|| Installation archive || Default environment configuration file ||
| ZIP archive | {{$PETALS_HOME/conf/env.sh}} |
| Debian package | {{/etc/petals-esb/default-env.sh}} |
For all installation, the default environment configuration file can be updated to adjust parameters to your environment. But for a Debian-based installation, it is recommended to create your own environment configuration and define it in the configuration of your Petals ESB container through the property {{petals.environment.config.file}}.
The default environment configuration comes with options to enable the SNMP agent of the JVM. Just uncomment them to enable it. This default SNMP configuration requires an ACL file. An ACL file is also provided by default.
{note}*Caution*: For a Debian-based installation, this default SNMP configuration can be used only by the system user '{{petals}}' because of the security required on the ACL file.{note}
{note}*Caution*: The environment variable JAVA_OPTS will always take precedence over the value present in {{$PETALS_HOME/conf/env.sh}} or {{/etc/petals-esb/default-env.sh}}. Nevertheless, both will be used.{note}
{anchor:ContainerConfig}
h1. Container configuration reference
The container configuration is located into the file {{server.properties}} and expressed as property (key/value).
A property value can be set using the value of another property as a variable using a placeholder mechanism, and you can add your own properties:
{code}
myserver.host=localhost
petals.topology.url=http://${myserver.host}/petals/${petals.container.name}/topology.xml
{code}
{note}
The property {{petals.environment.config.file}} does not accept placeholder.

Configuration file of the environment running the Petals container. This configuration file is used to set JVM options. A relative file is accepted only for local container configuration URL (file://...), otherwise it must be an absolute path. For ZIP archive based installation, just update directly the file {{$PETALS_HOME/conf/env.sh}}. |
