Check update
Check Update (CU) is a periodic call to
BlackBerry AtHoc
to get a list of sections and dynamic update (DUA) version. The CU query string has the following format:http[s]://<server_path>/csi/session/action.asp?99=CU&00=<UserId>&01= <SessionId>&02=<obsolete>&03=<AppVersion>&04=2&05=0&...
When CU determines that an update is pending, it initiates a Get Update (GU). That results in the client writing a list of section versions to the log.
The following is a sample from a log:
CU-|ENGINE,0|SKIN,1|TREE,1|CLIENT,5.6.4.0|STYLESHEET,1|ACTIONS,1| 209999990,0,|SYSTEM,551307491|PROVIDER,551307491|SYSTRAY-MENU,549731261|
In the above sample, the format is “|SECTION-NAME,version|”, showing the names and versions of sections that correspond to the registry keys under the desktop app’s user key. For example, the version for PROVIDER is 551307491, which you can see in the user’s registry:
HKCU\Software\
.AtHoc
Corp\PROVIDER\VersionIf the CU is successful, the client shows
in the system tray. If the CU is not successful the client shows
in the system tray.
