Problem accessing WLSE's GUI after upgrading to 2.7.1

Question

Hi,
I tried to upgrade from 2.5 to 2.7 and then to 2.7.1, and I can't connect to WLSE anymore with web browser.
In fact, when i'm going to : http://wlse_ip_address:1741, i have the page where i can enter my login/password (which work with telnet as well as console connection) and then there's a loading page which never stops.
So then I tried to install 2.7 from the recovery CD... But same problem again.
Do you have any idea ?
Thanks for your help
PS : I already checked the possible solutions from "faq".

Answer 1

I found this command last day with a search on the cisco web site on "snmphandler" and i think this can be very helpfull. I will try it this morning with my customer:
reset device-snmp
Resets the WLSE's community strings to the default.
Caution This command is intended as a last resort; use it only if you cannot restart the WLSE in any other way. You will lose the community strings and must re-enter them as described below under Usage Guidelines.
Syntax Description
reset [ device-snmp | help ]
Usage Guidelines
This command is intended for restarting the WLSE if the tomcat process fails and the cause for the failure was corruption of the SNMP community string file. In that case, the Web interface will not be available, but the CLI will be available. The procedure follows.
Step 1 Log in to the CLI as admin <http://www.cisco.com/en/US/partner/products/sw/cscowork/ps3915/products_user_guide_chapter09186a008052db78.html> or as another user who has the System Administrator role.
Step 2 Run the service status command to check the status of the tomcat process. If the status is "Failed to run", proceed to the next step.
Step 3 Run the show tomcatlog command. It should contain these error messages about the SNMP community file:
MESSAGE: SnmpLibHandler: About to initialize SNMP Errors found while
parsing community strings.
FATAL ERROR: SnmpLibHandler: unable to read SNMP communities file:
/var/adm/CSCOets/config/cwsi/anisnmp.conf
Step 4 Run the reset device-snmp command.
? The file is reset and previously defined communties are lost.
? The community strings are reset to *.*.*.*:public::10:1:::public.
? The old SNMP community file is placed in the WLSE's log area. To view the file, select Admin > Appliance > Status > View Log File. Select the anisnmp.conf.log file.
Step 5 Log into the Web interface as admin <http://www.cisco.com/en/US/partner/products/sw/cscowork/ps3915/products_user_guide_chapter09186a008052db78.html> or as another user who has the System Administrator role.
Step 6 Select Devices > Discover > Device Credentials > SNMP Communities and re-enter your community strings.
