“Oracle *daily* TidBits” (#oratidbit) published on Facebook &Twitter, during weekdays in July 2019. Hope you find these helpful to learn something new or to remind you of its existence and use.
| #OraTidbit You can create Autonomous Database dedicated deployments. The order of deployment is Autonomous Exadata Infrastructure (#Exadata), Autonomous Container Database (CDB), Autonomous Transaction Processing Database (PDB). |
| #OraTidbit For dedicated deployment of Autonomous Database, you can choose to use Release Update (RU) or Release Update Revision (RUR) for your Autonomous Container Database maintenance. You have the option to skip maintenance runs for up to 2 consecutive quarters. |
| #oratidbit #db19c The COLOCATION_TAG parameter is an alphanumeric string that you can use with the CONNECT_DATA parameter of the TNS connect string. Clients with the same COLOCATION_TAG are routed to the same database instance in a RAC environment. |
| #oratidbit #ThinkAutonomous #OracleCloud In an Autonomous Database (ATP) dedicated deployment, you can create up to four Autonomous Container Databases (CDB) with up to 200 Autonomous Databases (PDBs) in each CDB. |
| #oratidbit #ThinkAutonomous #OracleCloud In an Autonomous Database (ATP) dedicated deployment, the Fleet Administrators create, monitor and manage Autonomous Exadata Infrastructure and Autonomous Container Database resources. |
| #oratidbit Use the -dbconfig command when Oracle ORAchk is not able to discover ORACLE_HOME or the name of the Oracle Database and you have multiple ORACLE_HOMEs in a system and each home is running multiple Oracle Databases. |
| #oratidbit #OracleCloud Infrastructure Bare metal DB systems consist of a single server running Oracle Linux 6.8, with locally attached NVMe storage. Each DB system can have multiple database homes, which can be different versions. Each database home can have only one database. |
| #oratidbit #AutonomousDatabase #ThinkAutonomous Oracle Autonomous Database (ATP & ADW) includes the Performance Hub to view real-time and historical performance data. |
| #oratidbit #db19c To enable automatic indexing, set the AUTO_IMPLEMENT_INDEXES initialization parameter to the Oracle database release number, say 19.3. You can disable automatic indexing by setting the AUTO_IMPLEMENT_INDEXES initialization parameter to NONE. |
| #oratidbit #db19c #OrclEM Beginning with Oracle Enterprise Manager 13.3 Plugin Update (PG) Release, Database version 19c is supported as both a Repository Database and a Managed Target Database. |
| #OraTidbit #ThinkAutonomous #AutonomousDatabase allows data file resize, autoextend on/off using ALTER DATABASE or ALTER PLUGGABLE DATABASE commands. ALTER TABLESPACE and CREATE TABLESPACE commands are not allowed. |
| #OraTidbit #ThinkAutonomous #AutonomousDatabase You can limit the storage allocated to a user by specifying a tablespace quota using the DBMS_CLOUD_ADMIN.GRANT_TABLESPACE_QUOTA procedure. |
| #OraTidbit The continuous_mine option for the DBMS_LOGMNR.START_LOGMNR package is desupported in Oracle Database 19c, and is no longer available. The CONTINUOUS_MINE functionality of the LogMiner package is obsolete. |
| #OraTidbit In the license included model of #AWS RDS Oracle service, you contact AWS Premium Support for both Amazon RDS and Oracle Database specific service requests. |
| #OraTidbit Autonomous Database (ATP/ADW) supports native authentication with #OracleCloud Infrastructure Object Store. Using native authentication you can use key-based authentication to access the Object Store (instead of using a username and password). |
| #oratidbit #OracleRAC Starting with 19c, the Grid Infrastructure Management Repository (GIMR) is optional for new installations of Oracle Standalone Cluster. No GIMR reduces functionality in CHAG, CHACTL, TFA. |
| #ortidbit Oracle Active Data Guard DML Redirect feature enables DML on the standby to be redirected to the primary to allow infrequent writes to run on the ADG standby database. This feature is not available on the authorized cloud environments (#AWS/#Azure). |
