Migrate from web container mode to standalone mode

An IG .war file isn’t created or delivered from IG 2024.3. Consider these points when migrating from a .war delivery to a .zip delivery.

Session replication between IG instances

High-availability of sessions isn’t supported by IG in the .zip delivery.

Streaming asynchronous responses and events

In ClientHandler and ReverseProxyHandler, use only the default mode of asyncBehavior:non_streaming; responses are processed when the entity content is entirely available.

If the property is set to streaming, the setting is ignored.

Connection reuse when client certificates are used for authentication

In ClientHandler and ReverseProxyHandler, use only the default mode of stateTrackingEnabled:true; when a client certificate is used for authentication, connections can’t be reused.

If the property is set to false, the setting is ignored.

Replacement settings for migration from web container mode with Tomcat

Feature Setting for web container mode with Tomcat Replacement setting

Feature	Setting for web container mode with Tomcat	Replacement setting
Port number	Configure in the `Connector` element of `/path/to/tomcat/conf/server.xml`: `<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />`	Configure the `connectors` property of admin.json.
HTTPS server-side configuration	Create a keystore, and set up the SSL port in the `Connector` element of `/path/to/tomcat/conf/server.xml`.	Create a keystore, set up secrets, and configure secrets stores, ports, and ServerTlsOptions in admin.json. For information, refer to Configure IG for HTTPS (server-side).
Session cookie name	Configure `WEB-INF/web.xml` when you unpack the IG .war file.	Configure the `session` property of admin.json.
Access logs	Configure with `AccessLogValve`.	Configure in the Audit framework. For information, refer to Audit the deployment and Audit framework.
JDBC datasource	Configure in the `GlobalNamingResources` element of `/path/to/tomcat/conf/server.xml`.	Configure with the JdbcDataSource object. For information, refer to JdbcDataSource. For an example, refer to Password replay from a database.
Environment variables	Configure in `/path/to/tomcat/bin/setenv.sh`.	Configure in `$HOME/.openig/bin/env.sh`, where `$HOME/.openig` is the instance directory.
Jar files	Add to to web container classpath; for example `/path/to/tomcat/webapps/ROOT/WEB-INF/lib`.	Add to `$HOME/.openig/extra`, where `$HOME/.openig` is the instance directory.
