  1. Licensing Infrastructure Issues Solutions Experience Matthias Schröder for N.Høimyr, M.Katzarova, P.Saiz, A.M.Osborne, A.Thys, P.Bähler, H.Hansbakk

  2. Issues • Commercial software requires licences • Several schemes possible • Single user • Node locked • Network/Floating • Site wide • Home use Matthias Schröder - Licensing Infrastructure

  3. Management Aspects • Licences need to be managed • Purchase the correct number • Too few: users are very unhappy • Too many: your management is very unhappy • Install them • Keep them accessible • Renew them in time • Warn the product maintainer, so he can take action • Retire unused versions Matthias Schröder - Licensing Infrastructure

  4. Service Issues • Appropriate Infrastructure needed • Assure availability • Monitor usage • Adapt number of licences to usage • Inform about issues • Make sure you can contact the users • Keep track of available products • 120 products in database • Products can have many features Matthias Schröder - Licensing Infrastructure

  5. Licence Management Systems • Challenge: many different systems • Macrovision FlexLM • IBM LUM • Wolfram MathLM • Microsoft SMS logs • Many proprietary systems • No common interface • Some are plain incompatible • Require different operating systems • Some require hardware keys Matthias Schröder - Licensing Infrastructure

  6. Our Setup Log parser Clients Licence servers Web- interface Product database Matthias Schröder - Licensing Infrastructure

  7. Log Parser • Read logfiles of different license managers • Each with own format… • ~ 1k lines of perl, C or shell per parser • Extract needed information and store in DB • Which product, feature, version • Used by whom, when, from which host • Provides unified interface • Long term storage in DB • Easy access Matthias Schröder - Licensing Infrastructure

  8. Web Interface – Product Information Matthias Schröder - Licensing Infrastructure

  9. Web Interface – Product Maintainer Page Matthias Schröder - Licensing Infrastructure

  10. Usage Monitoring • Do we have enough/too many licences? • Maximum number of concurrent users • Number of denials • For the different operating systems • For the different versions of the product Matthias Schröder - Licensing Infrastructure

  11. Usage Monitoring 2 • Lists of users • Current users • Ask user X to free a licence for Y • Warn them about imminent changes • Recent users • Inform about planned changes, downtimes • With email address Matthias Schröder - Licensing Infrastructure

  12. Web Interface - Statistics Version 6.4 of TotalView not used anymore, consider retirement Matthias Schröder - Licensing Infrastructure

  13. Web Interface - Statistics Matthias Schröder - Licensing Infrastructure

  14. Server Monitoring • Availability of Service very important • Systems must be up at all times • Licence manager daemons as well • Have redundant servers • 2*3 Solaris • 3+1+1+1 Windows • Not all licence managers allow fallback setup • Monitor servers and daemons and start/stop daemons • If vendor is not flexible enough: no fallback Matthias Schröder - Licensing Infrastructure

  15. If things go wrong • Problems in fetching a logfile • No stats for a product for that week Matthias Schröder - Licensing Infrastructure

  16. If things go wrong • Problems in parsing a logfile • Strange results… Matthias Schröder - Licensing Infrastructure

  17. Conclusion • Proper infrastructure helps managing licences • Monitoring essential for estimate of needs • Variety of licence managers does not ease task • Log parsers help in dealing with variety Matthias Schröder - Licensing Infrastructure
