Server Administration :: Configure Watchdog For Oracle DB 11g On Redhat Linux
Jan 28, 2011
I need to configure a watchdog (or any other) utility which will constantly monitor database health. And if something goes wrong with the database, the utility should restart the DB instance.
I have 9i RDBMS Software and RHEL 4. I want to install a Oracle Names server. I install RDBMS.But Where I run netmgr and want to configure and start Oname server it says.
$ORACLE_HOME/bin/names file not exists.
How Can I configure OracleNames Server using Oracle 9i On Linux.
We have 3 databases with version 10.2.0.3.0 running on RHEL AS 4.5 32 bit operating system. We are planning to move these databases to RHEL 64 bit Operating system.
let me know the highest 64 bit RHEL version supported by these databases(10.2.0.3). Will it support with RHEL 5.5 64 bit version?
A link which describe step by step with screen shots how can i install oracle 10 r2 on oracle linux server release 6.1 using vmware workshop 8.my actual os is windows server 64 bit in this in install vmware 8 and i install oracle linux server release 6.1 32 bit now i want to install oracle 10g r2 or oracle 11g r2 on this .
I am trying to configure a new ASM instance. I am getting error " -bash: crsctl: command not found" .. where should i actually look for the error. crsctl command not found.... I am doing this as a root user .
I'm new on 11g, due to my limit storage with mounted internal disk, so I think, may I can store archivelog in ASM without FRA? However, I did not find any document to verify.
If you want to upgrade these components, you must first install them, using the OUI, and then re-run the Upgrade Assistant. Do you want to continue with upgrade? Note: If you continue, the above components will not be considered as part of the upgrade process.*
Following is the status of the specified components from 11.1.0.6
COMP_ID COMP_NAME VERSION STATUS AMD OLAP Catalog 11.1.0.6.0 VALID SDO Spatial 11.1.0.6.0 VALID APS OLAP Analytic Workspace 11.1.0.6.0 VALID
Should I install these components while installing 11.2.0.2 patchset prior upgrading? I was unable to find any component installation on OUI.
Also DBUA pre-upgrade asked to remove existing UltraSearch from 11.1.0.6 prior upgrading. Though I removed it, but not sure is that going to hamper the upgraded DB, as I'm not sure of the usage of this component as well.
I've been following Metalink note 602952.1, 309815.1 and 605828.1
metalink note 602952.1 states Quote:Note: Keep in mind for ASMLIB disks you will need to use the /dev/dm-* disks instead of the /dev/mapper/mpath* devices since they are present in the partition table ==)> /proc/partitions and ASMLIB will look at that file during the disk discovering phase. If you do not use the disks located at /dev/dm-* then ASM will not be able to discover them. and to create ASM disks with Quote:/etc/init.d/oracleasm createdisk DISK1 /dev/dm-<disk><partition> Also further stating Quote:NOTE: When scanning, only the device names known by the kernel are scanned. With device-mapper, the kernel sees the devices as /dev/dm-XX. The /dev/mapper/XXX names are created by udev for human readability. Any configuration of ORACLEASM_SCANORDER or ORACLEASM_SCANEXCLUDE must use the dm prefix.My environment is RHEL5 and towards the end of the note it says Quote:Note: On release RH 5 the /dev/dm-N devices are not persistent, starting, these devices are no longer created by udev. So release RedHat 5 you can create the ASMLIB disks on the /dev/mpath/<partition> or /dev/mapper/<partition>
Therefore I created a ASM disk using /dev/mapper path and it is only visible on the node it was created. Even after scandisks on other node it is still not visible when listdisks/oracleasm-discover
I've also tried creating the asm disks with dm-12 option and the same, disk get created but not visible on the other node.
Moreover if I restart the oracleasm restart the disk disappears from the node that it was visible Quote:
[root@db2 ~]# /etc/init.d/oracleasm createdisk vol1 /dev/mapper/mpath6p1 Marking disk "vol1" as an ASM disk: [ OK ] [root@db2 ~]# ls -l /dev/oracleasm/disks/* brw-rw---- 1 oracle dba 253, 12 Nov 8 10:22 /dev/oracleasm/disks/VOL1 [root@db2 ~]# /etc/init.d/oracleasm scandisks Scanning the system for Oracle ASMLib disks: [ OK ]
[code]....
But disk lable is there and could be seen from both nodes on the same partition Quote:
head /dev/mapper/mpath6p1 VOL1ORCLDISKVOL1
My suspicion is on multipath configuration. I've tried both (not at the same time) combinations given below.
During installation of Oracle RAC 11g r1 on Linux using VMware server for Two Nodes, all the pre cluster installation test was successful, and execution of root.sh on node 1 was successful too, but whenever I run the root.sh script on the second node I get error message "Failure at final check of oracle CRS stack. 10"
I have Oracle 9i DB in windows 2003 server, I want to access this DB from Linux desktop. Is there any 'client software' is available to connect Or procedure to connect the DB.
How to configure Oracle EM with newly created Oracle Instance on Oracle 10g DB,which is Single Instance DB but not RAC ,when I start the Oracle EM it is starting the default DB which created during Oracle Server Installation.
We wish to configure an Oracle 11g RAC with ASM setup for the internal employee training purpose. The requirement is as follows
1. Operating system Linux, Software Oracle 11g Release 2 2. Need to build total 5 individual clusters. 3. Each cluster with 2 Node 4. Need to configure ASM as a shared storage with real hardware. (No virtualization, Openfiler, NFS) 5. Need to configure RAC database.
provide me the hardware details for configuring Shared storage. Is there any specific Storage which we can use to configure ASM as a storage.
I have a scenario In which I have say 4 AQ in which I will post the message.Also i have say 2 database.I am planning to create an MDB which will poll on these AQ's, so whenever I post message the MDB will read it and perform a specific action.I believe I can create only one MDB per queue, if it is so then I have to create 8 MDB.
As there 2 datasource and 4 MDB. Is there any other way to handle this I mean without creating 8 MDB as the Data sources can increase to 10 to 20 so the number of MDB will be 20 to 40.I guess this will affect the application performance. Can I make some changes in application so that only few MDB's are required?
i am trying to install 2 node RAC on Oracle VMs. Before the installation during the -preinst check there were few issues which were resolved (ex user equivalence). After that during the installation process of the Grid it failed at step "Configure Oracle Grid Infrastructure for a cluster". After it failed at this step, subsequent steps too failed which I asked OUI to ignore and then I ran both the post installation scripts. And then ran post crsinst which failed. Pasting below the output of the root.sh script, post crsinst and other checks.

We have to configure Dataguard for our 24x7 critical banking 2 Node RAC database(10.2.0.4). Before proceeding with the configuration we have to make sure what steps we should follow to have minimum or no downtime.
1) Document covering DG setup in RAC environment. 2) We have to perform switchover as well so need its steps too. Either the normal switchover steps would be used or have to stop/start rac services as well.
We want to configure HSODBC on HP-UX 11.23 for Oracle Database 10g R2 in order to establish a DB link from Oracle to Netezza.We have installed the ODBC Drivers too..Currently we have not done any configurations and we go via an AIX box to establish a link.We want to get rid of the AIX box and instead establish directl link towards netezza from HP-UX Box.
Does Oracle support have some guidelines or steps to setup HSODBC on Oracle database 10g r2 residing on HP-UX 11.23 towards Netezza?
I am importing some data from Oracle into another database on a regular basis. It works fine for most of the queries but couple of queries don't work sometimes (random). I don't get any errors or any data.
We switched on the Oracle auditing to find out the queries being sent to oracle db. We can see all the queries in the Audit log. Is it possible to configure Auditing to get the "Number of Rows" returned by Select statements so that we can be sure that some data was returned.
i am trying to install Oracle 10.10.2.0 on Windows Server 2003 standard x64 Edition Service Pack, but when i try to run the installer or open DVD it gives me below error.
"The image file D: is Valid, but is for a machine type other than the current machine."
I was trying to delete the database in the test server. When i was deleting listener was already stopped, i continued deleting using dbca, it shown me some alert that datafiles cant be deleted because system could't find database, since listner was stopped so only service was deleted(the one showing in the windows administrator toolsservicesOracleServiceTEST).
All the datafile parameter files are still there. How can i delete the datafiles and parameter files belongs to that database or how to create the deleted service, so that i will start the listener and do the complete deleting of the database.
I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server. 2. I invoked "sqlplus" from another unix box to login to the database. 3. I found that the process id (ps -ef |grep sqlplus). 4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID, SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM, SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID FROM SYS.GV_$PROCESS, SYS.GV_$SESSION WHERE SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST' and SYS.GV_$SESSION.MACHINE like '%hostname%'
