Custom Web Application Queries - Introduction
The Data Server includes a rtvquery servlet that you can optionally install and run on your application server. The rtvquery servlet enables custom browser-based applications to query information from caches in the Data Server. The rtvquery servlet is useful for obtaining internal data from the OC Monitor--data that the OC Monitor collects and does not include in displays. You can then use the data in your own custom application. The data is returned as a response to a HTTP request, which allows the data to be incorporated into any client capable of dealing with RESTful service.

rtvquery Servlet
The rtvquery servlet communicates with the Data Server via socket. If you are using multiple Data Servers, you must configure and install a rtvquery servlet for each Data Server. If you want to install multiple rtvquery servlets on the same application server, each must have a unique name.

The rtvquery servlet is intended to display tables from the Data Server at relatively low data volumes. For high data volume displays, the RTView Viewer application or Thin Client is recommended.

cachedocs Directory
Refer to the index.html documentation, located in the cachedocs directory, for information about target caches for queries.

For rtvquery servlet examples, see the <OCM Installation Directory>/rtvoc_XXXX/rtview/custom/rtvquery-samples directory.

To use the rtvquery servlet you must configure and install it. For details, see the following:

• Configure and Install rtvquery Servlet: This section describes how to configure and install the rtvquery servlet .
• Using rtvquery Servlet: This section provides information you need to obtain the internal data from the OC Monitor using the rtvquery servlet .
