BadWindow (invalid Window parameter) reporting from an Oracle application.

[skt_skt]

OS HP-UX 11.11

The oracle application works with the Xserver(Xhp) on the server.There are some service requests processed from the application everyday and 1% of the total requests fails with the below errors.It is often observed during the peak hours.(pointing to failures are more when there are more requests).

We had used the xscope tool to capture the information passing between the Xprogram and the oracle application.

As far as our analysis till now , this is what we understood.--"the application requesting WindowID's which are no longer available."

Spawned Process 12465
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 15 (X_QueryTree)
Resource id in failed request: 0x5400001
Serial number of failed request: 737
Current serial number in output stream: 737
below is the startup script used.

Did any one phase any similar issue?I am hiding some more inforamtion9from the troubleshooting phase) as i dont want you to limit to a particular direction.

Who ever participate(spend time) will be rewarded.

Shalom,

This is another in a long list of problems with X windows settings and Oracle report.

This will be solved with adjustments in the xvfb settings.

Nothing jumps off the screen at me right now.

You may find searching the Oracle tech forums will find you a configuration file that defeats this problem.

SEP,

Do u recollect anything specific xvfb setings? like Filedescriptors or screen size etc..

Error is reported in oracle appliation(report/form) logs. Oracle program will be at the client side and the Xprogram will be the server.
