Prerequisites
Installing MDS Core
Before you install the DDL Gateway package, install the MDS Core package (mdsbase) on the system you are using as the DIM Update server.
  1. Use the PUT utility or mdsgwyinstall command to install the DDL Gateway package (mdsgwy) on the DIM Update server.
    The DDL Gateway files are installed in the following directory:
    • MDS_installation_directory/gateway
    where MDS_installation_directory is one of the following:
    • /opt/teradata/mds
    • a nonstandard location if that option was selected when you installed the MDS Core package

    The DDL Gateway does not start when it is installed. The next time the system starts, the DDL Gateway starts automatically. You can start the DDL Gateway manually using the following command:

    • /etc/init.d/mdsgwy start
    When the DDL Gateway is initially installed, the status of the system might be Down and a message similar to the following might be sent to the MDS log:
    09/18/11 15:31:43|PID-523|5|CGwaySocket::Get HostByAddr(153.64.14.126) returns ‘SMP001-4’

    The first name specified for a node in the /etc/hosts file is the primary node name for the node. This is the name that must be used for a node defined for a system in the MetaManager GUI. Correct the etc/hosts file or the MetaManager node names.

    In the /etc/sysctl.conf file, the mdsgwy package automatically increases the system tunable parameters to the following values:

    • kernel.msgmnb=2097152
    • kernel.msgmni=7899
    • kernel.msgmax=65536

    The following services are added to the /etc/services file on the designated DIM Update server.

    TxServer 56969/tcp # MDS Gateway Server
RSiMsg 56970/tcp # RSG Server

    Changes to the /etc/services file are done as a result of installing the DDL Gateway. The changes might have been previously made as a result of installing the MDS Action Processor or RSG.
