Cannot Open Physical Standby Database Read Only?
Dec 7, 2010Suddenly I can't open any of my physical standby databases read only. Alert log snippet and trace files follow post. I'm running 9.2.0.1.0 on all hosts, which are running AIX 5.2. I've successfully opened all physical standby databases read only numerous times in the past. Is it possible that these standby databases cannot be switched over to primary should the need arise?
Here's how I typically open a physical standby database read only:
alter database recover managed standby database cancel;
alter database open read only;
Errors in file /ora/product/9.2.0.1.0/rdbms/log/icps1_ora_27382.trc:
ORA-00604: error occurred at recursive SQL level 1
ORA-16000: database open for read-only access

View 12 Replies View RelatedDatabase Scattered / Sequential Read And Async IO Waits
Nov 23, 2010We have a table (call it PROBLEM table) that varies between 60 and 100 million records from one data archival process to the next.The table has data from all 50 states and is range partitioned by each states unique code and has a primary key based on the following:
STATE the data is from
BMRK YEAR the year the data was last benchmarked
AREA location the data is from
SERIES industry the data is located in
YEAR the data was reported
MONTH the data was reported
DATA TYPE the type of data that was reported
ESTIMATE TYPE the type of statistical estimate that was produced from the data
REPORT ID report id unique to each state
REPT SFC state the reporter resided in
We have developed a job that will process data from other tables and create some statistics resulting in approx 2.2 million inserts, .5 million updates and .5 million deletes on PROBLEM table during each job run. Once this table is loaded another process (call this PROBLEM_PROCESS)takes off that reads this updated information to produce some statistical data that is stored in another table. This data is produced by summing anywhere between 2 and 5000 records per query from the PROBLEM table.Here is the query (call it PROBLEM_QUERY)
select round(sum(cm_value*sample_weight),3),round(sum(pm_value*sample_weight),3)
from matched_sample
where state_fips_code = :1
and area_fips_code = :2
and series_type_code = 'B'
and year = :3
and month = :4
[code]...
When we run this job it is very fast (20 minutes) until it gets to the PROBLEM_QUERY, at this point we get DB file scattered read waits, DB file sequential read waits and async IO waits and the job has run for as long as 2 days. When I look at grid, the PROBLEM query is doing a full table scan and ignoring the index.
Our systems people advised us to re-organize and re-index that data in the PROBLEM table after all of the DML and before the PROBLEM_PROCESS takes off. If we do this, it works and cuts our time down alot. However, the re-organize and re-index process adds eight hours to this process. Note: When we re-roganized the data we create a copy table on another set of table spaces and insert the data into the copy sorting the data on the primary key columns. After this we re-index the new table and drop the old table renaming the new table. When we do this later, we move the data back to another set of table spaces. So, we move the data back and for between table spaces A and B we can say.
We have Oracle installed on a M5000 server with Solaris as the OS the binaries and data files are stored on a NetApp Storage array(model 3160) of 500 1TB SATA 7200 RPM drives. However, there are 128 other databases on the NetApp filer as well.
IMO the array and the slow disks are the problem. I believe this because we are catering to the slow disks by re-organizing and re-indexing the PROBLEM table during each run. I don't believe this should be neccessary. We normally re-organize and re-index our data each week in our production system after many more transactions than this.
Our systems people state it is our application. Oracle Support tells us the statistics are out of date but have not answered us on why the statistics are out of date and the index is abandoned after 1 run.
Forms :: Read File From Unix (Database Server)?
Apr 15, 2010I need to develop a form which has to read and display the contents of a text file that is stored in the Unix system where the Oracle data base is installed. So basically its the database server and not the forms application server.
1. Create an external table for the file everytime when the form is loaded by dropping and re creating the table and base the data block in the form on that table and execute_query and display the contents.
2. I am confused whether to use webutil or utlfile packages to read from the file and display on the screen as the file resides in the database or Oracle server and not forms application server or client machine.
Application Express :: Conditional Read Only That Saves To Database?
Nov 27, 2012I have an item that does not save to the database.it is conditional read only based on the value in another column, when it is not read only it displays as a Select list.. then whatever is chosen triggers a dynamic action that sets other items.so setting it as a display only is not an option.
after upgrading from 4.0 to apex 4.2 this gives error: Session state protection violation: This may be caused by manual alteration of protected page...
the only workaround I have found is to set the Read Only to none, then create a dynamic action that conditionally sets the field to disabled..This works, but my problem with it is that it looks different than the read only..read only was Black Text and no textbox..disabled is a text box with greyed out text that is hard to read for some of the users..

PL/SQL :: Read Oracle 10g Tables To SQL Server 2012

I have another Windows Server 2008 R2 machine on the same network, with SQL Server 2012 on it. What is the best way to read Oracle Tables in SQL Server?

Or is the best way to export the required tables from Oracle (e.g. into csv format) and import them into SQL?

These form are running fine with users having DBA privelege. However other users this is failing.
We have also checked that with users not having DBA privelege we are able to read the data in the table within the form also. The query in the record group is very simple
"SELECT CODE,SHORTDESC FROM GENCODES WHERE CODETYPE='BS' AND CODE <> '00'"
All these forms were fine previously when database was on 10g.
Moreover there are many other fields where list of values are there and allthose are ruing fine.
I have also checked datatype and length in query as well as fields on the form
How Much Block Will Be Read From Disk When A Single Oracle Io Call Occurs
Jul 10, 2012The block size of my db(10gr2) is 8k, and the db is on the raw device file system on a aix machine.
OS block size is 512k.
How much block will be read from disk when a single oracle io call occurs? Which one is currect, 8K or 512K?
If the block size for a single io call depends on the os block size (512k), I think os block size need to be tuned for oracle block size (8k). If we use raw device file system, os level block size has no meaning?

Data Guard :: Apply Patches On Oracle Database With Logical Standby Database?
Apr 22, 2011I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site
