To install the DITA Open Toolkit:
For best performance, set this location to a local path on the Content Platform Engine server. Specifying a UNC path allows one DITA Open Toolkit location to support multiple DITA rendition engines. The advantage of a shared location is that there is only one location to update with new versions of the DITA Open Toolkit. The disadvantage is that loading the DITA Open Toolkit over the network is slower.
Some installations of the DITA Open Toolkit on platforms other than Windows have incorrect permission settings for the Apache Ant tools. If you get the following error in the p8_server_error.log file, verify that file permissions in the DITA-OT/tools/ant/bin directory are set to grant execute privilege.
