Query for finding Oracle CPU and memory utilization and
I want to gather the report using Oracle views in the same formatas of the report which the top utility gives for Sun-Solaris OS processes.
I want the same type of report for Orcale database processes including all the user processes and the oracle internal processes.
can any body tell me if it is possible.
I am writing the top utility report format below and its contents:
CPU-processor number
TTY-Terminal interfaces used
PID-Process id number
USERNAME-Name of the owner of the process
PRI- Current priority of the process
NI- Nice value
SIZE- total size of process (text+data+stack)
RES-resident size of process
STATE- current state of process
TIME-number of system and CPU seconds the process has consumed
%WCPU-weighted CPU
%CPU-raw CPU
COMMAND- name of the command
thanks in advance

In above query you can also user OFPR.Code, OFPR, Category OFPR.Indicator instead of OFPR.Name.

Write a query for finding STDDEV for OLAP Cube
Can anybody post a sample query which will find the standard deviation of sales for each month in the sample GLOBAL OLAP schema for Oracle 11g.
The OLAP option automatically generates a set of relational views on cubes, dimensions, and hierarchies in Oracle 11g. So how can i write a query for finding the Standard deviation on these views.The easiest way to do this is to do this directly within the AW using a custom calculated measure. In AWM11g you can use the 11g custom measure wrapper to execute the STDDEV function:
olap_dml_expression('function',data type)
For example
olap_dml_expression('STDDEV(cube_name, time_dimension_name)',number)
You can then simply expose this calculated measure as another column in your SQL View and then there is no need to use the SQL equivalent. This means the calculation is performed inside the AW (which is as close to the source data as you can get) ensuring performance of the whole query remains high.
If necessary you can take this a step further, if required, and wrap the STDDEV calculation within an OLAP DML program that would allow you to manipulate the status of time within the calculation. For example, you may want the STDDEV calc to only take into account the last 12 time periods rather than all time periods currently in status.
Hope this helps

Which Event Classes i should use for finding good indexs and statistics for queries in SP.
Dear all,
I am trying to use pro filer to create a trace,so that it can be used as workload in
"Database Engine Tuning Advisor" for optimization of one stored procedure.
Please tel me about the Event classes which i should use in trace.
The stored proc contains three insert queries which insert data into a table variable,
Finally a select query is used on same table variable with one union of the same table variable, to generate a sequence for records based on certain condition of few columns.
There are three cases where i am using the above structure of the SP, so there are three SPS out of three , i will chose one based on their performance.
1) There is only one table with three inserts which gets into a table variable with a final sequence creation block.
2) There are 15 tables with 45 inserts , which gets into a tabel variable with a final
sequence creation block.
3)
There are 3 tables with 9 inserts , which gets into a table variable with a final
sequence creation block.
In all the above case number of record will be around 5 lacks.
Purpose is optimization of queries in SP
like which Event Classes i should use for finding good indexs and statistics for queries in SP.
yours sincerely"Database Engine Tuning Advisor" for optimization of one stored procedure.
Please tel me about the Event classes which i should use in trace.
You can use the "Tuning" template to capture the workload to a trace file that can be used by the DETA. See
http://technet.microsoft.com/en-us/library/ms190957(v=sql.105).aspx
If you are capturing the workload of a production server, I suggest you not do that directly from Profiler as that can impact server performance. Instead, start/stop the Profiler Tuning template against a test server and then script the trace
definition (File-->Export-->Script Trace Definition). You can then customize the script (e.g. file name) and run the script against the prod server to capture the workload to the specified file. Stop and remove the trace after the workload
is captured with sp_trace_setstatus:
DECLARE @TraceID int = <trace id returned by the trace create script>
EXEC sp_trace_setstatus @TraceID, 0; --stop trace
EXEC sp_trace_setstatus @TraceID, 2; --remove trace definition

If you are looking for the packaged procedures and functions source then use user_source data dictionary
select a.object_name,a.procedure_name from user_procedures a,
user_objects b
where a.object_name is not null
and a.procedure_name is not null

How to find out CPU and memory usage for an instance?
Hi DBA Gurus,
How to find out CPU usage and memory usage for an instance?
Any information is appreciated!
Thank you!
Robertyou can calculate cpu usage by adding fallowing three factors which you can get from v$sysstat
1. Parse CPU time : This represents the percentage of CPU time spent parsing SQL statements. Parse time CPU can be a strong indication that an application has not been well tuned. High parse time CPU usually indicates that the application may be spending too much time opening and closing cursors or is not using bind variables.
2. Recursive CPU time : Sometimes, to execute a SQL statement issued by a user, the Oracle Server must issue additional statements. Such statements are called recursive calls or recursive SQL statements. For example, if you insert a row into a table that does not have enough space to hold that row, the Oracle Server makes recursive calls to allocate the space dynamically if dictionary managed tablespaces are being used.
Recursive calls are also generated due to the inavailability of dictionary info in the dictionary cache, firing of database triggers, execution of DDL, execution of SQL within PL/SQL blocks, functions or stored procedures and enforcement of referential integrity constraints
3. Other CPU time : This represents the percentage of time spent looking for buffers, fetching rows or index keys, etc. Generally, \"Other\" CPU should represent the highest percentage of CPU time out of the total CPU time used.
total memory used you can calculate adding
total_agrigate_area+sga
memory usage on os level you can know by fallowing commands
vmstat 5 20 depending upon os -
Recursive query for finding parents and children against two tables
Hi I have two tables where the data is stored hierarchially.
I have found using connect_by, level and other oracle functions doing its job when the data is in one table.
Can I traverse against two tables by using the same oracle functions.
My Table A can go 2 levels deep in my hierarchy and level 3 and so forth has to be done against a different table.
Appreciate your insight..
Thanks in advanceThe number of levels that I can traverse in the first table is dynamic (sometimes 2 levels and sometimes 3 levels and actually no level limit) and then has to dynamically start looking at second table for finding any more levels in the other table.
I was able to implement them seperately and union them.
I was more looking for a comprehensive solution to reduce the number of lines that I have to maintain...
Thanks in advance

Ancient RHEL3 Running Oracle Rac 10G - memory utilization question
As all good things must happen the crappy old systems that never get upgraded come back to bite you.
I have a 4 node RAC cluster running Linux RHEL3. I know .. would love to upgrade it .. but that will take time. Looking for at survival at this point. The system is experiencing High I/O wait. Now, my background is mainly Solaris/AIX and not Linux. So as I work through this problem I am unsure of what I am seeing, since Linux maybe handling memory differently on this OS.
This is what I am seeing:
High I/O wait as shown by TOP
Disk Access Time and Utilization : pretty good .. no device utilized over 30% and <20 millisecond response times from the drives
The real Question is in memory usage:
Host: 32GB
OS: Red Hat Enterprise Linux AS release 3 (Taroon Update 9)
model name : AMD Opteron (tm) Processor 880
Please .. I know its old but try and not laugh.......
The box has 32GB of Memory and I am told by the DBAs that OEM is reporting that SGA is sized correctly and memory ISN"T the problem. But disk access time/utilization isn't really pointing to a particular problem with the OS. The disks are all provided by a SAN.
However, when I look at TOP .. I see that the largest oracle process in RSS size is 8G .. now on all other platforms .. AIX/Solaris when using TOP .. all oracle processes that connect to the SGA will show the full size of SGA. So this is my question. Does Linux do this differently... for the DBAs to tell me SGA is set to 20GB and to only see top showing process with 8GB .. this has me confused. Is the SGA really being set to 20GB????
I can see in a pmap <oracle process> that it appears to be attached but just wanting to rule out a simple Oracle / Linux configuration problem first.
I've included a pmap of both a current Linux process on the troubled system and a pmap of a current oracle solaris host.

I have a 4 node RAC cluster running Linux RHEL3. I know .. would love to upgrade it .. but that will take time. Looking for at survival at this point. The system is experiencing High I/O wait. How/why do you relate this to a memory problem that needs memory utilisation analysed?
It could be that you have a dual fibre via HBA to the SAN and that one port is faulty (e.g. bad cable), thus reducing your I/O to the SAN to a single I/O path.
It could be caused by hotspots on a LUN - and likely because ASM is not being used, this hotspot cannot be automatically load balanced.
Or it could be a number of other factors, such as poorly designed and written app code that performs multiple passes through the same data sets, abuse of PQ slaves, etc.
How does your storage layer look? What do you use for SAN connectivity? What diver s/w is used? How are the LUNs used (cooked/raw)? Is ASM used? What does Oracle session and instance reports ito I/O wait times? Which datafiles are being hit the hardest? Is acrhive logging used and what is the frequency of log switches? Etc. etc.
Memory utilisation does not impact I/O, unless it is swap I/O. And these symptoms are easily seen and easily diagnosed. So I would expect that high memory utilisation may be a symptom, as is I/O wait times, of a potential underlying problem. But it would be premature to blame one (e.g. I/O wait times) on the other (e.g. memory utilisation). -
I'm trying to increate the ulimits for max user processes and open files for the oracle user. I've set the values in limits.conf, /etc/profile and in oracle's environment scripts. Now when I log in as oracle I get the below errors. If I change the ulimits back to the original values errors go away but ulimits aren't changed.

[oracle@servername ~]$Thanks for the update.
I modified the /etc/security/limits.d/90-nproc.conf and added a line for oracle and also modifed the oracle.sh file. The ulimits are setting correctly when I su - oracle but they are still wrong when sshing in as oracle.

Please help in solving this query. I am in urgent need of this.
Thanks in advance.I also have to do in MS Access 2003You also have to ask into an other forum since here it's an Oracle forum, to try to find Oracle solution.
