How to reset OVM Manager admin password

I recently had to recover the admin password for OVM Manager.

The email address was not set up correctly so I couldn’t use the standard way to do that.

A quick search in Google and I got a link on Oracle Documentation. Unfortunately you can only change the password and not reset it.

Next link to a post using a script provided by Oracle. I didn’t use it as it is only for OVM 2.2 and I have version 3.3.

I succeeded by using this blog post and changing the password directly in Oracle database.

Of course you need the database OVS or SYS password.

--Login to database as SYS user or OVS user
-bash-3.2$ . oraenv
ORACLE_SID = [XE] ? XE

-bash-3.2$ ./sqlplus ovs/ovs@XE

-- Take a backup from OVS_USER table
 SQL> create table OVS_USER_BKP as select * from OVS_USER;

-- Update the password 
 SQL> UPDATE OVS_USER set password=create_encrypt_passwd('admin') where account_name='admin';
 1 row updated.

SQL> commit;
 Commit complete.

PS : once this issue solved a new one raised : ERR_SSL_VERSION_OR_CIPHER_MISMATCH.

The solution is in the Oracle document in Oracle support : “Oracle VM Manager 3.3: getting error ERR_SSL_VERSION_OR_CIPHER_MISMATCH in Chrome (Doc ID 2099148.1)”

How to unbrick LG GPad 8.3?

Since 3 days ago my LG GPad is stuck at the logo when booting. It stays at the LG Logo screen and restart again after few seconds.

I don’t know where it comes from as I didn’t change the firmware and I don’t remember installing any app just before that.

Here are the steps to follow. Be aware, this is a full reset, you will need to do a full reinstallation of all your apps.

  1. Make sure your device is fully charged and turned off.
  2. Simultaneously press and hold the power and volume down buttons.
  3. When the LG logo shows up, release the power button only.
  4. Now press and hold the power and volume up button while keeping your hold on the volume down button.
  5. When the factory reset screen appears, release your hold on all buttons.
  6. Press the power button to continue.
  7. Press the power button again to confirm if you’re sure you wish to continue with the reset.

I am giving the steps here as I struggled to get the right steps. I usually found the steps without the up button.

Why hosted on Linux on Power ?

UPDATE : I started hosting this blog on a Linux on Power server in OVH. OVH stopped the beta test and is now in process of hosting only bare-metal servers.

Since Linux on Power is available, I wanted to be able to host my blog on this platform. Why ? I wanted to show that Linux on Power is a Linux as any other one and as easy to manage.

OVH has its own offering on the subject and I have the luck to get some coupons.

The whole Linux installation process is easy through the website. I used Ubuntu 14.04 as I  know pretty well Ubuntu and it was the first version available in Little Endian.

Installing a LAMP server is also as easy as on Linux on Intel. I used the same documentation than on my Linux on Intel servers. The behavior is exactly the same.

I installed WordPress 4.1 myself, following once again the standard documentations.

PS : I still have some coupons if you want to try Linux on Power too.
