In our organization, we’ve undertaken the task of upgrading both SOA and OSB from version 12.2.1.3 to 12.2.1.4. This involves an out-of-place migration approach, wherein we create a new environment and switch traffic during the cutover. As you know, this process typically requires several days we opt for manual provisioing. Continue Reading

Rabbitmq Connection Error: javax.net.ssl.SSLHandshakeException: Invalid ECDH ServerKeyExchange signature
We have a 7 node test rabbitmq cluster. One of the rabbitmq users reported that they were getting “javax.net.ssl.SSLHandshakeException: Invalid ECDH ServerKeyExchange signature” error while connecting to Rabbitmq. We checked logs and also checked application up time. Rabbitmq servers hadn’t been restarted for the past 25 days. Also, we didn’t Continue Reading
SOA Suite 12.2.1.4 installation: Got exception when auto configuring the schema component(s) with data obtained from shadow table
We planned to do out of place upgrade from soa suite 12.2.1.3 to 12.2.1.4. As part of this, we planned to automate end to end provisioning. While executing domain configuration using ansible and python scripts, we got following error in domain creation step. Got exception when auto configuring the schema Continue Reading
Not able to start Rabbitmq Cluster: Cannot declare a queue ‘~s’ on node ‘~s’: ~255p
We have 7 node rabbitmq cluster and we are using sharding queues. We have shutdown all non prod rabbitmq nodes as part of VM patching. As it was non prod, we thought of shutting down all together instead of rolling patching. We couldn’t start the any of the rabbitmq post Continue Reading
Telegraf agent not able to monitor zookeeper
We use VMWare Wavefront for monitoring and visualization. We use telegraf agent as metrics collector. As part of Kafka monitoring, we have created alerts for Zookeeper availability. It was working fine initially but stopped working after a Kafka upgrade. We checked telegraf agent and zookeeper logs but could not find Continue Reading
Monitoring Weblogic, SOA, OSB using Prometheus and Grafana
In the previous blog post, we discussed about how to monitor weblogic based applications including SOA and OSB using Vmware Wavefront. In this blog post, let us explore open source alternative with Prometheus and Grafana. We will use Oracle Weblogic Monitoring Exporter in place of jolokia agent to export metric Continue Reading
Weblogic, SOA and OSB monitoring using Wavefront
Traditionally sysadmins used bash, WLST/Jython scripts to monitor weblogic based applications including Oracle SOA Suite and Oracle Service Bus. There are few disadvantages with this approach: With the advent of modern monitoring tools like Prometheus and Grafana, above challenges are addressed. We can setup beautiful graphs and dashboards quickly and Continue Reading
Not able to see Oracle SOA composite instances in em console
We recently built a new Oracle SOA suite environment with version 12.2.1.3. A particular service which is exposed through Gateway was throwing 401 Unauthorized error. There were no instances for this service in em console. So, we initially thought that issue might be with Gateway and analysis was directed towards Continue Reading
Monitoring Datasources in Weblogic/SOA/OSB
Datasource monitoring is one of the key monitoring topics in weblogic based applications. We have been using simple WLST script to alert us when a datasource is not working properly. Most of the times, root cause will be a intermittent network/DB issue. To recover from the issue, we will reset/restart Continue Reading
Monitoring Boomi Molecules
We use Boomi extensively for integrations. We have been monitoring Boomi based on existence of Boomi process on VM. This is not capturing all scenarios especially when Boomi process is hung or has cluster issues. To cover monitoring comprehensively, we developed new script based on Boomi Official Documentation recommendations. This Continue Reading
