I still think this problem is caused more often by restoring backups than by what you experienced. :) I've got to admit that I don't know understand how the problem would have occurred. You really should write it up and turn in a CAR so that we have an official record. Now, on to correcting the problem. The official procedure is (as you know): 1) Upload 2) Save all 3) Initialize 4) Reboot 5) Load all Or as you suggested upload the compound, save the compound, delete the compound, reload the compound. However, there is an unofficial procedure that can be used AT YOUR OWN RISK. Our you can bring in FS and do it at our risk. :) Be ready to practice, practice, practice before doing this with a real system. Still, it is helpful. Make a SAVE ALL on the on-line machine after an UPLOAD. Load it on an off-line machine into a CP of the same type and letterbug name. Delete the blocks that are in the ICC, but not the on-line CP. Exit the ICC At this point, you have a set of files on the off-line AW that are consistent with the configuration of the on-line CP. Those files are: The directory - /opt/fox/ciocfg/<cpLbug> The directories /opt/fox/ciocfg/<cmpdName> Where <cmpdName> is the name of any compound that has Sequence Blocks (IND, DEP, EXC, etc) or PLB blocks in it. Tar them off Tar them onto the on line machine. Now the workfile and the CP match. Use the CSA utilities to bring CSA in-line if necessary - boils down to dump to ASCII file, edit file, reload. Bingo, you are consistent without a reboot.

Ummm... Not nessessarily. My story (happened just this past week) On hiting the DONE key for a block edit, I got a pop up saying there was an error in communicating with the CP. Not good. SYSMON shows a CP with one side failed. I exit ICC and the time it takes is consistant with it doing a checkpoint. Quick trip to the downstairs to the rack room and sure enough, one side of the CP is red, the other green. Back upstairs, the operators see a flash of backrounds on screen where all backrounds turn yellow for 5 or 10 seconds. Look at SYSMON and it shows both sides of the CP are now ok. Time since initial error message around 10 minutes now. Everything looks ok, so back to editting. After a bit we notice that a block that was put in 15 or 20 minutes before the failure gets a NOT FOUND error when trying to edit it. Looking around we find that none of the edits made since the last checkpoint before the failure are in the CP, though they do appear in ICC. So, the first question is what exactly happened. It looks as if one side of the CP (the failed side) reloaded while the other side was checkpointing, then synced up (we saw no process bump). Is that possible? Thinking about it I don't know why not. (Oh, and the printers on that node are not up, so no messages.) Second is how to recover. We know exactly that all edits were made in a single compound. So, for this instance only, my advice to the customer is that the compound should be deleted and restored, either "delete-undelete" or save to disk, delete, restore from disk. There is a planned shut of the process area soon where this might be accomplished. Alex, your comments on both questions would be welcome >There are Helpful Hints on what to do > >You can also get CSA out of date this way.

Would this be in that On-Line Upgrade document that was floating around a while ago? Regards, William C. Ricker FeedForward, Inc.
