RECON record types

The records in the RECON data set store information about logging activity and events that can affect the recovery of the database.

Content description of the keys in RECON records

To view the layout of the entire RECON record, see the following table. Consider these points as you examine the records:

  • The RECON key size is 32 bytes.
  • The last three bytes of the key contain either of the following values:
    • Reserved, and contain zeros.
    • First byte=0 and the last 2 bytes=key segment number.
  • Time stamps have the following characteristics:
    • Time stamps are 12 bytes.
    • The symbolic UTC format is:

      YYYYDDDFHHMMSSTHMIJUAQQS

      An example of the UTC format is: 2004006F211432800000032D

    • DSPTIMES (DFSTIMES) contains time stamp structure information.

The following table shows the RECON record types.
