They say "When using SQL Relay, > the database can be bounced without having to restart Zope" I tried this. It works, but possible problem with volatile attributes persists - it is specific to Zope Database Adapters, and SQLRelay adapter uses '_v_' attributes too. Issue with 'reconnect' behaviour of SQLRelay may be that your Zope instance will appear 'hanged' when database is not running (or something like that) because Zope threads will be waiting for DB response. AFAIR there is no timeout for SQLRelay (sometimes it is good, sometimes not). Another question is what happens with transactions integrity in this situation. -- Maciej Wisniowski _______________________________________________ Zope-DB mailing list Zope-DB [at] zope http://mail.zope.org/mailman/listinfo/zope-db
