| Question ID 21741 | Which three statements are true about Automatic Workload Repository (AWR)?
|
| Option A | All AWR tables belong to the SYSTEM schema.
|
| Option B | The AWR data is stored in memory and in the database.
|
| Option C | The snapshots collected by AWR are used by the self-tuning components in the database
|
| Option D | AWR computes time model statistics based on time usage for activities, which are displayed in the v$SYS time model and V$SESS_TIME_MODEL views.
|
| Option E | AWR contains system wide tracing and logging information
|
| Correct Answer | B,C,E |
Explanation Explanation: * A fundamental aspect of the workload repository is that it collects and persists database performance data in a manner that enables historical performance analysis. The mechanism for this is the AWR snapshot. On a periodic basis, AWR takes a "snapshot" of the current statistic values stored in the database instance's memory and persists them to its tables residing in the SYSAUX tablespace. * AWR is primarily designed to provide input to higherlevel components such as automatic tuning algorithms and advisors, but can also provide a wealth of information for the manual tuning process.
| Question ID 21742 | You upgraded your database from pre-12c to a multitenant container database (CDB) containing pluggable databases (PDBs).
Examine the query and its output:
Which two tasks must you perform to add users with SYSBACKUP, SYSDG, and SYSKM privilege to the password file?
|
| Option A | Assign the appropriate operating system groups to SYSBACKUP, SYSDG, SYSKM.
|
| Option B | Grant SYSBACKUP, SYSDG, and SYSKM privileges to the intended users.
|
| Option C | Re-create the password file with SYSBACKUP, SYSDG, and SYSKM privilege and the FORCE argument set to No.
|
| Option D | Re-create the password file with SYSBACKUP, SYSDG, and SYSKM privilege, and FORCE arguments set to Yes.
|
| Option E | Re-create the password file in the Oracle Database 12c format.
|
| Correct Answer | B,D |
Explanation Explanation: * orapwd / You can create a database password file using the password file creation utility, ORAPWD. The syntax of the ORAPWD command is as follows: orapwd FILE=filename [ENTRIES=numusers] [FORCE={y|n}] [ASM={y|n}] [DBUNIQUENAME=dbname] [FORMAT={12|legacy}] [SYSBACKUP={y|n}] [SYSDG={y|n}] [SYSKM={y|n}] [DELETE={y|n}] [INPUT_FILE=input-fname] force - whether to overwrite existing file (optional), * v$PWFILE_users / 12c: V$PWFILE_USERS lists all users in the password file, and indicates whether the user has been granted the SYSDBA, SYSOPER, SYSASM, SYSBACKUP, SYSDG, and SYSKM privileges. / 10c: sts users who have been granted SYSDBA and SYSOPER privileges as derived from the password file. ColumnDatatypeDescription USERNAMEVARCHAR2(30)The name of the user that is contained in the password file SYSDBAVARCHAR2(5)If TRUE, the user can connect with SYSDBA privileges SYSOPERVARCHAR2(5)If TRUE, the user can connect with SYSOPER privileges Incorrect: not E: The format of the v$PWFILE_users file is already in 12c format.
