Site Preferences dialog box
The SMAT file history settings are stored in the siteInfo file. This setting is configured on the tab. On this tab, you can enable the SMAT History feature.
The Delete the oldest SMAT inbound/outbound history file when history file's number for a thread exceeds number files and Delete the oldest SMAT history file when history file's total size for a process exceeds number KB options are used to maintain the SMAT history files. When is selected, the cycled SMAT files are saved. Otherwise, the earlier files are deleted after the limitations of the file number or the disk size are reached.
is the command to compress the backed-up SMAT files to save disk space.
- If there are more than one file to compress, then each file is compressed individually.
- If no command is configured, then the cycling files are not archived.
By default it is set to NULL and compression is disabled. The gzip and compress commands are supported.
SMAT cycles message, index, and .ecd files with these naming conventions:
- filename.old.msg
- filename.old.idx
- filename.old.ecd
To avoid "clobbering", unintentionally overwriting, earlier cycled files,
the SmatHistory
feature cycles the files with a time
stamp. This feature is similar to the engine’s LogHistory
feature.
When this feature is enabled, it cycles the old files to the process directory/SmatHistory directory instead of straight to the process directory.
The cycled files have these file names:
- filename.YYYY-MM-DD_HH-mm-SS.msg
- filename.YYYY-MM-DD_HH-mm-SS.idx
- filename.YYYY-MM-DD_HH-mm-SS.ecd
In these files:
-
YYYY
is the year -
MM
is the month -
HH
is the hour -
mm
is the minute -
SS
is the second
For example, files named conn_1.msg and conn_1.idx are cycled 42 seconds after 2:03 PM on January 21, 2009. The message and index file names are:
conn_1.20090121140342.msg
conn_1.20090121140342.idx
They would then be placed in the SmatHistory directory.
Differences with earlier versions
Previous versions would have named the above files as:
- conn_1.old.msg
- conn_1.old.idx
When the
feature is enabled, the files are cycled with the SmatHistory convention, begun in version 6.0 and later.When the .old convention of earlier versions.
feature is disabled, the files are cycled with theSee hcismatconvert.
