The solutions to the following situations might help you with high availability.
I am not sure where to look for status information regarding client connections to the PowerCenter repository.
In PowerCenter Client applications such as the PowerCenter Designer and the PowerCenter Workflow Manager, an error message appears if the connection cannot be established during the timeout period. Detailed information about the connection failure appears in the Output window. If you are using
pmrep
, the connection error information appears at the command line. If the PowerCenter Integration Service cannot establish a connection to the repository, the error appears in the PowerCenter Integration Service log, the workflow log, and the session log.
I entered the wrong connection string for an Oracle database. Now I cannot enable the PowerCenter Repository Service even though I edited the PowerCenter Repository Service properties to use the right connection string.
You need to wait for the database resilience timeout to expire before you can enable the PowerCenter Repository Service with the updated connection string.
I have the high availability option, but my FTP server is not resilient when the network connection fails.
The FTP server is an external system. To achieve high availability for FTP transmissions, you must use a highly available FTP server. For example, Microsoft IIS 6.0 does not natively support the restart of file uploads or file downloads. File restarts must be managed by the client connecting to the IIS server. If the transfer of a file to or from the IIS 6.0 server is interrupted and then reestablished within the client resilience timeout period, the transfer does not necessarily continue as expected. If the write process is more than half complete, the target file may be rejected.
I have the high availability option, but the Informatica domain is not resilient when machines are connected through a network switch.
If you are using a network switch to connect machines in the domain, use the auto-select option for the switch.
