Example environment settings for NexJ CRM deployment

The following are example environment settings for a typical NexJ CRM deployment on Model Server.

For information about environment setting values for IBM WebSphere, see Example environment settings for NexJ CRM deployment in the deployment documentation for the 8.9 release.

For detailed descriptions of all environment properties, see the Environment topic in the Model Description Language Reference at https://community.nexj.com/documentation/reference/modl/latest/Environment.html.

Specifying environment settings

You can specify all environment variables in a single .environment file or use an environment file as a template in combination with a .properties file. For more information, see Creating environment files.

Using the environment file as a template is the recommended method. For more information, see Using the environment file as a template with .properties files.

Using the environment file as a template with .properties files

You can use the example environment file above to create an environment file that can be used as a template for multiple environments. It would be similar to the example, but some of the values would be replaced with variables. For example, in the example environment file above, a relational database connection could be defined with the following settings:

XML

<RelationalDatabaseConnection adapter="MSSQL" database="finance" host="localhost" password="nexj" path="jtds-1.2.2-9.jar" port="1433" user="nexj">

In an environment file used as a template, it would be defined with the following settings instead:

XML

<RelationalDatabaseConnection adapter="${RelationalDatabaseConnection.Adapter}" database="${RelationalDatabaseConnection.DEF.Db.Name}${test.clone}" host="${RelationalDatabaseConnection.Db.Host}" password="${RelationalDatabaseConnection.Db.Password}" path="${RelationalDatabaseConnection.Db.Path}" port="${RelationalDatabaseConnection.Db.Port}" user="${RelationalDatabaseConnection.Db.User}">

You would then also need to create one or more .properties files that refer to specific databases used in different deployment environments. For example, you can create a DeploymentMSSQL.properties file that contains the following code:

XML

RelationalDatabaseConnection.Adapter=MSSQL
RelationalDatabaseConnection.DEF.Db.Name=finance
RelationalDatabaseConnection.Db.Host=localhost
RelationalDatabaseConnection.Db.Password=nexj
RelationalDatabaseConnection.Db.Path=jtds-1.2.2-9.jar
RelationalDatabaseConnection.Db.Port=1433
RelationalDatabaseConnection.Db.User=nexj
config=Deployment.environment

You could also create a DeploymentOracle.properties file that contains the following code:

XML

RelationalDatabaseConnection.Adapter=Oracle11g
RelationalDatabaseConnection.DEF.Db.Name=finance
RelationalDatabaseConnection.Db.Host=localhost
RelationalDatabaseConnection.Db.Path=ojdbc14.jar
RelationalDatabaseConnection.Db.Port=1521
RelationalDatabaseConnection.Db.User=nexj_dba
config=Deployment.environment

Note that both of these .properties files also specify the config setting, which refers to the environment file that is being used as a template.

All the settings described in this topic and in the Model Description Language Reference can be included in an .environment file used as a template, either with either variable or constant values.
