Long MFile Compilation Time after Mass Rating Data Import (Doc ID 2117610.1)

Last updated on MARCH 21, 2016

Applies to:

Oracle Communications Network Charging and Control - Version 4.3.0 to 5.0.3 [Release 4.3 to 5.0]
Information in this document applies to any platform.

Symptoms

On all versions of Oracle Communications Network Charging and Control (NCC), after importing a large amount of rating information into Charging Control Services (CCS), the compilation of new Memory Files (MFiles) by the ccsMFileCompiler starts taking an unacceptably long time on the Voucher and Wallet Server (VWS) nodes.

The actual amount of data resulting in an "unacceptable" amount of time to compile an MFile is based on the hardware which the VWS' are running on and business decisions.

The amount of time taken to compile an MFile can be verified in the ccsMFileCompiler log:

ebe_oper@vws01:/IN/service_packages/CCS/tmp$ tail -f ccsMFileCompiler.log
...

Jan 20 06:50:48.798517 ccsMFileCompiler(14122) NOTICE: Informed beServer of MFile change

In this example we can see the MFile took almost 15 hours to compile.

Changes

Large amount of rating information imported into CCS.
