Example: How log block identifiers are generated

The following is an example of how log block identifiers are generated:
  • The log block identifier generated for the first log block is one.
  • The first log block is one hundred bytes. The length of the control information system logger adds to a log block for this log stream is 25 bytes: this information was found using the IXGQUERY service.
  • The block identifier for the second log block is generated by adding the first log block identifier to the length of the first log block and the length of the control information: 1+100+25 or 126.
  • The 2ND log block is 50 bytes in length, and system logger again added 25 bytes of control information. The block identifier for the third block is 50+25+126 or 201.
