EXPRESS MQ IMPORTER/EXPORTER
“We can use both FTP and MQSeries. Which one….?”
Such questions and answers to them abound on Internet.
“FTP is synchronous - it requires both ends to be available at the time of transmission. MQ is asynchronous.”
“FTP does not provide any restart/resume capability for interrupted transfer (no checkpoints).”
”FTP has no in-built ability to re-retry a file transfer if the other end is down.” ……
And, many more, mainly in favor of MQ, which accounts for the increasing use of MQSeries in tasks where, traditionally, FTP has been used.
The arguments in favor of MQSeries can be best summarized in a sentence that floats around Internet:
“FTP will leave the data by the door, but MQ will knock on it, and hand deliver it to the customer. "
And, FTP has one major advantage: It is simple!
EXPRESS MQ IMPORTER/EXPORTER(EMQIE) claims to bring enormous simplicity to one area of MQSeries: Interchanging Data between MQSeries Queues and flat files (QSAM datasets).
Usually, applications related with each queue require new programming and new JCLs, for the attributes of queues and datasets would vary (Queue Manager/Queue Names, Message Lengths, Dataset Names, Formats, Record Lengths, etc.).
With number of experienced programmers in the area retiring, with the depth of expertise needed in mainframe environments, the cost of development is steadily increasing.
EXPRESS MQ IMPORTER/EXPORTER(EMQIE) obliterates the need of program and JCL development in the area it claims to bring a solution. It does not require any syntax knowledge for its own usage.
WHAT IS EXPRESS MQ IMPORTER/EXPORTER(EMQIE)?
EMQIE is a Zero-Programming, Zero-JCL mainframe productivity tool that can be used to insert data into or to extract data from MQSeries Queues.
IMPORT refers to the function whereby the contents of a flat file (QSAM dataset) are transferred into an MQSeries Queue; whereas EXPORT refers to the function whereby the contents of an MQSeries Queue is transferred into a flat file (QSAM dataset).
WHAT ARE THE FUNCTIONS OF EMQIE?
2 main and 4
unto an MQ Series
The tool DOES NOT NEED to be given the attributes of the input dataset (fixed/variable size record formats, record length, etc.), nor the attributes of the MQSeries Queue, for the tool has the intelligence to determine them.
Under TSO, call EMQIE, which brings the following screen:
1. Queue Manager Name,
2. Queue Name,
3. The info related with one of the Directions: either,
3.1 “From Dataset to MQ” with input Dataset Name, or
3.2. “From MQ to Dataset” with output Dataset Name and instruction on whether or not MQ records are to be kept in the queue.
And, press F6, which will issue a JOB to perform the task requested.
Optionally, you may use F7 or F8 to Edit Input or Output Dataset.
The batch job, besides performing the Import or Export task, produces a report summarizing the task performed,
FROM THE QUEUE)
The report may also have an error description that may have been detected, such as:
