    Some info on Tyrex

    kubo kushi Newbie

      Can someone explain the importance of Tyrex ? In other words:
      Do I necessarily need it for 2 phase commit ?
      Does it run only on JVMs or does it manage non-java transactions (mixed with say, C/C++)?
      If I have a Client/Server (written in C) application and want to have my JBoss application to participate in the same transaction, will Tyrex do the trick ?

      Thanks in advance

          That depends on how much recovery ability you want. The default jboss tm will do 2pc involving exactly one jboss server, however since it does not do transaction logging it cannot recover from crashes. It also cannot participate in distributed (i.e. multi-tm) transactions.

          I believe it is written in java but communicates using corba. It may interoperate with non-java corba tms, I don't know.

          I think you would at least need a C Corba tm.

          I am not very knowledgeable about tyrex, so you might consult its documentation if no one else answers.
