I just wanted the new services to be get published, I don't want to publish the previous services, I have seen one utility called "avahi-browser -r _http._tcp" but it is taking more time to unpublish the services [Service 'hello123' of type '_http._tcp' in domain 'local' on 3.0 disappeared] which are not available,Any suggestion will help me out, Thanks!!

org.openqa.selenium.WebDriverException: It is impossible to create a new session because 'createSession' which takes HttpClient, InputStream and long was not found or it is not accessible
Build info: version: '3.12.0', revision: '7c6e0b3', time: '2018-05-08T14:04:26.12Z'
I am getting this error randomly i want to know the route cause for this issue in IOS
There are multiple reason behind this issue. There are multiple ways to resolve this issues, depending upon, where these issues are coming from.
1)One issue which occur to me was DesireCapabilities.setCapability() key/value was not correct type. I have resolved this issue by just
DesiredCapabilities.setCapability("capabilities_variable","capabilities_value");
setCapability("appWaitDuration", "600000"); here 600000 was String instead of long or int
Check your setCapability type whether it String/int/long.
2) Check USB Connection is Laptop or Computer, if not connected than same issue.
3) ADB Server might be problem. So adb kill-server and adb start-server
4) Try to change USB and try it out.
5) Sometimes, it might be a proxy issue(Laptop/Desktop may have some proxy setup
in organization, since for Desktop/Laptops are connected with Mobile via TCP/IP Connection).
6) Sometimes, there might be permission required to access PORT (sudo ufw allow portnumber (UBUNTU SYSTEM))
7) Environment variable required Android_SDK_Home and Android Platform Tools path
**> Solution 1st**
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName", "xyz");
capabilities.setCapability("platformVersion", "6.0");
capabilities.setCapability("platformName", Platform.ANDROID);
capabilities.setCapability("appPackage", "com.hp.HPSupportAssistant");
capabilities.setCapability("appActivity", "com.hp.HPSupportAssistant.MainActivity");
capabilities.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, 6000); capabilities.setCapability(AndroidMobileCapabilityType.AUTO_GRANT_PERMISSIONS,true);
//desiredCap.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.ANDROID_UIAUTOMATOR2);
**Here comment below line and then run it will work**
desiredCap.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.ANDROID_UIAUTOMATOR2);
**solution 2nd Or keep above line in desired capabilities but before that do
run 3 cmd on cmd promt**
adb shell pm list packages -f > D://t.txt
adb uninstall io.appium.uiautomator2.server
adb uninstall io.appium.uiautomator2.server
desiredCap.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.ANDROID_UIAUTOMATOR2);

These types of intermittent issues are usually related to GRPC. An initial suggestion is to ensure that you are using at least GRPC version 1.0.0.
If you are using a Mac, then the maximum number of open file descriptors should be checked (using ulimit -n). Sometimes this is initially set to a low value such as 256, so increasing the value could help.
There are a couple of GRPC issues with similar symptoms.
https://github.com/grpc/grpc/issues/8732
https://github.com/grpc/grpc/issues/8839
https://github.com/grpc/grpc/issues/8382
There is a grpc.initial_reconnect_backoff_ms property that is mentioned in some of these issues. Increasing the value past the 1000 ms level might help reduce the frequency of issues. Below are instructions for how the helloblockchain.js file can be modified to set this property to a higher value.
Open the helloblockchain.js file in the Hyperledger Fabric Client example and find the enrollAndRegisterUsers function.
Add “grpc.initial_reconnect_backoff_ms": 5000 to the setMemberServicesUrl call.
chain.setMemberServicesUrl(ca_url, {
pem: cert, "grpc.initial_reconnect_backoff_ms": 5000
});
Add “grpc.initial_reconnect_backoff_ms": 5000 to the addPeer call.
chain.addPeer("grpcs://" + peers[i].discovery_host + ":" + peers[i].discovery_port,
{pem: cert, "grpc.initial_reconnect_backoff_ms": 5000
});
Note that setting the grpc.initial_reconnect_backoff_ms property may reduce the frequency of issues, but it will not necessarily eliminate all issues.
The connection to the eventhub that is made in the helloblockchain.js file can also be a factor. There is an earlier version of the Hyperledger Fabric Client that does not utilize the eventhub. This earlier version could be tried to determine if this makes a difference. After running git clone https://github.com/IBM-Blockchain/SDK-Demo.git, run git checkout b7d5195 to use this prior level. Before running node helloblockchain.js from a Node.js command window, the git status command can be used to check the code level that is being used.

Can anyone please help here why we are getting this problem and can any tell us can an application cause this impact on mashost ..????
First things first, check out the NFS service w/ svcbundle and svcs -- when it crashes, run:
# svcs -x nfs/client
on the client, and
# svcs -x nfs/server
on the server. I would expect one or both to be in a "maintenance" state. (You may see it fails to start properly at all). If it is in a maintenance mode, you should see a row marked "Reason:" that says why.
You might see "offline" -- in that case, startd will attempt to reboot the service multiple times and, if it fails after five attempts or hangs indefinitely, places it into "maintenance" state and stops restarting.
Check the logs in
/var/svc/log/<service-name FMRI>.log
There will be one on your client machine under "network-nfs-client:default" (probably, may have a name other than 'default' if it's been changed manually), and one on the server under "network-nfs-server:default"
See what you can glean from those.
svcbundle is all the time taking snapshots as backups of services, so you can try reverting to one of those.
# svcs -s nfs/server:default
svc:/network/nfs/server:default> listsnap
svc:/network/nfs/server:default> revert start [name_of_snapshot]
svc:/network/nfs/server:default> quit
# svcadm refresh nfs/server:default
# svcadm restart nfs/server:default
Make sure to include the ":default" tag, or if you saw a different tag from "svcs nfs/server" include it, that name defines an instance of the service, every running service is an instance.
If the process is failing to boot, you might have to look at the XML manifest under /lib/svc/manifest/network/nfs/ -- inside, you'll see dependencies (and services dependent on this one), then "exec_method"s, which define how the service starts, stops and restarts.
Instead of snapshots, you can can also restore it to default: use svccfg -s <FMRI> delete to clear it, then svcadm refresh <FMRI> and svcadm enable <FMRI>.
If the service is in maintenance state, once you've isolated and fixed the problem, you can manually clear that state by running svcadm clear <FMRI>.
I have installed Oracle ATG v11 with the commerce reference store, when I startup the production server and go to the url domain/crs/storeus I see the blank white page, and have the following error in the console:

I am assuming this error is related to endeca? I have downloaded CAS, Tools And Frameworks with experience manager and MDX, and Platform Services. Do I need to start these or have I missed a part of the endeca install?
The value of the configurationPath attribute in the DefaultFileStoreFactory.properties located at \localconfig\atg\endeca\assembler\cartridge\manager may be incorrect.
In OOTB CRS, we normally provide the following value for configurationPath attribute :
/ToolsAndFrameworks/11.1.0/server/workspace/state/repository/CRS
Could you please verify the .zip is present at path provided in DefaultFileStoreFactory.properties.
Just check if you are able to connect the below url:
host:15000/admin?op=stats
If you are able to connect this URL, then MDEX is running. Also, you can login to the experience manager and check if the dgraphs and dgidx are running.
If you are not able to connect then check all the services are(tools and http) running and accessible. You can check the endeca logs to debug further.
Your DGraph is not (yet) started.
(Hit this URL in your browser and verify: http://localhost:15000/graph?node=0&profiles=sitegroup.siteGroupUS|NoPriceRange|site.storeSiteUS&offset=0&nbins=0&irversion=640&format=xml)
Possible reasons are:
You did not run baseline update from ATG (from
ProductCatalogSimpleIndexingAdmin dyn/admin component).
You did not run promote content (from your Endeca App's control folder).
Your Services are not working properly (or not started at all). Check that Platform Services and Tools And Frameworks are started.
The solution is to properly define the value for the property configurationPath=E:/Endeca/Apps/CRS/data/workbench/application_export_archive/CRS in "DefaultFileStoreFactory.properties"
If you are using the OS as Windows then define this path as Unix style as shown above.
this is my first post so I will try to be as descriptive as possible. Please let me know if there is anything missing:
So I am trying to install Oracle Express 11g, after I download the zip file "OracleXE112_Win32" - I unzip it, and open Disk 1 then setup. I go through the entire installation process without any problems. However when I go to open "Get Started" I come across the following error:
"Windows cannot find 'http:/.127.0.0.1:%HTTPPORT%/apex/f?p=4950'. Make sure you typed the name correctly, and then try again. -- After googling this, I was told to change %HTTPPORT% to 8080.
If I do this when I click on "Get Started" the following error shows up:
"Firefox can' establish a connection to the server at 127.0.0.1:8080."
I need this to work, so that I can sooner or later connect this to my eclipse, so that I can start doing my homework for my Java Programming class. Any help is greatly appreciated, thank you so much!
I have found one solution for this problem. In order to explain my solution, I have used some aliases referring to my real parameters. These are:
[ME] = my user name
[MYHOST] = my current workstation hostname (netbios name as well)
[MYHOST.mycompany.com] = my worksation's fully qualified domain name
At the beginning I had the same situation as mentioned above: I was unable to connect to the apex service even after successful installation.
First I have used the tnsping oracle utility:
C:\Users\ME>tnsping MYHOST
This was the answer:
TNS Ping Utility for 32-bit Windows: Version 11.2.0.2.0 - Production
Copyright (c) 1997, 2010, Oracle. All rights reserved.
Used parameter files:
C:\oraclexe\app\oracle\product\11.2.0\server\network\admin\sqlnet.ora
Used HOSTNAME adapter to resolve the alias
Attempting to contact (DESCRIPTION=(CONNECT_DATA=(SERVICE_NAME=))(ADDRESS=

(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.106)(PORT=1521)))
TNS-12541: TNS:no listener
You see above a lot of currently active different IP addresses. Only the most important 127.0.0.1 is missing. I work on notebook so the network is "almost always" changing (WLAN, 3G, HSDPA, Ethernet etc.) only the localhost is fixed. And that was the real case of the trouble. (When I was working at the office environment connected to the office network it was also working.)
When I was in this situation I also started to use the lsnrctl oracle utility.
I have seen the following:
LSNRCTL> status
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
STATUS of the LISTENER
------------------------
Alias LISTENER
Version TNSLSNR for 32-bit Windows: Version 11.2.0.2.0 - Production

Instance "PLSExtProc", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully
You can see that the service for the apex at 8080 port is missing !!!
I have tried also the normal ping which worked perfectly:
C:\Users\ME>ping MYHOST.mycompany.com
The result was:
MYHOST.mycompany.com [fe80::c27:54a4:1600:86a4%26] ping
response fe80::c27:54a4:1600:86a4%26: time<10 ms
...
You can realize the IPv6 address also exists in my tnsping trial as well.
So I have decided to define MYHOST in my local hosts file directly:
127.0.0.1 localhost MYHOST MYHOST.mycompany.com
Testing now with ping:
C:\Users\ME>ping MYHOST
And the answer:
MYHOST.mycompany.com [127.0.0.1] ping:
response 127.0.0.1: byte=32 time<10 ms. TTL=128
...
At this point I have restarted (stopped and started again) the both running Oracle services (just for sure):
OracleServiceXE
OracleXETNSListener
And look the miracle:
C:\Users\ME>lsnrctl
LSNRCTL for 32-bit Windows: Version 11.2.0.2.0 - Production

You can see the important line with PORT=8080 and service XE instance.
So I am happy the getting started URL is working again.
What browser are you using? I experienced the same issue with Chrome. Download firefox, Right click the "Get Started With Oracle Database 11g Express Edition" icon and change the "opens with" option to firefox.
Simple solution:
You need to directly tell where your http port is. To do so; open up the folder where your Oracle is stored and navigate to server folder( in my case C:\Oracle\oraclexe\app\oracle\product\11.2.0\server) in that folder right click to Get_Started file and choose properties. There you can hand type your http port which is usually 8080 in my case: ....127.0.0.1:8080/apex/f?p=4950
The problem should be solved.
Hope this helps you get through it..
Pinar U.S.
Right Click on the "Get Started" icon and click on the properties and select General tab. Click on change button and select other browser installed in your system other than the current one . after setting this up, you'll be able to open the panel.
I also experienced the same problem for this go to start-> all programs -> Oracle Database 11g Express Edition and right click on get started and click open file location and drag and drop the "Get_Started" to your browser
Ok, I found the solution. Right click on icon of "Get Started With Oracle Database 11g Express Edition", then "properties". Then click "General tab" and then you will see option "change", click on that and then select your browser, click "apply" and "ok". And then start the Database again.
Drag and drop get started link into browser address bar worked great for me, I tried EVERYTHING else, adding port to hosts, changing port in properties etc. nothing worked, until I dragged and dropped... So damn simple, wish I did that hours ago
Your solution is partially correct buddy. You need to match the entries in the file:
C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN\listener.ora
(the entries with the --> mark)
:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
--> (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
--> (ADDRESS = (PROTOCOL = TCP)(HOST = myserver.company.com)(PORT = 1521))
)
)
:
With the entries in the file:
C:\Windows\System32\drivers\etc\hosts
(the entries with the --> mark)
:
--> 127.0.0.1 localhost
--> 1.2.3.4 myserver myserver.company.com
:
Finally, under Administrator account do:
C:> lsnrctl stop
C:> lsnrctl start
Solved. No need for changing name, no drag & drop either.
