Conversation ID Length
- Jim Wilson
Owned by Jim Wilson
Background
NEXUSe2e versions X.Y and earlier supported Conversation ID lengths up to 96 characters. At least one NEXUSe2e user has reported interoperability issues as a result of receiving messages with Conversation IDs longer than 96 characters. The issue is correctable in NEXUSe2e versions X.Y and earlier and is not an issue in versions X.Z and later.
Outstanding Questions
- Is the "new' NEXUSe2e compatible with the "old" version?
- What length is the conversation ID generated by the "new" NEXUSe2e?
- What versions specifically are we referring to we say "old" and "new"?
Issue Work-Around for NEXUSe2e Version X.Y and Earlier
The maximum length for conversation and message IDs is 96 characters NEXUSe2e versions X.Y and earlier. To overcome this limitation, increase the field length directly in your DBMS with an SQL statement:
ALTER TABLE nx_message MODIFY message_id varchar(256) ALTER TABLE nx_conversation MODIFY conversation_id varchar(256)
The configuration within NEXUSe2e that creates the schema cannot be changed easily, but once the length constraint is changed, NEXUSe2e will not reset it to the configured value.
