Memory Configuration Considerations

If your use of Composer includes scheduling reports, you may need to update this memory setting. The default memory configuration is suitable for handling up to 10 concurrent reports (different reports scheduled for the same time). If you need to schedule more concurrent reports, increase the memory allocation to about one gigabyte (1GB) more for every 15 concurrent reports. See Configure Memory Settings.

Thread Count Considerations

If your use of Composer includes scheduling reports, update the screenshot microservice pool.thread.size setting so it is greater than the number of concurrent reports (see screenshot-service.properties Properties). This setting controls the thread count for screenshot microservice requests.

Obtain the Software

Before you can install the screenshot microservice, contact Composer Technical Support to obtain a download link for the screenshot microservice installation software. Be sure you specify the operating system you are using so the appropriate software is provided.
