RE: Problems starting ozone ?

Hi Falko,
I tried to recompile the whole but ...
I get the following error:
D:\Programs\ozone-0.5.5\org\ozoneDB\core\wizardStore\WizardStore.java:55:
Wrong
number of arguments in constructor.
        idTable = new DxDiskHashMap (env.dir + "ostab" + File.separator +
"tab",
 idTableBufferSize, idTableCacheSize, idTableSubtableSize);
                  ^
1 error

I downloaded the last release in cvs (it report 5 days ago), but I've the
same error.

I'm using the web interface to your cvs, and there is a problem also in
download :

"The requested URL
/cgi-bin/cvsweb.cgi/~checkout~/ozone/org/ozoneDB/DxLib/DxDiskHashMap.java
was not found on this server. "


Bye
Mario

Yes, this is OK.

The ostab dir contains the object ID table. ozone uses a DxDiskHashtable,
which
in fact is a B-tree, for this. The sub-tables of the B-tree have 255 entries
(8bit). Therefore there are many small files.

BTW: There is a new version of the DiskHashtable in CVS that supports
adjustable
sub-table sizes. The CVS version of ozone uses now 11/10 bit sub-tables,
which
reduces the number of files by a factor of 6. Besides, the new DiskHashtable
compresses sub-tables before storing on disk, which reduces the size of the
ostab dir by a factor of 6. ;)

Anyway, your ostab version produces many small files. This is ok. This
should
not cause the problems you reported.

I've checked in a new version of
org/ozoneDB/core/wizardStore/WizardStore.java
that displays not only the "no valid id table found" message but also the
exception that was thrown. Please compile CVS version (or use attached file
in
your 0.5.5 source tree) and start server with option -debug and send the
server
output.
