    Unanswered: ODBC connection to DB2 need 55 sec

    this is my first post in this forum..
    I have a problem with a ODBC connection.

    Server: 8.2 (fixpack 15) Windows 2003 Domain-Users
    Client: 8.2 (fixpack 15)

    First i used db2 runtime clients 6.1 and all worked fine..

    Now I have to use runtime clients 8.2 ( external Software need this version) and the connection to the Server over ODBC need ca. 55 sec until i get a "Connection sucessfull tested"..
    In a db2cmd window the connection runs well and fast.
    Also with the other clients (6.1) I never had problems connecting with odbc.

    I used wireshark to sniff the networktraffic between client and server. (see gif)
    I don´t realy understand what the things meen, but here you can see the time (57sec) the connection need to finish.

    Hope someone can help me..

    Kind regards

    Have you explicitly activated the database (see the ACTIVATE DATABASE command) or does the first connection have to activate the database and potentially perform crash recovery?

    i did not used this command, because the database are still active since 2 months on this server.. I have this problem only from this 8.2 clients, other clients accessing this server work fine..
    The Database should be just started, because it is used by diffrend users.
