- This is a little after the fact, but I have some questions about
- recovery, on a Pyramid MIS S server, running Online 4.1.
-
- I will pass on the details I have heard from the person on site.
- The system in question was running along fine, when everything
- hung. The logs were not full. Bouncing the application programs
- did not help, so it was decided to bounce Informix.
-
- The Informix log shows that OnLine was initialized, Physical recovery
- started, and completed, restoring 648 pages. For six hours after
- that, dots flew across the screen, over and over and over again.
- It appeared to be reading, maybe something again and again. Logical
- Recovery never completed. The engineer on site finally aborted the
- logical recovery and restored via archives (owwwwww!).
-
- I remember when 4.0 had a problem in recovery when the logs were filled,
- and it looked the same way. One time, Informix was able to patch
- something it looked like there was nothing in the Logical logs, and the
- system came back up.
-
- Can someone offer a guess as to what was actually occurring, and what
- we could have done to avoid going to the archive (without Informix
- patching)?
