Special Topics: Best Practices Maintenance, backup, and database tuning

Maintenance, backup, and database tuning

 Perform regular manual backups of your database using the Backup feature in the

Manager software. Your configuration tables are saved by default once a week on

Saturday. See Backup on page 15, for more information on backup best practices.

 Database backups are cumulative and the size of a backup file can become quite

large. Perform regular file maintenance to prevent disk space issues.

 Archive your alerts and packet logs regularly, using the Alert and Packet Log Archival

feature. McAfee recommends that you archive your alert data monthly, and that you

discard alert and packet log information from your database every 90 days to

manage your database size. Note that there is currently a 4GB size limitation for a

single archive file.

 Online database tuning operation causes the creation of temporary alert and packet

log tables; if you are using an agent that queries the database, your agent may

attempt to interact with these tables during tuning. There is a remote chance that

during the transition to the temporary tables, the SQL query will result in an error. If

a SQL query error occurs, simply retry the query. Further information on the impact

of online database tuning of the ISM database will be sent to the third-party vendors

that are directly accessing this database. If you have any specific questions, contact

Technical Support. Also note that there is no change in database SQL query behavior

if online database tuning is disabled.

 McAfee recommends that you make a regular practice of defragmenting the disk of

the Manager server, as disk fragmentation can lead to database inefficiency.

 When scheduling certain Manager actions (backups, file maintenance, archivals,

database tuning), set a time for each that is unique and is a minimum of an hour

after/before other scheduled actions. Do not run scheduled actions concurrently.

 McAfee recommends that you tune your database at regular intervals using the

online tuning tools available beginning with release 2.1.1.

 Refer to the Oracle9i Deployment Guide document (included on the product CD) for

information on Oracle hardware requirements, Oracle database setup, IntruShield

Manager installation for use with a remote Oracle database, and for information on

proper database tuning.

 If you are using an Oracle database, McAfee strongly recommends that you employ

an Oracle DBA to maintain your database.

Note

See Chapter 4 of the Manager Administrator’s Guide for more details on port

clustering.

Warn ing

A database left untuned can, over time, lead to data corruption.

Tip

See Chapter 6 and Appendix of the Manager Administrator’s Guide for more

information on tuning your database.
