Cisco TrafficDirector

Field Notice: Updating to TrafficDirector 5.2 Prevents Data Used by TrendReporter from Being Logged

September 1, 1998

Products Affected

TrafficDirector 5.2

Problem Description

After installing the Software Module Update (SMU) that updates TrafficDirector 5.1 to 5.2, the TrafficDirector application is unable to log data to the SQL database that is used by the TrendReporter application to generate reports based on data that is stored in the SQL database.


The TrafficDirector 5.2 SMU, when installed, changes the owner and permissions on the file $NSHOME/bin/dbchkd. This file is used to spawn dbsnapd processes for each device for which logging has been turned on in either the Shared or Custom property files.

Problem Symptoms

To verify this problem, perform the following steps:

  1. Change the directory to $NSHOME/bin (/opt/CSCOcwsi/bin).

  2. Enter ls -al dbchkd

The expected output is: -rwsr-x-r-x 1 root bin 2113536 dbchkd

After installing SMU, the output will be: -rwxr-xr-x 1 bin bin 2113536 dbchkd

If the above output is displayed, change the permissions on the dbchkd file.


Change the permissions on the dbchkd file so that it is owned by root. To do this, enter the following commands:

chmod 4755 dbchkd
chown root dbchkd

A patch is being developed and will be posted to CCO no later than Friday September 11, 1998. When the patch becomes available, it can be found at the following URL:
