Preparing to Install the CSE

Before you install the Client-Server Encyclopedia, perform these steps.

Follow these steps:

Verify that all models, subset, or child models are checked in.
Important! You lose work if you fail to perform this step. You will not be able to check in models or subsets that are created with the Second Prior Current Schema after installing CA Gen Release 8.5.

Note: For the schema designation for Current Schema, Prior Schema, and Second Prior Schema, see the Release Notes.
Ensure that the target location for the CSE installation has sufficient disk space. The following platforms require this amount of free disk space:
- HP Itanium requires 600 MB
- AIX requires 850 MB
Shut down all components of the installed CSE. There should be no programs running in the CSE owner account while installing the CSE.
To check for programs running in the CSE owner account, cseadmin, run this program show (ps) command:
```
$ ps -u cseadmin
```
The primary components are iefmd and iefrds.
When the system includes a CSE release that precedes AllFusion Gen 7, back up the earlier release of the CSE and the CSE databases.
Note: The USD does not manage the CSE releases that precede AllFusion Gen 7.

When updating from Advantage Gen 6.5 or an earlier release, we recommend using a different directory than the previous release for the CA Gen Release 8.5 CSE installation. If you are using the same location for your installation, delete the previous release except for the following files:
```
<install-dir>/iefcse.csh
<install-dir>/iefcse.sh
<install-dir>/exe/ds.cfg
<install-dir>/exe/es.cfg
```
Bring the computer system up to the Technical Requirements. Install CPU upgrades, memory upgrades, operating system upgrades, and DBMS releases as specified in the Technical Requirements.
