LOGGING_OPTIONS Parameters

In the LOGGING_OPTIONS substatement of the DEFINE statement, you can set logging parameters for the PowerExchange Logger.

Syntax:

LOGGING_OPTIONS
  [LOG_INBUFF=number,]
  [LOG_OUTBUFF=number,]
  [ACTIVE_LOG_MODE=mode,]
  [ARCHIVE_LOG_MODE=mode,]
  [ERDS_LOG_MODE=mode]

Parameters:

The following table describes the LOGGING_OPTIONS parameters:

Parameter	Description	Valid Values
LOG_INBUFF	Defines the number of 4-KB buffers used for reading the active and archive logs.	1 through 60 (decimal). Default is 28.
LOG_OUTBUFF	Specifies the size, in 4-KB buffers, of the output buffer that the PowerExchange Logger uses for writing the active and archive log data sets.	1 through 50 (decimal).
ACTIVE_LOG_MODE	Specifies whether the PowerExchange Logger writes to one or two active log data sets at a time.	SINGLE . The PowerExchange Logger uses one active log at a time. DUAL . The PowerExchange Logger writes to a primary log and a secondary backup log simultaneously. Default is DUAL. Informatica strongly recommends that you use dual logging.
ARCHIVE_LOG_MODE	Specifies whether the PowerExchange Logger writes to one or two archive log data sets at a time. The PowerExchange Logger generates archive logs when the active log is off-loaded.	SINGLE . The PowerExchange Logger writes to one archive log at a time. DUAL . The PowerExchange Logger writes to a primary log and a secondary backup log simultaneously. Default is DUAL. Informatica strongly recommends that you use dual logging.
ERDS_LOG_MODE	Specifies whether the PowerExchange Logger writes to one or two PowerExchange restart data sets (ERDS) at a time.	SINGLE . The PowerExchange Logger uses one restart data set at a time. DUAL . The PowerExchange Logger writes to a primary restart data set and a secondary backup restart data set simultaneously. Default is DUAL. Informatica strongly recommends that you use dual logging.

Usage Notes:

You must specify at least one parameter in the statement.

If you specify multiple parameters, use a comma (,) as a separator character. The last parameter must not end in a comma.
