Data Replication provides the following additional key files in the installation root directory:
CachedData.sqlite
The SQLite database that stores the headers of redo log files that the Extractor has read from disk, including archived redo logs and redo logs that are in RMAN backup sets. The Extractor creates this database file if the extract.oracle.use_log_file_header_cache runtime parameter is set to the default value of 1. The Extractor uses cached headers instead of re-reading backup sets or redo log headers for faster processing.
DataReplication.key
Contains the Data Replication license key value.
config.xsd
An xml schema file that defines the format of the Data Replication configuration files.
SM.db3, SM.db3-shm, SM.db3-wal
The SQLite database files that store the Server Manager settings.
SM_stat.db3
The SQLite database that stores the statistical data for the Server Manager. The Server Manager uses it to calculate the latency of the end-to-end replication.
