Re: archecker warning about orphaned control page
Posted in 2003
Hi
Looking at the pg_flags (0x4000), it's a archive control page for dbspace
and chunks information, and it's also a tape trailer page (0x0020). It's
expecting a tape header page and hence the orphaned control page warning.
Once the orphaned page is detected, no information is recorded for that
dbspace/chunk, which can later cause the subsequent errors.
Were the databases consistent prior to the physical backup, was oncheck
run? Was the backup done with onbar and archecker invoked through the onbar
command line, or was the backup done with ontape and archecker invoked as a
standalone utility? It's not clear why the dbspace/chunk header pages
didn't make it to the archive.
thanks. Davis.

Does anybody know what this warning in the archecker log means:
WARNING: Orphaned control page(pg_flags 0X4020) found.
...and whether it leads to these errors later on:
ERROR: Error(2) failed to
open(/tmp/archeck_workspace-ol_qadb_05/SAVE/PT.00400001)
ERROR: Unable to open a partition file 0X00400001.
ERROR: Failed to locate partition page 0X00400001.
ERROR: Missing Partition pages - All tables might not be checked.
Thanks!
