Yes, SOA Mbeans can be configured using MyST Studio. Additionally, BPEL EJB transaction timeouts can be set.

BPEL EJB Transaction Timeout

See more information in Oracle document 880313.1.

These instructions can also be found here: Can I configure EJB Transaction Timeout through MyST

Step 1:

NOTE: This property is applied via the MyST 'update' action only when soa-infra is shutdown.

1. Modeling > Platform Blueprint
2. Click Products > Oracle SOA Suite
3. Add a parameter
   
4. Shutdown the SOA managed servers in order to apply these changes
5. Run the MyST 'update' action to apply changes to soa-infra application

SOA MBEANs

Below is a working example for configuring some of the commonly tuned SOA Mbean properties.

NOTE: These properties are applied via the MyST 'configure-soa' action and when soa-infra is running.

Step 1: Edit the Platform Blueprint

1. Navigate to the Platform Blueprint which you want to change in MyST Studio ("Modeling" > "Platform Blueprints")
2. Click "Edit Configuration"
3. Go to "Global Variables".
4. Click "Edit" then "Edit Bulk".
5. Add the following properties.

   oracle.sysman.emas.discovery.wls.FMW_DISCOVERY_MAX_CACHE_AGE=2592000000
   oracle.sysman.emas.discovery.wls.FMW_DISCOVERY_MAX_WAIT_TIME=1800000
   oracle.sysman.emas.discovery.wls.FMW_DISCOVERY_USE_CACHED_RESULTS=true
   LargeRepository=true
   

6. Click "Done" then "Save".
7. Go to "Products" > "Oracle SOA Suite".
8. Click "Edit" then under "Name-Value Parameters" click "Edit Bulk".
9. Add the following properties. (Note: audit-level should already exist so only needs to be edited - not created)

   audit-level=Production
   bpel-AuditLevel=production
   bpel-BpelcClasspath=/u03/app/oracle/admin/domains/tbpm5_domain/mserver/tbpm5_domain/lib/gen_credentials_client-1/0.jar:/u03/app/oracle/product/12.1.3/tbpm5_domain/soa/soa/modules/oracle.bpm.composer.webapp_11.1.1/commons-codec-1.2.jar
   bpel-RecoveryConfig.RecurringScheduleConfig.maxMessageRaiseSize=50
   bpel-RecoveryConfig.RecurringScheduleConfig.startWindowTime=00:00
   bpel-RecoveryConfig.RecurringScheduleConfig.stopWindowTime=23:59
   bpel-RecoveryConfig.RecurringScheduleConfig.subsequentTriggerDelay=900
   bpel-RecoveryConfig.StartupScheduleConfig.maxMessageRaiseSize=0
   bpel-RecoveryConfig.StartupScheduleConfig.startupRecoveryDuration=0
   bpel-RecoveryConfig.StartupScheduleConfig.subsequentTriggerDelay=900
   bpel-SyncMaxWaitTime=200
   bpmn-RecoveryConfig.RecurringScheduleConfig.maxMessageRaiseSize=0
   bpmn-RecoveryConfig.RecurringScheduleConfig.startWindowTime=00:00
   bpmn-RecoveryConfig.RecurringScheduleConfig.stopWindowTime=00:00
   bpmn-RecoveryConfig.RecurringScheduleConfig.subsequentTriggerDelay=900
   bpmn-RecoveryConfig.StartupScheduleConfig.maxMessageRaiseSize=0
   bpmn-RecoveryConfig.StartupScheduleConfig.startupRecoveryDuration=0
   bpmn-RecoveryConfig.StartupScheduleConfig.subsequentTriggerDelay=900
   soa-infra-EMDurationWindowUnits=minutes
   soa-infra-EMDurationWindowVal=1
   workflow-AcknowlegdeFyiUponRead=false
   workflow-HWFFailureRetryCount=1
   workflow-MaxNumberOfEmailAttachments=-1
   workflow-MaxSizeOfEmailAttachmentsInKB=1
   

10. Click "Done" then "Save".
11. Go to "WebLogic Domains" and expand the domain.
12. Then, go to "WebLogic Clusters" and click on the SOA cluster.
13. Set the "Frontend Host" to `acme.soacorp` and "Frontend Http Port" to 80.
14. Click "Save".
15. Click "Apply Changes"

Step 2: Update Platform Model based on the Blueprint changes

1. Go "Modeling" > "Platform Models"
2. Select the Platform Model corresponding to the previously edited Platform Blueprint
3. Go to "Actions" and select "Update" In the dialog box select "Update to latest draft" (assuming the Platform Blueprint was edited in the same version that the model is currently on).
4. Click "Update".

Step 3: Run Configure SOA Action

Now that the Platform Model has been updated to incorporate the recent Platform Blueprint changes, we can run the Configure SOA action.

1. From the Platform Model go to to "Actions" and select "Control"

2. Select the "Custom" action and enter the "Command" as configure-soa.

3. Click "Execute"

4. Once the action has completed click "View" under "Execute Log" to see the changes made.

Configure SOA advanced properties as part of Provisioning

The above SOA configuration step can be configured to automatically run at the end of platform provisioning by adding action.configure.post=configure-soa in the Global Variables of the Platform Blueprint
