  1. SQL Migration

  2. The Migration Project • When did you begin the migration? • How long did the project take? • When was it completed? • How did you prepare for it (data scanners, custom programming scanner, etc.?)

  3. Contra Costa Community College District • Purchased and installed new hardware in summer 2011 • Configuration and installation of the SQL Clean environment was completed October 2011 • Migration was completed April 2012 (during DUG) • Started running data scanners in summer 2011 • Began converting custom paragraphs into Envison reports fall 2011 • Rewrote Query Builder reports into SQL Reporting Services throughout the migration

  4. Marygrove College • Began project October 2010. • Did not buy servers, ended up renting since there was no budget • New servers installed March 2011 • Plan was to run 3 test migrations with final migration July 4th 2011 break. • Did not need to run DMIG. • Completed July 4th break – 4 days. • Several challenges – printing, third-party products, custom integrations

  5. DMIG • What challenges did you experience with the DMIG process? • How long did DMIG take to run for your environment? • How big (gigs/records) would you estimate your environment to be? • How many times did you run DMIG?

  6. Contra Costa Community College District • DMIG ran 3.5 days • 1 additional day was needed to defrag indexes • The size of our SQL database environment is: • SQL DB: 25 GB • SQL IDX: 135 GB • SQL LOG: 36 GB • We ran 9 tests of DMIG before the final migration to production

  7. Contra Costa Community College District • The size of our environment pushed ALL of the limits of DMIG! • We ran into MANY errors and DMIG constantly timed out • Datatel programmers and team leads were involved with every execution • Improvements were made to DMIG throughout the project

  8. Contra Costa Community College District • DMIG weird error example: Error encountered during Bulk Insert into PERSON table during processing of PERSON file. Fatal: 2627(14): Violation of PRIMARY KEY constraint 'PK_PERSON'. Cannot insert duplicate key in object 'dbo.PERSON'

  9. SQL Impact • Did the migration result in improved overall performance of Colleague, reduced performance or no noticeable change? • Has there been any noticeable impact or improvement to specific Colleague processes as a result of the migration?

  10. Contra Costa Community College District • Overall we have experienced improved performance • It’s not the great WOW we’ve had with other hardware replacements • We’re still tuning and adjusting parameters • Some processes are faster, some are slower • Depends a great deal on computed columns

  11. Marygrove College • Experienced improved performance • Overall performance better more stable • Migrating existing SQL jobs was challenging with a new domain • We’re still running some scheduled process on SQL 2005 as well as Report Manager • End user’s running jobs against SQL affects performance considerably • Looking to replicating to separate Enterprise SQL server for Report Manager and end user’s SQL access

  12. SQL Reporting • What was your approach to reporting from the Unidata environment? • What solution did you implement for SQL reporting? • How has the transition to SQL reporting been for your I.T. Department and end-users?

  13. Contra Costa Community College District • All of our prior to the migration reports were Query Builder, except a few custom Envision reports • We took advantage of our Microsoft Campus License Agreement and implemented SQL Reporting Services • At no cost • A lot of work for the I.T. Department, Users are VERY Happy • Now implementing SQL Report Builder for ad-hoc reporting • See Fred Tahan’s session at DUG!

  14. Marygrove College • Use SQL Reporting Services • At no cost • Currently in process of establishing project to migrate from SQL 2005 to SQL 2008 • All report development in the I.T. Department • Limited resources to complete • Looking at implementing SQL 2008 differently • Users are frustrated they cannot build their own reports • Also do reports from Envision and Studio • Sometimes it is just easier, better control in logic

  15. Consulting and Services • What consulting services did you purchase from Datatel to assist with the migration? • Did you purchase services from another company? • How much of the migration did you perform yourself?

  16. Contra Costa Community College District Consulting Services from Datatel: • Initial Colleague Installation – clean environment, LPR • Minimal services – some programming • Registration Health Check (after migration) Other Consulting: • Brent Ozar PLF – SQL Server Health Check • iData – QB to SQL Reports • We did all of the migration ourselves, with a LOT of help from Solution Center

  17. Marygrove College All in house – your looking at the main resource!

  18. Job Duties • How has system administration (tuning, parameters, maintenance, etc.) changed from a Unidata perspective to SQL? • Has there been an impact to staffing the System Administrator, Programmer/Analyst and other positions?

  19. Contra Costa Community College District • No more WUFA • Windows maintenance • Occasional SQL Reindexing and Defrag • No impact to Staffing • Training was conducted during the migration project

  20. Marygrove College • System administration close to the same • Patching is the same • More work since two servers compared to one • I still do a lot of my work at the : • On the rare occasion, I use SQL • System Administrator does a lot of work on SQL Staffing Impact • has skill set in SQL more so than Envision • Trying to get IT staff to adopt Envision more

  21. Lessons Learned • What would you have done differently?

  22. Aftermath • Did anyone involved in the migration experience serious physical injuries, loss of mental capacity or were otherwise impaired as a result of the migration?

  23. Contra Costa Community College District • “Daniel and I used to be friends…” • Before • During • After

  24. Questions • Questions from the audience?

  25. Thank You!
