Infrastructure at your Service
End of last Month I participated as presenter to the DOAG 2017. It was interesting to see the growing interest on the automatic deployment tools. I presented the way the Fusion Middleware cloning can be used with such automation tool to lower the time needed to install an environment. The Fusion Middleware cloning is based on a master installation where all patches, configuration, system components are installed and configured. Thus, a real time reduction when…
Some times it happens that we need to rename an existing fusion Middleware WebLogic domain. I was asked to do such on a Fusion Middleware Reports & Forms environment. I took some time to check how this can be done and did some testing to confirm it works as expected. The difficulty is not the WebLogic Domain itself as a WebLogic domain can be created quickly but it is time consuming if the complete configuration…
Most of the time when the Reports Server is configured with an Single Sign On Server, it uses the same external LDAP server as the Single Sign On Server. In our case, we used an Oracle Access Manager as Single Sign On and an Oracle Internet Directory as LDAP server. Of course the Fusion Middleware needs to be configured with the external LDAP server. This means an Oracle Internet Directory authenticator provider declared in the…
We installed a Fusion Middleware report and Forms 12.2.1.2.0 on a Linux Server. This was a single node Reports and Forms servers. After disabling the Non SSL Listen Port, we get below error in logs while starting the Managed Server with only SSL ports enabled. ####<Oct 27, 2017, 2:38:23,265 PM CEST> <Info> <Deployer> <host01.example.com> <WLS_FORMS> <[ACTIVE] ExecuteThread: ‘1’ for queue: ‘weblogic.kernel.Default (self-tuning)’> <<WLS Kernel>> <> <728708fe-00a1-4078-bb31-f12fb2c6beae-00000030> <1509107903265> <[severity-value: 64] [rid: 0] [partition-id: 0] [partition-name: DOMAIN]…
WebLogic 12.2.1 provides a new RESTful management interface with full accesses to all WebLogic Server resources. This interface offers an alternative to the WLST scripting or JMX developments for the management and the monitoring of WebLogic Domains. The following of this blog provides a few examples demonstrating the simplicity and the efficiency of the REST requests. WebLogic Server State When checking a WebLogic Server state, we are interested in the state and in the “ActivationTime”…
WebLogic 12.2.1 provides a new REST management interface with full accesses to all WebLogic Server resources. This new interface provides an alternative to the WLST scripting or JMX developments for management and monitoring of WebLogic Domains. This blog explains how the RESTful interface can be used to determine a WebLogic Domain configuration and display it’s the principals attributes. For this purpose, a Search RESTful call will be used. The RESTful URL to point to the…
Introduction In Nowadays web technologies a common defensive mechanism against Cross-Site Request Forgery (CSRF) attacks is to use a synchronizer token. This token might be unique for each request and thus it blocks us from using the recorded JMeter test session off the shelf. This blog will describe how this CSRF feature can be handled in JMeter. How to implement this feature The solution is to identify and extract the CSRF token from the response…
On a customer site, one of the users complained about being kicked out each time he wanted to create new documents in D2. This issue is happening in a default deployment of D2 and D2Config in a WebLogic Domain.We found out that the user sessions for D2Config and D2 are conflicting together. This issue occurs if D2Config and D2 applications are opened in the same browser using different TABs and if the user is navigating…
The Load Balancers do not provide the client IP address by default. The WebLogic HTTP log file (access_log) does not provide the client IP address but the Load Balancer one. This is sometimes a problem when diagnosing issues and the Single Sign On configuration does not provide the user name in the HTTP log either. In most of the cases, the Load Balancer can provides an additional header named “X-Forwarded-For” but it needs to be…
Introduction In one of my missions, I was requested to run performance and load tests on a ADF application running in a Oracle Fusion Middleware environment protected using Oracle Access Manager. For this task we decided to use Apache JMeter because it provides the control needed on the tests and uses multiple threads to emulate multiple users. It can be used to do distributed testing which uses multiple systems to do stress test. Additionally, the…
