Status: Open
Bug Type: OCI8 related
Operating System: Solaris 9
PHP Version: 5.1.2
New Comment:
OCIPing requires 10.1 or 10.2 OCI client libraries. It will (or
should) return a nice error when the database server is 8.1 or 9.2.
This won't help PHP validate the connection as intended when connected
to these older databases. The oci8 extension should just use
OCIServerVersion.
The OCI Developers are against the concept of pinging for each
connection because it is an unneccessary round-trip between OCI client
and database server.

That's what Oracle is telling us.
This is directly from our ticket with them:
I think there are 2 things you can do to fix your problem.
1. Install the 10.2 listener in the box where your 10.1.x or your 9.x
database are running and use that listener to listen for your
databases.
2. Fix the OCI8 driver for PHP so it does not use OCIPING at all
We're awaiting further response from Oracle because their response
conflicts with all the documentation I've been able to find on OCI and
the OCIPing function.

So you're effectively saying that OCIPing() which exists in OIC is not
supported by Oracle servers 8 and 9 and causes them to crash?
This sounds really.. hmm.. weird, because I was recommended to use
OCIPing() namely by Oracle developers.

It might be a good idea get the Server Version with a call to
OCIServerVersion rather than relying on the OCI_xx_VERSION defines.
Any of the developers care to comment?
#if OCI_MAJOR_VERSION >= 10 && OCI_MINOR_VERSION >= 2
/* OCIPing() is usable only in 10.2 */
OCI_G(errcode) = PHP_OCI_CALL(OCIPing, (connection->svc, OCI_G(err),
OCI_DEFAULT));
#else
char version[256];
/* use good old OCIServerVersion() by default */
OCI_G(errcode) = PHP_OCI_CALL(OCIServerVersion, (connection->server,
OCI_G(err), (text*)version, sizeof(version), OCI_HTYPE_SERVER));
#endif

Oracle is claiming OCIPing isn't a supported in anything less than
oracle 10.2

Description:
------------
This isn't a bug in PHP, but I'm submitting it since Oracle currently
has no patch available and it's cause isn't obvious.
Using the Instant Client 10.2 and PHP 5.1.2 connecting to Oracle
9.2.0.7 we began seeing ORA-07445 errors immediately after upgrading to
the versions listed. They may appear to occur intermittently, but they
can happen as frequently as the oci8.ping_interval value.
I've traced it down to the OCIPing call in the oci extension.
It turns out any calls to OCIPing cause the error in the server.
Workaround:
In php.ini [oci8] section, set:
oci8.ping_interval=-1
I'll provide updates about possible patches from Oracle as soon as
they're able to respond.
