Dr.Watson problems solved.

DR.WATSON PROBLEMS SOLVED:
System:
WLS 5.1 with SP11 running on NT4 Using OCI817_8.
Oracle 7.3.4 running on NT4.
Problems:
Dr.Watson exceptions in native code...
# An EXCEPTION_ACCESS_VIOLATION exception has been detected in native code outside
the VM.
# Program counter=0x60239689
When asking BEA and Oracle:
"Use the latest OCI available. It is backward compatible !"
What have been done to solve the problem:
Going through all SQL code (and doing some rewriting), configuring connection
pools (TestOnReserve / TestOnRelease, refresh, etc) and several other configurations...
At last, we tried to change to the OCI version matching the Oracla versions we
were connecting to (from OCI817_8 to OCI734_7).
Voila ! NO MORE DR.WATSON EXCEPTIONS !
Our conclusion:
If possible, use the OCI version that matches the Oracle version you are running
on.

Hi Abhijit
Couple of pointers which could resolve the issue:
1. Since you are using the JDBC-ODBC bridge what occurs internally is that your JDBC API through the Virtual Machine make calls into the ODBC API on your Windows system. So the Watson error that you are getting is probably an illegal access by one of the methods in the ODBC API - this is for the Diagnosis part.
2. The Solution part -
a. Should I change my JDBC-ODBC driver? Not necessarily because the problems could be with the ODBC interface implementation and changing the driver might not help.
b. Should I change my programming style? This is one thing which could really help. The problem with creating connections each time is that it takes a lot of resources to do it, So there is a performance degradation. What you could do inyour code is use a Java Bean to create the required Connection. You can also think of using a prepared statement appropriately encapsulate it since you are invoking a particular query repeatedly. In your JSP page you can retrive(create) this bean through the jsp:useBean tag with the session as the scope attribute. The <jsp:setProperty methods could also be used to set the DSN name and the driver.
Once this bean is successfully created you have an open connection.
Now for the part you have pasted - replace the create connections with getting a new Statement object which would hold your Query. At the end of the JSP just close the Statement object.
Once you are done updating the page you may transfer the control to a different JSP - Let that transfer trigger the connection close in the Java bean.
This should solve the Dr.Watson problem.
Good Luck!

How to problem solve adf issue in the mx340 model

how to problem solve adf issue in the mx340 model

Alex,
the missing thing in your example is the fact, that if only one value is selected, the parameter has exact this value like BOSTON. If you choose more than one value, the parameter includes the *'*, so that it looks like *'BOSTON','NEW YORK'*. So you need to check in the package, if there's a *,* in the parameter or not. If yes there's more than one value, if not it's only one value or it's null.
So change your package to (you need to expand your variables)
create or replace package bip_departments_2_parameters
as
p_dep_2_param varchar2(1000);
p_loc_1_param varchar2(1000);
p_where_clause varchar2(1000);
function beforereporttrigger
return boolean;
end bip_departments_2_parameters;
create or replace package body bip_departments_2_parameters
as
function beforereporttrigger
return boolean
is
l_return boolean := true;
begin
p_where_clause := ' ';
if p_dep_2_param is not null then
if instr(p_dep_2_param,',')>0 then
p_where_clause := 'WHERE DNAME in ('||p_dep_2_param||')';
else
p_where_clause := 'WHERE DNAME = '''||p_dep_2_param||'''';
end if;
if p_loc_1_param is not null then
if instr(p_loc_1_param,',')>0 then
p_where_clause := p_where_clause || ' AND LOC IN ('||p_loc_1_param||')';
else
p_where_clause := p_where_clause || ' AND LOC = '''||p_loc_1_param||'''';

WiFi connection problem solved

My intel iMac and MBA had no problem but iPods 3g and 5g did. I had an old Netgear router connected and sitting next to my Airport Express. On a hunch I diconnected the Netgear and created a guest network to replace the one on the Netgear. PROBLEM SOLVED!
Evidently our iPods and boarder's iPhone had problems sorting out the signals and finding the right addresses. Moving the AE to a higher and slightly more central position also helped.

Same here on a Vodafone PocketWiFi 2.
Tried NetworkManager, wicd, wifi-menu but all have the same issue.
I recently installed Aptosid on another machine and it has the same problem... It also has kernel version 3.9.
All the live CDs I've tried work, even an Arch CD from May works, though a current install does not.
I have no problems connecting to another (wpa2 enterprise) network yet can't on this 3G modem.
I'm hoping this isn't a permanent issue and perhaps an update very soon will fix this.
It seems the only way to fix this for now is to use an old version of Linux. I'm currently running a virtual machine only for the purpose of Internet sharing, very annoying.

Bug fix for Mac book wireless - problem solved!

Aparantly there is a rather large number of folks out there who've discovered this dillema with wireless not working very well at this point on the Macbook.
Well, I can attest there is one very good solution out there for this issue. This application called Sonar Theater from www.sunray.tv includes a bug fix for the wireless connection issues with Macbook in their latest 1.5 release of Sonar Theater.
I downloaded it, put it into my start up folder and waalaa! problem solved. I've haven't any more issues with dropped wireless since - it's been running constantly for over 2 weeks now.
I haven't even attempted to touch my router configuration - don't need to.

Welcome to the better life of Macs. I am using Sonar Theater too and it's been working very well for me. In fact, I'm getting hooked on just texting a message to my Mac book to fire up user sessions now. I think if you give the Mac Book some time however, you'll find that there really is no comparison to PC's. Your life overall is going to just keep getting better as you dig in to the resources available to new Mac users.
I'm sure it seems confusing to PC users at first, but here's how to set up any application as part of your startup sequence. It really is extremely easy and simple compared to the PC world. Oh and by the way, in reality, Mac users refer to this as your login sequence. So, at login time, you can do a multitude of different things for each user account you might want to set up. Naturally, you can choose to share or not share applications and data between these user accounts on your Mac too....
Mac OS X 10.3 or later
1. Log in as the user who wishes to have a login item or as an admin user.
2. Choose System Preferences from the Apple menu.
3. Choose Accounts from the View menu.
4. Click the name of the user.
5. Click the Startup Items button
6. Click the "Add {+}" button.
The item you selected will automatically open the next time you log in.
there are several ways to get good info from the apple community on tips and tricks as well. you should just try the apple os x web site...here,

happy mac-ing!

Mediawiki, mysql, php? problems [SOLVED]

On Sunday my Arch install that is hosted by Slicehost became unresponsive to them so they had to do an emergency reboot. After it came back up my install of mediawiki was (and still is) only returning a blank page (at least in Firefox). After some digging I found out that part of the problem was that mysqld wasn't starting so I managed to get that fixed by commenting out the lines relating to innodb and putting in skip-innodb into my.cnf. But I'm still getting a blank page.
According to Mediawiki's manual, "A blank white page indicates a PHP error which isn't being printed to the screen." They give two lines to put into LocalSettings.php to force error messages but after doing that I'm still getting a blank page. Changing display_errors in php.ini to ON didn't have any effect. When I load the wiki in Safari I get the following error: "Got java.io.EOFException (Server closed connection while sending the HTTP header.): http://some_url.com/mediawiki/index.php/Main_Page". I have no idea what this error means and googling java.io.EOFException doesn't bring up anything very helpful. My PHP Test Page indicates that PHP is up and running.
Any ideas on fixes or where I can find more clues?
[EDIT]
Mysql was definitely the root of the problems with Mediawiki. I tried nearly every suggestion listed in the forums for fixing a mysql install that wouldn't start but nothing worked. I even completely uninstalled mysql and reinstalled it but it still refused to start. I switched over to postgresql and switched mediawiki to run with that. Problem solved.

There are some other things that must be done to connect to
the database
(such as passing the usernamee, password, and host info to
mysql_connect()
and storing the connection resource), and those might be in
the include
files. I generally place all of the connection parameters in
a separate file
that is located in a folder that can't be accessed by a
browser, for
security purposes.

Acrobat printing problems (solved)

Hi Folk
I'm getting on well with Arch apart from one problem, I can not print from Acrobat reader, it accepts the command and does precisely nothing, the jobs are appearing in cups but not being printed, I can print from Open Office and test print from cups but no cooperation with acrobat, anyone have any ideas? thanks
Pete
Last edited by pete051 (2009-09-29 19:14:12)

I don't know what DE are you using. In my case, I use xfce and when acroread starts with his stupidity I just change the print command to 'xfprint'. That forces acroread to redirect the print job to xfce's printing frontend, and problem solved.
Now, if you're using kde, I guess there is something named 'kdeprint', 'kprint' or similar. For gnome, I've no idea.
I hope this helps.
p.s. Sometimes, cups takes his time to print. When its taking too long I purge cups' temp files and restart the daemon.

Stuck with grub problem (SOLVED)

Today i tried to upgrade my Arch Linux, it downloaded everything that should be downloaded, it was installing upgrades but at the installing grub it stucks as like this
"Copying /boot/grub/grub.cfg.pacsave to /boot/grub/grub.cfg"
I've waited it for about 15 minutes, it didn't move on. So i did ctrl+z to break. Then i tried to update again. But it gives an error which is:
error: failed to commit transaction (conflicting files)

Error occured, no packages were upgraded.
Please help me guys!

Am I able to find my iTunes serial number? I need it for the problem solving as my problem is solely bad on my iTunes.

For the Apple problem solving section I need a serial number, my issue is that my problem regards missing contents within my iTunes. Do I have an iTunes serial number? And if so, where can I locate it? If there is not a serial number for iTunes, advice on what to do next is much appreciated.

iTunes has no serial number. If you are trying to get to Apple phone support, that is linked to the purchase of Apple hardware, so you need to enter in the serial number of an Apple device. Otherwise, for assistance with problems with iTunes itself you would need to call Apple Support and they would almost certainly charge for the call. I would instead suggest you post the issue you're trying to address here in detail. Someone here can probably offer suggestions.
If your issue is with the iTunes Store, not the iTunes application, go here:
http://www.apple.com/support/itunes/contact/
and follow the instructions to report your issue to the iTunes Store.

HOTSYNC PROBLEM SOLVED -between Palm TX using desktop version 6.2 & Windows 7 64 bit

I to struggled with performing hotsynch between my Palm TX and my new Windows 7 64 bit computer. After 2.5 hours of palm tech support on my pc they gave up and deemed the task not solvable. I spent hours trying various options-nothing worked until this.
I performed a google search for Toshiba bluetooth x64 drivers. This took me to the following link:
http://aps2.toshiba-tro.de/Bluetooth/?page=download
I downloaded PC Bluetooth Stack version 7.00.10 for Windows 7 x 64. After downloading this suddenly the palm syncing software on my pc gave me the option to connect via bluetooth and I was on my way. My bluetooth dongle (cirago BTA-3210) was not a toshiba, but did use the toshiba driver stack. The driver that came with the bluetooth was not up to date- even though it was just purchased at newegg. The driver update that my pc found was also not 64 bit compatible. The only fix was to download the driver from Europe- hooray!!!!! PROBLEM SOLVED

PROBLEM SOLVED--CS5 WIN7 X64 INSTALL ERROR DEPENDENCY FAILURE

PROBLEM SOLVED!!!!!!!!!!!!
I just spent 9 hours straight on this, but will was stronger than "its". Now I have both cs4 and cs5, but hopefully it will work if you just have cs5 as well. I also did not try runnning cs5 installer first after implementing the fix, maybe that will work too..And when getting the cs5 error, I went to re-install cs4 but got an error as well so that is why I took the steps I did. On 7x64 do the followin
First run the cs5 cleanup tool and reboot.
Second, go into c:\program file(x86)\common files\adobe\installers . Delete everything in it
Then go into you registry (start, run, then type regedit) and expand to this registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\ Components ...(if this isnt there, try an install again, then go to the folder that you deleted the files from a moment ago and extract the log from the zip file and open it and go to the end. where it says error 1402 will be followed by a unknown\components\(a bunch of numebers right here)\(more numbers) ...
Copy the numbers directly after the components\ and go back into registry and click edit then "find" paste those numbers into the box and hit find..when you get to the key, scroll ALL the way back up to components again. Right click components and hit permissions.. Go to advanced and then the ownership tab up top.. click edit, hightlight administrator(s), check the box to "replace subcontainers" and click apply. respond yes to everything and close that and hit apply again if asked. then click the add button above the advanced button you just clicked. when the new box appears, click advanced and then click find now. Highlight Administrators and SYSTEM and hit OK. Then give both of them full rights and hit apply. Then click advanced again and in the first window check the box that says "replace all child objects...." and hit apply. accept the prompts and hit okay.
Now go into c:\windows and on the system32 folder, right click and go to properties. Go to the security tab. Click advanced and then "owner" and click edit. highlght administrators and check the box "replace all child object....." again and hit apply....
Now give Administrators, SYSTEM, AND TrustedInstaller full rights by clicking edit above the advanced tab in the first properties box.. Then click advanced again and in the first window click replace all child object....." again and hit apply....
Now do the same for the winsxs folder and (for good measure i did syswow64 but not sure if its necessary)...
Now you should be able to install both versions..(as i said, I installed cs4 first, maybe it was not necessary)...
If you dont like the idea of just blindly giving administrators full rights to all system folders, you can spend MANY MANY hours running the installs over and over and getting the faulty registry value that caused it to fail and create specific permissions for that and then go on to the next value that fails......what a pain

Thank you for this.
I have been trying to install CS5 MC now for weeks. I first got it to install everything except After Effects and Premiere Pro. Then trying to follow all the suggestions on this forum I wound up not being able to install any part of it at all. Now..
Well...following your kind suggestions as much to the letter as I could I have now been able to install everything...except Affter Effects and Premiere Pro. Sigh.
At least I can get back to work on everything that doesn't require AE and PPro. I still need to get them installed and working.

Problem solving expertise appreciated. What does a MacPro do in its initial booting phase?

My MacPro 3.1 (2008) with 20 Gb Ram does no longer want to boot. I checked the harddrive (startup disc), it is OK (my MacBook) boots from it. I checked the ram, it appears to be OK. When I push the power button the fan begins to work, red lights appear shortly on the RAM circuit boards and they go out again but then nothing happens. Monitor does not wake up, there is no start up chime, machine appear unresposive to any keyboard commands.
Anyone can tell what may be wrong, what the cause is why the MacPro does no longer want to boot and what could possibly be done about it?
So some Problem solving expertise and advice is higlhly appreciated. I really like to know what exactly does a MacPro do in its initial booting phase? Information that could bring life b to my well respected grand-old lady.

Conventional wisdom is that you get nowhere until you get the chime.
For that reason, the approved method is to remove everything that could possible be dragging down power and test the absolute minimum configuration, hoping to get the chime. Once it chimes, you slowly build it back up. adding one part at a time until you find something faulty or it "comes clean".
Disconnect AC power and remove:
graphics card
All other PCIe cards
All Hard drives
All Optical drives
All RAM -- then check for the power light blinking
next step is to restore one pair of DIMMs and try for the chime.
Then more DIMMs
Then graphics card, etc.

Everyones Oracle Linux Problem solved!!!

Everyones Oracle Linux Problem solved!!!
Here's something Linux people should relate to: Use what works!
what works?
NT works! NT works great with 8i AND OAS.
No hassles at all!
Up and running within one day!!!!
Guaranteed!
U don't see a NT forum here with people having ridiculous install problems like Linux people?
Perhaps Oracle should moderate this newsgroup and even give an authorative answer or two?
null

I have switched our development and soon production databases to Linux because it runs like a charm. Fast and efficient, no problems. The installer has been a problem no doubt because Oracle put less of an emphasis on debugging their Linux installer than their idiot-proof NT installer.
By the way, I was able to circumvent installer problems by just linking svrmgrl to svrmgrlO; this avoided the dreaded segmentation fault and kicked everything open just fine.
BTW, about NT; what makes an OS is not how well everything works when everything is going well, but how bad it gets when something goes bad. For instance, the segmentation faults on Linux weren't a problem because I just picked up and continued; on NT you'd have to restart the whole system...not a pleasant feature.
