This parameter is available only for Oracle.
The fully-qualified file name identifying the Oracle tnsnames.ora file that contains the Oracle ASM connection parameters. This configuration parameter is required only when the connection parameter information required for ASM does not exist in the tnsnames.ora file pointed to by the pds_tns_filename configuration parameter.
<not configured>
A valid Oracle tnsnames.ora file that contains the connection parameters to the Oracle ASM server. This file normally resides in the ASM instance's ORACLE_HOME\network\admin directory.
Setting of the configuration parameter is only required when the Oracle ASM product is being used to manage Oracle online redo or archive redo storage.
This parameter is required only when the pds_tns_filename configuration parameter is not populated, or the tnsnames.ora file pointed to by configuration parameter pds_tns_filename does not contain the connection definition for the ASM connection to be used. This may occur if the primary Oracle instance and ASM instance was installed in different ORACLE_HOME locations, resulting in different tnsnames.ora files for each server.
WARNING! The Replication Agent process must have read permission to this file. Access failures prevent the Replication Agent from connecting to the Oracle ASM server.
