We have a Jenkins cluster running with master node and 6 child nodes(4 windows child nodes, 2 Linux child nodes).
Recently the IP of the master node has changed due to network updates.
The Linux child node are successful in connecting with the master node whereas the windows child nodes are not able to connect.
The client jar file after change of master node IP for windows fails to connect with the to master node from child node.
Does anyone know how to configure the system when Jenkins master node IP has changed with windows child nodes?
Jenkins version is 2.9
Tried changing configs for windows child nodes.
Generated Client JAR files after change of master node IP.
I am trying to create an HA environment with PostgresSQL server. I have two nodes with Windows Server 2016 installed on it. Due to client limitations we cannot use Linux servers and I am tasked with creating an HA environment for Postgres SQL.
Can someone please guide me as how to go about creating it.
Two of my drives crashed on the Ambari Server node so I have to re-migrate my Ambari Cluster. No real data was lost (due to a different backup strategy) but the configuration files of the node, including Ambari Server configuration, are gone.
Because two drives crashed, I can not access any files from that node anymore (RAID 5).
I am now in the process of reinstalling the Ambari Server on the same node and would like to have my agents seamlessly reconnect to the "new" Ambari Server.
Is there a way to migrate the existing Cluster settings to the Ambari Server? I am thinking of Cluster settings that were distributed to the agents or similar.
If there is no such way to migrate the cluster, how would I go and install the Ambari Server? Do a fresh install and setup everything again? Will the Ambari agents be able to connect to the "new" Cluster without problems? Note that the Ambari Server will run on the same hostname/ip.
I am trying to add a new Spark node to an existing DSE 4.8.4 cluster running on EC2. I use following settings:
AMI = ami-50520e27
AMI username = ubuntu
Use OpsCenter specific security group
Key file using by the existing cluster
The machine spins up, but in OpsCenter > Activities > Add Nodes there is a message saying "Determining SSH fingerprints" which stays there forever.
I have a multi tier application that want to use a RAC to improve the availability of the server.
What we have now is, the client side sending a transaction data to the server side through a webservice. At client level, we need to specify the url address (IP address) as a path to send a data.
As for now, there are 2 oracle instance installed as a RAC at a server.
1. 133.38.52.101
2. 133.38.52.102
Both of the server are connect to same Oracle Database (SAN storage).
Let say, the client side is pointing to .101. Suddenly the .101 machine is down, how can I possible to use the .102 without changing the point URL at the client side. Is there any configuration can be done at RAC or Windows Server 2008 for this type of problem?
Use a load balancer between client machine and application server machines.
Use Oracle's transparent application failover functionality in OCI to achieve redundancy and load balancing between application server machines and RAC instances. DML transactions will be rolled back but selects will be transparently failed over.
