- 30. First Obstacles
- 31. 31 Multi-Tenancy Problem: No “out-of-the-box“ support for tenants in Activiti
- 32. IHK101 … IHK106 IHK106_05 Oracle DB … Glassfish Node 1 ENTW QS … Process Engine 101 Process Engine 106 Multi-Tenancy Tenant derivable from user name: 101joerges
- 33. 33 Multi-Tenancy Solution 1: ALTER SESSION SET CURRENT_SCHEMA and custom JDBC data source
- 34. 34 Multi-Tenancy Solution 1: ALTER SESSION SET CURRENT_SCHEMA and custom JDBC data source Bad performance!
- 35. 35 Multi-Tenancy Solution 2: Use of database table prefixes in Activiti (ACT-565), since Activiti 5.10
- 36. 36 Multi-Tenancy <!– Tenant 101 --> <bean id="processEngineConfiguration101" class=… > <property name="processEngineName" value="101" /> <property name="dataSource" ref="containerDataSource" /> … <property name="databaseTablePrefix" value="IHK101." /> </bean> <!– Tenant 106 --> <bean id="processEngineConfiguration106" class=…> <property name="processEngineName" value="106" /> <property name="dataSource" ref="containerDataSource" /> … <property name="databaseTablePrefix" value="IHK106." /> </bean> activiti.cfg.xml:
- 37. 37 Multi-Tenancy ProcessEngineConfiguration config = ProcessEngineConfiguration .createProcessEngineConfigurationFromResource( "activiti.cfg.xml", "processEngineConfiguration101"); ProcessEngine engine101 = config.buildProcessEngine();
- 38. 38 Multi-Tenancy Solution 3: fox platform Process engines do not have to be managed manually.
- 39. 39 Query API Problem: Activiti‘s on-board query API not suitable for our requirements
- 41. 41 Query API Disadvantage 1: Not all required queries could be constructed via the query API Example: All tasks with „101joerges“ being the owner or the assignee.
- 42. 42 Query API Disadvantage 2: Aggregate selections are expensive because multiple queries are required Bad performance Pagination difficult
- 43. 43 Query API Solution: Define custom MyBatis queries! (see Fox User Guide → „Performance Tuning with custom Queries“) Good performance (factor 10!) Pagination works Custom queries have to be maintained
- 44. fox platform
- 45. 45 Reasons for Changing Process Applications → JEE-style process deployment → Processes are collected in WARs → Services can be collected in dependent JARs
- 46. 46 Reasons for Changing Platform Job Executor → better configurability (job aquisition, multiple process engines) → application server integration (e.g. thread pools)
- 47. 47 Architecture (fox engine only)
- 48. 48 Architecture (with fox platform)
- 49. Conclusion
- 50. 50 Conclusion Activiti-based fox platform is a flexible BPM solution that is ready for enterprise scenarios
- 51. 51 Conclusion Thanks to open source: React to specific requirements by just doing it yourself.
- 52. 52 Conclusion Thanks to open source: React to specific requirements by just doing it yourself. Or by asking the community.
- 53. 53 Conclusion Thanks to open source: React to specific requirements by just doing it yourself. Or by asking the community. Or camunda.
- 54. 54 Next Steps Status of EVA Fallmanagement: Infrastructure is available First client (EVA) is realized “Show cases“ under construction Goal: Productive for first customers in early 2013
