Existing Ingres Installation
To install Enterprise Access on top of an existing Ingres installation
1. Shut down your existing installation.
2. The II_SYSTEM environment variable must be defined and should refer to an existing installation.
3. Determine the Enterprise Access package you want to install, that is, "oracle" for Oracle, "db2udb" for DB2 UDB.
4. To start the installation, ensure the install tar file is available.
5. Enter the following command:
cd $II_SYSTEM/ingres
6. Extract the upgrade script and run it, as follows:
tar xvf/path_to_install_tar_file/gateway.tar gwinstall.sh
./gwinstall.sh /path_to_install_tar_file/gateway.tar gateway_type [gateway_type]
where gateway_type is the required host DBMS (for example, oracle).
Here are example commands for AIX:
tar -xvf /tmp/ea260605rs4us500.tar gwinstall.sh
sh gwinstall.sh /tmp/ea260605rs4us500.tar oracle
Note: The installation script, gwinstall.sh, allows you to install Enterprise Access in an existing Ingres installation while leaving the Ingres components unchanged.
