RAC node Hung
Hi Friends,
Server info:
Windows 2003 server
Oracle 10.2.0.5, 2 Node RAC
We are having problem Hung Node 2 server due to Blue dump error. But in Oracle we are not getting any error on CRS & alertlogs. After restarted the server problem solved. How can we identify what could be the reason of server hang. We are not getting any error in Operating System side also. Is there any way to identify the problem of server hang after restarted server?
Thanks in advance.

Hi,
Thanks for your reply.
OS side also having no logs generated except "*Blue Screen Trap (BugCheck, STOP: 0x0000FFFF (0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000))*" . As per my knowledge this is not a Node eviction problem. We are not able to find any node eviction log in Oracle logs.
See this note:
*RAC on Windows: Oracle Clusterware Node Evictions a.k.a. Why do we get a Blue Screen (BSOD) Caused By Orafencedrv.sys? [ID 337784.1]*

What is best use of 1400 gb SGA (2 rac nodes 768gb each)
currently using 11.2.0.3.0 on unix sun sever with 2 RAC nodes each 8 UltraSPARC-T1 cpus (came out in 2005) four threads each so oracle sees 32 CPUS very slow(1.2 gb). Database is 4TB in size on regular SAN (10k speed).
8gb SGA.
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. -

RAC node outage causes SOA Suite 10.1.3.4 BPEL failure
Using weblogic 9.2 and the SOA Suite 10.1.3.4. We use a 10g Oracle RAC ( 2 nodes ); the WL cluster has a multi data source of 2 pools, each pool pointing to a single node in the rac, each pool deployed to the cluster, and the multi data source in load-balancing mode.
So the other night, one of the db nodes had a hardware failure ( ironically, with a remote monitoring / management card ). Annoying, but it should not have caused the BPEL servers to be in "FAILED NOT RESTARTABLE" status the next morning.

Both managed instances of the BPEL cluster failed, even though the 1st node of the Oracle RAC was still available.
Our 10.3 cluster, also using multi data sources to the same RAC for the OSB components, simply went on about its business using the remaining rac node pool.
Seems to be a single point of failure...We haven't changed the JDBC connection string yet, but we did run a test in the same environment while Oracle support considers the situation.
For the test, we simply shutdown one node of the RAC and watched to see what happens. Within the space of a minute, the JDBC "Failed Reserve Request Count" was increasing by thousands on every refresh of the screen. We restarted the RAC node after 5 minutes, by which time the "Failed Reserve Request Count" was over 190,000
The 2 BPEL managed servers remained in Running status and each created a 660 MB log file within that 5 minutes. In the original outage, the nodes were down for about 15 minutes. Most of the logging is being generated from within the oracle.tip.esb classes, not by the weblogic classes. It looks like that once the pool pointing to the downed RAC node becomes disabled, the Oracle BPEL code is still trying to use it even though the multi-source JNDI is the published lookup:

Exception while failing over to 2nd RAC Node
We are using Weblogic 10.3.4. Our setup is that we have a Web Application (A tapestry front end Web UI) and EJb 2.1 back-end talking to the Oracle database. The EJB’s are CMP. Our product always was just stand alone and it wasn’t until this release we needed to make it work with RAC. To get this to work we followed the model of having a Multidatasource with datasources pointing to our RAC nodes. We have two types of datasources that we use persistent and non-persistent. And we are using the Oracle thin driver – non-XA for RAC Service Instances, supporting global transactions.
When we do failover to the 2nd node we get a nasty exception in our GUI but after logging out and logging back it we are fine.
My question is that I assumed I shouldn't have to restart our web-application and it should have stayed up ?? Or is there something wrong with our setup ?
Thanks,
IanShowing us the exception and/or the error messages at the server might help...
Note that failing over does not save any ongoing connection or transaction that
had been to the dead RAC node... Does your web-app get-use-close JDBC
connections on a per-user-invoke basis, or does it hold onto connections?

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? -
Found the errors in CSSD logs of RAC node
Found the below error in CSSD logs in One of RAC nodes from 5:15 to 5:18 PM, after this the error got disappeared. Could anyone please have an idea what could be the reason of this error.
Also, at that time we didn't find any errors in the alert log.

Question on Rebooting RAC Nodes
Hi, I heard that when rebooting all RAC nodes, one has to wait at least 5 minutes between each node reboot. So you would reboot node 1 at 0 time, node 2 5 minutes later etc.
However, I could not find any documentation on this, can someone please point me to the right place to look? Thanks.I have not heard that before. I generally use srvctl to stop/start the databases, I do not think it waits 5 minutes between starting nodes as it does not take 15 minutes to stop/start the databases. As far as rebooting the hosts, the only time interval between machines was the time it took to send the reboot command to the host.

Multiple Standby Databases on same RAC nodes.
We have a 3 node Oracle 10gR2 RAC production environment on site A and a 3 node Oracle 10g RAC standby environment on site B. Both use like HW and OS - HP BL45p with RHEL AS 4.x.
Can we have heterogeneous standby databases(logical and physical) running on the same RAC nodes?
Can the 2 apply processes (MRP-manageed recovery process & LSP-logical standby process) coexists on the same set of nodes in a cluster at the same time. Are there any conflicts or limitations?
Is there any documentation that supports this?Would Active Data Guard give you the best of both worlds?
The caveat might be your SID_LIST_LISTENER setup.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(PROGRAM = extproc)
(SID_DESC =

(ORACLE_HOME = /u01/app/oracle/product/11.2.0)

(SID_DESC =
(global_dbname = <database2>_DGMGRL.yourdomain)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(sid_name = <database2>)
I have a server with ten standbys on it currently and no issues.
As long as the version is the same you should be good. -
Issues while Add / Delete RAC Node in Oracle 10g R2
Hi,
I have an requirement to add a New Node in the existing 2 Node RAC at Production, where 1 Node is Active & other one is passive due to licence issue & cannot keep both the nodes as active. Due to performance issues (Memory , CPU Cores ..etc) we are adding another new node.
Right now we are planning to add a 3rd database node making the new node as active and current active one as passive which is a swap & later on after final observation delete and decommission the current passive node.
This activity is checked at the Dev database with the same infrastructure (OS + Memory ..etc) but want to check what is the best approach (or) challenges we face during the RAC Node Addition / Deletion
RAC DB Version : 10.2.o.4
OS Version : RHEL 5.8
(1) Is the approach is right one , First Adding the node & later on delete
(2) If the approach is the correct , what would be the behavious of the 3rd node in means of active (or) passive
(3) We have taken RMAN backup , OS backup , CRS , ORACLE_HOME , ASM_Home backup , OCR & VD.
(4) Could you please give detail steps for adding / deleting node in 10g R2.
(5) Are they any known bugs to us with the DB release (or) OS while performing this activity.
Since this is a production machine we want to more proactive . Please correct or add any thing i am missing out ...
With Thanks,
RakeshHello Rakesh,
Please follow the following steps.
Node Addition Steps
1. Install and configure OS and hardware for new node.
2. Add Oracle Clusterware to the new node.
3. Configure ONS for the new node.
4. Add ASM home to the new node.
5. Add Databse home to the new node.
6. Add a listener to the new node.
7. Add ASM instance to the New Node.
8. Add a database instance to the new node.
Details of steps
1. run cluvfy to verify whether New node is ready for addition or not.
$ cluvfy stage -pre crsinst -n node2
2. from node1, execute
$/u01/app/crs11g/oui/bin/addNode.sh
3. Specify node2 vip address and follow instructions.
4. In the last of installtion it may through an wornig and will ask to click on YES. click on YES
5. from node1,
/u01/app/crs11g/bin/racgons add_config node2:6200
6. from Node1,set ORACLE_HOME=ASM_HOME and then execute addNode.sh from $ASM_HOME/oui/bin and Follow instrusctions.
7. From node1, set ORACLE_HOME=DB_HOME and then
/u01/app/oracle/product/11.1.0/db_1/oui/bin/addNode.sh
and Follow instructions.
8. from node2 start NETCA and configure listener for new node. While configuring Listener select the name of new node.
9. from node1 start dbca from ASM Home to configure ASM instance for new node.
10. Again from node1 start dbca from DB Home to add DB instance
Node deletion Steps
1. Delete the Database instance on the node to be deleted.
2. Clean up the ASM instance.
3. Remove the listener from the node to be deleted.
4. Remove the node from the database.
5. Remove the node from ASM.
6. Remove ONS configuration from the node to be deleted.
7. Remove the node from the clusterware
Details of Steps
1. Remove database Instance of node2
Dbca -> instance Management -> delete instance -> password for sys -> select node -> finish.
2. Stop asm for node2 from any nodes.
$srvctl stop asm –n node2
3. Remove asm for node2
$ srvctl remove asm -n node2
4. Remove Listener from Node2 using NETCA.
5. From Node2:
./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=node2" -local
6. From Node2, start runinstaller from Oracle_DB_Home/oui/bin, and remove "DB_HOME"
$ ./runinstaller
On the WELCOME Screen -> Deinstall product -> Select dbhome name (OraDb10g_Home1) -> Remove
7. From Node1:
./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=node1"
8. From Node2, set Oracle_Home to asm_1 and then fire:
./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=node2" -local
9. From Node2, start OUI and deinstall ASM Home.
10. From Node1, Set ORACLE_HOME= /u01/app/oracle/product/11.1.0/asm_1
11. From Node1: from /u01/app/oracle/product/11.1.0/asm_1/oui/bin, start OUI
./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=node1"
12. From Node2: as a root user (#) execute rootdelete.sh from /u01/app/crs11g/install
# /u01/app/crs11g/install/rootdelete.sh
13.From Node-1 first find out the node numbers
# /u01/app/crs11g/bin/olsnodes -n
output : node1 1
node2 2
14. From Node-1 as a root user (#):
# /u01/app/crs11g/install/rootdeletenode.sh node2[Node_Name] 2[node_no]
output:
CRS nodeapps are deleted successfully
clscfg: EXISTING configuration version 4 detected.
clscfg: version 4 is 11 Release 1.
Node deletion operation successful.
'node2' deleted successfully
15. From Node2 set ORACLE_HOME=CRS_HOME and then execute
$$ORACLE_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=node2" CRS=TRUE -local
16. ./runInstaller and remove CRS_HOME
17. From Node-1:
$ /u01/app/crs11g/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=node1" CRS=TRUE
18. check node is deleted from ./crs_stat -t -
Pointing existing RAC nodes to a fresh Shared Storage discarding old one
Hi,
I have a RAC Setup with the Primary Database on Oracle 10gR2.
For this setup, there is a Physical Standby Database Setup (using DataGuard configuration) also with 30min delay.
Assume that the "Shared Storage" of the Primary DB fails completely.
In the above scenario, my plan is to refresh a "fresh" shared storage device using Physical Standby Database Setup and then "point" the RAC nodes to the new "Shared Storage".
Is this possible?
Simply put, how can I refresh the Primary database using the Standby Database?
Please help with the utilities (RMAN, DatGuard, other non-Oracle products etc.) that can be used to do this.
RegardsDoes following Shared Device configuration is fine for 10g RAC on Windows 2003?
. 1 SCSI drive
• Two PCI network adapters on each node in the cluster.
• Storage cables to attach the shared storage device to all computers.

Migration from Single Node to RAC Node
Hi,
We are planning to migrate the Database from Single-Node to RAC Node. Are there any checklist list to be considered regarding Performance, System and Database ( or any other topic), before migrating to RAC.
ThanksIf it is already the same version, you will need to focus any "single-threadedness" of the application like sequences that are mandatory sequential, "semaphore-style" locking etc...
My experience is that going RAC and in particular to ASM can give a performance boost. If it is the same version (11gR2 for example) then any statistics-related performance issues will still be there. -
Huge number of idle connections from loopback ip on oracle RAC node
Hi,
We have a 2node 11gR2(11.2.0.3) oracle RAC node. We are seeing huge number of idle connection(more than 5000 in each node) on both the nodes and increasing day by day. All the idle connections are from VIP and loopback address(127.0.0.1.47971 )
netstat -an |grep -i idle|more
127.0.0.1.47971 Idle
any insight will be helpful.
The server is suffering memory issues occasionally (once in a month).
ORA-27300: OS system dependent operation:fork failed with status: 11
ORA-27301: OS failure message: Resource temporarily unavailable

RAC node process using 25% physical memory
We have a QA server is non-RAC, and production is two-node RAC. We have a migration app that does an INSERT from SELECT over 2 instances. All of the machines have been in successful day-to-day use for several months...our only troublespot seems to be the migration app.
Today we started the app on the QA server and watched the oracle processes using top. They ran normally and finished without any problems.
The same app started on either of the RAC nodes produced process memory errors and died.
As the app ran, there was a process reading the data from the source instance and a process writing to the target instance. We confirmed this by querying the session data. It doesn't matter which of the nodes runs which target process...the result is the same.
The reading process(session) on the source instance seems to run normally. The write process on the target instance, however, begins slowly accumulating memory in about 16M chunks and holds on to them.
We saw this in the RES and in the MEM columns of top. The target process never released any memory, but slowly grabbed it until its
RES was 4GB and the %MEM was about 30%. The app then died with process memory error. This is reproducible over several runs.
( Per Metalink Note 567506.1, the recommended value for Linux 64-bit is 4294967295 ..we have that set. )
There are other oracle processes and instances running on both nodes which do not seem to be affected. The total number of processes on each machine is around 750..much lower than the nprocs ulimit of 63K.
These process are both oracle sessions spawned by the app.
I haven't seen any info on the web or Metalink that matches these symptoms, so I thought I'd try the experts.
Why would the write session continuously use up physical memory, but only on RAC nodes?
We are running RHEL5 on Dell Poweredge 2950 w 16K Physical mem. Version of 10g is R2.0.4.user12017889 wrote:
The write process on the target instance, however, begins slowly accumulating memory in about 16M chunks and holds on to them.Exactly what process is this? An Oracle server process? Dedicated or shared server?
We saw this in the RES and in the MEM columns of top. The target process never released any memory, but slowly grabbed it until its
RES was 4GB and the %MEM was about 30%. How does the writer process work? Does it use PL/SQL? Does it use bulk processing? How does it call the reader process? Or does the reader process call it? Is this over a database link.
The app then died with process memory error. This is reproducible over several runs.If this is an Oracle server process, then there should be an entry in the alert log of the instance that recorded the crash and includes the name of the trace file generated by the crash. -

as i said befor, the machine always restarting
anyone have an idea?? pleaseDear All,
I recently upgrade the Few RAC setups with Oracle 10g Patchset 3 (10.2.0.4) on Linux Servers
In one of the RAC setup, found servers are rebooting daily. The same setup was working fine and problem started only after applying the Patchset. Checked all the logs and Found nothing relevant.
Then i checked the things which added with this Patchset.
The Most interesting found , Oracle Added a New Daemon- oprocd.
# ps -efl | grep oprocd
4 S root 6440 6063 0 -40 - - 2114 - Mar03 ? 00:00:00 /opt/oracle/product/10.2.0/crs/bin/oprocd.bin run -t 1000 -m 500 -hsi 5:10:50:75:90 -f
These are Interesting Points about above line
1.This Process is running by root user
2. With Highest Priority -40
3. Probing every Seconds (t 1000)
4. waiting CPU response for 500 Milliseconds ( -m 500 means margin time is 500 Milli Seconds)
5. Process status is Fatal (-f)
Now I am concluding these points- This daemon will probe cpu every second and wait for response within 500 Mill seconds. If in the 500 Milli second not getting any response from the cpu, will assume the CPU is hang and try to Reboot the Machine. The OPERATING SYSTEM will not get enough time to write the system logs and server reboots.
So the solution is increase the Margin time for 500 Milli second to 10 seconds.
These are following steps to increase the Margin time.
Please Remember- The Modification process need Downtime and You need to stop cluster service in all member nodes.
1. Stop The CRS Process
#crsctl stop crs
#<CRS_HOME>/bin/oprocd stop
2. Ensure that Clusterware stack is down and not running
#ps -ef |egrep "crsd.bin|ocssd.bin|evmd.bin|oprocd"
This should return no processes.
3. From one node of the cluster, change the value of the "diagwait" parameter to 13 by issuing the command as root:
#crsctl set css diagwait 13 -force
4. Check if diagwait is successfully set.
#crsctl get css diagwait
5. Restart the Oracle Clusterware on all the nodes by executing:
#crsctl start crs
(Note- If facing any problem to restarting the CRS services, ASM and Database, You can reboot the Nodes.The Cluster and Database will come automatically due to init startup scripts.)
6. The oprocd daemon process will show with -m 10000
# ps -efl| grep oprocd
# 4 S root 6440 6063 0 -40 - - 2114 - Feb02 ? 00:00:00 /opt/oracle/product/10.2.0/crs/bin/oprocd.bin run -t 1000 -m 10000 -hsi 5:10:50:75:90 -f
Rollback Procedure-
If You need to unset oprocd value due any reason
#crsctl unset css diagwait
I am confident, The abnormal RAC Node restart problem will solve with this workaround.

Sumit
