[jboss-user] [JBossCache] - Re: tx completion STATUS_UNKNOWN

Guy Pardon of Atomikos justifies his use of "UNKNOWN" saying: anonymous wrote : | I think the status cannot be determined for the following reason. Imagine transaction A started in a remote VM and imported in the local VM subsequently. Also, suppose the local VM only does READ_ONLY work. | | Then, image two-phase commit: | | case 1: | -transaction A prepares | -the local VM returns READ_ONLY for all its work | -transaction A commits | | case 2: | -transaction A prepares | -the local VM returns READ_ONLY | -transaction A rolls back | | Both cases are indistinguishable by the semantics of the READ_ONLY on prepare: no further outcome is desired. | | IMHO, therefore the only state that makes sense is UNKNOWN. It would be a mistake to say COMMITTED, and likewise for ROLLEDBACK. | | Guy | Guy has later said that perhaps he could use "NO TRANSACTION" in such a situation as well, however, it appears the JBossCache 1.4.x code will behave the same for NO_TRANSACTION as it does for "UNKNOWN".
