Oracle forgot to unlock scott's solution during installation

Recently, I began to learn about Oracle and expressed silence for the redo system caused by various problems during the installation process.

(1) Question 1: After the 64-bit operating system is installed, select the java.exe file. Sqldeveloper flash back, because after the 64-bit operating system is installed, the generated JDK version is 32-bit.

Solution: Disable all Oracle services. Delete the X: \ Oracle11 \ product \ 11.2.0 \ dbhome_1 \ jdk folder. Replace the 64-bit jdk. Restart the service. Problem Solving

 

(2) Question 2: The scott user is forgotten to be unlocked during installation. Only the system user is allowed.

Solution: use SQL plus to log on. The specific user name is system. The password is the password you set. Use the following name to unlock the scott user and set a password for the scott user.

// Unlock scott user

Alter user scott account unlock;

// Set the password to tiger for scott.

Alter user scott identified by tiger;
