How to use HR application with Remote Database ?
Hi,
I tested the HR application but it working on local database.
How can I create same application which will communicate with Remote Database.
Any guideline ?
Regards,
Ajay SharmaHi,
Thanks for the reply.
My scenario is that there is one web service and this web service has one method name "getQueryOutput".
Input parameter to this method is Select query
select ename form empthe return type of this method is Document. Currently I hard coded the select statement as I want to display all employee name as application starts.
But I am getting following error

ptypes.add(String.class);
params.add("select ename from emp");

Session "" failed to start with the following error: 0xc0000022
Newly installed Windows 2012 R2 server throws the following event roughly every 3 minutes:
Session "" failed to start with the following error: 0xc0000022
The PID referenced in the event points to WmiPrvSE.exe running as NETWORK SERVICE. Is there something obvious I'm missing because I'm not sure where to go with the information I found so far. I already did my fair sharing of Binggling and everything
I find doesn't apply or doesn't fix the problem.Hi,
Can you let me know the full event log content?
I suggest you restart the Windows Management Instrumentation service.

AlbertoHi,
IP Helper (service name 'iphlpsvc') is apparently designed to improve a Windows PC's support for IPv6 network protocol.
I suggest you try enable the dump collection by copying following words into notepad, saving it as dump.reg and importing it:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\localdumps\iphelper.exe]
"DumpFolder"=hex(2):63,00,3a,00,5c,00,63,00,72,00,61,00,73,00,68,00,64,00,75,\

Session "UpdateUx" failed to start with the following error: 0xC0000022
Running WTP Build 10049 and get the following error, after every boot/reboot :

Expanding this, by clicking on it, produces the following message :
Session "UpdateUx" failed to start with the following error: 0xC0000022
Any suggestions for a cure.Hi athol49,
Which account you have used to logon this machine?
This error code is mostly related with the service permission, which indicates that the permission is not configured correctly.
Try to boot into safe mode and check this issue again, make sure there is no 3rd-party software involved.
Next thing is to create another admin account( or enable the built-in admin account to create a new admin account, as this one have permisssion issues), then check this issue again.
Further, run the DISm command to make sure there is no component issue:
DISM /Online
/Cleanup-Image
/RestoreHealth
/source:WIM:X:\sources\Install.wim:1
/LimitAccess
Where the X: is the drive for the install media, or the mounted ISO.

Does anyone know what this is or how to prevent it from
occurring?
I'm running Windows Server 2008 R2.
Thanks much,
JamesNot according to my computer - (actually its at least 4 years now) which among so many other errors have haunted me from the day I bought it and took it home. I've spent literally a year of time out of the 5 I've had this laptop which btw is a home computer,
not a small business pc - searching, trying fixes that didn't work, searching more trying fixes that worked only to have the same scenario begin again 2-3 months down the road OR new ones pop up - which starts the process all over again. I'm now getting BSOD's
about once every 2-3 days with no reason in the event viewer.
And I continue to work on all the errors, warnings and critical errors with no results. I just wish Microsoft would fix these issues instead of developing new OS's that not only carry these problems over but add new ones to each new OS. Don't misunderstand
me. I like Windows, in fact I'm one of the very few graphic artists out there that prefer it over a MAC but its quite disheartening to be continually working on these issues to say the least.
Of course, it's just my opinion....I could be wrong! -

Generally we can safely ignore the errors in the Event log. Aas we don't if you have get other issues in your computer, you can test your computer in the Clean Boot mode. This method will help us determine if this issue is caused by a loading program or service.
You can try the the following steps:
1. Click the Start Button type "msconfig" (without quotation marks) in the Start Search box, and then press Enter.
2. Click the "Services" tab, check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray).
3. Click the "Startup" tab, click "Disable All" and click "OK".
Then, restart the computer. When the "System Configuration Utility" window appears, please check the "Don't show this message or launch the System Configuration Utility when Windows starts" box and click OK.
Please test this issue in this Clean Boot environment, if the issue disappears in the Clean Boot environment, you can use the dichtomy to quickly narrow down which entry is causing the issue. You can refer to the
KB929135.
Good luck!

This is a very poor answer. This guy doesn't know what he's talking about because if you tell someone its ok to "safely ignore the errors in the event log" as a blanket instruction ESPECIALLY because as he stated so himself
he didn't know if there were other issues with the OP's pc then he's giving really bad advice. If you ignore errors in the event log then over time your system will degrade and you will have other issues.. Every error on your pc should NOT be ignored.
It should be decided on a case by case situation.
Furthermore this is an error involving the Windows Session which it states has failed. Definitely should NOT be ignored.
I've got the same error which has suddenly just showed up. No BSOD, Do not have WHS installed and all my media center connectors have NEVER been connected. I don't believe this is a service issue. I think it has something
to do with kernel event tracing.
Of course, it's just my opinion....I could be wrong! -
Cannot query tables in remote database
Hi, I have looked around for similar topics but have not found anything that would be close to my problem. I created a public link to a remote database from my portal database, it is a public link and I can query tables in the remote database just fine when I am on the sqlplus prompt. When I try to create a report, or a dynamic page, it lets me go through the wizard steps ok, however when I run it as a portlet or just run it as a report/page it does not seem to be able to see the query. Below is the response I get from running it as a portal. I am logged in as portal30.
ORA-01017: invalid username/password; logon denied
ORA-02063: preceding line from C2K (WWV-11230)

Please help, I have tried everything from public to private synonyms for the linked tables and it just does not work. I am using the most recent version of portal that came with ias 1.0.2.2.0Actually I solved my problem, it looks like I should have used the db link utility with the portal, I linked the databases on the sqlplus command line and it seems like that was the issue.

Multiple Error Messages, starting With 500 null Error
I've been experiencing multiple error messages with
ColdFusion 7.0 on Ubuntu Linux/Apache2 for the past several days,
starting with the 500 null error (see
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=f9e312a2),
which ocurred on only part of the site (a set of forms requiring
remote login). Now, the following errors are appearing on various
CF forms: "An I/O error while manipulating the sort index" and "An
exception occurred when setting up mail server parameters" and
finally, "No space left on device." All these errors are occurring
on add/edit forms and cffile upload forms that were working fine a
few hours ago and that haven't been changed.
Right now, I'm replacing the license.properties file to deal
with the 500 null error. My question is, has anyone else
experienced this smattering of other error messages in conjunction
with the 500 null error? Or fast on the heels of it? What's the
deal with the 500 null error, anyway? Has Adobe made any progress
with this issue?Okay, this is a followup to my previous post (
http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?catid=143&threadid=1165765&en terthread=y).
Replacing the license.properties file isn't sufficient in
addressing the 500 null error. We are running Ubuntu Linux. I
understand that I need to replace jvm 1.5 with jvm 1.4.2. I'm
honestly not sure how to detect on Linux which version of jvm is
running or how to make sure that version 1.4.2 is what is running
when we reinstall ColdFusion. If someone could help me with this,
I'd appreciate it. The 500 null error is eating my Web site like
the Langoliers. Even some static .cfm pages are failing now. -
"User names cannot start with a number" error while adding a user
Is it possible to use WL Portal 7.0 admin framework to manage users with all numeric
user id ?
I got an error "User names cannot start with a number" while trying to add users
with all numeric user ids. I am using "portalAppTools" web app provided with WL
7.0 out of the box.
What "out the box" functionality do I need to change to make this happen ? Thanks
ShahThe problem is that when we have user groups starting with a number, then the search
feature doesn't work for user groups (case # 466837 with BEA).
So, which brings me to the following question:
a. Should the search feature work?
b. What is the limitation? I mean, it is designed not to allow user groups starting
with a number. So, there must be a reason for this. So, if we change "disallowFirstCharDigit",
will it have any impacts on Portal?
As an aside, it seems somewhat strange that the Portals can start with a number!
Thanks in advance

Hierarchy/heirarchical queries/query start with connect
ok... I have seen many examples of using hierachical queries. All of the example has parent as null and children with 1 parent. I haven't seen any query that queries a child with multiple parents.
For example.
Table A:
Child--Parent
1--null
2--1
3--1
3--2
4--3
5--2
Select query:
Select child, level
from A
start with child = 3
connect by prior child = parent
Result
Child--Level
3--1
4--2
3--1
4--2
Notice that it display the child '3' twice. Its because it has 2 different parent.
My question is that, how do I make the query to display this iteration once?Hi, Sentinel,
I'd love to see a solution that simple, but I don't think it's possible.
Suppose you want to see child=2 and all it's descendants:
--<"begin sample data">
with a as (select 1 child, null parent from dual
union all select 2, 1 from dual
union all select 3, 1 from dual
union all select 3, 2 from dual
union all select 4, 3 from dual
union all select 5, 2 from dual
--<"cut here">
Select child, level
from (select child, min(parent) parent from a group by child)
start with child = 2
connect by prior child = parent;Produces this output:
CHILD LEVEL
2 1
5 2I believe OP wants to get this for the descendants of child=2:
CHILD LEVEL
2 1
5 2[b]
3 2
4 3So what happened to child=3? For child=3, MIN (parent) = 1, according to this query. That's true when the universe is the entire table, but we're only interested in child=2 and its descendants.

Oc4j starting with Oracle Database & oc4j App Server on same machine
Hi ALL, can anybody help me(pls read this)
This is Sagar, i have created a GIS Application(java) using Oracle 10g.
Senario I:
oc4j server and oracle 10g Database Server on different machines:
When i start oc4j server with NO. OF Mappers = 64 or 30 in DNS using
1. oc4j -start (normally)
from the path c:/oc4j/bin by setting ORACLE_HOME path normally
application is working fine but when users are increased say 4 to 5 oc4j server gives error:
java.lang.OutOfMemoryError: Java Heap Space
I searched for this error i found a solution for starting oc4j as follows:
2.Java -Xmx1024m -Xms1024m -jar oc4j.jar
from the path c:/oc4j/j2ee/home --- oc4j.jar
Then map & application works fine and fast since heap space is increased to 1GB (speed is noticable)
but if...(in other senario)
Senario II:
oc4j server and oracle 10g Database Server on same machine:
if step 2: is used form above senario, oc4j Server does not gets started only it gets initialized...(server does not gets started)
but Step 1: is used application works fine but again heap space error as mentioned above is seen.
Again if changes are made in oc4j.cmd file in c:/oc4j/bin ....by giving the heap space command oc4j works fine but the application(performance) is very very slow but heap space error is not seen.
Please can any body suggest the solution.. application should work fast and also the heap space should be increased but taking the senario - oc4j App Server & Oracle 10g Database Server on Same machine..Hello,
How much RAM do you have on the machine? What is the size of the SGA for the database you are using?
if step 2: is used form above senario, oc4j Server does not gets started only it gets >initialized...(server does not gets started)What do you mean by this? Provide the output from the server when you start your server.
