DB2 .NET Data Provider no longer able to connect.
-------------------------------------------------
Key: DERBY-5551
URL: https://issues.apache.org/jira/browse/DERBY-5551
Project: Derby
Issue Type: Bug
Components: Network Server
Affects Versions: 10.8.2.2, 10.8.1.2
Environment: Network Server running on any platform (Tested on Windows
2003 Server and Fedora 14 Linux) using IBM JRE (1.6.0 SR9)
DB2 .NET Data Provider running on Windows 2003 Server
Reporter: Ben Hardill
While looking for a solution for connecting a .NET C# application to a Derby
database I tried the DB2 .NET Data Provider. I thought this might work since
both DB2 and Derby both use DRDA and that the DB2 JDBC driver will happily
connect to Derby as well.
I had 2 different Derby instances that I used to test this and one worked just
fine and the other would fail to connect with the following error:
ERROR [58004] [IBM] SQL0901N The SQL statement failed because of a non-severe
system error. Subsequent SQL statements can be processed. (Reason "DRDA AR:
Parser Invalid Value".) SQLSTATE=58004
Investigation showed that the failing instance was using the latest Derby
version (10.8.2.2) and the working version was using an older build (10.6.1.0).
Trying the release versions in order shows that the regression happens with the
release builds 10.8.1.2 and later.
The DB2 .NET Data Provider can be downloaded here:
http://www-01.ibm.com/software/data/db2/ad/dotnet.html
A quick sample app can be found here:
http://www.hardill.me.uk/Derby.NET-Test.zip
You can run it as follows:
TestDB2Connection.exe -host 192.168.229.1 -port 1547 -database IPA -user user
-password foo -query "select * from APP.PERSONS"
It outputs a CSV dump of the result set
