Services in RAC environment
Hi all,
i hope is the correct subforum...
i'm having some trouble in demo machine given us by an hardware vendor.
environment is a 2 nodes RAC 11.1.0.7 on windows server 2008 (sic!)
installation successful of clusterware and database.
Application created successufully
i need to create some services and here start the mess...
when i try to creat service ADMIN i ask to modify tnsnames as well and this happens but when i try to connect user@service instead of user@SID i receive:
ORA-12514 TNS:listener does not currently know of service requested in connect descriptor
so i tried to see if tensnames/sqlnet/listener were correct and all infos are ok but if i try to check listener status i just can see handles for database, instances and asm instances...
none of the services i registered is present...
i tried to reload, to stop and start listener...no news...
any suggestion??
thanks in advance ad sorry for my poor english
Surachart, i'm in windows 2k8 environment so grep doesn't work...
i did lsnrctl service and lsnrctl status check but both shows only global database name and single instances entry plus asm and _xpt and dispatcher...
here is LSNRCTL status

Instnce name in non-RAC environment
Hi!
In non-RAC environment V$INSTANCE.INSTANCE_NAME does not actually displays the name of the instance,that was set in INSTANCE_NAME parameter.
It always displays DB_NAME instead.
Is it any way to get instance_name that has service user connected to in this environment?

The documentation on INSTANCE_NAME in the 10gR2 Reference says :
"In a single-instance database system, the instance name is usually the same as the database name."
(this after
"In a Real Application Clusters environment, multiple instances can be associated with a single database service. Clients can override Oracle's connection load balancing by specifying a particular instance by which to connect to the database. INSTANCE_NAME specifies the unique name of this instance.")
This would imply that setting INSTANCE_NAME in non-RAC is ignored. The usage of the word "usually" is weak.

DBMS_SCHEDULER behavior in a RAC environment
What is the behavior of DBMS_SCHEDULER in a RAC environment (say 2 nodes, N1 and N2):
Is the behavior of a DBMS_SCHEDULER job created using a connection to the RAC service name be the same as if the job were created using a connection to N1 iusing the SID of N1?
If multiple jobs are created at N1 using the SID in the connection, will the RAC environment manage these in parallel across N1 and N2?
Thanks.Hi,
Is the behavior of a DBMS_SCHEDULER job created using
a connection to the RAC service name be the same as
if the job were created using a connection to N1
iusing the SID of N1?Yes there is no difference.
If multiple jobs are created at N1 using the SID in
the connection, will the RAC environment manage these
in parallel across N1 and N2?Yes. However, jobs have a slight preference to run on the instance they ran on previously (for performance reasons due to caching). So if both nodes are lightly loaded then a job will stick to running on the node it ran on the first time. However if that node gets loaded the Scheduler will start running the job on the other node (i.e. simple load-balancing) .
Thanks,
Ravi. -
Genclntst fail in oracle10g RAC environment
After installation of oracle 10gR2 RAC on two-node solaris10 environment ,we need to run $ORACLE_HOME/bin/genclntst to generate the Client Static Library(libclntst10.a) but it failed .We copy another successfully generated libclntst10.a file from a non-RAC oracle10g environment running on solaris10.
and it seems to work correctly. is it really OK ?,is there any difference between the libclntst10.a file in a RAC environment and in a non-RAC environment ?
thanks a lot.

In 11g you can use the instance_id job attribute to do this.
In 10g you can do this using services.
- create a service for each instance
- create a job class pointing to each service
- grant execute on the job classes to all job owners that need to use them
- when creating a job point to the job class for the service for the instance it should run on
Oracle recommends using services instead of instances since services are more flexible and can provide high-availability and fail-over in case one instance goes down.
Hope this helps,

Cssd does not start in non-RAC environment Thus we can not bring up ASM
Non-RAC environment
ASM version = 11.1.0.7
HP-UX Itanium 11.23
After power outage, CSSD does not start on non-RAC environment
Running as root "/sbin/init.d/init.cssd start" does not start cssd
Oracle support tried "$ASM_HOME/bin/localconfig delete" and "$ASM_HOME/bin/localconfig add"
but it did not start CSS
Oracle support tried "$ASM_HOME/bin/localconfig reset $ASM_HOME"
It started the CSSD and the "crsctl check css" came back with CSS is healthy
But around 1 minute later it rebooted the server and when it came up again CSS does not start.
They checked /etc/inittab and it looked fine.
Before the reboot we saw this message in the /var/adm/syslog/OLDsyslog.log:
Cluster Ready Services completed waiting on dependencies
Again it is a NON-RAC environment. We only need CSSD for ASM. We do not have CRS installed on this server.
Our test system has been down for a week and we did not get the resolution from Oracle support yet !
Any pointers are greately appriciated.
Thanks,

Are multiple PHYSICAL databases supported in one Oracle 10g RAC environment
Hi alls,
as of Metalink 220970.1 Oracle RAC is also supporting different databases in one cluster installation. RAC handles any resource as a service and it doesn't matter if these services belongs to only one or to different databases. You install the Oracle Clusterware only once and you create any service you want to make high available.
So is technically possible to install multiple databases on same Oracle Rac environment.
My doubts are related to SAP , does SAP certify such environments ?? we could have one SAP R/3 database and SAP BW database co-exist in a single Oracle RAC environment. or also co-exist SAP database with a non-SAP database (an already existing application) in the same Oracle Rac environment.
Any comment would be higly appreciated.
Silvio BrandaniWe have ECC, BI, PI and Portal running on same Oracle RAC environment. We have one RAC for QA systems and one for PRD systems. We are not running any SAP applications along with Non-SAP applications on RAC. Keeping SAP and non-SAP apps separate would be a way to go.
Hope this helps.
Thanks,

How to change DB name and SID in RAC environment?
I have 2 node RAC on Red Hat Linux, EL 4, upd. 4. It's using ASM
and it is working great. However, after 2 years of faithful service
I was asked to change DB name and SID. In non-RAC environment, that is
easy. Rename a few files, change init.ora and re-create control file.
I've done that many times. With 10g RAC, however, situation is different. There is also RAC registry which has the database under the certain name and, I believe, it also has SID registered. Can you, please, point me to a document describing how to do that? It's a production DB and I can't test it anywhere.It's in the manual:

Steps to do switchover / switchback in RAC environment
Hi folks,
I m having setup with 2 node RAC primary and 2 node RAC Dataguard on 10.2.0.4.0. Dataguard setup is working fine. Dataguard is setup with Standby Redo log group with managed recovery. There is no problem with transferring archives & applying on standby.
Now I want to do Switchover/Switchback between Primary and Standby for RAC. I am familiar with Single instance Switchover and Switchback but never did RAC environment Switchover/Switchback. Can anybody please elaborate steps or suggest any link for me??
regards,
manishHi Guys,
Today I performed RAC Switchover / Switchback for 2 Node Primary with 2 Node Standby on OEL. I expected some issues, but it was totally smooth. Giving you steps for the same, so it will be useful to you. Even this would be my first contribution to Oracle Forums.
DB Name DB Unique Name Host Name Instance Name
live live linux1 live1
live live linux2 live2
live livestdby linux3 livestdby1
live livestdby linux4 livestdby2
Verify that each database is properly configured for the role it is about to assume and the standby database is in mounted state.
(Verify all Dataguard parameters on each node for Primary & Standby)
Like,
Log_archive_dest_1
Log_archive_dest_2
Log_archive_dest_state_1
Log_archive_dest_state_2
Fal_client
Fal_server
Local_listener
Remote_listener
Standby_archive_Dest
Standby_archive_management
service_names
db_unique_name
instance_name
db_file_name_convert
log_file_name_convert
Verify that both Primary RAC & Dataguard RAC are functioning properly and both are in Sync
On Primary,
Select thread#,max(sequence#) from v$archived_log group by thread#;
On Standby,
Select thread#,max(sequence#) from v$log_history group by thread#;
Before performing a switchover from a RAC primary shut down all but one primary instance (they can be restarted after the switchover has completed).
./srvctl stop instance –d live –i live1
Before performing a switchover or a failover to a RAC standby shut down all but one standby instance (they can be restarted after the role transition has completed).
./srvctl stop instance –d live –i livestdby1
On the primary database initiate the switchover:
alter database commit to switchover to physical standby with session shutdown;
Shutdown former Primary database & Startup in Mount State.
Shut immediate;
Startup mount;
select name,db_unique_name, log_mode,open_mode,controlfile_type,switchover_status,database_role from v$database;
Make log_Archive_Dest_state_2 to DEFER
alter system set log_archive_dest_state_2='DEFER' sid='*';
On the (old) standby database,
select name,log_mode,open_mode,controlfile_type,switchover_status,database_role from v$database;
On the (old) standby database switch to new primary role:
alter database commit to switchover to primary;
shut immediate;
startup;
On new Primary database,
select name,log_mode,open_mode,controlfile_type,switchover_status,database_role from v$database;
Make log_Archive_Dest_state_2 to ENABLE
alter system set log_archive_dest_state_2='ENABLE' sid='*';
Add tempfiles in New Primary database.
Do some archivelog switches on new primary database & verify that archives are getting transferred to Standby database.
On new primary,
select error from v$archive_Dest_status;
select max(sequence#) from v$archived_log;
On new Standby, Start Redo Apply
alter database recover managed standby database using current logfile disconnect;
Select max(sequence#) from v$log_history; (should be matching with Primary)
Now Start RAC databases services (both Primary – in open & Standby – in mount)
On new Primary Server.
./srvctl start instance –d live –i livestdby2
Verify using ./crs_stat –t
Check that database is opened in R/W mode.
On new Standby Server.
./srvctl start instance –d live –i live2 –o mount
Now add TAF services on new Primary (former Standby) Server.
By Command Prompt,
./srvctl add service -d live -s srvc_livestdby -r livestdby1,livestdby2 -P BASIC
OR
By GUI,
dbca -> Oracle Read Application Cluster database -> Service Management -> select database -> add services, details (Preferred / Available), TAF Policy (Basic / Preconnect) - > Finish
Start the services,
./srvctl start service -d live
Verify the same,
./crs_stat -t
Perform TAF testing, to make sure Load Balancing & Failover.
regards,
manish

How to create DIR/File on a raw device in RAC environment.
Hi all,
I use a shell script to create DIR and File on a raw device also it creates schema and tablespaces.
I am facing problem in creating DIR and Files on raw device.
One more thing, can multiple tablespaces be created on a raw device.
Thanks & regards,
SanjeevThanks for the response. Please help me further.
About the Script - It asks for the path for creating DIR and uses shell command to create DIR. Later same path and DIR name is used to create Oracle DIR. Now in place of absolute path raw device name is passed. The same script is also used for creating tablespaces and schema.
There is second script that is .sql script that creates external table in the newly created schema. All this has been working fine on single instance Oracle server. we have tested many times but fails in RAC environment when we use raw device.
Question is - If I use filesystem will the external table's flat files and Directories be accessible to all the instances.
I have one application written in java that would be clustered and running on these oracle servers. This application would be accessing those external tables and their flat files. Will there be a problem accessing these flat files accross the instances.
Regards,
Sanjeev. -
Calculating total memory in oracle RAC environment
I have to calculate total memry in RAC environment.
For shared and buffer pool I execute show sga.
For UGA and PGA I execute statement that have two different values.
This is my two different methot for calculating total memory in oracle RAC environment.
Why I have very different value in this 2 statements on pga values?

where ss.sid = s.sid
and ss.inst_id = s.inst_id
and ss.statistic# = 15) session_uga_memory
from gv$session s)
union all
select 'SGA: ' || name pid
,s.inst_id iid

,p.pga_alloc_mem bytes
from gv$session s
,gv$sesstat pcur
,gv$process p
where pcur.statistic# in ( 20 -- = session pga memory
,15 -- = session uga memory
and s.paddr = p.addr
and pcur.sid = s.sid
and pcur.INST_ID = s.INST_ID
and pcur.INST_ID = p.INST_ID
union all

2 SGA: Variable Size 335544320I'm sorry but it is not clear to me.
- From v$session (1th stmt) I have
nearly 196MB of PGA mem on instance 1
and
nearly 77MB of PGA mem on instance 2
- From v$process (2th stmt) I have
nearly 342MB of PGA mem on instance 1
and
nearly 186MB of PGA mem on instance 2
then...
342+186 - 196+77 = nearly 255MB of memory allocated by oracle processes but free?
if I want calculate the total thing of the amount of the allocated memory from Oracle...It is more correct 2th statement that query v$process...it is true? -
IS IT SUPPORTED TO CENTRALLY MOUNT THE ORACLE_HOME IN A NON-RAC ENVIRONMENT
SR 7250090.993 : (http://qmon.oraclecorp.com/qmon3/quickpicks.pl?t=t&q=7250090.993)
Technical Summary:
Customer is planing to install Oracle 10.2.0.4 and 11.1.0.x software on a Red Hat5 with NetApp storage.
Customer came across the following :
For single instance installations (as opposed to RAC installations), you must create a separate Oracle home directory for each installation. Run the software in this Oracle home directory only from the system that you used to install it. For Oracle Real Application Clusters (RAC) installations, you can use a single Oracle home directory mounted from each node in the cluster. You must mount this Oracle home directory on each node so that it has the same directory path on all nodes.
mentioned in the 10gR2 documentation link :
http://download.oracle.com/docs/cd/B19306_01/install.102/b15667/app_nas.htm#BCFIDEJA
Requirements/Expectations:
As the above statements, that customer came across is not present in 9i documentation, customer wants to understand if it is actually supported to centrally mount the 10g/11g ORACLE_HOME to many servers that are not RAC enabled.
Also, I would like to understand if the statements in documentation indicate that it is not generally recommended centrally mount the 10g/11g ORACLE_HOME or does it mean that it is not supported to centrally mount the ORACLE_HOME in a non RAC environment?
Please advice.The binaries (executables) in an Oracle home are "linked" (link edited?) to the OS libraries on each server where the software is installed.
Unless the OS is IDENTICAL on each of the IDENTICAL(HW) servers -- that would share the Oracle home--, you could be in trouble.
The only supported configuration (I know of) where the Oracle binaries are shared between servers is 9i RAC. On 10g RAC the binaries are installed on each server.
Other wise I'd say it's NOT recommended, besides you don't save anything (execpt a cooupl of Gigs disk space).
:p -
Gurus,
what are the advantages, if any, of running ASM in a non-RAC environment?
Thanks.Any raid (that actually provides multiple disks in a
LVM) will nullify the performance gains of raw that
are associated with disk head contention.
Any disk subsystem with front-end RAM cache will
nullify the rest of the performance gains of raw
disk.
Any 'RAID-5 is good' argument under a database
assumes large and efficient cache.Unfortunately, we can't just discount RAID-5, since it is far too cost-efficient an option these days, with 10, 20, 30+ TB databases. Plus, the storage vendors actually make it efficient enough that it performs almost as well as RAID 1+0.
Multiple disks on the storage subsystem and RAM caches (for reads and writes) are still important and valuable performance enhancements. Remember that your storage subsystem is much more efficient at this than your database or server (since it's designed to do it!). True, it doesn't have knowledge of the database files, their content, and their usage, but you do, and can therefore intelligently configure the subsystem and place the data files.
ASM does nothing more intelligent than stripe the data across all of the available disks. The best part about it is the ability to dynamically grow the groups. The problem with it is that it thwarts the read-ahead cache of the storage subsystem. And, while Oracle will intelligently 'read-ahead', it can't optimize where the heads are on the disk, or take into consideration the 10 other servers accessing the same storage subsystem.
The problem with ASM doing the striping is that, for large databases, you will typically have hundreds of disks underneath the covers. If you gave the OS and then Oracle that many devices, what do you think would happen? It would step all over itself and seriously impair your ability to access the devices in parallel. Whereas, if you group 4 or 8 devices together, the storage subsystem will access them together in parallel for the OS.
So, don't discount your storage box... But yeah, use RAID 1+0 rather than RAID-5 (4,3) when possible! -
Analyze job very slow in RAC environment
Hi,
I have an anlyze job which runs for 3 hrs in RAC environment (9.2.0.6).
Earlier in NON-RAC environment it used to complete in 1 hrs.
Need help in solving this issue.
Ajoy Kumar Thapahi,
This database is used for query purpose mainly.
we do huge data load during weekend into one of the table.
This table is then exchange with one of the partition of a huge partitioned table.
after that analyze job runs on this partitioned table.
The command we use for analyze is given below:
DBMS_STATS.GATHER_SCHEMA_STATS
ownname => '<owner_name>'
,estimate_percent => 05
,cascade => true
,degree => 4
,granularity=>'ALL'
I want to know, what can be the reason, this job, which runs fine in NON-RAC environment, is taking so long in RAC enviroment.
Any help is highly appreciated.
