The procedure maybe used for some component store locate component data to the SYSAUX tablespace from its current tablespace. B. The procedure may be used for some component store locate component data from the SYSAUX tablespace to another tablespace. C. All the components may be moved into SYSAUX tablespace. D. All the components may be moved from the SYSAUX tablespace. 【题目示意】 考察了SYSAUX表空间的管理方法 【解析】 当数据库创建时，SYSAUX表空间被作为SYSTEM的辅助表空间安装。已经安装并使用独立表空间的数据库组件都可以放在SYSAUX表空间中。如果SYSAUX表空间不可用，数据库内核功能仍然运转。使用SYSAUX表空间的特性将会失败或功能可用性会受到限制。 … [Read more...]
【Q&A】OCP 1z0-060 QUESTION 1: About Managing Temporary Tablespaces in a CDB
QUESTION 1 Your multitenant container (CDB) contains two pluggable databases (PDB), HR_PDB and ACCOUNTS_PDB, both of which use the CDB tablespace. The temp file is called temp01.tmp. A user issues a query on a table on one of the PDBs and receives the following error: ERROR at line 1: ORA-01565: error in identifying file ‘/u01/app/oracle/oradata/CDB1/temp01.tmp’ ORA-27037: unable to obtain file status Identify two ways to rectify the error. A. Add a new temp file to the temporary tablespace and drop the temp file that that produced the error. B. Shut down the database instance,restore the temp01.tmp file from the backup,and then restart the database. C. Take the temporary tablespace offline, recover the missing temp file by applying redo logs, and then bring the temporary tablespace online. D. Shutdown the database instance, restore and recover the temp file from the backup, and then open the database with RESETLOGS. E. Shut down the database instance and then … [Read more...]
