Check for Stranded Audio Links
Introduction
Audio files used in conjunction with the EAS system are defined with an expiration
time and date. Sometimes, when the MMM Server process of the DNCS is bounced
before an audio file expires, a link to that audio file remains on the DNCS. This
audio link is said to be “stranded.” After an upgrade, engineers need to examine the
dncsLog file for the presence of a stranded audio link, and then delete that link, if
necessary.
Checking for Stranded Audio Links
Follow these instructions to check the DNCS for a stranded audio link and then to
delete that stranded link if one is found.
1.
If necessary, open an xterm window on the DNCS.
2.
Type cd /var/log and then press Enter.
Result: The /var/log directory becomes the working directory.
Result: The /var/log directory becomes the working directory.
3.
Type grep -i aiff dncsLog and then press Enter.
Result: The system checks the dncsLog file for the presence of aiff.
Note: The file extension of audio files used by the MMM Server is aiff.
Result: The system checks the dncsLog file for the presence of aiff.
Note: The file extension of audio files used by the MMM Server is aiff.
4.
Did the grep operation from step 3 return a line similar to
[Date Time] dncs bfsServer BFSDir::_checkLinkedFiles() Error,
can’t find file /MMMAud/a1847750.aiff, marking as inaccessible?

If yes, go to Deleting the Stranded Audio Links, next in this section.

If no, go to Check the EAS Configuration, later in this chapter; you have
no stranded audio links.
