Operate on the main library:

SQL > ALTER SYSTEM SWITCH LOGFILE

After a few more operations, wait for a short period of time depending on the network speed. After a period of time, query the specified situation on the main database:

SQL > SELECT NAME,SEQUENCE#,ARCHIVED,APPLIED FROMV$ARCHIVED_LOG ORDER BY SEQUENCE#

If the returned result "APPLIED" is "YES" or only the last one is "NO", it means that all the archive logs have been archived, and then go to the slave database to operate:

Prepare the library operation:

SQL > ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCLE; SQL > ALTER DATABASE OPEN; SQL > ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT FROM SESSION
