Oracle 10g RAC implementation running out of space

I have an Oracle RAC implementation setup on a Sun Storagetek 6140 for storage. I have allocated 100gb of space to Oracle but am constantly running out of space during operations. I know that i can allocate additional disk space using Common Array Manager for the Storagetek. How do i get ASM to recognize the fact that there is additional space available to it?

Hi buddy,
How do i get ASM to recognize the fact that there is additional space available to it?You have two options:
1- The first one is create a new LUN, configure it at the OS level and add the disk to disk group.
alter diskgroup add disk '<DISK_DEVICE_PATH>';
2- The second one is increasing the LUN size (if possible, of course) and resize the disk.
alter diskgroup <DISK_GROUP_NAME> resize disk '<DISK_NAME>' <NEW_SIZE>;
Hope it helps,
Cerreia

  • JDBC connection to Oracle 10g RAC periodically times out

    I've been banging my head against the wall for months now and can't figure out why this is and what's causing it.
    We have 6x CF8 servers in our environment. 3 of which work perfectly and the other 3 have the following problem. All 6 machines were installed at the same time and followed the exact same installation plan.
    When I configure Oracle RAC data source, some of the machines time-out connecting to Oracle from time-to-time.
    Config:
    Solaris 9 on both CF and Oracle
    CF8 Enterprise with the latest updater.
    Apache 2 (not that it's relevant)
    6 machines, load-balanced (not clustered), identical install and configuration.
    data source config:
    JDBC URL: jdbc:macromedia:oracle://10.0.0.3:1521;serviceName=dbname.ourdomain.com;AlternateServers= (10.0.0.4:1521);LoadBalancing=true
    DRIVER CLASS: macromedia.jdbc.MacromediaDriver
    The problem:
    Every few minutes, CF starts hanging requests that deal with a specific RAC only data source. After about 30 seconds, all requests bail and generate this error in cfserver.log:
    A non-SQL error occurred while requesting a connection from dbsource.
    Timed out trying to establish connection
    This happens with any RAC data source on the "bad" servers while the "good" servers don't have this problem. The "bad" server doesn't have any problems with direct (non-rac) Oracle data source.
    Already tried:
    Moving server connections around on a switch (rulling out bad switch port)
    Copying driver from the healthy server (but it's the same installer anyway)
    Changed from RAC to normal Oracle type data source - works perfectly. So at the moment I have 3 servers connecting to a specific oracle instance and the other 3 connecting to RAC.
    Tried googling and searching forums and even Oracle metalink - nothing I could see relevant to this.
    It's a shame that after spending a ton of money on CF8 upgrades and Oracle RAC, we can't really utilize fail-over on the database connection.
    Any takers?
    Thanks,
    Henry

    I have the following in my CLASSPATH:

  • Oracle Home running out of space

    Hi,
    I have installed oracle application server 10g and oracle 10g on an Linux server.
    Both products have been installed on the /oracle partition which is about 11GB
    The database control and data files have been setup to another partition /oradata.
    After a few months i seem to be running out of space on the /oracle partition.
    I think it might be due to some log files. Can anyone please give me ideas on which files I can safely purge on the application server home and database home to create some space on the /oracle parition
    Thanks

    hi Prativ,
    For oracle application server,
    The log files in the below three location can be purged,if you want u can take a backup of these older log files in another mount point before deleting
    1st $ORACLE_HOME/webcache/logs
    2nd $ORACLE_HOME/j2ee/OC4J_BI_Forms/log/OC4J_BI_Forms_default_island_1/
    Purge the default-web-access.log and server.log
    3rd $ORACLE_HOM/Apache/Apache/logs

  • Oracle server running out of space

    We have a linux(debian)server which has Oracle10g in it and it is running out of space now. So we decided to add some more disk space(adding a new hard drive in the same server). But if we want to add more data files how can I tell the DB to use the added disk space. Since all the data files are existing in /home/oracle/oradata/orcl and their tablespace (USERS) are in the old disk,is it possible to tell the DB to use the added disk.
    Please let me know if that can be done and how.
    Thanks in advance.

    Drop the tablespace. If you are sure you don't need it.

  • Problem with Oracle 10g RAC VIP network setting at Solaris 9

    Dear All,
    I have tried to set up a Oracle 10g RAC Release 2.
    With OS solaris 9, and 2 nodes.
    The nodes setting as the following:
    nodes 1:
    Public address: 172.16.0.121
    Private address: 192.168.0.121, 192.168.1.121 (dual path for heart beat)
    nodes 2:
    Public address: 172.16.0.122
    Private address: 192.168.0.122, 192.168.1.122
    And i have assigned two IP adress 172.16.0.131, 172.16.0.132 as the VIP address for the
    RAC.
    And the following is the /etc/hosts file:
    root@shk01 # cat /etc/hosts
    # Internet host table
    127.0.0.1 localhost
    # public address
    172.16.0.121 shk01 loghost
    172.16.0.122 shk02
    # heart beat
    192.168.0.121 shk01-priv1
    192.168.1.121 shk01-priv2
    192.168.0.122 shk02-priv1
    192.168.1.122 shk02-priv2
    # VIP address
    172.16.1.131 vip-shk01
    172.16.1.132 vip-shk02
    But when i run the command "$ ./runcluvfy.sh comp nodecon -n shk01,shk02 -verbose"
    it shows the error:
    ERROR:
    Could not find a suitable set of interfaces for VIPs.
    Result: Node connectivity check failed.
    I did try to add the VIP address on bge0:1, as i using bge0 for the public address.
    Both nodes i did using the same interface name for it.
    Anyone have idea for me to check out the error?
    Also, I have other question about the raw device.
    As there is option for setting for ASM or raw device. If choosing raw device, does it mean that it just need to
    format the storage disk but without newfs it? And then the Oracle program will able to handle it?
    Thanks,
    Xentar

    You don't seem to state categorically that you are using Solaris Cluster, so I'll assume it since this is mainly a forum about Solaris Cluster (and IMHO, Solaris Cluster with Clusterware is better than Clusterware on its own).
    Clusterware has to see the same device names from all cluster nodes. This is why Solaris Cluster (SC) is a positive benefit over Clusterware because SC provides an automatically managed, consistent name space. Clusterware on its own forces you to manage either the symbolic links (or worse mknods) to create a consistent namespace!
    So, given the SC consistent namespace you simple add the raw devices into the ASM configuration, i.e. /dev/did/rdsk/dXsY. If you are using Solaris Volume Manager, you would use /dev/md/<setname>/rdsk/dXXX and if you were using CVM/VxVM you would use /dev/vx/rdsk/<dg_name>/<dev_name>.
    Of course, if you genuinely are using Clusterware on its own, then you have somewhat of a management issue! ... time to think about installing SC?

  • Seeking a solid reccomendation concerning 10g RAC implementation.

    I need a solid recommendation regarding what hardware I should use for my planned Oracle 10g RAC environment.
    Currently, I am looking for both node and SAN recommendations.
    I also created a list of 11 questions that I need to have answered.
    Here is how this will be configured:
    3 Node Oracle 10g RAC
    Each Node will consist of:
    32Gb of RAM (minimum)
    Windows 2003 64-bit Enterprise (corporate standard, but I can go with Windows 2008 if I have a valid justification)
    74Gb RAID 1 (minimum)
    Dual 10Gb Ethernet NICs
    The SAN will consist of:
    750Gb-3Tb dedicated to Oracle
    10Gb Ethernet NICs
    Here are some of my general questions:
    1.) Are there any benchmarks or case studies that you are aware of that might help in the decision process regarding hardware?
    2.) Where should my backups reside (SAN or elsewhere)?
    3.) What margin should be added for SAN provisioning and waste (even if thin provisioning is implemented)?
    4.) My CIO has decided to direct me to go with 10GbE copper instead of fiber channel, what unplanned hiccups can I expect?
    5.) What are the caveats of running dual redundant SAN systems?
    6.) We are currently using DELL hardware for all other systems, however I do have the freedom to change the vendor for this particular project if I can state a valid business justification. Any other vendors out there that make a better SAN or Node solution than Dell/EMC?
    7.) How much local storage do I need on each node?
    8.) Can I utilize 1 node to run ETL during production hours without drastically affecting database performance?
    9.) Regarding the maintenance of this setup, are their any particular classes or training you would recommend? I am a seasoned Oracle DBA, but could use any specific training on the specifics of RAC and/or general performance.
    10.) Are there specific advantages in Oracle 11g RAC vs. 10g that would be worth the cost of upgrading our 1000+ 10g user licenses?
    11.) Are there any studies on the performance advantages/disadvantages of running Oracle 10g on Windows vs. Solaris (or any Unix)?
    I will consider all input of high value, so please let me know what you would recommend.
    Thank you for your time.

    please find answers that i know for some questions.
    1.) Are there any benchmarks or case studies that you are aware of that might help in the decision process regarding hardware?
    2.) Where should my backups reside (SAN or elsewhere)?
    => what is the backup method you will be using? certainly recommend RMAN (in addition to OS backups that you are planning to use) for block recovery, should there a block corruption.
    i would keep some copies on the SAN local and mirror to DR site too.
    3.) What margin should be added for SAN provisioning and waste (even if thin provisioning is implemented)?
    => do not suggest thin provisioning for production.
    how big the volumes are going to be? reason for asking the Q is, if the volumes are going to be in TB, percentages can be lower. please plan for 2 years atleast.
    4.) My CIO has decided to direct me to go with 10GbE copper instead of fiber channel, what unplanned hiccups can I expect?
    5.) What are the caveats of running dual redundant SAN systems?
    6.) We are currently using DELL hardware for all other systems, however I do have the freedom to change the vendor for this particular project if I can state a valid business justification. Any other vendors out there that make a better SAN or Node solution than Dell/EMC?
    7.) How much local storage do I need on each node?
    => have beetween 75GB to 100GB. hope you are going to have only ORACLE RDBMS and CRS software in here.
    please make sure that you rotate your listener logs and alert logs and regular removal of old .trc files older than certain number of days old.
    8.) Can I utilize 1 node to run ETL during production hours without drastically affecting database performance?
    => node usage will help from CPU standpoint only. what about the disk writes it is going to perform to the data files?
    9.) Regarding the maintenance of this setup, are their any particular classes or training you would recommend? I am a seasoned Oracle DBA, but could use any specific training on the specifics of RAC and/or general performance.
    => attend a 5 day course from Oracle. install RAC on own and play with it.
    10.) Are there specific advantages in Oracle 11g RAC vs. 10g that would be worth the cost of upgrading our 1000+ 10g user licenses?
    => did not compare, though installed 11g.
    11.) Are there any studies on the performance advantages/disadvantages of running Oracle 10g on Windows vs. Solaris (or any Unix)?
    => running on windows? please do not. used on linux a lot. pretty stable and solid. recommend to go with 10.2.0.4 or higher.
    hope the above will help.

    Hi all,
    I have a question about Oracle RAC and network interface.
    We're using Oracle 10gR2 RAC with two nodes on Linux Red Hat.
    Let's assume that the public network interface goes down.
    I would like to know what happens with existing connections
    on node with network interface with problems.
    Are connections frozen, actives?
    Can the users continue to use theses existing connections using the another node of RAC?If the interface is down? what do you think? All connections to this node will die. How does your application handle fail-over, does it attempt to reconnect or just have a complete application failure?
    You should spend some time in a test lab where you can test this stuff for yourself. Read the documentation and there are tons of sites out there that purport to have all of your RAC/TAF/FAN/FAF questions. - I would read and trust the documentation first.

  • Using Clob with TopLink 9.0.4.5 and Oracle 10g RAC

    I am trying to store an XML file in a Clob type field of a DB table using TopLink 9.0.4.5 and Oracle 10g RAC and need some guidance about how to do it. I got some directions to start it with the Tip "How-To: Map Large Objects (LOBs) to Oracle Databases with OracleAS TopLink" but still need some more helps.
    When using the Oracle JDBC OCI driver, the tip gives the code block for a Clob field:
    DirectToField scriptMapping = new DirectToField();
    scriptMapping.setAttributeName("script");
    scriptMapping.setFieldName("IMAGE.SCRIPT");
    descriptor.addMapping(scriptMapping);
    As I understand, TopLink creates instances of the Descriptor class at run time for each of the descriptor files and stores them in a database session, where is the proper place (in SessionEvent of TopLinkSessionEventHandler?) for me to get a reference to such an instance of my Descriptor class in Java code so that I can add the above mentioned additional Mapping? Are the above String values of "script" and "IMAGE.SCRIPT" predefined in TopLink API? Can I accomplish the same thing just using the TopLink Workbench tool instead? If yes, please advise the detailed steps to do so.
    The tip also states to call the following code in case of using Clob:
    DatabaseLogin login = session.getLogin();
    login.useStringBinding();
    Should the above 2 lines of code be called after the following lines of code?
    SessionManager sessionManager = SessionManager.getManager();
    Server serverSession = (Server)sessionManager.getSession("MY_SESSION_NAME");
    Besides the above extra coding for the Session and Descriptor Mapping, is there any special handling in between Data model and DB table mapping? Can I map a Java String type to a DB Clob field using the Direct-to-field mapping?
    Appreciate any help.

    Never mind ....... I had already figured it out .....

  • Oracle 10g RAC VMware support

    Is Oracle 10g RAC supported in a production VMware environment yet? If not, what is the hold up? VMware is the standard in the industry now and not being able to virtulize is both costly and not practical.

    As the previous responder points out, whilst Oracle does not actively certify its products in VMWare environments, it will provide support provided the issue is already known on the guest OS, or it can be reproduced outside a VMWare environment.
    I know of many organisations running VMWare with RAC, including my own although we tend NOT to use it in Production environments. Oracle has many resource management capabilities built in to the RDBMS and the Grid Infrastructure which only work well if Oracle has control of all of the resources on a server.
    I guess if you're not satisfied with our responses, you should direct your question to Oracle Support rather than this forum. Certification of VMWare is probably as much (or may be mostly) a business decision by Oracle and us Forum members can't generally explain those decisions.

  • Oracle 10g RAC installation on HP-UX 11.31 for SAP ERP 6.04

    Dear experts,
    We are trying to install SAP ERP 6.0 EHP4 with Oracle 10g RAC on HP-UX 11.31. Please note that, We are using VERITAS cluster filesystem (CFS) for this purpose and not HP-UX ServiceGuard ClusterFileSystem.
    *As per SAP procedure, we have installaed plain plain SAP system with single instance Oracle (ref: Configuration of SAP NetWeaver for Oracle Database 10gRAC guide). Now we are first trying to install Oracle Clusterware (CRS) and then we will install Oracle RAC software. Is this procedure right?*
    Which file (and its path) we have to use for CRS installation and its patch? Is it runInstaller under /oracle/stage/102_64/clusterware? With this file we can install CRS 10.2.0.1. Similarly for Oracle RAC, which files we are supposed to use, i.e for installation and patch upgrade?
    Also can we use clusterware package available from Oracle directly in the SAP environment?
    We tried to install CRS with runInstaller while running Configuration Assistant after root.sh script.
    The following commands are failing in Configuration Assistant:
    /oracle/CRS/102_64/bin/racgons add_config erpprdd1:4948 erpprdd2:4948
    /oracle/CRS/102_64/bin/oifcfg setif -global  lan1/20.20.20.0:cluster_interconnect lan0/192.168.3.0:public

    Those errors remind me on errors I encountered when I was trying to do installation that was not certified,
    so try to check if installation you are doing is actually supported.
    In the meantime , visit metalink and read document [ID 460969.1] , */usr/bin/ld: Cannot Find -lxml10, Genclntsh: Failed To Link Libclntsh.so.10.1*

  • Oracle 10g RAC

    Hi All,
    I am a research student currently struggling to install Oracle 10g RAC on Windows OS.What i understand about a Oracle RAC database system is that it involves a configuration of multiple hosts or servers joined together with a clustering software and accessing the shared disk structures.What i also understand is that i need a CRS provided by Oracle for a Windows or Linux based RAC installation.
    What i don't understand is for a Two node RAC system do i need a Third machine which has the shared storage device.If yes do i have to install a copy of Oracle 10g Enterprise Edition and CRS on the shared storage device moreover do i need to install a copy of Oracle 10g Enterprise edition on each of the nodes or just the clusterware is enough.

    Hi Salil
    No, you do not need a third machine. You can even setup RAC as a single node on one machine! What you do need is to have some sort of cluster aware file system. Try looking at OCFS on Windows in your case.
    If you are interested in a Linux example please have a look at the examples at http://ocpdba.net/oracle9i_rac/cheaprac.html and http://ocpdba.net/oracle10g_rac for an OCFS implementation I am working on.

    Any suggestion?

    You know its not certified?
    My first thought when I read the subject of this thread, and before reading what you posted, is that you've either done no research on RAC or didn't understand what you've read.
    You can create a RAC cluster using any operating system certified by Oracle.
    But the operating system is the least important part of creating a cluster. The questions you need to be able to address are:
    1. What is your solution to created shared storage?
    2. What is your solution to create the cache fusion interconnect and VIPs?
    If you don't have an answer to these questions you can not build a RAC cluster.

  • Oracle 10g RAC using ASM - Storage Issue

    I’ve an issue related to Oracle 10g RAC.
    I’ve 2 node cluster each being Dell 2850 Server with RHEL 4.0
    I’ve EMC CX300 SAN storage with following partitions
    /orasoft     10 Gb          OCFS2 File system
    /oracrs          2 Gb          OCFS2 File system
    /orabackup      100 Gb          OCFS2 File system
    The datafiles are on ASM which is not directly visible in OS.
    I’ve common Oracle Home installed in /orasoft/db_1 which is shared by both nodes in cluster.
    I’ve faced an issue recently related to EMC storage.
    The /orasoft partition displays 1.4 Gb space available using df command.
    With both nodes sharing the common Oracle Home (/orasoft/db_1), when ever I try to touch a file I get an error as No Space left on device. I’m unable to start any service with the same reason.
    Is this setup correct ??
    Can anyone help me with this storage issue ??

    Need a clarification here...what do you mean by "Storage System"...do you mean a server/node or the SAN storage system. If you are referring to a server/node's local storage, then it would NOT be possible for use by RAC, since the disk space has to be shared among the nodes.
    Here is what you can do:
    - Create two partitions/devices (for example Disk_1 and Disk_2) in the SAN storage
    - Create a ASM disk group which would mirror Disk_1 to Disk_2.
    Again, please note that the partitions have to be visible and be accessible read/write from both the nodes/servers.
