When using plsql us, no need, we try not to install oracle, because the oracle too
went on to say about plsql, oracle is not installed using the steps;
1. Personal local environment
OS: win10
not install oracle
2. Download a instantclient , remember to 32-bit, plsql does not support 64-bit
https://pan.baidu.com/s/1k-nKN9hmOLTv0ZycA9mMlQ extraction code: 14qj I Baidu cloud disk sharing, you can download
3. create a directory for instantclient
I can for example: D: \ oracle \ instantclient_11_2
creates two files in the folder:
sqlnet.ora and the tnsnames.ora
sqlnet.ora content:
the tnsnames.ora says:
tnsnames.ora value according to the actual needs its own database to configure
and add a system variable:
variable name: TNS_ADMIN
variable value: D: \ oracle \ instantclient_11_2 (previously mentioned directory is created)
4. Install PL / SQL Developer, and configure the connection parameters of the oracle:
open PL / SQL, Tools -> the Preferences
5. restart plsql, test, OK it!
If the error: ORA-12154: TNS: could not resolve the connect identifier specified.
Then your system variables (for details see Step 3) did not set or set incorrectly! Please check!
The last query data may be garbled: to provide a solution
and then create a system variable, set the variable name: NLS_LANG, the variable value: SIMPLIFIED CHINESE_CHINA.ZHS16GBK or AMERICAN_AMERICA.AL32UTF8 (variable value determined in accordance with the actual situation), can be determined
