data_engine keeps stopping

Issue/Introduction

• data_engine probe periodically stops and in data_engine.log I see

ADO_Database::ExecuteSP com error for [Microsoft OLE DB Provider for SQL Server] The transaction log for database 'CA_UIM' is full due to 'ACTIVE_BACKUP_OR_RESTORE'.

 

Cause

• SQL has run out of space for transaction log and therefore the data_engine cannot write any data to db.

Environment

Release:
Component: UIMDEG

Resolution

• Provide more space either by increasing size of transaction log or by truncating it.
• Should also check that autogrow is not at default of 1MB for data files and 10% for transaction log, Increase both to a fixed MB value (e.g. 100MB) to ensure that the DB can always keep up with demand
