Brief Introduction to Oracle client

Yesterday I tried to use TNSPING on a remote company's computer to test the network condition, but I found that TNSPING could not be executed without installing the Oracle client. When learning Oracle, you may encounter Oracle client problems. Here we will introduce the solutions to Oracle client problems. Here we will share with you some ideas. It's easy to install an Oracle client in a remote location. It's almost a nightmare. The installation program is compressed to 453 MB, which is time-consuming and laborious. I just want to test the network, do you need such a large weekly subscription? In the future, there will be more such requirements, so we decided to re-package the client program.

1. Find a CLIENT with 10GR2 installed on a computer without an Oracle CLIENT, and only select Oracle Net and other required components for installation. Dizzy, it will take more than two hundred MB after the installation ).

2. By reading documents and using filemon and regmon, rip files in the following directories:
Zhu── BIN
├ ── NETWORK
│ ├ ── ADMIN
│ Mesg
─ ── Nls
│ ─ ── Data
│ Mesg
─ ── Oracore
│ Mesg
│ ─ ── Zoneinfo
├ ── Rdbms
│ Mesg
─ ── Sqlplus
Mesg

3. Export the Registry HKLM \ softwar \ Oracle and save it as ora. reg.

Ora. reg content:

 
 

  
  
Windows Registry Editor Version 5.00  
  
  
[HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE]  
  
  
[HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraClient10g_home1]  
  
  
"ORACLE_HOME"="D:\\oracle"  
  
  
"ORACLE_HOME_NAME"="OraClient10g_home1"  
  
  
"ORACLE_GROUP_NAME"="Oracle - OraClient10g_home1"  
  
  
"ORACLE_BUNDLE_NAME"="Enterprise"  
  
  
"NLS_LANG"="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"  
  
  
"ORACLE_HOME_KEY"="SOFTWARE\\ORACLE\\KEY_OraClient10g_home1" 
 
 

The Oracle client is described above.
