But even with this robust set of features, many companies now face pressure to modernize their business applications beyond the scope of what CA 2E can offer. The challenge is to move forward without discarding the decades of investment in design and evolution stored in the CA 2E model. View Datasheet Contact an Expert A Truly Modern Architecture Automated transformation into modern languages enables more agile systems and better maintainability. It also makes it easier to bring on new skillsets, leverage open source technology, plug into devops solutions, integrate seamlessly with applications and take advantage of the cloud.

Journaling and Commitment Control processing is a means of automatically grouping a number of database updates into a single transaction for the purpose of recovery: either all or none of the updates will take place on files. We have to first create the journal using crtjrn and the crtjrnrcv journal receiver add the file on journal receiver and then set the commitment control.
In the Edit Function Options section. What are the values for controlling whether or not a program is run under commitment control?
M Master — Program is run under commitment control, program is controlling program and contains commit points. S Slave — Program is run under commitment control; however, the commit points are in another program.
N None — Commitment control does not exist in this program. Scenario Questions Size exceeding so and cant compile so how will u fix it? What does Rtvobj do? Is it an External or Internal function? How many user points does it have? Int function. When will User Point Exit Processing get executed? Whenever data record is found. When data record is not found and there is empty not even comment code in User point Data record not found.
What can we do to Surpass other? So no need to pass the field values. If we are changing the Parent file? Do we have compile the child files? Yes Only screen functions. What is public and Private Change?
This is public change and any recompile due to internal function change is private change. How many Subroutines will be declared and how will it work? It will be declared only once. Key values will be moved to work variable before calling the Subroutine and this Work variables will be moved to DB fields inside the Subroutine.
If you have retrieve object their you have two output variables in parameter list and in you functionality you do not want second output variable. What will you do, you will create one more retrieve object or any other solution? Ans: Instead of creating new retrieve object you can use the same one, the one output variable which you do not want make it as NLL.
Referential integrity between the entities is built into the functions built over the entities. Select Record functions are automatically built to provide F4 or?
You only wish to get the first record in a file, How? How would you design a batch function for updating records? Use an Execute External function type which has a Retrieve Object in it then, once a record is read, use a Change Object to update the record.
The Retrieve Object can be omitted if the Change Object is to handle reading and updating the same file. How would you design a batch function to print a report for a given range of dates? Call a CL program which will call a Prompt and Validate function to fill in the record selection parameters.
List all the alternative ways for putting several variables into one field. When to use it? Quit is a built—in function that exits from an action diagram sequence construct. It has no parameters and returns control to the calling sequence construct. When you want to quit processing if a certain condition exists ie. Do not perform update processing if errors occurs on the validate processing. Processing in the program will proceed to the exit point of the function that called the Execute Internal Function.
Use a Display File in place of the Select Record function. What does ELM mean and where is it used? ELM is the element context of an array that helps to substring the value of field to different array fields.
Mostly used to concatenate and split fields. Share this:.
Its products continue to be widely used in that sector today, distributed and supported by CA Inc. In the same year the company appointed its first overseas distributors, in Australia and Norway. Synon also established a worldwide distribution channel with subsidiaries in France , Germany , Australia , Hong Kong and Japan. IBM later acquired an equity stake in Synon. As a condition of the transaction, Synon moved its HQ to Larkspur and became a Delaware corporation, changing its name to Synon Corporation. In Williams and Horton sold Dysys to Synon, and returned to the fold.
