OIA - OIM coexistence, Integration and Issues

-
In this post, I will talk about the coexisting OIA and OIA side by side and some of the options that I tried and it's eventual outcome.

Option 1
Deploy OIA on the same OIM managed server. Does not work.

Option 2
Create a separate managed server and deploy OIA. That did not work either

Option 3
Create a new domain within the same middleware home and deploy OIA in a server there. Unfortunately that also did not work.

Option 4
Deploy OIA on a fresh weblogic middleware home. Finally it worked.
All along it kept complaining about a context loader and some other issues which are difficult to debug.

To conclude OIA and OIM in the same domain  or same middleware home does not work.

There were issues that arise during integration, firstly with option 4 you will have to establish domain level trust between the 2 domains to fix the authentication issues.
Other fix is to set prefer-web-inf-classes to true in weblogic.xml in WEB-INF folder. Well this is not an integration per se but a general fix to load application libraries first and then the app server libraries. More to do with the class loading issue.

OIM 11g R2 PS2 : SOA Approval Workflow Sample

Image
In this post I am posting the sample code for a sample SOA approval workflow. Some of the features that this workflow addresses are Approval to Manager or Role Owners is dynamic based on the custom OIM system property "approval-condition". Value is set either "AND" or "OR". Manager or Role Owner can be set to be notified only with no approval required. In this case only email is sent to notify them but no approval is required from them. Custom OIM system property are created to address this.   manager-notify-only = TRUE or FALSE  TRUE = only notify the manager no approval request sent. FALSE = notify the manager and send an approval request.   roleowner-notify-only = TRUE or FALSE  TRUE = only notify the role owner no approval request sent. FALSE = notify the role owner and send an approval request. Third Level System Notification was required but it should be dynamic.  Custom OIM system property are created to address this sysadmin-...

OHS 12c (12.1.3) webgate deployment and configuration

-
In this post, I will cover the deployment and configuration of webgate 12c webgate. OHS 12c comes pre-bundled with a webgate so we don't have to separately download and install any webgate. If you have installed OHS then you have a webgate which you can configure to protect OHS. Also there is no gui screens involved as all configurations are done via command line tools. In the previous post i covered installation and configuration of OHS 12c. This post builds on top of that. Step 1 deploy webgate ./deployWebGateInstance.sh -w /OHS_12c_WEBSERVER_HOME/webserver/instances/instance1/config/fmwconfig/components/OHS/ohs1 -oh /OHS_12c_MW_HOME/ Copying files from WebGate Oracle Home to WebGate Instancedir Step 2 Config webgate export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/OHS_12c_MW_HOME/lib cd /OHS_12c_MW_HOME/webgate/ohs/tools/setup/InstallTools/ ./EditHttpConf -w /OHS_12c_WEBSERVER_HOME/webserver/instances/instance1/config/fmwconfig/components/OHS/ohs1 -oh /OHS_12c_MW_HO...
