RAC & Failsafe :: Query On Dependency Between Database Instance And Service?
Jul 8, 2013
suggest on the dependenecy between the database service and the database instance?
srvctl start instance -i db1
will this start service as well for which the above instance is either preferred or available instance?
will it start the listener as well?
srvctl stop instance -i db1
will this stop service as well for which the above instance is either preferred or available instance?
will it stop the listener as well?
srvctl start service -d db -s dbserve
will this start service as well for which the above instance is either preferred or available instance?
srvctl stop servive -d db -s dbserve
will this stop service as well for which the above instance is either preferred or available instance?
srvctl start database -d db
will it start instance, listener and service as well?
srvctl stop database -d db

i have 2 nodes RAC with service piodbserv2 which is active only on 2nd node. client is connected for (100% sure) to piodbserv2 on node2. i am doing relocation of this service to node1 using -f (force) option:
[oracle@rac1 ~]$ srvctl relocate service -d piodb -s piodbserv2 -i piodb2 -t piodb1 -f
[oracle@rac1 ~]$ srvctl start service -d piodb -s piodbserv2 -i piodb1
PRKP-1064 : Service piodbserv2 is already running on instance piodb1.
[oracle@rac1 ~]$ srvctl start service -d piodb -s piodbserv2 -i piodb2
-f (force) option is described as this which forcibly rellocate users from one to another node simply disconnecting sessions from node2 in my example
but i am surprised because my session is still opened on node2 after piodbserv2 relocation
SQL> select sys_context('userenv','instance') from dual;
SYS_CONTEXT('USERENV','INSTANCE')
-------------------------------------------------------------
2
SQL> select sys_context('userenv','instance') from dual;
SYS_CONTEXT('USERENV','INSTANCE')
-------------------------------------------------------------
2
SQL> select instance_number from v$instance;
INSTANCE_NUMBER
---------------
2
SQL>
at this moment piodbserv2 is only on node2. when i kill my user session and try connect again it will connect to node1. but i suspected that after forcibly rellocated service, my sessions will be disconnected from node2 forcibly also.

While doing this activity i have stop all CRS and DB services. As usual i have did same in both the nodes and applied the patch and reboot the server.
After tried to start the CRS service and database services was used the following command. Except node1 instances all services are started.

I need to interchange the value which has foreign key depednecy,
For ex: I have a table dept
deptno| dname|dseq|
10 | CS | 1
20 | SC | 2
and in emp table
eno | ename | deptno |
1 |Raj | 10 |
2 |Ram | 10 |
3 |Vip | 10 |
4 |Muk | 10 |
5 |Sn | 20 |
6 |Snj | 20 |
7 |Asj | 20 |
there is a forign key define :
ALTER TABLE emp ADD (
CONSTRAINT rop_fk
FOREIGN KEY (deptno)
REFERENCES dept (deptno));
Now I want to change the deptno from 10 to 20 and 20 to 10 in dept table . So the ouput will be like
deptno| dname|dseq|
20 | CS | 1
10 | SC | 2
when i am deleting that row I am getting error "ORA-02292: integrity constraint (ROP_FK) violated - child record found".IF i am trying to update i am getting unique key contractin failure.
(Even I cannot update the rest of the column values in dept table as it is also having foreign key dependency) i need to put a sql script in production so that it will interchange.

I want to find role dependency on another role.
1. If its a basic role (made of priviliges), what data dictionary view I should query?
2. If the role is made of some other role and additional priviliges, what query I should fire to find that?
3. Role is granted to which users?

While there's numerous QAs about inserting an image into the DB using the Data Block, how does one remove an image? Obviously there's the "UPDATE ... SET X = EMPTY_BLOB();", however, that kills the Data Block/Form's flow, and it doesn't update.
I've tried a few things:
* :CONTROL.IMG1 := NULL; (bad bind variable)
* :CONTROL.IMG1 := EMPTY_BLOB(); (some other error, probably as above)

the literature equates dimension hierarchies with fuctional dependencies between the levels. I like to tst the strength of this assumption with the implementation of 'CREATE DIMENSION' which allows you to create roll-up hierarchies.
My question to put it simply is this: Given:
CREATE DIMENSION location_dim
LEVEL location IS (location.loc_id)
LEVEL city IS (location.city)
LEVEL state IS (location.state)
HIERARCHY geog_rollup (
location CHILD OF
city CHILD OF
state CHILD
)
Can I insert the following rows into the dimension:
loc_id, city, state
1, Epping, NSW
2, Epping, VIC
Please note that the two Eppings are different cities.
Given the roll-up hierarchy City -> State, will it require that for every city there can be only one state in which case the FD between City and State cannot hold. Or, is it that the roll-up hierarchy defined here has nothing to do with FD.
The second part of the question is if the answer to the above question is that the roll-up is not the same as FD, then is the ATTRIBUTE clause meant to define the n:1 (functional dependency) instead?

create a new DB service and apply the load , then I need to verify the service load from Enterprise Manager or table V$SERVICEMETRIC .
Below are what I did
Quote:I tried to add service in tnsnames.ora like below
SERVICE = (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(PORT=25057)(HOST=dadvmc))(CONNECT_DATA=(SID=tgc4)))
/************
Also I tried the serviceName like below, but not working when I conneted SALES1 from sqlplus
SALES1 = (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(PORT=25057)(HOST=dadvmc))(CONNECT_DATA=(SERVICE_NAME=host.us.xxx.com)))
**********/
and login as
sqlplus scott/tiger@SERVICE[/email][/email]
then lock table EMP in exclusive mode in two session.
I can see the load is added to service SYS$USERS , but I can't see the new service from V$SERVICEMETRIC or Enterprise Manager.
select
SERVICE_NAME
from V$SERVICEMETRIC
How could we create the new DB service?

It's been a while since I worked with SQL Plus . I am using Oracle 11g. We are working on a legacy data migration project. I have a table of records with circular dependency records. i am trying to identify the records. I have the foll. columns- Product,Source,target. I want o identify the records which form a loop. For e.g.
Source Target
A B
B C
C D
D A
Last record forms a loop-I need to identify these records. My query is below-
SELECT DISTINCT SOURCE,TARGET FROM RULESELIB WHERE CONNECT_BY_ISCYCLE=1 CONNECT BY NOCYCLE SOURCE=PRIOR TARGET;
I ran this query on 2 tables- one with 75000 records and the other with 25000 records. It works fine on the table with 75000 records completes within a minute but it does not complete on the other table. I can't seem to be able to figure out the issue with the query or is there something about the data that is causing this query to loop infinitely?

I cant able to connect to my local DB instance. Oracle service for DB instance will be started running when the system boots automatically.I faced this problem before, I was instructed to boot my system without network connection. It worked for few days. Suddenly I cant able to connect to my local DB instance again, even though I am booting my system without network connection.
This is the configuration I have in tnsnames.ora in my local machine.I have the host as localhost, because local machine is laptop and IP will change periodically.

My context on our servers is the following one:
- one ASM instance
- X DB instances
- each DB instance uses 2 or more dedicated diskgroups from the ASM instance
- there is one diskgroup named FREEDISK that contains spare disks
On each DB instance you can see:
- the list and global parameters of all diskgroups using v$asm_diskgroup view
- the list and parameters of all disks the instance is using with v$asm_disk view
So my question is: how (if this is possible) to know the list of (spare) disks in FREE DISK disk group?
