2.2.2 Creating True Cache with DBCA

Follow these steps to create True Cache with Oracle DBCA.

1. Copy the password file, and optionally the Transparent Data Encryption (TDE) wallet, from the primary database to the True Cache node. You can use either of the following methods:

   • Manually copy the primary database's password file (and optional TDE wallet) to any location on the True Cache node.

   • Run a DBCA command on the primary database to package the password file (and optional TDE wallet) into a configuration BLOB file. Then copy the file to the True Cache node and ensure that the file is owned by the Oracle Home user.

     Use the following command to prepare the configuration BLOB file on the primary database:

     ORACLE_HOME/bin/dbca -configureDatabase -prepareTrueCacheConfigFile -sourceDB primary_db_sid_or_db_unique_name -trueCacheBlobLocation primary_db_config_blob_path -silent

     Example:

     $ORACLE_HOME/bin/dbca -configureDatabase -prepareTrueCacheConfigFile -sourceDB primdb1i -trueCacheBlobLocation /tmp/blob_loc2 -silent

     For descriptions of the parameters, see configureDatabase.

2. On the True Cache node, run the -createTrueCache command to complete the True Cache configuration and start True Cache.

   Choose one of the following command formats, depending on the method that you used to copy the primary database's password file (and optional TDE wallet) to the True Cache node in step 1.

   • If you manually copied the password file (and optional TDE wallet), use this command:

     ORACLE_HOME/bin/dbca -createTrueCache -gdbName true_cache_global_name -sid true_cache_sid -sourceDBConnectionString primary_db_easy_connect_string -passwordFileFromSourceDB password_file_path -sgaTargetInMB sga_memory_size -pgaAggregateTargetInMB pga_memory_size -silent

     Example using a password file:

     $ORACLE_HOME/bin/dbca -createTrueCache -gdbName tcdb1 -sid tcdb1 -sourceDBConnectionString primary.example.com:1522/primdb1i.example.com -passwordFileFromSourceDB /tmp/password_loc2/orapwddbmc1 -sgaTargetInMB 20000 -pgaAggregateTargetInMB 4000 -silent

   • If you created the configuration BLOB file, use this command:

     ORACLE_HOME/bin/dbca -createTrueCache -gdbName true_cache_global_name -sid true_cache_sid -sourceDBConnectionString primary_db_easy_connect_string -trueCacheBlobFromSourceDB true_cache_config_blob_path -sgaTargetInMB sga_memory_size -pgaAggregateTargetInMB pga_memory_size -tdeWalletLoginType AUTO_LOGIN -listeners listener_name -silent

     Example using a TDE wallet:

     $ORACLE_HOME/bin/dbca -createTrueCache -gdbName tcdb1 -sid tcdb1 -sourceDBConnectionString primary.example.com:1522/primdb1i.example.com -trueCacheBlobFromSourceDB /tmp/blob_loc2/blob.tar.gz -sgaTargetInMB 20000 -pgaAggregateTargetInMB 4000 -tdeWalletLoginType AUTO_LOGIN -listeners LISTENER -silent

   For descriptions of the parameters, see createTrueCache.

   Note:

   For Oracle RAC primary databases, set the -sourceDBConnectionString parameter to SCAN:port/service_name.
