Can the Oracle Names Server version 8 (Oracle 8) be used to store database name of Oracle 7.3 and let its client using SQL Net 2.3 access it without problem. I'm not sure if there is a conflict between SQL Net 2.3 and Net80. I am thinking of using Oracle NamesServer80 in providing the connect string instead of TNSNAMES.ORA; i.e., we are currently using TNSNAMES.ORA in connecting to different Oracle Databases version 7.3. I do not want to use the version of Names Server provided by the Oracle7.3 because it is hard to configure as compared to the latest version.
