Oracle configuration and use
1. Pay attention to the instance name and the corresponding table space when creating a database, and the settings of the rollback segment (see Oracle's corresponding book)
2, start SQL PLUS
3, log in to the database
My application environment login user name SB502, password SB502
Connect SB502 / SB502 (if it is connected to remote database using connection string Connect SB502 / SB502 @ alias)
4. Create a database orcl; (note that the corresponding authority should be given to the login user)
5, because I installed Oracle817, so put it into the environment variable in the corresponding lib directory of the WEB application in the WEBLOGIC81 installed in the Oracle directory. It writes into the lasspath of StarTwls.cmd to the launch script plus the Oracle driver to facilitate the configuration of the WebLogic8.1 connection pool.
Note: Oracle 8.17 and Pentium's four 1.7G CUP will have conflicts, and there is a problem that cannot be installed. At this time, you can copy the installation file of Oracle 8.17 to your hard drive, then search for "Symcjit.dll" file in the installation folder, you should find 2 and remove it properly. II. Example overview
database
1. There are two tables in the database ORCL that are automatically generated by CMP. The T_UIDGENERATOR has two fields: Name represents the application name, the UID represents the unique identification number of this app; T_LeaveApp has the following seven fields, represents the identification number of the leave, the employee number, the employee name, department, please leave the date, please fake days, please Reason.
Table T_UIDGENERATOR Table T_LEAVEAPP
Structural map
1, LeaveApp structure: Client Access data from the WEB request servlets (or JSP), servlet calls Session EJB --- LeaveAccess, and the access is implemented by the corresponding CMP EJB. (Note: The CMP is automatically completed by the EJB container to the database, all of you, is to rewrite the setXXX or getxxx method in the entity bean, then define CMP-Field in EJB-JAR.XML.)
2 LeaveAccessBean is a session ejb that encapsulates complex business interactions with entity Bean UidGenerator, LeaveApp, providing various data access interfaces for expression layers.
