource) and a test+production version of Merlin for Solaris is running very quickly on the new DBMS server with some stability issues. Now trying 10.1 Community Build 120.

  Update #8: 10.1 build 120 is proving far more stable than 9.3. Have three installations for Prod/Test/DR all working smoothly with no hiccups in four months of operation.

  Update #9: First hiccup on Production: mutex locking problem requiring installation restart. Messy. Will try internal threads (iislaves) via: ingsetenv II_THREAD_TYPE INTERNAL

  Update #10: Internal threads (iislaves) are working fine after 6 months in production. No noticeable performance hit. Happy DBA.
Ingres 10.1 Community Build 125 is now available.
