50 BMC Mainframe Innovations – System/390(R) Period (1990-2000)

The mainframe faced two crucial challenges in this time: 1) the cost of mainframe computing power (MIPS) was under pressure from distributed computing; 2) the monolithic application model was being replaced by n-tier client/server computing.  Mainframes responded to the former with the introduction of CMOS technology and substantially cheaper MIPS.  For the second challenge, the mainframe, with its twenty plus years of development, housed critical business logic and data, and became the key source of the information that end-users wanted to access.  Organizations created application structures that resulted in their customers engaging with the mainframe, even though they likely did not recognize they were doing so.


IT attention had to shift to the end user and managing quality of service, and BMC innovations pioneered new systems management techniques along with improvements in their solutions that resulted in even more mainframe availability.


BMC Innovations that Changed Mainframe Management (1990 – 2000)

(Watch this blog in coming weeks for reminiscences about these innovations.)


1999 – MainView Explorer delivered browser- based real-time monitoring of mainframe performance without the need for outboard hardware implementations

1999 – APPLY PLUS for DB2(R) offered an extremely fast STATIC SQL processor as an alternative to free DYNAMIC versions

1998 – Recover Plus for DB2 (Recover Backout) was the first alternative way (using backouts) to recover from DB2 data base errors

1998 – Fast Path Online Reorg & Image Copy provided faster method for reorganizing IMS(R) DEDB data bases while data is still online

1997 – Reorg Plus for DB2 SHLEVEL CHANGE Allowed full update ability to a tablespace during 99% of the REORG process eliminating the need for application outage

1995 – DATA ACCELERATOR Compression compressed data to improve performance of applications using the data

1994 – APPLICATION RESTART CONTROL for DB2 and IMS automatically manage batch job failures and restarts

1993 – XBM (Snapshot Upgrade Facility) was the first product to take advantage of software caching and intelligent hardware to reduce the COPY time and outages

1992 – Change Manager for DB2 automated and simplified schema management for DB2

1992 –  ULTRAOPT reduced loading on networks to improve performance without having to add network bandwidth

1991 – Recover PLUS for DB2 offered a faster time to recover from DB2 data base errors

1991 – LoadPlus/UnloadPlus for DB2(R) provided a faster method for loading/unloading DB2 tables

1990 – RECOVERY PLUS for IMS(R) delivered a faster time to recover from IMS data base errors
