After a system outage, a pump Extract or Replicat may get stuck on a trail file even if there are more trail files available in machine for the reader object to process. This issue occurs when the pump extract / Replicat read checkpoint RBA is larger than the local trail file size that it reads.
If using a OGG version higher than 10.4.0.81 , the error message will be like
If using a OGG version higher than V126.96.36.199.1, the error message is a bit misleading
2012-09-07 13:01:30 ERROR OGG-01091 Unable to open file "/u01/app/goldengate/dirdat/rt000068" (error 2, No such file or directory).
When you do info, it shows
REPLICAT XXXX Last Started 2012-09-07 14:28 Status ABENDED
Checkpoint Lag 00:00:00 (updated 02:05:27 ago)
Log Read Checkpoint File /u01/app/goldengate/dirdat/rt000067
2012-09-06 22:32:04.123161 RBA 197650300
when you list the trail files, both rt000067 and rt000068 exist, but rt000067 has smaller size than the RBA
This is the list of the files on Disk
-rw-rw-rw- 1 oracle dba 197640272 Sep 6 22:43
-rw-rw-rw- 1 oracle dba 83807478 Sep 7 12:46
So the Replicat is reading past the EOF of the trail file.
The same issue is also noticed when a disk space issue happens.
