Verify Temporary Disk Space and Permissions

Verify Temporary Disk Space and Permissions

Verify that your environment meets the minimum system requirements for the temporary disk space, permissions for the temporary files, and the Informatica client tools.
Disk space for the temporary files
The installer writes temporary files to the hard disk. Verify that you have 1 GB disk space on the machine to support the installation. When the installation completes, the installer deletes the temporary files and releases the disk space.
To install Informatica with the application services enabled, verify a minimum disk space of 18 GB and a memory of 6 GB RAM. Out of the 18 GB disk space, 14 GB disk space is required for the product installation binaries. Based on the runtime configurations that you perform, the Informatica services might use a disk space around 13,846 MB. 1 GB disk space is the temporary disk space used.
Permissions for the temporary files
Verify that you have read, write, and execute permissions on the
/tmp
 directory.
