RAC node and disk ping

Hi,
I have a 10.2.0.3 RAC running on RHELv4. What is a node and disk ping in terms of Oracle RAC? I assume the node ping refers to the hangcheck-timer, or is this wrong? The only disk ping that I recall was in 9i but not heard of this in 10g unless it's something else.
Also, where would I configure these parameters?
Thanks.

Try ML Note 294430.1: "CSS Timeout Computation in RAC 10g (10g Release 1 and 10g Release 2)" for example.
Thanks.

Does Maintenance Wizard allow to register RAC node and if yes, then how?

Maintenance Wizard is not allowing to register additional nodes for RAC. This cause manual run for other nodes. Is there any way we can setup multiple nodes?
Example, we have two CM/Admin nodes and RAC database. We are using Maintenance Wizard version 2.19.
Thanks

Edit the following script to sort out bug 11699526.
$EOF_HOME/scripts/COMMON/eof1122e.sh
Line 131 reads "(CONNECT_DATA=(SID=${DB_SID})" change it to read "(CONNECT_DATA=(SERVICE_NAME=${DB_SID})".
Enter the database service name when configuring the DB nodes.
You will still need to do the OS related operations manually on node 2.

Oracle RAC Diskgroups and disks

Hi all,
I want to find out what disks are assigned to the diskgroups in my RAC.
I want to do that without using ASMCA, but rather using CLI.
I do know what diskgroups I have and on what nodes they're active using "crsstl status resource -l".
Is there a similar command to extract a mapping of disks to diskgroups?
Regards,
Igor.

Invalid B-tree node and disk stuck

Last night my 2 year old iMac froze up. When I re-started I received the flashing question-mark folder. I ended up inserting my OS X install disk and attempting to run the Disk Utility. I tried to repair the disk, but got the "Invalid B-tree node size" error with "The volume needs to be repaired."
I have tried a lot of things and will probably end up buying Disk Warrior and hoping that fixes it. BUT, I have another problem. I can't eject the OS X install disk. The option to eject is greyed out on the Disk Utility, the eject key doesn't work, and I can't find any way to unload the disk. Help would be appreciated.

If you have an external hard drive it would be easier to clone your system to the external then boot to the external and run Disk Warrior from there. However if your system won't boot in the first place that won't work. You could pick up a copy of Disk Warrior from the Apple store.

Query on setting of ORACLE_HOME in RAC node and more errors

i m following oracle docs for install Oracle 10g R2 RAC on RHEL 5.
i am able to get through most of the part but one minor thing is still bugging me.
Enter commands similar to the following to set the ORACLE_BASE and
ORACLE_HOME environment variable in preparation for the Oracle Clusterware
installation:
■ Bourne, Bash, or Korn shell:
$ ORACLE_BASE=/u01/app/oracle
$ ORACLE_HOME=/u01/crs/oracle/product/10/app
$ export ORACLE_BASE
$ export ORACLE_HOMEthe above extract from the docs (B14203-09) says ORACLE_HOME should be set to the dir where clusterware is installed.
my query is do we change this ORACLE_HOME to '/u01/app/oracle/product/10/db_1' when we install the oracle database after we finish installing the clusterware.
Further, permissions for the /u01/crs directory should be root:oinstall and 775 during the installation of the clusterware and changed to 644 after installation of clusterware. is that correct? is it 644 or 640? does it need read access for every one?

i initially thought not setting the oracle_home to the crs directory was the cause of the error message

Rac node failed how do you bring it back up?

Example: If there are 3 RAC nodes and one becomes unavailable/fails, how do you bring it back up?

There are typically two basic reasons why a RAC node will go down.
A cluster issue, causing the node to be evicted. This usually means the node lost access to the cluster storage (e.g. no access to voting disks), or lost access to the Interconnect.
An o/s issue causing the node to fail. E.g. a kernel panic due to a page swap and memory not syncing, or a soft CPU lockup, etc.
You need to determine why it went down, and determine what is needed to enable it to join the successfully cluster again.

2 x T2000 and RAC and disk formatting

Hi,
Do I have to format my disks differently on my T2000s simply because I am planning on using Oracle10G version 2 RAC for both boxes?

I am not sure what you are aiming at.
The oracle clusterware needs to have a cluster filesystem for its voting and registry files, because these files needs to be shared by all the nodes you are going to use RAC on. (which means the filesystem needs to be able to cope with concurrent access from more than one node)
Next, the oracle database files (datafiles, tempfiles, online redologs, spfile) need to be shared too, which can be either by a cluster filesystem, using raw disks or using ASM. The same is the matter here, these files need to be able to cope with multi-node access.
So, it actually depends on how you have formatted your disks currently, but assuming you mean solaris, and disks formatted with ufs, yes, some disks needs to be reformatted.

2 node RAC: one 10gR2 node and one 11.2.0.3 node on Solaris 10.

Is it possible to have a mixed Oracle version 2 node RAC with 10gR2 database on one machine and 11.2.0.3 database installed on the other machine. Has anyone done this?

Hi,
if you are talking about setting up a RAC, and having a database 10g running on one node, and a different database 11g running on the other node this is possible.
You will have to use the newest clusterware/GI (11.2.0.3) and multiple Oracle Homes (One for 10g and one for the 11.2.0.3).
If however you want one database with 2 instances running different versions: Then No.

RAC node connected to outside DB and pass 2 IP address

Experts,
we have a 4 nodes 11.1 RAC at red hat
As we know each node have 3 IP. --public, vip and privated IP.
it works well in domain inside network.
But we get a problem when try to connect to outside network client's database.
the connection string pass 2 IPs to client firewall (based on network monitor).
listener log show that connection is OK. But Conection is still blocked by client's firewall side.
The client network staff told us that we passed two IP address during connected connection.
Could some experts explain why does the RAC node's connected requested passs two IP to client database?
It is only discovered by network staff. we could not see 2 IP information in listener log file.
Is it our firewall NAT setting issue? or client firewall NAT setting issue
Thanks
Jim
Edited by: user589812 on Jan 21, 2010 2:25 PM

Hi Experts
The Two IP addresses that were being passed were one of the load balancer and one of the db server. the load balancer was supposed to mask the load balancer IP address and only pass the db IP address. Somehow, we were sending both IP to client database--outside network. But IT works well in inter network side. How to eliminate the load balancer IP address from coming to client network firewall --to client database server side?
I looking for help!

Replication between 2 node RAC environment and standalone

I would like to find out if we can setup replication between a (2 node) RAC environment and standalone database located at different location. Any help regarding this would be greatly appreciated.

Thanks for the reply.
Consider for a moment I cannot implement dataguard/stream -- because I believe both involves licensing issue --- now only option left is writing my own code. If I right my own code what are the prerequisites for this and what do I have to keep in (technically)mind before i start implementing this. Any help or any lead would be greatly appreciated.

Log file sequential read and RFS ping/write - among Top 5 event

I have situation here to discuss. In a 3-node RAC setup which is Logical standby DB; one node is showing high CPU utilization around 40~50%. The CPU utilization was less than 20% 10 days back but from 9th oldest day it jumped and consistently shows the double figure. I ran AWR reports on all three nodes and found one node with high CPU utilization and shows below tops events-
EVENT WAITS TIME(S) AVG WAIT(MS) %TOTAL CALL TIME WAIT CLASS
CPU time 5,802 34.9
RFS ping 15 5,118 33,671 30.8 Other

Sql*Net more data from
client 24,171 1,087 45 6.5 Network
Db file sequential read 130,939 453 3 2.7 User I/O
Findings:-
On AWR report(file attached) for node= sipd207; we can see that "RFS PING" wait event takes 30% of the waits and "log file sequential read" wait event takes 30% of the waits that occurs in database.
Environment :- (Oracle- 10.2.0.4.0, O/S - AIX .3)
1)other node awr shows "log file sync" - is it due to oversized log buffer?
2)Network wait events can be reduced by tweaking SDU & TDU values based on MDU.
3) Why ARCH processes taking much to archives filled redo logs; is it issue with slow disk I/O?
Regards

We only apply on one node in a cluster so I would expect that the node running SQL Apply would have much higher usage and waits. Is this what you are asking?

RMAN, RAC, NFS, and server lock ups

Good day. My environment is:
--a 2-node RAC
--Enterprise Edition 11.2.0.3
--RHEL 5.1
The goal is to use RMAN to push backups to a shared NFS mount (on a different server). Both nodes will have access to this location (in the event one node goes down, the other can still run backups). Easy, right?
Wrong.
I've tried every NFS mount option in the book. Most work just fine, some don't. When I use the recommended NFS mount options:
rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp, vers=3,timeo=600, actimeo=0
or
rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp,noac,forcedirectio, vers=3,suid
The mount works normally. I can "ls" and "mkdir" and "touch" and "vi" and "cp" files back and forth from the NFS backup location to the RAC node all day long. No problems. However, when I try to do almost anything in RMAN which requires writing to the NFS backup location such as the command "backup archive all delete input;" (or even things as simple as a Crosscheck or RMAN configuration change which writes any changes back to the autobackup ControlFile) the node locks up. There are no errors (or if there are, I don't know where to find them), even when I use RMAN log.
Just to recap: I run a Crosscheck (or any RMAN process that writes to the NFS backup location), the node will lock up, and I can let it sit for a day, inaccessible, with CRSCTL on the other node saying it's offline, and the node will never come out of a "frozen" state. It cannot be pinged or connected to.
I think I can safely rule out NFS mount options at this point.
I understand (after extensive reading of MOS docs and testing) that RAC RMAN can and does suffer from inefficient I/O when writing to an NFS mount. I don't think that's the culprit either. The autobackup ControlFile is not that big and I cannot see how running a simple Crosscheck would lock an entire node.
I am hoping someone has encountered this in the past and hopefully it's just a simple misconfiguration somewhere.

My NFS line in /etc/fstab is (these options are for supporting 11.2.0.3, 11.1.0.7, and 10.2.0.4/5 simultaneously): server.domain:/NFS_Export /backup nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,actimeo=0,vers=3,timeo=600 0 0
Before you installed GI, did you by chance do a yum update? I've encountered a similar issue which ended up being due to mkinitrd creating a corrupted kernel; mkinitrd is invoked during the GI installation when the ADVM drivers are added and in my case mkinitrd created a new kernel prior to the new kernel being installed. Second to that, make sure you have the matching kernel headers to your kernel version. If they are different then you could probably get away with just creating a new kernel with mkinitrd and relinking GI/RDBMS homes, but be prepared to wipe GI and reinstall.

New boss wants to update system to the max to get best performance possible Money is a concern of course but budget is pretty high, Our use case is 12-16 users at same time, running reports some small others very large (return single row or 10000s or rows). reports take 5 sec to 5 minutes, Our job is get the fastest system possible, We have total of 8 licenses available so we can have 16 cores. We are also getting a 6tb all flash SSD array for database. we can get any CPU we want but we cant use parallel query server due to all kinds of issues we have experienced (too many slaves, RAC interconnect saturation etc, whack-a-mole). sparc has too many threads and without PS oracle runs query in single thread.
we have speced out the following system for each RAC node
HP ProLiant DL380p Gen8 8 SFF server
2 Intel Xeon E5-2637v2 3.5GHz/4-core cpus
768 gb ram
2 HP 300GB 6G SAS 15K drives for database software
this will give us total of 4 Xeon E5-2637v2 cpus 16 cores total (,5 factor for 8 licenses) and 1536 ram (leaving ~1400 for sga). this will guarantee an available core for each user. we intend to create very very large keep pool around 300 gb for each node that will hold all our dimension tables. this we hope will reduce reads from the SSD to just data from fact tables.,
Are we doing a massive overkill here? the budget for this was way less than what our boss expected. will that big an sga be wasted will say a 256gb be fine. or will oracle take advantage of it and be able to keep most blocks in there.
will an sga that big cause oracle problems due to overhead of handling that much ram?

Current System:
===========
a. Version : 11.2.0.3
b. Unix Sun
c. CPU - 8 cpus with 4 threads => 32 logical cpus or cores
d. database 4TB
e. SAN - 10k speed disk drives
f. 8gb SGA
g. 1.2 gb ??
h. Users --> 12-16 concurrent and run reports varying size
i. reports elasped time 5 sec to 5 mins
j. cpu license -->8
Target System
===========
a. Version: 11.2.0.3
b. HP ProLiant DL380p Gen8 8 SFF server
c. RAM --> 768 GB
d. 2 HP 300GB 6G SAS 15K drives for database software
e. large keep pool -->90 gb to hold all dimension tables.
f. SSD to just data from fact tables
g. SGA -->256gb
Reassessment of the performance issues of current system appears to be required.Good performance tuning expert is required to look into tuning issues of current application by analyzing awr performance metrics . If 8GB SGA is not enough,then reason behind so is that queries running in the system are not having good access path to select lesser data to avoid flushing out of recent buffers from different tables involved in the query. Until those issues are identified , wherever you go, performance issue wont be going away as table size increase in future , problem will reappear.Even if the queries are running with more FULL Scan , then re-platforming to Exadata might be right decision as Exadata has smart scan , cell offloading feature which works faster and might be right direction for best performance and best investment for future.Compression (compress for OLTP) could be one of the other feature to exploit to improve further efficiency while reading the lesser block in lesser read time.
Investment in infrastructure will solve a few issue in short term but long term issue will again arise.
Investment in identifying the performance issues of current system would be best investment in current scenario.

is your ASM instance up?
If not, trying bring up ASM instance up just by itself and see if it throws any error?

Private Interconnect: Should any nodes other than RAC nodes have one?

The contractors that set up our four-node production 10g RAC (and a standalone development server) also assigned private interconnect addresses to 2 Apache/ApEx servers and a standalone development database server.
There are service names in the tnsnames.ora on all servers in our infrastructure referencing these private interconnects- even the non-rac member servers. The nics on these servers are not bound for failover with the nics bound to the public/VIP addresses. These nics are isolated on their own switch.
Could this configuration be related to lost heartbeats or voting disk errors? We experience rac node expulsions and even arbitrary bounces (reboots!) of all the rac nodes.

I do not have access to the contractors. . . .can only look at what they have left behind and try to figure out their intention. . .
I am reading the Ault/Tumha book Oracle 10g Grid and Real Application Clusters and looking through our own settings and config files and learning srvctl and crsctl commands from their examples. Also googling and OTN searching through the library full of documentation. . .
I still have yet to figure out if the private interconnect spoken about so frequently in cluster configuration documents are the binding to the set of node.vip address specifications in the tnsnames.ora (bound the the first eth adaptor along with the public ip addresses for the nodes) or the binding on the second eth adaptor to the node.prv addresses not found in the local pfile, in the tnsnames.ora, or the listener.ora (but found at the operating system level in the ifconfig). If the node.prv addresses are not the private interconnect then can anyone tell me that they are for?
