Creating an SSI-compliant custom server

You may have to make changes to your custom servers to ensure that they run correctly on a single system image; this is known as being SSI-compliant. Changes may be needed because the custom server work directory ($CUR_DIR/ca/cs_name_dir) will exist on NFS, and it will be mounted on to each machine in the single system image. There will be only one copy of the directory at one location, and that is on the database server; this copy is made available to all clients through NFS. Any configuration or data files located in this directory will therefore be shared, and could cause problems to such custom servers running on a single system image.

Follow these rules to make a custom server SSI-compliant:
