Error description
SQL got abend with DSNKTRAV 2024 because an index manager did not refresh old retraverse stack information set before load replace. SSB_NL_PG and MSAXSPG(2) still had bigger page number than page set boundary (PB0HURP) because the page set shrank by the load replace.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All DB2 for z/OS V10 and V11 index users * * that specify the RELEASE(DEALLOCATE) bind * * option. * **************************************************************** * PROBLEM DESCRIPTION: SQL got an abend with DSNKTRAV:2024 * * after a LOAD REPLACE job reduced the * * size of the index leading to the abend. * **************************************************************** * RECOMMENDATION: * **************************************************************** The module DSNKTRAV abended because previously stored access information was no longer valid due to a LOAD REPLACE that reduced the size of the index. The bind option RELEASE(DEALLOCATE) allows access information to be retained after commit, which in this case kept information that described a larger index than what was left after the LOAD REPLACE completed. The access information listed a page value that was outside the boundary of the index causing the abend. The corresponding V12 APAR is: PI77368
Problem conclusion
Code in module DSNKTRAV has been modified to tolerate accessing an index page that is not within the boundary of the current index.
