Error description
loop in DSNXOCCX offset1D70 offset1DF8 during bind/prepare of a query with over 32K predicates. The problem can occur in V11 or V12 but depends on what happens to be in storage at the location pointed to by the overflowed variable. Additional Keywords: ZSA2

Problem summary
**************************************************************** * USERS AFFECTED: All Db2 11 and Db2 12 for z/OS users who * * have a query containing over 32K predicates * **************************************************************** * PROBLEM DESCRIPTION: An infinite loop can occur in DSNXOCCX, * * DSNXOGP, or other modules during * * bind/prepare of a query containing * * over 32K predicates * **************************************************************** * RECOMMENDATION: * **************************************************************** An endless loop can occur in DSNXOCCX during bind or prepare of a query containing over 32K predicates. A variable overflowed causing the loop to run endlessly. Depending on the storage that happens to be located where the overflowed variable is pointing, the loop may require bringing down Db2 in order to terminate the thread. This bug can also cause looping in DSNXOGP or other modules. Additional Keywords: LOOP DSNXOCCX INFINITE ENDLESS SQLLOOP LOOP DSNXOGP ZSA2
Problem conclusion
The overflowed variable is updated to allow for over 32K predicates.
