Troubleshooting
Problem
When trying to connect to a DB2® type 2 datasource from WebSphere® Application Server error java.lang.UnsatisfiedLinkError: SQLConnect occurs.
Symptom
A type 2 driver has a native library that must be loaded by the jvm process. A java.lang.UnsatisfiedLinkError means that the WebSphere Application Server jvm process could not find or could not load the DB2 library.
The following java stack is typical of an UnsatisfiedLinkError using the DB2 legacy driver
| java.lang.UnsatisfiedLinkError: COM/ibm/db2/jdbc/app/DB2Connection.SQLConnect(Ljava/lang/String;II)I at COM.ibm.db2.jdbc.app.DB2Connection.connect(Unknown Source) at COM.ibm.db2.jdbc.app.DB2Connection.<init>(Unknown Source) at COM.ibm.db2.jdbc.app.DB2ReusableConnection.<init>(Unknown Source) at COM.ibm.db2.jdbc.DB2PooledConnection.getConnection(Unknown Source) at com.ibm.ws.rsadapter.spi.WSRdbDataSource.getConnection(WSRdbDataSource.j ava:1768) The DB2 legacy driver uses these two files

The DB2 universal (UDB) driver uses these two files
- db2jcc.jar -- this is the file that contains the java portion of the driver
- libdb2jcct2.a|so or db2jcct2.dll -- this is the native library for the DB2 universal driver.
