Solution 2257659.1 : Performance Intelligence Center (PIC) - Empty Exported Files From "Browser Export" application Due to Space Issues on Distant FTP Server

Applies to:

Oracle Communications Performance Intelligence Center (PIC) Software - Version 4.1 and later
Information in this document applies to any platform.

Symptoms

Exported files (from "Browser Export" application) are empty on the distant FTP server (having as size 0 Bytes).

Cause

Distant FTP server is having some space issues and this explains why exported files are empty. xDRs are properly exported to the temporary file created on the NSP server. However, the file transfer to the distant FTP server is failing with the below error logged in "/var/log/nsp/weblogic/nsp/application*.log" NSP files:

Above observation is being confirmed by manual FTP transfer from the NSP server to the distant FTP server. In the below example, "application.log" file (having a size of 1MB on the NSP server) is transferred to the distant FTP server. You can see later from the "ls" command output that the file size on the FTP server is 0 Byte:

[root@NSP]# cd /var/log/nsp/weblogic/nsp/
[root@MONNSP nsp]# ftp 1.1.1.1

Solution

Contact FTP server administrator (Generally Customer) and ask to do appropriate actions in order to free space on distant FTP server.
