Problem with DVT components on headless server

JDEV/ADF VERSION: 11.1.1.0.1
TECHNOLOGY: Fusion Web Application, WLS 10.3
Hi,
maybe someone has/has the same problem. I have created a page with
some basic dvt components like pie and bar charts. Everything works fine on my dev machine.
When I deploy the generated EAR on the test env (OEL 5, headless) and try to access the
page (which contains the dvt components) I get the following exception:
"Can't connect to x11 server ...."
and the WLS shuts down!!!!
Has anyone an idea if an x server is mandatory?
Thanks in advance for any hints,
Andreas.

Andreas,
I don't have a Linux box to test with at the moment, but it has been a common thing I've dealt with in other environments. Have you tried setting up a VNC server on the Linux box and setting the DISPLAY environment variable to reference that display before starting WLS?

Problems with Logical Components

Hi All,
I am having problems with Logical Components with our project. We are implemeents SAP HCM and we have defined a logical component Z_ERP for the ECC server. now when you look at the transaction from SOLAR02 it seems they also have a logical Component SAP Learning Solution that is assigned to them. what could be the cause of this???

Hi Trevor,
If you brought them in from the Business Process Repository, the logical component is going to be the default one. If you want to use your own, you need to replace the default one with yours.
You can do this in SOLAR_PROJECT_ADMIN by going to the System Landscape tab > Systems tab > highlight the SAP Learning Solution logical component row > press F4 > replace it with Z_ERP.
If for some reason SAP Learning Solution isn't listed as a logical component you may have to add it, you can also just go to SOLAR02 > Edit > Replace Log. Comp > Enter SAP Learning Solution in the top box and Z_ERP in the bottom one > click Save.
regards,
Jason

Problem with shares on Windows 2003R2 server from a Windows 8.1 PC

I'm having problem with shares on Windows 2003R2 server from a Windows 8.1 PC. It times out when I try to copy a file from my PC to the server and I get an error message saying "There is a problem accessing network drive W:\. Make sure you are
connected to the network and try again."
I have no problem copying files from the server to the PC.
Any ideas?

Hi,
How about your problem now? Have you test other machine also installed Windows 8.1? Did they have this problem?
To diagnose this problem, firstly, please check Windows 2003R2 firewall settings, also can disable firewall temporarilly for test.
Secondly, try to use Network Monitor to capture network communication package for test.

Problems with I/O on Unix Server

HAllo
I have a Problem with reading/writing on the Server my Tomcat is running.
My Application does not find the properties file allthough i tried to get my path with System.getProperty("user.dir"), and also tried to set an absolute path too.
It is also not able to create a new file.
My Question: What rights do applications running in tomcat have by dafault?
How cat i change this rights?
And how do the path have to look in my code if i want to set it fix?
I tried thid ones:
"/mydir/myfile.txt"
"\\mydir\\myfile.txt"

Tomcat is a regular application that has the same rights as the user executing it. Does Tomcat run as a user who has access to the directory you are trying to read/write from?

Strange problem with SQLPLUS when client and server on the same box

Hi,
I have the problem with SQLPLUS when clinet and server on the same machine.
With client and server on the same machine i am running the command
sqlplus -l username/password@connect_identifier as SYSDBA.
With this command, even if you pass in wrong username or wrong password or both as wrong you can able to connect to database and execute queries.
Once Connect_identifier is correct and trying to log in as SYSDBA ,sqlplus will log in to DB with any username and password.
How to get rid of this behaviour. Is there any way to do this.
I am running this command by creating a process in C#

Thanks for the info.
How does Oracle/SQLPLUS allows any username or password to log in to DB with SYSDBA Privillages? What is the concept behind this.?
This is explainted in the above mentioned link:
Operating system authentication takes precedence over password file authentication. If you meet the requirements for operating system authentication, then even if you use a password file, you will be authenticated by operating system authentication.

Problem with the% deviation from Project Server 2010 field

hello
I have a problem with the% deviation from Project Server 2010 field.
Within a file or project, this project contains tasks.
Each task has completed the field% deviation.
Within the row "Summary" in the field of% deviation does not perform the sum of all fields of tasks.
Only occurs on certain projects, these projects have the view of PR Progress Report
Anyone know happens?
thank you very much

Hi
Sorry, I'll be more specific now.
Within the field% deviation. Your settings in PWA is:
The formula for field% Deviation:
Str (IIf ([Job baseline] = 0; IIf ([Working] = 0, 0, 100); IIf ([Working] = 0; -100; Int (100 * ([Job] - [Work Online base]) / [Working baseline])))) + "%"
Under the heading rows Calculation Summary:
> Use formula.
Within the field Allocation Calculation of rows:
> It is labeled the "Apply unless you manually specify".
The field [Job] and field [Job baseline] are fields Pack project server.
The error is in project, in the list of tasks.
In the top row, this row summary makes the sum of the ranks of the tasks of the file.
But in my case only in the summary field the same value appears in the tasks.
In all the cells in column% deviation appears the same value.
I hope it helps.
thank you very much

Problem with inbuilt Solaris Apache Web Server v 2.0.58

Hi,
Set-up:
We are working on a custom application which works with the inbuilt Apache Web Server on the Sun Solaris platform. Here are the details of the versions of the various components involved:
Apache Web Server: Version 2.0.58
Platform: SunOS 5.10 Generic_127111-03
Our application is in the form of a shared library(.so binary) which is loaded into the Apache Web Server by mentioning the following directive in the Apache Web Server's configuration file (httpd.conf).
LoadModule at_module "/var/apache2/logs/sample/sample.so"
where, sample.so is our application's binary
and at_module is the name of the module.
httpd.conf file has been attached for your reference.
Attachments:
httpd.conf - Apache Web Server's configuration file.
sample-apache.cpp - Sample program which is showing the problem.
httpd.h - Apache Software Foundation's file which contains the structure "request_rec" that represents the current request.
Problem summary:
For each request to the Apache Web server, the server maintains a table of type "apr_table_t" which contains the header environment from the request. There is a structure "request_rec" maintained in the httpd.h file:
/** A structure that represents the current request */
struct request_rec {
/** The pool associated with the request */
apr_pool_t *pool;
/** Request method (eg. GET, HEAD, POST, etc.) */
const char *method;
/** MIME header environment from the request */
apr_table_t *headers_in;
In our case, when we try to retrieve the address of "headers_in", we get a NULL Value. Please refer to the attached "sample-apache.cpp" program. In this program, inside the access_checker() method, we try to retrieve the address of "headers_in" and get that as NULL:
extern "C" int access_checker(request_rec *r)
     FILE * fp;
     fp = fopen("/var/apache2/logs/sample.txt", "a");
     fprintf(fp, "\n r->headers_in = %u, r->method = %s", r->headers_in, r->method);
     fclose(fp);
     return OK;
Here is the output of the sample program after accessing the main page of the Web server:
r->headers_in = 0, r->method = GET
r->headers_in = 0, r->method = GET
r->headers_in = 0, r->method = GET
Though we are able to retrieve one member of the structure request_rec (method), we are not able to retrieve the address of the other member (headers_in).
Observation:
We made an interesting observation that when we used the same sample program with the inbuilt Apache 2.0.52 Web Server on Solaris, we were able to successfully retrieve the address of headers_in. Here are the details of the set-up which is working fine:
Apache Web Server: Version 2.0.52
Platform : SunOS 5.10 Generic_118822-30
Thus, there is something different which has happened between the Sun's Solaris Apache Web Server's versions 2.0.52 and 2.0.58 which is making it unable to retrieve the address of the request headers (headers_in).
I am requesting someone to kindly shed light on this difference and let us know if we need to change the way of retrieving the request headers for Solaris Apache 2.0.58.
Thanks,
Atul.

The only way you can achieve it is by running the web server to listen on port 80
Please change the port in your httpd.conf file for the webserver and restart it.
If any other processes are running/using on port 80 on that machine, then please stop them, otherwise you will not be able to achieve your requirement.

Problem with provisioning and external SQL server connection

I am configuring IPAM 2012 R2 on a our management server. Completed the first step by enabling the feature. No issues.
Now I am on the Provisioning IPAM step. I get to the Configure Database step...
I choose Microsoft SQL server,
What should those values be in the Server name and Database name fields. Instructions show fqdn or ip address but that doesnt seem to be working for me.
I get the following error at the end of the Provisioning IPAM wizard,
IPAM Deployment failed with the following error.
Failed to connect to database server. Check the database name, connectivity and remote access.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.
(provider: TCP Provider, error: 0 - No connection could be made because the target machine actively refused it.)
You can restart this provisioning wizard from the IPAM overview page.
From the management server I have tested the SQL Connection with a udl file. I used myServer\myInstance and it works. It reports that I have made the Connection to the server and database with the sql credentials i have provided.
Thanks

Ran
into a problem with connecting to the DB on the SQL server from the IPAM server. The Dba and I checked the target SQL instance was enabled TCP and listening on a valid TCP port. SQL server was set to use port 1443 for incoming connections.
IPAM was set by default to use 1433.
Also used
netstat-n to identify issue and verified 1443 on SQL server was
being used. Made the correction under the IPAM provisioning wizard and connected to the database. Fixed.
Important note I was able to connect to the database with a .udlfile
without any issues
Also note that 2012 R2 IPAM only supports 2012 SQL Enterprise. Why?

Problem with scanning - printer display shows "Server connection error"

My printer has been working great and I have had no problems with scanning. But two days ago, all of a succen I rec'd message "server connection error". I tried to send to email as well as computer. Got the same message. As usual, I don't recall any action on my part that could have caused this problem. The copying and printing functions work fine. Detailed advice to someone technically challenged will be much appreciated. Thank you.

Problem with yahoo! SMTP POP server mail account on new upgraded iphone 4.3.5

PLEASE HELP!
I am a California AT&T wireless customer with a new iphone 4 on the iOS 4.3.5 upgraded system and suddenly I am unable to successfully add my Yahoo! email account and have it configured to send/receive my emails. I was able to successfully add my gmail and Microsoft exchange server account, but only problems with the Yahoo! I checked all the settings, have done several add/delete accounts, restore network settings, and retry/reboots, to no avail. This is a seriously annoying problem, it worked with the pre-upgraded older version fine without any problems ever. I continually get the same error message: SERVER UNAVAILABLE, please try again later.
I know this error is inaccurate because all my other email accounts work fine as well as Safari and all other internet connections and apps. It is not a phone thing, it is some yahoo and upgraded software incompatibility issue that no one seems to have resolved yet.
This is a SMTP PUSH POP account, and I have literally tried everything. I have tried all the fixes while connected to wifi, and then tried them just via my 3G cell network connection. I read on a message board about turning on/off SSL, could someone tell me how to do that? When I go into to:
settings>mail accounts>outgoing mail server SMTP>Yahoo! SMTP, everything is grayed out and I can't change any ports or SSL.
When I try to manually add a server, which I was told was a fix, I don't know what to type into the host name. Does anyone know how to help?
I have seen this problems on numerous message boards, even in the UK. I contacted Apple Support, with no success in resolving this problem, had an open case for several days contacted several supervisor personnel, all advised me to contact Yahoo! who do not offer customer care via telephone only online, and nothing there helped to resolve my issue.
PLEASE, PLEASE HELP!
THANKS

Yahoo's servers have been having problems off and on now for close to a month if not longer. There's not much you can do about it except talk to Yahoo, which is kind of like beating your head against a wall. They've had problems like this off and on since as far back as the mid 90's. I gave up on them long ago. Just convert to something else and dump them. It's not worth the headache.

Problems with many components

Hi everybody, I am building a GUI using swing, everything is ok, but some times the OutOfMemoryError() occurs. I have 256 Mb in my PC, but in my application I use a lot of components too.
Does any body know how can I manage the memory and free the space that is not in use????
Thanks in advance.

Hi!
I've the same problem with some of my applications. What I do is to set the max heap for the java virtual machine. I work with jdk 1.1.8, and the line command parameters are:
java -ms14m -mx60m my_application
where -ms is the initial memory heap and -mx is the maximum memory heap. You can increase them if you continue having memory problems.
About freeing the memory, try searching in the forum for "garbage collection". There are some recomendations to do that.
Hope it helps!
Regards
