Here top 10 causes are given that are commonly responsible for poor performance of Oracle database:
Poor server optimization A poor server kernel parameters setting and I/O configuration (e.g. direct I/O) settings may leave bad impact on Oracle performance
Bad Design Poor designing or poor normalization of Oracle database are the main crooks of poor performance of Oracle.
Bad disk I/O configuration Wrong use of RAID5, disk channel bottlenecks, and deprived disk striping may also affect its performance.
Poor Optimizer Statistics Previous version of Oracle 10g (automatic statistics), lost/stale CBO statistics and unavailable histograms are general reasons of poor performance
Objects Contention DML performance can be affected by unable to set ASSM, free list or freelist_groups for DML-active tables and indexes.
Under-allocated RAM regions In case, if you are not providing enough RAM for shared_pool_size, pga_aggregate_target and db_cache_size may cause an I/O-bound database.
Non-reentrant SQL All SQL must employ host variables/cursor_sharing=force to make SQL re-usable inside the records cache.
Un-set initialization parameters There are lots of the initialization parameters are created to be set by the DBA (db_file_multiblock_read_count, optimizer_index_caching) and gets unable to set these parameters correctly results in poorly optimized execution plans.
Excessive nested loop joinsGenerally in 64-bit Oracle systems gigabytes available for RAM sorts and hash joins. Unable to set pga_aggregate_target to permit the CBO to select hash joins can slow down the SQL performance.
Human Misfeasance The DBA’s breakdown to observe their database (STATSPACK/AWR), set-up exemption reporting alerts (OEM) and altering their occurrence to match-altering workloads is a major reason of deprived performance.
