Oracle Database new installation connection string

Set the environment variable TNS_ADMINoracleproductapp5networkadminsamples to read the new tnsnames. ora location. You can use the client to connect to the oracle program.

Set the environment variable TNS_ADMIN =/oracle/product/app5/network/admin/samples to read the location of the new tnsnames. ora, and use the client to connect to the oracle program.

The new database is installed after cutover, and the client login is normal. The apache/cgi-bin program is faulty. The sqlnet. log is as follows:

Fatal NI connect error 12170.

Cause:

The tns resolution string specifies the problem.

Set the environment variable TNS_ADMIN =/Oracle/product/app5/network/admin/samples to read the location of the new tnsnames. ora, and use the client to connect to the oracle program to run normally.

However, the cgi-bin program cannot be executed normally because of the environment variable transmission relationship of http.

Two solutions:

1. Run the environment variable in apache and restart apache.

2. Reply tnsnames. ora to $ ORACLE_HOME/network/admin.
