Populating Current USERID in CICS (COBOL) map filed is the most common requirement for the Update-able Maps. Along with USERID, getting Current date-time are also can be retrieved using the CICS supplied commands. These can be coded in COBOL program under EXEC … & END-EXEC just like any other commands. ASSIGN USERID – ASSIGN command
These Questions have been asked in Cognizant(CTS) for Mainframes Technical round of Interview. CICS & VSAM–> What is the MAX size of COMMAREA? What happens if we try to send the data with size more than 32k? While passing data between two programs(PGMA TO PGMB) using COMMAREA. If in PGMA The commarea size is 30
Scrollable cursors are introduced to overcome the limitation of reading the result table in sequential order.In Normal cursors, the cursor places at the first row of the result set when OPEN cursor statement is executed. And for each Fetch, the cursor gets moved by 1 row forward in the result table and this is the
Handling Null Values in COBOL DB2 program is an important aspect without which program may get into erroneous status. Null is nothing but no value has been populated or Value is missing for that DB2 table column.In other words, few columns gets populated only based on certain criteria, if it meets that criteria then it
Multi dimensional arrays in COBOL are supported and it is possible to have up to 7 dimensions which is its MAX limit. But more than two dimension array creates confusion.So in general two dimensional arrays and Single dimensional arrays are used mostly. Let us see how to declare and process multi dimensional arrays in COBOL.
At Rimini street, they use micro focus COBOL that are used in Peoplesoft modules. So their main focus would be on COBOL. Knowing people-soft and SQLSERVER is an added advantage. What are the mandatory Divisions? Name different Divisions ? What are the different picture clauses? Difference between Comp and Comp-3 How to declare arrays? What
This SORT example is to add Header and Trailer to the sorted file along with the total number of records. Header –> A Name along with the current System date Trailer–> A static message along with number of input records count Example Sort Card: [crayon-5d876cc4f15bf784991070/] Header1 –> It has a Static message which start from
JCL Trick to write the output file in reverse order of input using SORT. If the input file has some records in Random order ( not in sorted order) and if the out file needs to be written exactly in reverse order. This can be achieved by using the SORT Overlay along with OUTREC BUild.
What is a MAP? It is a screen representation of a functionality from where users can access(to perform different functionalities) it. In other words it is nothing but the front end for the mainframe applications. Example -> A Bank Customer Inquiry Screen from where the bank employees/Users access customer details by entering the Customer number
JOBLIB and STEPLIB in JCL both are used to specify the load libraries so that that the programs that are being used in that JCL/JOB are searched in these libraries. Generally z/OS searches for the programs load module in the default system libraries where actually the IBM supplied programs are stored. Specifying JOBLIB/steplib makes the
