D.4.4.1 data/errors Subdirectory

The errors subdirectory within the data subdirectory stores error files that Data Management subsystem components create or move upon detection of errors during file processing.

The system places error files in subdirectories within the errors subdirectory. These error file subdirectories are name-based on the processing date for the files that they contain. The date has the format YYYYMMDD, where YYYY is the four-digit year, MM is the two-digit month, and DD is the two-digit day. The files in the errors subdirectory have the same name as the file in which the error was detected. However, the component that identified the errors appends its extension to the end of the file.

The following table identifies the error file signatures that each component can output to the errors subdirectory.

Table D-15 Error File Signatures Output by Component

Component	Error File
Pre-processor	<data type>_*.XDP.err
Data Loader	<data type>_*.XDL.err
FDT	Order_*.FDT.err TradeExecution_*.FDT.err
MDS	InsideQuote_*.MDS.err MarketCenterQuote_*.MDS.err ReportedMarketSale_*.MDS.err

The IMC utility, runIMC.sh, cleans up the errors subdirectory. The IMC’s configuration file defines the number of days that error files age before their removal.
