                                                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-noti

                                                This is my 100th post on my blog and in this post, I will list down interview questions on OIM. This post will always be work in progress as I keep appending this list with more and more questions. Please find the list of questions below :-) What are the new features in PS3 ? What are the differences between PS2 and PS3 ? How do you identify rogue account creation in target system ? What is the high level architecture of OIM 11g ? List out difference between OIM 9.1 and 11g and possibly 11gR2 What are the new features in 11gR2 PS2 , PS3 How do you save multi-valued attribute in process form and how the linking happens between process form & child form ,   1 child form per multi valued attribute Can we still use entity adapters in OIM 11g What is pluginservice in oim 11g/  What is the orchestration service in oim 11g. what is the difference between entity match found  and process match found ? what are service accounts in oim ? why remote manager is used ? What is a c

                                                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
