File Name
| Library
| Description
|
---|---|---|
CCT
| datalib
| Contains information about capture registrations. This file is used by the PowerExchange Listener and PowerExchange Condense. The PowerExchange Listener job opens the file in read/write mode, whereas PowerExchange Condense only reads the file.
|
CDCT
| datalib
| Contains information about the condense files for extraction processing. PowerExchange Condense opens the file in read/write mode to update CDCT information. After a warm start, PowerExchange Condense synchronizes the CDCT file with the current checkpoint file. The PowerExchange Listener job reads the CDCT information on behalf of data extraction processes to find the condense files to process.
|
CDEP
| datalib
| Contains information about each extraction process that has run to provide an audit trail. The PowerExchange Listener uses this file to provide output to extraction processes and input to application groups in PowerExchange Navigator.
|
CFG
| datalib
| Contains the DBMOVER member with the PowerExchange configuration statements. Some of these statements are applicable to PowerExchange Condense.
|
CFGCOND
| condlib
| Contains the CAPTPARM member with the PowerExchange Condense parameters.
|
CHKPTV nn
| condlib
| CHKPTV nn checkpoint files are dynamically created and deleted by PowerExchange Condense based on parameters in the CAPTPARM member. The primary purpose of the checkpoint files is to provide the restart and sequence tokens, which indicate the log position from which to resume reading uncommitted UOWs and the the position at which to release data records that have not yet been processed. The secondary purpose of the checkpoint files is to reconstruct the CDCT file if you need to resume processing from an older point in time.
Informatica recommends the use of nine checkpoint files so that you are likely to have enough checkpoint files from which to reconstruct the CDCT file.
|
DTLMSG
| dtllib
| Contains prototype strings for PowerExchange messages.
|
Full condense file
| condlib
| A condense file that is produced at
condlib /FULL* if you select Full condense processing.
|
LICENSE
| dtllib
| Contains the PowerExchange license key for PowerExchange and the PowerExchange options that you purchase.
|
LOG
| datalib
| Contains the PowerExchange message log member, DTLLOG, that includes messages about PowerExchange Condense and PowerExchange Listener processing when alternate logging is
not enabled.
Because PowerExchange writes a lot of information to this file, you should perform routine maintenance on it to ensure that it does not become too large. Informatica recommends that you use the CLRPFM command to clear the file.
If you enable alternate logging by specifying the TRACING statement in the DBMOVER member, PowerExchange creates message members in the file named JOB job_number in the
datalib library. The member names have the prefix that is specified in the TRACING statement.
|
Partial condense file
| condlib
| A condense file that is produced at
condlib /PARTIAL after each file switch if you select Part condense processing.
