Unable to Ping IP when using route redistribution
Hi Everyone,
I have below setup
R1 is running EIGRP and connected to R2 via EIGRP
R2 is Running OSPF and connected to R3 via OSPF.
R2 is doing the redistribution of eigrp to ospf and vice versa.

Need to know even the route is in routing table why i am umable to ping the IP 10.0.23.3?
Also unable to ping the loopback IP of R3 below
R1# ping 10.1.10.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.10.1, timeout is 2 seconds:
Success rate is 0 percent (0/5)

Hi Alain,
Yes R3 was getting the filtered EIGRP routes from R1 via R2.
i removed the distribute list on R2 and ping worked fine now.
I understood now why ping was not working earlier as R1 int IP 10.1.12.1 was dropped by the distribute list.
Now i added this to ACL 1 on R2 which is used by distribute list on R2 and ping works fine now while using distribute list on R2.
Best regards
Mahesh

Unable to parse query when using dblink in forms 4.5
Hi,
I have created a query that uses a DBlink because I need to do query on a table located on another dbase. I've used the query on creating my report using Reports 6i. The report needs to be called from a menu on our system, which was developed under Developer 2000 (forms 4.5). The problem is, when I tried to access the report from the menu, it returns the error 'unable to parse query'. What I did after getting error was to create a dummy module using Forms 6i, and call my report from there. It worked fine.
By the way, the table that I'm accessing using the dblink is under Oracle 9i dbase, and the dbase of the system that I've been working at is Oracle 8i.
I don't have any idea on what's causing this error. Is there a compatibility issue when using a dblink located in Oracle 9i database with forms 4.5?
Thanks!Hello,
Not sure if it is the good answer, but I know that Forms does not recognize dblink and owner.object syntax. You have to create a simple synomym that point to the distant object and use this synonym within Forms.

really have a hard time when leaving the computer on when attending other matters in the house. When returning, the screen is completely black and unable to wake(?) by touching the mouse or touch pad to put my password and be able to use the computer. When I move the mouse pad looks like I am using the eraser like in photoshop and it clears the screen little by little. Now I am able to point to the middle of the screen and erase the area where the password is in order to get to the screen and use the computer again. Anyone else having this problem? Took the laptop to the apple store near home and they told me there is nothing that can be done and I have to wait untile the new operating system, Mountain Lion comes out and supposedly this will fix the problem. HELP!!!!
I was so frustrated I call the Apple Tech Support and they walked me through. It has been doing great. The screen still turns black but now, when I touch the mouse or touch pad, I get the password prompt. The Apple Store did not help but talking the the Apple Tech has helped a lot. Thank you.

Unable to close browser when using Adobe Interactive Form
Hello,
I'm using an Interactive Form in my Web Dynpro application. Everything works fine, but when the view with the Interactive Form is active, I am not able to close the browser window anymore. Moving to another view is also not possible.
I already changed all the options of the Interactive Form but always the same behaviour.
I am developing on Web AS 6.40, Service Pack 11. ADS is installed also with Service Pack 11.
Adobe Reader is Version 7.0 and Adobe Designer is Version 7.1
Has anyone an idea what's wrong?
Thanks for your help!
Best regards
ChristianHi,
I am facing a problem with viewing SAP interactive forms.
I have the SAPForms.api in Adobe reader plugins but is outdated (19th apr, 05). How do I get the new one and how do I register it ? This same scenario works on a colleague's machine with same config except the SAPForms.api which is latest. (Nov, 05)
Any pointers will be highly appreciated.
Thanks,

Unable return sucessful validate when using signature pad
I need to verify that the user signed the form. We are using a signature pad to capture the electronic signature. And then using the code below in a button to validate. If the signature is left blank I do get the message that the "Signature is not valid: signature is blank". But if I complete the signature field I do not get anything back.
var f = event.target.getField("form1[0].S1[0].SignatureField1[0]");
// Validate the signature field:
var status = f.signatureValidate();
/* signatureValidate method returns one of the following integer validity status values:
-1: not a signature field
0: signature is blank
1: unknown status
2: signature is invalid
3: signature is valid, identity of signer could not be verified
4: signature and identity of signer are both valid
// Obtain the signature information
var sigInfo = f.signatureInfo();
if (status < 3)
var msg = "Signature is not valid: " + sigInfo.statusText;
else
var msg = "Signature is valid: " + sigInfo.statusText;
// Display the status message:
app.alert(msg);;
I have also tried just returning the status using
app.alert("Signature status: " + status);
When I leave the signature blank I get "Signature status: 0"
When I fill in the signature, I don't get the message box.
Is there another command for validating with a signature pad.
Thanks,
Velvettry using the status property. This is currently working for me.
var oState = event.target.getField(("form1[0].S1[0].SignatureField1[0]").signatureInfo().status; -

Iomega ZIP drive-constantly unable to read disks when using on both PC&Mac
I'm constantly having problems with Iomega ZIP disks:
-can't be read by PC or MAC
-needs reformatting
I have to erase the disk using disk utitlities and make sure its FAT 32 (not 16) for the PC to read it.
However this is only temporary as the disk will again become unreadable by both machines.
Is this because i'm constantly using is on both machines?
Does anyone else have this problem?
Any solutions?
This appears to have started since the last major OS X upgrade - i.e 10.3 to 10.4.
Cheers
TashaYou may not want to hear this - but the best thing to do is to get anything that matters off Zip disks, and never touch them again. They're inherently unreliable, and you're much better off using CD-R or DVD-R.

I want to change Router2's Operating Mode from "Gateway" to "Router" because I
want to turn off NAT on Router2 so that I can access all computers attached to
Router2 by their individual IP instead of using port forwarding at Router2.
The problem is after the mode change from "Gateway" to "Router", and regardless
whether I disable RIP or enable RIP, and on what interfaces it is enabled, computer
192.168.2.160 does not have internet connection.
Observations:
[0] INTRAnet works as I can reach computer 192.168.2.160 from computer behind Router1
192.168.1.x and vice versa.
[1] ping and traceroute *work* on Router2 itself using the built-in dianostic tool.
[2] nslookup on computer 192.168.2.160 always works on new lookup. It uses
192.168.2.1 as the resolver.
[3] tcptraceroute stops after step 2:
[pre]
# tcptraceroute yahoo.com
Selected device enp2s0, address 192.168.2.160, port 45999 for outgoing packets

This is not expected because NAT to internet should still be done by Router1, no? Computer
behind Router1 with IP 192.168.1.x has internet connection.
[5] It looks like I cannot change the Routing Table Entry on Router2. I do not think I need to change anything,
just an observation.
[6] If I use LAN to LAN connection, then both intranet and internet works. [The internet IP of Router2 can be
anything not in the same subnet of the Router1, and DHCP on the local side should be disabled to avoid conflict
with the the DHCP on Router1].I have a question. Unfortunately in order to ask my question, I have to have a lengthy description of my setup. Basically, I have a second Linksys router in "router" operating mode with NAT disabled connected to the Verizon router, and I have a computer which is in a different subnet (192.168.2.x) behind the Linksys router. This computer can communicate with computers behind Verizon router in subnet (192.168.1.x), but cannot reach internet. This is a simplified version of my question, full details are in the original post.
If I setup the Linksys router in "gateway" operating mode, which means with NAT enabled, then both intranet and internet works, but there is no easy way to setup port forwarding for 10 compueters in 192.168.2.x network to communicate with 10 computers in 192.168.1.x network.
If I setup the Linksys router in a LAN to LAN configuration with Verizon routers, but this way all computers are in the same subnet, I want them to be in different subnet for access control and things like that.
I hope this makes things a little clear.
Thanks. -
When using the camera downloader in Adobe Bridge CS6 with Nikon D5200 we are unable to see previews of the photos and it is very slow to download. The issue occurs under a the users rights, but not under admin level. This is a new issue.
Hi Jdentremont,
Lync client gets user photos by first querying the Address Book Web Query (ABWQ) service on the server, which is exposed through the Distribution List Expansion web service. The client receives
the image file and then copies it to the user's cache to avoid downloading the image each time it needs to be displayed. The attribute values returned from the query are also stored in the cached Address Book Service entry for the user. The Address Book Service
deletes all cached images every 24 hours, which means that it can take up to 24 hours for new user images to be updated in the cache on the server.
To troubleshoot your problem, please follow the steps below:
1. Navigate to
“X:\share\1-WebServices-1\ABfiles\000000000\000000000” folder. (ABS file share)
You should see some photo files in this folder as the following screenshot.
2. Delete all the files in this folder.
3. On test PC, delete local cache files.
%userprofile%\AppData\Local\Microsoft\Office\15.0\Lync\[email protected]
4. Sign-in Lync with the test account.
5. Go back to the ABS file share, check if there is any Photo file in the folder.
Best regards,
Eric

PDF: Unable to print a document as PDF from APEX when using the BI Publishe
Hi,
From an APEX application, I am unable to print a document in a PDF format when using the Oracle BI Publisher.\
Here is the configuration:
1) Server A is W2K3 and hosts the Oracle BI Publisher server, with IP address ip01.
2) Server B is a OEL5.2 and hosts the database server of the APEX application, with IP address ip02.
3) Machine C is a W7 desktop from which through an URL both the APEX applicationn and the BI server are accessed, with IP address ip03.
4) The APEX application is configured with the following to use the Oracle BI Publisher:
- Printer server: Advanced (requires Oracle BI Publisher)
- Printer server protocol: HTTP
- Printer server host address: ip01
- Printer server port: 9704
- Printer server script: /xmlpserver/convert
- Network services are enabled (at least I did get any warning/error message)
From C, I access the the APEX application through its URL, if I try to download a page by selecting PDF in the download section of the interative report section for that page, I am unable to open if and get the error:
<file>. pdf file can not be opened because the file type is not supported or because it is damaged (because, for example as an e-mail attachment is not sent and correctly decoded)
Yet, still from C, I am able to open any other PDF document.
The same way, still from C, acessing the APEX application through its URL, I have a query report defined with a PDF output format. Then, when I test the report (Test Report in the Report query) for that query, I get the error:
ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.
At first sight this could be a wong entry in the priinter configuration for APEX. But with this address, through the URL I can log in to the Oracle BI Publisher server.
Does someone has an idea what the problem could be?
Thanks for any tips.How are you trying to print to pdf?
Don't go via PostScript or Acrobat Distiller, which are old deprecated technology.
You use:
Menu > File > Print > PDF (button bottom left) > Save as PDF…
