You are working on a new Oracle Database 11g server, where only the software is installed and no database iscreated. You plan to create a database on this server using the Database Configuration Assistant (DBCA).Some of the requirements set for your database creation task are: 1.Configure the database to operate in shared server mode. 2.Disable automatic maintenance tasks such as optimizer statistics collection. 3.Configure a naming method to help the remote user connect to the database instance. 4.Use Automatic Storage Management (ASM) for storing the database files. 5.Configure daily database backup to flash recovery area. 6.Configure Enterprise Manager Database Control to manage the database. Which of these requirements can be met while creating the database()
You are about to plug a multi-terabyte non-CDB into an existing multitenant container database (CDB) as a pluggable database (PDB).
The characteristics of the non-CDB are as follows:
-Version: Oracle Database 12c Releases 1 64-bit -Character set: WE8ISO8859P15 -National character
set: AL16UTF16 -O/S: Oracle Linux 6 64-bit
The characteristics of the CDB are as follows: -Version: Oracle Database 12c Release 1 64-bit -Character
set: AL32UTF8 -O/S: Oracle Linux 6 64-bit
Which technique should you use to minimize down time while plugging this non-CDB into the CDB?()
You are required to migrate your 11.2.0.3 database as a pluggable database (PDB) to a multitenant container database (CDB).
The following are the possible steps to accomplish this task:
1. Place all the user-defined tablespace in read-only mode on the source database.
2. Upgrade the source database to a 12c version.
3. Create a new PDB in the target container database.
4. Perform a full transportable export on the source database with the VERSION parameter set to 12 using the expdp utility.
5. Copy the associated data files and export the dump file to the desired location in the target database.
6. Invoke the Data Pump import utility on the new PDB database as a user with the DATAPUMP_IMP_FULL_DATABASE role and specify the full transportable import options.
7. Synchronize the PDB on the target container database by using the DBMS_PDS.SYNC_ODB function.
Identify the correct order of the required steps.()
You upgraded from a previous Oracle database version to Oracle Database version to Oracle Database12c. Your database supports a mixed workload. During the day, lots of insert, update, and deleteoperations are performed. At night, Extract, Transform, Load (ETL) and batch reporting jobs are run.
The ETL jobs perform certain database operations using two or more concurrent sessions.After the upgrade, you notice that the performance of ETL jobs has degraded. To ascertain the cause ofperformance degradation, you want to collect basic statistics such as the level of parallelism, totaldatabase time, and the number of I/O requests for the ETL jobs.
How do you accomplish this?()
You notice a performance change in your production Oracle 12c database. You want to know which change caused this performance difference.
Which method or feature should you use?()
You are working on a 24X7 database. You want to design a backup strategy for your database that uses user managed backups. You want to be able to perform all backups while the database remains online.
Which statement about performing user-managed backups in a 24x7 environment is true?()
You are using a recovery catalog to maintain Recovery Manager (RMAN) backup information for yourproduction database. You have registered your production database and are performing regular backups.
Because of a new requirement you have added a few new tablespaces to your production database and youwant them to be included in backups.Identify two options for completing this task. ()(Choose two.)
