Answer / bala

Isolation by its name explains the level by which two or more concurrent transactions are isolated from each other to maintain the data integrity in the database.

for example transaction A and transaction B are concurrent transactions, then it defines if A can read/update the data being modified by B or not and vice versa.

These Isolation levels will be used based on the business logic.

i know the stpes 2 create an executable CICS/DB2 cobol code. 1. DB2 Precompiler converts the SQL Statements into COBOL API statements and creates another member with Acess plans. CodeA results in CodeB (code with API calls) & CodeC ( Access Plans ) 2.Code B is compiled/linked 2 create an exceutable.(codeE) 3.Now CodeC is binded to the database on which CodeE will be run. Can somebody provide me the sample JCLs for precompile/compile/link/bind.
