Installation Disk Space Requirements

Before you install, verify that there is enough disk space in the target installation directory. The installer runs successfully when the target installation directory has sufficient disk space. For both new installation and upgrade, you need a minimum free space in the TEMP directory. The installer extracts the package contents to the TEMP directory and then installs the product on the desired disk.

Verify Disk Space Requirement
Before you install, verify that there is enough disk space in the target installation directory. The installer runs successfully when the target installation directory has sufficient disk space. For both new installation and upgrade, you need a minimum free space in the TEMP directory. The installer extracts the package contents to the TEMP directory and then installs the product on the desired disk.
The following are the space requirement to implement CA APM:
  • For New Installation:
     Minimum of 5-GB free space in the target install disk and an extra 2 GB free space for the TEMP directory
  • For Upgrade: 
    Minimum of 5-GB free space in the target disk, an extra 2 GB for the TEMP directory. Also consider extra free disk space depending on the size of the existing data (Smartstor data, Postgres DB, Traces DB, and any additional data)
Customize the TEMP Directory Path
Before you launch the installer, if the default temp directory does not have sufficient space, you can change the installer temp directory path to have the recommended disk space requirement.
In Windows, set the environment variable IATEMPDIR to your desired new temp directory path.
Follow these steps:
  1. Open the System, Advanced system settings window from the Control Panel.
  2. Click Advanced tab, Environment Variables.
  3. Select New under the System Variable group.
  4. Set the following properties:
    Name= IATEMPDIR
    Value = <new temp directory path>
  5. Save the settings and exit.
In Unix, set the following property to change the TEMP directory path:
IATEMPDIR=<new temp directory path>
Export IATEMPDIR
