Can there be multiple ASM instances on single node?

Hi,
Can there be multiple ASM instances on single node?
This one says No : http://www.freelists.org/archives/oracle-l/02-2008/msg00317.html
And This one says Yes : http://www.databasejournal.com/features/oracle/article.php/3571371
Thanks in advance.

...that document doesnt say you cannot have multiple ASM instances on a node. It says "...ASM, +you only need one ASM+ instance for that computer, to manage the two database instances that use ASM."
The fact that you only need one - and I cannot think of a good reason to have more than one - does not preclude the fact that you do seem to be able to have multiple ASM instances on a single node, each looking after its own set of disks and diskgroups.
Again - I cannot think of a good reason to do so though!

Install RAC OBS on single node using VMWare

Re: How to install Muti_node R12 using VMWARE
Mine is a little different.
I have the Test server which has OEL5 and one OAS 10g(Oracle application Server) with 10g database.
I want to install RAC OBS on this server by installing VMWare for the single node. I do not want to wipe out the OAS, reinstore OSL5 and start from a blank machine.
Can I keep what I have on the server and install RAC OBS by installing VMWare, configuring the virtual sharing disks, and install RAC OBS using ASM?

Hi,
Can I keep what I have on the server and install RAC OBS by installing VMWare, configuring the virtual sharing disks, and install RAC OBS using ASM?Yes, you can. Just make sure you have sufficient resources on this machine.

Multiple ASM Instances on single node

Hi All,
After going through some threads it seems to me that multiple ASM instances on a node is not supported and recommended by ORACLE but i coudn't find any ORACLE document or support matrix mentioning this. Can any one give me a pointer to this. Please correct me if i am wrong and Multiple ASM instances are fully supported by ORACLE.
Thanks,

Multiple ASM instances on a single node are supported but not recommended due to several issues you could encounter during that kind of configuration.
Possible interraction between those instances for identification of each disk area usage,each disk area permissions , database instance to asm instance mapping and so on, could result in unwanted behaviour, as ASM is in some way just oracle's representation of LVM.
Intention is that any kind of distinction/separation of oracle related data under the ASM should be done through the disk groups.
So it seems it would be better to apply this kind of logic rather than doing suspiciously magical and rare configurations that could bring you similiary strange and unexpected problems.

Converting from Sinlge-Node Oracle Apps Instance to 2 Node Instance

Hi,
I am in the process converting my Single Instance Oracle Apps 11.5.10.2 instance on Windows 2003 server to a 2 Node instance. I want to move the DB Tier only to another Windows 2003 server.
Plz suggest how I can achieve this. Can I use 'adcfgclone appsTier' to get this done.
Rgds,
Thiru

1) Run "perl adpreclone.pl dbTier" on the source database node
2) Run "perl adpreclone.pl appsTier" on the source application node
3) Shutdown the application/database services and copy the(<sid>db, and <sid>data) directories to the target node
4) Run "perl adcfgclone.pl dbTier" on the target database node
5) Make sure the database and the database listener are up and running
6) Run "perl adcfgclone.pl appsTier" on the source application node
7) Start the application services

Moving RAC/ASM to single-node non-rac SET NEWNAME not working

Good morning,
I'm trying to restore a rac/asm database to a non-rac environment to simulate disaster recovery under worst-case circumstances.
Here is as faras I have been able to get

I noticed that it's trying to create the datafile. Shouldn't it be giving me a "Restoring datafiles from backup piece" clause? Also it appears to be trying to recreate the datafiles in their old location. Any thoughts on how to get around this.
Using the db_file_name_convert does allow me to restore files to the filesystem, but they use names such as "omf_*" and I'm not sure if it's converting the files properly from ASM format.
Thanks!

Hi,
I assume your problem is either in your pfile ( but you indicate you have removed all RAC settings), or in your control file.
I would recommend to remove the control files and create them later as soon as the datafiles have been restored, using the commands:
STARTUP NOMOUNT
CREATE CONTROLFILE REUSE DATABASE "OMST01" NORESETLOGS FORCE LOGGING NOARCHIVELOG
-- SET STANDBY TO MAXIMIZE PERFORMANCE
MAXLOGFILES 100
MAXLOGMEMBERS 2
MAXDATAFILES 1024
MAXINSTANCES 8
MAXLOGHISTORY 10210
LOGFILE
< your logfiles >
DATAFILE
< your datafiles >
CHARACTER SET <your character set>;So the steps are
Startup nomount with the pfile
Restore the datafiles using rman
Shutdown the database
Use above script to create the control files
It is possible you need to use the RESETLOGS option instead of the NORESETLOGS

Load balancing on rac database with single node appsTier

Hi,
Please advice me, I am working on to configure load balancing on appstier, following is my setup and steps I did so far.
Host name      Services
Clelx062ptlge --     Rac 1 – only database
Clelx063ptlge --     Rac 2 – only database
Clelx042ptlge --     All apps services including concurrent managers
I have two R12 database(UDEV -- development & HRQA -- UAT), I only made changes in apps tier xml file of udev for some load balancing parameters, following are the changes I did.
*<TWO_TASK oa_var="s_tools_twotask" osd="unix"> udev_806_BALANCE </TWO_TASK>*
*<CP_TWOTASK oa_var="s_cp_twotask" customized="yes">udev_806_BALANCE</CP_TWOTASK>*
*<TWO_TASK oa_var="s_weboh_twotask" osd="unix"> udev_BALANCE </TWO_TASK>*
I changed the values from "UDEV" to given above value. After the above change I ran autoconfig. Then Concurrent managers and forms services are not automatically getting failover to second database node, I need to bounce services to fail it back to other available Rac node. Please note that we have only one appsTier
Thanks,
Tanveer Mohammed.

Hi,
Yes, i have checked the doc referenced, and already did the steps given in the doc. Also i did all the steps given into ID 388577.1 but still Concurrent managers and forms services are not automatically getting failover to second database node, I need to bounce services to fail it back to other available Rac node.
Please advice...

Can we change the UCCX server from single node to the first node without affecting it's configurations

Hi all,
Firstly I was using the single CUCM7.0 server with the single UCCX 7.0 server. Now I am going to add the second CUCM and UCCX in the cluster. I was first configured the UCCX server as a single node. Now I have to configure this as a first node. How I could configure this from single node to the first node without affecting it's configurations..??????
Regards
Ali Raza

Hi Aaron,
How could we do the change on Imhost file. How we add the both servers in that file?
Below is the Imhost file txt.
# Copyright (c) 1993-1999 Microsoft Corp.
# This is a sample LMHOSTS file used by the Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to computernames
# (NetBIOS) names. Each entry should be kept on an individual line.
# The IP address should be placed in the first column followed by the
# corresponding computername. The address and the computername
# should be separated by at least one space or tab. The "#" character
# is generally used to denote the start of a comment (see the exceptions
# below).
# This file is compatible with Microsoft LAN Manager 2.x TCP/IP lmhosts
# files and offers the following extensions:
#      #PRE
#      #DOM:
#      #INCLUDE
#      #BEGIN_ALTERNATE
#      #END_ALTERNATE
#      \0xnn (non-printing character support)
# Following any entry in the file with the characters "#PRE" will cause
# the entry to be preloaded into the name cache. By default, entries are
# not preloaded, but are parsed only after dynamic name resolution fails.
# Following an entry with the "#DOM:" tag will associate the
# entry with the domain specified by . This affects how the

# centralized lmhosts file to be maintained on a server.
# It is ALWAYS necessary to provide a mapping for the IP address of the
# server prior to the #INCLUDE. This mapping must use the #PRE directive.
# In addtion the share "public" in the example below must be in the
# LanManServer list of "NullSessionShares" in order for client machines to
# be able to read the lmhosts file successfully. This key is under
# \machine\system\currentcontrolset\services\lanmanserver\parameters\nullsessionshares
# in the registry. Simply add "public" to the list found there.
# The #BEGIN_ and #END_ALTERNATE keywords allow multiple #INCLUDE
# statements to be grouped together. Any single successful include
# will cause the group to succeed.
# Finally, non-printing characters can be embedded in mappings by
# first surrounding the NetBIOS name in quotations, then using the
# \0xnn notation to specify a hex value for a non-printing character.
# The following example illustrates all of these extensions:
# 102.54.94.97     rhino         #PRE #DOM:networking #net group's DC
# 102.54.94.102    "appname \0x14"                    #special app server
# 102.54.94.123    popular            #PRE             #source server
# 102.54.94.117    localsrv           #PRE             #needed for the include
# #BEGIN_ALTERNATE
# #INCLUDE \\localsrv\public\lmhosts
# #INCLUDE \\rhino\public\lmhosts
# #END_ALTERNATE
# In the above example, the "appname" server contains a special

How to clone a 11.1.0.7 oracle single node db with asm instance

We need to clone a 11.1.0.7 environment with single node db plus asm storage used.
I googled everywhere , and a lot notes on ASM with RAC cluster clone provided but no document for ASM with single node.
Please help.
Thanks

How to clone a 2-node ASM RAC db to a 3-node ASM RAC db by RMAN?

We need to clone a 2-node ASM RAC db to a 3-node ASM RAC db by RMAN. I would think this will be about the same as a regular single db procedure by RMAN mostly. However, in 3 node RAC, there will be additional instance thread in redo (thread 1,2, and 3). Questions will be
1. Should I use CRSCTL to add new instance (3rd)? -- I guess yes
2. Should I create additional online redo group for thread 3? -- I guess yes
3. Should I create addition undo tablespace? -- I guess yes
Can any body provide a procedure of cloning the DB?
Thanks!

Not just easy as next, next, next
version depenedencies and etc.

How does a RAC DB 'spread' from single instance to multiple instances ?

GI/RDBMS Version: 11.2.0.3
OS: Oracle Linux 6.3
Filesystem : ASM
When a RAC database is created using dbca , Manually , or RMAN restore, the DB is created in the Node1 first with cluster_Database=FALSE .
Then you run the following commands (for 3-node RAC) from Node1
srvctl add database -d lmnprod -o $ORACLE_HOME -p +LMNPROD_DATA01/lmnprod/spfilelmnprod.ora
srvctl add instance -d lmnprod -i lmnprod1 -n hwcarser290
srvctl add instance -d lmnprod -i lmnprod2 -n hwcarser291
srvctl add instance -d lmnprod -i lmnprod3 -n hwcarser292
Once the DB is created,mounted and opened in Node1 and the above commands are executed , you set cluster_Database=TRUE and startup the Instance2 and Instance 3 in Node2 and Node3.
I just want to know how does Node2 and Node3 becomes aware of the DB and joins the DB cluster ? What happens internally ?

Generally speaking, registering in OCR is not required for database to be a cluster database.
Migration from single-instance database to cluster consists of creating redo logs and undo tablespace for new instance and enabling this instance (thread). If database is policy-managed, this is done automatically for new node.
