onstat: Changing data structure...

We are developing a Client-Server application: Server: SOLARIS with INFORMIX-OnLine Version 7.13.UC2 Client: Windows-Clients with Centura Team Developer application Problem: If someone connects to the database using the client application, the commands "onstat" and "onstat -g ses" produce the error message: "Changing data structure forced command termination." and the error code 1. The command "onstat -g sql" works fine. Any suggestions? CU Robert

This may or may not be a problem. This message is actually displayed by onstat as the result of the SEGV signal handler in onstat. Since we don't lock all of the memory in the shared memory segments when the onstat command is being run, we might run into a SEGV while running through linked lists and such. There have been real problems with onstat in the past that caused this error as well. Why are you still on 7.13? While I can understand some hesitation for changing levels of the engine, I'm a suprised that anyone would still be on 7.1x with the year 2000 just arround the corner. The first part of the year 2K problem was implemented in 7.2 with the DBCENTURY parameter. >We are developing a Client-Server application: >Server: SOLARIS with INFORMIX-OnLine Version 7.13.UC2 >Client: Windows-Clients with Centura Team Developer application > >Problem: >If someone connects to the database using the client application, the >commands >"onstat" and "onstat -g ses" produce the error message: >"Changing data structure forced command termination." and the error code >1. > >The command "onstat -g sql" works fine. > >Any suggestions? > >CU >Robert Madison Pruet

For most UNIX versions, you need to be at either 7.24.UC7 or 7.30.UC7 to be Y2K complaint. See the following web page for exact information: http://www.informix.com/informix/products/year2000/table1.htm Take care. Clifton >Why are you still on 7.13?
