Distributed Transaction - Ensure Commit
Jun 26, 2013Query in format Query@DB_Link is sometimes dropping transactions. Move it to a package on target dababase "B" called from DATABASE "A" via package.procedure(varaibles);
Is that all I need to do to get the transaction to always go? I tried a commit in the package body, with repeated attempts if it fails. Btu when I use commit, the package doesn't work. (Compiles fine) Why would the commit fail?
My goal is to make that the transaction succeeds.Code for what I tried below. the COMMIT is commented out - if I uncomment it, the transaction fails. I have done this before calling an oracle SP from SQLServer and it worked
Comments:
The loop is to avoid an endless cycle..The concept is to perform the update, commit it, if the commit fails, rollback and try again.I'm not sure if I even need a loop, but I don't know if the unresolved transaction would get fixed by the remote DB, or dropped.

View 10 Replies View RelatedServer Administration :: Can Oracle Always Guarantee Data Consistent In Distributed Transaction
Mar 31, 2013I have read almost all docs about distributed transaction on tahihi.oracle.com website,But I can find a statment about this:
Can Oracle always guarrantee the data consistent in a distributed transaction?
For example,there is a distributed transaction on node a,node b and nod c.node b and node c informed node a they were prepared,so node a committed,and inform node b and node c commit.then node b committed and feedback,but network on node c broken at this point,So node a can't not get feedback from node c,but node a and node b has been committed, so what will Oracle do in this condition?
If node c rollback the data on local node, consistent in this distributed transaction was failed ,yes?
SMTP Transient Error - 452 4.3.1 Insufficient System Resources
Nov 13, 2012We're using UTL_SMTP to send emails from Oracle, and about 2 weeks ago (2 days prior to daylight savings) we start seeing an intermittent "SMTP transient error: 452 4.3.1 Insufficient system resources".
When there's an issue, emails fail from all 3 of our database environments (on separate servers), which leads me to believe that it isn't Oracle's error. But, our Exchange server isn't showing anything in it's Application Event Log, nor it's Protocol Log (although we just changed settings to log more information).
I'm just trying to rule out Oracle at this point, so we can focus our efforts. I've been looking on Google for the past hour and a half, and I can't find anything which points to anything other than the mail server being the culprit in an error situation like this. But, how to determine if the database should stay on the list of items to look into.
Real Application Clusters :: Quickly Relocate Resources To Available Node?
Sep 21, 2012version : 11.2.0.2 on RHEL 5.4
In our 2-node RAC , Node1 was hung for a while. So, I wanted to restart that Instance. But I had some 50 services running in Instance 1(Preferred Instance) which has to relocated before I bounce the instance.
Question 1.
Instead of using srvctl relocate for each service, Is there any way to quickly relocate all services to the Node2 (Available Instance) ?
Question2.
When a service is relocated , are DMLs running from sessions using that service be 'moved' to the available instance ? Or, is it just the SELECTs that can be failed over ?
RAC & Failsafe :: Creating Cluster Resources For Oracle Enterprise Manager Using Clusterware
Oct 24, 2012My application consists of Oracle RAC and Oracle Enterprise Manage (OEM) on same two nodes. I am exploring the idea of utilizing Oracle Clusterware (which is already installed with Oracle RAC) to support OEM in active passive mode.
Here is the scenario.
Node A running Solaris 10.9 on SPARC and Node B running Solaris 10.9 on SPARC.
Node A and Node B are both Oracle RAC Nodes ( Active Active ) which use Shared Storage for Oracle using ASM.
Node A and Node B will run Oracle Enterprise Manager (OEM) Application in active passive scenario which will be using Oracle RAC for its database. So, both Oracle RAC and OEM are sharing same server A and B for its clusters.
Now, OEM application need a third party clusterware to fail it over. It needs clusterware to provide floating VIP and shared folder of the size of 20GB which will keep software libraries. If node A goes down, node B have access to same libraries and will come up as active.
Do you know if oracle clusterware which comes with Oracle RAC can support OEM for failing over i.e. it can provide floating VIP and shared file system?
Intermediate State / Check Cluster Resources By Srvctl Status Resource
Oct 17, 2013We are in 11gR2 in windows 2008. Our database is 2 nodes rac. I got alert message below.

I did check the cluster resources by srvctl status resource -t and all of resources are in online and none of them i saw in intermediate state. Is there any other command and option to investigate this error?
Distributed Operation Not Supported
Jun 12, 2013I am using the dblink to merge the data. I am using the following merge statement.
merge into APP_USER.USR_NEW_RIGHTS@NEW_RIGHTS t
Using (select 'test' GRANTEE,'TESTxxx'ROLE from dual ) s
on (t.GRANTEE = s.GRANTEE and t.ROLE = s.ROLE)
when not matched then
insert (ID,GRANTEE,ROLE,XRIGHT,COMPANY,OWNER,TABLENAME)
values ('','test','TESTxxx',null, null, null, null);
I know that I have to set a commit and it's working when I insert information's with a normal insert statement via database link, but it seems that merging doesn't work.

SQL & PL/SQL :: ORA-02064 - Distributed Operation Not Supported?
Apr 20, 2011When I try to call a database procedure written in Oracle 8.1.7.4.0 with OUT parameter and COMMIT statement from my Oracle 10g environment, I am getting error like "ORA-02064: distributed operation not supported".
I cannot omit OUT/COMMIT statement from the procedure because it is also updating another table from called procedure. I have tried some solutions from my end, but it is not working and same error generating. Like:
1) Moved the update statement with COMMIT statement to another procedure and calling that procedure from main called procedure
2) Creating a job to run the newly created procedure and submit the job from called procedureetc.

Queueing :: How To Configure Oracle AQ For Distributed Environment
Sep 23, 2013I have a scenario In which I have say 4 AQ in which I will post the message.Also i have say 2 database.I am planning to create an MDB which will poll on these AQ's, so whenever I post message the MDB will read it and perform a specific action.I believe I can create only one MDB per queue, if it is so then I have to create 8 MDB.
As there 2 datasource and 4 MDB. Is there any other way to handle this I mean without creating 8 MDB as the Data sources can increase to 10 to 20 so the number of MDB will be 20 to 40.I guess this will affect the application performance. Can I make some changes in application so that only few MDB's are required?

Performance Tuning :: NESTED LOOPS JOIN And Distributed Operations?
Oct 30, 2012 I want to make sure I am describing correctly what happens in a query where there is distributed database access and it is participating in a NESTED LOOPS JOIN. Below is an example query, the query plan output, and the remote SQL information for such a case. Of particular note are line#4 (NESTED LOOPS) and line#11 (REMOTE TABLE_0002).
What I want to know is more detail on how this NESTED LOOPS JOIN handles the remote operation. For example, for each row that comes out of line#5 and is thus going into the NESTED LOOPS JOIN operation @line#4, does the database jump across the network to do the remote loopkup? Thus if there are 1 million rows, does that mean 1 million network hops? Does batchsize play a role? For example, if the database batches in groups of 100 then does that mean 10 thousand network hops?
I think each row that comes out of line#5 means a network hop to the remote database. But I do not know for a fact.I have done some abbreviating in the plan in an attempt to make it fit on the page (line#7 TA = TABLE ACCESS).

View 0 Replies View RelatedObject Locked But Can't Find Session / Process Blocking?
Sep 5, 2012I am on database 10.2.0.5, windows x64.
A developer calls me and tells me there are locks on 3 tables, and the locks are not released. So I run this to see which objects are locked by which session
select vlo.object_id, vlo.session_id, vlo.oracle_username, vlo.process
, DECODE(vlo.LOCKED_MODE, 0,'NONE', 1,'NULL', 2,'ROW SHARE', 3,'ROW EXCLUSIVE', 4,'SHARE', 5,'SHARE ROW EXCLUSIVE', 6,'EXCLUSIVE', NULL) LOCK_MODE
, do.owner, do.object_name, do.object_type
[code]...
When I run the query later, I sometimes get another session, but the lock stays. It seems here, that I am catching the same SID on new sessions, but it is probably a different serial # than the original session locking the table rows.
I get nothing from
select * from dba_waiters;
select * from dba_blockers;
Now why are those 3 tables row locked on some rows and I can't find the session responsible? The developer tells me his application crashed and the rows are locked since. So far ( keep in mind I am not a locking expert) the only way I found to release the locks is a DB bounce, its a test DB so no biggy.
