Inherits from: EOAdaptorContext : NSObject
An OracleContext represents a single transaction scope on the database server to which its adaptor object is connected. If the server supports multiple concurrent transaction sessions, the adaptor may have several adaptor contexts. An OracleContext may in turn have several OracleChannels, which handle actual access to the data on the server.

OracleChannel sends this message to OracleContext when it (OracleChannel)
has just closed a channel to the server.
