2 BR*Tools Support for Oracle 11g Agenda BR*Tools support for Oracle 11g general status New Oracle 11g features supported by BR*Tools New options of BRSPACE 7.20 for Lob migration and table compression BRSPACE procedure for Lob migration and table compression SAP 2008, Development Update SAP on Oracle, Page 2

3 BR*Tools Support for Oracle 11g General Status BR*Tools 6.40 No support for Oracle 11g Recommendation: May not be used BR*Tools 7.00 Restricted support for Oracle 11g No support for RMAN backup, restore and verification No support for table reorganization Recommendation: Should not be used BR*Tools 7.10 Full support in relation to previous functions All old DBA procedures/scenarios can still be used (e.g. backups) No explicit support for the new Oracle 11g features Recommendation: Can be used with Oracle 11g as for patch 30 BR*Tools 7.20 Full support for Oracle 11g including new features Include all new developments related to Oracle 11g Recommendation: Should be used with Oracle 11g SAP 2008, Development Update SAP on Oracle, Page 3

4 New Oracle 11g Features supported by BR*Tools 7.20 (1) Online conversion to new SecureFile Lobs Implemented as new action lob2lob within BRSPACE reorganization Lob compression can be activated with the same action Can be done only online (by redefinition), not offline (by move/alter) Support for the new table compression COMPRESS FOR OLTP The feature can be activated during table reorganization by BRSPACE Table and Lob compression can be enabled in the same procedure Support for the new features of Oracle 11g Data Pump Complete compression of the data in export dump files Complete encryption of the data in export dump files Export of individual tables from different schemas Tablespace compression and encryption Allows to set compression and encryption attributes at tablespace level SAP 2008, Development Update SAP on Oracle, Page 4

5 New Oracle 11g Features supported by BR*Tools 7.20 (2) New features in the area of data encryption (TDE) Changing the Wallet password using orapki utility Opening the Oracle Wallet in the database mount status Password protection for closing the Oracle Wallet Improvements in database reset/pit recovery using flashback Increases the reliability of the determination of archivelog files needed Cleaning up new Oracle 11g trace files in diagnostic directories Based on new Oracle 11g parameter diagnostic_dest Aware of new Oracle 11g trace file types, e.g. incident files SAP 2008, Development Update SAP on Oracle, Page 5

6 Advantages of SecureFile Lobs and new Table Compression Advantages of SecureFile Lobs Significant performance improvements Data compression support Data encryption support Advantages of new table compression method Significant space savings SAP 2008, Development Update SAP on Oracle, Page 6

7 LOB conversion and table compression (1) Extended syntax of the action option of BRSPACE tbreorg function reorg - reorganize tables reopart - reorganize table partitions cleanup - cleanup tables after failure stop - stop reorganization suspend - suspend reorganization resume - resume reorganization long2lob - convert LONG fields to (new) LOBs lob2lob - convert old (BasicFile) LOBs to new (SecureFile) LOBs heap2iot - convert heap tables to IOTs iot2heap - convert IOTs to heap tables Default: reorg SAP 2008, Development Update SAP on Oracle, Page 7

8 LOB conversion and table compression (2) Syntax of the new compression option of BRSPACE tbreorg function none - no action ctab - compress tables clob - compress LOBs ctablob - compress tables and LOBs dtab - decompress tables dlob - decompress LOBs dtablob - decompress tables and LOBs ctab_only - compress uncompressed tables only clob_only - compress uncompressed LOBs only ctablob_only - compress uncompressed tables and LOBs only dtab_only - decompress compressed tables only dlob_only - decompress compressed LOBs only dtablob_only - decompress compressed tables and LOBs only Default: none SAP 2008, Development Update SAP on Oracle, Page 8

9 LOB conversion and table compression (3) Syntax of the new lobcompr option of BRSPACE tbreorg function low - low degree of compression medium - medium degree of compression high - high degree of compression Default: medium Preconditions for LOB conversion Locally managed tablespace (LMTS) Automatic segment space management (ASSM) active Can only be done using table redefinition (online reorg) SAP 2008, Development Update SAP on Oracle, Page 9

10 LOB conversion and table compression (4) SAP tables to be excluded from compression Tables with more than 255 columns (Oracle requirement) SAP pool tables (for example, ATAB, UTAB) SAP cluster tables (for example, CDCLS, RFBLG) INDX-type tables (for example, BALDAT, SOC3) The update tables VBHDR, VBDATA, VBMOD, and VBERROR The RFC tables ARFCSSTATE, ARFCSDATA, ARFCRSTATE, TRFCQDATA, TRFCQIN, TRFCQOUT, TRFCQSTATE, QRFCTRACE and QRFCLOG BRSPACE offers a special option and parameter to achieve this Tables with more than 255 columns are automatically excluded Pool and cluster tables, INDX-type tables, ABAP source and ABAP load tables, and update tables are excluded using the special option "-SCT" RFC tables are excluded using the special parameter: _reorg_excl_tab = (ARFCSSTATE, ARFCSDATA, ARFCRSTATE, TRFCQDATA, TRFCQIN, TRFCQOUT, TRFCQSTATE, QRFCTRACE, QRFCLOG) SAP 2008, Development Update SAP on Oracle, Page 10

11 LOB conversion and table compression - Case Study (1) Converting tables with LONGs that are not compressed in SAP system: brspace -u / -f tbreorg -a long2lob -o sap<sid> -s <src_tsp> -t allsel -n <new_tsp> -c ctablob -lc medium -SCT Converting tables with LONGs that are compressed in SAP system: brspace -u / -f tbreorg -a long2lob -o sap<sid> -s <src_tsp> -t allsel -n <new_tsp> Converting tables with old LOBs that are not compressed in SAP system: brspace -u / -f tbreorg -a lob2lob -o sap<sid> -s <src_tsp> -t allsel -n <new_tsp> -c ctablob -lc medium -SCT Converting tables with old LOBs that are compressed in SAP system: brspace -u / -f tbreorg -a lob2lob -o sap<sid> -s <src_tsp> -t allsel -n <new_tsp> SAP 2008, Development Update SAP on Oracle, Page 11

12 LOB conversion and table compression - Case Study (2) Compressing the tables without LONG and LOB fields: brspace -u / -p reorgexcl.tab -f tbreorg -a reorg -o sap<sid> -s <src_tsp> -t allsel -n <new_tsp> -c ctab -SCT Reorganization of the remaining tables from the source tablespace: brspace -u / -f tbreorg -a reorg -o sap<sid> -s <src_tsp> -t allsel -n <new_tsp> ****************************************************************************************** Additional example: changing the compression degree of SecureFile LOBs: brspace -u / -p reorgexcl.tab -f tbreorg -o sap<sid> -t allsel -c clob_only -lc low -SCT SAP 2008, Development Update SAP on Oracle, Page 12
