The scope, complexity, and pervasiveness of computer-based and controlled
systems continue to increase dramatically. The consequences of these sys-
tems failing can range from the mildly annoying to catastrophic, with serious
injury occurring or lives lost, human-made and natural systems destroyed,
security breached, businesses failed, or opportunities lost. As software
assumes more of the responsibility of providing functionality and control in
systems, it becomes more complex and more significant to the overall system
performance and dependability...
Shared server processes are utilized in the shared server architecture. Figure 5–8 on
page 5-10 depicts a shared server architecture. With shared server architectures, client
processes ultimately connect to a dispatcher. The PMON process registers the location
and load of the dispatchers with the listener, enabling the listener to forward requests
to the least loaded dispatcher.
A dispatcher can support multiple client connections concurrently. Each client
connection is bound to a virtual circuit.
The listener receives client connections and evaluates against a set of rules whether to
deny or allow access. If it allows access, the listener forwards a request to a gateway
process, selecting the one with the fewest connections. The CMGW process, in turn,
forwards the request to another Oracle Connection Manager or directly to the database
server, relaying data until the connection terminates. If a connection to the server
already exists, the gateway multiplexes, or funnels, its connections through the
Household finances and attitudes also bear heavily on the housing market, which
has generally remained depressed. In particular, home sales dropped sharply following
the recent expiration of the homebuyers’ tax credit. Going forward, improved
affordability--the result of lower house prices and record-low mortgage rates--should
boost the demand for housing. However, the overhang of foreclosed-upon and vacant
housing and the difficulties of many households in obtaining mortgage financing are
likely to continue to weigh on the pace of residential investment for some time yet. ...
Wheelchair Warrior tells the true story of Melvin Juette,
an African American gang member from Chicago who
was shot and paralyzed and later became a world-class
wheelchair athlete. It is not primarily a story about urban black America,
although it is also about that; rather, it is a story that focuses on
Juette’s resiliency in the face of his disability and how his involvement
in wheelchair basketball helped him move forward with his life.
The strong recovery in net private capital flows to emerging markets that began in 2003 has continued this year. Although a moderation in the pace of flows is anticipated in the next several quarters, the overall level envisaged for 2006 remains relatively elevated. Downside risks have increased, however, in the face of rising concerns and unease about a potentially less hospitable global economic environment going forward.
Notwithstanding some important steps forward, however, as we return once again
to Jackson Hole I think we would all agree that, for much of the world, the task of
economic recovery and repair remains far from complete. In many countries, including
the United States and most other advanced industrial nations, growth during the past year
has been too slow and joblessness remains too high. Financial conditions are generally
much improved, but bank credit remains tight; moreover, much of the work of
implementing financial reform lies ahead of us.
The international consequences of zero-interest-rate policies are also negative. With
interbank markets in the U.S. and Europe congested, forward foreign exchange markets become
more difficult to organize. Without forward cover, exporters and importers find it more difficult
to secure normal letters of credit. In the financial panic of 2008, foreign trade imploded much
more than domestic trade.
In addition, the Fed’s zero interest rate strategy inevitably weakens the dollar in the
The work undertaken by the Mental Health Commission since its
creation in the spring of 2007 by the Government of Canada, has
helped accelerate efforts across the country to redress this situation.
The publication of Toward Recovery and Well-Being marks an important
step forward not only for the Mental Health Commission but for people
everywhere in Canada.
We are enormously encouraged by the degree of support for the work
of the Commission to date and by the growing momentum for change.
