How to enable Performance Assistant

Hi everyone,
When I click F1 to see the Performance Assistant help it shows nothing but "this web page can not be showed". Then I click Application Help, nothing either. Can anyone tell me how to enable that?
Thanks!

possible problems:
1. you are using an old SAPGUI version and have installed Internet Explorer 7. to fix, use latest SAPGUI 6.40 ot 7.10 with latest patch level.
2. transaction SR13 is mis-configured.

How to Enable Performance Collector in 10g forms ?

Hi,
I'm using 10g forms to collect performance data. I have followed the steps as said by Oracle by following this document "perf_collect.pdf". Though the document talks about Oracle forms 6i, I assume the same will work in Oracle 10g forms.
I have tried the below approach.
===========================================
The code added to the HTML file is as follows:-
<html> <head> ORACLE FORMS.</head>
<body onload="document.pform.submit();" >
<form name="pform" action="http://chn-U100S77.CVNS.corp.covansys.com:8889/forms90/f90servlet/temp.html" method="POST">
<input type="hidden" name="form" value="D:\DevSuiteHome\forms90\server\myapps\MODULE2.fmx">
<input type="hidden" name="userid" value="SCOTT/TIGER@ppaprod">
<input type="hidden" name="obr" value="yes">
<input type="hidden" name="buffer_records" value="YES">
<input type="hidden" name="debug_messages" value="YES">
<input type="hidden" name="array" value="YES">
<PARAM NAME=serverArgs value = "module=module2.fmx userid=scott record=all log=C:\perf_>
</form> </body></html>
=============================
I have change the following parameters in "formsweb" configuration file.
# Sub argument for otherparams
record=all
==============================
Any early reply is highly appreciated.

Hi,
Thanks, it creates XML file right now..
I have created tables etc. i was trying to write the same to an oracle table.

Karandeep,
You can apply the restriction using below approach in OAF.
Step 1 - Modify your VO as below.
SELECT hrorg.organization_id, hrorg.name, hrorg.date_from, hrorg.date_to
FROM hr_all_organization_units hrorg, pa_all_organizations paorg
WHERE paorg.organization_id = hrorg.organization_id
AND paorg.pa_org_use_type = 'EXPENDITURES'
AND NVL (paorg.inactive_date, SYSDATE) >= SYSDATE
AND nvl(paorg.org_id, -1) = :1
AND TRUNC(SYSDATE) BETWEEN hrorg.date_from and NVL(hrorg.date_to,TRUNC(SYSDATE))
ORDER BY UPPER(NAME).
Step 2 - Get the org_id using
String orgId = pageContext.getOrgId();
OAViewObject vo = getTestVO1();
vo.setWhereClauseParam(0,orgId);
vo.executeQuery();Regards,
Gyan

How to enable the "top activities" from the performance in OEM12C?

We installed the 12C OEM. But the "top activities" and other options are not enabled from performance pane. I tried to set the parameter control_management_pack_access = "DIAGNOSTIC+TUNING" . Does not work. As was told that should be due to the databases we are running is 11.2.0.2 standard edition. We have the license for the tuning package. Does anybody knows how to enable the option on standard edition database?
Thanks!

Unfortunately, we are using SE and need to use OEM to monitor on the database performance activities.

How do I perform a "Suite Product Activation" so that Acrobat will start working on my new Retina MacBook Pro?

How do I perform a "Suite Product Activation" so that Acrobat will start working on my new Retina MacBook Pro?
Like others, I have recently upgraded my MacBook Pro to the next generation and migrated all my information from old to new. Everything works seamlessly EXCEPT Acrobat. Photoshop, Indesign, Bridge and Lightroom all seem functional. Acrobat hangs with an error message "Suite Product Activation Needed. Acrobat was installed as part of a suite. To enable Acrobat, please start another element of the suite (such as Photoshop)." Needless to say, starting another element of the suite has NO impact on Acrobat.
This has to be a common problem. Now that Apple has made it really easy to migrate information from old to new machines, it has to come up all the time. What surprises me greatly is that I can't find any coherent answer in these forums.
So how do I get Acrobat running again?

Hi Anubha,
I do not understand what you said below.
I am running Adobe Acrobat Pro Version 9.5.5. I do not remember whether it came with Photoshop or InDesign.
When I open Photoshop, it opens without my having to follow any instructions to activate the software. As a matter of fact, I cannot find my Photoshop serial number anywhere in the Photoshop program itself. I do know it from my profile at Adobe.com. Are you suggesting I deactivate Photoshop on the new computer and then reactivate it using my serial number? Will it reactivate?
When you say
"/Library/Application Support/Adobe" at the root level of the startup disk (not the Library folder inside a user's Home folder)
what do you mean? I do not have a startup disk. I have the original installation disk but that version of Photoshop has been updated a few times.
After staring at your instructions for a while, I realized that you might be talking about the Library/Application Support folders resident on my Macintosh HD, although why you called it a startup disk is unclear to me. IAC, I went into those folders and duly moved the three folders into a new folder I called “Acrob1” and restarted Adobe Acrobat 9 and got the following error message: “AMT Subsystem Failure The licensing subsystem has failed catastrophically. You must reinstall of call customer support.” with a small (6).
By undoing my actions I am back to the staus quo ante.
Now what?
Regards, Robert

There are a number of ways to create a fieldcat.

by populating the internal table fields individually and then
appending the rows. This method can be the most time consuming but can
also allow you more control of the final product.
Beware though, you need to ensure that all fields required are
populated. When using some of functionality available via ALV, such as
total. You may need to provide more information than if you were
simply displaying the result
              I.e. Field type may be required in-order for
                   the 'TOTAL' function to work.

How do I perform a clean install of Lion Server?

There seem to be many sites documenting how to pull out the ESD image and burn a bootable copy of Lion.
What I'd like to know is how do I perform a clean installation of Lion Server?
Is it possible to just install Lion and then open the App Store and install from Purchase without being charged again?

Okay....so Apple does have a guide related to Mass deployment which includes a rough way to do a clean OS X Server clean install. You need to use a NetBoot Lion Server as a boot, but it works.
http://support.apple.com/kb/HT4746
Use these steps to create a NetRestore image of an un-configured Lion Server:
Install OS X Lion, and then Lion Server. This server will be used to create the NetRestore image.
On the server, install the app named "Install Mac OS X Lion" from the Mac App Store (a network connection is required for this process).
Install the Server Admin Tools from http://support.apple.com/downloads/ on the server.
Open the "Install Mac OS X Lion" application, and install to an empty volume. This volume can be a spare partition or external hard drive. Be sure to click the Customize button and to select the Lion Server software.
Once installation is complete, the server will restart from the newly installed volume. Instead of completing the setup assistant, press Command-Q to quit the assistant.
Select the option to shut the server down.
Restart the server and hold the Option key.
When the Startup Manager appears, select the volume which you've already configured Lion Server on.
Open System Image Utility and create a NetRestore image from the newly installed (and still un-configured) volume. If you'd prefer to image the volume after it has already been configured, you can proceed with the setup assistant before booting back to the original installation created in step 1.

How to enable GUI in a non global zone in solaris11?

How to enable graphical logon in a non global zone in solaris11, so the zone can be login by Xmanager? Thanks!

This guide will cover how to setup a basic VNC connection to a Solaris 11 machine. There is also an optional step to allow for persistent VNC connections.
Step 1
Configure GDM to include ‘[security] DisallowTCP=false’ and ‘[xdmcp] Enable=true’.
$ sudo gedit /etc/gdm/custom.conf
# GDM configuration storage
[daemon]
[security]
DisallowTCP=false
[xdmcp]
Enable=true
[greeter]
[chooser]
[debug]
Step 2
Configure X-Server to accept remote connections.
# svccfg -s application/x11/x11-server
svc:/application/x11/x11-server> setprop options/tcp_listen = boolean: true
svc:/application/x11/x11-server> end
Step 3
Configure the VNC service (you could change the ‘-geometry 1280×720′ to whatever resolution you would like).
# svccfg -s xvnc-inetd
svc:/application/x11/xvnc-inetd> setprop inetd_start/exec = astring: "/usr/bin/Xvnc -desktop sol11:0 -geometry 1024x768 -inetd -query localhost -once securitytypes=none"
svc:/application/x11/xvnc-inetd> setprop inetd/wait = boolean: true
svc:/application/x11/xvnc-inetd> end
** The line highlighted red is optional – only do this if you want your VNC connection to persist (as well as any potential security issues)
or
# svccfg -s xvnc-inetd
svc:/application/x11/xvnc-inetd> editprop
search for # setprop inetd_start/exec = astring: "/usr/bin/Xvnc
copy the line, uncomment the copy, makethe changes above, write the file out.
svcadm refresh xvnc-inetd
Step 4
Disable and the re-enable the GDM and VNC-inetd services for the changes to take effect.
$ su root
Password:
# svcadm disable gdm xvnc-inetd; svcadm enable gdm xvnc-inetd
If still in maintenance, reboot (I had to, don't know why).
Step 5
Point your favourite VNC client at your Solaris server and test if it accepts your VNC connection – you should be presented with a Username/Password login screen.
If you performed the optional step to make your connections persist – close your favourite VNC client and then reconnect – if you remained logged in you have a persistent connections.
Greg on said:
After a fresh text install of Solaris-11 (11/11) both xvnc-inetd and gdm are not present. After installing them (# pkg install xvnc-inetd gdm) I can’t get gdm to start:

Any thoughts?

You are missing some X packages. Do the following:
pkg install slim_install           # installs 400+ packages
svcadm enable gdm && exit      # gdm now works
pkg uninstall slim_install           # uninstalls the installer package only

How to enable hardware virtualisation support?

Today I upgraded to mac os x lion and when I open parallels desktop it asks me to enable hardware virtualisation support on my MacBook pro so that I can run windows xp as a virtual machine. I have searched the net and cannot find a way to access the bios to enable this feature, please could I have some support and advise on how to enable the VT. I did have any problems whilst I was on os x snow leopard and parallels used to work fine.
Thanks in advance.

Boot camp is the way to go then you will be able to turn it on. Run boot camp install windows xp and you be able to get into the bios
Here's some other help full info as well
VMware Fusion 3.1.3 was designed for OS X 10.6 (Snow Leopard) but is compatible with Mac OS X 10.7 (Lion), with the reservations listed below. If you are running an older versions of VMware Fusion, upgrade to VMware Fusion 3.1.3 before upgrading to Lion. Fusion 2.x is incompatible with Lion. For the best experience, reinstall Fusion after upgrading to Lion. When running Fusion on Lion, these limitations are known to exist:
The Migration Assistant, included with VMware Fusion, is not compatible with Mac OS X Lion. This is due to a change in file sharing components.
VMware recommends that a Snow Leopard-based Mac be used to migrate an existing PC. The resulting virtual machine can then be used in Fusion running on Lion.
Boot Camp partitions are not accessible through Fusion after upgrading to Lion.
To work around this issue, delete the Boot Camp virtual machine from the library and recreate it. For more information, see A Boot Camp virtual machine fails to power on with a disk error (1003483).
Minor visual issues have been reported when using Mission Control with Unity mode.
Mac OS X 10.7 (Lion) Client and Server cannot be run as guests, at this time.
VMware can provide best effort support if you choose to upgrade to Lion, but we cannot guarantee a resolution for all issues.

How to do performance tuning in EXadata X4 environment?

Hi, I am pretty new to exadata X4 and we had a database (oltp /load mixed) created and data loaded.
Now the application is testing against this database on exadata.
However they claimed the test results were slower than current produciton environment. and they send out the explain plan, etc.
I would like advices from pros here what are specific exadata tuning technics I can perform to find out why this is happening.
Thanks a bunch.
db version is 11.2.0.4

Hi 9233598 -
Database tuning on Exadata is still much the same as on any Oracle database - you should just make sure you are incorporating the Exadata specific features and best practice as applicable. Reference MOS note: Oracle Exadata Best Practices (Doc ID 757552.1) to help configuring Exadata according to the Oracle documented best practices.
When comparing test results with you current production system drill down into specific test cases running specific SQL that is identified as running slower on the Exadata than the non-Exadata environment. You need to determine what is it specifically that is running slower on the Exadata environment and why. This may also turn into a review of the Exadata and non-Exadata architecture. How is application connected to the database in the non-Exadata vs Exadata environment - what's the differences, if any, in the network architecture in between and the application layer?
You mention they sent the explain plans. Looking at the actual execution plans, not just the explain plans, is a good place to start... to identify what the difference is in the database execution between the environments. Make sure you have the execution plans of both environments to compare. I recommend using the Real Time SQL Monitor tool - access it through EM GC/CC from the performance page or using the dbms_sql_tune package. Execute the comparison SQL and use the RSM reports on both environments to help verify you have accurate statistics, where the bottlenecks are and help to understand why you are getting the performance you are and what can be done to improve it. Depending on the SQL being performed and what type of workload any specific statement is doing (OLTP vs Batch/DW) you may need to look into tuning to encourage Exadata smart scans and using parallelism to help.
The SGA and PGA need to be sized appropriately... depending on your environment and workload, and how these were sized previously, your SGA may be sized too big. Often the SGA sizes do not usually need to be as big on Exadata - this is especially true on DW type workloads. DW workload should rarely need an SGA sized over 16GB. Alternatively, PGA sizes may need to be increased. But this all depends on evaluating your environment. Use the AWR to understand what's going on... however, be aware that the memory advisors in AWR - specifically for SGA and buffer cache size - are not specific to Exadata and can be misleading as to the recommended size. Too large of SGA will discourage direct path reads and thus, smart scans - and depending on the statement and the data being returned it may be better to smart scan than a mix of data being returned from the buffer_cache and disk.
You also likely need to evaluate your indexes and indexing strategy on Exadata. You still need indexes on Exadata - but many indexes may no longer be needed and may need to be removed. For the most part you only need PK/FK indexes and true "OLTP" based indexes on Exadata. Others may be slowing you down, because they avoid taking advantage of the Exadata storage offloading features.
You also may want evaluate and determine whether to enable other features that can help performance including configuring huge pages at the OS and DB levels (see MOS notes: 401749.1, 361323.1 and 1392497.1) and write-back caching (see MOS note: 1500257.1).
I would also recommend installing the Exadata plugins into your EM CC/GC environment. These can help drill into the Exadata storage cells and see how things are performing at that layer. You can also look up and understand the cellcli interface to do this from command line - but the EM interface does make things easier and more visible. Are you consolidating databases on Exadata? If so, you should look into enabling IORM. You also probably want to at least enable and set an IORM objective - matching your workload - even with just one database on the Exadata.
I don't know your current production environment infrastructure, but I will say that if things are configured correctly OLTP transactions on Exadata should usually be faster or at least comparable - though there are systems that can match and exceed Exadata performance for OLTP operations just by "out powering" it from a hardware perspective. For DW operations Exadata should outperform any "relatively" hardware comparable non-Exadata system. The Exadata storage offloading features should allow you to run these type of workloads faster - usually significantly so.
Hope this helps.

How to Achieve Performance Tuning In BPM Studio

Please Tell me how to achieve performance Tuning in BPm Project . let me know do have any documentation for this .
Thanks in Advance .

*5. Group Automatic Activities in a Single Transactional Boundary*
When you have several automatic activities in a sequence, recognize this as a potential performance improvement opportunity. The default behavior of Oracle BPM is during each Automatic activity's execution:
1. Initiate the transaction
2. Read the work item instance's variable information from the Engine's database
3. Execute the logic in the Automatic activity
4. If no system exception occurs, commit the transaction and write the instance variable information back to the Engine's database
Many times you'll instead want to speed execution when there are several Automatic activities in a sequence. If three Automatic activities are in a sequence, then the four items listed above will occur three times. By grouping these into a single transactional boundary, instead of 12 steps you would have:
1. Initiate the transaction
2. Read the work item instance's variable information from the Engine's database
3. Execute the logic in the first Automatic activity
4. Execute the logic in the second Automatic activity
5. Execute the logic in the third Automatic activity
6. If no system exception occurs, commit the transaction and write the instance variable information back to the Engine's database
This grouping of Automatic activities into a single transactional boundary can be done in one of these three ways:
1. Create a Group around the sequence of Automatic activities (lasso the three activities) -> right mouse click inside the dotted line -> click "Create a Group with Selection" -> click "Runtime" in the upper left corner -> click the checkbox "Is Atomic".
2. Instead of placing the Automatic actiivities in the process, add them in a Procedure and then call the Procedure from a new Automatic activity in the process.
3. In Oracle BPM 10g you can enable "Greedy" execution for the process by right mouse clicking the process's name in the Project Navigator tab -> click "Properties" -> click the "Advanced" tab -> click the "Enable Greedy Execution" radio button.
