Can't get 2 VM nodes to talk to each other on OEL7

Greetings -
I am planning to install RAC 11gR2 on OEL7. I got the Oracle VM machines up and running. I can access internet successfully with no issues. Also if I am on Node-1 and ping its IP, it works fine.
But when I try to ping Node-2 from Node-1 and vice virsa, I get unreachable message.
Below is my setup hots setup:
[oracle@racdev01 Desktop]$ cat /etc/hosts
# loopback
127.0.0.1       localhost.localdomain        localhost
# Public
192.168.56.71   racdev01.localdomain         racdev01
192.168.56.72   racdev02.localdomain         racdev02
# Private
192.168.10.1    racdev01-priv.localdomain    racdev01-priv
192.168.10.2    racdev02-priv.localdomain    racdev02-priv
# Virtual
192.168.56.81   racdev01-vip.localdomain     racdev01-vip
192.168.56.82   racdev02-vip.localdomain     racdev02-vip
# SCAN
192.168.56.91   rac-scan.localdomain         rac-scan
192.168.56.92   rac-scan.localdomain         rac-scan
192.168.56.93   rac-scan.localdomain         rac-scan
Pinging both public & private IPs from node-1 to node-2 and vise-versa keeps failing:
$ ping racdev02
$ ping racdev02-priv
>> My network:
Node-1: Ethernet (enpOs8) => 192.168.56.71   (public)
Node-1: Ethernet (enpOs9) => 192.168.10.1     (private)
Node-2: Ethernet (enpOs8) => 192.168.56.72   (public)
Node-2: Ethernet (enpOs9) => 192.168.10.2     (private)
Below are the setup for my 3 adapters:
I've been trying for days to get these 2 nodes to talk to each other. I'd really appreciate your help in resolving this issue..I can't proceed with RAC installation unless I get these machines talking to each other..
Thank you so much !
@AJ

1. "Note. The SCAN address should not really be defined in the hosts file. Instead is should be defined on the DNS to round-robin between 3 addresses on the same subnet as the public IPs. " You may specify as much IPs for SCAN as you wish but the first one only will be used.
2. VIPs should be on the same NICs as physical IPs.
3. Probably I missed something but I found nothing concerning 3 NICs.
4. OL7 is supported starting from 11.2.0.4.
5. It is possible to configure firewall instead of disabling it.
6. It is necessary to configure OS, create user(s) and groups according to Installation Guide or use validator rpm.
7. It is possible to configure disks with udev and not to use oracleasm.

I can't get the correct node (a real beginner)

I have an XML file which looks like this:
[code<lawyer>
     <Country>Singapore</Country>
     <Company>Allen & Gledhill</Company>
</lawyer>
<lawyer>
     <Country>Singapore</Country>
     <Company>Allen & Gledhill</Company>
</lawyer>.
</Lawyers>
But I can't get the right node names and values.
Here is my code:
File file = new File("lawyers.xml");
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.parse(file);
NodeList nlLawyers = doc.getElementsByTagName("lawyer");
for (int i = 0; i < nlLawyers.getLength(); i++) {
     Element elLawyer = (Element) nlLawyers.item(i);
     NodeList columns = elLawyer.getChildNodes();
     for (int j=0; j<columns.getLength(); j++) {
          Node col = columns.item(j);
          String colName = col.getNodeName();
          String colVal = col.getNodeValue();
          System.out.println(colName + ": " + colVal);
}What I would like to print out would be something like this:
Country: Singapore
Company: Allen & GledhillBut I am getting extra nodes and cannot get the text values. Here is the output I am getting:
#text:
Country: null
#text:
Company: nullI don't understand this output at all. Please help me get the list of node names and values?
Thank you.

It seems that the #text nodes represent the whitespace between the formal nodes. Also, the nodes that I want to extract have a NodeTypeValue of 1. Once I had determined that I had the correct node, I had to get its child node to get the text. Here is the final code:
File file = new File("lawyers.xml");
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.parse(file);
NodeList nlLawyers = doc.getElementsByTagName("lawyer");
for (int i = 0; i < nlLawyers.getLength(); i++) {
     lawyer = new Lawyer();
     Element elLawyer = (Element) nlLawyers.item(i);
     NodeList columns = elLawyer.getChildNodes();
     for (int j=0; j<columns.getLength(); j++) {
          Node col = columns.item(j);
          if (col.getNodeType() == 1) {
               String strColumn = col.getNodeName();
               Node txt = col.getFirstChild();
               String strValue = txt.getNodeValue();
               System.out.println(strColumn + ":\t" + strValue);                         }
     } // for each column
} // for each lawyer

Can't get BAPI return node in web dynpro!!

I'm calling BAPI in web dynpro, I already map the <BAPIName>_Input->Output->Return to our custom controller context. I can get the value of some other output parameters in Output node, but can't get the return node.
wdContext->currentOutputElement is Ok, but wdContext->currentBapiReturnElement is null, what is the problem??!!!
Can anybody give me an hint, or give me a example to access the return value of Bapi??
Thank you very much!
Regards,
Xiaoming Yang

Hi Vitaliano,
Thanks for your reply.
yes, I've call the invalidate method, like this:
wdContext.currentBapi_Trip_Create_From_Data_InputElement().modelObject().execute();
//wdContext.nodeBapireturn().invalidate();//do I need this?
wdContext.nodeOutput().invalidate();
But it still can't work!
The return node is a child note of Output, does it ok?
Thank you!

(ios5 ipad bugs)I can't get changes of album art, artist, album and other tags to show up in the iPad music player, but they show up correctly in the iTunes device view. Certain random songs do not sync correctly. Wifi sync hasn't worked yet.

(ios5 ipad bugs)I can't get changes of album art, artist, album and other tags to show up in the iPad music player, but they show up correctly in the iTunes device view. Certain random songs do not sync correctly. Wifi sync hasn't worked yet.
I mostly use technology for education and professional audiovisuals and lights.
I don't sync music because I use music from at least 4 different computers. (manually mange music)
I use my iPad to play performance tracks for church and a local gospel group out of our church, Won4Christ.
I chose to buy the iPad because the laptop of one of the group members (dellxps running iTunes) was randomly losing and mixing up music and I wanted a more stable option that was bigger than my iPod touch.
I tried to add some data to music libraries that I previously added to my iPad, but the data only shows up when looking at the device in iTunes.
Wifi sync has not worked on either my laptop or desktop ( both running windows 7 enterprise 64 and newest iTunes) not really a big issue, but very annoying
When browsing through library playlist albums on the iPad, random artwork shows up on playlists with no artwork that you touch while dragging, and it does not go away until you change to another navigation tab and back.
Random songs out of hundreds that I added showed up in iTunes grayed out with a sync circle beside them. Those songs would play back okay on the iPad but were unplayable through the iTunes device view. I had to delete the songs manually through the library along with the playlist and add them again.
These seem to be major stability bugs in the "new" music app and iTunes. My only option right now seems to be to delete the songs that I want to change and re-add them with the changes already applied rather than changing the id3 tags and artwork on the existing music. I hope apple will release updates to resolve these issues.
Thank you for actually making it to the end of this manuscript of annoyances.

Just wondered if anyone had any other suggestions.

First try killing Words. When on the home screen double press the HOME button, then swipe the screen image of Words up to close it.
Next, reset your iPhone by holding HOME and SLEEP until an Apple logo appears. If the problem is not resolved delete the app from your phone, reset the phone again, then reinstall the app.

No, and if I noticed anyone that I allowed to use my iPhone checking my email which is the same as opening any of my snail mail without my permission, that would be the last time they used my iPhone.

NetWeaver XI components are not talking to each other

I am an XI consultant, i dont have proper Basis support at my client, since they are fond of only ABAP stack.
They installed netweaver xi from the market place.
I am unable to import any SWCV (even SAP BASIS) from SLD to IR and IR menu is blank.
Unable to find list of adapters in Integration Directory.
RWB -component monitoring is blank .
SLD- creation of products,SWCV,Technical Sys,Buss Sys is possible.
In conclusion i can say that they all are not co-operative and not talking to each other
And also i want to know wheather xi 7.0 is compatable to databases Oracle 8.0.3 and Oracle 8.0.4

Hi Venkata,
Does the XI post Installation steps done by the team or not? It seems that there is some steps missing while doing the XI installation. Talk to to the BASIS team and tryu to find out the solution.
>>> Unable to find list of adapters in Integration Directory.
Check thisblog for it:
/people/venugopalarao.immadisetty/blog/2007/03/15/adapter-engine-cannot-be-found-in-integration-directory
>>> And also i want to know wheather xi 7.0 is compatable to databases Oracle 8.0.3 and Oracle 8.0.4
In my view, yes. XI is compatible with all the versions of Oracle Database above version 8 but never tried it.
Reward points if helpful. *

HT204387 Why can't my ipad2 and iPhone4 and 5 recognise each other as devices using bluetooth?

Why can't my ipad2 and iPhone4 and 5 recognise each other as devices using bluetooth?
Bluetooth should allow me to connect to other devices to transfer data like photo's, music, files, whatever between my apple devices and non apple devices.
Other phones allow me to do this..........what is happening here?
An unhappy apple devices owner.
I want to know who I complain to if this is how Apple devices operate.
Any answers anyone.

When using the migrate tool to migrate from windows to mac, can you use ethernet to connect the computers to each other?

When using the migrate tool to migrate from windows to mac, can you use ethernet to connect the computers to each other? In the Migration tool, I was only given the option of choosing the computer when it appeared on the same network, and didn't see an option to connect them to each other. Even though they're both connected to the same network with a wired connection, the migration is painfully slow.

Yes. The following quotation is from About Windows Migration Assistant
These are the preferred network connections, in order:
Use a CAT6-certified Ethernet cable that is in good condition to connect the Ethernet port of the PC directly to the Ethernet port of the Mac or Ethernet adaptor (USB or Thunderbolt). You shouldn't use an Ethernet cable that has any kinks in it or is missing connector tabs.
Use CAT6-certified Ethernet cables that are in good condition to connect the Mac and PC to your home network router/hub/switch. You shouldn't use an Ethernet cable that has any kinks in it or is missing connector tabs.
For wireless, use the fastest wireless signal possible (802.11n 5Ghz). Try to have the PC, Mac, and the wireless access point all in the same room close to each other.

HT5621 My Apple ID on my iphone icloud is different to my apple id on my pc icloud. As a result, they don't talk to each other. My phone icloud account is for 25 Gigs. but my pc has 5 Gigs but none used.

My iPhone iCloud uses one of my Apple ID and the account is a 25 Gig storage. I tried to set up icloud on my pc and for some reason it seems to be linked to a different Apple id with a 5 Gig account. Obviously the two don't talk to each other but I don't know how to change one or other so they will sync.

Try the following....
Go to Settings>icloud, scroll to bottom of screen and tap Delete Account. Then log in using a different ID.

How can i get my iphone on straight talk to send and receive mms?

I have an iPhone 4 on straight talks network. I have never been able to send or receive mms messages to anyone other than a device with iMessage. How can I get it to work? I dont want to change to a Galaxy or any other kind of phone, but I will if this doesnt get figured out. Straight talk says its an issue with Apple products. Please help!!

Hey Jstugelmeyer,
First, I would go through these three steps:
Restart your device.
Update to the latest iOS Software.
If you are trying to send a message to multiple recipients and you type in each contact manually instead of using the contacts list, make sure you tap return instead of space to separate each one.
Then, if you still can't send or receive MMS messages:
To send and receive MMS messages on your iPhone, verify that your wireless carrier supports MMS2.
Ensure that MMS Messaging is turned on in Settings > Messages.
Verify that your phone is able to access cellular data.
Some carriers allow you to edit your APN (Access Point Name), which may prevent MMS from working.
If you are roaming outside your calling area, make sure you have Data Roaming turned on in Settings > General > Cellular to send or receive MMS content.
While on a phone call, you will be unable to send or receive MMS messages when using an EDGE, GPRS, or any CDMA cellular data network. After the phone call ends, you will receive any incoming messages. If you tried to send an MMS message, you may need to send it again.
If the issue persists and your wireless carrier has confirmed that your wireless account is provisioned2 for MMS, restore the iPhone.

Outlook 2010 Office 365 and Exchange -- can't get them to talk to each other

I saw similar question posted with no answer.
Have Office Outlook 2010 on HP Pavillion dv7 running Windows 7 Premium and Office 365 on HP Envy x 2 running Windows 8 and can't get either of the Outlook programs to talk to Exchange. They both ask for passwords and none of the ones I try seem to
work. Yet the email program that came with the HP Envy x2 (part of Windows 8?) manages my Exchange emails as well as my gmail and bellsouth.net accounts.
If for some reason I can't link Exchange to more than one version of Outlook (I'd like to connect to both), suggestions for connecting Exchange to Outlook 365 would be welcome.
Suggestions?

Make sure you have installed the latest SP for Office 2010 and all the other updates. It also requires the PRO PLUS version of Office for all features to work as expected, if you are using Standard or Home this might be the problem. Check here for more info:
https://support.office.com/en-us/article/Outlook-license-requirements-for-Exchange-features-46b6b7c5-c3ca-43e5-8424-1e2807917c99?ui=en-US&rs=en-US&ad=US
Other than that, make sure you use the full [email protected] credentials

Cant get 2 iPads to talk to each other with FaceTime.

I have ipad2 , recently bought 10 yr old one too. His iPad is registered to my apple I'd, I think he is too young to have own ID. I have set up his iPad with a gmail address for FaceTime and I have another address for FaceTime on my iPad, so we can talk together over the summer when he is going to stay with family overseas. Both email addresses are linked to my ID. I've tried every which way I can but can't get FaceTime to work. He is on my contact list, I am on his, but each time one of the iPads places a call we get call failed. We have wi-fi, so that is not the problem. All email addresses are verified, and the email address for video calls is different on each iPad. Any one got any idea why it won't work? I so want it to work and not have to resort to skype!

Did you remove the Apple ID email address from one of the devices? Perhaps the devices are trying to reach each other at that same email address. Even if you associate another email address to the one device, you still have to remove the Apple ID address from that device or it will use that address as the one at which it can be reached for FaceTime.

How can I get the number of distinct records that each field of a DB table has?

Hi everyone,
I would like to know how to get he number of distinct records that each field of a DB table has. When tracing a SQL statement either in ST12 or ST05, in the plan execution, if the sentence made useage of an index, then I can click in the index name and see this kind of information (no. of distinct values for each field of that index).
Can I do something like this but with the whole fields of a table?
What I have found until now is in Tx ST10; I search for whatever kind of table statistics and then use the function of "Analyze table" (which takes me to Tx DB05). In here, I can enter a table and up to 5 fields in order to get the information that I want.
Is there any other way to do this?
Regards,
David Reza

Hi David,
You can export the same to excel and sort as per requirement.
Sorry is that what you are looking for ?
