DB2 - Problembeschreibung
| Problem IT05945 | Status: Geschlossen |
LINUX ONLY: DB2GCF MIGHT REPORT INCORRECT STATUS DUE TO ASLR. | |
| Produkt: | |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 | |
| Problembeschreibung: | |
The db2gcf command might report instance state as Operable even
if the instance is up and running.
For example:
$ db2start
SQL1063N DB2START processing was successful.
$ db2gcf -s -p 0
DB2 State
Member 0 : Operable
The db2gcf command should report 'Available' if the instance is
up.
Users can see the db2diag.log entries like as below, it
indicates shmat() subroutine failed due to ASLR (Address space
layout randomization) feature in Linux operating system.
DB2 supports ASLR in V10.1 or later, so db2gcf should handle the
error properly.
