Scripted Domain Creation for SOA/BPM, OSB 12.2.1

Recently I blogged about the automatic install of SOASuite and ServiceBus 12.2.1. It catered for the installation of the binaries and the creation of a repository.

What it does not handles is the creation of a domain. The last few weeks I worked on a script to do that. It's based on a wlst script for 12.1.3 by Edwin Biemond. This one was quite educational for me. But as denoted: it was made for 12.1.3. And I wanted more control on what and how certain artefacts are created. So gave it my own swing, also to adapt it for some wishes of my current customer.

Although there are certainly some improvements thinkable, and probably will be done in future uses, for now it is ready to share with the world.

One of the changes I did was to divide the main function in sections to make clear what the structure of the script is. I also moved some of the duplicate code or functional parts into separate functions.

Let me describe the sections first.

1. Create Base domain

The script starts with creating a base domain. It reads the default wls template 'wls.jar'. Sets the log properties of the domain. It then adapts the AdminServer to

• change name as set in the property file: you can have your own naming convention.
• change listen addres + port
• Set default SSL settings
• Set log file properties.

Then set the admin password on the domain and set the server start mode. Save the domain.
It then creates boot.properties files for nodemanager and AdminServer and set the password of the NodeManager. Finally setting the Applications home folder.

2. Extending domain with templates

The second section extends the domain with templates. Another improvement I did is that you can select which components you want to add by toggling the appropriate 'xxxEnabled' switches  in the property file, where xxx stands for the component (for instance 'soa', 'bpm', 'osb', 'bam', 'ess', etc.)

It supports the following components:

• ServiceBus
• SOA and BPM Suite and B2B
• BAM
• Enterprise Scheduler Service

Components such as  Managed File Transfer can be added quite easily.

3. DataSources

Section 3 takes care of setting the datasources to the created repository based on the repository user '{Prefix}_STB', via the 'LocalScvTblDataSource' datasource. In the property file you need to set

• soaRepositoryDbUrl: jdbc connect string to the repository database
• soaRepositoryDbUserPrefix=prefix used in the Repository creation 
• soaRepositoryStbPwd=Password for the {Prefix}_STB user.

 It will adapt the LocalScvTblDataSource with these properties to load the information on the other repository users to create and adapt the datasources that are essential to the modules with which the domain is extended. These datasources are then made XA-Enabled.

4. Create UnixMachines, Clusters and Managed Servers

This section creates Machine definitions of type 'Unix', based on the properties:

• server1Address=darlin-vce-db.darwin-it.local
• server1Machine=darlin-vce-db
• server2Enabled=true
• server2Address=darlin-vce-db2.darwin-it.local
• server2Machine=darlin-vce-db2

The machine denoted with 'server1Machine' is created always. The AdminServer is added to it, as well all the first, default, managed servers. The machine denoted with the property 'server2Machine' is only created when 'server2Enabled' is set to true.

I realize that 'server' in this context might be a little confusing. In serverYAddress and  serverYMachine, I actually mean a server-host, not a managed or admin server.

 For each component to configure (soa, osb, etc.) a cluster, denoted with for instance osbClr or soaClr, is created.

When you extend the domain with SOA Suite or OSB then automatically a managed server called 'soa_server1' or 'osb_server1' created with the appropriate deployments targeted to it. In the script of Edwin these are removed and new ones are created. I found problems with that and found that it's quite unnecessary, since we can rename the current ones with the given name in the property file, denoted with soaSvr1 or osbSvr1, etc., as is done with the AdminServer. So I leave the already created ones, but rename them to the desired value.

These first servers are added to the appropriate cluster, what causes to re-target the deployments to that cluster, magically.

Then if enabled, as with osbSvr2Enabled or soaSvr2Enabled, etc., the particular 'second' servers are created and added to the particular cluster.

5. Add Servers to ServerGroups

New in 12c is the concept of ServerGroups. In 11g you had only one definition of USER_MEM_ARGS in the setDomainEnv.sh/cmd. So these counted for each server (admin or managed) that are started using the start(Managed)Weblogic.sh/cmd scripts. But in 12c the determination of the USER_MEM_ARGS are done in a separate script: setStartupEnv.sh/cmd.
In this script the determination is done based on so-called ServerGroups. This provides a means to differentiate in memory settings for the particular servers, which was lacking in 11g.

So in this sections all the Managed and Admin Servers are added to a particular ServerGroup.

6. Create boot properties files

Lastly, for each created managed server a boot.properties file with the username password is created. Smart: I used to do this every single time by hand...

The example property file

Conclusion

As said, although I think this script is already quite adaptable using the property file, of course there are many improvements thinkable for your particular situation. It creates a 'skeleton' SOA or Service Bus domain, but you might need to adapt for network topologies, security settings.
And although it creates a 'per domain' nodemanager configuration, you would need to adapt it for your particular needs to get the domain started. I only tested this by starting the Admin server using the startWeblogic.sh script.

Having such a script is such  a valuable asset: it allows you to (re-)create your domains repeatably in a standard way, ensuring that different environments (dev, test, acc, prod) are created similarly.

One, last thing though, the script somehow registers the creation of the domain and thus the use of the datasources in the repository. So you can't just throw away the domain and recreate it to the current Repository. You'll need to rereate the Repository as well.
