TAF Service in RAC 10g
Hi Experts,
i need your guidance. actually we have oracle 10g (10.2.0.4) RAC running with three nodes on AIX6.1 64bit. and TAF service is not configured. problem is this, when one of three node get down due to any reason, say for maintainence. then client are still trying to connect with down node. and when they try to connect with down node then they face delay in connection. below is the service that is being used in client side.
orcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1_vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = node2_vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = node3_vip)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 180)
(DELAY = 5)
1- question is why client go to down node and face delay in connection.
2- we should configure TAF service to overcome this ? what is the function of TAF service if any recommended MOS or other doc is available please share it

On Metalink/MOS there's doc [ID 334471.1] amongst others, but just do a search on 'TAF' yourself and you'll find many articles.

DBYou can say Configuration instead of creation of TAF in RAC.
Then only session can failover to other nodes when active node goes down/evicted.
Is it mandatory or not depends on your requirement. :) That is the main concept of introducing TAF in RAC. still if you wont use then what is the need to have RAC in your environment.? -

Edited by: user13405005 on Aug 29, 2011 11:40 PMHi,
don't worry about GSD. GSD is only used if you also run 9i databases in the cluster. Even though it should state as OFFLINE (not as unknown), I would not care about that.
However ONS should not be in the status UNKNOWN.
Can you do the following:
srvctl start nodeapps -n
To restart the ONS and see if it stays.
Also post the output on onsctl debug
(All from CRS Home).

Failed to start TAF service on standby db
Hi, we have a DG configuration based Oracle RAC 10g R2 (2 nodes). After switchover to standby db and start the TAF service, I got the following errors:
PRKP-1030 : Failed to start the service appTAF.
CRS-1007: Failed after successful dependency consideration
CRS-0223: Resource 'ora.standby.appTAF.cs' has placement error.
So basically TAF service won't start. Does anyone see this error before?
Thanks in advance.The interesting part is that there is no error in the alert log.

Edited by: user12924280 on Apr 6, 2013 12:36 AMSince you didn't say "thank you", I assumed my time was of no value to you.
However, I shall try again.
There is no relationship between instance failure and VIP failover. How can there be? What if you are running ten instances on each node, and one fails? Would you want the VIP to relocate? And I've already told you how to test it: kill the node. Just reboot it. -
Problem of using OCFS2 as shared storage to install RAC 10g on VMware
Hi, all
I am installing a RAC 10g cluster with two linux nodes on VMware. I created a shared 5G disk for the two nodes as shared storage partition. By using OCFS2 tools, i formatted this shared storage partition and successfully auto mounted it on both nodes.
Before installing, i use the command "runcluvfy.sh stage -pre crsinst -n node1,node2" to determine the installation prerequisites. Everything is ok except an error "Could not find a suitable set of interfaces for VIPs.". By searching the web, i found this error could be safely ignored.
The OCFS2 works well on both nodes, i formatted the shared partition as ocfs2 file system and configure o2bc to auto start ocfs service. I mounted the shared disk on both nodes at /ocfs directory. By adding an entry into both nodes' /etc/fstab, this partition can be auto mounted at system boots. I could access files in shared partition on both nodes.
My problem is that, when installing clusterware, at the stage "Specify Oracle Cluster Registry", I enter "/ocfs/OCRFILE" for Specify OCR Location and "/ocfs/OCRFILE_Mirror" for Specify OCR Mirror Location. But got an error as following:
----- Error Message ----
The location /ocfs/OCRFILE, entered for the Oracle Cluster Registry(OCR) is not shared across all the nodes in the cluster. Specify a shared raw partition or cluster file system that is visible by the same name on all nodes of the cluster.
------ Error Message ---
I don't know why the OUI can't recognize /ocfs as shared partition. On both nodes, using command "mounted.ocfs2 -f", i can get the result:
Device FS Nodes
/dev/sdb1 ocfs2 node1, node2
What's the possible wrong? Any help is appreciated!
Addition information:
1) uname -r
2.6.9-42.0.0.0.1.EL
2) Permission of shared partition
$ls -ld /ocfs/
drwxrwxr-x 6 oracle dba 4096 Aug 3 18:22 /ocfs/Hello
I am not sure how far this following solution is relevant to your problem (regardless when it was originally posted - may help someone who is reading this thread), here is what I faced and here is how I fixed it:
I was setting up RAC using VMWare. I prepared rac1 [installed OS, configured disks, users, etc] and the made a copy of it as rac2. So far so good. When, as per the guide I was following for RAC configuration, I started OCFS2 configuration, faced the following error on RAC2 when I tried to mount the /dev/adb1:
===================================================
[Root @ *rac2* ~] # mount - t ocfs2 - o datavolume, nointr / dev / sdb1 / ocfs
ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid
mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted" mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted"
===================================================
After a lot of "googling around", I finally bumped into a page, the kind person who posted the solution said [in my words below and more detailed ]:
o shutdown both rac1 and rac2
o in VMWare, "edit virtual machine settings" for rac1
o remove the disk [make sure you drop the correct one]
o recreate it and select *"allocate all disk space now"* [with same name and in the same directory where it was before]
o start rac1 and login as *"root"* and *"fdisk /dev/sdb"* [or whichever is/was your disk where you r installing ocfs2]
Once done, repeat the steps for configuring OCFS2. I was successfully able to mount the disk on both machines.
All this problem was apparently caused by not choosing "allocate all disk space now" option while creating the disk to be used for OCFS2.
If you still have any questions or problem, email me at [email protected] and I'll try to get back to you at my earliest.
Good luck!

Will Nodeapps register the listener service of RAC database?
Hi Friends,
In 10g RAC will Nodeapps register the listener service of RAC database?

Regards,
DBHi,
This is expected behavior. The default listener (listener_nodename) could be starte and stopped with nodeapps.
srvctl listener is mainly for specific listeners that are other than default.
http://docs.oracle.com/cd/B19306_01/rac.102/b14197/whatsnew.htm#sthref6
If you create additional Listeners with non-default names, in other words, with names other than the name listener_nodename where nodename is the name of the node on which the Listener resides, then you must start and stop these Listeners with SRVCTL commands.

PRKP-1030 CRS-1007 CRS-0223 while starting TAF Service !
Hello Gurus,
I have CRS 10.1.0.4 with RAC DB 10.1.0.4 on top of Sun cluster 3.1 / Solaris 9 box - 2 nodes.
All nodesapps, DB and instances are online and fine when quering CRS_STAT.
I have added TAF service using DBCA, it gave me an error when it is created.
The same error i get when i try to manulally start it up :
==========================================
$ srvctl start service -d TEST -s TAF_TEST
PRKP-1030 : Failed to start the service TAF_TEST.
CRS-1007: Failed after successful dependency consideration
CRS-0223: Resource ora.TEST.TAF_TEST.cs has placement error.
==========================================
Any ideas ?
Please advise.
Cheers,
FerasTry deleting the services ,the database resource and its instances ,then add the database again but,
add the database instance node name with lower case ,if it was in upper case.

TAF Service OFFLINE on standby node
Hi,
We have created primary and secondary RAC. A TAF service which is ONLINE on primary is added to standby side and is enabled but it shows the OFFLINE status. Is this default behaviour. We can't start is using "srvctl start service" command. My understanding is since the DB is physical standby which is not open, this is the reason the service is OFF line. Once the standby switches to primary it can be brought up. Correct?You should still be able to bring up the standby as read only. During managed recovery the database is in a mounted state and therefore can't be connected to via the listener.

Thank youI had this problem and resolved it by transporting the file to the installation server with the correct ftp datatype (binary).
On page 54 of the install guide (..Server\Oracle_Business_Intelligence\doc\doc\bi.1013\b31765.pdf) that comes with the installation files, there is an instruction to make sure that any ftp activity is done in binary.
This may not have occured with the license.xml file if you use a tool which offers the "feature" of automatic datatype recognition.
Hope this helps. -
