At a high level, seems pretty simple doesn’t it?
Investigating usage for /u01 to free space:
$ df -h /u01 Filesystem Size Used Avail Use% Mounted on /dev/mapper/VGExaDb-LVDbOra1 20G 15G 4.3G 77% /u01
Find five largest directories for u01:
# du -a /u01 | sort -n -r | head -n 5 61379684 /u01 61379660 /u01/app 30698332 /u01/app/oracle 30698308 /u01/app/oracle/product 16096196 /u01/app/18.1.0.0 # du -a /u01/app/oracle/product | sort -n -r | head -n 5 30698308 /u01/app/oracle/product 8913108 /u01/app/oracle/product/12.1.0.2 8913104 /u01/app/oracle/product/12.1.0.2/dbhome_1 8569260 /u01/app/oracle/product/12.2.0.1 8569256 /u01/app/oracle/product/12.2.0.1/dbhome_1
Different versions of unused ORACLE_HOME from u01:
$ ls -l /u01/app/oracle/product drwxrwxr-x 3 grid oinstall 4096 Apr 2 2019 11.2.0.4 drwxrwxr-x 3 grid oinstall 4096 Apr 2 2019 12.1.0.2 drwxrwxr-x 3 grid oinstall 4096 Apr 2 2019 12.2.0.1 drwxrwxr-x 3 grid oinstall 4096 Apr 2 2019 18.1.0.0 drwxr-xr-x 3 oracle oinstall 4096 Apr 3 2019 java
Check inventory and oratab for any reference to u01:
$ grep u01 /u01/app/oraInventory/ContentsXML/inventory.xml home crs='true' /='' loc='/u01/app/18.1.0.0/grid' name='OraGI18Home1' idx='1' type='O' $ grep u01 /etc/oratab +ASM1:/u01/app/18.1.0.0/grid:N # line added by Agent
Check for processes running from specific home:
Note: 11.2.0.4 show process because currently in the directory.
$ pwd /u01/app/oracle/product/11.2.0.4 $ lsof +D /u01/app/oracle/product/11.2.0.4 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME bash 115430 oracle cwd DIR 249,2 4096 524298 /u01/app/oracle/product/11.2.0.4 lsof 172485 oracle cwd DIR 249,2 4096 524298 /u01/app/oracle/product/11.2.0.4 lsof 172488 oracle cwd DIR 249,2 4096 524298 /u01/app/oracle/product/11.2.0.4 $ lsof +D /u02/app/oracle/product/12.2.0/dbhome_5 $ lsof +D /u02/app/oracle/product/12.2.0/dbhome_17 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME oraagent. 273460 oracle mem REG 202,112 1544 25693540 /u02/app/oracle/product/12.2.0/dbhome_17/dbs/hc_DATABASE52.dat oraagent. 273460 oracle 209r REG 202,112 1544 25693540 /u02/app/oracle/product/12.2.0/dbhome_17/dbs/hc_DATABASE52.dat $ cd $ lsof +D /u01/app/oracle/product/11.2.0.4 $
Suddenly, I remembered srvctl config all which I had blogged about.
$ . oraenv <<< +ASM1
ORACLE_SID = [+ASM1] ? The Oracle base has been set to /u01/app/grid
$ srvctl config all

By the way, this is Oracle Database Exadata Cloud Service from what I was informed.
These are actual number of databases.
Looks to be in Phoenix region base on pho suffix in the name?
How does one tell if on cloud or on premise?
My guess is oraclevcn.com from hostname.
