OAS 3.0: maximum number of interrupt handlers exceeded ?
Posted on 2001-08-25
I am doing a stress test to OAS 3.0 (NT 4.0 Enterprise SP5), using LoadRunner 6.5. When I attempt to put 70 users to login the Web page (through a PL/SQL cartridge, DAD on a remote Database). It failed and I found errors in "wrb.log":
'PLSQL Cartridge' 546 0 0x800ff `OWS-05104: Unable to attach to host database: [/ora/805], [xxxsid], [xxxsid.world]'
'PLSQL Cartridge` 648 1 0x400ff `ORA-00568: Maximum number of interrupt handlers exceeded'
Then I can't reach the Web page through the URL, with following error shown on the browser :
Error occured while accessing "/test/plsql/login" at <Date>
OWS-05100: Unable to connect due to Oracle error 568
PLSQL Cartridge: test
Please try again later
The only way I can access the URL again is to stop and start the Oracle Services in "Services" of Control Panel.
I have already set the maximum no of instance (WRB parameters for (PL/SQL) to 1000000 (min. no is 0). And the maximum connect count (www in Oracle Web Listener) to 338. But it doesn't work.
It seems okay when I put only one or two users loop running in 10 minutes.
I doubt that I need to config some more parameters for hundreds of users. Does it exist any limitations ? Or is it a SQLnet problem from the Web Server (NT) to the remote database (Oracle 8.0.5 on AIX) ?
Any help is highly appreciated.
