Java network problem within 10g

Hello readers,
I have a rather hard to trace problem which is keeping me up several days now.
We want to implement a package for querying devices via SNMP in our database. There are no packages shipped with Oracle that come handy. UTL_TCP does not work because SNMP works via UDP. After all we came up with the idea to use http://www.snmp4j.org/. Locally on my development machine and on the command line of the Oracle database our first prototype of the SNMP query function works very well, but inserted into the database all I'm getting is a "Request timed out". Firewall mechanisms can not be the problem because the java code runs smoothly on the command line and also a snmpwalk on the command line suceeds, so the database is not blocked by any firewall. First I thought some permission via Java are missing, but I took a look in the USER_JAVA_POLICY view and worked this with SYSDBA out. A java application in Oracle connection via TCP to port 80 and fetching a website works allright, the thing not working seems to be UDP. Does anyone of you have any hints on how to debug, trace such a problem?
Greets, Yves

Hi,

no, this assumption is not necessarily true a firewall can block a program but not another one ...
ok, but at least your Java cod is runing well if not blocked.

Yes but, are you sure that the user who is runing the Java class has the same right as this application?
(i'm not sure but i think for this kind of permissions the user has to reconnect itself to the DB)
If i were you i woul try to grant more permisions to this user (not only giving execution rights but cheking with the networks rights)
have you tried to redirect the output when you call your Java class?:
SET SERVEROUTPUT ON
CALL dbms_java.set_output(2000);have you tried to see the network grants of the user?

Java Mail Problems within JSP Page

Hi all,
I'm encountering the following problem. I hava a jsp file named common.jsp with holds all common functions like write header and footer and also a send mail function. i include this page in all my other jsp pages. In the signup page - i need to send out 2 emails, one to the administrator and the other to the user who signed up. so i call that send mail function twice. the first call works(meaning it sends out the email) but the second call gives me a No SMTP Provider exception. Can anyone help me with this.
thx a bunch
p.s: i have included the sendEmail Function below
public void sendEmail(String emailServer, String sEmail, String sName, String rEmail,
     String subject, String strmsg) throws Exception {
     java.util.Properties props = new java.util.Properties();
     props.put("mail.host", emailServer);
     javax.mail.Session mailConn = javax.mail.Session.getInstance(props, null);
     javax.mail.Message msg = new javax.mail.internet.MimeMessage(mailConn);
     javax.mail.Address sender = new javax.mail.internet.InternetAddress(sEmail, sName);
     javax.mail.Address receiver = new javax.mail.internet.InternetAddress(rEmail);
     msg.setContent(strmsg,"text/html");
     msg.setFrom(sender);
     msg.setRecipient(javax.mail.Message.RecipientType.TO, receiver);
     msg.setSubject(subject);
     javax.mail.Transport.send(msg);
}

This is what i use and it works just fine

Problem with Java 5 and Oracle 10g JDBC driver

Hi All,
Currently we upgrade our web application to Java 5 and Oracle 10.2 JDBC driver. And we encountered a bug, when the user entered the information through UI and data didn't store into database (Oracle 9i). The problem is that this bug is not happend so often maybe once a day and this did not happen before we upgraded to Java 5 and Oracle 10.2 JDBC driver. Does anyone encounter the same problem ? Is this Java 5 problem or Oracle JDBC driver problem ?
Thanks,

sounds like a database problem...
Are you using a driver version that's supported for your database engine?
What else did you change? We once ran into a major bug in our application that had for 5 years been masked by performance problems in our hardware and infrastructure.
Once those were resolved the bug showed itself and caused tens of thousands of records to be erroneously inserted into our database every day.
It's certainly NOT a problem with your JVM (if it's a decent one, like the Sun implementation).
So it's either your database, your driver, your network (dropping packets???), or your application.
The upgrade may just have exposed something that was already there.

Screen Sharing/network problem seems confined to 1 volume. What's the fix?

I am having a networking problem on one of the volumes of my multi-volumed, three-Mac local area network, and I need a networking guru to identify the specific software file(s), application(s), or system configuration that is the cause of the problem. I have already spent several hours checking and re-checking the various hardware and system preference settings involved, and I have narrowed the problem down to a software corruption issue and/or system configuration issue on one volume.
I now need someone to identify specifically what the nature of the problem is, and how to eliminate it. I am not looking for a sledgehammer solution that says I should re-install all of the Mac OS X software on the problem volume. That may be held in reserve as a last resort. I'm looking for a more elegant approach, one that points out the specific corrupt files to remove without disturbing everything else.
Here's some background to set the context. I have a MacBook Pro laptop; a PowerMac iMac G5; and a PowerMac G4 hooked up in a network. All are running Leopard 10.5.8. All have file sharing and screen sharing enabled. Besides being able to connect to each other using registered users, my goal here is for each of the Macs to be able to share the screen of the others upon my demand. Since each of the 3 Macs can theoretically share the screens of the other 2, that makes a total of six possible connections. Five succeed; one does not. That's the problem. I am trying to determine why the iMac G5 cannot share the screen of the MacBook Pro.
The iMac G5 has no problem sharing the screen of the PowerMac G4. That connection is fast and immediate. But, every time that I hit the Share Screen button on the iMac G5 to try to connect to the MacBook Pro, I get a window with the blue barber pole spinning for two or three minutes as it is allegedly "Connecting to Mac Book Pro," followed by a window with a headline telling me that "Connection Failed to MacBook Pro." The text within that window goes on to say: "Please make sure that Screen Sharing (in the Sharing section of System Preferences) is enabled on the computer to which you are attempting to connect. Also make sure that your network connection is working properly."
Well, as I indicated, the PowerMac G4 has no problem sharing the screen of the MacBook Pro, so the Screen Sharing settings on the laptop are correct; and the iMac G5 can share the screen of the PowerMac G4, so its network connection is working properly in that regard. It is only in regards to sharing the screen of the MacBook Pro that the iMac G5 is not working properly.
The reason why I say that the issue must be unique to the one volume in question, let's call it "iMacG5 Music," is that another Leopard volume on the same computer has no problem whatsoever in sharing the screen of the MacBook Pro. Whenever I boot up in that volume, let's call it "iMacG5 JMB," it makes a network connection with a registered user name immediately, and it is able to share the screen of the MacBook Pro within a second of my issuing the command. In sharp contrast to the success of the iMacG5 JMB volume, the iMacG5 Music is unacceptably slow (several minutes slow!) in making a network connection with the MacBook Pro, and it always fails to share the screen of the MacBook Pro, preferring instead to take about three minutes to attempt the connection, before announcing its failure.
Since the iMacG5 Music volume makes an immediate network connection to the PowerMac G4, as well as sharing the screen of the PowerMac G4 the moment I ask it to, I have concluded that the hardware of the iMac G5 is just fine. The problem seems confined to the system software and/or associated networking files that are unique to the iMacG5 Music volume. I just don't know what those files could be, or where the problem lies, so I've issued this call for help.
Let me add one more little twist to this puzzle which baffles me even more. I use external LaCie Firewire drives as clone backups of my Macs. As part of my trouble-shooting process, I booted up from the cloned versions of the iMacG5 JMB volume and the iMacG5 Music volume. What I learned surprised me!
The iMacG5 JMB clone worked just fine in making a fast network connection to the MacBook Pro, as well as sharing the screen of the MacBook Pro. I expected that. What I did not expect was that the iMacG5 Music clone was also able to make a fast network to the MacBook Pro, as well as share its screen!
Yes, that's right. It's weird! Screen sharing works OK when I start-up from the clone of the iMacG5 Music volume, but it does not succeed when I boot up on the source itself! I was surprised to find that out, but I'm glad I did.
(Over the past few days since I executed the last clone, I did use Drive Genius to de-frag the source volume, and maybe that has contributed to the problem I am now encountering. But it's hard to say, since nothing else seems to be amiss.)
One solution, I suppose, would be to sync the clone back to the source. But, before I do that, I'm just wondering if anyone has a clue as to the nature of this problem on the source volume and what I might do to remedy it—short of re-installing the system software or restoring from the clone. Anyone have any insight to this problem?

CORRECTION #2:
Ignore the previous "CORRECTION" post.
Oops, excuse me, I wrote that sentence correctly the first time.
I was trying to point out that the ability of the iMac G5 computer to connect quickly and effectively to the PowerMac G4 when booted up into the iMacG5 Music volume was an indication (to me, anyway) that there is nothing wrong with the computer's hardware, nor its network connection ability, but that the problem lay somewhere in the files/settings used to connect to the MacBook Pro, which it cannot accomplish.
This is what happens when I get engrossed in one of these technical morasses and it ***** me into its vortex all through the night... time for bed.

Networking problem after a zone is created and installed

Hi all,
I've got a networking problem after a zone was created and installed on a Solaris 10 box. The box was configured with two NICs, one (e1000g0) with a public IP address, the other one (e1000g1) with a private IP address and connected to a local switch. All worked fine so far.
Then I created a local zone with shared networking (e1000g1). The zone has a private IP address which is in the same subnet as e1000g1 on the global zone. After some time, I noticed that I could not access (ssh, ping) the global zone. Then after some time, the global zone became available. The problem happened quite frequently.
Also I observed that: 1) When the global zone was unavailable from outside, it was available (ssh, ping) from another box within the same subnet (e1000g0); 2) If I shutdown e1000g1, the problem was gone.
Any idea what caused this problem?
Many thanks,
Xiaobo

The problem resolve after restart the whole XI system. is there any other way to solve the problem without restarting the whole xi server. Because i have tried to stop and start the communication channel but still doesn't work until restart the xi. server.
Please advise.
Thank you and Best Regards

Check JDBC FAQ note 831162
7. Network-Level Connection Problems
Q: The TCP/IP connection to my database host is running over an unreliable network connection, i.e. the connection is sometimes interrupted. Consequently, I sporadically receive an SQLException regarding a closed connection in the system trace or audit log or the connection as well as the JDBC Adapter channel are hanging.
How can I work around this connectivity issue?
A: Enable the "Advanced Mode" for the respective JDBC Adapter channel and select the option "Disconnect from Database After Processing each Message".
Note that this might put additional load on your DBMS due to the creation of a new database connection for each message.
If you are connecting to an Oracle database, also refer to question #10 for an alternative solution.

Is it possible to trap a Java Exception from within an XPRESS Rule?

Hellos.
I have a rule which invokes a Java method which queries an oracle DB table.
Due to network problems the oracle DBMS may reset the connection in some situations... which results in my Rule's invokation of the method giving an XPRESS exception because of an IO Exception. I want the chance to retry the query at least once before exiting the Rule and returning the error.
If it is possible to detect this Exception would someone please let on how its done.. I cant change the Java method all I wish to do in my Rule is to check if the <invoke></invoke> block threw an exception.

Testing HTTP URL that causes a network problem

Hi all,
I'm developping an applet for multiple unlimited files downloading using HttpConnection .
i want to implement the following feature :
In the case of an error occurring due to network problems during file download; the applet must be able to reconnect and resume the data transfer without downloading the entire file(s).
well i need to test this feature ; so i'm looking for some HTTP URL that can cause network probs so i can catch the error and retry connection etc...
can someone point me where to find such HTTP files for my test ?
thanks.

>
I can do this with FTP since it has commands to do
this but I don't know of any using HTTP unless one
uses a Servlet (or some other agent on the server) to
process a download request for a file starting at
some offset.
Actually i did it only using HttpConnetion class and inputstream using some work arounds to keep track of the offset during download (actually i'm saving the offset to a temporary proprieties file that i'm reading again to get specific offset and resuming the download from last point)
That is one way. You could also use an HTTP 'tunnel'
that forwards all requests to an HTTP server but
within the 'tunnel' you could at random close the
connection.I will go for throwing exception manually ; but i'm curious to know how an HTTP tunnel works.
thanks.

Software Update can't check for updates because of a network problem.

The software update app fails with following error msgs. But all network functions fine.
+A networking error has occurred: timed out (-1001). Make sure you can connect to the Internet, then try again.+
+Software Update can't check for updates because of a network problem.+
Deleted the software update plist files in $HOME/Library/Preferences, $HOME/Library/Preferences/ByHost, and HD/Library/Preferences, as per some posts. no effect. Problem persists.
Any Ideas?
Thanks

Same here
The last update I managed to do without problems was +Java for Mac OS X 10.5 Update 5+ - since yesterday the update process has become much, much slower and when I try to install +Security Update 2009 005+ and +iTunes 9+, it fails, usually with the aforementioned error, but also sometimes with Error 400 or Error 600, IIRC.

Issue configuring DAD on HTTP Server within 10g App Server

This time with a sensible subject...
I am trying to configure the HTTP Server within 10g Application Server with a DAD pointing to an instance hosted on the same server. However whenever I apply the DAD settings and re-start the server I am told the DAD is down. I have tried many permutations of the connection string all without success. Has anyone else encountered a similar problem and can suggest a resolution. I am carrying out the same steps as I would for a 9i HTTP Server and can only think it is a difference for 10g App Server.

Reviewing the mod_plsql services page, it says 'Module Loaded No'. I have reviewed the httpd.conf and oracle_apache_conf files and both suggest that mod_plsql should be started but this is obviously not the case.

Networking problem from Mac running Leopard to Mac running Yosemite

I have a curious networking problem and I would love some suggestions about what might be causing the problem and how to cure it.
I have a PowerMac G5/1.8DP running Mac OS X 10.5.8 Leopard with a number of external drives attached that I use as backup for all my RAW files. These are mirrored on three drives.
When I mount the drives on my iMac desktop, running OS X 10.10.1 Yosemite, over a gigabit ethernet network, two things are happening - 1. some of the folders are invisible (although they are actually there and populated on the PowerMac) and 2. spurious, empty, folders with odd names appear on the Yosemite desktop.
I have checked on the PowerMac to see that the folders all contain files - they do - yet over the LAN they appear as empty folders with gobbledygook names. This happens on all my Macs running Yosemite so it appears to be a Yosemite problem, rather than a Leopard problem. To further reinforce that I have also checked the PowerMac from three other Macs, running Tiger and Leopard, and they can see exactly what is on the drives, with no missing folders or oddly named folders.
The images show 1. the folder as it appears on the PowerMac running OS X 10.5.8, with two folders RAW Files 26 and RAW Files 28 highlighted, 2. the same folder seen on the Yosemite desktop with two folders, RAW Files 26 and 28, missing and 3. the same folder on Yosemite with three oddly named empty folders.
I am at a loss to know how to cure it and hope that someone will be able to help.

You can never, never, never transfer any installed version of PSE on any platform. You must always install from scratch on a new machine. By trying to do so you have made more work for yourself. You will need to download and run this:
Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
which will not seem to do anything, but is a necessary step to break the links within the program. Then you can go around and manually remove everything related to PSE that you can find, not only from Applications, but also from your username>library>preferences and the library at the top level of your hard drive>application support>adobe. You must go to these locations manually; spotlight will not help you with this type of search.
Then you can reinstall from your original media or from the download here:

Rogers Network Problem?

For the past two days my 3G and EDGE has been unstable. I have been constantly getting an error. Safari can't open the page. The error was: "Operation could not be completed. (kCFErrorDomainCFNetwork error 302.)"
I am using Rogers and since July 11th I've had no problems with my phone. Do you think its a Rogers problem or can I do something on my phone to help?
Thank you,
Austin

Rogers is working on the problem, They haven't given an ETA at the moment (most network problems are resolved within 48 hours of opening a master ticket). Unfortunately, since the problem seemed remote for the first 48 hours, the Ticket wasn't opened until late Saturday Aug. 23 2008. It's a good idea to give them a call, and add your account to the Master ticket. This will enable them to call you for any specifics on your particular problem if the issue isn't fixed past their own resolution and offers some insight into the troubleshooting of this issue. If any refunds, crediting or exchange issues come up, they will be able to refer back to the Master ticket and find who are eligible for this process.
