Match_merge_logic

MATCH - MERGE LOGIC Match Merge logic is extensively used in COBOL programs to compare the data in two sequential files effectively. Only pre-requisite to for using this logic is, all input files to be in Sorted Order Problem : I have 2 Sequential files File 1 and File 2 . If Record exists in both the files then write data into FILE A If Record exists only in File1 and not in File2 then write data into FILE B If Record exists only in File2 and not in File1 then write data into FILE C Solution: The effective way of solvi ng above problem is, by using Match Merge Logic. Only pre-requisite to for using this logic is, all input files to be in Sorted Order. First step sort I/P file Explanation of Logic : Below listed are I/P and Output files data for say RollNo File 1 File 2 FILE A FILE B FILE C 10

DB2-IMS - Few Difference

Cobol-DB2 Cobol -IMS 1 Need to Prcompile to generate 1. DBRM (Sql Staments only) 2. Cobol Object code No Precompilation Required 2 Bind the DBRM to Generate Plan. Plan consists of Executable SQL Quries No Bind Process is Required. Here we Write PSBs to fetch respective Record. 3 Compile Cobol Code Compile Cobol-Ims program 4 Execute Cobol - DB2 Program using IKJEFT01, where in we Specify Program Name and Plan Name to be Executed Execute Cobol-IMS program using DFSRRC00. Pass Program Name , PSB, Name, Plan name Thru Parm Parameter Why We need BIND In DB2 not in IMS Say below query is written in Cobol-Db2 Program Equivalent IMS Call 1 Select A, B, C First Define PCB to Fetch the field A, B, C Where A=10 Using DLI Call fetch the field A, B,

How to Solve SOC7 Abend - with screen shots

Below process helps to find out the statement, caused the SOC7 error. Check the Sysout of RUNJCL . This shows the error statement and lists offset value Take the Offset Value 000003C0 Got to respective Compilation Job listing, check the sysprint Search for the offset value 0003C0 (delete +00 -- initial 3 letters of Offset value and search for it) check below 2 screen shots This Offset value is listed under line no 0045 – which refers to Move statement. Take this no. 045 and find for it in same sysprint. This points to the exact statement, caused SOC7 T his 045 pints to the Move statement 1526, this is the exact line in the program Check for the above line no. In source program . This points to the statement highlighted below . Check the statement, variable check-4, which is added to check-6. These are having different Picture clause. check-4 is alfhanumaric, holding some junk data, when this data is moved to Chcek-6 variable(of comp-3) creates SOC7 error. This is just an example to e
