#3 Prerequisites for JCS

Slide 14

Slide 14 text

Prerequisites • Write down all the passwords (they have different requirements) • ID domain • Storage container name • Use lower case emails for user names Keep the first temp password: If you change from classic to bare metal you need it @frankmunz

Slide 15

Slide 15 text

Prerequisites JCS will never work, unless you … 1. Set replication policy for storage 2. Create DB as a service for JCS 3. Create JCS @frankmunz

Slide 16

Slide 16 text

#4 (1) Replication Policy

Slide 17

Slide 17 text

Go to Storage & Set Policy @frankmunz You will only see this screen only once! Not setting the policy causes all kind of weird issues

Slide 18

Slide 18 text

Prereq: Set Replication Policy Details: https://docs.oracle.com/en/cloud/iaas/stora ge-cloud/cssto/selecting-replication-policy- your-service-instance.html Customer feedback: Oracle should set replication with working default @frankmunz

Slide 19

Slide 19 text

#5 (2) DB

Slide 20

Slide 20 text

Prereq: Create DB as Service A DB is mandatory for JCS @frankmunz Define DB pwd Specify Cloud log-in creadential Create Storage Container

Slide 21

Slide 21 text

Storage Container Correct syntax / name of storage container: Storage-IDENDITYDOMAIN/yourContainerName @frankmunz You create it once (with the DB). Later specify it at JCS configuration

Slide 22

Slide 22 text

Identity Domain Tip: Always save your Cloud Welcome Email @frankmunz ABCDomain

Slide 23

Slide 23 text

In the Same Email: Data Center Most OPC links DC agnostic, but storage is not: @frankmunz

Slide 24

Slide 24 text

Resend Welcome Email @frankmunz

Slide 25

Slide 25 text

Wait Until DB is Created @frankmunz Customer feedback: If JCS requires DB, why is it not automatically created?

Slide 26

#12 More Lessons Learned

Slide 49

Slide 49 text

There is more • OTD as frontend recommended • JCS comes with default certificates -> not suitable for production • Follow SOA CS Disaster Recovery Guide @frankmunz http://www.oracle.com/technetwork/database/availability/maa-soacs-dr-3125213.pdf

#14 Spring Boot

Slide 54

Slide 54 text

Spring Boot • Not WebLogic or Java EE compatible • Not standard, but often used • It’s a fat jar • Runs in Oracle ACCS and AWS Beanstalk • Even with Kotlin @frankmunz http://www.munzandmore.com/2017/ora/kotlin-spring-boot-aws-beanstalk-oracle-cloud
