Verifying disk space and open file limits before installing IBM Connections

On all operating systems, ensure that you have 6 GB of temporary disk space. On AIX® and Linux™, set the Open File Descriptor limit to at least 8192 before installing IBM® Connections.

Procedure

Check that the /tmp folder on UNIX/Linux systems or the %TEMP% folder on Windows™ systems has at least 6 GB before installing Connections Content Manager. If there is not sufficient disk space, then set the environment variable IATEMPDIR to point to the location where there is at least 6 GB. To update the IATEMPDIR environment variable:
- On Windows:
  1. Navigate to Control Panel > System and Security > System > Advanced System Properties > Advanced tab > Environment variables.
  2. Click New in the System variables section.
  3. Enter IATEMPDIR for the variable name; and then enter the desired location in the variable value field.
  4. Click OK twice.
- On AIX/Linux:
  1. Edit the /etc/profile file and add in the following line to the end of the file:
```
 export IATEMPDIR=<new location> 
```
    where <new location> is a location on your machine that has enough free space (at least 6 GB, preferably more).
(AIX and Linux only) The Open File Descriptor limit must be set to at least 8192 for the user ID that is installing IBM Connections.
- Open a command line to view the current Open File Descriptor limit:
```
ulimit -n
```
- If the number is less than 8192, increase the number for the user.
  If you are installing as the root user, add the following line to the user's profile file and save the file:
```
ulimit -n 8192
```
  If you are using a non-root user account to install IBM Connections, ask the administrator to add the following line to the /etc/security/limits.conf file:
```
non-root_account hard nofile 8192
```
Note: On small deployments were the database server is on the same machine, the limit might need to be higher as specified by the database's requirements.
