Hi,
Some Hypersonic problems in JBoss 2.2.1 out of the box that have been
causing me trouble for a few weeks... I wonder if anyone can help me
with them?
1) As I go on doing operations with CMPs (with lots of large
Serializable objects or byte[] in the entity beans in question, in case
that makes a difference) the
JBoss-2.2.1_Tomcat-3.2.1/jboss/db/hypersonic/default.script file grows
and grows, even if for example, I drop the tables. The default.data
file never grows. How can I get the `log' flushed? Here, for example,
id the current state of the hypersonic directory after inserting the
same few MB of data a few times:
drwxr-x--- 2 dhd ExNet 512 May 14 00:24 ./
drwxr----- 5 dhd ExNet 512 May 10 22:51 ../
-rw-r----- 1 dhd ExNet 12 May 14 00:24 default.backup
-rw-r----- 1 dhd ExNet 20 May 14 00:24 default.data
-rw-r----- 1 dhd ExNet 80 May 14 00:24 default.properties
-rw-r----- 1 dhd ExNet 125300428 May 15 18:46 default.script
2) I cannot create records (entity beans), eg including largish
Serializable objects or byte[]s, larger than about 32kBytes in total.
Is there any way to fix that directly? At the moment I am fragmenting
data across several entity beans, but that will make some things that I
want to do, such as maintaining a live index in an object in a entity
bean, usually held in memory but passivatable back to the db,
spectacularly inefficient.
3) Even if I keep records shorter than 32kBytes, if I undeploy and
redeploy the same (unchanged) EAR, on trying to read some entity beans
back into memory, they are reported as corrupt, `not containing
serializable data' in some ByteArray deserialisation routine inside
Hypersonic itself I think. This means I usually have to reload lots of
data each time I make even the most minor change to my EAR, which is
very sad. All data is loaded through Java with no access by anyone
else.
4) I intend to have several GB of data in my database in the end, with
several tables/beans having up to millions of records each. Will that
completely stuff Hypersonic?
I am resigned to having to sort some of these problems by moving to a
different DB, but I want at least to understand what's going on with
Hypersonic and make it a little more robust and to last as long as
possible.
Regards,
Damon
