查看修改Oracle10G归档日志空间的限制
在Oracle10G中,默认的归档路径为$Oracle_BASE/flash_recovery_area。对于这个路径,Oracle有一个限制,就是默认只能有2G的空
在Oracle10G中,,默认的归档路径为$Oracle_BASE/flash_recovery_area。对于这个路径,Oracle有一个限制,就是默认只能有2G的空间给归档日志使用,可以使用下面两个SQL语句去查看它的限制:
1. select * from v$recovery_file_dest;
2. show parameter db_recovery_file_dest(这个更友好直观一些)
当归档日志数量大于2G时,那么就会由于没有更多的空间去容纳更多的归档日志会报无法继续归档的错误。
如:“RA-19809: limit exceeded for recovery files
ORA-19804: cannot reclaim 10017792 bytes disk space from 2147483648 limit
ARC0: Error 19809 Creating archive log file to '/u01/app/Oracle/flash_recovery_area/ORCL/archivelog/2007_04_30/o1_mf_1_220_0_.arc' ”这时我们可以修改它的默认限制,比如说将它增加到5G或更多,也可以将归档路径重新置到别的路径,就不会有这个限制了。
更改限制语句如下:
alter system set db_recovery_file_dest_size=5368709102 (这里为5G 5x1024x1024x1024=5G)
alter system set db_recovery_file_dest_size=10737418240

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.

The installation package can be downloaded from the Oracle official website. Environment variable configuration: Edit /etc/profile file, set Java and Hadoop environment variables, so that the system can find the installation path of JDK and Hadoop. 2. Security configuration: SSH password-free login to generate SSH key: Use the ssh-keygen command on each node
