[Slobodan Vujasinovic <slobodan@xxxxxxxxxxxxx>]

Hi all,

Enhydra DODS 7.0-4 is just released!

CVS sources are updated and binary distributions are available from:
http://forge.objectweb.org/project/showfiles.php?group_id=61

Changes:

- Added new parameters for cache initialization:
• synchLoadRowCountLimit - max number of rows in the table for which the 
synchronous cache load is performed if defined by configuration. If the 
number of rows is greater, the table's cache will be loaded asynchronous 
and this number will be taken for the asynchLoadPriority. The default 
value is 0 and means that asynch cache load is not performed if 
configuration parameters for asynch cache load are not defined.
• maxExecuteTimeCacheInit - max time for which the query is not printed 
in application's log file durung the cache initialization. If the time 
is greater, query (SQL statement, execution time and maxExecutionTime) 
is printed. Value 0 means that nothing is printed.
• queryTimeoutCacheInit - max number of seconds for which the query for 
cache initialization should be executed. If the limit is exceeded, an 
exception is thrown. Value 0 means that there is no limit.
• queryTimeLimitCacheInit - max number of milliseconds for which the 
query for cache initialization should be executed and the resulset read 
from ResultSet. If the limit is exceeded, an Exception is thrown. Value 
0 means that there is no limit.

- Added new parameter simpleCacheRowCountLimit - max number of rows in 
the table for which simple cache is still used. If the table has more 
rows than defined by this parameter, complex cache is used for simple 
queries. The default value is 0 (simple cache is used for all simple 
queries).

- Added new method in the 
com.lutris.appserver.server.sql.StandardDatabaseManager class:
public void asynchInitCaches(int threadNum)
for postponed cache initialization.

- Added patches in query cache mechanism for queries with database 
limit. Query results that contained less result than databaseLimit were 
retrieved from the database instead from the cache. Now, they are 
retrieved from the cache.

- Apache Ant upgraded to version 1.6.5, consequently some scripts are 
updated too.

- JTA example switched to use LocalContextFactory.

- Added <UseTopSyntax> tag in <dbVendorConf>.xml file. If set to true, 
DODS generates "TOP" keyword in SQL statement with value defined by 
maxDBrows attribute of Query object. With "TOP" keyword is defined 
maximum numbers of rows that can be retrieved from database (patch for 
Microsoft SQL Server 2005).

- Added patches in query cache mechanism for queries that contain 
security constraints and use database limit. Query results that had 
execly the same number of results as databaseLimit were retrieved from 
the database instead from the cache. Now, they are retrieved from the cache.

- Added logs for synchronous cache initialization.

- Patches to prevent exhausting connection pool, thanks to Joao Paulo 
Ribeiro.

- Applied patches for DB vendor-independent read/write of BLOBs in 
OracleDriverDependences, thanks to Monique Maker.

- Adding support for STATISTICS create statements depending on parameter 
in dbVendor conf file: EnableCreateStatistics (for Microsoft SQL Server 
2005).

- Added support for statistics element in doml for create statistics 
statements

- Added support for includeIndexColumn in index as index extension. 
Adding support for INCLUDE in CREATE INDEX statement depending on 
parameter in dbVendor conf file: IncludeIndexColumns
