Performance and Memory Optimization

Performance and Memory Optimization

During synchronization, data packets are loaded in to memory to process synchronization objects in parallel. The size of these data packets can be increased to speed up synchronization but this required more memory. By default, the size of the data packet is selected such that the ratio of memory to performance is balanced out. However, memory issues can still occur during synchronization. This often depends on the configuration of the system environment, the amount of data to synchronize and the exact synchronization configuration. You can control memory usage to avoid such problems. The degree of change is determined with the performance/memory factor.

The performance/memory factor can be set for each synchronization step separately because the amount of data varies from object to object. The first thing to do if a memory problem occurs during synchronization, is to find the affected synchronization step. Reduce the performance/memory factor for this synchronization step until you find the optimal balance between memory requirements and performance.

To adjust the performance/memory factor for a synchronization step

1. Edit the synchronization step properties.

   For more information, see How to Edit Synchronization Steps.

2. Select the Extended tab.
3. Use the slider to set the performance/memory factor.
   • Move the slider to the left to reduce memory usage. This reduces performance.

     - OR -

   • To increase performance, move the slider to the right. This requires more memory.
4. Click OK.

The performance/memory factor specifies the percentage with which the reload threshold, partition size and bulk level are applied to an object type.

Setting up Synchronization

Setting up Synchronization

Use the Synchronization EditorOne Identity Manager tool for configuring target system synchronization. to configure connections for different target system in One Identity Manager. Components of a synchronization configuration are used not only for synchronization but also for provisioning the data in this case. SynchronizationThe process of comparing data between One Identity Manager and a target system. Objects and their properties are compared by fixed rules. Synchronization results in the identical data situation in the target system and One Identity Manager database. can be configured so it can be used for connecting different target systems of the same target system type.

Creating a Synchronization Project

Creating a Synchronization Project

A synchronization project collects all the information required for synchronizing the One Identity Manager database with a target system. Connection data for target systems, schema types and properties, mapping and synchronization workflows all belong to this. Various synchronization projects can be created with a different scope for each target system.

Prerequisites

• A synchronization server is set up and declared in the One Identity Manager database.

There is an wizard to assist you with setting up a synchronization project. This wizard takes you all the steps you need to set up initial synchronization with a target system. The project wizard takes over the following tasks:

• Connecting to the Target SystemAn instance of a target system in which the employees managed by One Identity Manager have access to network resources. Example: An Active Directory domain X for target system type "Active Directory", a directory Y for target system type "LDAP", a client Z for target system type "SAP R/3".
• Connecting to the One Identity Manager database
• Defining synchronization behavior

  The configuration synchronization behavior can be based on a target system specific project templates. Project templates are supplied by One Identity Manager for certain target systems, The project wizard copies the project template data. This can be modified with the project wizard to suit the new synchronization project.

After saving the synchronization project, you can alter the synchronization configuration.

To complete synchronization configuration

1. Check the mappings, workflows, start up configuration and system connection that the wizard has added.
2. Assign a schedule to the start up configuration.
3. If you want to use the synchronization project to synchronize different target systems, specify variables and variable sets.
4. Activate the synchronization project. The synchronization cannot be started until these are resolved.
