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. You can control the real batch size using the batchSize parameter; setting it to a non-zero value will break up batches into smaller pieces on execution, hopefully avoiding the problem. Jon Skeet k Other I didn’t find the answer to my problem in this FAQ. When executing large batches on Sybase the client application may hang or the response time may vary considerably. Have you got any figures to prove that?

Check out the jTDS feature matrix for more details.

Memory Usage Memory usage keeps increasing when using generated PreparedStatements. In this case it’s the net. Microsoft’s driver inatall actively maintained, where jTDS hasn’t been updated since and prior to the small round of updates done in it hadn’t been updated for multiple years.

A common solution rather than the inelegant execute and then cycling through multiple result sets, is to supress the update counts for statements you are uninterested in. In order to change that you have to specify it explicitly in the Properties or the URL you supply when you create the connection. Sign up using Facebook. Related content No related content found. When executing large batches on Sybase the client application may hang or the response time may vary considerably. Stored procedures should be invoked using the special JDBC call escape syntax.

In our oppinion this is better than having a benchmark of our own, which could be designed in such a way as to give jTDS the edge.

Why do column names more than 30 characters long, get chopped off at 30 characters? 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. For insall that return multiple results the JDBC spec requires execute to be used.

There is a good side to this: This is caused by triggers; replication is also implemented through triggers, so you will encounter this issue on replicated databases too. Actually we do have benchmark results from two different benchmarks, both developed by large commercial SQL Server JDBC driver hdbc to demonstrate the performance of their own drivers. Temporary stored procedures are created for each unique SQL statement and parameter combination faster.

Properties can be passed to jTDS in one of three ways: Because there is no URL when using the JtdsDataSource there are three other properties with setters and getters to take the place of jrbc items that are part of the URL’s syntax: ClassNotFoundError is thrown by the classloader when it can not find a certain class. The existing configuration should look similar to jtdw The set of properties supported by jTDS is:.

The command line you posted doesn’t work. Or even better, a benchmark I can run myself? What do i have to do to connect to Netcool Omnibus or any derived Product. As a general principle we try and instalp synchronization to a minimum both for performance and deadlock reasons.

What should I do? So for procedures returning ResultSet s you will have to loop, consuming all results before reading the output parameters i.

Also, please take a look at our ResultSet support page for some additional information and tips. You are very probably using TDS 4.

JTDS Driver

So, for maximum compatibility, it is recommended that you use execute anytime you run queries returning more than one result even if the particular driver you are using jdnc you to do otherwise. If you can’t figure out why, ask your network administrator for help.

The name of the jTDS jar file may be jtds Here are the results of the i-net test: 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.

You need to put.
