ORA-12528:TNS:listener:all appropriate instances is blocking new connectionsThe ORA-12528 problem is that the service in the listener uses the dynamic service, although the instance starts, but does not register to listen. The instance is registered to the listener through the Pmon process, and the Pmon process needs to be started in the Mount state. So it caused the above error.There are three ways to solve this problem:1, the monitoring set to static;2. Append in Tnsnames.ora (

subsentence standard. The new column feature allows most applications to rebound, reducing the lock overhead. It also locks the configuration file from Repeatable Read (RR), Read Stability (RS), or Cursor Stability (CS) to Uncommitted Read (UR ). Uncommitted Read avoids database locking. Applications can maintain the integrity of database transactions by using the new timestamp column in the application update SQL statement. The new timestamp column
