Status: Geschlossen |
DB2 INSTANCE ON SOLARIS CAN BECOME INACCESSIBLE AND ENTER A HUNG STATE. |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
DB2 instance on solaris can become inaccessible and
enter a hung state.
After a period of activity a DB2 instance became inaccessible
and entrered a hung state.
Looking at the DB2 threads they can been seen to be on async I/O
requests. However the Solaris async I/O worker threads all
appear to be idle and waiting on requests.
This can be due to a solaris defect 6972029 close(-1) cancels
all aio for all open file descriptors. |
