Resolution:
Occassionally, the TIB/Administrator will not successfully deploy BusinessConnect, and exceptions may be seen in the deployment log looking like this:
006 Oct 10 08:40:10:215 GMT -7 Error [ApplicationConfiguration] AESDKJ-0000 [HttpProcessor[18082][4]] com.tibco.objectrepo.OperationFailedException: Error retrieving stream for VFile OnStartup.process URI=

Underlying cause:
java.io.FileNotFoundException: /tmp/tibco_BCDEV_Administrator_tdbw02.ssg.petsmart.comachive1160097400813/Gateway/Shared/Startup-Shutdown/OnStartup.process (A file or directory in the path name does not exist.)

This occurs if the /tmp directory (where the archive is first built before deployment) is tampered with by another process, or if the /tmp directory is full.  To correct this issue,

1.  Stop the Administrator
2.  Delete the archive directories that corresponde with the domain/BC name.
3.  Restart the Administrator
4.  Try to deploy again.
