Ubuntu Hibernate button
Like to use the suspend/Hibernate function of Ubuntu, which saves me time from Bootup.
It find this is in gnome flashback(Metachity) session.only. Would like to try other Gnome new desktop session, but didn't switch to, due to lacking of the hibernate button.
Googled and finally find it is there, just need to press ALT button, and the power off icon becomes PAUSE icon, which means suspend/Hibernate.
Later on, I also find my favorite taskbar / panel by configure it with gnome-tweak-tool

since those files are manually purged and no longer on disk, my workaround for this test database is to temporally clear the archivelog deletion policy.
CONFIGURE ARCHIVELOG DELETION POLICY CLEAR;
Then, re-execute the command again, which went through.

Ubuntu login loop
Upgraded to Ubuntu 15.10 from 15.10, resolved blank screen by playing with gdm/lightdm. Finally lightdm is my choice, which works with the video driver xserver-xorg-video-nouveau.
Then I am facing loop login, read very thoroughly on below two articles.

End up , found the
The hint .xsession_errors saved me, the message is :

Searched the ERRFILE in the file, seems it is not defined.

about RMAN compression
Friday, April 15, 2016
Happened to issue "BACKUP filesperset 2 incremental level 1 DATABASE ;", without knowing that there is no LEVEL 0 backup has been created, for a 11.2.0.3 EE database. As we know , if there is no LEVEL 0 exists, the RMAN will automatically created the very first as LEVEL 0 backup. This is a good feature.
However, based on my below investigation, this feature is not efficient.
While waiting and waiting, which didn't complete within my expect time.
Then I am interested to know what happened, as the time is 5x than what was taken for a fresh LEVEL 0 backup.
Furthermore investigation shows the backupset size is 5.7x times larger than a fresh LEVEL 0 backupset.
This is very surprising. For this case, I learned it is better to have LEVEL 0 pre-created before running LEVEL 1.
Below are technical numbers.

change fast recovery area location, no impact to existing backup
The database RCATT's FRA was set to /rman001/oradata/fast_recovery_area/, now I want to change to another directory, i.e. /dbfra/wiadb01d. Wondering if the recovery catalog still knows it.
The answer is no impact based on my below test.

rman backup set and backup piece concepts
backup piece
The physical file format used to store RMAN backup sets
A backup of one or more datafiles, control files, SPFILEs and archived redo log files. Each backup set consists of one or more binary files called backup pieces. Backup pieces are written in a proprietary format that can only be created or restored by RMAN.

backup set
A backup of one or more datafiles, control files, SPFILEs and archived redo log files. Each backup set consists of one or more binary files called backup pieces. Backup pieces are written in a proprietary format that can only be created or restored by RMAN.
Backup sets are produced by the RMAN BACKUP command. A backup set usually consists of only one backup piece. RMAN divides the contents of a backup set among multiple backup pieces only if you limit the backup piece size using the MAXPIECESIZE option of the ALLOCATE CHANNEL.
Backup Sets and Backup Pieces
RMAN can store backup data in a logical structure called a backup set, which is the smallest unit of an RMAN backup. A backup set contains the data from one or more datafiles, archived redo logs, control files, or server parameter file. Backup sets, which are only created and accessed through RMAN, are the only form in which RMAN can write backups to media managers such as tape drives and tape libraries.
A backup set contains one or more binary files in an RMAN-specific format. Each of these files is known as a backup piece. A backup set can contain multiple datafiles. For example, you can back up 10 datafiles into a single backup set consisting of a single backup piece. In this case, RMAN creates one backup piece as output. The backup set contains only this backup piece.
If you specify the
SECTION SIZE parameter on the BACKUP command, then RMAN produces a multisection backup. This is a backup of a single large file, produced by multiple channels in parallel, each of which produces one backup piece. Each backup piece contains one file section of the file being backed up.
For non-multisection backups, RMAN only records backup sets in the repository that complete successfully. There is no such thing as a partial backup set. This differs from an unsuccessful multisection backup, where it is possible for RMAN metadata to contain a record for a partial backup set. In the latter case, you must use the
DELETE command to delete the partial backup set.

two RMAN tips learned when using disk
1. to delete obsolete command, I have to change the command worked for tape device from
delete noprompt obsolte;
to
delete noprompt obsolte to device type disk;
2. When using FRA, I can't use FORMAT option as discussed here, irregardless I was happy with the conversion for device type tape BACKUP FULL FILESPERSET 1 FORMAT 'DB%I.%d_%N_%U' DATABASE;. Otherwise, the backupset is written to $ORACLE_HOME/dbs instead FRA location.
delete noprompt obsolte;
to
delete noprompt obsolte to device type disk;
2. When using FRA, I can't use FORMAT option as discussed here, irregardless I was happy with the conversion for device type tape BACKUP FULL FILESPERSET 1 FORMAT 'DB%I.%d_%N_%U' DATABASE;. Otherwise, the backupset is written to $ORACLE_HOME/dbs instead FRA location.
