I was SQL Server DBA over 1 year, now i am oracle DBA so i used to use below query against sql server database to get query performance.

SELECT TOP 5
    ObjectName          = OBJECT_SCHEMA_NAME(qt.objectid,dbid) + '.' + OBJECT_NAME(qt.objectid, qt.dbid)
    ,TextData           = qt.text
    ,DiskReads          = qs.total_physical_reads   -- The worst reads, disk reads
    ,MemoryReads        = qs.total_logical_reads    --Logical Reads are memory reads
    ,Executions         = qs.execution_count
    ,TotalCPUTime       = qs.total_worker_time
    ,AverageCPUTime     = qs.total_worker_time/qs.execution_count
    ,DiskWaitAndCPUTime = qs.total_elapsed_time
    ,MemoryWrites       = qs.max_logical_writes
    ,DateCached         = qs.creation_time
    ,DatabaseName       = DB_Name(qt.dbid)
    ,SQLHandle          = CONVERT(VARCHAR(1000), qs.sql_handle, 2)
    ,LastExecutionTime  = qs.last_execution_time
 FROM sys.dm_exec_query_stats AS qs
 CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) AS qt
 ORDER BY DiskReads DESC



Can i get the query in oracle something like above?

If you are licensed for ASH and AWR, then thats the best resource. If not, check out ASH Masters

http://datavirtualizer.com/ash-masters/

and ASHMON and S-ASH.

It's a suite of facilities to give you a holistic view of performance.

See my response below. You need to have the Diagnostics pack to use AWR & ASH. This requires EE.

Standard edition

AWR / ASH is still available for 11g Standard edition.

No. You need to be licensed for the Diagnostics Pack to use ASH / AWR:

http://docs.oracle.com/cd/E11882_01/license.112/e47877/options.htm#DBLIC165

This is extra cost on top of EE and not available for SE / SE1 according to the link you've provided.
