The client-side Oracle Wallet may be used for external authentication by the Capture Agent. See the Oracle documentation at https://docs.oracle.com/cd/B19306_01/network.102/b14266/cnctslsh.htm#g1033548 for instructions on setting up this secure password store.
Configuration of the capture agent to use external authentication requires only leaving out the --password parameter in its Capture CAB configuration file. Other methods for obscuring the Oracle password required by the Capture Agent are described in the section Create Oracle Capture CAB file .
Note: The tnsnames.ora and sqlnet.ora must be configured to specify the Oracle Wallet location.
