The following code used to work on Oracle 8.0 on Solaris.
Now, under Redhat 8.0 and Oracle 9i, when you run it several times in a row, it eventually seg faults and the only way to re-establish the connection is by restarting apache.
Our PHP is built with
./configure --prefix=usr/local/php --with-gd=/usr/local --with-png-dir=/usr/local --with-oci8=/oracle --with-apx2=/usr/local/apache/bin/apxs --with-jpeg-dir=/usr --with-zlib-dir=/usr --with-xpm-dir=/usr --enable-debug --enable-sigchild
This is not my code, and I do not use PHP, so I want to know first if there is a better way of writing this code. Can it successfully recover given that it dies for some reason on a query? Is there any more recoverable way of writing it?
Even if it's not optimal code, it should be slightly more recoverable than this.
print "Test";
putenv("ORACLE_SID=coastal");
putenv("ORACLE_HOME=/oracle");
putenv("TNS_ADMIN=/oracle/network/admin/tnsnames.ora");
$connection = OCILogon("user","xxx", "mydb") or die("Couldn't logon.");
$sql = "select count(*) from x";
$sql_statement = OCIParse($connection,$sql) or die("Couldn't parse statement.");
OCIExecute($sql_statement, OCI_DEFAULT) or die("Couldn't execute statement.");
$num_columns = OCINumCols($sql_statement);
OCIFreeStatement($sql_statement);
OCILogoff($connection);
PHP still runs after this code, as long as the page does not involve any other Oracle interaction.
thanks!

As our documentation describes, you need to set the environment vars BEFORE you start apache. Setting it in a script won't work: putenv("ORACLE_SID=coastal"); putenv("ORACLE_HOME=/oracle"); putenv("TNS_ADMIN=/oracle/network/admin/tnsnames.ora");I tryed to backtrace the error and that's what I've got: [root@cmn bin]# gdb /usr/local/apache/bin/httpd GNU gdb Red Hat Linux (5.2.1-4) Copyright 2002 Free Software Foundation, Inc.
