- B. CRS home directory (ORA_CRS_HOME)
- C. Oracle inventory directory
- D. group services directory (GSDJHOME)
- E. Oracle home directory (ORACLE_HOME)

After adding two new high-performance nodes to your existing eight-node Oracle Database cluster, you decide to remove the two oldest nodes from your cluster. You start by removing the instances from the nodes you are about to remove by using the Database Configuration Assistant (DBCA). During the execution, a problem arises and the DBCA terminates with a fatal exception. Before you contact Oracle Support, you want to create a Java-based tool trace file so that Oracle Support can assist you in resolving this issue as quickly as possible. How would you create this trace file?
- A. Set the SRVM_TRACE environment variable to TRUE before you execute the DBCA command.
- B. Set the DEBUG environment variable to TRUE before you execute the DBCA command.
- C. Set the SRVM_DEBUG environment variable to TRUE before you execute the DBCA command.
- D. Request extra information by adding the -d (debug) command line flag at the DBCA command line.
- E. Request extra information by adding the -v (verbose) command-line flag at the DBCA command line.
- F. There is no need to do anything special because Java-based tool tracing is enabling by default for DBCA.

- A. Set the DB_RECOVERY_FILE_DEST initialization parameter to the same value on all instances.
- B. Set the flash recovery area size to no smaller than 20 GB.
- C. Set the DB_RECOVERY_FILE_DEST_SIZE initialization parameter to the same value on all instances.
