- Summary: tbtape seems to be trashing my root dbspace

- Have the following hardware, OS, and Informix . . .
-
- IBM RT
- AIX 2.2.1
- Informix OnLine v4.00.UD4
-
- Here's the problem . . .
-
- After initializing rootdbs and shared memory without any
- difficulties I use ISQL to create a couple of databases, fill
- one of them up with records and the other is simply empty.
-
- Now I wish to back-up this entire configuration to tape. So I
- use the Archive option from within tbmonitor. I then choose
- the option to Create, mount the tape in the drive, select "0"
- for a level 0 archive and then receive the following error
- message:
-
- Error reading from the disk, Error No. = 5.
-
- If I don't shutdown OnLine, I can still access the databases
- but if I do shutdown OnLine, I get the following error messages
- when I attempt to bring it back up:
-
- Bad Primary Chunk '/dev/rootdbs'
- tbinit: fatal error in shared memory initialization
-
- I'm fairly certain there's nothing wrong with the tape
- perameters I'm using because, oddly enough, if I only create
- the first database, I can back-up the system without it
- corrupting the rootdbs. It's only after I add the second
- database and attempt to back it up that it trashes rootdbs.
-
- If I make no attempts to back-up the OnLine partitions, OnLine
- goes up and down just fine.
-
- Now when I went to school, I was always of the impression that
- back-up utilties are for the preservation of your data. Maybe I'm
- missing something but this tbtape program just doesn't seem to be
- fitting the mold here too well.
-
- Has anyone run into this before? Know a fix? Could this be related
- to improper setting for shared memory and semaphores? If related to
- shared memory etc., could someone please email me either their
- /etc/master file or the relavent stanzas from it?
-
- Thanks.
