Problem IC66050
|
Status: Closed |
THE DB2 LICENSE DAEMON (DB2LICD) MIGHT INHERIT FILE DESCRIPTORS INCLUDES SOCKET FROM APPLICATION PROCESS. |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
The db2 license daemon might be spawned from application when
User Policy is enabled.
Because db2 client code keep track the license with license
daemon in this settings, and might spawn license daemon if it's
not started.
This behavior is expected one, but all the file descriptor
includes sockt will be inherited by db2licd and it might cause
some problems on the application. |

* The license daemonis a long-running process, and so any *
* inheritedfile handles (which include sockets) will be *
* heldopen indefinitely. *
