Performance slow down (Run Portal Form)

performance slow down
Hi :
When I code a program and running, it is running speed is very fast. but After I was coded programs about 10 program, it is speed is
slow down, runing a program must speed 1 minute.
My portal system totally have 12 programs, when I reinstall portal system. that problem never change.
Can you tell me why? Thanks.
null

Hi :
Sorry, I don't understand your answer.
you mean the solution is create index.
But what table can I create index, oracle portal table or my own apllication table?

JVM performance slowed down after

Hello all,
My java application is heavily multithreaded and its supposed to run as a 24/7 service. Its supposed to collect SMS from different servers, store in memory/flat-files and send them to clients.
The application has been running for the past 6 days and
the JVM has slowed down considerably. (performance has gone down)
Initially the app used to receive/send arnd 50 SMS per second and now it process aroubd 20-25 SMS per second.
I've been using Your kit profiler to profile my app.
The maximum heap I allocated was 500MB; the alloted Heap shown in the
profiler is 95MB and the used Heap is 65MB
The CPU usage looks fairly stable,i.e. it does go up when SMS comes in
and i/o operations takes place and goes to 0% when no process is being done.
memory usage also looks fairly stable.
(No explicit memory leaks)
The application has over 133 threads and that stays the same as per
the profiler tool kit.
Also in my application I have a maintainance phase at 23:00 hours during which i do some cleaning work like
-deleting of expired SMS from memory
-deleting old log files
-deleteing other flat files
-and finally I explicitly call the garbage collector
What should I look in - to maintain the performance, should I not explicitly call
the GC and let JVM do it on its own? or is it beacause the heap space has become fragmented? - I do make a lots of read/writes from/to the objects stored in Heap.
I also make around 160,000+ read/write from/to flat files in the hard disk.
Could this cause the JVM to slow down?
Any suggestion on this will be great.

Initially the app used to receive/send arnd 50 SMS
per second and now it process aroubd 20-25 SMS per
second.
I've been using Your kit profiler to profile myapp.
Does it have CPU profiling? If yes, then you can look
at where the time's being spent when processing a
message.
It does have a CPU profiling graph, but there is nothing much i can infer from it, I can see the graph peaking to 60-80% CPU usage when SMS are comming in (i.e. SMS is received, stored in memory & a copy is also put in the flat file - which is a read/write I/O operation, so I would defenitely expect the CPU to peak up); this peaking up would normally happen between 6-9am when lots of SMS come it to my app. The rest of the time (in the afternoon & evening) CPU is 0% ; so I can defenitely rule ot memory leak right?
its difficult to find out the time taken to process every message; the rough estimate I got from the log file is 50SMS / Sec. i.e. 50SMS receievd via TCP/IP; then store it in flat file & memory and also deliver it across to a client via socket; get a response back; change some status in memory and also in the flat file; this count of 50 has defenitely dropped to 25-30 in 6 days.

So not a memory problem.
The CPU usage looks fairly stable,i.e. it does goup
when SMS comes in and i/o operations takes place
and goes to 0% when no process is being done.So not a background thread that's run amok
(probably).
The application has over 133 threads and thatstays
the same as per the profiler tool kit.You could be running into contention for a shared
resource. This will show up in the CPU profiler, or
you can get a "quick and dirty" report by hitting
Ctrl-\ in the window where the JVM is running (or, if
on Unix, sending SIGQUIT to the JVM process). This
will send a thread dump to the console. Look for a
lot of threads "wait"ing on some object, then look
for the thread that holds that object.
You are talking of possible dead-locks right? thats something i@ve go to llok into; the profiler does lists ot a list of possible thread-deadlocks. but all of them are purposefully made into TIMED_WAITING ; would that cause the performance to drop?
>

Never call GC directly. The JVM will do it when
necessary. Plus, you don't appear to have a memory
issue.
Yep, would change that and avoid calling GC directly.
>
I also make around 160,000+ read/write from/toflat
files in the hard disk. Could this cause the JVM toslow down?
Ahh ... flat files in a single directory? A lot of
files in one directory will definitely slow things
down, especially if you're opening them for every
read and write: the OS has to scan the entire
directory to find the file.Nothing much I can do there.
>
Does performance improve after your nightly cleanup?
If yes, and you're removing old files, then this is
an indication of the problem.I'll look into the logs to see if there is any increase in performance after GC and clome back

Performance slows down when moving from stage to test schema within same instance with same database table and objects

We have created a stage schema and tested application which is working fine when we are moving it to another schema for further testing ( This schema is created using same scripts which were used to create objects in staging schema) the performanc of application (Developed in .NET) slows down drastically
Some of the store procedures we have checked at Databse/SQLdeveloper level are giving almost same performance but at Application level there is lot of difference
Can you please help
We are using Oracke 11g Database

Are you using the Database Cloud Service? You cannot create schemas in the Database Cloud Service, which makes me think you are not. This forum is only for the Database Cloud Service.

Why does Firefox performance slow down after starting Jack server?

Hello,
I started configuring my audio on my system. So, I want to have jack working (not jack2, to work with wineasio) with best sound quality with all sound routed through jack. When i start jack server with this command and settings:
killall jackd;killall pulseaudio;jackd -R -t 1000 -d alsa -P hw:0,0 -r 48000 -n2 -D
Firefox slows down, opens new pages slow and the scroll down is very very slow. I had this issue with other distros too. I suspect that it has to do with realtime ( which i need for my audio related apps like traktor through wine, ardour, ableton through wine etc) without being sure about it. Any idea why this is happening?

zabrielza wrote:I had this issue with other distros too.
This smells like hardware problem. Do this:
1. Kill pulseaudio, jack, and make sure they are killed
2. Make sure you do not renice anything or apply other such tweaks
3. Run jackd -d alsa
4. Use your system
5. If unsatisfactory, try jackd -d alsa -p 1024 -n 3
6. Use your system
Jack runs with realtime priority by default (no flag required), and we still use the audio group to provide that privilege. I also do not advocate the realtime kernel, but you may try it. Jack not functioning well (i.e. hampering other tasks significantly) on a standard kernel is cause for concern.
You can read/grep your dmesg and systemd journal for suspicious messages. You may try running real-time audio tasks in another operating system with your hardware, and upon success may proceed to debug the problem on Linux, possibly with the help of the alsa developers.
Or better yet, grab a supported semi-pro external audio device if jack is important for you. However, this may not help if the problem is somewhere deeper, e.g. at the hardware interrupt level.

System and performance slowing down even after Diskwarrior use?

i own a G5 Powermac
it seems to be getting slower. i have had it a year and a half. i have 2 G ram and it is a dual processor so i don't really understand why it should be going more slowly at all. I don' even burden it with heavy duty programs like Final cut because it is not right in the head.
what do you recommend?
does this happen often?
any ideas?
mediusCentral

Mac's get slower the more the boot drive is filled past 50% and really slow when nearly full.
Keep your boot drive less than 80% and ideally less than 50% filled.
Learn to clone your boot drive to a external drive and back again, this will optimize the drive and increase performance as Mac OS X is constantly accessing the boot drive for something or another.
You'll need a cloning software that will copy the entire drive, just copying folders won't work due to invisible and locked system files.

Performance slowing down when ripping cd's..external drive won't work

2 problems I need help with. Itunes was ripping my cd's to wav format anywhere from 20-40x from my internal cd/dvd player/burner. Now it's only doing it around 12x. I cleaned up space and defraged the hard drive, but that didn't help. I also upgraded to the latest version of itunes (which took me 2 days to fix..that's another discussion completely). Still didn't help. I then tried using the external player cd/dvd player/burner. The cd is recognized by itunes, but will not rip the file. It goes through the files very quickly and leaves filenames on my hard drive, but the files are empty.
So what's killing the speed on my internal drive and how come I can't rip from the external drive?
Thanks to anyone who can help.

You'd have to rule out the possibilities. By connecting the drive to another Mac using the same cable, it seems like you have ruled out the drive itself and the cable.
The two remaining possibilities I can think of are the iMac's FireWire 400 port being faulty and a software-related cause.
To rule out the software cause, you can try starting up from your Mac OS X installation disc; insert disc and restart with the C key held down. When you get to Installer's first screen, go up to the menu bar. Under Utilities, select to run Disk Utility. Connect the external drive. Does it appear in the Disk Utility sidebar properly, as a drive with a volume indented below? If it does, there may be some problem with your currently installed system that is causing this problem. If it does not, then it becomes more likely that there is some hardware-related problem with the iMac's FireWire port.
Note: When you did the "unplugging everything for half an hour," you should use the reset SMC procedure instead. Try following this procedure precisely.
http://support.apple.com/kb/HT3964
When you do this, you should disconnect ALL cables. If you have been using a power strip, connect the power cord directly to a wall power outlet for this test. Power it up with nothing connected, except for the power cord. Then, add only your keyboard/mouse. Connect the external drive. Is there any difference?
Also consider how the external drive is connected to power. Is it connected to power differently when it works on the MacBook? Were you using a crowded power strip that also has the iMac's power cord? As with the iMac itself, if you have been using a power strip, try connecting the hard drive's power cord directly to a wall power outlet for this test.

MacBook Pro 13" Late 2011 Experiencing Significant Slow Down After Boot Camp Installation

     Okay, so today, after installing Windows 7 on my MacBook Pro via Bootcamp Assistant, I experienced significant performance slow down (fans going at full blast, applications opening after extended periods of time, keystrokes not being registered) when I returned to my OS X partition/second hard drive. I have dual hard drives, one of them being a Samsung 256 GB SSD with OS X Mavericks and the other being my original 500 GB HDD, divided into a 250 GB OS X Mavericks partition and a 250 GB Windows partition. I have the SSD set as my startup disk and I have it located in the main HDD bay. I moved the old HDD into a caddy and placed it where the optical drive normally should be.
      After multiple failed attempts to install Windows via USB and Bootcamp Assistant, I decided to reinstall my optical drive and use a Windows installation disk. This attempt proved successful, and I was able to install Windows 7 onto the 250 GB partition I had created for it on the 500 GB HDD. After completing basic setup of Windows, I removed the optical disk drive and reinstalled the SSD and the HDD into their original spots (SSD in the main HDD bay, HDD in the caddy where the optical drive normally is).
     After completing this tedious process, I booted my Mac back up using the SSD. However, I noticed something was wrong when the login screen, apps, and nearly everything else on my desktop had slowed to crawl. I decided to check my Activity Monitor to see what the problem might be. Activity Monitor told me that the task "kernel_task" was taking up anywhere from 200-600% of my CPU, which explained the slowdown in performance. I looked around to see if there were others with the same problem as me, and I found that Spotlight Indexing might be an issue, with a potential remedy being move my Bootcamp Partition into the Privacy section of Spotlight under System Preferences. After doing that, I experienced no increase in performance and everything was still going very slowly.
     The next step I took was to see if booting into Safe Mode would help the issue. After booting into Safe Mode on my SSD, I noticed that things were back to their normal speeds, with applications opening at the speed they should be and keystrokes being registered instantaneously. However, the fans were still going and had not shut off once booting into Safe Mode. In addition, I checked Activity Monitor and the "kernel_task" in question was no longer taking up massive amounts of the CPU.
     At this point, I don't know what to do and I need help in restoring my Mac to original speeds. I may end up deleting my Boot Camp partition as a last measure if all else fails, seeing as I installed Windows in the first place for running a few programs and games that I can live without. However, I'd prefer to not have things come to that and fix things before deleting the Boot Camp Partition. I've heard that if everything runs normally in Safe Mode, then the issue is third-party software. Is this true?
     Any help would be greatly appreciated as I am writing this from the MacBook in question in Safe Mode because it's essentially useless in normal SSD operation.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
Copy a line of text in this window to the Clipboard.
Paste into the window of another application.
Wait for the test to run. It usually takes a few minutes.
Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is 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, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in 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.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.

LR 2.5 slows down after upgrading to Snow Leopard

This is my first post, so first of all I'd like to say hello to everybody here and apologize for my poor english
My computer is an iMAC with an Intel Core 2 Duo, 4GB RAM, 500GB HD and a graphic card NVIDIA GeForce 8800 GS with 512 MB VRAM.
The LR database is contains, up to now, about 5000 photos most of them in NEF format (my camera is a Nikon D300)
In the last month I noticed that the performance slowed down consistently as thumbnails refresh started taking a long time as well as editing photos and the overall LR2 (executing at 64bits) working.
I started monitoring the system, but despite the low LR2 performances I still had a lot of free RAM and the cores weren't really working a lot.
I can't say this for sure, but I could bet that the performance problems began with the upgrade to Snow Leopard.
Can anybody help me to solve this issue?
Thanks a lot in advance

Lightroom performance should not have deteriorated as a result of upgrading to Snow Leopard. Things that you should check are:
1. that you are indeed running Lightroom in 64-bit mode (open System info under Help menu and check that Application Architecture shows x64)
2. that you have all of your previews rendered to at least Standard-size
3. that you have at least 20% free hard disk space
You should also run the Catalog Optimisation option in Catalog Settings
1. Yes, LR2 was running in 64 bit mode before upgrading to Snow Leopard, then (don't know why) gets back to 32 just after the upgrade and I manually set it to 64 bit (checked in the application and on the process monitoring while running)
2. I have the preview rendered 1:1 in the folder I'm working on (done again tonight)
3. I have 55% free HD space
4. I run a Catalog Optimization many times, The last one was tonight
In other words I've checked and tried all these things many times. I've red on the internet that it might be a geforce 8800 issue, but I've found only windows references. Don't forget that neither RAM nor CPU are stressed when LR2 is working and all other applications run normally

Has anybody else noticed a 10-25% openGL slow down with 10.7.5?

Hi, I was running x-plane 9.70 at certain settings on my 17" MBP (early 2011, 10.7.3) and noticed I was getting about 70 fps... nice. I do an update on firmware and OS (10.7.5) and I notice that the x-plane fps has dropped to about 55. The settings and environment the same as near as I can get. I thought this was bad but maybe just x-plane or something peculiar. I also couldn't tell if the performance drop was caused by the firmware update or the OS update.
I remembered I'd done an xbench benchmark with 10.7.3 so I did a new one with the updates... sure enough the openGL numbers had dropped by 20% or so. So, I hooked up my backup drive with 10.7.3 on it and ran x-plane and xbench again to try to isolate the firmware update from the OS update.... The results were x-plane still showed a drop of about 10% and xbench about 25%. Looks like there is something wrong in 10.7.5.
Has anybody else noticed a performance slow down in openGL functions with 10.7.5?
Khan

Thank you for this first reply! I'll have to give this a try later....the main laptop I experience this on crashed not more than an hour after I posted this issue. I'm on a tiny, slow netbook that hasn't had the same problem. Now I'm wondering if I picked up a Trojan on the main laptop and the "Not Responding" message is a side effect of a virus or Trojan.
One of the system .dll files has been corrupted and I'm not being allowed to use recovery discs, previous disc images, or any recovery options. That was an all day sucker yesterday and from what I've read on forums and have researched, it appears I'm going to need to reload the operating system. If it is indeed a Trojan/virus, I'm surprised it made it through my antivirus and firewall. Anything is possible, really.
Thanks again, I'll get back with results once I get the wounded laptop back up and running.

Portal Forms Perfomance

I have developed several forms using 10.1.2 Portal. I have tried both a view based form and a table base form. Both the view based and the table based forms work but are very slow...I count 8 sec to comeback with results from the a simple table in the database. Simple I mean one table with about ten columns...with about ten rows of data in it. Can somebody please point me in the direction of performance tuning specific to Portal Forms? I have scrubbed the discussion forms and have not found relavent discussion.
Regards,
David Cryderman

So nobody has ever had any performance issues with Portal and Forms? I am the only one? I guess I am very special.
Help would be greatly appreciated. Hard to find documentation on performance. I am new to portal, so any information would be great.

Is there any advanced feature of Adobe Flash released to lower the page loading slow down rate...?

Any advanced feature of Adobe Flash to embed in my site
Hi! My site is basically based on providing share market tips covering finance market. The site was recently migrated from the old look to a new look for a professional view. To make the home page wear a professional look, I am displaying a video like screen for news headlines organising images into jquery effect. But what I experienced so far this jquery effect is slowing down the home page at the time of loading (plz refer the screen shot below). You can check it at Puntercalls Homepage . I'm sure if I embed the normal flash feature in palce of this jquery, it must slow down than the former.
So what I exactly want to know is if there is any advanced feature of Adobe Flash by which the homepage won't slow down while loading.
Kind suggestions are greatly appreciated in advance!
The screenshot of slower loading as the result of jquery effect:

If you just want to change the way that the photo section works, then, it is most likely that a Flash version of the photo display might be smoother and faster to play than the jquery version that you are now using. Its difficult to guarantee a result. You have 10 css libraries and 8 js libraries that are called along with a good bit of inline js that is running on this site. So it will be difficult to say how quickly or smoothly a Flash .swf file will download and play.
I'm guessing that Flash will be faster, but then I also think that going door to door and handing people a print of the photo would be faster than the jquery file that is running. You may want to look at the possible interference that you have on the current site between the various js and css files that are trying to display the content.

Browser based InfoPath Forms in SharePoint 2010 performance has slowed down after SharePoint 2010 SP2

hi All,
Our Browser based Infopath forms have slowed down drastically after applying SharePoint 2010 SP2. Prior to this, we had SharePoint 2010 SP1 and the timings was around 10 seconds (single user) for the entire infopath form to be displayed which has 10-12
views and 5 data connections and 15 business rules and around 100 fields.
But now after applying sharepoint 2010 sp2, the performance has slowed down and it now takes for a single user around 50 seconds.
Refer to the link below, which we followed by applying the patch as well, but the performance is still the same very slow.
http://social.technet.microsoft.com/Forums/sharepoint/en-US/0b673324-01c4-49f7-86cb-647aa43fefd6/infopath-browser-forms-extremely-slow-after-service-pack-2-upgrade?forum=sharepointadminprevious
We have raised a ticket with Microsoft, but there is no concrete resolution as to what component of the infopath has made the form rendering and display slow.
Can someone point me to the right resource or knowledge base where i can do a kind of debug, which tells me exactly which infopath dlls are the issue or which part of my form is taking more time. I am using AOLPageTest and Fiddler, but they do not give me
any details where exactly is the bottleneck.
Any tools that give me the details of the bottleneck.
Thanks and appreciate your help in this.
Regards
Ram
Thanks Ram

hi inderjeet,
The application has gone live and its on production, the same application is on pre-prod and UAT, system testing and integration environments.
The infopath form used to work very well on all these environments before we installed sharepoint 2010 sp2. but the moment we installed sharepoint 2010 sp2, the infopath forms have slowed down.
Microsoft has acknowledged that there is an issued with sharepoint 2010 sp2 and infopath form performance, but they are not able to provide an appropriate fix on this.
We have another environment where there is no sharepoint 2010 sp2 applied only sp1 is applied and the infopath form works very well within fraction of seconds.
So your point no. 1 and 2 and 3. does not reveal anything. Fiddler does not give any detailed component by component breakup where the time is taking more.
The form used to work very well before we applied sp2.
I want to know a tool that gives me exactly component by component grant chart kind of breakup of time taken when the infopath url is requested on the browser.
Thanks
ram
Thanks Ram

Very Slow Portal Forms Performance

My customer is running a simple (one table) 3.0.8 Portal Forms application on Solaris. The forms are created in .19 seconds, but take 7 to 10 seconds to display (even when just leafing through results). Direct queries on the table are very quick, and Portal Reports on the same system are fine.
I have determined that there are no Forms related traces in the log file.
Suggestions?
Thanks, Wendel Yale

Wendel,
Please take a look at the following post, I posted the workaround information there:
http://technet.oracle.com:89/ubb/Forum81/HTML/000395.html
It's a bug in 3.0.8 fresh install only, basicaly it comes down to 2 missing indexes.
Thanks,
Dmitry

Portal slowing down after import of application (New bug in 3.0.8 ??!!!!)

We have two complete IAS installation (Portal 3.0.8+DB 8.1.7.0 EE) based on NT4.0. One is development, second production. Before moving application, clean prod machine is running forms very fast (least than 1 sec to show complete form). After importing application into the same schema (moved exp/imp db utility), performance is slowing down 1000%. The same form appear in 3~4 minutes.
What's wrong with my portal.
Does anybody move successfully from dev to prod on NT environment?
I'll appreciate for any comments.
Marcin

Regarding the performance issue..
There is a workaround provided at: Thanks for this - helped 100%
Marcin
PS.
Now I complete give up. We bought IAS1.0.2, which appear rather like beta version (more 20 registered bugs found just by us). Than oracle support concern that ver. 3.0.8 of Portal will be cure for any previous bugs. Then I lost two weeks of my work trying to install new version and fighting with low performance.
Small piece of history:
Portal 3.0.8 for NT was available since 12 april 2001.
31 may 2001. Now Oracle is saying that 3.0.9 will be bug free. Maybe you should sit down for a while and develop some ver 3.x.x.x test and after you don't find anything release it.
Don't test your software on the customers.
We bought sw, get the knowledge and want to start our project. But how we couldn't do it on platform which is changing every three weeks?!!!!!!
It's smells like Microsoft.
NT4.0, srvpack1, srvpack2 (dangerous),srvpack3 forget,srvpack4, srvpack5 - Y2K, . . ... .. .

Slow down printing speed for Smart Forms

Hi,
Is there any command (etc.) to slow down the printing speed of an Hp laserjet when printing a smart forms?
I need that because when I print that smart form to fast I run into print out quality problems.
Many Thanks

hi,
take print out in a dot matrix printer instead of your laser printer without changing any settings.
Coz i tried this once, i was successfull. But, the printout will be very slow.
regards,
kool.
