Solution 1934564.1 : Measurements For Deleted Associations Still Showing In Measurement Files

Applies to:

Oracle Communications EAGLE (Software) - Version EAGLE 45.0 to EAGLE 46.0 [Release EAGLE 45.0 to EAGLE 46.0]
Information in this document applies to any platform.

Symptoms

1. We have noticed that in the measurement files, the statistics for deleted associations are still showing:

"STATUS","ASSOC","ECASNEST","DURASNEST","DATCHKSN","RTXCHNKS","DATCHKRC","SCPKTSNT","SCPKTRCV","SCOCTSNT","SCOCTRCV","CNTLCHKS","ORDCHKSN","CNTLCHKR","ORDCHKRC","GAPACKSR","ASOCABTD","ASOCSHTD","PEERFAIL","ASMAXRTO"
"I","xxxpoc",0,900,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
"N","xxxtitantst", , , , , , , , , , , , , , , , , ,
"N","xxxsmsx1", , , , , , , , , , , , , , , , , ,
"N","xxxsmsx2", , , , , , , , , , , , , , , , , ,
"I","xxxwcssim3",0,0,3551,0,3649,6379,6523,704392,674960,4089,3551,4017,3649,0,0,0,0,518

2. Additionally, the information for the other associations is being marked as "I" instead of "K".

Cause

1. Title: Associations deleted from system in past still appear in the comp-sctpasoc Comma Separated Values (CSV) reports

PR: 231613 (BUG 19106690)

Each 30 minutes interval, Stream Control Transmission Protocol (SCTP) associations measurements are written to disk using an index.

- This index is not sequential so the entries are scattered throughout the table, anywhere from 0 to the total number of valid SCTP associations entities.
- The set of measurements that were collected 24 hours ago still exists in the meas table (on the disk).

The reporting algorithm simply searches for non-zero timestamps from 0 to the total number of valid SCTP associations entities.

- If the association is still provisioned, the new data will overwrite the old data because the index will remain the same.
- If an entry has been deleted, nothing will be written at that index, leaving the old entry intact.

Even though the timestamp has expired, it is non-zero and thus picked up by the reporting function.

2. The associations measurement reports with E5-OAM Integrated Measurements shows Incomplete (I) status:

PR: 234507 (BUG 19110446)

Cause:
Counter is not updated to 900 seconds (15 minutes interval) reporting the measurement as incomplete (I).

Solution

This two issues are fixed on EAGLE R46.0 which is Generally Available (GA).
