Default operating parameters for the Capture program

When you create the Capture control tables, default values for the Capture program's operating parameters are saved in the IBMSNAP_CAPPARMS table.

The default values are shown in Table 1 and Table 2.

Table 1. Default settings for Capture operational parameters (Linux, UNIX, Windows, z/OS)
Operational parameter Default value Column name in IBMSNAP_CAPPARMS table

caf n4 not applicable
logread_prefetch Y 3 for partitioned databases; N 4 for nonpartitioned databases not applicable
logreuse n4 LOGREUSE
logstdout n4 LOGSTDOUT
sleep_interval 5 seconds SLEEP
capture_path Directory where Capture was started5 CAPTURE_PATH
startmode warmsi6 STARTMODE
Note:
  1. The Capture control server is the value of the DB2DBDFT environment variable for Windows, Linux, and UNIX, if that variable is specified. There is no default value for z/OS®.
  2. You cannot change the default for the Capture schema. To use another Capture schema, use the capture_schema startup parameter.
  3. Yes
  4. No
  5. If Capture starts as a Windows service, its capture path is \sqllib\bin.
  6. The Capture program warm starts. It switches to cold start only if this is the first time that the program is starting.

Note:
  1. You cannot change the default for the Capture schema. To use another Capture schema, specify the CAPCTLLIB parameter when you start the Capture program. The default values for most other operational parameters are stored in the IBMSNAP_CAPPARMS table.
  2. CLNUPITV has two sub-parameters. By default, the Capture program prunes soon after it starts running and again after every prune interval is reached (which, by default, is every 24 hours).
  3. By default, the Capture program warm starts.
