The set of properties supported by jTDS is:. If you can’t figure out why, ask your network administrator for help. As a conclusion, when executing stored procedures that only return update counts output parameters will be available immediately, as jTDS will process and cache the whole response. Have you got any figures to prove that? However, you can run any of the benchmarks yourself, the effort is minimal.

As a general principle we try and keep synchronization to a minimum both for performance and deadlock reasons. If you have sybaae not to store the driver in the SuperCHANNEL drivers directory then you will need to specify the full path to the driver location instead.
This gives jTDS a 2x performance increase over the next jds driver in some not so uncommon cases. I’m trying to connect to SQL Server 6.
Sybase JDBC Driver and URL Information
We will make the sybasd changes. This is caused by triggers; replication is also implemented through triggers, so you will encounter this issue on replicated databases too.
Memory usage keeps increasing when using generated PreparedStatements. This is common if say you are querying a stored procedure that creates a temp table, runs updates against it and then returns the table as a result set.
java – Sybase db connection using jtds driver getting failed with no response – Stack Overflow
To use SNU with this source, the -classpath setting must include the location of your driver. Stored procedures should jtxs invoked using the special JDBC call escape syntax.
If you are prompted to provide administrator permissions, click Continue. If you encountered an issue that you have tested and retested and you’re sure it’s a bug, use the Bugs link on top of the page. In case you are wondering if this is right, this is a quote from the CallableStatement API documentation: The default install does not configure the SQL Browser service to start automatically so you must do it manually. As a conclusion the only safe multithreading scenarios are these: As i said earlier i have opened a tunnel in my local machine to the remote db and trying to connect using the tunnel.
If you need help with any other jTDS-related issue, search the Help forum first and if you still don’t find jtss, post a question. You will have to use the instance property either append it to the URL or place it into the Properties you supply to getConnection instead of doing it the Microsoft way.
The JNetDirect license precludes publication of performance test results. Driver class, which means that jtds. The client may be suspended if the system log fills so check that the log space is sufficient for the batch you are trying to load.
Features such as generated keys retrieval, named stored procedure parameters, and save points are also implemented. If you chose the default installation options, the location will be: Depending on your system configuration, you may need administrator permissions to copy to this directory. Because there is no URL when using the JtdsDataSource there are three other properties with setters and getters to take the place of those items that are part of the URL’s syntax: This is what happens with SQL Server-returned errors and warnings and is consistent with how other drivers handle exceptions.
This parameter is lastUpdateCount and you can find out more about it here. Where does one place an instance name in the connect string?
As a sidenote, The Microsoft driver and probably the others, too “optimize” this behavior by skipping over the update count, which is wrong according to the JDBC spec. Actually we do have benchmark results from two different benchmarks, both developed by large commercial SQL Server JDBC driver vendors to demonstrate the performance of their own drivers.
Locate the line that defines the Sybasr class path property java. Why do I still need to provide a username and password?
