如果开启归档，请保证log_archive_start=true开启自动归档，否则只能手工归档，如果是关闭了归档，则设置该参数为false

注意：如果是OPS/RAC环境，需要先把parallel_server = true注释掉，然后执行如下步骤，最后用这个参数重新启动

1、开启归档

a. 关闭数据库shutdown immediate

b. startup mount

c. alter database archivelog

d. alter database opne

2、禁止归档

a. 关闭数据库shutdown immediate

b. startup mount

c. alter database noarchivelog

d. alter database open

归档信息可以通过如下语句查看
