Poor performance loading portal

Hi
I have just installed Oracle81EE (8.1.7.1.1) and Oracle9iAS Portal (1.0.2.2.0) on Windows 2000 using the step-by-step guide published in August 2001.
At first everything is fine with reasonable performance. However, after loading 5 languages with the landinst command, the performance of the system is so slow that I am now unable to connect to the portal.
Can someone please let me know what I shold do to fix this?
Thanks
Moriamo

I have best performance when install Database 8.1.7.4 and aplly patch Portal 3.0.9.8.4

Need help troubleshooting poor performance loading cubes

I need ideas on how to troubleshoot performance issues we are having when loading our infocube. There are eight infopackages running in parallel to update the cube. Each infopackage can execute three datapackages at a time. The load performance is erractic. For example, if an infopackage needs five datapackages to load the data, data package 1 is sometimes the last one to complete. Sometimes the slow performance is in the Update Rules processing and other times it is on the Insert into the fact table.
Sometimes there are no performance problems and the load completes in 20 mins. Other times, the loads complete in 1.5+ hours.
Does anyone know how to tell which server a data package was executed on? Can someone tell me any transactions to use to monitor the loads while they are running to help pinpoint what the bottleneck is?
Thanks.
Regards,
Ryan

Some sugegstions:
1. Collect BW statistics for all the cubes. Goto RSA1 and go to the cube and on tool bar - tools - BW statistics. Check thed boxes to collect both OLAP and WHM.
2. Activate all the technical content cubes and reports and relevant objects. You will find them if you search with 0BWTC* in the business content.
3. Start loading data to the Technical content cubes.
4. There are a few reports out of these statistical cubes and run them and you will get some ideas.
5. Try to schedule sequentially instead of parallel loads.

I used YourKit on a project about a year ago. I've used a few other profilers and this one was the simplest to install, configure, and use in my opinion. I was doing basic CPU profiling of a WebLogic Portal application on my machine using YourKit within about a few hours of learning of the existence of YourKit. I used it to find performance bottlenecks and it did the job.

Poor performance when dragging item within a list loaded with images - Flex 4

Hi,
I have a custom built List component that is using a TileLayout. I am using a custom itemRenderer to load images into this list from our server (in this test, 44 images rae loaded). I have enabled dragEnabled and dragMove so that I can move items around within the list. The problem comes when I start dragging an item. The dragging operation is very slow and clunky.
When I move the mouse to drag the item, the dropIndicator does not get refreshed for a few seconds and the movement feels like my PC is lagging pretty badly. I've also noticed that during this time my CPU usage is spiking up to around 25-40%. The funny part is I can scroll the list just fine without any lag at all, but the minute I drag the application starts to lag really bad. I do have some custom dragOver code that I used to override the dragOverHandler of the list control, but the problem persists even if I take that code out. I've tried with useVirtualLayout set to both true and false and neither setting made a difference.
Any ideas as to what could be causing the poor performance and/or how I can go abouts fixing it?
Thanks a lot in advance!

Ahh, good call about the Performance profiler. I'm pretty new to the profiling thing with Flex (haven't used Builder Pro before
the Flex 4 beta) so please forgive me
I found some interesting things running the performance profiler but I'm not sure I understand what to make of it all. I cleared the Performance Profile data when right before I loaded the images into the list. I then moved some images around and then captured the Profiling Data (If I understand Adobe correctly, this is the correct way to capture performance information for a set of actions).
What I found is there is a [mouseEvent] item that took 3101ms with 1 "Calls" (!!!!). When I drill down into that item to see the Method Statistics, I actually see three different Callees and no callers. The sum of the time it took the Callees to execute does not even come close to adding up to the 3101 ms (about 40ms). I'm not sure what I can make of those numbers, or if they are even meaningful. Any insight into these?
The only other items that stand out to me are [pre-render] which has 863ms (Cumulative Time) / 639ms (Self Time), [enterFrameEvent] which has 746ms / 6ms (?!), and [tincan] (what the heck is tincan?) which has times of 521ms for both Cumulative and Self.
Can anyone offer some insight into these numbers and maybe make some more suggestions for me? I apologize for my ignorance on these numbers - as I said, I'm new to the whole Flex profiling thing.
Many thanks in advance!
Edit: I just did another check, this time profiling only from the start of my drag to the end of my drop, and I still see [mouseEvent] taking almost 1000ms of Cumulative Time. However, when I double click that item to see the Method Statistics, no Callers or Callees are listed. What's causing this [mouseEvent] and how come it's taking so long?

Poor Performance in ETL SCD Load

Hi gurus,
We are facing some serious performance problems during an UPDATE step, which is part of a SCD type 2 process for Assets (SIL_Vert/SIL_AssetDimension_SCDUpdate). The source system is Siebel CRM. The tools for ETL processing are listed below:
Informatica PowerCenter 9.1.0 HotFix2 0902 357 (R181 D90)
Oracle BI Data Warehouse Administration Console (Dac Build AN 10.1.3.4.1.patch.20120711.0516)
The OOTB mapping for this step is a simple SELECT command - which retrieves historical records from the Dimension to be updated - and the Target table (W_ASSET_D), with no UPDATE Strategy. The session is configured to always perform UPDATEs. We also have set $$UDATE_ALL_HISTORY to "N" in DAC: this way we are only selecting the most recent records from the Dimension history, and the only columns that are effectively updated are the system columns of SCD (EFFECTIVE_FROM_DT, EFFECTIVE_TO_DT, CURRENT_FLG, ...).
The problem is that the UPDATE command is executed individually by Informatica Powercenter, for each record in W_ASSET_D. For a number of 2.486.000 UPDATEs, we had ~2h of processing - a very poor performance for only one ETL step. Our W_ASSET_D has ~150M records today.
Some questions for the above:
- is this an expected average execution duration for this number of records?
- updates record by record are not optimal, this could be easily overcome by a BULK COLLECT/FORALL method. Is there a way to optimize the method used by Informatica or we need to write our own PL-SQL script and run it in DAC?
Thanks in advance,
Guilherme

Poor performance of BLOB queries using ODBC

I'm getting very poor performance when querying a BLOB column using ODBC. I'm using an Oracle 10g database and the Oracle 10g ODBC driver on Windows XP.
I create two tables:
create table t1 ( x int primary key, y raw(2000) );
create table t2 ( x int primary key, y blob );
Then I load both tables with the same data. Then I run the following queries using ODBC:
SELECT x, y FROM t1;
SELECT x, y FROM t2;
I find that the BLOB query takes about 10 times longer than the RAW query to execute.
However, if I execute the same queries in SQL*Plus, the BLOB query is roughly as fast as the RAW query. So the problem seems to be ODBC-related.
Has anyone else come across this problem ?
Thanks.

Hi Biren,
By GUID, are you referring to the Oracle Portal product?

General poor performance of my Mac mini

I have been using my mac mini for over a year, it continues to frustrate me how slow and unresponsive it can be even though I do very little with it, i.e organise photos and browse the web - usually looking for solutions to the poor performance problem!
I came a cross this app that has given me lots of information, unfortunately with my limited IT know-how there is nothing here that gives me any clues, as to the cause of the problem. I guess the red font is not good?
I'm sorry i can't be more specific about the problem other than to say that iPhoto and Safari the two programmes i use way more often than any other, keep giving me the beach ball. My internet speed is ok 25 Mbps down - 4.5 Mbps
Is there anything here that stands out as being wrong? if so any suggestions/ instructions for what I should do?
p.s. i had to quit Safari while writing this and have a report for this if it helps?
Any help much appreciated.
Problem description:
My mac is just generally very slow. I only use it to look at the internet and manage photos.

Hi Linc Davis
Thank you for taking the time to respond.
I got this information from a time when I was opening up iPhoto, and then going to the iCloud folder. To be honest it wasn't the most disastrous of events, I did get a few beachballs and when I opened up a shared folder the photos weren't loaded as normal. As I get more lengthy delays in carrying out any activities I will post back the console results.
Just as a bit more info, I don't consider my problem an update to Yosemite problem, if anything since updating performance has been improved from Mavericks.
Do you have any comments about upgrading RAM from the 4GB I have?
Should I act on any of the messages in red from the EtreCheck report?
Many Thanks
Duncan

Skype crashing and poor performance

Hello!
I have a Lumia625 with WP8.1. My problem is that Skype has a really poor performance on my phone. It crashes 6 times out of 10 on startup, and even if I manage to start it, the whole app is slow and laggy. Sometimes I can't even write a message it's so laggy. Video call is absolutely out of the question. It crashes my whole phone. I have no similar problems with other instant messaging apps nor with high-end games. There is something obviously using way more resource in the Skype app than it's supposed to. It's a simple chat program, why would it need so much resource?
The problem seems to be originating from the lower (512 mb) RAM size of my phone model, because I experienced the same effect with poorly written apps, that don't keep in mind that there are 512 RAM devices, not only 1GB+ ones, and use too much resource.
Please don't try to suggest to restart/reset the phone, and reinstall the app. Those are already behind me, and they did NOT help the problem. I'm not searching for temporary workarounds.
Please find a solution for this problem, because it is super annoying, and I can't use Skype, which will eventually result in me leaving Skype.
Solved!
Go to Solution.

When it crashes on startup it goes like:
I tap the skype tile
The black screen with the "Loading....." appears (default WP loading screen). Usually this takes longer than it would normally take on any other app.
For a blink of an eye the Skype gui appears, but it instantly crashes.
If I can successfully start up the app, it just keeps lagging. I sart to write a message to a contact, and sometimes even the letters don't appear as I touch them, but they appear much later altogether. If I tap the send message button the whole gui freezes (seems like it freezes till the contact gets my message). Sometimes the lag get stronger, and sometimes it almost vanishes, but if I keep making inputs when the lag is strong, sometimes it crashes the whole app.
When I first installed the app, everything was fine. But after a while this behavior appeared. I reinstalled the app, and it solved the problem temporarily, but after some time the problem re-appeared. I don't know if it's relevant, but there was a time when I couldn't make myself appear online all the time (when the app was not started). In that time I didn't experience the lags and crashes. Anyways, what I'm sure about is that the lags get worse with time. Idk if it's because of use of the app (caching?), or the updates the phone makes to itself (conflict?).
I will try to reinstall Skype. Probably it will fix it for now. I hope the problem won't appear again.

Poor performance of WD Abap/ Adobe

Dear sirs,
I would like to know if anybody of you have experienced very poor performance of WD ABAP with Adobe interactive form. Our client has paid for a 2-3 pages interactive form in WDA and is complaining about very poor performace. As a result no users are using this application because of this poor performance.
Can anybody point out what can be a problem? Some developement problem? Basis issue? Any experience related to WDA Adobe performance? Thank you all, Otto

Update: SAP OSS message was opened regarding this problem.
We got a list of patches to update, notes to apply etc. All was done, applied, patched. The performance didn´t get better, it anything it was like extra percent or two, but nothing what would make the customer less angry.
The result: this technology is promising but a) needs strong client PC b) will get better (i hope gets better soon)
Our basis team checked all the times (of actions that has to be done to load/use the app) and the memory need both on server and client. On some client PCs only the Adobe Rader was starting like a half a minute (and more, not less). If you add time for WD, for WD/ Adobe communication and the data transfer, the time to start working with WD ABAP Adobe app can be more than a minute. That is not very usable.

CS6 poor performance

Hi.
I have a workflow that involves opening several raw files into Camera Raw via Bridge, adjusting the settings, then from Bridge I use the command to open files into Photoshop layers. While that is happening in Photoshop, I go back to Bridge and open the next several files in Camera Raw and make adjustments. When done, the first lot of files will be in layers in Photoshop ready for me to start layer blending.
This worked fine in CS5, but in CS6 it all goes wrong after a few batches of files. Camera Raw is slow to respond to adjustment of sliders and is slow to update to changes in settings. Then I find that Photoshop has aborted the loading of files into layers. I end up with one layer with an empty layer above it. I close this file, but when I quit Photoshop I'm prompted to save a file that I cannot see and is not listed as an open document under Photoshop>Windows.
This is a show-stopper for me, and have reverted to CS5 to get work done. Hoping to find a solution.
Running a MacPro, with 2 x 2.66 GHz Quad Core Intel Xeon processors, 24GB RAM, standard ATI Radeon HD 4870 card that came with the Mac.

A lot of the poor performance of CS6 is linked to the video card and driver. CS6 relies a lot more on the video card than CS5 and also has a new graphics engine. It may take a little longer for ATI and NVidia to get the drivers configured correctly. THe latest 12.4 from ATI is worse than the 12.2. Perhaps the next update will get it right.

Shared nothing live migration over SMB. Poor performance

Hi,
I´m experiencing really poor performance when migrating VMs between newly installed server 2012 R2 Hyper-V hosts.
Hardware:
Dell M620 blades
256Gb RAM
2*8C Intel E5-2680 CPUs
Samsung 840 Pro 512Gb SSD running in Raid1
6* Intel X520 10G NICs connected to Force10 MXL enclosure switches
The NICs are using the latest drivers from Intel (18.7) and firmware version 14.5.9
The OS installation is pretty clean. Its Windows Server 2012 R2 + Dell OMSA + Dell HIT 4.6
I have removed the NIC teams and vmSwitch/vNICs to simplify the problem solving process. Now there is one nic configured with one IP. RSS is enabled, no VMQ.
The graphs are from 4 tests.
Test 1 and 2 are nttcp-tests to establish that the network is working as expected.
Test 3 is a shared nothing live migration of a live VM over SMB
Test 4 is a storage migration of the same VM when shut down. The VMs is transferred using BITS over http.
It´s obvious that the network and NICs can push a lot of data. Test 2 had a throughput of 1130MB/s (9Gb/s) using 4 threads. The disks can handle a lot more than 74MB/s, proven by test 4.
While the graph above doesn´t show the cpu load, I have verified that no cpu core was even close to running at 100% during test 3 and 4.
Any ideas?

Hi Per Kjellkvist,
Please try to change the "advanced features"settings of "live migrations" in "Hyper-v settings" , select "Compression" in "performance options" area .
Then test 3 and 4 .

Poor performance of managed workstation devices

Hi all togehter,
we have big problem with the speed of the ZCC, when I click view details by a managed workstation device.
It takes up to 60 seconds until the ZCC show me the details for the selected device.
Even if I click on the inventory, relationships and so on, it takes soooo long. But the poor performance is only at the Workstation devices not at the Server devices.
Or environment is:
ZCM 11.2.4
Oracle RAC 11.2.0.4 Database
Primary Server SUSE Linux Enterprise Server 11 on ESX 4
1800 managed devices
Thank you for your help
Stefan

Originally Posted by dbriese

Although this is actually a step before displaying a device's details the list view seems to have an impact on it.
We had some issues with performance (11.2.x) until we set the ZPM dashboard and trending down to 7 days (from 30). But if you're on Oracle be careful if you do that because the script that Novell uses doesn't do the purging in batches. It does them all and THEN issues a COMMIT. This, of course, makes Oracle write all the non-committed stuff to the logs, and can fill up a lot of disk space.
Anyway, once we did that, we're at over 4,000 managed workstations and I can pull up an entire list of workstations in under 30 seconds (1,000/page is the max).
We're on Oracle, but not RAC.
Currently on 11.3.2 on SLES 11 SP3 64-bit on VMware ESXi 5.1
We have tuned the primaries for the JVM memory ballooning as per the the VMware docs.

WAD-Analysis Item-Poor performance for new lines

Hi.
I use WAD7 for entering new records in IP.
According to our business requirements, in analysis item properties I have defined "Number of New Lines in Planning Queries" = 50.
After that I face before extremely poor performance - it takes about 1-2 minutes until the page has loaded (note that it is empty page - only new blank rows).
When I define new lines = 1 performance is very good (2-3 sec).
Does anybody know what could be the problem ?
Thanks.

Hello Andrey,
the number of new lines configured in WAD is completely unknown in the ABAP backend and has no impact on backend performance; in fact, the front end gets information about one 'line' of template cells, this costs nothing.
Checks for characteristic relationships etc. only may have significant costs for cells of the result set, not for new lines.
Whether this problem comes from the ABAP backed or form the Java stack or from the browser rendering can be checked
with an RSTT trace. Is the run time of the trace different between 1 or 50 new lines, were different backend calls recorded?
If not, the problem comes from the Java stack or from the browser rendering. One can check the latter via task manager.
To check (partially) the run time in Java and/or ABAP stack add the parameter &PROFILING=X in the url, cf. note 1048691.

Gregor

Non jdriver poor performance with oracle cluster

Hi,
we decided to implement batch input and went from Weblogic Jdriver to Oracle Thin 9.2.0.6.
Our system are a Weblogic 6.1 cluster and an Oracle 8.1.7 cluster.
Problem is .. with the new Oracle drivers our actions on the webapp takes twice as long as with Jdriver. We also tried OCI .. same problem. We switched to a single Oracle 8.1.7 database .. and it worked again with all thick or thin drivers.
So .. new Oracle drivers with oracle cluster result in bad performance, but with Jdriver it works perfectly. Does sb. see some connection?
I mean .. it works with Jdriver .. so it cant be the database, huh? But we really tried with every JDBC possibility! In fact .. we need batch input. Advise is very appreciated =].
Thanx for help!!

Thx for quick replys. I forget to mention .. we also tried 10g v10.1.0.3 from instantclient yesterday.
I have to agree with Joe. It was really fast on the single machine database .. but we had same poor performance with cluster-db. It is frustrating. Specially if u consider that the Jdriver (which works perfectly in every combination) is 4 years old!
Ok .. we got this scenario, with our appPage CustomerOverview (intensiv db-loading) (sorry.. no real profiling, time is taken with pc watch) (Oracle is 8.1.7 OPS patch level1) ...
WL6.1_Cluster + Jdriver6.1 + DB_cluster => 4sec
WL6.1_Cluster + Jdriver6.1 + DB_single => 4sec
WL6.1_Cluster + Ora8.1.7 OCI + DB_single => 4sec
WL6.1_Cluster + Ora8.1.7 OCI + DB_cluster => 8-10sec
WL6.1_Cluster + Ora9.2.0.5/6 thin + DB_single => 4sec
WL6.1_Cluster + Ora9.2.0.5/6 thin + DB_cluster => 8sec
WL6.1_Cluster + Ora10.1.0.3 thin + DB_single => 2-4sec (awesome fast!!)
WL6.1_Cluster + Ora10.1.0.3 thin + DB_cluster => 6-8sec
Customers rough us up, because they cannot mass order via batch input. Any suggestions how to solve this issue is very appreciated.
TIA

It's much faster than any 9.X

Poor Performance with Fairpoint DSL

I started using Verizon DSL for my internet connection and had no problems. When Fairpoint Communications purchased Verizon (this is in Vermont), they took over the DSL (about May 2009). Since then, I have had very poor performance with all applications as soon as I start a browser. The performance problems occur regardless of the browser - I've tried Firefox (3.5.4), Safari (4.0.3) and Opera (10.0). I've been around and around with Fairpoint for 6 months with no resolution. I have not changed any software or hardware on my Mac during that time, except for updating the browsers and Apple updates to the OS, iTunes, etc. The performance problems continued right through these updates. I've run tests to check my internet speed and get times of 2.76Mbps (download) and 0.58Mbps (upload) which are within the specified limits for the DSL service. My Mac is a 2GHz PowerPC G5 runnning OSX 10.4.11. It has 512MB DDR SDRAM. I use a Westell Model 6100 modem for the DSL provided by Verizon.
Some of the specific problems I see are:
1. very long waits of more than a minute after a click on an item in the menu bar
2. very long waits of more than two minutes after a click on an item on a browser page
3. frequent pinwheels in response to a click on a menu item/browser page item
4. frequent pinwheels if I just move the mouse without a click
5. frequent messages for stopped/unresponsive scripts
6. videos (like YouTube) stop frequently for no reason; after several minutes, I'll get a little audio but no new video; eventually after several more minutes it will get going again (both video and audio)
7. response in non-browser applications is also very slow
8. sometimes will get no response at all to a mouse click
9. trying to run more than one browser at a time will bring the Mac to its knees
10. browser pages frequently take several minutes to load
These are just some of the problems I have.
These problems all go away and everything runs fine as soon as I stop the browser. If I start the browser, they immediately surface again. I've trying clearing the cache, etc with no improvements.
What I would like to do is find a way to determine if the problem is in my Mac or with the Fairpoint service. Since I had no problems with Verizon and have made no changes to my Mac, I really suspect the problem lies with Fairpoint. Can anyone help me out? Thanks.

1) Another thing that you could try it is deleting the preference files for networking. Mac OS will regenerate these files. You would then need to reconfigure your network settings.
The list of files comes from Mac OS X 10.4.

2) I think it is time to do a clean install of your system.
3) It's either the software or an intermittent hardware problem.
If money isn't an issue, I suggest an external harddrive for re-installing Mac OS.
You need an external Firewire drive to boot a PowerPC Mac computer.
I recommend you do a google search on any external harddrive you are looking at.
I bought a low cost external drive enclosure. When I started having trouble with it, I did a google search and found a lot of complaints about the drive enclosure. I ended up buying a new drive enclosure. On my second go around, I decided to buy a drive enclosure with a good history of working with Macs. The chip set seems to be the key ingredient. The Oxford line of chips seems to be good. I got the Oxford 911.
The latest the hard drive enclosures support the newer serial ata drives. The drive and closure that I list supports only older parallel ata.
Has everything interface:
FireWire 800/400 + USB2, + eSATA 'Quad Interface'
save a little money interface:
FireWire 400 + USB 2.0
This web page lists both external harddrive types. You may need to scroll to the right to see both.
http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATAFW800_FW400USB
Here is an external hd enclosure.

Here is what one contributor recommended:
http://discussions.apple.com/message.jspa?messageID=10452917#10452917
Folks in these Mac forums recommend LaCie, OWC or G-Tech.
Here is a list of recommended drives:
http://discussions.apple.com/thread.jspa?messageID=5564509#5564509
FireWire compared to USB. You will find that FireWire 400 is faster than USB 2.0 when used for a external harddrive connection.
