Cause
Solution
Applies to:
Oracle Applications Manager - Version: 11.5.9 to 11.5.10
This problem can occur on any platform.
Symptoms
On entering Oracle Applications Manager (OAM) to check on the status of workflow components (Workflow Manager, "Go" button), under Workflow Metrics, both Work Items and Agent Activity displayed the message
"BIB-7000 Cannot access X Server"
Navigating to OAM to view Activity Monitors or other Graphics also reflect the same error.
Also, Configuring the Java Mailer in OAM - the page hangs and then displays Page Cannot be Displayed
Changes
OAM requires the jserv.properties "wrapper.env=DISPLAY" setting to be consistent throughout the application environment and also it needs to correspond to the correct server where xhost is enabled.
Cause
The DISPLAY setting is not consistent throughout the environment or xhost has not been enabled on the server where the DISPLAY setting is directed to.
If DISPLAY is set and xhost was enabled, another cause is, that the xhost session was not left running on the Xserver machine.
Solution
As ROOT on the Console machine with the Graphics Display
1) $ uname -n
> record the exact value returned
2) - For LINUX:
$ cd /usr/X11/bin
or
$ cd /usr/X11R6/bin
- For SOLARIS:
$ cd /usr/openwin/bin
- For AIX & HP-UX see Note: 361535.1 to setup 'Headless' support for xServers
3) $ xhost +
> LEAVE THIS SESSION OPEN ON CONSOLE -- DO NOT "SU APPLMGR"
4) Open a New Session and signon as APPLMGR
$ adstpall.sh apps/apps
> Stop all the services on all nodes in the environment
5) Open a New Session and signon as APPLMGR or clear the env of the previous APPLMGR session
$ DISPLAY=<same value as #1>:0.0; export DISPLAY
> See the ":0.0" , make sure that is specified
6) $ echo $DISPLAY
> ex:
$ <hostname from #1>:0.0
7) On all the Nodes in this environment -- if this is a multiple node, then repeat on cp, forms/web & admin nodes
$ cd $IAS_ORACLE_HOME/Apache/Jserv/etc
$ cp jserv.properties jserv.properties.bak
$ vi jserv.properties> Search down for "wrapper.env=DISPLAY"
9) Reassure or change the setting to match the following syntax ( repeat on cp, forms/web & admin nodes)
wrapper.env=DISPLAY=<hostname from #1>:0.0
> The hostname value in the DISPLAY must be the same in all nodes, it must be set to the value of "uname -n"
from step #1
> Setting this in OAM > AutoConfig > Edit Parameters and then running AutoConfig on all nodes
with accomplish the same thing
10) Restart all the services in the same APPLMGR sessions
