Problem description: | |
If a page header is corrupted, db2dart may create a hex dump of the page that is larger than the page. This will occur when the value in begoff is larger than pagesize. For example, consider this page header 000 *A41D 1C91 7B1B 9CD7 5A01 EF73 DBE5 FD52* *........Z..s...R* 010 *A719 B407 3A9B B6FC 9C97 34CD B129 2EE6* *..........4.....* 020 *9FF0 97AB BDFB 0149 E65A C8DA BC0B 226B* *.......I.Z.....k* The hexdump of the page is 0xA41D bytes long, exactly the size of begoff. In this case, the pagesize is 8K, so anything printed after 0x2000 is bogus. When searching for patterns in the hex dump to help the customer identify root cause of the page overwrite, any patterns found after the pagesize will become a 'false positive' and can mislead the investigation | |
