Use the new parameters in the installFixPack command to update an
existing Db2
pureScale
to a new version 11.5 fix
pack level.
Before you begin
- Ensure that you meet all of the requirements before you install a fix pack. Refer to Preparing to install a fix pack.
- Ensure that you are logged in as root.
- Issue db2stop
command.
About this task
This task uses the new capabilities of the installFixPack command to
update an existing Db2
pureScale instance to the
latest fix pack in offline mode. These new capabilities simplify the process of updating the
instances and automate the update of additional software components. To update the cluster for a
Db2
pureScale
instance, specify the instance name in the enhanced installFixPack command.
Procedure
To update an existing Db2
pureScale instance to a new
fix pack level:
- Install the new fix pack level on all hosts in the Db2
pureScale instance by
issuing the installFixPack command from the fix pack installation media
directory.
The media directory must be accessible to the root and the instance user from all
the members, secondary CF and primary CF. For example, to update to Fix Pack 1, issue the
installFixPack command on each host as
follows:
media-dir/installFixPack -p FP-install-path -I InstName -offline -l install-log-file -t trace-file-name
where
FP-install-path is the directory where you want to install the fix pack and
media-dir is the directory where you extracted the fix pack image.
FP-install-path must be the same on all hosts.Note: The
installFixPack command must be run sequentially on each host; the command cannot be run
concurrently or in parallel.
- Run the db2instance -list command to
ensure that the cluster is in a consistent state. If there are any
alerts of inconsistent state in the cluster, refresh the resource
model as the instance owner:
db2cluster -cm -repair -resources
- Determine whether the offline fix
pack update was successful in all members and CFs.
For
example, to verify the update to Fix Pack 1, issue the
installFixPack command
as follows:
media-dir/installFixPack -check_commit -I instance-name -t trace-file-name
-l check-commit-log-dir
If
the command output shows any problems, fix them before you continue
with the next step.
-
Commit the DB2® instance to the new level. For example, to
commit the update to Fix Pack 1, issue the installFixPack command as
follows:
media-dir/installFixPack -commit_level -I InstName -l commit-log-dir
where
media-dir is the directory where you extracted the fix pack image.
- Start the database manager in all members and CFs by issuing
the db2start instance command in each host as follows:
su - InstName
db2start instance on host-name
where
InstName represents the instance
owner name.
- Start the database manager for the instance by issuing
the db2start command as follows:
su - InstName
db2start
exit
where
InstName represents the instance
owner name.
-
To uninstall the previously installed Db2 copy, run the
db2_deinstall command:
DB2DIR/install/db2_deinstall -a
where
DB2DIR is the installation path of the previously installed Db2 copy.
