10g Features - Manageability

• Automatic Workload Repository (AWR)• “Data Warehouse” of the Database• Replacement for StatsPack• Takes periodic snapshots

• Automatic Database Diagnostic Monitor (ADDM)• Performance Diagnostic engine in the database• Automatically diagnoses performance problems • Provides Root Cause Analysis with recommended solutions• Identifies non-problems areas• Integrates all components

10g Features - Manageability

• Automatic SGA tuning• Automatically sizes the individual SGA caches:

• Buffer cache• Shared pool• Java pool

• Uses Advisory information to dynamically size the caches.• Just set sga_target=<SGA size>

• sga_target=10G

10g Features – Optimizer Enhancements

• RBO Rest in Peace!!• CPU Costing• Cost Based Transformations

• Sub-query un-nesting• View merging• Pushing of join predicates

• Cartesian Joins no longer considered when a connection exists.• Hash based Aggregation

• HASH GROUP BY row source instead of SORT GROUP BY

• Runtime execution plans available via v$sql_plan.• Bind variable values are captured via v$sql_bind_capture

10g Features – Optimizer Enhancements

• Plan table includes the following new columns:• CPU_COST : estimated CPU cost • IO_COST: estimated I/O cost• TEMP_SPACE : estimated temporary space, in bytes, used by the

operation; Network usage for query servers running on different nodes will be estimated

• Time: an estimate of how long each row source will take.• Query Block Name (qblock_name) – can be used in conjunction

with query block hint.

• dbms_xplan.display_cursor() can be used to show runtime plan of a cursor.

10g Features – Optimizer Enhancements

• New Format includes CPU cost, and time.------------------------------------------------------------------------------------------------------------------| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |------------------------------------------------------------------------------------------------------------------| 0 | SELECT STATEMENT | | 1 | 74 | 7 (0)| 00:00:01 || 1 | SORT AGGREGATE | | 1 | 74 | | ||* 2 | TABLE ACCESS BY INDEX ROWID | MTL_ITEM_CATEGORIES | 1 | 9 | 2 (0)| 00:00:01 || 3 | NESTED LOOPS | | 1 | 74 | 7 (0)| 00:00:01 || 4 | NESTED LOOPS | | 1 | 65 | 5 (0)| 00:00:01 || 5 | MERGE JOIN CARTESIAN | | 1 | 42 | 4 (0)| 00:00:01 ||* 6 | TABLE ACCESS FULL | FINANCIALS_SYSTEM_PARAMS_ALL | 1 | 4 | 4 (0)| 00:00:01 || 7 | BUFFER SORT | | 1 | 38 | 0 (0)| 00:00:01 ||* 8 | TABLE ACCESS BY INDEX ROWID| PO_APPROVED_SUPPLIER_LIST | 1 | 38 | 0 (0)| 00:00:01 ||* 9 | INDEX RANGE SCAN | PO_APPROVED_SUPPLIER_LIST_N1 | 1 | | 0 (0)| 00:00:01 ||* 10 | TABLE ACCESS BY INDEX ROWID | PO_ASL_STATUS_RULES | 1 | 23 | 1 (0)| 00:00:01 ||* 11 | INDEX RANGE SCAN | PO_ASL_STATUS_RULES_U1 | 4 | | 0 (0)| 00:00:01 ||* 12 | INDEX RANGE SCAN | MTL_ITEM_CATEGORIES_N3 | 3695 | | 2 (0)| 00:00:01 |------------------------------------------------------------------------------------------------------------------

10g Features – Optimizer Enhancements

• Workload Statistics• Workload statistics allows the optimizer to learn the patterns

of load and the duration of peak loads.• Adaptive execution plans.

• The CBO might choose different execution plans based on the workload statistics.

10g Features – Optimizer Enhancements

• SQL Tune• Optimizer spends more time by widening the search space

and sampling in order to generate a more efficient plan.• SQL Tune profiles are saved.• Profiles can be created via the SQL Tuning Advisor via DB

Console.• Extremely useful for complex Applications SQL for which the

default plan was not optimal.• Immediate performance relief.

10g Features – PL/SQL Enhancements

• Every line of PL/SQL code runs 2X faster.• Global Optimizer.• Improved Native Compilation.• Reduced collections memory footprint (15%).

10g Features – PL/SQL Enhancements

• Global Optimizer• Eliminates temporary operands generated by the PL/SQL

compiler. Such elimination causes less storage to be used and less time taken initializing temporary values.

• Computes certain operations during compilation rather that during execution.

• Reuses expression values. • Converts single row fetches to bulk fetches.

10g Features – PL/SQL Enhancements

• Native Compilation• Natively compiled PL/SQL code executes even faster than

in earlier releases.• The natively compiled units are stored in the database as

BLOB data.• Improves RAC Deployment

• You can switch between native and interpreted compilation for stored PL/SQL code for debugging purposes.

10g Features

• Rename a Tablespace.• Online segment shrink.• Automatic undo retention tuning.• Semi-static VPD policies.

• Policy function is only invoked when context is reset.

• Partitioning• List Partitioning enhancements• Global hash partitioned indexes.

10g Features

• Library Cache Optimizations• New efficient mutex is used to pin/unpin cursors• Reduces library cache pin latch contention considerably• Performance Improvement ranges from 10%-90% depending

on the amount of time spent in library cache latch contention (due to pins).• Init.ora parameter _kks_use_mutex_pin=TRUE enables this

optimization• Enabled by default in 10.2.0.2
