there is a set of stuff needed to boot stored as properties. Things like the id of table with the table info, table with the attribute info, ... , maybe it is there. should be a file either in top level or in seg0 i think.

In the context of DERBY-6890, I've been trying to understand a little bit more about how and where the 'collation=' and 'territory=' information from the JDBC Connection URL is stored within the database at database creation time. I could use some advice from anyone who has a deeper understanding of how Derby handles database collection/territory configuration. I'm not sure if this is written up anywhere, other than at https://db.apache.org/derby/docs/10.12/devguide/cdevcollation.html I tried poking about in the system tables, but there wasn't anything in SYSTABLES or SYSCOLUMNS that seemed to say anything about collation or territory information. Which makes sense, I think, because AIUI this information isn't specified on a table-by-table basis; it's specified once, and applies database-wide. So I'd like to find where that information is stored, and how the engine picks it up, and passes it down to places like the "collation_ids" array in impl.store.access.btree.Btree. Can anyone point me in the right direction? thanks, bryan
