use SQLcl with EZconnect and multiple hostnames (ADDRESS_LIST=)

Question

this is our classic tnsnames.ora

test1=
(DESCRIPTION=
    (CONNECT_TIMEOUT=4)
    (TRANSPORT_CONNECT_TIMEOUT=3)
    (ENABLE=BROKEN)
    (ADDRESS_LIST=
        (ADDRESS=(PROTOCOL=TCP)(HOST=example1.example.com)(PORT=1521))
        (ADDRESS=(PROTOCOL=TCP)(HOST=example2.example.com)(PORT=1521))
    )
    (CONNECT_DATA=
        (SERVER=DEDICATED)
        (SERVICE_NAME=EXAMPLE.EXAMPLE.DBS)
    )
)

I use this SQLcl command:

sql -nohistory -noupdates -S $username/$password@$hostname:$port/$servicename @$filename

How to specifiy multiple hostnames? Not only one? It's some kind of active passive cluster (Exadata).

Edit after first answer:

I added in shell script (in this dir tnsnames.ora):

TNS_ADMIN=/example/example

I call $sqlcl -nohistory -noupdates -S $username/$password@"MY-DB" @$filename and get back the error:

./script.sh
  USER          = MY_USER
  URL           = jdbc:oracle:thin:@MY-DB
  Error Message = IO Error: Unknown host specified
  USER          = MY_USER
  URL           = jdbc:oracle:thin:@MY-DB:1521/MY-DB
  Error Message = IO Error: Invalid connection string format, a valid format is: "host:port:sid"

EZconnect was not meant for things like that.

SQLcl can use tnsnames.ora as well. Just create one and use it:

sql -nohistory -noupdates -S $username/$password@test1 ...

Or you can do this, if you really want to provide all that stuff as a commandline argument:

sql -nohistory -noupdates -S $username/$password@"(DESCRIPTION= (CONNECT_TIMEOUT=4) (TRANSPORT_CONNECT_TIMEOUT=3) (ENABLE=BROKEN) (ADDRESS_LIST= (ADDRESS=(PROTOCOL=TCP)(HOST=example1.example.com)(PORT=1521)) (ADDRESS=(PROTOCOL=TCP)(HOST=example2.example.com)(PORT=1521))) (CONNECT_DATA= (SERVER=DEDICATED) (SERVICE_NAME=EXAMPLE.EXAMPLE.DBS)))" ...

Using tnsnames.ora:

[oracle@o71 ~]$ export JAVA_HOME=/u01/app/oracle/product/19.0.0/dbhome_1/jdk
[oracle@o71 ~]$ export PATH=/home/oracle/sqlcl/bin:$JAVA_HOME/bin:$PATH
[oracle@o71 ~]$ export TNS_ADMIN=/u01/app/oracle/product/19.0.0/dbhome_1/network/admin
[oracle@o71 ~]$ cat /u01/app/oracle/product/19.0.0/dbhome_1/network/admin/tnsnames.ora
MIN19=
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.71)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME =  min19_o71)
    )
  )

[oracle@o71 ~]$ sql bp/bp@min19
