Rerunning the Platform Pack Installer

You must rerun the JD Edwards EnterpriseOne Platform Pack Installer to support these scenarios:

• You want to install the Enterprise Server and the Database Server on physically different machines.

• You want to add an Enterprise Server environment to the Enterprise Server.

• You want to add a Database Server database to the Database Server.

• You want to reinstall the JD Edwards EnterpriseOne Foundation on the Enterprise Server.

• You want to reinstall the System Database on the Database Server.

When you first ran the Platform Pack installer, to complete the installation you ran the addacct.sh script to lock down permissions to this directory:

/u01/jdedwardsppack/e920

Prior to rerunning the Platform Pack installer for any purpose, you must run the installer_chmod.sh script to unlock and change permissions to allow the installer to execute. On the machine which you initially installed the Platform Pack:

1. Sign on as the root user.

2. Change directory to the location of the Platform Pack installer. For example:

   cd /u01/jdedwardsppack/e920_1/SharedScripts

3. Run the installer_chmod.sh script to change permissions so the Platform Pack installer can be re-run:

   . ./installer_chmod.sh

You should never reinstall any components without first deinstalling the components. If you select to deinstall the mandatory components you must also select to deinstall or have already deinstalled all related optional components. This table lists the mandatory and related optional components:

Server	Mandatory Component	Optional Components
Enterprise Server	JD Edwards EnterpriseOne Foundation	ES Production ES Prototype ES Development ES Pristine
Database Server	System Database	Production Databases Prototype Databases Development Databases Pristine Databases
