Configuring asynchronous services

The AsyncService translator independently processes asynchronous requests constructed by the Teamcenter server using Teamcenter SOA native C++ framework in the background mode. Background operations are accomplished by using Dispatcher to hold and schedule the asynchronous request and to initiate the operation as a standard services oriented architecture (SOA) request in a separate Teamcenter four-tier session. Operations are executed using the Teamcenter middle tier for session management and load balancing. The operation can be executed either on the local site or on a remote site. When running the operation on a remote site, the asynchronous facility uses the same configuration and authentication information in the site object as used by Teamcenter Multi-Site. If the site uses Teamcenter Security Services single sign-on (SSO), the asynchronous facility uses SSO tokens to authenticate to the remote site. After the request is completed, the Teamcenter event or notification, or subscription service is used to inform the user that the background task is complete. The asynchronous session is initiated in a new session as the same user, group, or role and locale as the original session. Authentication without Security Services The original Teamcenter server session generates a unique authentication token for the user, encrypts it, and stores it with the background request. When the request is executed, this token is decrypted and used in place of a password to authenticate the user’s session. Remote invocation The asynchronous facility can execute the operation on a remote site if the installation is configured for Multi-Site.
