1 - Purpose of Document

This document presents the design of the file processor framework. This framework can be used to load and export any type of ASCII-based file. The design has been based on loading and exporting of CDR (Call Detail Records) ASCII files. As such must references have been made to CDR files. However, the same concept has been used for loading/exporting other non-CDR ASCII based files

2 - Design Overview

A CDR File is a file containing CALL DETAIL RECORDS in a pre-defined format and order. This document aims at modelling a CDR File in a generic way. This could also be extended to any normal ASCII-based file. As such this document could also be used to model any ASCII-based file.

2.1 Design

A CDR file is made up of one or more logical CDR Records separated by a pre-defined separator (delimiter). The default separator is the systems line separator which in most cases is a carriage return line feed.

A CDR file has three types of records.

  1. Header Record
  2. Body Record
  3. Trailer Record.

A CDR record is made up of one or more CDR fields, separated by a pre-defined separator.
A CDR record may be identified by one or more CDR_RECORD_IDENTIFIERs. The default record (NO CDR_RECORD_IDENTIFIER) is a detail record.
A CDR Field contains values in a pre-defined format, which will henceforth be referred to as a CDRFieldFormatDef (CDR_FIELD_FORMAT_DEF).

BILLING_SOURCE_CLASS

Class used to model the table defined in the column 'BILLING_SOURCE_TABLE_NAME'

FILE_NAME_SUFFIX

Suffix (extension) to be added to the export filename

FILE_NAME_GENERATOR_METHOD

Method on the BILLING_SOURCE_CLASS

...

used

...

to generate a filename during export. This method must take the ID of the record in the 'BILLING_SOURCE_TABLE_NAME'

...

table, and the CDR_FILE_DEF ID as parameters. For example for exporting a CDR file, the ID will be the ID of the appropriate SP_FILE_HEADER record linked to the rated BILLING_RECORDs (BILLING_RECORD.SP_FILE_ID = SP_FILE_HEADER.ID) being exported.

PRE_PROCESSOR_METHOD

Method in the BILLING_SOURCE_CLASS called before processing a file. The method must take CdrFileDef object as parameter. Could be used to validate if a file has already been loaded or to delete all records in a table before loading.

POST_PROCESSOR_METHOD

Method in the BILLING_SOURCE_CLASS called after processing a file. The method must take CdrFileDef object as parameter. Could be used for validating contents of the detail against information on the trailer.

RECORD_FOR_HEADER

Possible values are Y and N. This column is solely taken into an account, if the PERSIST column has the value Y. In case the first line in the loaded file must be stored in the BATCH_FILE_LINE table, the RECORD_FOR_HEADER column must be set to Y.

STATUS_COLUMN_NAME

String value. Defines the column name for status of billing source table. If left empty a default name of STATUS is used.

NUMBER_OF_RECS_COLUMN_NAME

String with default value 'NUMBER_OF_RECS'. Defines the column name, where the number of the content lines in a loaded file must be stored.

DATE_LOADED_COLUMN_NAME

String with default value 'DATE_LOADED'. Defines the column name, where the time of the loading must be stored. The column is mandatory in the billing source table.

SAVE_RECORD_ORDER

Char with possible values 'Y'/'N' and default value 'N'. Defines whether line number of a loaded record must be stored in the db.

RECORD_ORDER_COLUMN_NAME

String with default value 'LINE_IN_FILE'. Defines the column name, where the line number of the loaded record must be stored.

STATUS_VALUE

String with default value '0'. Defines the status of the loaded file.

COMMENT_COLUMN_NAME

Defines the column name in the billing source table (defined in the column billing_source_table_name), where error messages are posted, if a file generation fails. Not mandatory in the billing source table. If left out, error messages are simply not posted in the billing source table.

PRE_PROCESSOR_HOOKPOINT_KEY

Sets the Hookpoint key to be called in the pre-process. Is invoked with the prefix FILE_PROCESSOR_.

POST_PROCESSOR_HOOKPOINT_KEY

Sets the Hookpoint key to be called in the post-process. Is invoked with the prefix FILE_PROCESSOR_.

FILE_NAME_COLUMN_NAME

The value of FILE_NAME_COLUMN should be the name of the column from the Source table where the generated filename will be saved to. If CDR_FILE_DEF.FILE_NAME_COLUMN_NAMEis empty, the FILENAME column of Source table will be used to save the filename.

If a flat file, an XML file and a JSON file should be generated on the same source record: Then define 3 different CDR_FILE_DEF entries, each with proper column name set in the FILE_NAME_COLUMN_NAME. For example:

  • First CDR_FILE_DEF entry for flat file generation: CDR_FILE_DEF.FILE_NAME_COLUMN_NAMEis empty. So the generated flat file name will be saved to FILENAME column of Source table
  • Second CDR_FILE_DEF entry for XML file generation: CDR_FILE_DEF.FILE_NAME_COLUMN_NAME= XML_FILE_NAME. So the generated XML file name will be saved to XML_FILE_NAME column of Source table
  • Third CDR_FILE_DEF entry for JSON file generation: CDR_FILE_DEF.FILE_NAME_COLUMN_NAME= JSON_FILE_NAME. So the generated JSON file name will be saved to JSON_FILE_NAME column of Source table

3.1.2 CDR Record Definition (CDR_RECORD_DEF)

is

set,

...

then

...

the

...

record

...

will

...

be

...

identified

...

using

...

a

...

CDR_RECORD_IDENTIFIER.

...

Possible

...

values

...

are

...

'ALL'

...

or

...

'AT_LEAST_ONE'

...

.

...

These

...

are

...

explained

...

in

...

subsection 3.1.3

...

.

PERSIST

Determines if a record should be persisted. Sometimes, one may not need to persist a CDR_RECORD (as in the case where the record is a header of column name). Default value is 'Y' (meaning persist data) otherwise it is 'N' (meaning do not persist data).

RECORD_CLASS

The fully qualified class name of that models the table defined by the RECORD_TABLE_NAME

SOURCE_TABLE_KEY

This columns holds the column name in RECORD_TABLE_NAME table that points to the SOURCE TABLE. This is used by CDR_RECORD_DEFs.
For file generator:
For CDR_RECORD_DEF entries having CODE = 'DETAIL': If this field is empty, the value 'SP_FILE_ID'

...

is

...

used.

...


For

...

CDR_RECORD_DEF

...

entries

...

having

...

CODE

...

=

...

'HEADER'

...

or

...

'TRAILER':

...

 If this

...

field

...

is

...

empty,

...

the

...

value

...

'ID'

...

is

...

used.

...

This

...

is

...

usually

...

the

...

case

...

when

...

the

...

HEADER

...

table

...

is

...

also

...

the

...

source

...

table.

...

So

...

if

...

the

...

file

...

should

...

contain HEADER, TRAILER and DETAIL records and the data model in the DB contains an extra table for holding the SOURCE info, then all three CDR_RECORD_DEF entries (For HEADER, TRAILER and DETAIL) must contain appropriate value in SOURCE_TABLE_KEY. 
For file loader:
This is used only by CDR_RECORD_DEFs with CODE = 'DETAIL'. If this field is empty, the value 'BILLING_SOURCE_ID' is used.
For example if the 'BILLING_SOURCE_TABLE_NAME' - of the appropriate CDR_FILE_DEF record - is IBASIS_MONTH and the detail record table name (RECORD_TABLE_NAME) is IBASIS_RECORD where IBASIS_RECORD.IBASIS_MONTH_ID = IBASIS_MONTH.ID, then the SOURCE_TABLE_KEY will have a value of ‘IBASIS_MONTH_ID’.

STATUS_COLUMN_NAME

String value. Name of the column where the record status must be stored.

STATUS_VALUE

Value to be set in status column defined in STATUS_COLUMN_NAME.

HOOKPOINT_KEY

If this is set, it will save this value into RECORD_TABLE_NAME.HOOKPOINT_KEY, not a mandatory value.

SEQUENCE

SEQUENCE column is used to define multiple record definitions for same record type (i.e. for example multiple record definitions for HEADER record for same File Definition) and define the sequence in which they can appear in the exported file. For example, if an exported file should contain 3 lines in the header and each of these lines has a difference structure, then it is possible to define 3 HEADER record definition entries with SEQUENCE 1, 2 and 3 based on the required order of these lines in the file. Then the file processor with get all the header definitions and handles one by one in the defined sequence, writing the lines matching that record definition only. 

Important Note: If only one record definition entry is needed for a record type, then the SEQUENCE Column of that record definition entry must be left empty.

3.1.3 CDR Record Identifier (CDR_RECORD_IDENTIFIER)

A CdrRecordIdentifier consists of:

  • a CDR_RECORD_DEF_ID (CDR Record DEF)
  • a field position (CDR_FIELD_POSITION),

...

  • and

...

  • a

...

  • default

...

  • value

...

  • (DEFAULT_FIELD_VALUE).

...

A

...

Cdr

...

Record

...

Definition

...

can

...

have

...

zero

...

or

...

more

...

CDR_RECORD_IDENTIFIERs.

...

The

...

CDR

...

Record

...

Identifier

...

is

...

used

...

for

...

identifying

...

a

...

CDR

...

RECORD.

...

For

...

example,

...

a

...

Header

...

Cdr

...

Record

...

might

...

be

...

identified

...

by

...

its

...

first

...

field

...

being

...

‘HD’.

...

In

...

this

...

example,

...

a

...

header

...

CDR_RECORD_DEF

...

will

...

have

...

an

...

entry

...

in

...

the

...

CDR_RECORD_

...

IDENTIFIER table

...

with

...

CDR_FIELD_POSITION

...

equalling 1

...

and

...

the default

...

field

...

value equalling ‘HD’. In this situation, the RECORD_IDENTIFIER_TYPE

...

attribute

...

in

...

the

...

CDR_RECORD_DEF

...

table

...

will

...

be

...

‘ALL’.
In another example,

...

a

...

CDR

...

detail

...

record

...

might

...

be

...

identified

...

by

...

at

...

least

...

one

...

of

...

the

...

following

...

values;

...

‘20’,’21’,’22’, in its first field. In this scenario the CDR_RECORD_DEF

...

for

...

the

...

detail

...

record

...

will

...

have

...

three

...

entries

...

in

...

the

...

CDR_RECORD_IDENTIFIER

...

table

...

each

...

with

...

a field

...

position

...

equal

...

to

...

1

...

and

...

default

...

field

...

value

...

‘20’,’21’,’22’, respectively.

...

Used

only

...

for

generating export files. The BRAND_ID must equal the BRAND_ID on the BILLING_SOURCE_TABLE_NAME of the CDR_DEF_ID record defined by the ID of CDR_FILE_DEF processed by this CDR_FILE_PROCESSOR record. For example, for export of CDR files using the SP_FILE_HEADER as source table, the only records in the SP_FILE_HEADER table whose BRAND_ID is the same as the BRAND_ID for this record will be processed by this record.

3.1.11 Invoking Hookpoint in the Pre or Post Process

It is possible to invoke a hookpoint in both the pre process and post process of file processing. This functionality is activated by adding the Hookpoint Key to either the PRE_PROCESSOR_HOOKPOINT_KEY or POST_PROCESSOR_HOOKPOINT_KEY column of the CDR_FILE_DEF. If the PRE_PROCESSOR_HOOKPOINT_KEY value is not emty the hookpoint key with the prefix "FILE_PROCESSOR_" with the brand of the CDR_FILE_PROCESSOR is attempted invoked during the specific process. The particular CdrFile object by the FileProcessor is inserted into context under the key "CDR_FILE".

3.2 Generating (Export) Files

In order to generate CDR files for export, in addition to the tables defined in 3.1 above, the following table must also be defined.

Unlike for loading where the header/trailer information of a CDR File is stored in a BILLING SOURCE table, the header/trailer information used for generating an export file is stored in an SP_FILE_HEADER table and the BILLING RECORD table must have a column named SP_FILE_ID, that points to the SP_FILE_HEADER record that will be used to generate the export file. An SP_FILE_HEADER table must have at least the following columns ID, FILENAME, BRAND_ID, STATUS and FILE_CREATED_DATE. These columns are inherently used within the model.

Sometimes, when generating a file for export, some information needed for export (usually in the header and/or trailer records) is not yet present. This information could be generated by a pre-defined stored procedure that will be called before any file is generated for export. If such a pre-defined stored procedure is needed, then it must accept one the SP_FILE_HEADER_ID as parameter since all processing must depended on the SP_FILE to be generated. The column PRE_EXPOR_PROCEDURE on the CDR_FILE_DEF table holds the value of the pre-defined stored procedure. If such a procedure exists, it will be called before the export file is generated.

To generate any other file, the header and trailer records should be stored in the BILLING_SOURCE_TABLE_NAME table defined in the CDR_FILE_DEF while the detail record definition (CDR_RECORD_DEF) pointing to this CDR_FILE_DEF should have a SOURCE_TABLE_KEY appropriate defined as described in section  3.1.2 CDR Record Definition (CDR_RECORD_DEF) and the BILLING_SOURCE_TABLE_NAME table must have a column following columns ID, FILENAME, BRAND_ID, STATUS and FILE_CREATED_DATE. All other processing is the same as described above.

It should be noted that only records in the BILLING_SOURCE_TABLE_NAME table that have status = 1 (ready for export) will be pickec up by the CDR_PROCESSING_ENGINE (CODE = 'GENERATOR')

3.3 Setup Of File Loader and Generator Engines

The CdrFileProcessing engine handles loading files and generating files for export. The CdrFileProcessignEngine takes at most three parameters.

  • Parameter 1 is the engine name (“CDR_FILE_LOADER_ENGINE” (for CdrFileLoaderEngine) or “CDR_EXPOR_FILE_GENERATOR_ENGINE” (for CdrExportFileGeneratoeEngine)), or “CDR_FILE_PROCESSING_ENGINE” (for both loading and file generation)).
  • Parameter 2 is the Engine Instance Number
  • Parameter 3 is the type of processing (“LOADER” (for CdrFileLoaderEngine) or “GENERATOR” (for CdrExportFileGeneratoeEngine)).
    If parameter 3 is not set, then the engine will perform both loading and export file generation.

4 Parameter Setup

The following table shows the parameter setup that can be used by CdrFileprocessorEngine. The parameters are under the node "FILE_PROCESSING".

NAME

VALUE

String

Yes

Defines whether the engine should move files if they do not meet the pattern name criteria

MAX_FILES_TO_LOAD

integer bigger than 0

Integer

Yes

Defines the number of files that are processed in a single engine iteration. If not present, the default value is 50

BATCH_SIZE

integer bigger than 0

Integer

Yes

Number of SQL statements size used to load in batch. If not present, the default value is 100

DB_SYS_PACKAGE_NAME

SYS/CORE_SYS

String

Yes

(Mandatory if CORE_SYS package is used)

Defines the name of the sys package to be used in SQL-statements

Default SYS (if this parameter is not defined)

CHARACTER_ENCODING<Valid character encoding>StringYesDefines the character encoding to be used while importing the files. If this parameter exists, the encoding specified in this parameter will be used to read the file. Otherwise the default encoding will be used.

5  MONITORING

5.1 File Generator

If the File Processor engine cannot generate the file due to an exception, it will insert an entry into EXCEPTION_LOG table. The ID from EXCEPTION_LOG.EXCEPTION_STACK_TRACE_ID can be used to find the corresponding entry from EXCEPTION_STACK_TRACE, which contains the stack trace of the exception. 

Code Block
languagesql
select * from EXCEPTION_LOG where TABLE_NAME = 'CDR_FILE_PROCESSOR' and SOURCE_KEY = '<CDR_FILE_PROCESSOR.NAME for corresponding CDR_FILE_PROCESSOR entry>' order by id desc; 

5.1 File Loader

If the File Processor engine cannot load  the file due to an exception or due to errors while parsing the file, it will insert an entry into LOAD_ERRORS table. 

File Processor engine inserts an entry into CDR_FILE_PROCESSOR_LOG table upon successful loading of the file.
