-
-This example shows how to store the state of CORBA servants in
-persistent memory. The example is a variation of the Grid example in
-$TAO_ROOT/examples/Simple/grid.
-
-The server hosts the Grid servant. A client sets some values in the
-grid. These values are written out by the server in to a
-memory-mapped file, at which point the server shuts down. A new
-server is then started, which reads from the same memory-mapped file.
-Another client (named persistent_client) then reads and prints the
-values from the locations where the original client stored the values.
-
-server:
--------
-
-server [-d debug] -o <ior_output_file> -m <memory_pool>
-
-Options:
--------
--o Outputs the ior to the file
- The ior is the reference using which the client can interact with
- the target server object.
--m Name of the memory pool.
-
-
-When the server is started, you should see as the first line of output
-something that looks like
-
- iiop:1.0//danzon.cs.wustl.edu:10015/P35ad159600081a38/child_poa/server
- (-ORBobjrefstyle url)
-or
- IOR:000000000000001649444c3a43756269745...
- (-ORBobjrefstyle ior)
-
-client:
--------
-
-client [-d] [-x] [-f <Server_ior_file>] [-k file://<ior_output_file>]
- [-w] [-h] [-v]
-
-Options:
--------
--d Debug flag
--x Tells the server to shutdown at the end of the test.
--f Reads the server ior from the file
--k IOR or The IOR can also be given in the format like file://[file.ior]
- with the full path
-
--w Width of the grid
--h Height of the grid
--v Value that needs to be the starting point for storage. The value
- that is stored will be this value + location id.
-
-persistent_client:
------------------
-persistent_client [-d] [-x] [-f <Server_ior_file>] [-k file://<ior_output_file>]
- [-w] [-h] [-v]
-
-Options:
--------
--d Debug flag
--x Tells the server to shutdown at the end of the test.
--f Reads the server ior from the file
--k IOR or The IOR can also be given in the format like file://[file.ior]
- with the full path
-
--w Width of the grid from where the values are to be read
--h Height of the grid from the where the values are to be read
-
-run_test.pl:
-------------
-
-This perl script runs the server then the client. It shuts down the
-server and restarts the server. It then starts the persistent_client
-to read the values from the memory mapped file.
