Thanks. We'll let you know when a new response is added.

We think there is a future for AS/400/i-Series programmers.
We love the system, it’s solid and reliable.

In the US the number of installations and jobs seems to have stabalized.

    I agree that the need for skilled AS/400, iSeries, System i, IBM i professionals will start growing more and more as IBM combines the hardware and starts pushing the IBM i operating system. Also adding to that are the number of developers that are nearing retirement and the general lack of IT students enrolling in colleges around the country not just on IBM i. IBM is calling it the "Perfect Storm" so I would encourage anyone getting training on the IBM i to keep with the platform as more and more opportunities will open up within the next 5 years and salaries will continue to climb and outpace the rest of the job market. Remember back to the days of the mainframes and the Cobol programmers that were let go in the 80's. Now you are paying big big dollars for mainframe Cobol programmers. Besides with the many facets of the IBM i and all of the still far superior things it can do and do well, why would anyone leave :-)

    Hi DB2 experts, How different is DB2 for AS/400 and for mainframe? For example, relating to the high-level DB2 administrative privileges. Catalog names such as SYSADM, SYSCTRL, SYSOPR, DBADM, PACKADM, DBMAINT, DBCTRL, or catalog views such as SYSCAT.DBAUTH, SYSCAT.COLAUTH, SYSCAT.TABAUTH etc, are they (naming) the same for both platforms (AS/400 and mainframe)? Thanks, Rauf

    Dwinginsih, DB2 on z/OS vs DB2 on 400 - similar, yet different. You mentioned SQLID / auths such as SYSADM & SYSOPR and these are VERY similar, almost identical. You mentioned catalog tables such as TABAUTH. The catalogs are similar and yet different. In a nut shell: the SQL is 98% plus the same RDBMS rules are same - theory, normalization, etc But the differences are significant: Z uses VSAM datasets (KSDS & Linear) and PDSes and started tasks and SMS and HSM and WLM and ... Like all things in this field, if you are going to be good at DB2 (or *any* software) you need a good understanding of the operating system. DB2 on any platform is similar. But where DB2 and the OS meet is where the differences come in.
