Database |
On the Database tab, you can configure a DBMS required for Dr.Web Server operation.
To specify parameters of operating with the database 1.In the Number of connections field, specify the maximal number of connections of the Server with database. It is recommended to change default value only after consultation with the technical support. 2.Set the Automatically purge the database after maintenance procedures flag to automatically perform the delayed purging of the database after its initialization, upgrade and import. If the flag is cleared, automatic purge is not performed. In this case, it is recommended to configure the Purge database task in the Server schedule or purge database manually in the Database Management section. To perform the automatic purging, the hidden task is created in the Server schedule. The task is launched at nearest night after the named maintenance procedures, at 01:17 by local time of the Server. The task is executed only if the Server schedule does not contain another Purge database task within the next 24 hours relative to the named maintenance procedures. 3.Select the type of database in the Database drop-down list: •MySQL—external DB, •ODBC—to use external DB via the ODBC connection,
•Oracle—external DB for all platforms except FreeBSD,
•PostgreSQL—external DB, •SQLite3—embedded DB (a component of Dr.Web Server). 4.Specify requirement settings for an embedded DB operation: •If necessary, specify the full path to the database file into the File name field. •Specify the DB cache size. •Specify the cache size of precompiled sql operators. •In the Memory mapped file size (B) field, specify the maximum number of bytes of the DB file. •In the Image integrity verification drop-down list, select the verification mode of DB image integrity at Dr.Web Server startup. •Set the Restore corrupted image automatically flag to automatically restore corrupted DB image at Dr.Web Server startup. •Set the Enable WAL flag to enable Write-Ahead Logging. If the Enable WAL flag is set, you can also configure additional parameters: ▫In the Maximal number of "dirty" pages field, specify the maximal number of "dirty" pages on reaching of which pages will been written on the disk. ▫In the Maximal delay of pages writing (sec.) field, specify the maximal time to delay writing the pages on the disk (in seconds). • Specify the flush mode. 5.Click Save to apply specified settings. The parameters of an external DB are described in detail in the Appendices document in Appendix B. The Description of the DBMS Settings. The Parameters of the DBMS Driver.
Using an embedded DBMS is selected by default. This mode considerably increases the load on the Server. It is recommended to use an external DBMS in large anti-virus networks. Changing the type of the DBMS is described in the Appendices, document, in the Changing the Type of the DBMS for Dr.Web Enterprise Security Suite section.
