在做11gR2单实例转换为RAC的过程中,出现ORA-25152错误
Cause
ORA-25152: TEMPFILE cannot be dropped at this time。发生该错误的原因是,rconfig在转换RAC过程中,会DROP当前TEMP表空间。当前数据库TEMP表空间正在被使用就会导致ORA-25152,tempfile无法被删除的错误。这也是Oracle的一个bug:Bug 13912880 - RCONFIG FAILS WITH SQLFATALERROREXCEPTION: ORA-25152: TEMPFILE CANNOT BE DROPPED (Doc ID 13912880.8)
Solution
关闭当前RAC实例,重新启动源数据库,删除源数据库中tempfile
ALTER DATABASE TEMPFILE '/data01/temp01.dbf' DROP INCLUDING DATAFILES;
或者将tempfile全部致为offline状态
alter database tablespace temp tempfile '/data01/temp01.dbf' offline;
然后再运行rconfig进行转换。
在rconfig时出现该错误,不知道大家还有没有别的更好的方法?

The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.
