1.4 Considerations for Using True Cache

Consider these points when deciding whether to use Oracle True Cache.

• You need to configure enough memory for True Cache so your most frequently accessed data will stay in memory.
• True Cache only needs a small amount of storage for the standby redo log files. Configuration files like control files, the SPFILE, and temporary data files are automatically created.
• True Cache is a read-only cache, so you can't directly update the cache, but you can use DML redirection to indirectly update the cache.
