Patch Installation Overview
When installing patches, you have the option to install multiple patches (batch mode) or individual patches.
Installing patches in batch mode
The batch patch installer allows you to install multiple patches to an Environment at the same time. The installer's logic evaluates patch files to determine the following:
-
Are the files all valid Lawson patch files?
-
Have the patches already been installed on your system?
-
Have the patches been superceded by another patch?
The installer will only install patches that it determines to be valid.
The batch patch installer runs only in command line mode. You can run the batch patch feature in interactive command line mode (where you will be prompted to proceed with each phase of the installation), or in unattended mode.
Installing individual patches
You can install patches individually using either GUI mode or command line mode.
-
The GUI instructions are the same as for a customer update (CU) installation. See Installing Infor Lawson Core Technology Updates.
-
For instructions for running the installer in command line mode, see Using the Lawson Installer and GlobalPerms Viewer from the Command Line.
Un-installing patches
You can use the installer to remove an individual patch. Patches cannot be removed in batch mode.
-
The product must be installed.
-
The patch you are removing must be installed. Removing a patch will automatically remove any superceding patches.
-
A higher service pack must not have been installed.
-
Backup directories are in place. If you are using the default backup directory, your backup files are in $LAWDIR/system/backup. If you changed the backup directory, check the BACKUPDIR value in $LAWDIR/system/install.cfg to determine where your backup directory resides.
-
You must have the .jar file for the patch you want to remove.
-
Post-install steps must be manually completed; for example, if the patch affected an .ear file, you must redeploy the backup .ear file to the application server.
