Chris Wolf commented on HBX-812:
--------------------------------
I have the problem, it takes 10-20 MINUTES for the metadata query to complete,
the same thing happens with middlegen.
DB: Sybase ASE-12.5.3
Eclipse: 3.2
Hibernate tools: 3.2.0-beta9a
I tried jConnect-5.5.6 and jTDS-1.2. jTDS was faster, but did not return
all the tables. I also had to configure autocommit=true.
Granted, there are 2700 tables in this database, however this is the reality in a large
institutional environment with lots of legacy database objects. I had
the tables filter configured to select only three tables, and that still did
not improve the metadata query time.
This is pretty much a show-stopper for me to use tools or middlegen.

Key: HBX-812
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HBX-812
Project: Hibernate Tools
Type: Bug
Components: reverse-engineer
Versions: 3.2beta8
Environment: MySQL 5.0, Eclipse 3.2, JDK 1.5, Beta8 for Hibernate Tools
Reporter: Syd Poetry
I just updated a bunch of components for Eclipse (mostly related to Visual Editor); added
a couple of tables to my database, went to regenerate all the POJO clases .hbm.xml mapping
files, and found that anything that queries the database schema runs abysmally slow.
Updated the tools from beta6 to beta8 thinking it might be a conflict with one of the
updates that was performed, still very slow (5+ minutes to retrieve a list of tables!).
Deleted all my hibernate-related XML files thinking it might be a parsing error, went to
generate a new console file, and revenge.xml, found out that any listbox that tried to
access the schema appeared to be hanging. It finishes after much hard-drive crunching. I
have 2.2 GBs free running windows XP, MEM usage is 856 MB out of 1.5 GB physical memory.
Just out of curiousity, is *anyone* else having this slow response for schema detection?
I'm wondering if I have to update another component like a driver or something like
that.
