Is OAE H-A? Can it sustain a database crash?

A recent database crash caused HTMLDB 1.6 to crash, showing "Service unavailable" even after the database was back up.
Is it designed to sustain a brief database outage? Can it be configured to recover, failback, failover, without a restart of the application server? We are running htmldb on oAS 10.1.2. The J2EE part is designed to use DataSource that retries the connections and therefore can sustain a connection outage.

HTML DB does not need/utilize Oracle Application Server. All it needs is Apache and the database.
It is as H-A as Oracle itself since it "lives" inside the database.
If your database goes down, HTML DB goes down. When the database comes up, HTML DB is back up. [Provided, of course, Apache is up and running all the time]
Not that I don't believe you, but when you got ""Service unavailable" even after the database was back up", what did the Apache logs show?

   Why I create new Restricted KF and calculated KF for bw query, QAAWS,WEBI are can't return ok datas for new Restricted KF and calculated KF ?
I create KF on Universe :

Managed Server can not connect to Database

I have a WebLogic cluster with three managed Server on 3 different machines.
ManagedServer_1, ManagedServer_2, ManagedServer_3 (on Machine 3)
Firstly, everything is ok. But when we changed some configuration on Firewall and make the WebLogic cluster could not connect to database. 3 servers change status from Running to Warning. Then, we undo all the changes to the Firewall configuration. 3 Servers could connect to Database again but still in warning state.
It is strange that when I tried to restart ManagedServer_3. That server could not be up normally. It went to Admin state and all the datasources and connection pool could not be created. I tried to restart the machine 3 and start the server but it still failed to make server running normally.
( I made the test connecting to Database from Machine 3, everything is okie, I can got data from database, port 1521 opened )
Has anyone got the same problem and how to fix it? Is that the problem with the admin server?

JDBC DataSources/Connection pools are all at Domain Level. All we do is just target the datasources to AdminServer and Entire cluster (this will take care of all managed servers in the cluster). From Weblogic Console, TEST the data sources for any firewall issues. If this works from console, check from where you are accessing the Console like within the Firewall, that can access the database server. Even though the actual application is deployed only on cluster, still I would recommend targetting the datasources to both AdminServer and Cluster.

Can't mount oracle database on linux system

This is same as previous posting just added
e-mail and username info fo forum posting.
I am not able to mount an Oracle database.
I am new to Oracle and am working on an Oracle8i installation on an
Intel Linux Suse 6.3 platform. I am using only one harddrive and am
not using the 4 mount points as mentioned for efficiecy purposes in
the Oracle documentation..I am using the installation cd from Oracle8i
for Linux Starter Kit by Oracle Press. If anyone has this book they
can refer to pages 41-44 for the examples I followed.
As sysdba in sqplplus using the STARTUP command I can not Mount the
database -step 2 of the 3 stage process (Start, Mount and Open the
database) of opening an Oracle database.
I show the errors I encountered when I did the first 2 of the 3 steps
in the step-by-step mode (STARTUP NOMOUNT pfile=, ALTER DATABASE
MOUNT) in the sqlplus session and alert log respectively with startup
nomount and alter database mount for this sqlplus session.
Additionally I show the init.ora file lines referring to control file
which seem to be referred to by the sqlplus error messages and the
alert.log file. Perhaps some can give me some advice as what I can try
to fix this problem.
At the end of this e-mail I added several questions I had in regard to the control
files. Any help is appreciated.
Well, here are the sqlplus session results and its alert.log file:

init.ora control files
# define two control files by default
control_files = (ora_control1, ora_control2)
Here are my control file questions:
I need to know several points:
1) What are control files susposed to
contain and how would I recognize them?
I used the
unix find /usr/oracle \*ctl* -print
command to locate files with a ctl extension.
This resulted in about a dozen such files in
different directories as shown below:
./bin/lsnrctl
./bin/extractlib
./bin/agtctl
./bin/oidctl
./bin/lsnrctl0

2) On page 100 in the book Oracle 8i A Beginners's
by Oracle Press mention is made of a
CREATE CONTROLFILE command that can under
circumstances be used to re-create a control-file.
but that is all that is said about it. Perhaps
you might know something more about it.
3) Would you recommend any good text for
Oracle DBA's, especially for the problem of the sort
that I am encountering?

It's probably not supported on RHEL5/Centos5/etc., but...
You can get the installer to function using the following steps:
- extract the cal_linux_*.tar.gz, and cd into the OracleCalendar_inst directory
In there is the actual installer, cal_linux.
- the cal_linux is shell script wrapped around some binary blobs. The installer's
problem is that Oracle is setting the LD_ASSUME_KERNEL=2.2.5 environment
variable, which is a mistake on RHEL5. You need to make it not set that variable,
but you need to do so in a way that the size of the shell script does not change at all,
and none of the binary blobs are impacted.
- the approach I took was
mv cal_linux cal_linux.BAK
sed -e 's/LD_ASSUME_KERNEL=2.2.5/LD_ASSUME_KERNEL= /g' < cal_linux.BAK > cal_linux
chmod a+rx cal_linux
cal_linux -i gui
Note: you must have exactly 5 spaces in the substitution part of the sed command, because you're replacing 5 characters (2.2.5), and the size of the shell script must not change.
If you do that, the installer should run (one warning from awk still) and you should be able to install the product.

Can we use different Databases (Oracle & SQL Server) in one report?

Post Author: venki5star
CA Forum: .NET
Hi there.
Can we use different databases (Oracle & SQL Server) in a same report?
If possible how?
Another question,
Can we change the Provider Name at runtime of the given report. If so the above question is useless...
Thanks in Advance.

I tried this using Oracle Provider for OLEDB (the one that supplied by Oracle Client) and Crystal Reports 9. you can drag the column into designer but the image does not appear in preview.
I guess it's because CR does not recognized it as image, and there are no information that the blob data is an image at all.

I build databases with appleworks over 10 years on my ibook, and continue to add to them. Now I have a macbook pro. How can I translate the databases to a compatible program?

Over 10 years I have built several databases with Appleworks. Now I have a macbook pro. How can I translate these databases to a 10.6.8 program?

Thanks Joe, but that won't work. I've finally found a site that answers the question: http://www.wilmut.webspace.virginmedia.com/notes/aw/page1.html
I can only say that by Apple I have been royally screwed. I'll never buy another mac -- everything I do would simply disappear into cyberspace.

How can I use two database in Dataset in SSRS?

Hi,
I am using one query to generate my SSRS report. In that query I am using subquery. Now I am pulling data from multiple tales.
DB used in sub query is different than the rest of the tables DB.(So total I am using 2 DB(Database))
So I see that in SSRS, I can connect query(In DataSet Properties) to one DATA_SOURCE only, how can I use other database which is I used in sub-query?
I have to move this SSRS into PROD and I can't hard code that sub-query's DB name in my query.
Please give me suggestion. Thanks!!
Vicky

In SSRS 2008 R2 you can use the Lookup function (http://technet.microsoft.com/en-us/library/ee210531.aspx ) and LookupSet function (http://technet.microsoft.com/en-us/library/ee240819.aspx
Depending on your security set up, you can reference a table in a second database on the same server using a three part name: database.schema.table. This is more likely to work for you if you wrap your SQL command in a stored procedure.

How can I convert a Database Handle from TestStand to LabVIEW?

I want to use a Database Handle (already created in TestStand by an Open Database step) in a LabVIEW-VI (called from TestStand) to connect it with the "Connection Reference" input of the "Easy SQL.vi"? If I use a directly connection via the "TestStand - Get Property Value (Number).vi" I get back the error message 4101 in LabVIEW. How can I convert the Database Handle?
Test Engineering

The TestStand database step types use the CVI SQL Toolkit to talk to databases. The handle that you are referencing is an internal memory location and not a actual handle that you can directly use. Currently as implemented the handle that is stored in a numeric TestStand property for the connection and the SQL statement are the handle values returned from the CVI SQL Toolkit. So for the connection handle, you could call the CVI SQL Toolkit function
DBGetConnectionAttribute (
int Connection_Handle,
tDBConnectionAttr Attribute,
void *Value);
and get the CVI CAObjHandle reference. With this you could then call the CVI ActiveX function
CA_GetInterfaceFromObjHandle(
CAObjHandle Object_Handle,
const IID *Interface_Id,
int Force_AddRef,
void *Inte
rface_Ptr,
int *Did_AddRef);
to get the actual ActiveX interface reference. This would have to be converted into a LabVIEW reference.
You may want to consider just using LabVIEW to open a new parallel reference only using the toolkit.

now i don't have any archive file. is there any chance to recover the database ?If no archive log files are available you can't recover the datafile.You need to have all the archives from the time of offline backup was taken till the system datafile is lost.

Can we rename the database name in oracle 10g

Hi,
Can we rename the database name in oracle 10g.
Please help

Yes as already said, using DBNEWID Utility can renamed the database name.
You can also take a look at the Oracle Metalink Note:429674.1 (Which was written by me) - Subject: How We Used the Oracle DBNEWID Utility to Change the Database Name

Oracle 11.1.0.6 - Can more than one database work of the same installation

I am in the process of setting up 3 production 11.1.0.6 databases in a RAC Linux RH4 environment (approx 40GB each in size), question is can I get all 3 databases to work of the one Oracle Database installation i.e. can all three separate database work of the same set of binaries and from the same Oracle_Home?
As far as I know the only items that will be different of those values in the tnsnames and listener files.
Thanks

Lets back up and clarify terms.
A 3 node RAC cluster has one (1) and only one (1) database. Three (3) instances but only one (1) database.
If you are talking about something else you need to be very clear in your description.
Assuming one database and three instances the listener and tnsnames files should be identical. And, as Oracle creates all of this during dbca installation, why is it a concern?

Hi all,
Can I use Other database as the repository, Sybase/SQL Server? Urgent!!!
And Can I use other database store business data and sync with lite?
Thanks ahead!!!

Jonathan,
No, it is not possible to use any other database than Oracle (8.1.7) or later .
Oracle Lite will only work with Oracle.
