Connection error: "object reference not set to an instance of an object." -
Descrição
Customer had DB2 client v 8.2 installed before Toad for DB2.
After install Toad he tried to connect to database and got error: "object reference not set to an instance of an object." -
Causa
Normally, Toad forDB2 2.5 will install DB2 client 9.1 at the same time with Toad installation.
DB2 v 9 override db2 v 8.2 client. -
Resolução
Please removed the db2 version 9 client. Seems like there was an overlap with the 8.2 client.
