Setting Portal Page Entitlements Painfully Slow

Does anyone have any tips on speeding up the Portal Admin Tool entitlement setup processing? We're trying to setup a new portal with about 180 different entitlements and assigning entitlements to the portal objects (pages and portlets) is taking forever. The response time for clicking the Entitlement tab for a single portal page is about 20 seconds. Add to that the fact that it seems to re-retrieve the entitlement information after each action (select a page, add the entitlement, set the accesses for the entitlement) and you're talking about a significant amount of time to setup each entitlement. Now multiply that over 180 entitlements that need to be assigned.
The bottom line question is, are there tunings we can perform?
Some additional information:
- We are on WebLogic 8.1 SP4
- Our database is Oracle 9i
Any help would be greatly appreciated.

Trying do it in dev - bear the pain and then use the propogation tool to move them to other environments. At least you just have to do it once. Pre-Sp4 -- the prop tool hardly worked.. so u would feel the pain in each environment.
BEA is making progress :)
BTW - 20 secs seems a long time. It takes me just 4-5 seconds. Are u sure that you bea server is tuned properly?

Set Portal Page URL in Web Dynpro IFrame

Hi All,
I've a Web Dynpro application that runs in the portal.
The application creates iframes dynamically.
I want to set in the iframes portal pages.
In order to get the page's url, I go to content admin, navigate to the page and then press the 'preview' button then I copy the url from the browser's address bar.
I copy the url from the '/irj....' to the src property of the IFrame UI element.
So the source property looks something like this:
/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.mycomp.Omri!2fcom.mycomp.TestPage
When I run the project I get:
<i>Portal Runtime Error
An exception occurred while processing a request for :
iView : N/A
Component Name : N/A
Access denied (Object: portal_content/.../...).
Exception id: 06:01_17/10/06_0015_4401150
See the details for the exception ID in the log file</i>
The page's permissions are set to everyone so I don't know why do I get this error.
So, how do I set portal page url in Web Dynpro IFrame?
p.s
I tried to use NavigatinTarget in the URL and it works. The problem is that the TLN is included. I want to display only the page.
Thanks,
Omri

Hi Valery,
I have only one domain...
I searched SDN and I found this post:
/message/1259616#1259616 [original link is broken]
Daniel Wroblewski from SAP says:
<i>This, naturally, sounds like a permission issue. Two steps:
You must give the Everyone group end-user permission to the iView. This will eliminate the error and cause a login screen to display.
If you want to eliminate the login screen, you must set the iView property Authentication Scheme to anonymous.</i>
I will try it tomorrow in the Office.

Airport reception fine but painfully slow

Hi,
I've had my macbook pro for about 1 year now and just in the last week the WiFi at home is almost unusable (haven't tried it elsewhere yet). Reception is fine, all bars showing, but loading web pages is painfully slow, with the blue progress bar stalling, loading normally for a bit, then stalling again, and so-on until eventually I get a timeout or it has seemingly stalled indefinitely. Here's what I've done so far to isolate the problem:
1. Windows PC has perfect internet access through the same wireless router.
2. Connected macbook directly to DSL modem via ethernet cable, and internet access was perfect.
3. Deleted the airport connection settings in System Preferences, then re-established the settings - problem didn't go away.
So I think this rules out a broken router and modem and also rules out a problem with the macbook talking to my ISP (and hopefully rules out any ID10T errors on my part). So I suspect the problem lies with the macbook.
I don't know what's changed recently to suddenly cause this problem, some updates maybe?
Anyone have any ideas on how I can fix this?
Thanks

"...(haven't tried it elsewhere yet)..."
Do that. Then post back.

Hi,
Welcome to SDN
By defining the Sort Sequence of Navigation Nodes, you can do this, check the links:

Portal page colums width setting

Hi,
I defined portal page and i set layout as "3 colums narrow-wide-narrow".
Is it possible to set widths of colums as pixel or as percent of screen width?
Thanks.

Hi,
You could create a Custom Layout with Properties that can be set on the fly via the Layout Properties in the PCD:
The JSP
The portalapp.xml

Set isolatedHtmlContainer height when displaying portal page

Hi,
I have a portal application which displays portal pages from the pcd in isolatedHtmlContainer.
The page's content is dynamic so the height is not fixed and therefore in the page's properties the height's value set to 'Automatic'
However, when working with isolatedHtmlContainer the height could be set in pixels or percentage only (I cannot set it to 'Automatic').
p.s
If the height was fixed I could get it by the profile of IPortalComponentContext, but if I will do that I'll get a string like 'Automatic' which doesn't help me...)
Thanks,
Omri

Hi Martin,
I read the blog but the javascript doesn't affect my IsolatedHtmlContainer.
Let me rephrase my question:
In the portal innerpage I display X IsolatedHtmlContainers (my application decides how many pages to display). Each container has dynamic content (a portal page from the pcd), therefore, I have a problem setting the height of the IsolatedHtmlContainers (too low - scrolling bar, too high - blank space).
The properties of the portal pages from the pcd are set as follows:
isolation method - URL
height method: Automatic
If I display the pages without the IsolatedHtmlContainers, the 'Automatic' feature works and the page's size is OK.
So my question is:
Is there a way for the IsolatedHtmlContainer adjust its size according to its content?
Thanks,
Omri

Set two views in one portal page

Hello all,
I need to set two views in one portal page, or tow deferent views have to be setted in one view, unfortunately i didn't find anythings in SAP forums about this subject
please help me to reso

Are you saying you have two separate WD Applications (both FPM) which you want to run as two iViews in the same Portal Page? If so, this is a very basic NetWeaver Portal capability - to add more than one iView to a Page. However this isn't the correct forum to discuss this, as that discussion would belong in the NetWeaver Portal Forum.

Pages 4.1 is so painfully slow

Pages '09 4.1 is so painfully slow - it takes over my entire computer and everything just drags.... I need this app for my business but I don't know what to do. I am mostly touching up photographs using the Alpha Mask. I absolutely cannot have iPhoto and Pages open at the same time. I end up having to shut everything down in order for it to work. I am in version Mac OSX 10.7.2

2 Gb is not much, 4gb is much more comfortable and best to max it out for your model, RAM is cheap.
Lion is more demanding and slower than Snow Leopard.
It sounds like you have an iMac 20" early 2008. Installation is very easy:
http://support.apple.com/kb/HT1423#2
Apple reports that you can add up to 4Gb (2x2) of RAM but you can go to 6Gb.
You need 2GB + 4GB Kit DDR2 SODIMM PC2-6400 800Mhz Unbuffered Non ECC
Make sure you tell the supplier it is for the Mac, which is quite picky.
Double check I have identified your Mac correctly:
Menu > Apple > About this Mac > More Info… > Hardware > Model Identifier: iMac 8,1

Execution order of objects into a Portal page

Hi, to all.
I have a portal page (Oracle Portal 10.1.4) with many Areas (Items and Portlets). Every area contains one or more components (java portlet, plsql portlet,
dynamic page, plsql item, html portlet and so on). Let say 5 areas and 10 objects.
What is the order of executions of the objects ?
Who is the first object executed?
Portal executed all the objects in the first area and then started with the second area?
Which is the first area? these at the top-left corner of the page?
Thank.

8.3.1 Managed Portlet Execution per Page
The PPE(Paralel Page Engine) uses the concept of fetcher threads. These are threads within the PPE servlet which are used to service requests for portlet content. By default there are 25 fetcher threads within the PPE waiting to service requests. If a page has 26 portlets and that page is requested then 25 of the portlets will be requested in parallel and the 26th request will wait for the next available fetcher thread.
This serialization effect will ultimately slow down the portal performance as more requests are received. This degradation will affect the whole portal site, to combat this at a more granular page level OracleAS Portal introduces a feature called Managed Portlet Execution (MPE).
This feature provides a throttle effect similar to fetcher threads but on a per-page basis. If a page has 25 portlets 20 will run the other 5 will wait for free slots then they will run, in effect they'll be throttled.
MPE is set to 20 by default, but this is a configurable parameter allowing administrators to ensure that the performance of the whole site is not degraded by over-zealous page designers putting excessive quantities of portlets on one page.
Link:[http://www.deakin.edu.au/its/dba/oracle-doco/9.0.4.1/9.0.4_doc_library/core.904/b12223/portal.htm#CIHHFCGE]
And parallel means like "all at the sime time" isn't it?

Wi-fi painfully slow on macbook pro in OSX 10.8.2

I have a Mac Book pro and over the last two days my internet has turned painfully slow on wifi - i havent loaded any new programmes and Speedtest shows no problems, still 37mbps on fiber broadband, my iPhone and PC are fine on the same wireless connection and Ethernet is perfect!!
I have tried resetting Safari and Firefox in preferences, clearing history and cookies, resetting DHCP, even using the setting 8.8.8.8. DNS server, and changing wireless channels, resetting the router, as well as running MacScan. I see people talking about turning off IPv6 but im on OS X 10.8.2 and off is not an option I have Automatic, manual and Link-manual only, i have tried all these to no joy still web pages just take ages to load :-( Any ideas?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

DW CS4 painfully slow in W7 64 bit

Hi
I recently built a new core i7 machine with 6GB ram and a solid state hard drive and installed Windows 7 Professional 64 bit on it. I expected it to be very, very fast! Most apps run fine but Dreamweaver CS4 is unusably slow. Every action which involves interraction with windows is painfully slow. Starting the app it takes 20 secs before a splash screen and then another minute before the panels have fully loaded. Opening files takes up to a minute, I've just updated a Library item but can't get it to apply that item to 5 pages.
Previously I was on Vista Ultimate 32 bit with my 3 year old Intel Core Duo machine and CS4 ran fine at perfectly usable speeds.
I've tried setting the app to run in Win XP SP3 mode, no difference.
I've run Adobe updater, there are no updates to be had.
I suspect a problem with the aero interface, but my drivers are all up to date.
Maybe the problem arises from running a 32 bit app on the 64 bit OS?
I use Kaspersky Internet Security 2010, tried running whilst that was disabled, same problem.
I'm at my wits' end. I do a lot of work on DW, but at the moment it is unusable.
Any help gratefully received......
TP

Having the same issues as well - Win7 Ultimate 64-bit, KIS2010 (9.0.0.736), Dreamweaver CS4. Dreamweaver now takes 1-2 minutes before it launches, once I'm finally able to open a file I'm constantly presented with a (Not responding) notice. I'm not unable to even create simple CSS rules - I create and id, click create new rule button, compound selector dialog window opens, I click Ok - then nothing.
Some form of tech support would be helpful on this issue. I've gone through the Russian forums for Kaspersky but I'm not seeing much beyond continually disabling portions of KIS2010 until magically something might work, or might not. I'm fully aware that Adobe will place the blame on Kaspersky, just as Kaspersky will place the blame on Adobe - that being said, those of us having issues, are we all using KIS2010 and experiencing delays? Or, and this is going to be painfully optimistic of me, has anyone gotten the above combination to actually work?

Production Cube painfully slow when resolving partitioned data

Hi,
We have a few 10g cubes in our production environment on Unix servers. For the most part the users are very satisfied with the response time. Most are of a similar design Global Composites, compressed around 9 dimensions.
Recently we introduced a new cube and took advantage of the Parallell processing
feature and partitioned it on the month level of time . It has 9 dimensions (see portion of load log below for specifics). All dimensions are sparse , global composites, Compression, 15 measures .. Most dimensions are aggregated fully or 1 below the top with the exception product aggregated only to the leaf level.
The load works fine 9million data rows loaded and aggregated in 2 hours. The problem we are having is in the response time to a query. It's fine when only 1 month is selected. When you select qtr and years the query becomes painfully slow. When selecting 1 measure for 1 month it takes about 15 seconds to return. When selecting the same measure for the year or qtr it takes about 6 minutes to return. The same is true when I run a report from the Olap worksheet using olap DML so i know that it has nothing to do with the front end or network.
Any ideas on what could be causing the bottleneck in summing the partitions or on how to diagnose the problem. Version is 10.2.0.2
There are only 7 months in the cube and it's 25gb.
thx
Mike

Watrost makes some very valid points and you should review the suggestions he has made.
In addition I would like to add the following. When deciding on how and when to use partitioning and parallel processing I would suggest considering these points:
1) The partition dimension - most people partition on time, probably because all the examples I have seen in this area show this as if it were the "normal" method. Using time is a good idea if you want to perform some form of rolling time window and need to quickly and easily drop data for a specific time period. However, partitioning does impact on query performance and you need to balance the needs of "ease of maintenance" against query performance for your users. Once you have selected a level to use as the partition key you will notice on the Summary tab that levels above this key are in fact grayed out and cannot be selected. As Watrost points out, the partition key in effect becomes your top level of pre-aggregation. All other levels are summed at query time. This is normally ok, but for a 9 dimensional model it means you have no summary levels computed across any of your other 8 dimensions for levels above the partition key. This will have a serious impact on your query performance.
2) Parallel processing - many people seem to implement partitioning in the expectation that their cubes will aggregate more quickly. In most cases this can be true but there are many factors to consider. To be really effective you need to have multiple CPUs, and you should set the number of parallel jobs to a maximum of No of CPUs-1. For some reason I have seen many DBAs just randomly pick a number for this value that greatly exceeds the number of CPUs and then wonder why their cube build takes such a long time. I would start by using the No of CPUs/2 and scaling up to No of CPUs-1 to determine the sweet spot for your system based on resources. Don't forget it is not just CPUs that are important in this situation you also need fast disks as I/O contention can occur very easily.
3) Partial vs Full aggregation - If you upgrade to the latest 10.2.0.3 patcheset and apply the OLAP A Patch as well (available from Metalink) which will allow you to take advantage of partial aggregation features. When loading data into a cube you should only aggregate data for incoming values rather than re-aggregating data for the whole cube. Although AWM does provide a radio button to control this on the second page of the maintenance wizard it is only with the above patchsets that this actually works.
4) Sortarea size : check your sortarea size. Typically, this is set very small in most instances and OLAP operations are very sort intensive. Therefore, increasing this to 1M or higher can have a significant impact on load performance.
5) Monitoring Builds - There are some free performance views you can download from OTN that will help you monitor what is happening during a build. See the link for SQL Scripts for OLAP DBAs and the associated readme at:
http://www.oracle.com/technology/products/bi/olap/OLAP_DBA_scripts.ZIP
http://www.oracle.com/technology/products/bi/olap/OLAP_DBA_README.htm
I would look at the views AW_WAIT_EVENTS, OLAP_PGA_USE and AW_LONGOPS as well as generally monitoring your instance via OEM using the ADDM reports that can be generated. These will help you discover performance bottlenecks in your system
Now for the dilemma - parallel processing vs partitioning. Most people would agree that partial aggregation is a good idea as there is no need to re-aggregate a complete cube when there have been no changes to the dimensions/hierarchies and you are loading data for just the current month. But if you partition by month you will never get parallel processing because you will only be aggregating data within a single partition and for parallel processing to occur aggregation must occur across multiple partitions. What it does mean is that the time take for each load and partial aggregation should be consistent which makes it easy to plan.
If this is proving to be a significant problem then it is possible to use partitioning and generate a fully solved cube. In 11g this will be resolved using a new aggregation feature. For 10gR2 it is possible to create this type of solution. In fact I have just re-designed a customers physical data model to reduce the query time for one of their main user reports from 14 minutes to 10 seconds. The problem was the query accessed the data within the partition that was not aggregated.
It is quite a simple process and does not change your current logical data model. Quite simply you create a surrogate partition dimension with only one two levels - All and "Level 1". Partition on "Level 1". If you are using time, which most people do, level 1 contains all the values for all months, all quarters and all years. Next create a source table that contains using GROUPING SETS to compute totals for months, quarters and years only for base levels across all your other dimensions. This will created an embedded total fact table for your surrogate time dimension.
In the mapping editor, map the surrogate time dimension column in the fact table to your surrogate dimension "Level 1". In the Rules tab within AWM set the aggregation for this surrogate dimension to "Do not Aggregate". Load your data.
In your existing cube you replace your existing stored measures with calculated measures, using the same name, that point to the new physical cubes via a QDR from the standard time dimension to the surrogate time dimension.
Hope this helps.

Good Spec Mac Mini got painfully slow

Hi All
Following reading posts on this forum, I have upgraded my 2011 Mac Mini from 4gb to 8gb Memory, but it is still painfully slow, with the spinning beach ball always in play.
I now have a Core i7, 2.7ghz Mac Mini, with 8GB DDR3 memory, 500 mb disc (with 300gb free), running OSX 10.9.1. I run Microsoft office and Iphoto and thats pretty much it, but even using Iphoto can take seconds for ecah photo to move, and typing emails often means waiting for the text to catch up with my typing.
In my frustration I copied everything off, re formatted the hard disc, and re installed everything, but its still the same speed. The Activity monitor shows very little CPU activity, although the memory shows as 7.87GB used out of 8GB, not sure if that is normal.
Any ideas would be really welcome, as its getting very frustrating to use, when I first purchased the MAC mini it was blindingly fast on everything.
Thanks
Martyn

If you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary on general principle, not because of anything suggested in this comment. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The procedure will help identify which such modifications you've installed, as well as some other aspects of the configuration that may be related to the problem.
Don’t be alarmed by the seeming complexity of these instructions — they’re easy to carry out. Here's a brief summary: In each of two steps, you copy a line of text from this web page into a window in another application. You wait about a minute. Then you paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is copy; paste; paste again. That's all there is to it. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken while booted in “normal” mode. If the system is now running in safe mode and is bootable in normal mode, reboot as usual. If it only boots in safe mode, use that.
Below are instructions to enter UNIX shell commands. They do nothing but produce human-readable output. However, you need to think carefully before running any program at the behest of a stranger on a public message board. If you question the safety of the procedure suggested here — which you should — search this site for other discussions in which it’s been followed without any report of ill effects. If you can't satisfy yourself that these instructions are safe, don't follow them.
The commands will line-wrap or scroll in your browser, but each one is really just a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it.
If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. Step 1 should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
PB=/usr/libexec/PlistBuddy; PR () { [[ "$o" ]] && o=$(sed 's/^/   /' <<< "$o") && printf '\n%s:\n\n%s\n' "$1" "$o"; }; PC () { o=$(grep [^[:blank:]] "$2"); PR "$1"; }; PF () { o=$($PB -c Print "$2" | awk -F'= ' \/$3'/{print $2}'); PR "$1"; }; PN () { [[ $o -eq 0 ]] || printf "\n%s: %s\n" "$1" $o; }; { system_profiler SPSoftwareDataType | sed '8!d;s/^ *//'; o=$(system_profiler SPDiagnosticsDataType | sed '5,6!d'); fgrep -q P <<< "$o" && o=; PR "POST"; o=$(($(vm_stat | awk '/Pageo/{sub("\\.",""); print $2}')/256)); o=$((o>=1024?o:0)); PN "Pageouts (MiB)"; s=( $(sar -u 1 10 | sed '$!d') ); [[ ${s[4]} -lt 90 ]] && o=$( printf 'User %s%%\t\tSystem %s%%' ${s[1]} ${s[3]} ) || o=; PR "Total CPU usage"; [[ "$o" ]] && o=$(ps acrx -o comm,ruid,%cpu | sed '2!d'); PR "Max %CPU by process (name, UID, %)"; o=$(kextstat -kl | grep -v com\\.apple | cut -c53- | cut -d\< -f1); PR "Loaded extrinsic kernel extensions"; o=$(launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)|\.[0-9]+$/{print $3}'); PR "Loaded extrinsic user agents"; o=$(launchctl getenv DYLD_INSERT_LIBRARIES); PR "Inserted libraries"; PC "cron configuration" /e*/cron*; o=$(crontab -l | grep [^[:blank:]]); PR "User cron tasks"; PC "Global launchd configuration" /e*/lau*; PC "Per-user launchd configuration" ~/.lau*; PF "Global login items" /L*/P*/loginw* Path; PF "Per-user login items" L*/P*/*loginit* Name; PF "Safari extensions" L*/Saf*/*/E*.plist Bundle | sed 's/\..*$//;s/-[1-9]$//'; o=$(find ~ $TMPDIR.. $ -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 $ | wc -l); PN "Restricted user files"; cd; o=$(find -L /S*/L*/E* {,/}L*/{A*d,Compon,Ex,In,Keyb,Mail/Bu,P*P,Qu,Scripti,Servi,Spo}* -type d -name Contents -prune | while read d; do ID=$($PB -c 'Print :CFBundleIdentifier' "$d/Info.plist") || ID=; ID=${ID:-No bundle ID}; egrep -qv "^com\.apple\.[^x]|Accusys|ArcMSR|ATTO|HDPro|HighPoint|driver\.stex|hp-fax|JMicron|microsoft\.MDI|print|SoftRAID" <<< $ID && printf '%s\n\t(%s)\n' "${d%/Contents}" "$ID"; done); PR "Extrinsic loadable bundles"; o=$(find /u*/{,*/}lib -type f -exec sh -c 'file -b "$1" | grep -qw shared && ! codesign -v "$1"' {} {} \; -print); PR "Unsigned shared libraries"; o=$(system_profiler SPFontsDataType | egrep "Valid: N|Duplicate: Y" | wc -l); PN "Font problems"; for d in {,/}L*/{La,Priv,Sta}*; do o=$(ls -A "$d"); PR "$d"; done; } 2> /dev/null | pbcopy; echo $'\nStep 1 done'
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
The command may take up to a few minutes to run, depending on how many files you have and the speed of the computer. Wait for the line "Step 1 done" to appear below what you entered. The output of the command will beautomatically copied to the Clipboard. All you have to do is paste into a reply to this message by pressing command-Vagain. Please don't copy anything from the Terminal window. No typing is involved in this step.
Step 2
Remember that you must be logged in as an administrator for this step. Do as in Step 1 with this line:
PR () { [[ "$o" ]] && o=$(sed 's/^/   /' <<< "$o") && printf '\n%s:\n\n%s\n' "$1" "$o"; }; { o=$(sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|calendarse|cups|dove|isc|ntp|post[fg]|x)/{print $3}'); PR "Loaded extrinsic daemons"; o=$(sudo defaults read com.apple.loginwindow LoginHook); PR "Login hook"; o=$(sudo crontab -l | grep [^[:blank:]]); PR "Root cron tasks"; o=$(syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail -n25 | awk '/:/{$4=""; print}'); PR "Log check"; } 2>&- | pbcopy; echo $'\nStep 2 done'
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
You can then quit Terminal. Please note:
☞ Steps 1 and 2 are all copy-and-paste — type only your login password when prompted.
☞ When you type your password, you won't see what you're typing.
☞ If you don’t have a password, set one before taking Step 2. If that’s not possible, skip the step.
☞ Step 2 might not produce any output, in which case the Clipboard will be empty. Step 1 will always produce something.
☞ The commands don't change anything, and merely running them will do neither good nor harm.
☞ Remember to post the output of both steps (unless you had to skip Step 2.) It's already in the Clipboard after you complete each step. You don't have to copy it. Just paste into a reply
☞ If any personal information, such as your name or email address, appears in the output of either command, anonymize it before posting. Usually that won't be necessary.
☞ Don't post what you see in the Terminal window. The output is copied automatically to the Clipboard.
☞ Don't paste the output of Step 1 into the Terminal window. Paste it into a reply.

Portal Page Response time

Hi All,
Enter the portal page url in IE,
I observed portal page response time using the HTTPWatch, it was taking 6 to 7 mintes to get response .
What are the things to do improve the response time.
Please suggest me possible solutions.
Thnaks,
Venkata Sarvabatla

Too big a topic :). Involves download a profiler (commercial ones like JProbe or OptimizeIt or YourKit or ClearApp or free ones available on a google search) which can profile CPU execution and installing and configuring your JVM to send data to it. Then running the problematic part of your application, the profiler will tell you how long each method call took, how many calls were made, the call graphs etc. Once you know which part of your application is taking time , you would then inspect the code and see what the problem is. Im assuming you have already done your rule of thumb tuning (on VM, OS, DB etc).
Google will give you plenty of examples, the tool you choose will also be important , whether you already have a commercial profiler available to your project , or whether youll need to configure some open source one.
This is my writeup for TPTP (free open source)
http://theworkaholic.blogspot.com/2009/10/profiling-bea-weblogic-portal-apps.html
If you havent profiled/tuned before , i suggest you find someone on your project who has and watch them while they do it. Setting up profilers on app servers and writing tests is somewhat painful the first time around and you can learn much more from someone else.
