Managing SOA CS domains with Myst

A SOA Cloud Service (SOA CS) environment can be introspected to create a Platform Blueprint and Platform Model.

The article will guide users through the introspection process specifically for SOA CS environments.

Infrastructure Provider

Create a Cloud Infrastructure for MyST to access the SOA CS environment.

1. Hover over Discover and click Cloud Services
2. Click Discover > Cloud Infrastructure

3. Enter a Name such as Default

4. Click
5. Enter the Name and Private Key Content and click
6. Click
7. Enter the Name, SSH User Name, Key Pair

8. Select Yes for Run as different user and enter oracle as the Other User Name
9. Click
10. Retrieve the Public IP from your Oracle Cloud account
11. Enter Name, Host Name and select Compute Logical Definition, Environment, OS Agent Credential
12. Click to validate the SSH connection is successful then click
13. Click

Discovery

The discovery process reads the SOA CS environment into MyST.

1. Hover over Discover and click Cloud Services
2. Click Discover > Soa Cloud Service

3. Enter a Name and click
4. Enter the Domain home directory, Platform Model, and Password and click Discover
5. After the discovery finishes loading click
6. Review your instance definition and click

Blueprint

1. Click Manage > Platform Blueprints
2. Select the SOA 12.2.1.2 Blueprint

3. Below are the Blueprint configuration changes to align MyST with SOA CS

Location	Property	MyST Value	SOA CS Value	Notes
WebLogic Domain Configuration > Coherence Clusters > defaultCoherenceCluster	Cluster Listen Port	9991	7574	SOACS uses 7574 while SOA on-premise was 9991
WebLogic Domain Configuration > WebLogic Deployment Targeting > Applications > wsm-pm	Targets	AdminServer, soa_cluster	AdminServer	(Optional) Remove the soa_cluster so only the AdminServer is targeted
WebLogic Domain Configuration > JDBC Data Sources > All OOTB	Test Table Name	SQL SELECT 1 FROM DUAL	SQL ISVALID	(Optional) Set the value for each out of the box (OOTB) Data Source
WebLogic Domain Configuration > JDBC DataSources	wlsbjmsrpDataSource	N/A	Name, Targets, JDNI Name, and Driver Class Name	(Optional) Only necessary if users want to change configuration for wlsbjmsrpDataSource
WebLogic Domain Configuration > JCA Adapters	Outbound Connection Properties	N/A	Any properties	MyST currently does not introspect Outbound Connection Properties. Add if you have any JCA Adapters configured.
WebLogic Domain Configuration > Clusters	Cluster Address	Auto computed by MyST	Auto computed by MyST (cannot be removed)	(Optional) MyST computation requires the Cluster Address to always be set
WebLogic Domain Configuration > AdminServer > Default Store	Directory	${[rxr.wls.Domain-1].shareHome}/tlogs	${[rxr.wls.Domain-1].domainAserverHome}/servers/${[rxr.wls.AdminServer-1].name}/data/store/default	By default TLOGS are not defined in the WLS Console. In MyST we set them to their default directory.
WebLogic Domain Configuration > Managed Servers > Default Store	Directory	${[rxr.wls.Domain-1].shareHome}/tlogs	${[rxr.wls.Domain-1].domainAserverHome}/servers/${[rxr.wls.ManagedServer-1].name}/data/store/default	By default TLOGS are not defined in the WLS Console. In MyST we set them to their default directory.

Validation

Dry Run

After the discovery and configuration of a Blueprint it is good practice to validate the changes against the SOA CS environment. A dry run functionality mimics the configuration applied by MyST and outputs the changes. Below is an example of changes to the Cluster Address and a JDBC Datasource.

Check For Drift

MyST has a check for drift function to compare the current MyST Platform Instance against the SOACS environment.

Below are safe and optional properties/values which can be used as MyST defaults in the Blueprint. They are the optional properties taken from the table above in the Blueprint section.

Location	Property	MyST Value	SOACS Value
WebLogic Domain Configuration > WebLogic Deployment Targeting > Applications > wsm-pm	Targets	AdminServer, soa_cluster	AdminServer
WebLogic Domain Configuration > JDBC Data Sources > All OOTB	Test Table Name	SQL SELECT 1 FROM DUAL	SQL ISVALID
WebLogic Domain Configuration > JDBC DataSources	wlsbjmsrpDataSource	N/A	Name, Targets, JDNI Name, and Driver Class Name
WebLogic Domain Configuration > Clusters	Cluster Address	Auto computed by MyST	Auto computed by MyST (cannot be removed)

FAQ

Question: Does MyST support an administrative user other than the weblogic username?

Answer: No, at this point a weblogic username is required. Admins can create an additional weblogic user.
