Lily Wei updated DERBY-4771:
----------------------------
Attachment: derby.log
error-stacktrace.out
Thanks Kristian for the prompt reply and explanation.
Good eyes. I add the "CHECKING" so it is easier for me to see what is going on
for now.
if (tableDescriptor.getTableType() ==
TableDescriptor.BASE_TABLE_TYPE &&
tableDescriptor.getTotalNumberOfIndexes() > 0) {
System.out.println("CHECKING: " +
tableDescriptor.getQualifiedName());
long rows = baseRowCount();
if (statisticsForTable) {
tableDescriptor.markForIndexStatsUpdate(rows);
} else if (rows > 100) {
// Only create statistics if there are "enough" rows.
tableDescriptor.markForIndexStatsUpdate(-1);
}
}
I delete all existing directories before I run the test suites. I run the
testOSReadOnly and it failed as I run it individually. I am attaching the
error-stacktrace.out and derby.log and hope it is helpful to you.
With database status, I mean it allows us to know the state of the database.
i.e. read-only status.
