Abstract: Describes how to upgrade database from HP-V4.0B(2) to HU-V4.0G
How to convert a v3.3 database on HP-UX 10.x since InterBase HU-V4.0G does not
have a bridge to v3.3 version databases.
HP-V4.0B(2) was tested and certifed by InterBase QA on HP 9.05; HU-V4.0G was
tested and certified on HP 10.20 and 10.01. Therefore, we recommend that
all customers backup and restore all of their v3.3 databases with HP-V4.0B(2)
to move them to the v4.0 format, then install HP 10.20 and InterBase HU-V4.0G.
The following method uses the bridge on HP9 as a migration utility to convert a
v3.3 database to a v4 database on HP10. Our use of this method is based on HP's
statement that HP9 and HP10 are binary compatible with each other.
Here are the steps:
1. Install both HP-V4.0B(2) and HU-V4.0G on the same HP10 machine by
following the installation notes included with both releases.
2. Make a copy of the original database. (The 3.3 database in this case.)
3. Follow these steps to run the HP-V4.0B(2) kit:
a. Make sure no one is accessing the system remotely:
ps -ef | grep inet | grep -v grep
If you see any gds_inet_server processes, do a kill -15 on them.
b. Drop the existing lock manager process and remove the semaphore values:
c. Check for shared memory and remove any shared memory, as in the
ipcrm -m313 -m551 -m678 ...
d. Check the system for semaphores and remove the InterBase semaphores, as
in the following example:
ipcs -s -a
ipcrm -s202 -s401 -s435 ...
e. Remove the InterBase symbolic link:
rm /usr/interbase (Must be superuser to do this)
f. Link /usr/interbase to the HP-v4.0B(2) kit. For example:
ln -s /test/interbase/HP-V4.0B /usr/interbase
4. Backup the v3.3 database. Be sure to include the -t option.
/usr/interbase/bin/gbak -t -v -z /test/atlas.gdb /test/atlas.gbk
5. Remove the InterBase symbolic link:
rm /usr/interbase (must be superuser to do this)
6. Repeat step 3 but link /usr/interbase/ to HU-V4.0G kit instead HP-V4.0B(2) kit.
ln -s /test/interbase/HU-V4.0G /usr/interbase
7. Restore the v3.3 database backup.
/usr/interbase/bin/gbak -c -v -z /test/atlas.gbk /test/new_atlas.gdb
8. Remove the HP-V4.0B(2) kit from your system.
