2.3.1 Prerequisites

Before configuring True Cache, complete the following steps.

  • Install the Oracle AI Database software on the True Cache nodes.

  • Ensure that a primary database is running on the primary node in archive logging (ARCHIVELOG) mode.

    The primary database must be in ARCHIVELOG mode to ship redo log files to the True Cache node. To see if the primary database is in ARCHIVELOG mode, enter the following SQL query: 

    SELECT log_mode FROM v$database;

LOG_MODE
------------
ARCHIVELOG

    If the primary database is not in ARCHIVELOG mode, restart it in mount mode, run the ALTER DATABASE ARCHIVELOG command, and open the primary database again.

  • Don't set LOG_ARCHIVE_CONFIG and LOG_ARCHIVE_DEST_n on the primary database. True Cache automatically configures these for the primary database.

  • If LOG_ARCHIVE_DEST is set on the primary database, remove it. LOG_ARCHIVE_DEST is incompatible with the LOG_ARCHIVE_DEST_n parameters. For more information, see LOG_ARCHIVE_DEST.
