Donan

You have to use the RmiJdbc driver to access InstantDB from multiple virtual
machines.

Have a look at
http://instantdb.enhydra.org/software/documentation/warnings.html for an
explanation of what's going on here.

Subject: InstantDB: Concurrent access and database integrity


>Greetings,
>
>I'm in the process of evaluating InstantDB and have downloaded and
>tried out both versions, 3.13 and 3.14 beta. Using the sampe.prp
>as my database and a modified version of commsql.java found in
>Examples, I created a table called temp as follows:
>
>    create table temp (name varchar(32))
>
>From here, I started two commsql sessions and carried out the following
>sequence:
>
>1. commsql session 1: <select * from temp>    no records found
>
>2. commsql session 2: <insert into temp values ('joe')>
>
>3. commsql session 2: <commit>
>
>4. commsql session 2: <select * from temp>    the record 'joe' was
>returned
>
>5. commsql session 1: <select * from temp>    no records found
>
>So my question is "Are there parameters I should be configuring to
>enable databas integrity, or is it the case that InstantDB is unable to
>handle concurrent update from different sessions??"
>
>Thanks!
