DSNTIPH: System resource data set names panel

The entries on the DSNTIPH panel specify the names of bootstrap data sets, active logs, and archive logs. These entries also specify the number of copies (1 for single logging or 2 for dual logging) for the active and archive logs.

Start of changeFields 1, 2, 4, 5, 7, and 8 on the DSNTIPH panel contain the prefix that was entered in the BSDS AND ACTIVE LOG ICF CATALOG ALIAS field on installation panel DSNTIPA4. If you scroll back to panel DSNTIPA4 and change the BSDS AND ACTIVE LOG ICF CATALOG ALIAS value, the values for fields 1, 2, 4, 5, 7, and 8 on DSNTIPH change. When you scroll from panel DSNTIPA4 to panel DSNTIPH, check these values and enter them again if necessary. In MIGRATE or UPDATE modes, the BSDS AND ACTIVE LOG ICF CATALOG ALIAS value cannot be changed, so the fields on DSNTIPH are not affected.End of change

Dual logging improves reliability of recovering and, for active log reads, eases device contention.

Recommendation: Specify dual logging for both active and archive logs. If you specify dual logging, and an error occurs during offload to the archive logs, Db2 restarts the archive process using the second copy of the active log.
