Question

Where is application and service configuration information stored on Unix and Linux systems? In Windows? Compare and contrast the two in terms of security, accessibility, and automation.

Answer 1

Configuration attributes are held in configuration files, at the level of the node and of the queue manager.

Client configuration options are held separately, in the client configuration file.

A configuration file (or stanza file) contains one or more stanzas, which are groups of lines in the .ini file that together have a common function or define part of a system, such as log functions, channel functions, and installable services.

Because the IBM WebSphere MQ configuration file is used to locate the data associated with queue managers, a nonexistent or incorrect configuration file can cause some or all MQSC commands to fail. Also, applications cannot connect to a queue manager that is not defined in the IBM WebSphere MQ configuration file.

Any changes you make to a configuration file usually do not take effect until the next time the queue manager is started.

On Windows and Linux (x86 and x86-64 platforms) systems, you can edit configuration information from the IBM WebSphere MQ Explorer.

comparison between unix and linux

criteria	unix	linux
security	unix takes more time to deal with bugs and threats as compared to linux. UNIX operating systems comes with its own firewall product	linux is more responsive and fast in dealing with threats and security issues. Linux comes with open source netfilter/iptables based firewall tool to protect your server and desktop from the crackers and hackers
accessibility	Unix operating systems were developed for specific purpose designed mainly for mainframes, servers and workstations and it is not freely available.	It is user friendly open source software freely available on the internet.Everyone including home users to developers and computer enthusiasts can use it.
automation	In text mode interface,Originally the Bourne Shell. Now it's compatible with many others including BASH, Korn & C.	In text mode interface, BASH (Bourne Again SHell) is the Linux default shell. It can support multiple command interpreters.
