APPLIES TO: Oracle Database Cloud Schema Service - Version N/A and later Gen 1 Exadata Cloud at Customer (Oracle Exadata Database Cloud Machine) - Version N/A and later Oracle Cloud Infrastructure - Database Service - Version N/A and later Oracle Database Backup Service - Version N/A and later Oracle Database Cloud Exadata Service - Version N/A and later Information in this document applies to any platform.   GOAL This document is intended for the database and system administrators who wish to install Anti-virus Software on the Server running Oracle Database. This document will help you to identify the Oracle files which needs to be excluded from Anti-virus scanner. SOLUTION When an Anti-virus performs a scan on a file it holds a lock on it. This lock interrupts the normal functioning of the database. To prevent any disaster situation such as database crash/hang, we recommend the following files to be excluded from online anti-virus scanning. Oracle datafiles Control files Redo-log files Archived redo-log files if database is in archive log mode Files with extension '.ora' Password file File in ADR directory Oracle Software directories (including Oracle_HOME and Oracle base) /dev/shm on Linux platform You can also contact your anti-virus vendor to know more about the details of the scanning mechanism of the particular anti-virus software and for any additional Oracle files that has to be excluded from the scanner. Sometimes excluding only these files is not sufficient, so exclude the entire folder/directory of oracle database files. NOTE: Anti-virus software consumes OS resources heavily. Installing anti-virus software along with Oracle database may impact the database performance.
