On ITO Managed Nodes
You should periodically backup, and then erase, local ITO logfiles (and
their backups). ITO uses 90% of the specified log directory size for local
message logging and 10% for error/warning logging. ITO also uses an
automatic backup mechanism for the logfiles (four on UNIX systems,
nine on MPE/iX). For example, the configured size of a UNIX log
directory is 10 MB and is allocated in the following way:
❏ 9 MB for local message logging.
Since there are four logfiles, if the opcmsglg file size is greater than
9/4 MB, ITO performs the following tasks:
• if it exists, move opcmsgl2 to opcmsgl3
• if it exists, move opcmsgl1 to opcmsgl2
• move opcmsglg to opcmsgl1
❏ 1 MB for local error/warning message logging.
Since there are four logfiles, if the opcerror file size is greater than
1/4 MB, ITO performs the following tasks:
• if it exists, move opcerro2 to opcerro3
• if it exists, move opcerro1 to opcerro2
• move opcerror to opcerro1
Unless there is no alternative, or if there are too many unprocessed and
old messages, do not clean up the directories listed in Table 10-12 on
page 474: these directories contain important runtime data:
