3. Overview Process Deployment Architecture Debugging WLS Administration Performance Security Scripting

4. Process Integrate early and often on a cluster Test as early as possible on deployment platform and configuration Development team needs build manager Deploy so you can roll back Model production in your QA environment

5. Deployment Architecture KISS Have a good reason before splitting the presentation and object tier Consider WebLogic Express Premium Prove a real improvement before using Apache for static content

6. More Deployment Beware giving servers different internal and external names Evaluate deployments on the admin server Use domains as an administrative constraint

7. Debugging Administration.wlnotdelete and stage Firewalls and JDBC pool shrinking One WLS version in QA and production Upgrade WebLogic Backup config.xml Beware the console domain wizard

8. More Debugging Admin Remember licenses are IP bound Licenses at http://elicense.bea.com, can be misleading (CPUs and products)http://elicense.bea.com ClassCastException and ClassNotFoundErrors are usually problems in deployment architecture NotSerializableExceptions – look for objects going into Session not tested on a cluster

9. More Debugging Admin Use shutdown, not kill –9 Search esupport and Google groups for problems When contacting support, fill out the whole form Deadlocks – kill –3 Use your salesrep for real support problems

10. Performance Focus on object tier -> DB for CRUD apps Spend $$s on network and DB machine Set headers and cache images Use replication in groups in large clusters Set max size in connection pool to max number of users

11. Security http://dev2dev.bea.com/advisories Permissions Restrict size and time limit on connections Password protect the JDBC connection pools to a role Enable security auditing

12. More Security Don’t allow JSPs in production to have keepgenerated = true No builds / no source Don’t enable the Servlet servlet in production Do not leave the FileServlet as the default servlet

13. Scripting Write shell scripts to control disparate servers Use MBeans to ensure consistent configurations
