Hello.<br>Oracle client installator sets up some environment variables. The main thing is adding path to ORACLE_HOME\bin directory to PATH.. Having 2 or more oracle clients on the same machine can cause some problems if you do not provide the explicit path to tnsnames.ora. <br>
The solution can be setting the explicit path somehow in apache_install.bat or in httpd.conf (for example for cgi-bin section) or any other way.<br>There are 2 (or 3) things you have to set up:<br>%ORA_HOME% <br>%TNS_ADMIN% (%ORACLE_HOME\network\admin%)<br>
ORACLE_SID (think it is not necessary)<br><br>regards, michael<br>
