Description:
------------
Hardware: Power7 LPARS
OS: AIX 7.1 tech level 1 service pack 2
Web servers middleware: httpd-2.2.21 32 bit (prefork), php 5.3.10 32 bit, ibm_db2 1.9.2 32 bit, ibm db2 9.7.0.x run-time client 32-bit
DB servers: db2 enterprise server edition 9.7.0.5 using TSA for HA

Using persistent connections, fail over of db makes php app take up to an hour before reconnection works.  Switching from persistent to regular connections fail over of db, php app can immediately continue using it.

This application is going to be a large deployment (starting at thousands of active users and going to 10s of thousands of users) and persistent connections are going to be required in order to meet our performance requirements (web application response times < 5 seconds).

Hi Rodney,
 I think this is the same error which we have discussed over the email and we already have given the patch for this.

Thanks,
Rahul
