What is IBM MQ and its responsibilities?
- Mq stands for message queueing.
- Ibm mq depends on a message lining innovation and empowers application projects to speak with one another by sending or accepting messages across an organization of divergent stages utilizing an application programming interface called mqi.
What do you know about the message-driven process?
- At the point when a message shows up on a line, they can naturally begin an application utilizing setting off.
- On the off chance that vital, the applications can be halted when the message (or messages) have been handled.
What are the advantages that corporate can have through ibm websphere mq ?
- Asynchronous
- Platform independent
- Security
- Integration
- Assured delivery
How MQ supports integration?
- Mq is autonomous of the working framework which you use for example It may be windows, solaris, aix.
- It is also independent of the protocol (i.e. Tcp/ip, lu6.2, sna, netbios, udp).
- It isn’t needed that both the sender and beneficiary ought to be running on a similar stage
What do you mean by asynchrony in IBM WebSphere MQ?
- With message lining, the trading of messages between the sending and getting programs is free of time.
- The sender can keep preparing without trusting that the beneficiary will recognize receipt of the message. The objective application doesn’t need to be running when the message is sent from sending end of the application.
- It can recover the message after it is having been begun.
What is a message and what does it contain?
- A message is a series of bytes that is significant to the applications that utilizes it.
- Messages are utilized to move data starting with one application program then onto the next (or between various pieces of a similar application).
- The applications can be running on a similar stage, or on various stages.
How might be the message structure in ibm mq ?
- The application information: The substance and design of the application information is characterized by the application programs that utilization it.
- A message descriptor: The message descriptor recognizes the message and contains extra control data, like the sort of message and the need doled out to the message by the sending application. Websphere mq characterizes the organization of the message descriptor. For a total depiction of the message descriptor.
What is queuing and queue?
- Lining is the component by which messages are held until application is prepared to deal with them.
- Line is an ibm mq object to store messages which should be traded among sending and getting end of the application.
- In spite of the fact that you can build this to a most extreme length of 100 mb (where 1 mb approaches 1 048 576 bytes)
What is the maximum length of the message does mq support?
- The default most extreme message length is 4 mb.
- In spite of the fact that you can expand this to a most extreme length of 100 mb (where 1 mb approaches 1 048 576 bytes).
What is the contrast among industrious and non-diligent messages?
- In WebSphere MQ, messages can be either tireless or non-determined.
- Tireless messages are logged and can be recuperated in case of a websphere mq disappointment. In this way, industrious messages are destined to be conveyed.
- Nonpersistent messages are not logged and can’t be recuperated in case of mq disappointment.
What is the effect of using persistent messages?
- Persistent messages are usually logged. Logging messages lessens the presentation of your application, so utilize constant directives for fundamental information as it were.
- In the event that the information in a message can be disposed of if the line chief stops or fizzles, utilize a nonpersistent message.
What is mq server?
- A web circle mq worker is a line administrator that gives lining administrations to at least one customers.
- All the web circle mq objects, for instance lines, exist just on the line director machine (the web circle mq worker machine), and not on the customer.
- A web circle mq worker can likewise uphold nearby web circle mq applications.
What is MQ client?
- A web circle mq worker is a line chief that gives lining administrations to at least one customer.
- All the web circle mq objects, for instance lines, exist just on the line supervisor machine (the web circle mq worker machine), and not on the customer.
- A web circle mq worker can likewise uphold nearby web circle mq applications.
What are the articles utilized in web circle mq?
Queue manager qqueues qchannels qprocesses qname lists
Notice the no of characters needed for making names of the mq objects?
For mq channels it is 20 characters qfor remaining articles it is 48 characters.
Shouldn’t something be said about is the default port number for mq line chief?
Default port number is 1414
Difference between mqsc commands and control commands?
Mqsc orders: these orders are utilized to deal with the administrator related capacities for the segments that are available in the mq arrangement. Overall mqsc orders are utilized for making and keeping up message channels, line directors, bunches and so on
Control orders: these orders are utilized to deal with the cycles and administrations that are useful in the working of the mq arrangement. Overall these orders are utilized for channel audience, channel initiator, trigger screen and so on
Is the mqsc attributes are case sensitive?
- Mqsc orders, including their characteristics, can be written in capitalized or lowercase. Item names in mqsc orders are collapsed to capitalized (that is, line and line are not separated), except if the names are encased inside single quotes.
- In the event that quotes are not utilized, the item is handled with a name in capitalized.
What is the order utilized for beginning the line supervisor?
Strmqm qmname
What is the order utilized for halting the line administrator?
- Endmqm -w qmname
- The command waits till application to be stopped completely and will stop the qm
- Endmqm –i qmname
- This sort of closure doesn’t trust that applications will separate from the line administrator.
What’s the message code for halting a line administrator?
Amq4044 queue manager stopping
What is the command used to delete the queue manager?
Dltmqm qmname
Display the attributes of the queue manager qm1?
- Runmqsc qm1 • display qmgr
What is a programmable command format (pcf) commands?
- These orders are given from a program for nearby or distant organization done by software engineers.
What is line supervisor in ibm websphere mq ? What does line director do?
- Queuemanageris essential segment of websphere mq or wmq
- The line director is liable for putting away and steering messages to other line chief inside mq and it likewise speaks with outside world for example Java program or some other mq customer.
What is direct in ibm websphere mq?
- In websphere mq or wmq, line director use channel to communicate messages to other queuemanager.
- Channel conveys one path traffic in mq arrangement (for example Channels are uni directional). You can have either sending divert or accepting direct in mq.
What is distinction between dead letter line and backout line in websphere mq?
- Dead letter line is utilized to store messages which is gets for non-existent line.
- In the event that mq arrangement not ready to convey message to customer after a preconfigured endeavor, wmq moves message to backout line.
What is triggering in ibm mq?
- Websphere mq can begin an application naturally when certain conditions on a line are met.
- For instance, you should begin an application when the most extreme number of messages on a line arrives at a predefined number.
What is the contrast between a nearby line and distant line in wmq ?
- In WebSphere MQ, nearby lines are line on a similar line director.
- While far off line alludes to a line on various line supervisor.
What are the different logging methods available?
- Roundabout: the roundabout logging is utilized for restart recuperation. It is the default logging technique. Round is utilized being developed and testing lines. Roundabout logging keeps all restart information in a ring of log records.
- Direct: straight logging gives you both restart recuperation and media recuperation. It is utilized underway. Straight logging keeps the log information in a ceaseless grouping of documents.
