Middleware Interview Questions2 - Middleware News

7. What are the different categories of client/Server applications?
Classes of client/server applications: Client/Server applications can be categorized by class,
based on where most of the processing is done. Each class requires different hardware and
software capabilities on the client, the server and the network.
1. Host-Based Processing
2. Client-Based Processing
3. Coopeartive Processing


8. What is meant by Client, Server & Network?
Client : The client hardware is the desktop machine that runs client software. It could be a micro
or a workstation. The client software formulates data request and passes the request to the
network software. This software sends the request to the server, accepts the result from the server
and passes the request back to the client software.
Server : A server is the machine that runs data management software that has been designed for
server functionality. A server has operating system software, data management software and a
portion of the network software.
Network : The network hardware is the cabling, the communication cards and the devices that
link the servers and the clients.

9. Define Application server.
Application Server : Application server, which provides specific application services to an
application. Application servers are the type of middleware, which occupy a large chunk of
computing territory between database servers and end users.

10. What is meant by HTTP and ODBC?
1. ODBC : Open database connectivity is a windows technology that lets a
database client application connect to a external database. To use ODBC,
the database vendor must provide an ODBC driver for data access.
2. HTTP : Hyper Text Transfer Protocol is the underlying protocol used by
the world wide web. HTTP defines how messages are formatted and
transmitted and what action web servers and browsers should take in
response to various commands. HTTP only supports transmission of text.

11. Define Group Server.
Groupware Server : A Groupware server is a software designed to enable users to
collaborate, regardless of location through the internet or a corporate intranet and to work
together in a virtual atmosphere.

12. Define TCP/IP and IPx/SPx.
TCP/IP : Transfer control Protocol and Internet Protocol.

Adding SSL certificates to a mixed z/OS and Unix queue manager environment - Middleware News

Adding SSL certificates to a mixed z/OS and Unix queue manager environment - Middleware News 1. Security Considerations IBM advises customers who are using SSL, that the most secure way to do this is to use recognized Certification Authorities to sign their certificates. Ensuring secure transfer of information is the main purpose of SSL. This integrity must be properly observed when setting up SSL. You should always be certain who has signed each of your SSL certificates, who has had and who continues to have access to them. The first secure way to generate certificates is to generate a certificate request, on each system or machine that uses SSL. This request has to be signed by an external Certification Authority before it can be used. Getting certificate requests signed by a CA is secure, because during the signing process at no point do any files contain the certificate's Private Keys. This principle is vital to SSL security. Signing certificates in this way is covered...
