Comparative performance data?

Is anyone aware of benchmark performance comparisons for Oracle on Linux vs. Oracle on NT? Any recommendations, performance-based or otherwise, for why to prefer one OS over the other as an Oracle server?

Topics to consifder:
Almost all arguments are Windows NT versus Unix in general.
1. Your sleep at night:
Unix Systems seem to be much more stable. That is what I want as a system/database admin.
2. Filesystems
Unix Filesystems can be changed without any serious problems. You can mount a filesystem to another drive or storage system. That means while your amount of data is growing you can do fundamental stoarage reorganisations. No annoying drive letters, which are subjet of change after repationing.
3. Full telnet support, so you can do almost erverything (unix) via modem line if you want to.
4. Full X support on remote systems. You can get your gnome/kde/cde Desktop at home via network connection.
5. You can follow OFA. That means backup with "tar -cvf /dev/rmnt /u[0-9[0-9]/oradata/<instance>/*" and you are done.

Comparing SQL Data Results with CSV file contents

I have the following scenario that I need to resolve and I'm unsure of how to approach it. Let me explain what I am needing and what I have currently done.
I've created an application that automatically marks assessments that delegates complete by comparing SQL Data to CSV file data. I'm using C# to build the objects required that will load the data from SQL into a dataset which is then compared to the
associated CSV file that contains the required results to mark against.
Currently everything is working as expected but I've noticed that if there is a difference in the number of rows returned into the SQL-based dataset, then my application doesn't mark the items at all.
Here is an example:
ScenarioCSV contains 4 rows with 8 columns of information, however, let's say that the delegate was only able to insert 2 rows of data into the dataset. When this happens it marks everything wrong because row 1 in both CSV and dataset files were correct,
however, row 2 in the dataset holds the results found in row 4 in the CSV file and because of this it is comparing it against row 2 in the CSV file.
How can I check whether a row, regardless of its order, can be marked as it does exist but not in the same order, so I don't want the delegate to lose marks just because the row data in the dataset is not perfectly in the same order of the row data
in the CSV file???
I'm at a loss and any assistance will be of huge help to me. I have implemented a ORDER BY clause in the dataset and ensured that the same order is set in the CSV file. This has helped me for scenarios where there are the right number of rows in the dataset,
but as soon as there is 1 row that is missing in the dataset, then the marking just doesn't allow for any marks for both rows even if the data is correct.
I hope I've made sense!! If not, let me know and I will provide a better description and perhaps examples of the dataset data and the csv data that is being compared.
Thanks in advance....

I would read the CSV into a datatable using oledb. Below is code I wrote a few weeks ago to do this.
Then you can compare two datatables by a common primary key (like ID number)
Below is the webpage to compare two datatables
http://stackoverflow.com/questions/10984453/compare-two-datatables-for-differences-in-c
You can find lots of examples by perform following google search
"c# linq compare two dattatable"
//Creates a CSVReader Class
public class CSVReader
public DataSet ReadCSVFile(string fullPath, bool headerRow)
string path = fullPath.Substring(0, fullPath.LastIndexOf("\\") + 1);
string filename = fullPath.Substring(fullPath.LastIndexOf("\\") + 1);
DataSet ds = new DataSet();
try
if (File.Exists(fullPath))
string ConStr = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0}" + ";Extended Properties=\"Text;HDR={1};FMT=Delimited\\\"", path, headerRow ? "Yes" : "No");
string SQL = string.Format("SELECT * FROM {0}", filename);
OleDbDataAdapter adapter = new OleDbDataAdapter(SQL, ConStr);
adapter.Fill(ds, "TextFile");
ds.Tables[0].TableName = "Table1";
foreach (DataColumn col in ds.Tables["Table1"].Columns)
col.ColumnName = col.ColumnName.Replace(" ", "_");
catch (Exception ex)
MessageBox.Show(ex.Message);
return ds;

Comparing AWR data with baselines.

Hello,
I am studying AWR, which will be used in our project for performance analysis.
My requirement is to create a baseline of load between 2 snapshots during normal system load. We perform load/stress testing before final deployment. We are planning to take snapshots before and after load/stress tests. I want to compare the performance of instance during load/stress test with that of baseline performance.
Oracle provides package DBMS_WORKLOAD_REPOSITORY for different functions of AWR. It provides function CREATE_BASELINE function for creating baseline. But in report generation function AWR_REPORT_HTML or AWR_REPORT_TXT no parameter is specified for comparing it with the baseline.
Is it possible to compare AWR data with baseline, during report generation? Or currently Oracle supports only baseline creation and dropping that baseline. It can not be used for performance comparison.
Thanks,
Shailesh

How to compare delivery date in schedule lines and PGI in outbound delivery

Hi,
I want to create a report to monitor and compare different dates in sales and delivery process.
One of my key figure is the comparison between date confirmed to the customer, that I can find in the schedule line of the sales order, and the actual goods issue date from the outbound delivery.
But I can't succeed in making the link between delivery and schedule lines, means between LIKP and VBEP.
Would you have any idea?
Thank you.

It seems there's no exact (table) connection / link between delivery item and schedule line item.
Those who were searching for this thing (link / connection between delivery item and schedule line) were recommended to use FM "RV_SCHEDULE_CHECK_DELIVERIES".
This FM calculates the delivered quantity for each schedule line, so it makes link between the delivery item and schedule lines - however if you check the code it's quite sophisticated...
(if you put a breakpoint in the FM and display a SO in VA03, you can check how the parameters have to be populated with data).

Not able to extract performance data from .ETL file using xperf commands. getting error "Events were lost in this trace. Data may be unreliable ..."

Not able to extract performance data from .ETL file using xperf commands.
Xperf Commands:
xperf –i C:\TempFolder\Test.etl -o C:\TempFolder\BootData.csv –a process
Getting following error after executing above command:
"33288636 Events were lost
in this trace.
Data may be unreliable
This is usually caused
by insufficient disk bandwidth for ETW lo
gging.
Please try increasing the minimum
and maximum number of buffers
and/or
the buffer size.
Doubling these values would be a good first at
tempt.
Please note, though, that
this action increases the amount of me
mory
reserved
for ETW buffers, increasing memory pressure on your sce
nario.
See "xperf -help start"
for the associated command line options."
I changed page size file but its does not work for me.
Any one have idea, how to solve this problem and extract ETL file data.

I want to mention one point here. I have total 4 machines out of these 3 machines above
commands working properly. Only one machine has this problem.<o:p></o:p>
Hi,
I consider that you can try to use xperf to collect the trace etl file and see if it can be extracted on this computer:

Report/Widget for combined performance data

Hello.
I have created a dashboard view in SCOM 2012 R2 for power consumption of a number of servers. These servers are all part of a group. The power consists of a couple of different performance monitors (VMWare-sensor for VMs and Power Meter from the Power
Consumption MP)
The dashboard view works well, however I am after a total figure for each server in the group. Ideally this figure would be on the dashboard view as well.
E.g. if I have 3 servers with the below power draw
Server 1 – 150 Watts
Server 2 – 200 Watts
Server 3 – 300 Watts
I would like a box stating total power 650 Watts
If this is not available in a dashboard view, a report would be okay
Thanks

Hi,
As far as I know, there is no direct way, you may create a sql query and sum the value for each server.
You may refer to the helpful article below:

How to compare 2 dates in a JPA QL query

hello all,
how can i compare 2 dates in JPA QL ,?
my idea was to convert the dates to String, and i used 'to_char',
but i think it doesn't work in JPA QL;
this is my query(it works in oracle but not in java) :
Query q=em.createQuery("select sum(o.montant) from Operation o join o.codTransac t join o.codCaisse c where (t.sens='D')and (to_char(c.dateCaisse,'MM/DD/YYYY')=to_char(o.dateOp,'MM/DD/YYYY'))");
can some one help me?
thanks

I don´t know if it´s the same case, but I had a similar problem and I`m posting here the way I solved it (maybe it isn´t the best solution but worked to me).
I have to compare a date come from a web form (format dd/mm/yyyy) with a Timestamp data from DB (dd/mm/yy hh24:mi:ss).
Solution:
//String dateTo from web form
//Substring here were used to get only dd/mm/yy from DB and ignore the hours
ql.append(" SELECT o FROM Table o WHERE SUBSTRING(o.dateTime,1,8) = :end ");
q = getEntityManager().createQuery(ql.toString());
q.setParameter("end",convertStringToDateSimple(dateTo));
//function used to parse the String date and return in an appropriate format expected in the above query
public static String convertStringToDateSimple (final String source)
     final SimpleDateFormat format = new SimpleDateFormat("dd/MM/yy");
          String parsed = null;
               try
                    parsed = format.format(format.parse(source));
               catch (ParseException e)
                    throw new RuntimeException(e);
          return parsed;

How to compare 2 dates in SQL Server 2000 DB using Java?

How do you compare 2 dates in SQL Server 2000 DB using Java?
Let's say we have two fields: Date Reported and Target Finish Date.
Date Reported is 09-10-2004 09:55:55: PM
Target Finish Date is 09-12-2004 11:59:59: PM
What i want to happen is i want to convert both dates to days and get the difference of the two.
can SQL Server 2000 DB do this?

it doesnt wrk.
ok here's what i did:
iv tested a simple code for this case.
I created a table name tblDate which has 3 columns namely date_ID, date_From (datatype datetime), date_To (datatype datetime).
I inserted 1 row: date_ID has the value 1, date_From has the value 10/22/2004, and date_To has the value 10/24/2004.
i run the java code below:
int days = 0;
          String query = "SELECT date_From, date_To cast(date_From-date_To AS int) AS Diff FROM tblZoo WHERE date_ID = '1'";
          try
               DBConnect db = new DBConnect();
               db.openCon();
               ResultSet rs = db.execute(query);
               while(rs.next())
                    days = rs.getInt("Diff");
               db.closeCon();
          catch (Exception ex)
               System.out.println("Error on Execution: " + ex);
          return days;___________
an error occurred: Error on Execution: java.lang.nullpointerexception

Compare two dates in a report

Hi,
I would like to compare two dates on a report.
I would like to compare the opportunity created date and the opportunity modified date. I can't use this formula CASE WHEN Opportunity."Last Modified" = Opportunity."Created Date" then 1 else 0
I think I have to use TIMESTAMPDIFF but I don't know which interval I have to put to analyze the entire date in this format 31/12/1999 16:49:08
Thanks a lot for your help
Regards,

Hi !
It depends on the interval you need to compare these dates. If you want to know the number of days between these dates, you'll have to use SQL_TSI_DAY as interval. If it's minutes, you'll need SQL_TSI_MINUTE...
Here are the possible intervals :
*SQL_TSI_SECOND, SQL_TSI_MINUTE, SQL_TSI_HOUR, SQL_TSI_DAY, SQL_TSI_WEEK, SQL_TSI_MONTH, SQL_TSI_QUARTER, or
SQL_TSI_YEAR*
Hope this will help, feel free to ask more !

Compare two dates in different format.

Hi
I want to compare two dates....one of which is in the timeStamp format ("yyyy-MM-dd HH:mm:ss")
and the other is in java.util.Date i.e Tue Oct 11 10:22:47 GMT+05:30 2005
Do I have to tokenise and then compare them.Is there any better approach?
I want to find out which is greater/smaller one.
Pls help.
Regards,
Sandip.

I would convert both to Date and compare them. To convert String to Date check java.text.SimpleDateFormat and its parse(...) method.
