What should I do now?! JCS for WebLogic Admins
0 likes1,446 views
The document discusses the Java Cloud Service (JCS) and its relevance to WebLogic administrators, focusing on its features such as automated provisioning, a pay-as-you-go licensing model, and management through REST APIs. It emphasizes the shift in the role of middleware administrators toward higher-value tasks and the need for operational oversight in cloud environments. Additionally, it provides insights on performance management, backup, high availability, and the expectations of the business from IT services.
What should I do now?! JCS for WebLogic Admins
- 1. Java Cloud Service for WebLogic Administrators Oracle OpenWorld, San Francisco October 2015 What should I do now?!
- 2. Simon Haslam Consultant, Veriton Working with Oracle software since 1995 (and AWS since 2010) Middleware & SOA WebLogic, SOA, BPM and Java Cloud Service Specialist Veriton UK-based consultancy, focussed on Oracle infrastructure
- 4. Presentation objectives & themes Describe Java Cloud Service New Opportunities for the WebLogic Administrator
- 5. Java Cloud Service overview Provisioning JCS Instances WebLogic Administration in JCS
- 6. Java Cloud Service – what is it? WebLogic Servers running in Oracle Cloud ◦ Plus supporting software: Oracle Traffic Director, Coherence, Database New “pay as you go” licensing model Automated software provisioning, plus…

- 10. Choices for Full JCS or JCS-VI Billing Frequency WebLogic (Edition & Version) WebLogic Cluster size & ‘Shape’ of MS cluster node(s) (optional) Coherence (optional) Oracle Traffic Director (full JCS only) Storage Container
- 13. DEMO
- 14. What does a small JCS cluster look like? E.g. 5 VMs: ◦ 1 Traffic Director ◦ 2 WebLogic ◦ 2 Coherence (optional; 3 is more “Coherence-friendly”) One domain including: ◦ WebLogic & Coherence clusters ◦ Node Managers ◦ FMW Infrastructure, including schema in DB ◦ Demo SSL certificates ◦ An OTD virtual host to the WLS Cluster A default backup schedule
- 15. Admin Server Managed Server 1 Traffic Server Admin Server Managed Server 2 Coherence Server 1 Coherence Server 2 Firewall (NAT/PAT) Routing 5.02.5 2.5 2.5 5.0 7.5 7.5 7.5 7.5 7.5 Memory for example OC3 config GB

- 17. Tailor the Environment Set up SSL certificates Changes to Server Start parameters, setUserOverrides.sh (setDomainEnv.sh) Manage storage Adding further clusters/nodes etc ◦ See “Keeping Your Service Instances Manageable by Oracle Java Cloud Service” http://docs.oracle.com/cloud/latest/jcs_gs/JSCUG/GUID-68749D52-DAC9-44E7-90AD- 6C891300156E.htm#JSCUG3281
- 18. Directory structure ORACLE HOME: /u01/app/oracle/middleware JDK HOME: /u01/jdk DOMAIN HOME: /u01/data/domains/<domain-name> Others: ◦ /u01/data/backup – backup location ◦ /u01/app/oracle/tools – Oracle ‘cloud tooling’
- 19. Backup / restore Backup types ◦ Binaries plus domain configuration ◦ Domain only (aka ‘incremental’) ◦ Database can be included too (creates an RMAN tag in DBCS instance) Schedule ◦ Weekly full & daily incremental by default Location and Retention Policy ◦ Held locally for a week, then moved to Storage Service ◦ Retained for 30 days by default Backups are encrypted (using a key known only to OPC) Full JCS only
- 20. Patching WebLogic PSUs plus JDKs JCS backs up beforehand and can rollback later (all?) Patches are rolling (if you have load balancer) Each Managed Server is: 1. backed up 2. removed from Traffic Director origin server pool 3. shut down 4. JDK or Oracle Home replaced with a patched image 5. restarted 6. added back to Traffic Director pool Full JCS only
- 21. JCS Management Provisioning/managing non-trivial JCS platforms will mostly be using REST APIs ◦ Everything in OPC console can be done via REST APIs ◦ REST tools (browser plug-ins like Postman or RESTClient, curl etc) and JSON format are quick/easy to learn All your existing tools/techniques still work with JCS ◦ Connecting to Node Manager ◦ Java Mission Control & other JVM diagnostics tools ◦ Enterprise Manager 12c (Hybrid Cloud Agent etc)
- 22. QuickTips Naming conventions Key management The Oracle product filesystems are overwritten (swapped) during patching – don’t put any of your own files in there! ◦ e.g. EM agent Set up disk free space alerts

- 24. Presentation objectives & themes Describe Java Cloud Service New Opportunities for the WebLogic Administrator
- 25. How do you provision today? Manually ? Automated s/w only? Automated s/w + initial domain? Fully automated ?
- 26. Recognize this? Better than nothing, but this is like typing in code every time you want to run a program!
- 27. … use one of these instead!
- 28. How do you deploy today? Manually ? Scripts ? Continuous Integration for test? Fully automated CI / SD?
- 29. Deployment There are LOTS of tools to help (including previous tools) – pick something!
- 30. Survey: Middleware Admins & DBAs
- 31. Results* * This was not a scientific survey – 20 responses to my twitter requests
- 32. Results* * This was not a scientific survey – 20 responses to my twitter requests CI / CD Tuning ToolsPredictive Alerting EM, snaps Assisted Help? Rolling patching Done by PaaS Post-cloud influences & time savers Can your custom apps be replaced by SaaS ?
- 33. Oracle PaaS Admin.Tasks for your Org. Platform Design ◦ Sizing / costing ◦ Naming conventions (as important as ever) ◦ Capacity planning Operations ◦ Application Deployment ◦ Performance Assurance and Tuning ◦ Monitoring and management PaaS is intended to be used by administrators, not power users Someone still has to be responsible for mission-critical systems
- 34. Consumption Someone needs to monitor consumption As for all cloud services… ◦ It’s (too?!) easy to spin up new environments ◦ Do they all need to be running? Consider monthly vs hourly ◦ Hourly is +25% but if instance only used 8h/day then 42% of monthly cost Consider JCS vs JCS-VI Image credit: http://cropmetrics.com/2013/11/gas-gauge-analogy-cropmetrics-water-management/
- 35. What does this mean for your role as Middleware Administrator? Middleware administrators don’t spend that much time on installing software / creating domains Highest value work is rolling out new applications/features & fixing performance of existing ones If we looked further down the stack expect a different picture e.g. sys admins, virtualization admins, storage admins
- 36. What does the Business want? • Backup • High availability & DR • Environments • Upgrades & patching • Monitoring • Have what they want • New func. as soon as $ • Justifiable cost • Compliance • “on” like Facebook IT Business
- 37. What does the Business want? • Backup • High availability & DR • Environments • Upgrades & patching • Monitoring • In-house IT • Have what they want • New func. as soon as $ • Justifiable cost • Compliance • “on” like Facebook Our job is to enable this! Focus on Adding Value Business

- 39. Summary Full JCS is here & viable for many types of workload JCS/JCS-VI gives you power/flexibility of WebLogic including most of the control you are used to You will be doing far less menial, low-value work – make yourself more valuable! …but someone still has to be responsible for your Oracle platforms… you!
