EBS 19c DB收集统计信息

在CDB执行
sqlplus / as sysdba
exec dbms_stats.gather_schema_stats(ownname=>'SYS',options=>'GATHER AUTO');
exec dbms_stats.gather_schema_stats(ownname=>'SYSTEM',options=>'GATHER AUTO');
exec dbms_stats.gather_dictionary_stats;
exec dbms_stats.gather_fixed_objects_stats;

在PDB的system用户下运行
sqlplus system/manager@PROD
exec dbms_stats.gather_schema_stats(ownname=>'SYS',options=>'GATHER AUTO');
exec dbms_stats.gather_schema_stats(ownname=>'SYSTEM',options=>'GATHER AUTO');
exec dbms_stats.gather_dictionary_stats;
exec dbms_stats.gather_fixed_objects_stats;

--exec dbms_stats.gather_database_stats(estimate_percent=>100,degree=>48,cascade=>true,granularity=>'ALL',no_invalidate=>false);
set timing on
exec dbms_stats.set_global_prefs('CONCURRENT','TRUE');
exec dbms_stats.gather_database_stats(ESTIMATE_PERCENT=>DBMS_STATS.AUTO_SAMPLE_SIZE, method_opt => 'for all indexed columns', cascade=>true, degree=>48);
exec dbms_stats.set_global_prefs('CONCURRENT','FALSE');

在PDB的apps用户下运行
sqlplus apps/apps@PROD
exec fnd_stats.GATHER_SCHEMA_STATS(schemaname =>'ALL' ,estimate_percent =>'100' ,degree => '48',options =>'GATHER' );

sqlplus apps/apps@PROD
exec fnd_stats.gather_schema_statistics(schemaname=>'ALL',estimate_percent=>dbms_stats.auto_sample_size,degree => '48',options=>'GATHER');
alter system set parallel_max_servers=64 scope=memory sid='*';
alter system set parallel_servers_target=64 scope=memory sid='*';
set timing on;
exec fnd_stats.gather_schema_statistics(schemaname=>'ALL',estimate_percent=>dbms_stats.auto_sample_size,degree => '48',options=>'GATHER AUTO');
