TCPS configuration: ora.LISTENER.lsnr is in INTERMEDIATE state

Problem

After configuring TCPS endpoint in listener configuration using the following way:

In srvctl:

[grid@rac1 ~]$ srvctl modify listener -p "TCP:1522/TCPS:1524"

In listener.ora file:

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = rac1.example.com)(PORT = 1522))
      (ADDRESS = (PROTOCOL = IPC)(KEY = LISTENER))
      (ADDRESS = (PROTOCOL = TCPS)(HOST =rac1.example.com)(PORT = 1524))
    ))

So from the above, we see that I’ve configured as static endpoint registration as well as dynamic.

Restarted listener and saw that ora.LISTENER.lsnr resource left in the INTERMEDIATE state:

# srvctl stop listener;srvctl start listener

# crsctl status res -t|head
...
ora.LISTENER.lsnr 
ONLINE INTERMEDIATE rac1 Not All Endpoints Registered,STABLE
ONLINE INTERMEDIATE rac2 Not All Endpoints Registered,STABLE

Troubelshooting

After checking listener.log file, found the following messages:

Dynamic address is already listened on (DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=rac1.example.com)(PORT=1524)))
Dynamic address is already listened on (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=rac1.example.com)(PORT=1522)))
Dynamic address is already listened on (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=rac1.example.com)(PORT=1522)))

So, due to the static registration, the dynamic failed and Agent thought it could not register endpoints, which left resource in the INTERMEDIATE state (which should not be normal I think) 

I tried to disable dynamic registration by setting ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER to OFF in listener.ora file, but after modifying and restarting listener using srvctl Oracle Agent changed the value back to ON. I could not find a way to disable it so far.

The second option was to remove static entries from listener.ora file and leave only dynamic registration, but after that, the important endpoint on TCPS/1524 was not registered:

(DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=LISTENER)))
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=192.168.1.11)(PORT=1524)))
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.1)(PORT=1522)))
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.11)(PORT=1522)))

The endpoint that I want is 192.168.1.1:1524 and not 192.168.1.11:1524

Workaround

Configured dynamic registration in srvctl for TCP/1522 port only:

[grid@rac1 ~]$ srvctl modify listener -p "TCP:1522"

Configured static registration in listener.ora file for TCPS/1524:

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = LISTENER))
      (ADDRESS = (PROTOCOL = TCPS)(HOST =rac1.example.com)(PORT = 1524))
    )
  )

After restarting listener, the status became ONLINE:

ora.LISTENER.lsnr
              ONLINE  ONLINE   rac1   STABLE
              ONLINE  ONLINE   rac2   STABLE

Another workaround that my colleage found is the following:

Set ENDPOINTS to null in crsctl (in srvctl it’s not possible):

# crsctl modify resource ora.LISTENER.lsnr -attr "ENDPOINTS=" –unsupported

And register all endpoints statically in listener.ora. Using that way, no dynamic registration is triggered, only static endpoints will be visible.

Please comment bellow, if you have a better way. Thank you!
