When attachments are included in an email, the attachment
files are downloaded to a temporary directory on the IBM® Rational® ClearQuest® Client local computer.
The defined default location for the temporary directory is as
follows:
- Windows
- The value of the %TEMP% environment variable.
For example: C:\Documents and Settings\username\Local Settings\Temp
- The value of the %TMP% environment variable.
For example: C:\Windows\Temp
- UNIX
- The default tmp directory. For example: /tmp/ClearQuest/EmailPlus/Cache
You can customize the location of the temporary cache directory
on Windows, Linux, and UNIX platforms
by defining the
EMP_TEMPDIR system environment
variable. Set this environment variable to an absolute file path of
your choice. Your ClearQuest client
must have read/write access to this directory and have the ability
to create files within the directory. On Linux and UNIX systems
that multiple users access, you might need to define one
EMP_TEMPDIR variable
and create the directory with write permission for all users of that
system. Alternatively, you might have to define
EMP_TEMPDIR environment
variables and directories for each individual user, if you are concerned
about file system security issues.
Note: For best results, use the EMP_TEMPDIR system
environment variable on ClearQuest Web
servers if you plan to send attachments in EmailPlus notifications.
ClearQuest Client
temporary cache directory housekeeping
Many record attachments
are deleted after they have been included in an EmailPlus notification.
However, to improve performance, template attachments are cached for
the duration of a ClearQuest session
and might not be deleted. A good practice is to periodically remove
files from the temporary directory to prevent filesystem capacity
issues. This housekeeping could be done using a cron job on Linux and UNIX systems, or a scheduled task on Windows systems. Be careful when
deleting these files because some of the files might still be required
by open ClearQuest sessions.
Consider deleting cached attachment files only if they are older than
24 hours old.
