System Maintenance

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:
