4.3 ORA-00228错误优化
优化ORA-00228错误处理配置的最佳实践：
4.3.1 优化重做日志管理
SQL> create or replace procedure optimize_redolog as
v_disk_used_percent number;
v_redolog_count number;
begin
— 获取磁盘使用率
select round((total_blocks – free_blocks) / total_blocks * 100, 2) into v_disk_used_percent
from v$recovery_file_dest;
— 获取重做日志组数量
select count(*) into v_redolog_count
from v$log;
— 如果磁盘使用率超过80%，建议清理
if v_disk_used_percent > 80 then
dbms_output.put_line(‘Disk usage is ‘ || v_disk_used_percent || ‘%’);
dbms_output.put_line(‘Redo log groups: ‘ || v_redolog_count);
dbms_output.put_line(‘Recommendation: Clean up disk space or add redo log groups’);
end if;
end optimize_redolog;
/
Procedure created.
# 2. 执行优化存储过程
SQL> set serveroutput on
SQL> exec optimize_redolog;
Disk usage is 85%
Redo log groups: 3
Recommendation: Clean up disk space or add redo log groups
PL/SQL procedure successfully completed.
# 3. 应用优化建议
SQL> alter database add logfile group 4
‘/oracle/app/oracle/oradata/FGEDUDB/redo04.log’ size 1024M;
Database altered.
# 4. 切换重做日志
SQL> alter system switch logfile;
System altered.
# 5. 创建定时任务
SQL> begin
dbms_scheduler.create_job(
job_name => ‘OPTIMIZE_REDOLOG_JOB’,
job_type => ‘STORED_PROCEDURE’,
job_action => ‘OPTIMIZE_REDOLOG’,
start_date => systimestamp,
repeat_interval => ‘FREQ=DAILY;INTERVAL=1’,
enabled => true
);
