Solution 2397073.1 : Diameter Signaling Router (DSR) : Export Directory Not Getting Cleaned Up After Transfer To Export Server

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 8.1.0 and later
Tekelec

Symptoms

Customer created three different Export server in SOAM GUI : Administration -> Remote Servers -> Data Export
On two of them, they are sending Measurement report files, and third one is used for backup and configuration files.

As per Requirements, Files need to get cleaned up from NO after successful transfer of files to External Remote Server. As of now, we are not seeing
files getting cleaned up and resulting in huge number of files piling up in filemgmt area.

Changes

Cause

Look for the following logs from the Active SOAM Server CLI :

• ls -ltr /var/TKLC/db/filemgmt/.outgoing
• iqt –pE RemoteServer

Under /var/TKLC/db/filemgmt/.outgoing directory, we do find multiple directories created for different Remote Server ID's.

When we looked into the contents of those directories they seems to be empty or with old files , indicating they are the stale directories , Alternatively, we can check the iqt -pE RemoteServer output and look for the Remote Server ID's (i.e. directory number) listed in /var/TKLC/db/filemgmt/.outgoing and those which are missing in iqt -pE RemoteServer can be assumed as stale directory.

It seems we are hitting the BUG 26329245

The issue described in the bug will appear in the following scenarios :
1. User configured a Remote Server in Active Server
2. Switchover happened and user deletes the configured Remote Server before Periodic Task could have spawned.
Above scenario will lead to the stale directories under /var/TKLC/db/filemgmt/.outgoing and will affect the clean up procedure Clean up of the Export folder under /var/TKLC/db/filemgmt area will be affected, this will lead to accummulation of these files over the time.

Solution

In order to fix the issue we need to remove the stale directories available in ls -ltr /var/TKLC/db/filemgmt/.outgoing.

Workaround:

1. Identify the NetworkElement to which the Server Belongs
2. From RemoteServer table get the Remote Server Id configured for that Network Element
iqt -zh -fServer_ID RemoteServer where "NeName='<NE NAME>'"
3. Do ls -ltr /var/TKLC/db/filemgmt/.outgoing. All the Directories will be listed, each directory will be the name of the Remote Server Id
4. Remove the Stale directories under /var/TKLC/db/filemgmt/.outgoing directory by comparing them against the remote Server Ids that are configured
in RemoteServer table
