1. When the virtual machine installed, and then in the Virtual Machine Installed Oracle, when the next restart, encounter Oracle reported ora-12514 error, there are a lot of online solutions, this place to write a solution:
Open the file: % oracle_hoem %/Network/admin/listener. ora in
Sid_list_listener =
(Sid_list =
(Sid_desc =
(Sid_name = plsextproc)
(ORACLE_HOME = D:/Oracle/Oracle10g)
(Program = EXTPROC)
)
Add:
(Sid_desc =
(Global_dbname = Oracle)
(ORACLE_HOME = D:/Oracle/Oracle10g)
(Sid_name = Oracle)
)
Finally changed:
Sid_list_listener =
(Sid_list =
(Sid_desc =
(Sid_name = plsextproc)
(ORACLE_HOME = D:/Oracle/Oracle10g)
(Program = EXTPROC)
) (Sid_desc =
(Global_dbname = Oracle)
(ORACLE_HOME = D:/Oracle/Oracle10g)
(Sid_name = Oracle)
)
)
Idea: sid_name is the service name, and the idea is to modify its Oracle installation path
2. After this error, and then reported: ora-0134 error, the solution is as follows:
Enter the command line of the VM and start the database instance.
For example:
For example, CMD-> sqlplus/nolog
Conn sys/admin @ orcl as sysdba;
After login:
SQL> startup
After the instance is started, everything is normal. There are many reasons for such errors. If this is the case.
