1 Log in to the local Oracle database
sqlplus login local database
sys as sysadb
password
plsql login local oracle database ---------------------------------------------
1. The user created by himself, the instance name defaults to orac, and the state selects normal
ora-01017: invalid username/password;
Reason: Instance name problem, because the tablespace of the created key is pdb50 and the following data is based on it, so the instance name is also this.
This is how I create a key tablespace in pdb,
CREATE PLUGGABLE DATABASE pdb50 ADMIN USER c##test1 IDENTIFIED BY testdb
STORAGE (MAXSIZE 2G MAX_SHARED_TEMP_SIZE 100M) DEFAULT TABLESPACE
testdbdb DATAFILE 'D:\oracle\basiccatalog\oradata\orcl\testdbdb_001.dbf' SIZE 25M AUTOEXTEND ON;
2. How does the sys user log in to plsql?
To connect, you must modify the D:\oracle\soft\network\admin\tnsnames.ora file
Add the following paragraph below the file
#pdb This is mainly to add pdb records pdb50 is actually the name of pdb created by myself
pdb50 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
# (SERVER = DEDICATED) #Adding this line in my file will report an error
(SERVICE_NAME = pdb50) #Corresponding to the pdb of the query
)
)
