Db2 for mainframe z os is a relational database management system that runs on the mainframe.a relational database is a database in which all of the data is logically contained in tables. these databases are organized according to the relational model.
Sql Commit Rollback Statements Reintech Media The commit statement commits the database changes that were made during the current transaction, making the changes permanent. db2 holds or releases locks that are acquired on behalf of an application process, depending on the isolation level in use and the cause of the lock. In db2, the rollback statement reverses all modifications made to the database in the current transaction. it’s particularly useful in multi step transactions where an error or problem in one step requires reversing all changes to avoid inconsistencies. Db2 returns status in the sql communication area (sqlca), and the program uses commit and rollback to control transactions. this tutorial introduces db2 on z os, the basics of embedded sql in cobol, host variables and sqlca, and the difference between static and dynamic sql.

Without a commit, changes remain in a temporary state and can be undone by issuing a rollback statement, which reverts the database to its state before the transaction began. If a commit or rollback statement in a stored procedure violates any of these conditions, db2 puts the transaction in a must rollback state. also, in this case, the call statement fails. Code an explicit commit or rollback statement at the end of an application process. either an implicit commit or rollback operation will be performed at the end of an application process depending on the application environment. Db2 is built on an intelligent common sql engine designed for scalability and flexibility. in this mainframe tutorial we discussed some of the important concepts of db2.
