C:\oracle\instantclient_19_3PATH environment variable. If you have multiple versions of Oracle libraries installed, make sure the new directory occurs first in the path. Restart any terminal windows or otherwise make sure the new PATH is used by your applications.C:\oracle\instantclient_19_3\network\adminThis is the default Oracle client configuration directory for applications linked with this Instant Client.
Alternatively, Oracle client configuration files can be put in another, accessible directory. Then set the environment variable TNS_ADMIN to that directory name.
ODBC users should follow the ODBC Installation Instructions.
