Data Guard :: Can VMWare Software Hold Two Servers
Aug 8, 2013
I wanted to practice dataguard in oracle. I feel that I can practice realistically if I have 2 different servers to do switch overs, building new physical standby database from scratch and shipping the archiving logs from primary to physical standby database, etc.,
Can I use VMWare software to install 2 different servers and then practice dataguard?

Is it possible to hold the data from select statement without temp table or materialized view or view in oracle?
because my DBA does not give access to create temp table.but we are selecting the records from 3 different sql statement.
Example: inserting in temp table
a) insert into temp select empno,ename,sal from emp where sal>4000 b) insert into temp select empno,ename,sal from emp where dept=40 c) insert into temp select empno,ename,sal from emp where comm is null
We have physical data guard configured version (10.2.0.4). We are in need to upgrade primary & standby database to 11G R2. Can we perform rolling upgrade.
I am providing the complete code and my exact requirement.
CREATE OR REPLACE PACKAGE INTERNAL_SCORING_RAM IS PROCEDURE TrendScoring_ram(pBUID IN STAGING_ORDER_DATA.BUID%TYPE, OrderNum IN STAGING_ORDER_DATA.ORDER_NUM%TYPE, ReturnValue OUT VARCHAR2);
[code]...
/In my code the procedure "trendscoring_ram" is calling "inserttrend_ram" procedure 70 times for different variable values. Instead of calling the "inserttrend_ram" procedure 70 times.
want to hold the values in a associative array , defining it in package and call that procedure only once.As below.
i have configured physical standby in my local system, to check logshipping i created a table at primary db, wen i tried to check in standby, it says table does not exist..below are primary & standby alert entries..
Primary alert log

Statspack has been configured for Active Dataguard on Primary database.We got an spike of Buffer busy waits for about 5 min in Active Dataguard, this was causing worse Application SQL's response time during this 5 min window.Below is what i got from statspack report for one hour

Why there could sudden spike of demand on UNDO data in Active Data Guard ?
I have error message when running duplicate : FRM-21011: PL/SQL unhandled exception ORA-06502..I'm trying to hold 4000 characters in a variable like what do below:
if s_str is NULL then s_str := eachcol.column_name||'{{'|| name_in(name_in('system.cursor_block')||'.'||eachcol.column_name)||'{{'; else s_str := s_str||eachcol.column_name||'{{'|| name_in(name_in('system.cursor_block')||'.'||eachcol.column_name)||'{{'; end if;
It's simple variable to hold value but still can't get by large string though.
I am working in a bank as an system consultant, i have a SAN Storage Area and oracle as below.
SAN 1
This interface includes the DATA FILES of the oracle tablespace
SAN 2
SAN1 Mirrors the DATA FILES of the oracle tablespace to SAN 2
1. Can i rely on real time data recovery from SAN2 ? 2. if SAN1 (Data Files are currupted) will the SAN2 Data Files will be currupted as well. 3. If the SAN2 is currupted then what Oracle Features can be used to have uncurrupted data.
i did everything writen but when i do *SQL>alter database recover managed standby database disconnect from session;*
i go and look in the standby database AlertLog file ,and thats whats writen
*ORA-01157: cannot identify/lock data file 1 - see DBWR trace file ORA-01110: data file 1: 'F:ORACLEPRODUCT10.2.0ORADATADBSYSTEM01.DBF' ORA-27041: unable to open file OSD-04002: غير قادر على فتح الملف O/S-Error: (OS 3) The system cannot find the path specified.

strange thing that it realises the primary database in drive F and it goes to it but i dont understand what could be the reason of this ,although im doing this command while primary database is shutdown!
I configure logical standby online .when I execute dbms_logstdby.buid,first
SQL> EXECUTE DBMS_LOGSTDBY.BUILD;
it was blcoked by other sesson,then i kill the holding session,but no work.then i cancel this step and execute it again . the error is
SQL> EXECUTE DBMS_LOGSTDBY.BUILD; BEGIN DBMS_LOGSTDBY.BUILD; END; * ERROR at line 1: ORA-01354: Supplemental log data must be added to run this command ORA-06512: at "SYS.DBMS_LOGMNR_INTERNAL", line 3669 ORA-06512: at "SYS.DBMS_LOGMNR_INTERNAL", line 3755 ORA-06512: at "SYS.DBMS_LOGMNR_D", line 12 ORA-06512: at line 1 ORA-06512: at "SYS.DBMS_INTERNAL_LOGSTDBY", line 370 ORA-06512: at "SYS.DBMS_LOGSTDBY", line 157
I have set up a cross platform (Microsoft Windows IA (32-bit) -> Linux x86 64-bit) data guard and it worked fine.Then I did a switch over (which again worked) and found out the data is not getting replicated at all.. checked the data files available from the new primary database and found out they are in the windows format as below..
SQL> select name from v$datafile;

and physically they were created at '/home/app/oracle/product/11.2.0/db_1/dbs/' and as
1) scn differs wrt primary in standby (i checked, 1day difference), how to make scn same?
2)i created a table in primary, its not refelecting in standby, (below i ve pasted alertlog entries)

Provide me the link for the download of AIX 32 bit operating system ISO file as I need this for VMWARE. I have searched the IBM sites for this but to no avail.
Our organization has recently decided to go for storage metro cluster solution for disaster recovery. In a Data guard environment, we normally calculate how much archive log is generating and based on that value we calculate the required bandwidth.
For storage metro cluster, we need to find how much block is changing in our primary database, and the same rate of change would apply on DR cluster. Now, i need to give the assumption how much changing is happening in my system. How to calculate the change.
I was making some page validation to APEX_ITEM manual tabular form. When every a validation executes it will clear all the data what user enters. What is the best method to hold the session values in APEX_ITEM.
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"
We have eight servers. One of them is for centeral management. The other seven is for development and test databases. Every night, we start a process which exports database schemas (without data) into the centeral server. An example of the process we run is just like below:
As you can see, we use @dev to connect remote database. But dump file is created in local (centeral) server. We are planning to use datapump instead of classic export in future. But I couldn't find a solution, that could take a database export in a remote server and create dump file in local. I have looked at NETWORK_LINK parameter; but it doesn't seem to work for our case.
Is it possible to backup a remote database with datapump and make it create dumpfile in local? (Of course we can use some solutions such as NFS, but we really not prefer this; if datapump has ability to remotly backup.)
only these two packages in my server. should i have to install oracleasmlib??

In current form, i use *pll file to pass Global.<variable name> to the form *.fmb
The problem is that if i copy a string of 4000 characters (which i need to) to Global.<variable name>, it will automatically cut a whole chunk to shorter string (less than 1000).
Is there a better way to that Global.<variable name> can hold 4000 characters?
why we seem to be unable to report against the ap invoice hold release date using Discoverer in Oracle 11.5.10? the person who wrote our current report used a decode statement to look at the last update date of the release lookup code to create a release date, but i am trying to recreate this in a different tool (Qlikview) and just wanted to understand why we seem to be unable to report on the field as is!
Is the 12c version of the Grid Control only for Oracle Cloud? Not completely sure of exactly what cloud computing is. Looks like a conglomeration of shared resources. Anyway we are converting all of our servers over to vmware virtual machines except the ones we manage in other states. I am upgrading each database to 11 r2 as we convert the servers. Anyway my Grid server is next to convert to a virtual machine. I am using Grid Control 10.2.0.5.0 now. I want to upgrade to the latest version of the Grid control. 12c seems to stress and boast about managing the "Oracle Cloud" to manage regular single node Oracle servers as well as vmware virtual machines?
I am working in a reporting project.We have different environments.After migration of data base script from one server to another we always need to crosscheck whether newly added columns have been properly migrated or not.
any database script to address the same thing. Last but not the least we have servers with TNS entries. how we can connect to different server while present in one specific server.
