Using one user would make it harder to demonstrate the problem. Sorry I didn't include create user scripts etc. I retested with 4.3.10-dev and 5.0.3-dev binaries of a few minutes ago. I am using W2K with Oracle 9.2 client libraries. I am still seeing the usernames printed as SCOTT and HR, which is "incorrect". Previous Comments: ------------------------------------------------------------------------ [2004-10-12 07:20:03] [EMAIL PROTECTED] No, of course you should able to connect to Oracle from PHP using different logins. My question should be read in this way: "are you able to reproduce it under 1 user, but with different connections, because I was too lazy to create a new user in Oracle?". Btw, I've already created additional user and tested your code - your example works perfectly for me. ------------------------------------------------------------------------ [2004-10-12 05:38:56] cjbj at hotmail dot com The "business requirement" comes from the original report in http://forums.oracle.com/forums/thread.jsp?forum=178&thread=251141 I don't think the way $c1 is impacted by the second login is obvious or nice behavior. I feel the problem is related to some of the common OCI8 connection issues due to the caching and reuse of handles. It would be nice to resolve these issues. There is no Oracle-OCI reason why two users can't be connected at one time. I think it should be allowed in PHP. But if you think the PHP-OCI8 interface should not support concurrent connections, can a PHP error be generated at the time of the second OCINLogin()? ------------------------------------------------------------------------ [2004-10-10 17:02:43] [EMAIL PROTECTED] Chris, is it important to have different users in your example? Tested under 1 user (but using ociNlogin();) and it works fine. ------------------------------------------------------------------------ [2004-08-13 05:32:39] cjbj at hotmail dot com The given testcase has an extra semi-colon in the second query. The new testcase below shows that the initial connection is getting associated with the second user. Testcase: <?php function qry(&$c, $s) { echo "===>BEGIN<br>"; $rSth = OCIParse($c, $s); $rRet = OCIExecute($rSth); echo "<br>"; while ($succ = OCIFetchInto($rSth, $row)) { foreach ($row as $item) { echo ($item?htmlentities($item):' ')." "; } echo "<br>\n"; } echo "===>CLOSE<br><br>"; ocifreestatement($rSth); } $statement1 = "select user from dual"; echo "===>OCINLogin #1: Connect as SCOTT<br>"; $c1 = OCINlogon('scott', 'tiger', 'F10D' ); echo "===>Query first connection<br>"; qry($c1, $statement1); echo "===>OCINLogin #2: Connect as HR<br>"; $c2 = OCINlogon('hr', 'hr', 'F10D'); echo "===>Re-query first connection<br>"; qry($c1, $statement1); ?> Actual Output: ===>OCINLogin #1: Connect as SCOTT ===>Query first connection ===>BEGIN SCOTT ===>CLOSE ===>OCINLogin #2: Connect as HR ===>Re-query first connection ===>BEGIN HR ===>CLOSE Expected output is similar with the usernames in this order: SCOTT, SCOTT ------------------------------------------------------------------------ [2004-07-05 09:38:01] cjbj at hotmail dot com Description: ------------ Multiple logons within the same request cause handles to become invalid and queries to fail. Also see: http://forums.oracle.com/forums/thread.jsp?forum=178&thread=251141 To reproduce, restart Apache and run the following file. The same incorrect output occurs with ocilogon() inplace of ocinlogon(). Reproduce code: --------------- <?php ociinternaldebug(1); function qry(&$c, $s) { echo "<br>===>BEGIN<br><br>"; $rSth = OCIParse($c, $s); $rRet = OCIExecute($rSth); echo "<br>"; while ($succ = OCIFetchInto($rSth, $row)) { foreach ($row as $item) { echo ($item?htmlentities($item):' ')." "; } echo "<br>\n"; } echo "<br>===>CLOSE<br><br>"; ocifreestatement($rSth); } $statement1 = "select dname from dept"; $statement2 = "select user from dual;"; echo "<br>===>OCINLogin #1<br><br>"; $c1 = OCINlogon('scott', 'tiger', 'MYDB' ); echo "<br>===>Query first connection<br><br>"; qry($c1, $statement1); echo "<br>===>OCINLogin #2<br><br>"; $c2 = OCINlogon('hr', 'hr', 'MYDB'); echo "<br>===>Re-query first connection<br><br>"; qry($c1, $statement1); echo "<br>===>Re-query first connection<br><br>"; qry($c1, $statement2); ?> Expected result: ---------------- Three queries are successfully completed.
