For details on the vdba command, see the CommandReference Guide.(Optional) Delete Install Directory (UNIX)Note: This step is optional but recommended.The Ingres installation procedure on UNIX starts by extracting the installsubdirectory from the Ingres distribution.You should delete the old contents of that directory first, as follows:cd $II_SYSTEM/ingresrm –rf installNote: This step is required only for an in-place upgrade on UNIX.Install IngresTo install Ingres, see the Ingres installation instructions for your platform.In-place upgrades only: During the installation process, the DBMS Serversetup asks whether all databases are to be upgraded; answer No. The installprocedure automatically upgrades the iidbdb. If the upgrade of iidbdb fails, seethe appendix “Troubleshooting Upgradedb.”After the iidbdb is upgraded, the DBMS Server setup attempts to upgradeimadb and install Remote Command Server objects into imadb.
