I. Introduction
For one of my banking client, i have developped a shell script to upgrade databases from 12c to 19c, including dataguards & TDE.
The script helped my collegues to upgrade a hundred of production databases, and more in developpment environnement.
The script is based on autougrade.jar oracle binary ....
I also provided a documentation to learn how to use this script ....
Always download the last version of :
AutoUpgrade Tool (Doc ID 2485457.1)
II. Upgrade Mode
I relied on the two modes of autoupgrade.jar : ANALYZE & DEPLOY.
So my script uses also these two modes ...
III. ANALYZE Mode
|
On the Primary database:
o Ask the DBA if he has a Full backup, with a minimum verification of a Full backup less than 7 days old o Primary Instance: All PDBs must be in OPEN and NOT RESTRICTED state: it outputs an error otherwise o Check the status of the broker if Dataguard: it outputs an error if the broker is not valid o Check that at least 75% of the FRA is not used : it outputs an error otherwise o If Dataguard, ask the DBA to launch this script in ANALYZE mode on the Standby o Analyze the database: preCheck and PostCheck recommendations o A table will summarize the number of errors, warnings and Recommendations On the Standby bases: o Check the status of the broker if Dataguard: it outputs an error if the broker is not valid o Check that at least 75% of the FRA is not used (in case of ARCHIVELOG): it outputs an error otherwise o Others checks .... |
The script checks this status ...
|
the script must be lauched : - First on the database server - Next on the standby server (if exists) |
upgrade.sh -s MYDATABASE -m ANALYZE
The output is :

some outputs :

At the end, status of the ANALYZE mode : 2 cases :
Case 1 : Failed status 2022/05/25 11:59:51 - INFO - Summarize ANALYZE Mode : MODE : ANALYZE ERRORS : 2 WARNINGS : 18 RECOMMEND : 14
Case 2 : Success status 2022/05/25 11:59:51 - INFO - Bilan ANALYZE Mode : MODE : ANALYZE ERRORS : 0 WARNINGS : 18 RECOMMEND : 14 |
IV. DEPLOY Mode
First : the ANALYZE mode must be in Success status.
The script checks this status ...
|
the script must be lauched : - First on the database server - Next on the standby server (if exists) |
upgrade.sh -s MYDATABASE -m DEPLOY
The output is :
