Does anyone out there know how ORACLE actually works in a cluster? I am very interested in finding out the following: 1) Does Oracle use the distributed lock manager? 2) Can more than one node in a cluster have the database open? If no, does ORACLE use in intelligent server to support access to the data from other nodes in the net? Or does each process accessing the data create a FAL-like process on the node serving the database? I am asking these questions to understand why ORACLE is supposed to be so bad in a cluster. This information (I have other facts regarding DBA activities, etc) would help in competing against them in a large local account. Any help would be appreciated! Arthur Kamp - SWS London, Ontario

Oracle V6 works on only one node in a VAXcluster system. It as yet
has NO VAXcluster support.
No version of Oracle has ever supported the Distributed Lock Manager.
I do not know how other nodes access the Oracle database node. My
guess would be that the mechanism is the same used by Sybase, Adabas,
and every relational database other than Rdb.
Also, beware that Oracle is getting famous at giving reference sites
that are "very happy VAXcluster Oracle users." The reality is that
almost all of these "VAXcluster reference sites" use Oracle on only
one node. There are almost no Oracle sites that have the database
active simultaneously on more than one VAXcluster node. If they
give a reference site, it's worth the time to be certain your account
qualifies the reference (preferably when he calls to talk to the
reference). It can be very unpleasantly embarrassing for the big
"O".
