Verifying that sufficient disk space is available

If an installation fails, confirm that the computer has sufficient free disk space in the temporary directory, which is required by IBM® Information Server, in addition to the disk space required for the installed components.

Symptoms

Installation fails with an error message similar to the following messages:

WARNING: C: has insufficient space to install the items selected. 1200.4 MB 
additional space would be needed to install the selected items.

WARNING: / partition has insufficient space to install the items selected.
1200.4 MB additional space would be needed to install the selected items.

Causes

The drive or partition does not have enough free disk space in the temporary directory in addition to the disk space required for the installed components.

Diagnosing the problem

When the IBM Information Server installation program determines that there is insufficient free disk space for a successful installation, the installation program only identifies which disk or file system has insufficient space, not which directories.

Resolving the problem

Verify that the required free disk space is available for the installation:

Analyze your disk space and plan your installation.
- In the Explorer window, right-click the drive or folder and click Properties to view the disk space.
- Type this command to view the file system space in KB:
```
df -k
```
Ensure that the temporary directory has 500 MB free disk space. (See the system requirements for the exact amount). If your temporary directory has less than the required free disk space, use the -is:tempdir command to designate a temporary directory that has the required free disk space. Your temporary directory does, however, require some additional free space, even when you use the -is:tempdir command to designate another temporary directory.
Ensure that you have the required free disk space to install IBM Information Server and the IBM Information Server components.
If you are planning a large deployment, install the metadata repository and the IBM WebSphere® Information Analyzer analysis database to a location that has more disk space.
