Processing of ora-01172 ora-01151

A machine, the disk was found to scan, it is estimated that the shutdown encountered problems yesterday, Oracle appeared after ora-01172 ora-01151
Hurry to find information to solve, and encountered a ORA-12514 error, the first solution to this error is as follows:
Enter the following information in the listener. ora file:

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = oracle) service name
(ORACLE_HOME = E: \ oracle \ product \ 10.2.0 \ db_1) db_home
(SID_NAME = oracle) # This is the service you want to add
)
(SID_DESC =
(PROGRAM = extproc)
(SID_NAME = PLSExtProc)
(ORACLE_HOME = E: \ oracle \ product \ 10.2.0 \ db_1) # This Service ensures that you can use external processes, such as C Programs.
)
)

Then configure the tnsnames. ora file and add the following content:

Oracle =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = localhost) (PORT = 1521 ))
)
(CONNECT_DATA =
(SERVICE_NAME = test) corresponds to the above service name
)
)

You can test the connection as follows:
Tnsping oracle

After Oracle9i, the background process PMON automatically registers the service name defined in the system parameter SERVICE_NAMES In the listener. The default value of SERVICE_NAMES is DB_NAME + DOMAIN_NAME. You do not need to specify the service name of the listener in the listener Configuration File listener. ora. However, when the PMON process is not started when the database is closed, the Instance name of the listener will not be automatically registered, so the use of sqlplus sys/his @ orc0 as sysdba will have a ORA-12514 error.

Enter set display verbose in lsnrctl, and then run the Command service to check whether the service status is READY, which indicates the service name automatically registered by PMON, and UNKNOWN indicates that the service is manually in LISTENER. database Service configured in ORA.

As
As for media restoration:
Ora-01172 ora-01151, the solution is as follows:
