BCV5 TM FAST AND EFFICIENT DB2 DATA MIGRATIONS

BCV5 TM FAST AND EFFICIENT DB2 DATA MIGRATIONS Corporations maintain large amounts of data in DB2 databases, and it is normal to fi nd several DB2 subsystems for production, test and development. Refreshing testbeds from production systems is a vital part of development, testing and quality assurance life cycle. Obtaining relevant test data requires copying from one DB2 subsystem to anor. The window of opportunity for copying or migrating DB2 data is constantly decreasing as demands from 24x7 operations are increasing. Limited resources and shrinking batch windows make data delivery to QA diffi cult. CV5 quickly and effi ciently copies, refreshes and B replicates DB2 objects. BCV5 copies DB2 databases or tables within same or different DB2 systems. When measured against conventional copying methods, BCV5 saves around 90% on elapsed copy time and resources consumed (SSU, SRU). For one customer a ten-hour unload/load process was reduced to slightly over one hour. A BCV5 copy task integrates both physical data movement and DDL related requirements. It copies DB2 data, i.e. databases or tables with or without auxiliary objects indexes, views, triggers, procs and runstats. BCV5 automatically handles OBID translation and RBA adaptation. Copy jobs are completed in minutes rar than hours. DBAs are no longer forced to wait for weekend time slots and are able to run copying jobs on regular weekday shifts. Test data on demand is a dream come true for QA, development and test staff. BCV5 offers relief where need is greatest. It signifi cantly cuts down runtime and cost. It reduces CPU consumption by 90%+ and shortens preparation lead time required by staff. Automation Reduces Manual Effort and Keystroke Errors BCV5 is a completely automated expert system. The integrated ISPF interface allows copy process to be easily defi ned. Specifying select/exclude patterns identifi es objects to be copied and appropriate processing options. BCV5 s powerful renames mask facility makes adhering to naming conventions during target DB2 system a simple and error free task. A BCV5 copy process executes eir under control of product or an in-house scheduler. Once copy process is started re is nothing else to do. BCV5 automatically generates DDL for selected objects/ databases using specifi ed target names. It executes DDL in target DB2 environment, tailors respective JCL and generates required statements for copy utility. What if target objects already exist? BCV5 still automates everything. It is an expert system with a comprehensive check facility that ensures that target DB2 objects match source objects. Structural differences are detected and successful completion of copy process is guaranteed. Flexible Selection of Image Copies BCV5 permits copying directly from tablespaces or a set of image copies. Its fl exible selection facility allows choosing image copy (set) to copy from. Using latest, a specifi c generation or dated image copy is easy and straight forward. It identifi es right image copy datasets and pulls m into copy process. 1 5 UBS Hainer GmbH

Benefits Automates DB2 Cloning/Migrating/Refreshing Saves 90% CPU resources and run time Eliminates manual efforts freeing up technical staff Reduces overtime work and manual intervention Integrates seamlessly into IT environments Eliminates RUNSTATS, Rebuild Index, etc. Reduces DASD space required for direct copying RUNSTATS Cost Time and Money DB2 s optimizer needs valid RUNSTATS data to fi nd effi cient access paths. The RUNSTATS utility is known as a long running CPU hog. BCV5 eliminates costly RUN- STATS executions. Its copy statistics feature extracts current RUNSTATS from source environment and loads m into target in seconds. It is no longer necessary to wait for hours while RUNSTATS fi nishes running. Why is BCV5 so fast? BCV5 copies data at page level using a proprietary high performance copy utilty. While UNLOAD/LOAD process slowly extracts single rows one at a time, BCV5 copies complete page over to target and replaces DB2-internal OBIDs with respective target values. BCV5 also uses parallelism as a performance enhancement technique. It operates in a multi-thread mode and copies ten to eighteen tablespaces or tablespace partitions in parallel. This alone makes it up to ten times faster than DSN1COPY. One or performance enhancement feature involves copying indexspaces. Copying indexspaces is much faster than rebuilding m. How can BCV5 save 90% CPU Time? Row-wise processing consumes many more CPU cycles than VSAM copying. Clients report that only one-fi fth to one-tenth of service units used by Unload/Load are required to run BCV5. Add to se savings those resulting from avoiding index rebuilds and runstats executions. LOADs demand heavy DB2 subsystem resources. The load job s CPU consumption is reported in job listing, but very high service units used by DB2 is no normally tallied. The immense amount of data, that corporations need to maintain, demands use of effi cient tools. It is not longer feasible to waste time and service units needlessly. There is an added bonus for users with really large tables. BCV5 does not require storage for unloaded data. BVC5 copies data directly from source pageset to target pageset. Making Copy Process Easy A fast and effi cient cloning tool is only part of solution. The BCV5 user interface is intuitive and easily meets needs of both experienced effi ciency-minded experts and less technical application level users. Those who prefer PC environment can use BCV5 s graphical workstation. Detailed online help is always one click away. Who needs BCV5? Cost savings are obviously appreciated by those who have budget responsibility. Avoiding an expensive and onerous hardware upgrade can reduce negative impact to an IT budget. The IBM and third party software upgrade fees associated with getting a bigger machine often dwarf hardware cost. Application development teams, QA groups, technical support staff, auditors and, of course, end users need data to get ir jobs done. BCV5 reduces 2 5 UBS Hainer GmbH

» BCV5 allows us to copy much more data than we ever could have copied with our old LOAD based processes. This is great improvement for our QA environments. «Checks and/or generates DDL Automates tasks for: OBID, RBA, LRSN, Grants, etc. Flexible space allocation Offers intuitive ISPF interface for easy management Provides a batch interface to create large numbers of copies Offers optional components for data reduction, data masking, and DDL structure analysis amount of weekend and off-shift time usually required for copy and refresh process. This allows more quality work to get completed during regular shift hours. Shops running with reduced or less experienced staff are among BCV5 s most vocal supporters. Getting job done is, after all, true mission of IT. When data is not available, job does not get accomplished and whole organization pays price. A Quick View of BCV5 BCV5 provides fast, effi cient and manageable copying of DB2 data. It automatically generates and executes jobs to: extract object defi nitions from DB2 catalog of source system, transfer defi nitions to target system, rename objects as specifi ed and apply m in target DB2 system (CREATE, or DROP and CREATE), compare source defi nitions with existing target objects for compatibility, copy pagesets from source to target DB2, make target objects ready and start m. The product provides two user interfaces with identical functions. One is based on ISPF and or on a workstation GUI. To defi ne a copy task, select and d efi n e: DB2 subsystems, source and target which are identical if copying within a single subsystem, objects: databases or tables to be copied, renaming rules to copy objects, wher indexes are to be copied, wher related RUNSTATS should be transferred to target system catalog, wher or related objects (GRANTS, BINDS, VIEWS) should also be transferred, wher source objects should be put in "read only" mode during copy, wher BCV5 should be used to avoid impacting source objects. Once a task is defi ned it may be executed at any time under BCV5 s control or under shop s scheduler or manually on a stage by stage basis. User creates a copy task using ISPF or Workstation or Batch Interface Source DB2 Extract meta data from DB2 Catalog Set objects read only option optionally Copy Pagesets or Imagecopies BCV5 Task Definition and Execution Target DB2 Check, amend, add DDL Make objects ready and execute objects BCV5 Workflow 3 5 UBS Hainer GmbH

» With BCV5 we have been able to reduce our batch processing cycle by 2 1/2 hours and are meeting our SLA commitment for reporting database for first time ever. «Optional Components BCV6 In-Flight Cloning When data must come from tables that require 24x7 enterprise availability re is an issue for IT. Users need to query and update tables without interruption. Stopping source objects is not a viable option. Without stopping source objects, it can be very diffi cult to copy tables while preserving consistency between tables and indexes and between different tables. BCV5 minimizes copy time, but cannot avoid impact of changes made to objects while y are being copied. The good news is that DB2 stores information about all se table changes in its log. BCV5 is an automated solution that uses information in log to bring copied tablespace to a consistent state. RM Reduction and Masking Data privacy regulations impact how test centers use production data. Providing production data for testing purposes requires that database administrators do not copy data directly without fi rst masking sensitive data fi elds. RM modifi es sensitive data during copy process following user specifi cations. RM provides a selection of masking methods and supports user algorithms making this process fl exible and powerful. At same time that sensitive data fi elds are being protected, RM also allows data reduction to take place. It supports using fi ltering criteria to select subsets from source data. This is particularly useful for unit and regression testing where only certain data is needed from a large data source. IB Icebox Archive DB2 data and populate different environments. Need to provide DB2 data from last week, last month or last year? Want an automatic and effi cient procedure to recreate everything, DDL and data in record time? IB takes fast snapshots on demand or periodically, and restores objects or databases where/when needed using names specifi ed. Issues of compatibility or completeness no longer cause concern. BCV5 IB packages DB2 Version x imagecopy and later restores it to any or DB2 target version required. Upgrade to a newer version of DB2 knowing that former image copies will be still available for future needs. RC Remote Copy Some production systems are to such an extent physically isolated that it is extremely diffi cult to migrate data effi ciently to test systems: separate sysplex neir shared DASD nor bridging volumes with or systems. The RC component of BCV5 makes data transfer between isolated systems an easy task. RC uses TCP/IP to transfer tablespaces, indexspaces as well as meta data from one system to anor. The entire cloning process is automated, error prone manual interventions are avoided. BI Batch Interface BI eliminates need for most manual procedures. It supports effi cient use of batch processing to enhance throughput. It provides a powerful defi nition language for using all of BCV5 s features and functions in a simple and fl exible way. The Batch Interface function is best way to implement mission critical trigger processes that require integrity, reliability and performance. It is interface to BCV5 to defi ne and control copy tasks by your own applications. 4 5 UBS Hainer GmbH
