LSF Version 7.3 - Administering Platform LSF

Version management components
218 Administering Platform LSF
Version command
The version command pversions is a tool provided to query the patch history and
deliver information about cluster and product version and patch levels.
The version command includes functionality to query a cluster or check contents of
a package.
The version command is not located with other LSF commands so it may not be in
your path. The command location is
LSF_TOP/7.0/install/pversions
Data schema update script
The update script for your data schema is a tool provided by Platform to update an
existing database before you patch the cluster. The update script modifies the data
schema so the database is prepared to handle data from an updated cluster.
Use the script that matches your database and cluster version. A patch may not
involve any change to the database, or it may require multiple scripts to update
different parts of the database.
Patch installer
The patch installer patchinstall is a tool provided to install patches on an existing
cluster.
The patch installer includes functionality to query a cluster, check contents of a
package and compatibility with the cluster, and patch or roll back a cluster.
Patch history
History The patch history is a record of information about patches installed with the patch
installer or the LSF installer, including products and patches installed, dates, and
location of backups required for rollback purposes.
The
pversions command retrieves and displays the version information. The
patch installer rollback feature retrieves the backup information.
History directory The patch history information is kept in the patch history directory. The directory
location is
LSF_TOP/patch by default.
The patch history directory is configurable during installation. See the
PATCH_HISTORY_DIR parameter in
install.config.
Patch backups
Backups The patch installer backs up the current installation before attempting to replace
files with the newer versions. The backups are saved so that rollback will be possible
later on.
Patches change relatively few files, but for an update release, all the files in the
cluster are backed up, so the amount of space required is large. The more patches
you install, the more space is required to save multiple backups.
Backup directory The patch backup files are kept in the patch backup directory. The directory
location is
LSF_TOP/patch/backup by default.
