Remote servers that are “DTM-enabled” support the full two-phase commit service enabled by ASTC. Servers that support this must allow a separate connection (or session) to either commit or roll back a transaction that was begun by another session. This capability is necessary if the commit coordinator (ASTC) is required to connect to a remote site and commit or roll back in-doubt transactions. Adaptive Server 12.0 and later provide this support, as does DirectConnect for Oracle 12.5 or later.
