Hi list i upgraded an AIM*AT 2.5 on a 70 station to AIM*AT 3.0 and then to 3.0.2 In docs there are no messages about this kind of upgrade but i had a great number of problems. After installation i checked instance status and i found that wasn't running with error while executing ipchisti and fetchdog process. No data recorded I try to reinstall the package with same results... I try to check API status ( stopping an restarting ) and obtained the same error. At the end i decided (an hard decision) to remove the istance an rebuild a new one but i obtained the same problems.... with the addition of histmain.exe crash (Dr Watson Message ---> Exeption : access violation 0xc0000005 Address : 0x78002e40) At this point, with old data unreadable for the instance removal, i decided to reinstall the package after removing /opt/aim directory After this new installation i checked the status of the package with no istance and all worked fine. I create a new istance with a different name (hist02 inspite of hist01) and reload all rpts and all worked fine. After a reboot of the station i checked again the status and i found that hist02 (new istance) was running well but the log reported also messages about the old istance hist01 ( ipchisti and fetchdog process problems ). Another problem is no alarm history. Alarm history looked for old hist01 so i commited the station with the new hist02 After first boot all seemed to run well but after booting again the station the problem came back. This time alarm history looks for hist02 but a message advise that the system is unable to read hist02. At this point i ended my work. A very simple upgrade (as a foxboro guy told me) became hell. Now the station is collecting correctly but is not possible to read old data and no alarm history is available. I'm sorry for the long mail but i shoul describe all steps Is it "only" an unusual and not reproducible problem ? Is it possible to rebuild the old configuration for read again the old data ? Why the removed istance continue to exists somewhere ? I have million questions but i used much of your time ...(too much) Thanks in advance ----------------------------------------------------------------------- This list is neither sponsored nor endorsed by the Foxboro Company.
