© 2008 Progress Software Corporation5 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Basic Steps Preparation Truncate BI, Disable AI, 2PC, and Replication (V9) Backup (V8/9) Install Install OpenEdge Don’t need to uninstall V8/9 *Don’t overwrite your current Progress Directory Upgrade Upgrade DB to OpenEdge 10 Do your backups !!!! Recompile/Re-deploy your ABL code if client is OpenEdge Run the Application and Test, Test and….. Test First detail plan, review plan, test plan THEN execute…
© 2008 Progress Software Corporation6 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 The Application Safe Install OpenEdge on your existing test machine proutil -C conv910* Recompile application* and test Fast and Loose Upgrade a remote or local client site Recompile application* and test The Rollout Upgrade remote systems with OpenEdge Remote client server, Remote Application servers “re-deploy” newly built application (PROPATH) and test * ABL code needs to be recompiled/re-deployed only when upgrading the client to R10. In 3-tier configurations (with AppServer™) the client could still be V9. Not possible via SQL or V8. * You will have to convert a V8 db to V9 before converting to OpenEdge

© 2008 Progress Software Corporation8 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Deployment Preparation Truncate BI Disable AI, 2PC, Replication (V9) Backup database (V8/9) Validate backup Install OpenEdge 10 on server machine And everywhere else! (Clients must be upgraded before the server can be) Recompile and re-deploy application (if need be) Client/Server V9 to OpenEdge 10 disallowed V9 Clients to R10 AppServer to R10 Database is allowed, No SQL V9 to OpenEdge permitted
© 2008 Progress Software Corporation9 Connectivity: Progress ® V9 and OpenEdge 10 ABL mixed configurations: Progress V9 and OpenEdge 10 are supported One version back (clients to servers) One version forward ( clients to Application Server ) SQL must match Refer to product by product information for further details Client Application Server Database NEW in OpenEdge 10
© 2008 Progress Software Corporation10 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Database Conversion Run conversion utility _proutil -C conv910 –B 512 Conversion runs in 5-minutes or less Basically just a schema upgrade No changes to user records or indexes No changes to physical structures Backup database Re-start database and application
© 2008 Progress Software Corporation11 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 You are now “Good To Go” with OpenEdge No physical changes to existing user data Data remains in Type I storage areas Data fragmentation exists as before Optimize physical layout when time permits...

© 2008 Progress Software Corporation13 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Storage Areas? Performance, Scalability & Maintenance Take advantage of new features No adverse application effects Physical reorg does NOT change the application Object location is abstracted from the language by an internal mapping layer Different physical deployments can run with the same compiled r-code
© 2008 Progress Software Corporation14 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 How to Get There Preparation (same as before) Truncate BI, disable AI, backup, validate, install… Before Physical Reorg Upgrade database to OpenEdge 10 –conversion utility –prostrct create (a must if changing block size) Physical Updates (no r-code changes required) Separate schema from user data Create new storage areas –Specify records per block –Specify Type II cluster sizes
© 2008 Progress Software Corporation15 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 How to Get There Physical Reorg Spread data out amongst new areas Move indexes Online options vs offline options Database block size changes are offline After Reorg Reclaim Unused Space –Truncate old data area –Delete old data area
© 2008 Progress Software Corporation16 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 How to Get There In Place (same database) Transformation done all at once or over time Add new storage areas to existing database Migrate data from old areas to new Reclaim space from old areas New database Transformation done in one maintenance window Dump old data Create new database Load into new database Prodel old database Mix of Option #1 and Option #2 (custom) Create new database Move data from old database to new database Reclaim space by deleting old database
© 2008 Progress Software Corporation17 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Getting started Separate user data from schema
© 2008 Progress Software Corporation18 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Moving schema tables Separate Schema from user data (in place): proutil -C mvsch (offline operation) Schema Area Old Default Area Renames existing schema area
© 2008 Progress Software Corporation19 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Moving schema tables Separate Schema from user data: proutil -C mvsch (offline operation) Old Default Area Schema Area Renames existing schema area Creates new schema area Moves schema Tables & Indexes Schema Area
© 2008 Progress Software Corporation20 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Moving schema tables Separate Schema from user data: proutil -C mvsch (offline operation) Old Default Area Schema Area Renames existing schema area Creates new schema area Moves schema Tables & Indexes Schema Area You move data To new areas User Area User Area User Area User Area You truncate Old Default Area
© 2008 Progress Software Corporation21 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Physical Changes: Location, Location, Location Create.st file with new layout Set records per block Use Type II Storage Areas Tables 64 or 512 block clusters Indexes 8 or 64 block clusters d “Cust/Bill Indexes“:7,1;8 /d_array2/myDB_7.d1 f d “Cust/Bill Indexes“:7,1;8 /d_array2/myDB_7.d2 # d “Customer Data“:8,16;64 /d_array2/myDB_8.d1 f d “Customer Data“:8,16;64 /d_array2/myDB_8.d2 # d “Billing Data“:9,32;512 /d_array2/myDB_9.d1 f d “Billing Data“:9,32;512 /d_array2/myDB_9.d2

© 2008 Progress Software Corporation23 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Moving Tables and Indexes 1.Table move and Index move Online (by primary index) 2.Dump and Load (D&L) With or without index rebuild Application must be offline Suggestion: Mix of option #1 and #2 1 st purge/archive unneeded data Table move small tables (number of blocks) D&L everything else 3 Options for Data Movement
© 2008 Progress Software Corporation24 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Option #1: Table/Index Move Advantages: Online (with no-lock access) Dump & load in one step Schema is automatically updated No object # changes to deal with Parallelism Disadvantages: Only No-lock accessible during move Moves but doesn’t “rebuild” indexes Too slow for large tables Changes are logged! –BI growth may be of concern Pros and Cons
© 2008 Progress Software Corporation25 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Table Move proutil -C tablemove [ owner-name. ] table-name table-area [ index-area ] Move/reorg a table by its primary index Move a table AND its indexes Preferred performance Fast for small tables
© 2008 Progress Software Corporation26 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Index Move proutil -C idxmove [ owner-name. ] table-name. index-name area-name Move an index from one area to another Does NOT alter/optimize index block layout Fast but does not “rebuild” indexes Online but changes to owning table blocked
© 2008 Progress Software Corporation27 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Option #2: Dump and Load Textual Data ASCII dump ASCII load Bulk load followed by index rebuild Binary Binary dump Binary load –With index rebuild –Followed by index rebuild Custom (Textual or raw) D&L with triggers Buffer-Copy / Raw-data-transfer / Export/Import Can be tricky, you may want help 3 Dump and Load Flavors
© 2008 Progress Software Corporation28 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Dump and Load General Strategy Create new database structure Add to existing DB New database Run tabanalys Dump table data sequence values, _User table Data definitions Dump definitions Modify storage area locations Load definitions Load table data Build indexes (if needed) [10.1C can specify pack] Run tabanalys Backup * If you have the disk space, creating a new db saves time

© 2008 Progress Software Corporation30 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Dictionary Data Dump Database Admin tool OR: run prodict/dump_d.p(,, ). Advantages: Fast and Easy Parallel No endian issues Disadvantages: 2 GB File size limit** Pre 10.1C Can’t choose dump order Have to dump entire table Must ensure no one changes table between D&L
© 2008 Progress Software Corporation31 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Using Binary Dump Advantages: Fastest and Easy No 2 GB file size limit No endian issues Can choose dump order (by index) Can dump table data in portions Multi threaded (10.1B) Can dump multiple tables concurrently (parallel) Disadvantages: Must ensure no table changes between D&L (unless using triggers as well)
© 2008 Progress Software Corporation32 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Binary Dump Specified proutil -C dumpspecified ‘field- value1 AND operator value2’ -preferidx 10.1B03 allows multiple values Switches table.field MUST be lead participant in index Valid operators: LT, GE, LE, GT, EQ -preferidx determines specific index to use -index, -thread are ignored Performance Threaded is preferred Can run in parallel with many unique values Cautions Avoid using descending indexes There is a risk of missing a range
© 2008 Progress Software Corporation33 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Binary Dump Specified Finding the median value define variable i as integer no-undo. define variable max-recs as integer initial 0 no-undo. define variable median as integer no-undo. for each mytable NO-LOCK use-index : max-recs = max-recs + 1. end. median = max-recs / 2. do i = 1 to median: find next mytable NO-LOCK use-index. end. display i substr(field1, 1, 192).
© 2008 Progress Software Corporation34 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Binary Dump Threaded proutil -C dump -index -thread 1 -threadnum -dumpfile -Bp 64 -index Choose index based on read order -index 0 –Faster dump, slower read –Assumes coming from Type II -thread indicates threaded dump # threads automatic (# CPUs) –threadnum max of # CPUs * 2 Threads only available in multi user mode Workgroup only supports 1 thread -dumpfile used as input for load
© 2008 Progress Software Corporation35 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Don’t forget SQL SQL Tables and Views These need to be dumped and loaded as well You can use different commands to move the information: sqlschema sqldump sqlload
© 2008 Progress Software Corporation36 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Data Dump Completed. Reorganize the Area/Object Configuration
© 2008 Progress Software Corporation37 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Dump & Modify data definitions Use Data administration tool OR: run prodict/dump_df.p(‘ALL’, ‘.df’, ‘ ’). If using bulk load: run prodict/dump_fd.p(‘ALL’, ‘.fd’).
© 2008 Progress Software Corporation38 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Dump & Modify data definitions Update.df files Optionally delete old table Change table’s area information Delete/Drop tables Load data definitions Data administration tool OR: run prodict/load_df.p(“.df"). ADD TABLE "mytable2" AREA “Old Default Area" DROP Table “mytable2” ADD TABLE "mytable2" AREA “New Data Area"

© 2008 Progress Software Corporation42 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Bulkload proutil -C bulkload -B 1000 –i –Mf 10 Data input from dictionary or custom data dump Mentioned here for completeness only Drawbacks: 2 GB file limit (pre 10.1C) Loads one table at a time (single user) Does not insert index entries –Requires index rebuild as separate step No advantage over other loads Slower than all other loads
© 2008 Progress Software Corporation43 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Dictionary Load Data Administration Tool OR: run prodict/load_d.p(‘table1’, ‘table1.d’). Data input from dictionary or custom data dump 2 GB file limit per load (pre 10.1C) Load data in parallel (to separate tables) Inserts index entries Index tree not perfect Performance close to binary load + index rebuild (when loading multiple tables)
© 2008 Progress Software Corporation44 OPS-10: Moving V8/V9 RDBMS to OpenEdge 10 Binary Load proutil -C load.bd [build] Load to new or truncated area Truncated rather than “emptied” Parallel load to different tables Same or different areas without scatter! When using Type II Areas Optionally load with build indexes Somewhat better performance
