ORA-31465: cannot obtain a lock on the subscription
Cause: A timeout occurred while trying to place a lock on the subscription. Another session had already acquired the lock on the subscription.
Action: Ensure the subscription name is correct and correct it if necessary. If it is already correct, try the operation again after the session holding the lock has released it.
Oracle ORA-31465错误表明无法获取订阅锁。这通常发生在您尝试执行复制操作时，如administer database replication，create master repository或者create database link。
