Description of problem: Installation of Oracle database (not installation of the oracle-server package itself, but installation of catalog, db setup, etc...) unnecessarily starts the listener before the listener is properly setup. Starting the listener without a proper listener.ora leads to the listener to be connecting to 0.0.0.0 (its internal default behavior), which will fail in an IPv6 only setup. Version-Release number of selected component (if applicable): oracle-server-scripts-10.2.0.51-6 How reproducible: Always Steps to Reproduce: 1. IPv6 only environment, Satellite 5.4.1 installation 2. Check /var/log/rhn/install_db.log Actual results: Error: Starting /opt/apps/oracle/web/product/10.2.0/db_1/bin/tnslsnr: please wait... TNSLSNR for Linux: Version 10.2.0.4.0 - Production Log messages written to /opt/apps/oracle/web/product/10.2.0/db_1/network/log/listener.log Error listening on: (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521)) TNS-12545: Connect failed because target host or object does not exist TNS-12560: TNS:protocol adapter error TNS-00515: Connect failed because target host or object does not exist Listener failed to start. See the error message(s) above... Expected results: No error like the above. Additional info: This error is not fatal to the installation, but should probably be resolved for a smooth Satellite IPv6 installation.
