How the PeopleSoft Integration Gateway connectors are loaded, and where the connector information is stored?

By -
The following is what happens when a user requests to loads connectors of an Integration Broker gateway:

1. On the Integration Broker Gateways page the user presses the Load Connectors button and PIA ICPanel servlet passes that request via Jolt connection to the local application server.
2. The app server generates a special internal service operation, with external operation name "gatewayservicerequest", connector class name TargetIntrospection, and no message body.
3. The app server issues an http post of the service operation request to the local Integration Gateway listening connector.
4. If a remote gateway's connectors are being loaded, the local gateway forwards the request to the remote one.
5. The target Integration Gateway invokes the Introspection service to load all the connector properties, this is, it calls the TargetConnector.introspectConnector() method and navigates through the returned ConnectorDataCollection object to gather the data.
6. If a remote gateway's connectors are being loaded, the information is brought back from the remote gateway to the local gateway.
7. The local gateway sends the configuration information to the local (issuing) app server.
8. The app server stores the configuration information into tables PSCONN and PSCONNPROP
PSCONN fields: CONNGATEWAYID, CONNID, CONNCLASSNAME, DESCR, STATUS
PSCONNPROP fields: CONNGATEWAYID, CONNID, PROPID, PROPNAME, SEQNUM, PROPVALUE, DATATYPEDESCR, REQUIRED_FLG, DEFAULT_FLG, DESCRLONG
9. The app server returns to PIA ICPanel servlet the data to update the Integration Broker Gateways page.

Transferring a file using SFTP to specified target location: (Thanks to Jawahar who helped me in this article) A lot has been mentioned about sFTP support in PT 8.51. Below gives clear idea on SFTP. Are there any specific pre-requirements for using file transfer protocols? Yes. Though FTP can be used directly by giving the URL as a string to the peoplecode method, other protocols (ftps, sftp, http and https) require the URL to be passed as a URL identifier only. When an URL identifier is created, URL properties link on the page gets enabled. Users need to provide the URL properties specific to the protocol they are using on this "URL properties" page. The URL properties differ based on the protocol choosen. Once URL Identifier is ready, it can be used in any of the file attachment peoplecode methods just like the existing way.   What are the authentication methods supported for sftp? Password and Public Key authentication are supported.

Peoplesoft Error: All Processing Suspended: Restart OPRID=PS, RUNID=RUN01, PI=5000(108,503)

By mymithraa -
All Processing Suspended: Restart OPRID=PS, RUNID=RUN01, PI=5000(108,503) What is this about and what should be done? This error can occur when Application Engine programs are restartable and run via the Process Scheduler, and the last run was No Success - And an attempt re-run, rather than re-start will produce error as well The cause of this message is that previously this same AE program was run using the same OPRID=PS & RUNID=RUN01. It was not Successful on initial run, and now an attempt to RUN the same program has occurred, instead of an attempt to RESTART the original that failed. Whether this error Happened in Development??? This message happened while the Customer was in Development phase of this AE program. It could have happened when this AE was in Production as well. However, what to do would have completely different emphasis depending on if this happens in Development or Productions. During the development cycle, we would expect that this AE would have to run many tim
