Your database is in NOARCHIVELOG mode. The database has three online redo log groups, and each group contains three online redo log members. The online redo log members are stored across three hard disks, E, F, and G, respectively. Hard disk G crashed while the LGWR background process was writing redo information to the online redo log files. What effect will this crash have on the database?() The database will operate normally without generating any redo.。 The database will hang, and you must shut down and restart the instance.。 The database will crash, and you must recover the database from the point of failure.。 The database will operate normally and will generate minimal redo for the tables created with the NOLOGGING clause.。

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() 4 and 6。 2,3,4,and 6。 1,2,4,5,and 6。 1,2,3,4,5,and 6。
Your database contains two temporary tablespaces named TEMP and TEMP1. The TEMP tablespace is the default temporary tablespace for the database, and the TEMP1 tablespace was created at database creation. You want to increase the size of the tempfile for the TEMP tablespace and drop the TEMP1 tablespace from the database. The database is not using Oracle-Managed Files (OMF). Which statement must you use to ensure that when you drop the TEMP1 tablespace from the database, its corresponding operating system file is also deleted?()
