DB2 - Problem description

Problem IT25965 Status: Closed

HADR GRACEFUL TAKEOVER ON PURESCALE COULD TIME OUT WAITING FOR PRIMARY
DATABASE TO PROGRESS DUE TO GLFH LOTCH CONTENTION.

product:
DB2 FOR LUW / DB2FORLUW / A50 - DB2
Problem description:
Sometimes a pd dump function would need to acquire glfh lock to
check if the database has been poisoned.

However, this action could be blocked as another member could be
holding the glfh lock, preventing the dump function to do a
simple check.

The stack should show something like this:

#4  0x00007ffff026a0e6 in sqlpUpgradeLock(sqeBsuEdu*,
SQLP_LOCK_INFO*) () from
/home/db2inst1/sqllib/lib64/libdb2e.so.1

#5  0x00007ffff025ce0c in sqlpValLotch::getSDComplex(unsigned
long, unsigned long, int const*, char const*, unsigned long) ()
from /home/db2inst1/sqllib/lib64/libdb2e.so.1

#6  0x00007ffff035bbf2 in sqlrr_dump_ffdc(sqlrr_cb*, int, int)
() from /home/db2inst1/sqllib/lib64/libdb2e.so.1

#7  0x00007ffff09e60fc in sqlzeDumpFFDC () from
/home/db2inst1/sqllib/lib64/libdb2e.so.1
