  • status: failed
  • Click Detail: Caused by: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: GC overhead limit exceeded
  • After HRIS Sync job will restart and run successfully


  • The job can fail to connect to database as a result of Memory Cache of Jboss Server being exceeded
  • Caused by: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: GC overhead limit exceeded


Hris sync jobs failed because of DC(data center) performance Memory Cache Issue and the Hris sync job will restart internally by operation team at the Database level

If issue occurred very often,

Normally the "Job Owner" of the Hris job will receive an e-mail notification when the job is completed and it will give the status of "Successful", "Failed", "Interrupted". Also, if you check the "Details" of the job, you might see an Exception in the Details.

Note: As a customer, you don't have access to Provisioning. To complete tasks in Provisioning, contact your implementation partner.

 FAQ - Additional Information

Q) Are there any Integrations (via API) setup to manipulate Basic User Data (UDF)?

A) Same as with Basic User Imports, if you have Integrations setup to feed data from a 3rd party system into Basic User Data, there is potential that you are overwriting the data synchronized by HRIS Sync.

Please refer to article 2080813 - HRIS Sync: Import & API upsert considerations - Employee Central - for more information and Here

EC Data Import or User Data Changes Through API

If there is at least one recurring HRIS Sync job configured in your company instance, an HRIS Element (Employee Central data) import triggers an HRIS Sync job run. This import of data can be from the UI or through API. Only one HRIS sync job can run at a time.
