手动建库(10.2.0.1)后,在建EM时,运行命令:
emca -config dbcontrol db -repos create
出现如下的错误:
ORA-06550: line 1, column 21:
PLS-00302: component 'VALID' must be declared
ORA-06550: line 1, column 7:PL/SQL: Statement ignored
发现VALID是的dbms_registry包的valid的过程。看来手动安装完,默认没有安装这个包。这样问题就简单了。
这个package的创建,需要运行下面二个运行文件。注意一定要第一个先运行,否则会报错。
1) ?/rdbms/admin/prvtcr.plb
2) ?/rdbms/admin/catclust.sql

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
