I get the following output for node connectivity check as part of pre clusterware installation checks.oracle@cps-oracle-1.homer.com% runcluvfy.sh comp nodecon -n cps-oracle-1,cps-oracle-2 -verbose
Verifying node connectivity
Verification of node connectivity was unsuccessful on all the nodes.
The above output i get for node connectivity component check. I pinged each public and private interface on node and found them to be working.The CRS is for Oracle10Gr2.
Oracle VM 2 Node RAC cluster Oracle 11G 11.2.0.3.0 Oracle 11g rel 2 GI
on current 2 node cluster we have GI and RAC db configured Nodes: vmorarac1,vmorarac2
we shutdown vmorarac1 to clone it to vmorarac5
on new node I have changed the hostname to vmorarac5 In /etc/sysconfig/network-scripts/ifcfg-eth0 change ip to new ip and same for /etc/sysconfig/network-scripts/ifcfg-eth1 152.144.199.210,152.144.199.211
mad echanges to /etc/hosts on vmorarac1/2 for 2 new IP address assigned to vmorarac5
I believe, in a multiple RAC Physical Standby nodes only one node applies the archivelogs to the standby database. How you can find which node is the APPLY NODE using a SQL query?
I know you can veiw this information by querying the standby configuration using DGMGRL but how would you find out this information from a remote client using SQLPlus/PLSQL?
We have oracle database 10g(10.2.0.4) running on AIX 5.1. we have installed 2-node RAC on another server AIX 6.1 . Now we want to migrate our single node database to new 2-node rac environment. how we can move/migrate/cluster-aware our single node database to 2-node rac?
I am installing Oracle 10g Clusterware in RHEL 5 Server. When i run root.sh in the second node the last step Running vipca(silent) for configuring nodeapps failed. Then i run VIPCA manually in second node and configured vip configuration successfully,but when i checked the post-checks for cluster services the Checking existence of VIP node application,Checking existence of ONS node application and Checking existence of GSD node application in second node failed. I am able to ping both the servers one another with vip name successfully and the CSS,CRS and EVM appears healthy in both nodes. 1. Does the vip configuration is proper? If no what is causing this error and how to rectify it? Find the output below
I would like get more details about single node RAC.. What is single Node RAC?..
1). just configure only one server instead of two node... same RAC installation.. cluster installation and shared disk configuration in single server itself.. in future we can add node to this ... 2). in 11gR2 having new feature Single Node RAC.. Multiple instances running on same node and configure using Cluster...
is there any advantage using single node rac(other than online upgrade to full RAC).

my attempt at verifying the TAF is working.
SQL> run 1 SELECT MACHINE, FAILOVER_TYPE, FAILOVER_METHOD, FAILED_OVER, COUNT(*) 2 FROM GV$SESSION 3* GROUP BY MACHINE, FAILOVER_TYPE, FAILOVER_METHOD, FAILED_OVER

so it looks as thought the sessions are failing over, but my app guy says he get a few errors during the process.. i need it setup to move the current query over without returning an error.. do i not have this setup properly?
I'm trying to add the third node to my existing two node cluster. In fact i succeded adding the node but i have the following problem:
-when i start node 1 and 2, everything is ok, but on node 3 startup one of the other nodes fails -this happens in any combination: start 1 and 3, everything is ok. when i start node 2, node 3 fails
The asm configuration (disks, permissions, etc) is the same on all three nodes.find below the asm and crsd log details from the failure time:

I need to verify huge number of records in two different databases. Basically i wanted to check if same record exist in other database's table or not? but as the number of records are more than billions who would i verify?
checking record one by one would be so hectic and time consuming. any other option is there?
Application team requested hosting team to add some space to tablespace as it was exceeding 80% used.Now the hosting team have added the space as per recommendation and the application team wants us to verify if the space was added. How to check the space was added in GB to list of tablesapces ?
I've created a password verification function (verify_pwd) in a schema which is not in SYS, but an equivalent of SYS. However, the problem arises when I'm trying to create a profie (MAIN_PROFILE) with the following attributes :
I have a staging table with 70 million rows and nearly 90 columns. We just want to verify and perform some validations on the data and then move this data to final tables. There staging table has a primary key in it.
We are planning to create the final table in following ways.
1. Create n number of final tables. 2. Create n number of final tables with partitions based on the primary key value in staging table. 3. Create single final table with partition based on the primary key value staging table.
How do i check in Table B whether it is converted correctly into words taking input or reference from table A
Consider below example:-
Table A Table B $125 Dollar One Hundred twenty Five only $45,542 Dollar Forty Five Thousand Five Forty Two Only $145.56 Dollar One Forty Five and fifty six cents Only $145,253 $35,256.65 $560,250.67
In the link below [URL] Thomas kyte has said, use the CBO and select /*+ FIRST_ROWS */ primary_key from table where rownum = 1; it'll read the index and stop at the first row. very fast on a big empty table (as the index is small and empty).
very fast on a big full table as the index is just read to find the first leaf node and then "stop".
It gives faster result if the primary key is used. But what if we have a table with around 1000 million rows and for the predicates there is a index range scan on the table.
What if we have a table say big_table (10000000000 rows) and the sql is something like
select /*+ first_rows */ 1 /* id, attribute_id*/ from big_table where attribute_name ='Gross Premium' and value ='10000' and version_date is null and rownum=1; --it's taking around 3 min
We observed that in such case there will be a range index scan for the index on the predicates. For a particular id there may be different values for attribute 'Gross Premium' and may have multiple versions.
How I would tune such a query where the purpose is to check if at least 1 records exists in the table for the input?
What are the steps required to change an ORACLE stored procedure (on a AIX/UNIX machine) using OTG to connect to a DB2 database, to an ORACLE stored procedure that uses ODBC or JDBC connectivity?
All I need to do in the stored procedure is a simple insert statement into a DB2 table.
What kind of ODBC/JDBC driver do I need on the UNIX machine? unixODBC?
What would be different in the ORACLE stored procedure for it to use ODBC connectivity rather than OTG.
I would like to develop a system with Oracle 9i as the database and PHP 4/5 as the front end. I am not able to establish the connectivity to the database. What should I do now ?
select from the postgre databse works just fine (however when i select data column alone it returns as date, if i select it together with som condition in where clause it returns varchar).
-- this runs ok select t."idbill", t."idpoint" from "crm"."bills2points"@dl_carecloud t ,"crm"."bills"@dl_carecloud brg where 1=1 and t."idbill" = brg."idbill" and t."idbill" = 9685; [code]....
I am currently using Oracle 10.2.0.1 version, in a single PC (test server) and MS-Access (2003) in it.
I was trying to use the logic of HS ODBC connectivity, but when i try to select the table from the MS-Access i am getting the following error.
"ORA-12154: TNS:could not resolve the connect identifier specified".
to create the successful connection between the MS-ACCESS and ORACLE. I just need to read some data from MS-ACCESS on a monthly base from a particular table.
I am trying to configure HS for Excel file. I am getting following error:
SQL> select table_name from all_tables@ODBCEXCEL; select table_name from all_tables@ODBCEXCEL * ERROR at line 1: ORA-28513: internal error in heterogeneous remote agent ORA-02063: preceding line from ODBCEXCELHeres my setup: [code]....
I need to verify if the current date is grater than the 15th of the current month. If its grater than the 15th of the current month i need to do an action or if else its lesser than 15th of the current month i need to do an other operation.
we have a database available in UNIX machine A which can be connected from client in UNIX machine B through port 1521. If we give ping command from UNIX machine A to B or B to A, 0% packet loss, means connection established properly through firewall in port 1521.
Now we are setup one more UNIX machine C and installed a client here. This machine is available in different group, means if i give ping command from machine C to A, 100% packet loss. But from machine A to C, connection established with 0% packet loss.Because of this, when we tried to connect to a database from client in Machine C to database in Machine A, we got "time out" error.
My query is: 1. Is this because of not opening of port 1521 through firewall? 2. If so, is it enough to open port 1521 through firewall when we connect from machine C to A? 3. Any additional setup is required in firewall apart from opening of ports?
