BACKUP MAY HANG DUE TO DB2VEND NOT BEING INITIALIZED |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
A backup process may hang under Solaris operating system because
one of the child db2vend process may be waiting to acquire an
AIO lock. This will only affect the backup processing. You can
identify this issue if the backup seems not to respond and by
running "db2ptree". The db2ptree will show some db2vend
processes started and others being db2sysc at the same tree
level
