System database directory values
A system database directory exists for each instance of the database manager, and contains one entry for each database that has been cataloged for this instance. In Db2 Connect products, the system database directory contains information about the name, alias, node name, and authentication type of each database.
You can specify the following information in the system database
directory:
- Database name
- The same value that you wrote in the DCS Directory Parameters table.
- Database alias
- An alias for the IBM mainframe
database server. This name will be used by any application program
that accesses the database. By default, the value that you specify
for Database name is used.
Format: 1-8 single-byte alphanumeric characters, including the number sign (#), at sign (@), dollar sign ($), and underscore (_). It cannot begin with an underscore or a number.
- Node name
- The same value that you wrote in the Node Directory Parameters table.
- Authentication
- Specifies where the validation of the user's name and password will be made for connections originating from the Db2 Connect Server. The valid options are: SERVER, SERVER_ENCRYPT, CLIENT, KERBEROS, and SERVER_ENCRYPT_AES. There is no support for the GSSPLUGIN authentication type in the system database directory.
