Am preparing some code for migrating from VB&SQL Server to our new solution based on JAVA&Oracle DB, so am trying to connect on the SQL Server to query some data and then to put them on our new oracle tables, but when I try to connect via this code:
DriverManager.registerDriver(new com.microsoft.sqlserver.jdbc.SQLServerDriver());
Connexion con = DriverManager.getConnection("jdbc:sqlserver://192.168.10.97:1433;databaseName=ArchiveCCE", "test", "test");
it keeps show me the following error :

Also, i am facing the same issue while running the above command in my Virtual machine as well.
I set up openshift V3 all-in-one on a VM in the cloud so how can I contact it as the address is private and internal.
I think I have to start Vagrand with some magic parameters but I haven't clue about them.
Thanks
When testing Openshift, I deployed the all in one VM in an Openstack instance.
To be able to access Openshift, I had to change master-config.yaml configuration (which in the VM is located in /var/lib/origin/openshift.local.config/master/master-config.yaml)
Changing all references of the internal IP (10.2.2.2) to my public domain (https://my-domain.com:8443) did the trick.
I also had to regenerate the server certificates, including the public IP of my Openstack instance, this way:
oadm ca create-server-cert --cert=master.server.crt --key=master.server.key --signer-cert=/var/lib/origin/openshift.local.config/master/ca.crt --signer-key=/var/lib/origin/openshift.local.config/master/ca.key --signer-serial=/var/lib/origin/openshift.local.config/master/ca.serial.txt --hostnames=kubernetes.default.svc,kubernetes.default.svc.cluster.local,localhost,openshift.default.svc.cluster.local,127.0.0.1,10.2.2.2,yourdomain.com,yourpublicIP
Hope this helps
Here is what I've tried (in an answer to better document my attempts)
1 -
systemctl stop origin
2 -
oadm ca create-server-cert --cert=/var/lib/origin/openshift.local.config/master/master.server.crt --key=/var/lib/origin/openshift.local.config/master/master.server.key --signer-cert=/var/lib/origin/openshift.local.config/master/ca.crt --signer-key=/var/lib/origin/openshift.local.config/master/ca.key --signer-serial=/var/lib/origin/openshift.local.config/master/ca.serial.txt --hostnames=kubernetes.default.svc,kubernetes.default.svc.cluster.local,localhost,openshift.default.svc.cluster.local,127.0.0.1,192.168.76.120
3 -
edit /var/lib/origin/openshift.local.config/master/master-config.yaml, replace all occurences of "10.2.2.2" with "192.168.76.120"
4 -
edit /etc/systemd/system/origin.service, replace "10.2.2.2" with "192.168.76.120"
5 -
systemctl daemon-reload
6 -
systemctl start origin
Following these steps, I get the following in the /var/log/messages:

Add bees.api.url=https\://api.cloudbees.com/api to ~/.bees/bees.config
After backing up ~/.bees and then running bees init and recreating my bees configuration directory I noticed the extra entry in bees.config.
I have an Eucalyptus-based cloud using Xen with 3 nodes. When I run a VM more than twice the number of physical machines in the xen cluster, the extra VMs never boot up, they always change state from pending to terminate, and the log file shows the node controller shutoff the extra VM after it check the instances number. When I manually shutdown some VM, then I can easily start up some VM exactly as the number I've shutdown.
The log shows this error:

Is this a limitation for CentOS 5.* and RedHat 5.? Is it fixed on CentOS 6.?

"Only 3 virtual network interfaces are supported in versions below 5.2. For 5.2 and above, 7 virtual network interfaces are supported."
I opened this topic in both CentOS and Eucalyptus forums without luck:

Thanks, Leandro
The error you are seeing seems related to disk not to network (Device 2049 (vbd) could not be connected. /etc/xen/scripts/block failed; error detected). I don't see that script on a CentOS 5.7 install I have here, so you may want to dig into that script to see if there is some obvious error.
The solution was to increase number of loop devices in CentOS 5, as detailed in the following link:

As the link is no longer valid, you have to go to archive.org or see this similar answer:
