Or in other words can a transactions span multiple env's?
No. But a single env can contain multiple DBs, and a txn can span multiple DBs within the same env:
Create Env Create DB - staff Create DB - payroll mdb_txn_begin(env, NULL /*parent*/, &txn_staff) - 1st write txn insert staff data mdb_txn_begin(env, txn_staff /*parent*/, &txn_payroll) insert payroll data mdb_txn_commit(txn_payroll) mdb_txn_commit(txn_staff) -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
