1. Scope of this Technote: About RDS installation modes



          table 1: RDS versions and installation modes

    Depending on what version and what installation mode you chose, you need to manage the credentials of usertdsadmin the appropriate way. This Technote covers all modes (Apache/Tivoli, Standalone/Corporate/OS).

2. Thetdsadmin can refer to several unrelated user accounts


    The tables below show how to avoid confusion regarding accountstdsadmin.


              table 2: rules for every installation mode


              table 3:tdsadmin passwords

    Finally, please note thattdsadmin also refers to the name of the db2 instance used by RDS (which makes it a 3rd tdsadmin for you to be aware of!). However, this is strictly internal to db2. If you're not familiar with db2, simply ignore thistdsadmin.

3. Accounttdsadmin is mandatory to manage RDS


4. Accounttdsadmin is not mandatory to manage your Corporate LDAP (RDS Tivoli or Apache in Corporate mode)


    tdsadmin is meant only to manage RDS and is not required in your Corporate LDAP, as seen in table 2.


5. About thetdsadmin OS profile


    Table 2 shows that :

      5.1. Atdsadmin OS user is mandatory in every RDS Tivoli installation mode.

      This is required to connect to the underlying db2 database. See section 9 to know how to change it.

      5.2. Atdsadmin OS user is not required in any of the RDS Apache installation modes (even in OS authentication mode!).

      Every other user's information will be retrieved from the OS, but the information for usertdsadmin is stored only in RDS. If you have created atdsadmin user in the OS, it will have no impact on RDS and their passwords won't be synchronized.

6. tdsadmin password lifecycle

    The 'tdsadmin' password never expires in RDS".

    This applies to all installation modes.

    If you have RDS Tivoli, then, as stated in section 5.1, you also have atdsadmin user in your OS. It has been created automatically by the RDS installation. Its password's expiration policy is set by your OS settings.


7. Instructions to change the tdsadmin password in RDS

    These instructions apply to every RDS version and every installation mode.

    When you know the currenttdsadmin password follow the steps below, otherwise refer to the section 8 "Instructions to reset" of this Technote.

    Steps:


      1. Login to the RDA web-based interface as usertdsadmin

      (consult the RDS manual to know how to start RDA)

      2. Change the password for usertdsadmin

8. Instructions to reset thetdsadmin password in RDS Tivoli 9. Resetting the tdsadmin password in your IBM Rational Change installation
    During the installation of Rational Change, the Admin User enters the URL for Rational Change Admin in a web browser and is first prompted to configure the RDS installation details. Here, you enter the RDS URL, and thetdsadmin username and password. This is a one time operation and this information is written to the following file: <CHANGE_INSTALL_DIR>/jetty/webapps/change/WEB-INF/wsconfig/rds_config.xm


    When thetdsadmin username or password is changed or the RDS URL is changed you need to do the following:

    1. Delete the file <CHANGE_INSTALL_DIR>/jetty/webapps/change/WEB-INF/wsconfig/rds_config.xm
    2. Restart Rational Change
    3. Login to Rational Change as the admin user
    4. You will be prompted to configure RDS once again
    5. Enter the new RDS URL, tdsadmin username and password
