All nodes in the cluster use a single places catalog index, located in a shared file system.
Before installing IBM® Lotus® Quickr™ you must create a directory for the index on a shared file system server, such as one of the servers in the cluster. Make sure the directory has enough space for your deployment. Typically 1 GB is enough for any deployment. The primary node must have write-access to the directory, and all other nodes must have read-access.
Specify the directory when you install the primary node. In the installation program the directory is called the Shared Resources for PlaceCenter Collections
location. See the topic on installing the primary node on your environment's operating system for more information, for example see Installing the primary node on Windows
The installation program creates the index and creates place and template sources pointing to it.
If the index is stored on a system using Network File System (NFS) protocol, the Network File System cache interval must be smaller than the places collection interval (defaulted to 30 seconds).
In clusters the primary node manages the index and adds new content. A places catalog is installed on all nodes, but administrator requests (such as scheduled data collection) are redirected to the primary node, so the primary node actually performs the function. Index collection settings are stored in a database and so updated information is displayed in the administrative interface on all nodes in the cluster.
