Java & SOA Cloud Service for Fusion Middleware Administrators
2 likes1,264 views
The document outlines the Java and SOA cloud services available for middleware administrators, highlighting their features, provisioning, and administrative options. It emphasizes the shift to a 'pay as you go' model, automated software provisioning, and the role of middleware administrators in managing these services. Administrators are expected to focus more on high-value tasks such as deploying applications and optimizing performance, while the platform manages routine operations.

- 11. Choices for Full JCS or JCS-VI Billing Frequency WebLogic (Edition & Version) WebLogic Cluster size & ‘Shape’ of VMs(s) (optional) Coherence (optional) Oracle Traffic Director
- 15. What does a small JCS cluster look like? E.g. 5 VMs: ◦ 1 Traffic Director ◦ 2 WebLogic ◦ (optional) 2 or more Coherence (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
- 16. 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. Provisioning Choices for SOA CS Product / domain type Compute shape (MS high memory, from OC3M) (optional) Oracle Traffic Director
- 18. SOA CS – Topology Choices
- 19. Provisioning Constraints for SOA CS Monthly only billing (at moment?) SOA 12.1.3.0.1 (currently) ◦ plus a cloud adapter patch + another interim patch ◦ built on top of JCS 12.1.3.0.4 (July CPU+ 3 interim patches) Coherence within MS Full JCS only
- 20. DEMO
- 21. Admin Server Managed Server 1 Traffic Server Admin Server Managed Server 2 Firewall (NAT/PAT) Routing 10.5 2.5 10.5 15 15 7.5 Memory for example OC3M config for managed servers & OC3 for LB GB
- 22. Thoughts aboutTopology Combined admin server & managed server 1 One managed server per VM ◦ Can’t do EDG-style separate WSM-PM, ESS, BAM without additional VMs No shared storage (other than object stores) ◦ JMS, JTA can go in database, but have to synchronise deployment plans & other configuration manually (will drive changes to SOA?)

- 24. Tailor the Environment Set up SSL certificates Set up security providers Changes to Server Start parameters, setUserOverrides.sh Manage storage space 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
- 25. 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’ SOA CS is same as built on top of JCS
- 26. 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
- 27. 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 No SOA CS patches yet to see
- 29. 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) SOA CS REST APIs are apparently coming soon
- 30. 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
- 31. Sometimes I can’t help myself…
- 32. My experiment Set up a cron job running every minute to write VM time and global time (via a REST API on internet) into a log file 1) manually move VM clock forward 10 seconds (not so brave!) ◦ Reboot fixed time, but not totally clear where 2) move VM clock forward 1 hour so I could see exactly where there was a 1h jump back! ◦ Reboot fixed time actually at the instant of VM startup (i.e. before OS)
- 33. Result VM clock gets sync’d with host on VM boot I assume underlying hosts are NTP sync’d (or similar) Is it possible for clock to drift??? ◦ VM is managing its time independently so doesn’t rely on Dom0 ◦ Possible study for another day Probably good enough, at least for now… JCS VMs are HV PVM xen.independent_wallclock = 1

- 44. 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
- 45. 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/
- 46. 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

- 50. Summary JCS/JCS-VI gives you power/flexibility of WebLogic including most of the control you are used to SOA CS provisions SOA quicker than almost any other way Oracle PaaS viable for various uses, providing you can live with design decisions 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!
