How to modify the length of the issue type name more than 60 characters(MS SQL)

[Roy Lee]

Data Base use MS SQL Server 2015

The length of the issue type name must not exceed 60 characters,but I have system design requirements that need the length of the issue type name more than 120

[Gregory Van Den Ham]

I have not seen this be able to be done.  If it was possible, it might be editing source code, but then your version upgrade path is shot.

I'd say you want to review the design requirements you've been given.

Rewrite the whole of Jira and all its add-ons.

The limit is not coded in many places, so it would not be that hard to find and amend the code that stops people entering it, but you are going to need to check every place where it might be used for assumptions, both  the code that reads it and how a longer field will affect the UI

I would talk to the people who have given you broken requirements.  There's a clue in the name of the field - "summary".  It should be short and give the reader a rough idea.  Many people would argue that 60 characters is too long, not too short.  You should be telling the people with this "requirement" that they are wrong.
