The Portal Runtime Container (PRT) provides a Java-based framework for running portal applications, which produce content for display in the portal.
The PRT is delivered in the in EP-BASIS-API package and includes the following parts:
tc~epbc~prtc~basis: a Java EE library containing the JNDI, Registry and Concurrency APIs
tc~epbc~prtc~api: a Java EE library containing the PRT APIs
tc~epbc~prtc~core: a Java EE service containing the PRT APIs implementation as a Web container extension
The PRT provides the following Java EE services:
com.sap.portal.prt.sapj2e: manages the deployment of content archives, such as .epa or .pga
prtbridge: provides a link between portal runtime processes and the Java EE engine cluster configuration and communication. It is installed as a Java EE engine service.
You can configure the PRT to fine-tune its performance.
