我有一个我继承的遗留VB6应用程序。我遇到的问题是我变得臭名昭着
ORA-12638: Credential retrieval Failed
当它尝试连接到我们的一个Oracle数据库时出现错误消息。但是，我可以从sqlPlus和Toad连接好。我已经Googled，每个人似乎都说修改他们的sqlnet.ora文件
sqlNET.AUTHENTICATION_SERVICES=(NONE)
做了诀窍我还没有找到有替代方案的人。这是我的连接字符串的样子：
"PROVIDER=OraOLEDB.Oracle;DATA SOURCE=(DESCRIPTION = " & _ "(ADDRESS = (PROTOCOL = TCP)(HOST = server1) (PORT = 1521))" & _ "(ADDRESS = (PROTOCOL = TCP)(HOST = server2) (PORT = 1521))" & _ "(LOAD_BALANCE = yes) " & _ "(CONNECT_DATA = " & _ "(SERVER = DEDICATED) " & _ "(SERVICE_NAME = database_name_here) " & _ ") " & _ "); " & _ "User Id=username_here;Password=password_here;"
对于我的VB代码，这很简单。
Private oracleDatabaseConnection As ADODB.Connection Set oracleDatabaseConnection = New ADODB.Connection oracleDatabaseConnection.Open oracleConnectionString
任何人都有什么想法？
