Prerequisite: The Oracle database has been successfully installed.
Installation environment: Win7 64-bit
Oracle installation version 11g 64-bit
Question 1) Oracle comes with Sqldeveloper
Let me enter the full path of the Java.exe and then report a warning
Warning:could not find jvm.cfg! In ' C:\Program files\java\jdk1.8.0_151\jre\lib\jvm.cfg '
The other person's experience is that the installed Sqldeveloper is 32-bit and the JDK is 64-bit, so no.
Solution) under 64-bit sqldeveloper or 32-bit JDK
But the oracle11g I'm pretending to be is 64-bit.
I didn't try to solve it.
configuration of PL/SQL developer
Suppose the ORACLE11G server class is installed in the app folder on the F drive
PL/SQL Developer Plsqldeveloper---plsql----instantclient_11_2 (client) in E-drive Plsqldeveloper
|__plsql Developer
(1) Environment variables
Nls_lang = Simplified Chinese_china. Zhs16gbk
Tns_admin = E:\PLSQLDEVELOPER\PLSQL\instantclient_11_2 (#---> Installation path) "is a problem."
Actually, after looking at http://blog.csdn.net/mr_li13/article/details/52226006, I found
Direct settings tns_admin = F:\app\zml\product\11.2.0\dbhome_1\NETWORK\ADMIN (Directory for Oracle Server class installation)
You can save the process of configuring Tnsnames.ora later
"Note" If you want to trouble a little afraid of error, can be like a red letter configuration, and then copy and paste F:\app\zml\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.org
To #\plsql\instantclient_11_2\network\admin (if not created by yourself)
Running PL/SQL developer will find
Unable to connect to Oracle server There are two options SYSDBA, Sysoper
With SYSDBA login, the maximum, for SYS user (super user sudo), can do anything
After logging in with Sysoper permissions slightly more than SYS, for public users, can not create a delete database, only the full recovery of the database, can not be fully restored
Reference http://blog.csdn.net/mr_pang/article/details/50032515
Then cancel and go to the PL/SQL Developer page
(2)PL/SQL Developer Environment Setting (emphasis)
Tools----> Preferences-----> Connections

Setting up the OCI Library: E:\plsqldeveloper\plsql\instantclient_11_2\oci.dll (OCI Library in Oracle client)
You can go in when you're done.
