Oracle Names - Failing Over Databases

Is there a way to automatically redirect connections with Oracle Names when a database has failed over to its standby database?

How does fail-over database work

Hi,
I have two databases of oracle 10g running on linux and windows. I have to make one of these databasse as a failover database. What is the solution.
Oracle Fail Safe works only in microsft clustered server i.e mostly in windows environments.
What if the both the databases are from different os, then Failsafe doesnt work.
If anyone can suggest me the techonology for this kind of scenario, I would be very thankful.
Regards,
Prabhath

Thanks for the replies. What I have been able to determine from how we run our KKBC_HOE is that we run KKRC just for the current month. Then we run KKBC_HOE for the current month. The KKBC_HOE picks up all activity for the "actual" column that has occurred during that month. But the Target column only get poppulated if the order is marked DLV or TECO.
To measure overall performance you really would need to run this report over several months. Also, does anyone know if the target is taking the standard cost per unit X Planned order quantity or does it take Standard Cost X Actuall Quantity received?
Although there is a Target line based on the actual number of cases received it seems like the rest of the report is based on the Order Planned amount. I'm trying to figure out if we have all our switches set right for this report.
Thanks for your feedback.

Oracle Report Failing After Database Version Upgrade

Hi,
I have function code created in RDF file of oracle reports 10g as below-
create or replace function clobblobtest (TMP_MID varchar2) return varchar is
missed_text varchar2(1000) := '';
v_time_stamp date;
v_end_time date;
cursor c1(c_time_stamp in date,
          c_mid in varchar2) is
       select mn.TEXT from msgnotes mn
where mn.mid=c_mid
      and mn.create_date >= c_time_stamp;
cursor c2(c_time_stamp in date,
          c_mid in varchar2,
          c_end_time in date) is
       select mn.TEXT from msgnotes mn
where mn.mid=c_mid
      and mn.create_date >= c_time_stamp
      and mn.create_date <= c_end_time;
begin
IF ('1' = 'INWARD RETURN') then
    select bbi into missed_text from mtf1000 where mid=TMP_mid;
    ELSIF '1'='QPH Missed' then
Select max(nj.update_date) into v_time_stamp
from newjournal nj
where nj.mid=TMP_mid and nj.status = 'CTOVRQ';
for i in c1(v_time_stamp,TMP_mid) loop
missed_text:=missed_text||' '||i.text;
END Loop;
ELSIF ('Rejected'='Rejected' OR 'REJECTED'='REJECTED') then
IF ('TERMINATED' in ('TERMINATED')) THEN
Select min(nj.update_date),max(nj.ENDDATE) into v_time_stamp,v_end_time
from newjournal nj
where nj.mid=TMP_mid and nj.actionid2='16' and nj.actionid1 is null;
for i in c2(v_time_stamp,TMP_mid,v_end_time) loop
missed_text:=missed_text||' '||i.text;
END Loop;
ELSE
Select max(nj.update_date) into v_time_stamp
from newjournal nj
where nj.mid=TMP_mid and nj.status = 'UNSETLED';
for i in c1(v_time_stamp,TMP_mid) loop
missed_text:=missed_text||' '||i.text;
END Loop;
END IF;
ELSE missed_text := null;
END IF;
return(missed_text);
End;
Note:- Text column from table msgnotes is of datatype CLOB.
I have executed report having this function before oracle upgrade and it works fine.
But when i am trying to execute report after oracle version upgrade from 11.2.0.3.0 to 11.2.0.4.0 with same data report fails with runtime error Rep-1401: '' Fatal PL/SQL Error.
With New version we tried to typecast Text column from clob to varchar and executed report then it works... but report runs on old version without any explicit typecasting.
Please note when i run and call this funtion from sql developer with upgraded database version it works fine.
Please advise.

This error can possibly depend on the fact that the PL/SQL engines are in different versions. When using SQL Developer you use the PL/SQL engine in the database. When using Oracle Reports you use the PL/SQL engine in the Oracle Reports Server (Web Logic Server even maybe). These versions - in the Forms and Reports realm - are different (read: a lower version) than the PL/SQL engine in the database.
If I check what version I have in Oracle Forms, as an example, I get 11.1.0.7.0 (Help in the Oracle Forms Builder menu) but in the database I have (select * from product_component_version;) 11.2.0.3.0.
That COULD be your issue...how to fix it I am not sure...

Physical standby database fail-over

Hi,
I am working on Oracle 10.2.0.3 on Solaris SPARC 64-bit.
I have a Dataguard configuration with a single Physical standby database that uses real time application. We had a major application upgrade yesterday and before the start of upgrade, we cancelled the media recovery and disabled the log_archive_dest_n so that it doesn't ship the archive logs to standby site. We left the dataguard configuration in this mode incase of a rollback.
Primary:
alter system set log_archive_dest_state_2='DEFER';
alter system switch logfile;
Standby:
alter database recover managed standby database cancel;Due to application upgrade induced problems we had to failover to the physical standby, which was not in sync with primary from yesterday. I used the following method to fail-over since i do not want to apply any redo from yesterday.
Standby:
alter database activate physical standby database;
alter database open;
shutdown immediate;
startupSo, after this step, the database was a stand alone database, which doesn't have any standby databases yet (but it still has log_archive_config parameter set and log_archive_dest_n parameters set but i have 'DEFER' the log_archive_dest_n pointing to the old primary). I have even changed the "archive log deletion policy to NONE"
RMAN> configure archivelog deletion policy to none;After the fail-over was completed, the log sequence started from Sequence 1. We cleared the FRA to make space for the new archive logs and started off a FULL database backup (backup incremental level 0 database plus archivelog delete input). The backup succeded but we got these alerts in the backup log that RMAN cannot delete the archivelogs.
RMAN-08137: WARNING: archive log not deleted as it is still neededMy question here is
1) Even though i have disabled the log_archive_dest_n parameters, why is RMAN not able to delete the archivelogs after backup when there is no standby database for this failed-over database?
2) Are all the old backups marked unusable after a fail-over is performed?
FYI... flashback database was not used in this case as it did not server our purpose.
Any information or documentation links would be greatly appreciated.
Thanks,
Harris.

Thanks for the reply.
The FINISH FORCE works in some cases but if there is an archive gap (though it didn't report in our case), it might not work some times (DOCID: 846087.1). So, we followed the Switch-over & Fail-Over best practices where it mentioned about this "ACTIVE PHYSICAL STANDBY" for a fail-over if you intend not to apply any archivelogs. The process we followed is the Right one.
Anyhow, we got the issue resolved. Below is the resolution path.
1) Even though if you DEFER the LOG_ARCHIVE_DEST_STATE_N parameter's on the primary, there are some situations where the Primary database in a dataguard configuration where it will not delete the archive logs due to some SCN issues. This issue may or may not arise in all fail-over scenarios. If it does, then do the following checks
Follow DOCID: 803635.1, which talks about a PLSQL procedure to check for problematic SCN's in a dataguard configuration even though the physical standby databases are no available (i.e., if the dataguard parameters are set, log_archive_config, log_archive_dest_n='SERVICE=..." still set and even though corresponding LOG_ARCHIVE_DEST_STATE_N parameters are DEFERRED).
If this procedure returns any rows, then the primary database is not able to delete the archivelogs because it is still thinking there is a standby database and trying to save the archive logs because of the SCN conflict.
So, the best thing to do is, remove the DG related parameters from the spfile (log_archive_config, log_archive_dest_n parameters).
After i made these changes, i ran a test backup using "backup archivelog all delete input", the archive logs got deleted after backup without any issues.
Thanks,
Harris.

Bea weblogic 6.1 does not oracle Database fail over

Hi We had Concurrency Strategy:excusive . Now we change that to Database for performace
reasons. Since we change that now when we do oracle database fail over weblogic
6.1 does not detect database fail over and it need restart.
how we can resolve this ??

How do the application servers connect the new database after failing over from primary DB to standby DB

How do the application servers connect the new database after failing over from primary DB to standby DB?
We have setup a DR environment with a standalone Primary server and a standalone Physical Standby server on RHEL Linux 6.4. Now our application team would like to know:
When the primary DB server is crashed, the standy DB server will takeover the role of primary DB through the DataGuard fast failover. As the applications are connected by the primary DB IP before,currently the physical DB is used as a different IP or listener. If this is happened, they need to stop their application servers and re-configure their connection so the they coonect the new DB server, they cannot tolerate these workaround.
Whether does oracle have the better solution for this so that the application can automatically know the role's transition and change to the new IP without re-confige any connection and shutdown their application?
Oracle support provides us the answer as following:
==================================================================
Applications connected to a primary database can transparently failover to the new primary database upon an Oracle Data Guard role transition. Integration with Fast Application Notification (FAN) provides fast failover for integrated clients.
After a failover, the broker publishes Fast Application Notification (FAN) events. These FAN events can be used in the following ways:
Applications can use FAN without programmatic changes if they use one of these Oracle integrated database clients: Oracle Database JDBC, Oracle Database Oracle Call Interface (OCI), and Oracle Data Provider for .NET ( ODP.NET). These clients can be configured for Fast Connection Failover (FCF) to automatically connect to a new primary database after a failover.
JAVA applications can use FAN programmatically by using the JDBC FAN application programming interface to subscribe to FAN events and to execute event handling actions upon the receipt of an event.
FAN server-side callouts can be configured on the database tier.
FAN events are published using Oracle Notification Services (ONS) and Oracle Streams Advanced Queuing (AQ).
=======================================================================================
Who has the experience and the related documentation or other solutions? we don't have the concept of about FAN.
Thank very much in advance.

Hi mesbeg,
Thanks alot.
For example, there is an application JBOSS server connecting the DB, we just added another datasource and put the standby IP into the configuration file except adding a service on DB side like this following:
        <subsystem xmlns="urn:jboss:domain:datasources:1.0">
        <datasources>
                <datasource jta="false" jndi-name="java:/jdbc/idserverDatasource" pool-name="IDServerDataSource" enabled="true" use-java-context="true">

                </drivers>
            </datasources>

If the failover is occurred, the JBOSS will automatically be pointed to the standby DB. Additional actions are not needed.

Interactive report performance problem over database link - Oracle Gateway

Hello all;
This is regarding a thread Interactive report performance problem over database link that was posted by Samo.
The issue that I am facing is when I use Oracle function like (apex_item.check_box) the query slow down by 45 seconds.
query like this: (due to sensitivity issue, I can not disclose real table name)
SELECT apex_item.checkbox(1,b.col3)
, a.col1
, a.col2
FROM table_one a
, table_two b
WHERE a.col3 = 12345
AND a.col4 = 100
AND b.col5 = a.col5
table_one and table_two are remote tables (non-oracle) which are connected using Oracle Gateway.
Now if I run above queries without apex_item.checkbox function the query return or response is less than a second but if I have apex_item.checkbox then the query run more than 30 seconds. I have resolved the issues by creating a collection but it’s not a good practice.
I would like to get ideas from people how to resolve or speed-up the query?
Any idea how to use sub-factoring for the above scenario? Or others method (creating view or materialized view are not an option).
Thank you.
Shaun S.

Hi Shaun
Okay, I have a million questions (could you tell me if both tables are from the same remote source, it looks like they're possibly not?), but let's just try some things first.
By now you should understand the idea of what I termed 'sub-factoring' in a previous post. This is to do with using the WITH blah AS (SELECT... syntax. Now in most circumstances this 'materialises' the results of the inner select statement. This means that we 'get' the results then do something with them afterwards. It's a handy trick when dealing with remote sites as sometimes you want the remote database to do the work. The reason that I ask you to use the MATERIALIZE hint for testing is just to force this, in 99.99% of cases this can be removed later. Using the WITH statement is also handled differently to inline view like SELECT * FROM (SELECT... but the same result can be mimicked with a NO_MERGE hint.
Looking at your case I would be interested to see what the explain plan and results would be for something like the following two statements (sorry - you're going have to check them, it's late!)
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two),
sourceqry AS
(SELECT b.col3 x
       , a.col1 y
       , a.col2 z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5)
SELECT apex_item.checkbox(1,x), y , z
FROM sourceqry
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two)
SELECT apex_item.checkbox(1,x), y , z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5If the remote tables are at the same site, then you should have the same results. If they aren't you should get the same results but different to the original query.
We aren't being told the real cardinality of the inners select here so the explain plan is distorted (this is normal for queries on remote and especially non-oracle sites). This hinders tuning normally but I don't think this is your problem at all. How many distinct values do you normally get of the column aliased 'x' and how many rows are normally returned in total? Also how are you testing response times, in APEX, SQL Developer, Toad SQLplus etc?
Sorry for all the questions but it helps to answer the question, if I can.
Cheers
Ben

Failing over Oracle connections in a pool

          Hi,
          This message is probably a bit out of context (I've already posted
          it to the JDBC group). I post here as well, since I guess it's
          the place where people have the most experience with clustering
          and HA. Original posting below...
          Could you please tell me whether, yes or no, connections to an
          Oracle database should fail over (when the database fails over
          to another machine)? I use Oracle's Transparent Application Failover
          (configured via Net8) with Weblogic 6 on Linux and Oracle 8.1.7
          on Solaris/SPARC.
          If this doesn't work in my configuration, is there any configuration
          where it should work? (Another version of Oracle, WLS, OS, ...)
          When I try TAF using the PetStore application, I get exceptions
          related to no being connected to the database.
          If TAF doesn't work with WebLogic, is there a way to work around
          the problem? Can I catch these exceptions and renew the connections
          in the pool? Or, what else is possible...?
          I'd appreciate any help. I'd like to demonstrate our HA product
          with WLS. If it doesn't work, I'll turn to iPlanet instead. Pity,
          I really like WLS!
          Thanks in advance for any help or advice!
          Regards, Frank Olsen


          Hi (Frank ;-)
          I got carried away a bit too fast...
          Some more testing shows that it doesn't work in all cases:
          - when someone is trying to check out the shopping cart when the
          the database fails (and fails over), I get exceptions once the
          databses has restarted on the backup node
          - the exceptions are related to some transactions being rolled
          back and Oracle stating that it couldn't safely replay the transactions
          - browsing the categories still works fine
          - all access to the shopping cart and sign-in/sign-out causes time-outs
          and exceptions
          Any ideas what may cause this problem, please?

          Frank Olsen

Rapidwiz fails on database step for 12.1.1 on Oracle Linux 5.7

I am trying to install Oracle EBS 12.1.1 on Oracle Linux 5.7 64 bit platform.
The issue is that after I followed the requirements including set kernel parameters by using the oracle-validated RPM package, the install fails on database creation step.
Below are logs:
getConnectionUsingSID() -->
JDBC URL: jdbc:oracle:thin:@ebsdb01:1526:VIS
Exception occurred: java.sql.SQLException: Io exception: The Network Adapter could not establish the connection

Any ideas how to solve this issue? I even used latest release of Rapid Install wizard and no luck.

RDA is a diagnostic script for looking at requirements and settings from MOS.
I run this way:
perl rda.pl -T hcve
with results:

If you are running the one in (RDA 4 - Health Check / Validation Engine Guide [ID 250262.1]), then I believe it is only available for "Linux-x86 Platforms" (32-bit).
2) I notice issue with DNS configuration:
[root@ebsdb01 rda]# nslookup 122.2.2.2
Server: 122.2.2.2
Address: 122.2.2.22#5
** server can't find .in-addr.arpa.: NXDOMAINThis is a network issue, please check with your network admins/team.
3)
So this leads me to my next question, when I use nslookup to search the domain on the DNS server for the host, it resolves successfully. BUT, when I run nslookup against the IP address
it cannot find it in DNS. Would this be the root cause of why my installation keeps failing? I have verified checksums and software is fine. I am still missing a couple RPMs but do not believe this is what causing the install to fail yet in light of the network connection errors that Rapidwiz keeps throwing at me.All network files/settings can be found in (Oracle E-Business Suite Installation and Upgrade Notes Release 12 (12.1.1) for Linux x86-64 [ID 761566.1]).
Thanks,

Problems with Oracle FailSafe - Primary node not failing over the DB to the

I am using 11.1.0.7 on Windows 64 bit OS, two nodes clustered at OS level. The Cluster is working fine at Windows level and the shared drive fails over. However, the database does not failover when the primary node is shutdown or restarted.
The Oracle software is on local drive on each box. The Oracle DB files and Logs are on shared drive.

Is the database listed in your cluster group that you are failing over?

Connect to database failed,rc=-10709 Connection failed (RTE:Database name)

Hi gurues, I'm facing this issue with an IDES on MaxDB with Windows.
System was up and running until someone tries to make an upgrade of the kernel. Since then we can not start our system. we tried to rollback kernel release to the previous one but it didn't work.
When we start our system from MMC console we can see all process in green but work processes are in RUN state and after a few minutes they goes down with the following error
trc file: "dev_w0", trc level: 1, release: "701"

Database Service Name or Global Database Name with Oracle 10G, when Oracle

I have an old installation of Oracle 9i (SID=ORCL) and now have installed Oracle 10G (SID=ORC2). I can get connection to Oracle 10G if i define it as an Oracle 8 compatible identification (ie I access to a SID, and donÂ´t provide a Service Name.
Now I want to install Oracle HTML DB, and succeeded to install the SQL-script that came with the download, but when I install Apache and HTML DB from the Oracle Companion CD I am asked to give the Database Service Name (in the Help it is explained as the Global Database Name).
When i give the Net Service Name I get error messages (incomprehensible).
When I look in Net Manager, the Net Service Name does not have a Service Name, but only points to a SID (ie ORC2).
Where can I find the Database Service Name (or Global Database Name), OR define it if it is not defined??
Thanks for your help,

create a net service for oracle10g and provide the name of this service during HTML DB installation it is required for installation.

Multiple types of database and fail over clustering

Hi,
I have a few questions here.
1) Can I have 2 types of databases (eg: OLTP and OLAP)run at the same time on a same machine?
2) Can I implement a cross fail over cluster in this situation? Meaning I have 2 machines with OLAP and OLTP database instances installed in them (replica of each other), 1st machine running OLTP and 2nd running OLAP. In the situation where one of machines fail, the passive instance on the other machine takes over (back to situation on question 1).
Thanks

Primary Mailbox Database fails to replicate after failing over to secondary copy in DAG

We had an issue yesterday on a primary mailbox database server when the drive the log files are located on filled up and took the databases off-line on the primary server bringing them up on the secondary.
After the issue was resolved and enough space was freed up, all but one database failed back. The one that would not come back showed Failed in the copy status. It remained mounted on the secondary server. I attempted several times to 'update' the copy and
it would run for aver 40 minutes and look like it was going okay then it would 'fail' and end up in a 'failed and suspended' state. The error would indicated it could not complete because the it could not find the source server.
The Update job was configured to point to the server holding the secondary copy as the source so should not have a problem.
Any idea on how I can get the primary copy working again? I thought about making the second copy the 1st to activate and removing the primary copy from the DAG and recreating it, but past experience doing that did not resolve the issue.
Thank you,
Nick
