I get the following messages in my Apache 1.3.27 error log whenever I try to use OCILogon:

Here is the script I tested with:

<?

$SID = "(DESCRIPTION = 
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.140)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = TESTDB.WORLD)
    )
)";

$conn = OCILogon ("scott", "tiger",$SID);

print "Connected!<br>\n";
?>

Here are my configure lines:

For apache :

OPTIM="-g -m64" CFLAGS="-DDYNAMIC_MODULE_LIMIT=0" ./configure --mandir=/usr/local/man --activate-module=src/modules/php4/libphp4.a --enable-module=php4 --server-uid=www --server-gid=www

For PHP

CFLAGS="-g -m64" ./configure --with-apache=../apache_1.3.27 --with-xml --with-oci8=/usr/local/oracle/OraHome --with-zlib --enable-inline-optimization --enable-bcmath --enable-debug

They were both compiled with gcc-3.2.

Here are the environment variable settings from my httpd.conf:

SetEnv ORACLE_BASE /usr/local/oracle
SetEnv ORACLE_HOME /usr/local/oracle/OraHome
SetEnv ORACLE_SID TESTDB.WORLD
SetEnv TNS_ADMIN /usr/local/oracle/OraHome/network/admin/tnsnames.ora
SetEnv TWO_TASK /usr/local/oracle/OraHome/network/admin/tnsnames.ora
SetEnv NLS_LANG English_America.WE8ISO8859P1

And here is the backtrace:

This is with Oracle 9i Release 2.

Using Apache's  SetEnv doesn't work for PHP/Oracle. You have to set these really in Apache's environment (e.g. in apachectl).

If that alone doesn't help: did you see the "big fat note" at <http://www.php3.de/manual/en/ref.oci8.php>:

If your webserver doesn't start or crashes at startup:  Check that Apache is linked with the pthread library: [...]

Ok, I had put those SetEnv statements in Apache to see if they would help. I do have the same environment variables set in apachectl when I run Apache.

And I did read the note. Here is output from ldd:

        /usr/platform/SUNW,Sun-Blade-100/lib/sparcv9/libmd5_psr.so.1

Could the fact that it's linked to both the pthread and the thread library be causing a problem? If so, how do I prevent it from linking to the thread library?
 [2002-11-06 10:14 UTC] bdabney at dallasnews dot com
Ok, doing an ldd on /usr/lib/64/libpthread.so.1 answered that question. It uses libthread.
