3 Data LoadThis chapter provides procedures for initial load of data into Oracle Role Manager. The data loader can be used to load new objects or update existing objects in the system. For information about implementing special processing as part of a load procedure, contact your Oracle Consulting Services representative.This chapter assumes you have deployed the standard data model provided with Oracle Role Manager or a custom model built on the standard model. It also assumes that you understand the business requirements associated with the data that must be loaded into Oracle Role Manager.It contains the following topics:. Note:Oracle does not recommend you to use Microsoft Excel to edit the CSV file, because it inserts extra quotes when you insert double quotes in the file.Load proceduresLoad procedures contain the object creation and relationship creation procedures that map to the BL definitions. Load procedures are a clean representation of the default load operations, uncluttered by the system-level details contained in the BL definitions.Business logic (BL) definitionsThe BL definitions contain detailed procedures representing the default loadable objects, attributes, and relationships and the XML mapping to BL Plug-ins for business operations called by the loader request.File parsing scriptsThese scripts contain mappings to load procedures and the load sequence of input parameters (attributes) within the load operation relative to object type. This commonly includes only a subset of the object's attributes into which to load data.Load requestThe load request defines which load procedures should run as part of the data load.
This file also specifies the order for loading objects in the required sequence.All data loaded into Oracle Role Manager enters through the business logic layer to be imported correctly. This is enforced by having the object definitions in the load procedures match those in the BL definition files. For example, the BL definition for the person object contains the same or superset of attribute definitions as those included in the createPerson load procedure.If you have data to load into custom object definitions or custom attributes, you will need to add new business logic and load procedures. 3.2 Data Load ScenariosBefore loading data, there are three questions you should ask to help identify the approach to take in loading your data:.Does the deployed data model contain all the object types and attributes you want to load?.Do the standard load procedures for each of your object types contain all of the operations you need?.Do the load operations in file parsing scripts for each of your object types contain all of the attributes you want to load?The following three examples describe the possible business scenarios around initial data loads into Oracle Role Manager. Choose the most suitable scenario, which will identify the steps that you will need to follow.
(Refer to for information about the Oracle Role Manager standard defaults.)For each of these examples, you can refer to to help visualize the load process flow for your deployment of Oracle Role Manager. Example 3-1 The data you want to load already maps to the standard data model and standard load procedures.The standard data model and the file parser scripts must contain all the object types and attributes that you want to load and there are no model changes required to load your data set.Even if your business model requires data model extensions, because you don't need to load data into the extended schema, you can still use the sample scripts.This example requires the following steps:.Create load request.Prepare data files.Bundle and upload data with request.
Example 3-2 The standard data model supports the data you want to load, but the attributes in file parser load scripts aren't what you want.In other words, the mismatch is only in the way the file parser script orders or maps the subset of attributes for a particular of multiple object types. For example, if the person file parser script maps six attributes for person data and you want to load twelve attributes.As in, if the data model has been extended but the data you want to load is not part of the custom model, fewer components are involved in the load process.This example requires the following steps:.Create new file parser scripts from existing sample scripts.Bundle and deploy new configuration.Create load request.Prepare data files.Bundle and upload data with request. Example 3-3 The data to load must go into a custom model.Whether your data model extensions into which you want to load data are an added attribute or a new object type, loading data into a custom model requires supporting business logic and new process definitions.This example assumes the data model has already been extended and requires the following steps:.Create BL definitions.Create load procedures.Create file parser scripts.Bundle and deploy new configuration.Create load request.Prepare data files.Bundle and upload data with request.
Example 3-4 Query that returns attributes for Role Manager PERSON objects.select 'A000001' as id,'John' as firstname,'Smith' as lastname,'John Smith' as displayname,'active' as statusfrom dual.Define a data source that your application server can use to execute queries. The procedure for doing this varies from one application server to the other.Create a load script that will execute your query and return query results to the appropriate Role Manager task.For example a load script named persondbscript.xml creates a procedure named loadPersonsFromDB. The version of the script and its dependencies are declared. In this case the business logic dependency was copied from another load script. If you go through several iterations of the script while debugging, it is important to increment the version number whenever the script is changed.
When deploying the script, the new version number signals Role Manager that any previous versions are obsolete. If the version number is not incremented, then the deploy task exits without deploying the new script. Example 3-5 Load Data
You can do this by creating a car file that contains just the script(s) that loads the external data. First put the load script in a directory with the path name that loader expects (config/oracle.iam.rm.loader). A test directory (testdbload) was used to isolate this experiment from the Role Manager installation:testdbloadconfigoracle.iam.rm.loaderTo create the car file:.Change to the parent of the config directory (testdbload). Use zip to create the car file:zip -f testdbload.car config.Copy testdbload.car to the The ordering mode ('trusted-sequential') was copied from another load script. Example 3-6 Load Request Using this feature, you can load DAR files automatically. The following is the command used to load the DAR file: load.bat serverurl darfile ormusernameAn example for this command is: load.bat./data/mypeople.dar adminWhen you execute this command, the password for the administrator user is prompted. If you are loading the DAR file automatically, you can avoid the password prompt using the following command: load.bat./data/mypeople.dar admin/admin123Running the automated load process is a security issue. This is because, users with access to the computer running the tool can see the administrator's password in the process list. To prevent the users to view the administrator's password, Oracle recommends you to create a custom system identity and grant them a custom system role that has been granted the absolute minimum system privileges, necessary to load the data that they will be loading. The following example illustrates this scenario. Example 3-7 Loading Data With Custom System IdentityAssume that the command-line tool is only used for loading people using a reconciliation process. The system identity used for the tool must be able to run the person reconciliation business operation. To enable this and to limit the impact of this user's credentials being exposed, perform the following:.Create a new permission called 'reconcile' and associate it with the person object type.Create a new business operation for the person attribute reconciliation and assign 'reconcile' privilege on person.Create a new loader script that invokes the new business operation.Create a new system role and associate it with the new 'reconcile person' privilege.Create a new system identity and grant the new system role to it. For more information about system identity, refer to.The newly created system identity can now only be used to load person details to be reconciled. 3.4 Understanding the Standard Model (Default)If you're not sure how to determine which process your load will require, you can analyze the default loader components provided in Oracle Role Manager. This section describes these components in more detail and shows you where to find the scripts that you will either use by default or use as starting places, should you need to create new ones.It may be useful to familiarize yourself with the standard data model along with any schema extensions that are planned or already deployed.In this section:. 3.4.1 Sample Loader Scripts and Standard Model DescriptionTo view the sample loader scripts and procedures, will need to extract them from an archive file. 3.4.2 Default Loader Procedures (Standard Model)The default loader procedures, in a single XML file ( procedures.xml), provide a convenient view into the standard data model as it relates to the default load operations. This file maps procedures to the business logic operations that can be called by load requests.The load procedures contain all the predefined, default load operations available for use in load requests (see ) that can be used to create objects and the relationships between those objects. The load procedures also contain the superset of all possible attributes to load per object type. Example 3-8 Load Procedure (addToReportingHierarchy) The organization's name can be no longer than 256 characters.The parent's name can be no longer than 256 characters. Example 3-9 Plug-in Configuration (addToReportingHierarchy) In the preceding example, the plug-in ID is addtohierarchy and the configuration specifies the hierarchy type and the relationship paths. This allows that the Java plug-in class that handles this operation can be used for adding any object to any hierarchy, if it's supported by the schema. Example 3-10 File Parser (reportingscript) The binary must be provided. 3.5 Configuring Data Upload SizeYou can upload a DAR file to load data of maximum size one byte into the system. If you try to load data larger than this maximum upload size, you get an error message. You can configure the maximum data upload size to a higher or lower value than the default.For WebLogic ServerTo configure the data upload size for WebLogic server:.Go to Environment, Servers, ORM Server.On the Configuration tab, click the Server Start subtab.In the Arguments field, append the following argument to the new value. 3.6 Preparing Data FilesThe data files that you bundle with the load request must match the file names specified in the load request.Data files, normally text files in comma-separated format, contain actual data to load into Oracle Role Manager. Data files can use any character as a delimiter if it's set as the token-separator attribute in the script. The order of data, separated by the delimiter (with no spaces) must match the order of the input parameters in the respective file parsing script.It is recommended that you separate the data files by type of entity and relationship to have enough flexibility to load them in the correct sequence.To prepare your data files, bundle them with the load request as a DAR (data archive) file. 3.7 Running the Data LoaderInitiating the load process involves several steps to prepare the archive files expected by the loader. In addition, the Oracle Role Manager server must be running on the application server. 3.8 Abandoned Transaction CleanupAbandoned transactions are those pending transactions which have seen no activity in a configurable time-to-live period. The transactions are abandoned either because of a network problem between Role Manager client and server or the user of Role Manager navigates away from the transaction page without completing the transaction. Role Manager uses a configurable scheduled task to cleanup such abandoned transactions. The following factors are considered to cleanup the abandoned transactions:.Any pending transaction that has no activity within the time-to-live window is eligible for cleanup. However, the actual cleanup only occurs when the scheduled task for cleanup is run.An excessively short time-to-live window will interfere with normal user activities. Therefore Oracle recommends a time-to-live value of at least 1 hour.You can consider these two factors to configure the scheduled task. The default time at which the scheduled task is set to run is 1 a.m. And time-to-live value is 1 hour. These values can be set by unpacking the configurations.car file and editing the oracle.iam.rm.timer.abandonedTransactionCleanupTimer.xml file. The following is the default configuration file: oracle.iam.rm.bizxact.impl.AbandonedTransactionCleanupFactoryAbandonedTransactionCleanupJobTransactionGrouptimeToLive60 true0 0 1.? In the Project Settings, select the Signing & Capabilities tab. Make sure that “Automatically manage signing” is selected, and specify your development team.Click the + Capability button to open the Add Capability editor. In the search bar, type iCloud to filter the list, and choose the iCloud capability.An iCloud section appears on your app’s Signing & Capabilities page. Under Services, select the checkbox to enable CloudKit. Under Containers, leave the selection as “Use default container.”Selecting the CloudKit service enables your app to use CloudKit, and adds the push notifications capability. Push notifications allow CloudKit to notify your app when remote data has changed.Xcode attempts to register your app’s bundle identifier and manage provisioning profiles. For more information about working with CloudKit containers and setting up profiles, see.Finally, add the Background Modes capability, and select the “Remote notifications” checkbox.Because remote notifications happen silently in the background, user approval isn’t required and no dialog displays to the user. Update an Existing Xcode Project. You can add configurations in your data model to separate entities into discrete stores. This separation enables you to designate a subset of the data to store in the cloud, while keeping other data local to the device.Add a configuration to your project’s.xcdatamodeld file by selecting Editor Add Configuration, and drag and drop each entity into a configuration.For each configuration that should synchronize to CloudKit, select the configuration. In the data model editor, select the “Used with CloudKit” checkbox.When working with a single store, the persistent CloudKit container matches the first store description with the first CloudKit container identifier in the entitlements.When working with multiple stores, create an instance of for each store you wish to use with CloudKit. Use it to set the on the relevant store description.For example, the following code creates two store descriptions: one for the “Local” configuration, and one for the “Cloud” configuration. It then sets the cloud store description’s to match the store with its CloudKit container. Finally, it updates the container’s list of persistent store descriptions to include all local and cloud-backed store descriptions, and loads both stores.
