Sun Identity Manager 8.1 System Administrator's Guide

Data Classes

You can roughly divide Identity Manager data into a number of classes that exhibit similar properties with respect to access patterns, cardinality, lifetime, volatility, and so forth. Each of the following classes corresponds to a set of tables in the repository:

User Data

User data consists of user objects.

You can expect this data to grow quite large because there is an object for each managed identity. After an initial population phase, you can expect a proportionally small number of creates because the majority of operations will be updates to existing objects.

User objects are generally long-lived and they are removed at a relatively low rate.

User data is stored in USEROBJ, USERATTR, and USERCHANGE tables.

Role Data

Role data consists of Role objects, including Roles subtypes such as Business Roles, IT Roles, Applications, and Assets.

Role data is similar to organization data, and these objects are relatively static after a customer deploys Identity Manager.

Note –

An exception to the preceding statement is a deployment that is integrated with an external source containing an authoritative set of roles. One integration style might be to feed role changes into Identity Manager, which causes Identity Manager Role data to be more volatile.

Generally, the number of role objects is small when compared to the number of identity objects such as users (assuming that multiple users share each role), but this depends on how each enterprise defines its roles.

Role data is stored in ROLEOBJ, ROLEATTR, and ROLECHANGE tables.

Account Data

Account data solely consists of account objects in the Account Index.

As with user data, account data can become rather large, with an object for each known resource account. Account objects are generally long-lived, removed at a relatively low rate, and after initial population, are created infrequently. Unless you frequently add or remove native accounts, or enable native change detection, account object modifications occur infrequently.

Identity Manager stores account data in ACCOUNT, ACCTATTR, and ACCTCHANGE tables.

Compliance Violation Data

Compliance Violation data contains violation records that indicate when the evaluation of an Audit Policy failed. These violation records exist until the same Audit Policy is evaluated against the same User and the policy passes. Violation records are created, modified, or deleted as part of an Audit Policy Scan or as part of an Access Review.

The number of violation records is proportional to the number of Audit Policies that are used in scans and the number of Users. An installation with 5000 users and 10 Audit Policies might have 500 violation records (5000 x 10 x 0.01), where the 0.01 multiplier depends on how strict the policies are and how user accounts are changed.

Identity Manager stores Compliance Violation records in OBJECT, ATTRIBUTE, and OBJCHANGE tables.

Entitlement Data

Entitlement data predominately consists of user entitlement objects, which are only created if you are doing compliance access reviews.

Entitlement records are created in large batches, modified slowly (days) after initial creation, and are then untouched. These records are deleted after an Access Review is deleted.

Identity Manager stores entitlement data in ENTITLE, ENTATTR, and ENTCHANGE tables.

Organization Data

Organization data consists of object group or organization objects.

Object group data is similar to configuration data, and this data is relatively static after being deployed. Generally, the number of objects is small (one for each defined organization) when compared to task objects or to identity objects such as users or accounts, however, the number can become large compared to other configuration objects.

Organization data is stored in ORG, ORGATTR, and ORGCHANGE tables.

Task Data

Task data consists of objects that are related to tasks and workflows, including state and result data.

The data contained in these tables is short-lived compared to other classes because objects are created, modified, and deleted at a high rate. The volume of data in this table is proportional to the amount of activity on the system.

Task data is stored in TASK, TASKATTR, and TASKCHANGE tables.

Configuration Data

Configuration data consists of objects related to Identity Manager system configuration, such as forms, roles, and rules.

Generally, configuration data is:

Identity Manager stores configuration data in ATTRIBUTE, OBJCHANGE, and OBJECT tables.

Export Queue Data

If you enable Data Exporting, some records are queued inside Identity Manager until the export task writes those records to the Data Warehouse. The number of records that are queued is a function of Data Exporting configuration and the export interval for all queued types.

The following data types are queued by default, and all other data types are not:

The number of records in these tables grows until the export task drains the queue. The current table size is visible through a JMXTM Bean.

Records added to this table are never modified. These records are written during other Identity Manager activities, such as reconciliation, provisioning, and workflow execution. When the Data Exporter export task runs, the task drains the table.

Identity Manager stores Export Queue data records in QUEUE, QATTR, and QCHANGE tables.

Log Data

Log data consists of audit and error log objects. Log data is write-once only, so you can create new audit and error log objects, but you cannot modify these objects.

Log data is long-lived and can potentially become very large because you can only purge log data by explicit request. Access to log data frequently relies on attributes that are stored in the object table instead of in the attribute table. Both the distribution of attribute values and queries against the log specifically depend on how you are using Identity Manager.

For example, the distribution of attribute values in the log tables depends on the following:

The pattern of queries against the log table also depends on which Identity Manager reports, which custom reports, or which external data mining queries a customer runs against the log table.

Identity Manager stores audit log records in LOG and LOGATTR tables, and error log records in SYSLOG and SLOGATTR tables. This data does not have corresponding change tables.
