Oracle Client and Configuration Files
Oracle Client and Configuration Files
For ASM, Dbvisit Replicate uses bequeath connection and therefore has to use the ASM home as the client and sets the ORACLE_HOME accordingly (setup wizards asks for the ORACLE_HOME when ASM is in use).
For all other Oracle connections, Dbvisit Replicate uses SQL*Net connections. As it comes with it's own Oracle client, it has to be told where to look for sqlnet.ora/tnsnames.ora files. Setup wizard will ask for TNS_ADMIN.
In order of precedence:
- The DDC setting TNS_ADMIN can be used to select the correct configuration files.
- TNS_ADMIN can be also specified in the environment.
- The DDC setting ORACLE_HOME also selects the correct configuration files; note that this is set if ASM is in use.
- ORACLE_HOME can be also specified in the environment.
- Current directory is searched last.
These are standard Oracle precedence rules, with the only addition that DDC file can override variable specified in the environment.
