Datafile is not accesable from One NODE

Hi All,
We have two node cluster RAC we are able to access the datafile from one node from another node getting error like..
ERROR:
ORA-01157: cannot identify/lock data file 6 - see DBWR trace file
ORA-01110: data file 6: '/dev/md/racgcp/rdsk/d548'
If we offline the TS the error is not appearing...!
And we tried to drop but its hanging..
Please Suggest
Thanks.

ERROR:
ORA-01157: cannot identify/lock data file 6 - see DBWR trace file
ORA-01110: data file 6: '/dev/md/racgcp/rdsk/d548'Hi,
is this visible in the first node ?
What is the output of
select name from v$datafile where name like '%dev/md/racgcp/rdsk/d548%';Might you have given wrong file name, give the file_id instead of name. Post if any errors.
Celero,
It is tipical when you have created a tablespace using local node storage instead of the shared storage used by the RAC. Then, it will be only visible from the node it was created.In RAC database datafiles in shared loacation, if you configure tablespace using local node how can you say it as RAC... can you please describe your views more.
Thanks

How to failover SCAN VIP and SCAN Listener from one node to another?

Environment:
O.S : HP-UX B.11.31 U ia64
RDBMS: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
It is a 2 Node RAC.
Question:
How to failover the SCAN VIP and SCAN LISTENER running on node 1 to node 2?
What is the relation between standard LISTENER and SCAN LISTENER ?
Why do we need LISTENER, when we have SCAN LISTENER ?
When I tried with SRCVTL STOP LISTENER , I thought the SCAN LISTENER adn SCAN IP will failover, but it did not?
Also please clarify if I use SRVCTL RELOCATE SCAN -i 1 -n Node1
Actalluy I am trying that by moving the SCAN listeners so that when I do PSU 7 patching on 1 node, no incoming attempt to connect will spawn
a process and thereby opening files in $ORACLE_HOME (which would prevent the patch from occurring)
Please clarify my queries.
Thanks, Sivaprasad.S

Hi Sivaprasad,
1. The following link will help you for SCAN VIP and SCAN LISTENER failover from 1 node to another.
http://heliosguneserol.wordpress.com/2012/10/19/how-to-relocate-scan_listener-from-one-node-to-another-node-on-rac-system/
http://oracledbabay.blogspot.co.uk/2013/05/steps-to-change-scan-ip-address-in.html
2. The Standard LISTENER is specific for particular node for which it is running. It cannot be relocated as its specific for the node its running. SCAN listeners are not replacements for the node listeners.A new set of cluster processes called scan listeners will run on three nodes in a cluster (or all nodes if there are less than 3). If you have more than three nodes, regardless of the number of nodes you have, there will be at most three scan listeners. So no relation for standard LISTENER and SCAN LISTENER.
3. Hmmm. let me put it in easy way for this question. All the RAC services like, asm, db , services, nodeapps registers with this SCAN_LISTENER. So if any of these services (asm, db , services, nodeapps) got down/not running, the SCAN_LISTENER will know the down status, and if any client requests to access the node/service which is down, the SCAN_LISTENER will redirect the client request to the least loaded node. So here all these process will happen without the knowledge of client. And As usual the standard LISTENER looks only for incoming request to connect with the database. So we need both LISTENER and SCAN LISTENER.
4. If you provide SRCVTL STOP LISTENER, it stops the default listener on the specified node_name, or the listeners represented in a given list of listener names, that are registered with Oracle Clusterware on the given node. No failover will happen under this case.
5. Yes you can relocate if you want to relocate the scan.
Hope this helps!!

Move OMS repository from one node to another&configure agents.OEM10.2.0.4

Hi experts,
I explain:
my environment has two nodes:
nodeA and nodeB (OSLINUX 64BITS)
nodeA+nodeB has a database, DB1, that is a OracleRAC between these two nodes.
OMS is installed on this database.
I want to move repository,OMS in a third node, separately from these two, and migrate database repository to this third node.
II have checked note. 382698.1
How to move OMS repository from one node to another - Step-by-Step guide.
but my version is 10.2.0.4 (not 9i) and in this note don explain how modify file AGENT_HOME>/sysman/config/emd.properties.
Can you help me, please?
Thank you for your time.
JRC

Once you move the repository, go to each agent and do this:
1) Stop agent and cleanup the status, etc...
cd <AGENT_HOME>
bin/emctl stop agent
rm -r ./sysman/emd/state/*
rm -r ./sysman/emd/upload/*
rm -r ./sysman/emd/collection/*
rm ./sysman/emd/lastupld.xml
rm ./sysman/emd/agntstmp.txt
rm ./sysman/emd/blackouts.xml
rm ./sysman/emd/protocol.ini2) Then edit the $AH/sysman/confiig/emd.properties with your new data (host:port):
REPOSITORY_URL=https://newhost.domain.com:1159/em/upload
emdWalletSrcUrl=http://newhost.domain.com:4889/em/wallets/emd3) And finally start the agent:
$AH/bin/emctl start agent
$AH/bin/emctl upload:p
PS: And be patient, it may take up to 30 minutes to re-sync with the new OMS.

EM DB console works only from one node?

In my 2 node RAC the enterprise manager database console works only from one node i.e the url shows login page only from one node.
http://NODE2:5500/em------>WORKS, SHOWS LOGIN PAGE AND CAN MANAGE ALL INSTANCES FROM HERE
http://NODE1:5500/em------>DOES NOT WORK, DOES NOT SHOW THE LOGIN PAGE.
Please clarify.
Kadhim

I have to guess ... (because you tell neither OS nor database version). Assuming it's 10gR2 or higher, that's expected behaviour, dbconsole runs on one node only, the so-called master node. You can change that, see the documentation or this metalink note:

How to drag and drop user from one node to other node.

Dear All,
How to drag and drop user from one node to other node.I tried but no success.
What are precautions to be taken.
Cay anybody kindly explain it.
Thank you.

Hello, if you had this message you had created BP....
Now you don't have to user USERS_GEN this transaction is used only in first action, when you create the user in R/3 and then you pass this user to EBP in the organizational structure.
Now you have to:
1) Go to PPOMA_BBP
2) Double click on organizational unit that you want to put this user (purchasing organization or purchasing group box for example)
3) Select assign button in the top of the functions in the transaction
4) Click on incorporates -- position
5) Put userID that you want to add in this organizational unit
6) Click Save

I am really pisssed off at two characteristics of Firefox 4: Size and position do not stick, and view menu selections do not stick from one use to the next.

I am really pissed off at two characteristics of Firefox 4: 1) Toolbar selections don't stick and 2) firefox window position and size settings do not stick from one use to the next.
The Bookmarks toolbar is the selection that does not stick, and Firefox, even though I set it to the size and position I want every time I use the program, always loads flush left, full top to botton, and about 1/3 of the width of the screen EVERY TIME it loads. These two characteristics are extreme pains in the ass.

RAC-DATA FILE ACCESSING ISSUE FROM ONE NODE

From yesterday onwards, from one instance accessing data from a specific data file showing the below error, whereas accessing from other node to the same datafile is working properly.That would be due to some kind of failure in the shared storage layer.
RAC needs the very same storage layer to be visible and available on each RAC node - thus this needs to be some form of shared cluster storage.
Should a piece of it fails on one node, that node would not be able to access the RAC database files on that shared storage layer - and will throw the type of errors you are seeing.
So how does this shared storage layer look like? Fibre channels (HBAs) connected to a Fibre Channel Switch and SAN - making SAN LUNs available as shared storage devices?
Typically a shared storage failure would throw errors in the kernel log. This is because the error is not an Oracle error, but a kernel error. As it is in your case. The bottom error on the error stack points to the root cause:
ORA-01157: cannot identify/lock data file 75 - see DBWR trace file
ORA-01110: data file 75: '/dev/vg_rac/rraw_tap3plus_temp_live05'
ORA-27041: unable to open file
HPUX-ia64 Error: 19: No such device
So HP-UX on that node is not seeing a specific shared storage device.

Cluster VMs not accessible from other node hyper-v 2012 r2

I have implementing 3 node cluster using Windows server 2012 r2 hyper-v environment, Scenario as below....
3 HP server, every server 4 NIC`s, i made team using 4 NIC`s, and Cisco switch port configured as ether-channel and trunk port.
cluster up and running across all node, suddenly i have faced that i can`t access VM when its not on the same node from where i am accessing Cluster manager. but i can access that VM only if i log on that owned node via cluster manager.\
Please help.
Thanks
Shipon

Hi Shipon,
Your network configuration not meet the cluster network requirement,
Network adapters and cable (for network communication): The network hardware, like other components in the failover cluster solution, must be marked as "Certified for Windows
Server 2008 R2." If you use iSCSI, your network adapters should be dedicated to either network communication or iSCSI, not both.
In the network infrastructure that connects your cluster nodes, avoid having single points of failure. There are multiple ways of accomplishing this. You
can connect your cluster nodes by multiple, distinct networks. Alternatively, you can connect your cluster nodes with one network that is constructed with teamed network adapters, redundant switches, redundant routers, or similar hardware that removes single
points of failure.

Can I move sessions from one node to another in Oracle RAC 11g?

Hi everybody,
When I need to shutdown one node for maintenance, can I move the sessions connected to that node to the other one? I know TFA but I'm not using it right now, I just wanted to know if I may move the sessions without warning everyone that some of them will be disconnected.
Thanks for your help.

sol.beach, thanks for your answers, just a few words:
When you answered "NO, shutting down a node will disrupt every session on that node". it was confusing, as I wasn't asking for the behavior of the sessions when the node is shut down, you should've answered "NO, there's no way to manually relocate a session", that would have been clear since the beginning, also asking me to post a SQL didn't help much either, I honestly thought I didn't explain well my doubt.
Thanks anyway.
The answer is a no but the question for you, why you want to do that anyways?

Data not transfering from one form to another

I have designed two forms in which i want to transfer data from one form to another which contains lot of fields.Process starts wid filling the first form(form1) from the workspace and all the data from dat form will be transfered to next level user who is having form2.Both forms contains two pages each.I tried with the SETVALUE ACTIVITY after designing two forms but its showing error.

No am not using any xml schema .i have designed the two forms with the same fileds and field names.what cpould be the problem.After submitting the task from the start process it is going to the next user level but the form is getting added twice in the to do list of that user and data is not getting bound.If u want i can sned u my lca files or forms.

Failover did not happen when one node went down!!! PLEASE HELP

Hi gurus,
Yesterday one disaster struck my RAC database. We have two node cluster and it is 10.2.0.2, both of them located in different sites, yesterday suddenly power went down and the one of the network switch went down and got destructed, node one of RAC database was connected to that switch, but the failover did not happen to the node two as this should be the case when one node goes down the other should be available for all the node one sessions/connections.
when I tried to ping/telnet the node 1, it was not happening because the switch was down, the network guyz connected the cables to other switch available. When I connected to the node 1, it was showing "Oracle is not available" message.
And when I tried the other node, it was the same case but I did not see any error in alert log file. Then my TL restarted both the nodes and then the database was available.
I am very confused that how the failover did not happen and how the database went down, PLEASE suggest something to how to identifiy what was happened. Thanks & Regards

Thanks for your reply,
after the network switch was replaced we connected to both the nodes and found that the instances are down with no reason given in the Alertlog file. We just restarted both the instances and then the database was up and the clients connected to both the instances with equal sessions on both the instances. I want to know that whether the failover can be done at the application side or it should be done on the database side i,e; in tnsnames.ora file with the required parameters? as in our scenario there is no failover configuration in the tnsnames.ora file.
Thanks & Regards

Reports not posting from one server

We're on PT 8.48.10, HRMS 8.8. We have two web servers which are load balanced with a Cisco load balancer (don't have specifics on the load balancer model, but I can request it if need be. I know sticky sessions and source address NATing are enabled). We have two app servers and one process scheduler, all on AIX 5.3. ServerA has a web server, app server and process scheduler on it. ServerB has a web server and app server. The report repository is set up to use ServerA's web server. The report repository is on an NFS mount shared between the two servers. Both servers have read/write permissions to the share.
We recently went to SSL terminating at the load balancer. We are using HTTP distribution, making the URL the VIP address (https://vip.intranet:8380/psreports/hrms), the URI is using http with the URI Host set to ServerA.intranet and URI port 8380 (the SSL port to the load balancer and the actual web server port are the same). The URI resource is SchedulerTransfer/hrms.
The issue we're experiencing is that if the load balancer puts the user on ServerA, then there is no issue with reports posting. If they get put on ServerB, the reports go to Not Posted status. The message logs shows the following:
+2:02:37PM PSUNX failed to post files to the report repository. Server scheduled to try again on 2012-02-06-12.02.51.000919. See log+
+10 2:02:52PM Report Repository URL is: http ://ServerA.intranet:8380/Scheduler Transfer/hrms (63,68)+
+10 2:02:52PM Error getting report repositor y location. (63,85)+
+10 2:02:52PM SchedulerTransfer Servlet error.+
+10 2:02:52PM Successful Http Reply Code: 20 0 - OK (63,57)+
+2:02:52PM HTTP transfer error.+
The space in "SchedulerTransfer" is not in the report node setup. The DSTAGNT log didn't give much more detail:
PSDSTSRV.1167494 (9) [02/06/12 12:02:37 PostReport](3) HTTP transfer error.
I was thinking that maybe there is something wrong or missing in the /etc/hosts file, but I'm not sure what. Also, I swtiched the report node to be on ServerB, and then ServerA could not post reports. Any ideas or suggestions?

Hi,
A few possible things you might want to check:
1.
Portal URI in the portal tab of the default local node, is this pointing to the correct webserver url and port
2. Check firewall rules (ports) between processcheduler and webservers
3.
Is psreports on both webservers a valid directory as mentioned in configuration.properties and validate write access on psreports folder
4.
URI host and port on Proces Sheduler Report node, is is this pointing to the correct webserver url and port

After Settlement, Cost not transfer from one WBS to another WBS in customer project

Hello Experts,
I am trying to settle cost from one WBS (i.e. XYZ-000014-1) to another WBS (i.e. XYZ-00001)in customer project.
Its a revenue type of project.
I have added 4 internal activities in an network under one WBS (i.e. XYZ-000014-1).
Got actual values after confirming activities, then settle that network cost on WBS (i.e. XYZ-000014-1) through CJ88.
Now while trying to settle that cost from WBS (i.e. XYZ-000014-1) to WBS (i.e. XYZ-00001) through CJ88, system not showing any result.
Kindly give ur valuable inputs.
Regards,

Kindly tell me that is it a standard functionality of SAP that through CJ88 we can transfer cost from WBS to WBS.
Technically ,Yes.Cost is actually transferred from one cost object to another cost object.
I hv discuss the same with some of my frds ...some are denying the same that its not a standard functionality of SAP to transfer cost on same cost object.
Instead of 'transfer' I would rather use the word 'settlement' . Practically, they are right as projects-WBS are temporary endeavors of companies, and cost can not reside on WBS permanently as it has to settle to some entity (organizational unit) which can be accounted during the reconciliation of their chart of accounts and balance sheets.
SAP has provided us an option to settle our cost to WBS and hence its standard . Generally, we use it when we have 1 WBS at level 1 and all lower WBS's costs is settled to this WBS . Here, we specify Level 1 WBS as the receiver of cost of these lower WBS.
Hope,I am clear here.
Regards
Saurabh

I can not go from one app to another on my iPad without a hard reboot

I have just bought an iPad mini and my husband has a regular iPad. Neither one of us can move from one website or application to another without rebooting. I have no problem with my pc laptop. We are next to the router and the security is WPA-2 with AES.

Hi Marciaztx,
Perform a Reset on the iPad (different from just restarting).
Hold down on both the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears. When you see the Apple logo on the black screen, let go of the buttons. This “reset” fixes a lot of iPad issues and might work for your app switching issue.
Hope this helps!
