How to view RAM performance

I got the new MBP and installed the new RAM (now have 4 GB). Everything looks great. I would like to see how much RAM the OS is using. I would also like to know how much RAM I can assign to my Scratch disk to use Photoshop. Currently looks like I may have to be careful how many apps I can open at the same time.
But is there a way to see how much RAM is being used at any given moment? System Profiler doesn't seem to do it. Thanks.

Try using Activity Monitor. You might want to check out the MacBook Pro forum to see what others do about scratch disks.
If you have ExpressCard support, I'd add eSATA so you aren't using the boot drive for scratch.
Page outs and vm swap files can tell you if you are using disk, as well as watch the System Memory in Activity Monitor.
Leopard and CS3 should automatically use free memory or cache so you don't actually assign anything, unless you are talking about the percentage preference - I think 70% but it depends on how large or type of files and work you deal with.

How to view database performance in OEM back 8 hour

Hello All,
I have recently installed OEM 11g. Please can I know how to view the performance of the database back 8 hour as I can see the performance for an hour only on the performance page.
Thanks.

Yes, you can.
For instance you can use the ADDM feature (via the Database Homepage --> Adivsor Central --> ADDM --> Run ADDM to analyze past performance

How to view custom performance counter data?

I have created a new MVC application and have added Application Insights to the project. I modified the ApplicationInsights.config file to start collecting the performance counter for Memory\Page Faults/sec. How can I tell if this data is making it to App
Insights? I can't see the data in the portal. When I add a chart in metrics explorer this counter does not exist under the Performance Counters.
Where do I go to view this data? How can I determine if it's working or not? Also the documentation I'm finding on the subject appears to be outdated. Is MMA still used to capture this data? If not, what is used now? Do I need to restart something in order
for this data to start getting collected?
Here is my config:
<?xml version="1.0" encoding="utf-8"?>

Can you please let us know which documentation you're referring to? It does seem to be outdated.
Application Insights collects certain performance counters on its own; unfortunately, the list of performance counters is not configurable as of now. The syntax you're using
<PerformanceCounters>
<PerformanceCounterConfiguration counterSpecifier="\Memory\Page Faults/sec"/>
</PerformanceCounters>
is not supported.
Performance data will be collected automatically (no further configuration needed) as long as the following element is in your ApplicationInsights.config (and it is indeed present in your sample):
<Add Type="Microsoft.ApplicationInsights.Extensibility.PerfCollector.PerformanceCollectorModule,
Microsoft.ApplicationInsights.Extensibility.PerfCollector" />
Performance counters currently collected by Application Insights are:
\Process(<application process>)\% Processor Time
\Memory\Available MBytes
\ASP.NET Applications(<IIS process>)\Requests/Sec
\.NET CLR Exceptions(<application process>)\# of Exceps Thrown / sec
\ASP.NET Applications(<IIS process>)\Request Execution Time
\Process(<application process>)\Private Bytes
\Process(<application process>)\IO Data Bytes/sec
\ASP.NET Applications(<IIS process>)\Requests In Application Queue
\Processor(_Total)\% Processor Time
There are additional factors that may affect performance collection; this blog article contains a section detailing performance collection in Application Insights SDK:
http://blogs.msdn.com/b/visualstudioalm/archive/2014/12/11/updated-application-insights-status-monitor-to-support-12-and-later-application-insights-sdk.aspx
Please check out the section starting with the words "One of the changes made in the .12 version
of the Application
Insights for Web Applications SDK is the collection of the following Windows performance counters."
As you can see from the blog post, you are indeed looking in the right place in the portal (Metric Explorer under Performance Counters), but only the default counters will be collected.
As a workaround, consider taking advantage of one of TelemetryClient.Track* methods to report data to Application Insights.

How to view performance in Oracle10gAS Portal

hi to all
I need your help out there. Do anyone noe how to view all the performance logs in Oracle10gAS Portal? It means in Oracle10gAS how can i see all the no. of hit counter for per page, the most popular website/portlet at the end of the day, portal usage reports and etc. And the reports on the usage of the services and resources? Pls help
Many thanks to you sll out there

Hi Sally,
Sorry I misinterpreted your question. It sounds like what you are looking for is a data warehouse on top of your web logs. Oracle used to sell a product that did this out of the box for Oracle Application Server... but we do not anymore. There are however partners that you may want to look at to find default mappings between a web log format and individual attributes. I know for example SyncSort provides these.
Alternatively, you can evaluate your logs and build something yourself...
Not sure if this addresses your question entirely... There is actually another product that is related to this subject: Oracle Personalization (http://otn.oracle.com/products/personalization/index.html). You may want to take a look at what they provide.
Thanks,
Mark.

How to measure the performance of sql query?

Hi Experts,
How to measure the performance, efficiency and cpu cost of a sql query?
What are all the measures available for an sql query?

How to identify i am writing optimal query?
I am using Oracle 9i... You might want to start with a feature of SQL*Plus: The AUTOTRACE (TRACEONLY) option which executes your statement, fetches all records (if there is something to fetch) and shows you some basic statistics information, which include the number of logical I/Os performed, number of sorts etc.
This gives you an indication of the effectiveness of your statement, so that can check how many logical I/Os (and physical reads) had to be performed.
Note however that there are more things to consider, as you've already mentioned: The CPU bit is not included in these statistics, and the work performed by SQL workareas (e.g. by hash joins) is also credited only very limited (number of sorts), but e.g. it doesn't cover any writes to temporary segments due to sort or hash operations spilling to disk etc.
You can use the following approach to get a deeper understanding of the operations performed by each row source:
alter session set statistics_level=all;
alter session set timed_statistics = true;
select /* findme */ ... <your query here>
SELECT
         SUBSTR(LPAD(' ',DEPTH - 1)||OPERATION||' '||OBJECT_NAME,1,40) OPERATION,
         OBJECT_NAME,
         CARDINALITY,
         LAST_OUTPUT_ROWS,
         LAST_CR_BUFFER_GETS,
         LAST_DISK_READS,
         LAST_DISK_WRITES,
FROM     V$SQL_PLAN_STATISTICS_ALL P,
         (SELECT *
          FROM   (SELECT   *
                  FROM     V$SQL
                  WHERE    SQL_TEXT LIKE '%findme%'
                           AND SQL_TEXT NOT LIKE '%V$SQL%'
                           AND PARSING_USER_ID = SYS_CONTEXT('USERENV','CURRENT_USERID')
                  ORDER BY LAST_LOAD_TIME DESC)
          WHERE ROWNUM < 2) S
WHERE    S.HASH_VALUE = P.HASH_VALUE
         AND S.CHILD_NUMBER = P.CHILD_NUMBER
ORDER BY ID
/Check the V$SQL_PLAN_STATISTICS_ALL view for more statistics available. In 10g there is a convenient function DBMS_XPLAN.DISPLAY_CURSOR which can show this information with a single call, but in 9i you need to do it yourself.
Note that "statistics_level=all" adds a significant overhead to the processing, so use with care and only when required:

FAQ: How do I make Photoshop run faster, or How do I increase performance?

Why doesn't Photoshop run faster?
There are many factors that contribute to the responsiveness of Photoshop. From hardware to software, there a nearly an infinite number of combinations that can boost or hinder Photoshop as it tries to work. Considering factors like how much RAM you have only begins to scratch the surface. Then you have to look at how fast the RAM is and how fast the motherboard will be in supporting it. A computer can only run as fast as its slowest components. Additionally, the hardware resources must be split between all of the running applications. And while you may only be running a web browser at the same time as Photoshop, what about all of the applications running in the background? Security software such as antivirus remains hidden, operating behind the scenes, but it still takes up CPU cycles and RAM. And what about the files you are working with? What are their pixel dimensions? File size on disk? Number of layers, smart objects, styles, and adjustments?
To start, though, you must make sure you meet or exceed the minimum system requirements:
Tech specs
What can I do to make Photoshop run more efficiently?
There are many factors to take into consideration and may steps that can be taken. Here are a list of resources that go into great detail.

Photoshop CS6: The Need for Speed
What about Photoshop taking advantage of the power of my video card?
With each new release of Photoshop, it will take more advantage of you GPU (Graphic Processing Unit), which can process display information much faster than your CPU. You video card also has its own separate RAM (known as VRAM) for storing this information. However, not all video cards are equal, even if they have the same amount of VRAM. There are different display processing technologies that all video cards do not have access to. These include technologies like OpenGL, OpenCL, and Shader Model. And these technologies have different versions that your video card may or may not have.
For more information on Photoshop's use of GPU, please review:
Photoshop CS6 GPU FAQ
FAQ: What features use the GPU and how do I troubleshoot GPU issues?
What other performance boosts has Photoshop gained recently?
While Photoshop tends to gain overall performance upgrades by cleaning up the code to make things run more smoothly with each release, there are a couple new technologies that Photoshop has taken advantage of:

Do you have an idea how to improve the performance ?

Hi All,
Greeting,
I'm doing SEM IP. Regarding the performance, do you have some thought about this ?
So I have planning report for project report . As we know, if we forecast against project, means the date itself is the life of the project itself.
It means it could be more than 10 years (forecast period) and 10 years (actual period). Currently I segregate between actual and forecast into different info cube .
But the performance of the planning report is slow now. Do you have an idea about this how to increase the performance. The performance I mentioned here is when we're going to the report (after putting in the value in the selection screen).
The other question, at this moment, I have a multiprovider than this multi provider consist 2 info cubes ( actual and forecast ). Than my aggregation is sitting on top of that multi-provider .
My question whether that's approach correct or not ? Or do we have to create 1 aggregate (only for forecast), than I have multi-provider consisting forecasting aggregation and actual cube .
than my query will sit on top of that multi-provider ?
Which one is better ??
Thanks a lot all,
really need your help,

Hi,
For the performance tuning, you can consider any of the following three methods,
1. Indices
With an increasing number of data records in the InfoCube, not only the load but also the query performance can be reduced. This is attributed to the increasing demands on the system for maintaining indexes. The indexes that are created in the fact table for each dimension allow you to easily find and select the data.
2. Partitioning
By using partitioning you can split up the whole dataset for an InfoCube into several, smaller, physically independent and redundancy-free units. Thanks to this separation, performance is increased when reporting, or also when deleting data from the InfoCube.
3. Aggregates
Aggregates make it possible to access InfoCube data quickly in Reporting. Aggregates serve, in a similar way to database indexes, to improve performance.
4. Compressing the Infocube
Infocube compression means aggregation of the data ignoring the request idu2019s. After compression, the system need not perform aggregation using the request ID every time you execute a query.
And I feel that as per your scenario, you need to do first compress the data based on user requirements and have only the required data in the infocube.
And for the approach regarding the Aggregation level design, choosing between the two approaches depends on the user requirements. For example,
If you have aggregation level created on top of multiprovider containing actual and forecast cube, in your report (created on top of aggregation level) you can view the key figure values present in both the cubes, which is not possible in the other approach.
So this approach is suited if your requirement is to view the records from both the cubes in your report (Comparing planning and actual values).
The second approach is used if your requirement is only to report on planning forecast cube.
Hopes this solves your issue.
Regards,
Balajee

or
you can use EXPLAIN PLAN

hi,
moving average is a transformation which we use to remove the seasonality from the time series data.
we do it for to forecast based on just trend variability.
if there is already no seasonality in your data you shouldn't see any clear impact.

How to view the change immediately after a java file is modified without restarting server or redeploy?

          Hi All,
          How to view the change immediately after a java file that is used in jsp is modified
          without restarting server or redeploy?
          Moreover, it is better to keep the original session.
          Any suggestion is appreciated.
          Kammau


          Hi,
          In order to have a new version of a java class, the current classloader must be
          deleted and a new one created. This is what redeployment does. I believe that
          this is more of an issue with Sun's implementation of classloaders. You could
          ask BEA support (719.232.7878) and see if they have any plans to periodically
          check jar files to see if java class file timestamps and destroy and re-create
          classloaders on the fly.
          1) You will still have to accept the performance hit of destroying classloaders
          and creating new ones. There isn't any way around that.
          2) I would think you would want to have more explicit control in production and
          integration anyway.
          You can redeploy applications from the command line (script) file not just the
          console.
          Hope this helps,
          pat

Unable to view some performance counters

Hi
I am running Exchange 2013 Mailbox Role on a Windows 2012 Server and in Perfmon there are a few counters which I am unable to view, eg:
MSExchangeTransport Queues\*
I can see the counters, and add some to the right hand pane, but when I click
ok the counters do not appear
I have run the re-register perf counter Powershell script to no avail
I have run lodctr /q but none are disabled
The counters are visible in my lab environment - which should be the same as production (!)
Maybe it is a permissions issue but I cannot see a difference
thanks
