Changes


A configuration backup created in an OS release prior to OS8.7 is restored on a system running OS 8.7.x


 


Cause


OS 8.7 introduced the "CLI idle timeout" parameter under configuration preferences.


When a configuration backup from an a prior OS is restored this expected parameter is missing.


 


Solution


 Please open a service request for Oracle Global Support to address this issue.




This process will allow the user to login to the Appliance BUI after restoring a pre-OS8.7 configuration backup.


 


1. Drop to the appliance shell and 'cd' to the users subdirectory of stash.


ZFSSA:> confirm shell
...
ZFSSA# cd /var/ak/stash/com/sun/ak/xmlrpc/user/


 


2. Find the stash object for the user 'root'.


ZFSSA# for i in *;do if aknv $i/obj|grep -q "logname = root";then echo $i/obj;fi;done
bd1c7e89-5b83-4e01-9dae-fa6fded03cbe/obj


 


3. Create a backup of the current 'root' user object.


ZFSSA# cp bd1c7e89-5b83-4e01-9dae-fa6fded03cbe/obj /var/ak/dropbox/stash.root_user.orig.obj


 


4. Create an XML version of the binary stash object:


ZFSSA# aknv -x bd1c7e89-5b83-4e01-9dae-fa6fded03cbe/obj > /tmp/stash.root_user.orig.xml


 


5. Confirm the required parameter is missing.


ZFSSA# grep idle_timeout /tmp/stash.root_user.orig.xml
ZFSSA#


 


6. Add the required entry to a new copy of the XML file.


ZFSSA# perl -slpe 'print $s if $. == $n' -- -n='grep -n session_timeout /tmp/stash.root_user.orig.xml | cut -d: -f1' -s=" <nvpair name='cli_idle_timeout'><int32 value='-1'/></nvpair>" /tmp/stash.root_user.orig.xml > /tmp/stash.root_user.new.xml


 


7. Confirm the new line.


ZFSSA# diff /tmp/stash.root_user.orig.xml /tmp/stash.root_user.new.xml
24a25
> <nvpair name='cli_idle_timeout'><int32 value='-1'/></nvpair>


 


8. Disable AKD.


ZFSSA# svcadm disable -st akd


 


9. Convert the edited object to stash's binary format to replace the object identified in step 2.


ZFSSA# aknv -S /tmp/stash.root_user.new.xml > bd1c7e89-5b83-4e01-9dae-fa6fded03cbe/obj


 


10. Verify the entry in the binary file.


ZFSSA# aknv bd1c7e89-5b83-4e01-9dae-fa6fded03cbe/obj | grep idle_timeout
cli_idle_timeout = -1


 


11. Restart akd and test the BUI login.


ZFSSA# svcadm enable akd
ZFSSA# pgrep akd | wc -l
3
ZFSSA# pgrep akd | wc -l
2
ZFSSA# exit


 


The above procedure works for other local users configured in AKD.


The default cli_idle_timeout value is '-1', which is 'infinite'
