I do not see that happening in the short term. PASE is an environment, hence the E in PASE. Firing up an environment every time to access a DB2 function can't be good for performance. But are you saying that IBM is using PASE to transition us from i5/os to Linux or AIX? I sometimes wonder myself. New applications that get a lot of push from IBM are primarily written in PASE, like IP Telephony and PHP. I feel that doing the additional work, and moving them to truly native, like Domino, makes a far superior product. Converting from native to PASE however is merely a preparatory step to abandoning i5/OS altogether, like IBM did with Tivoli Storage Manager. If IBM did convert DB2 to run under PASE I would feel that would be the LAST release of i5/OS.
It is kind of tricky. It does not make sense to keep DB2 out of PASE for performance reasons ( of the PASE apps ) and duplication of effort by IBM. DB2 for AIX has XML support and is probably more feature rich in other ways than DB2 for i5/OS. A vendor with a software package written to use Java and DB2 on AIX might not be able to port to i5 only because i5 DB2 does not support XML. But you cant have a database in PASE and another native ( as a transition ) because of the confusion of having two copies of a table, and performance problems what with native code accessing the PASE database table. -Steve
