Services [not] Starting Automatically with CRS after Reboot

Hello all!
So, these days a client asked me to check why his database was not starting with CRS after reboot. So I started investigating and noticed this…

On Oracle 11.2, the database auto start policy in the clusterware is restore, which means that clusterware will remember the last state of the database. As well as database, Oracle 11.2 comes by default with several important resources with attribute AUTO_START=restore in the profile.

With that, if the database was stopped normally then on the next restart of clusterware it won’t be started. Otherwise if the server crashes or by some reason the OS is rebooted then clusterware will start the database because last state was ONLINE (running).

In my case, a second reboot was done with database down, and this is why database didn’t started. And same applied to some other target types.

The conclusion I get?
For best availability, it is a good practice to change this default behaviour after each installation on 11.2. Some checking and adjusting scripts below:

To check all Resources:

crsctl stat res -p

Checking on database resource:

...
NAME=ora.grepora.db
TYPE=ora.database.type
ACL=owner:oracle:rwx,pgrp:oinstall:rwx,other::r--
ACTION_FAILURE_TEMPLATE=
ACTION_SCRIPT=
ACTIVE_PLACEMENT=1
AGENT_FILENAME=%CRS_HOME%/bin/oraagent%CRS_EXE_SUFFIX%
AUTO_START=restore
...

But besides DB, several resources were in restore or even in never, like ASM and Voting Disk DG… Check for all resourced AUTO_START:

[root@greporasrv1 ~]# crsctl stat res -p |grep AUTO_START
AUTO_START=always
AUTO_START=always
AUTO_START=always
AUTO_START=restore
AUTO_START=restore
AUTO_START=restore
AUTO_START=restore
AUTO_START=never
AUTO_START=never
AUTO_START=restore
AUTO_START=always
AUTO_START=restore
AUTO_START=restore
AUTO_START=restore
AUTO_START=restore
AUTO_START=restore
AUTO_START=always
AUTO_START=restore
AUTO_START=restore
AUTO_START=restore
AUTO_START=restore

Well, so to fix all the resources:

crsctl modify resource ora.APS1.dg -attr AUTO_START=always
crsctl modify resource ora.DG1.dg -attr AUTO_START=always
crsctl modify resource ora.FRA.dg -attr AUTO_START=always
crsctl modify resource ora.LISTENER.lsnr -attr AUTO_START=always
crsctl modify resource ora.VDISK_OCR.dg -attr AUTO_START=always
crsctl modify resource ora.asm -attr AUTO_START=always
crsctl modify resource ora.gsd -attr AUTO_START=always
crsctl modify resource ora.net1.network -attr AUTO_START=always
crsctl modify resource ora.ons -attr AUTO_START=always
crsctl modify resource ora.registry.acfs -attr AUTO_START=always
crsctl modify resource ora.LISTENER_SCAN1.lsnr -attr AUTO_START=always
crsctl modify resource ora.LISTENER_SCAN2.lsnr -attr AUTO_START=always
crsctl modify resource ora.LISTENER_SCAN3.lsnr -attr AUTO_START=always
crsctl modify resource ora.cvu -attr AUTO_START=always
crsctl modify resource ora.grepora.db -attr AUTO_START=always
crsctl modify resource ora.greporasrv1.vip -attr AUTO_START=always
crsctl modify resource ora.greporasrv2.vip -attr AUTO_START=always
crsctl modify resource ora.oc4j -attr AUTO_START=always
crsctl modify resource ora.scan1.vip -attr AUTO_START=always
crsctl modify resource ora.scan2.vip -attr AUTO_START=always
crsctl modify resource ora.scan3.vip -attr AUTO_START=always

Below the output and the checking:

Shellscript: Which database is this service_name from?

Hey!
Strange question, right? You should know you applications and databases and how everything works, right?

Happen that some days ago a client requested me to identify from which database is a service_name. Easy? Not if the server have 46 database instances running…

Ok, now how can I can this information as quick as possible?

I know that the command below give me all distinct databases in CRS:

/u01/app/12.1.0.2/grid/bin/crsctl stat res -t -w "TYPE = ora.database.type"

Now, lets make some sed magic:

[root@nprd01dbadm01 ~]# /u01/app/12.1.0.2/grid/bin/crsctl stat res -t -w "TYPE = ora.database.type" |grep ora. |sed 's/ora./srvctl status service -d /' |sed 's/.db/ |grep \$1/' | head -1
srvctl status service -d dba |grep $1

CRSCTL: AUTO_START of Cluster Services (ACFS)

As I sad long time ago (Manually Mounting ACFS)… Here is it:

To set autostart of a resource (in my case an ACFS) by CRSCTL, here the simple example:

# Check How it is currently configured:

[root@db1database1p bin]# ./crs_stat -p ora.dghome.dbhome.acfs |grep AUTO_START
AUTO_START=restore

# Set Autostart (and check):

[root@db1database1p bin]# ./crsctl modify resource ora.dghome.dbhome.acfs -attr AUTO_START=always
[root@db1database1p bin]# ./crs_stat -p ora.dghome.dbhome.acfs |grep AUTO_START
AUTO_START=always

It can be done also with “AUTO_START=1”. We have 3 possibilities (always, restore and never).

Service Detected on OEM but not in SRVCTL or SERVICE_NAMES Parameter?

Okey, it happens.
To me, after a database moving from a cluster to another. The service was registered by SRVCTL in the old cluster but is not needed. So, was not registered in the new cluster.
But OEM insists to list, for example, the “service3” as offline. The problem is that you can not remove it by SRVCTL, because you had not registered, right? See the example below:

Listing services:
srvdatabase1:/home/oracle>srvctl status service -d systemdb
Service service1_systemdb is running on nodes: srvdatabase1
Service service2 is running on nodes: srvdatabase1
Service service2_systemdb is running on nodes: srvdatabase1

In the service_name parameter:
srvdatabase1:/home/oracle>sqlplus / as sysdba

And the offline alarm goes to “service3“?
The easiest fix:

SQL> exec dbms_service.DELETE_SERVICE('service3');
