Replication :: Possible To Make Service Running Even When Node Falls?
Sep 23, 2008
I've configured a replication environment with Oracle 11g (Multi-master synchronous replication). Apparently it works fine, when replication is started any change in a table that belongs in a node is replicated in the rest of the nodes.
One of the tests I'm making is the following: Try to see what happens if one of the nodes drops. Meanwhile one of the nodes is no avalaible, any modification in an available node is not allowed (as I expected). I'm trying to see if the database service can be available meanwhile a node is missing, although the replications is not running.
What I've experienced is replication cannot be suspended until the the node was down is restarted.
Is this the usual behaviour or can I set any parameters to avoid this? In other words, is it possible the database service is running meanwhile one of the nodes is down? The application I'm working on needs this type of replication, buy also needs the service is running always?
What can I do to make possible the service is running even when a node falls?
We have an Oracle 9i (9.2.0.7) two-node RAC database running on Solaris 5.8. Recently we have switched our production database from no archive log mode to archive log. We changed the parameter CLUSTER_DATABASE=FALSE on one of the instances before converting and reverted back.why this parameter needs to be changed to false?
I have 2 node 11gR2 RAC running on AIX 6.1, after I shutdown the database and restart crs using crsctl start crs, ASM instance comes back up but not the database and I had to start the database using srvctl, isn't that the database should come up when I start the crs?
during installtion of Oracle RAC 11g r1 on Linux using VMware server, all the pre cluster installation was successful, and 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 the Oracle 11g XE database installed on a Windows 7 laptop. The Oracle XE database runs fine when the laptop not connected to a network, when connected to our corporate lan, or when connected to a cable-modem. However, when running under the Cisco AnyConnect VPN client, we are unable to connect to the Oracle XE service.
I have tried to resolve this, but am stuck. I do not if this issues is caused by: 1. There is no IPv6 address listed for the AnyConnect VPN (from ipconfig /all)? 2. Something regarding split-tunnelling that must be configured on the VPN? 3. Can the Oracle XE database run under an SSL VPN?
Below is the output of when I try to connect the Oracle XE service via sqlplus. ************************** The OracleXETNSListener service is starting. The OracleXETNSListener service was started successfully.

How does an oracle materialized view log host keep track of pulling oracle materialized view clients?By global service name or databaseid?
Case: Oracle database host A hosting table X with corresponding materialized view log MLOG$_X Oracle database host B creates a materialized view on A.X using fast refresh (pull) Oracle database host C creates a materialized view on A.X using fast refresh (pull)
How does Oracle database host A keeps track of host B and C in order to clean up MLOG$_X?
We have 2 Sun Solaris (Solaris 10) nodes each has an oracle db, and OID of the above versions.There is an ASR running between both nodes, and it has been setup as follow:

Make sure that the replication administrator that you enter below does not exist already in any of the nodes that will be part of the DRG to be created now. If the user exists, that user will be dropped and will be created newly.

We ran a perl script which is using ldapmodify to change the value of one attribute in all records (7 Millions records).That has been done by creating many of LDIF files each of 10,000 records in 26.04, and by mistake this script has ran 3 times in parallel.Currently the replication between both nodes are stuck, and when I query the ods_chg_log on the master node (node1):
SQL> select count(*) from ods_chg_log;
COUNT(*) ---------- 6690594 And the number is not decreasing. And I queried on the asr_chg_log on the master node (node1): SQL> select count(*) from asr_chg_log; [code]....
Oracle VM 2 Node RAC cluster Oracle 11G 11.2.0.3.0 Oracle 11g rel 2 GI
on current 2 node cluster we have GI and RAC db configured Nodes: vmorarac1,vmorarac2
we shutdown vmorarac1 to clone it to vmorarac5
on new node I have changed the hostname to vmorarac5 In /etc/sysconfig/network-scripts/ifcfg-eth0 change ip to new ip and same for /etc/sysconfig/network-scripts/ifcfg-eth1 152.144.199.210,152.144.199.211
mad echanges to /etc/hosts on vmorarac1/2 for 2 new IP address assigned to vmorarac5
I believe, in a multiple RAC Physical Standby nodes only one node applies the archivelogs to the standby database. How you can find which node is the APPLY NODE using a SQL query?
I know you can veiw this information by querying the standby configuration using DGMGRL but how would you find out this information from a remote client using SQLPlus/PLSQL?
We have oracle database 10g(10.2.0.4) running on AIX 5.1. we have installed 2-node RAC on another server AIX 6.1 . Now we want to migrate our single node database to new 2-node rac environment. how we can move/migrate/cluster-aware our single node database to 2-node rac?
I am installing Oracle 10g Clusterware in RHEL 5 Server. When i run root.sh in the second node the last step Running vipca(silent) for configuring nodeapps failed. Then i run VIPCA manually in second node and configured vip configuration successfully,but when i checked the post-checks for cluster services the Checking existence of VIP node application,Checking existence of ONS node application and Checking existence of GSD node application in second node failed. I am able to ping both the servers one another with vip name successfully and the CSS,CRS and EVM appears healthy in both nodes. 1. Does the vip configuration is proper? If no what is causing this error and how to rectify it? Find the output below
I would like get more details about single node RAC.. What is single Node RAC?..
1). just configure only one server instead of two node... same RAC installation.. cluster installation and shared disk configuration in single server itself.. in future we can add node to this ... 2). in 11gR2 having new feature Single Node RAC.. Multiple instances running on same node and configure using Cluster...
is there any advantage using single node rac(other than online upgrade to full RAC).
I'm trying to add the third node to my existing two node cluster. In fact i succeded adding the node but i have the following problem:
-when i start node 1 and 2, everything is ok, but on node 3 startup one of the other nodes fails -this happens in any combination: start 1 and 3, everything is ok. when i start node 2, node 3 fails
The asm configuration (disks, permissions, etc) is the same on all three nodes.find below the asm and crsd log details from the failure time:

Actually am trying to replicate two db servers from one in hong kong and another in china. when am trying to establish the replication, am getting error 'ORA-04052: error occurred when looking up remote object' like this...
but the same way i have tried in my local network, it is working fine.i have tried schema replication through enterprise manager grid control..
i need to set up a central server with all the master tables and two other local database which will hold the updatable materialized view of the master table...the databases must be synchronized with central server..and user will work on the materialized view database...
I want to set up advance replication for 3 master site (multimaster) I created 3 master site named orc1,orc2,orc3 and followed up oracle replication management of API book instruction I created 2 tables(tes1,test2) in hr schema in all 3 master site with the same data. then I created the following steps
1-CONNECT repadmin/repadmin@orc1
2-Create the master group named hr_test_repg
BEGIN DBMS_REPCAT.CREATE_MASTER_REPGROUP( gname => 'hr_test_repg'); END; /
4-add tables test1 and test2 to the group
BEGIN DBMS_REPCAT.CREATE_MASTER_REPOBJECT( gname => 'hr_test_repg', type => 'TABLE', oname => 'test1',
[code]....
I could create DBMS_REPCAT.GENERATE_REPLICATION_SUPPORT for test2 but not for test1 and it produces error

I have one 10g database in other country. I want part of their db (selected tables or tablespaces) and import that data to my 10g DB and i want keep to date this data.
I know two ways
1. Data Pump Imp/Emp via FTP, but i can't send only data that have changed (incremental), i must pumping whole selected part of database (i want only new data from their DB, but consistanse with my DB)
2. RMAN etc. or other archivisation tool, i can do incremental achivisation, but can i send files to another instances (my db) and load only that data? Can i do that with SQL*Loader?
For using replication in our production, here i am testing golden gate as replication tool. I tested all scenario in Uni direction ( source to destination). Now have to test replication with DDL support in Bi-Direction. Not getting any Doc for doing replication in Bi-direction( Two Way). If any one has done the same, then please share limitation of replication in Bi-direction through Golden Gate.
I Have configured the replication between two database's at table level. After few miniuts of successful configuration of replication between two db's at table level, I am getting the ORA-00001: unique constraint (%s_PK) violated error in dba_apply_error.
I checked constraint name,type and status on table replicated is same on both source and destination db.
I am using prebuilt MV to perform replication of about 300-400 master tables from one database to another database. I am wondering about the impacts on triggers in general replication.
IS there a general rule to enable/disable a trigger before a refresh.
I want to configured A Synchronous replication in oracle 8i. Noe using GUI i am bale to create replication but whatever i modify it remain in the transaction i have to manually run the job ,
I also tried to configured continuous asynchronous configuration by setting delay rate 500000. but it was also not working.
Is it possible to replicate table data on real time from sql server (2005 32 bit or sql server 2000 32 bit)to oracle 10g running on linux 64 bit? If yes then what are the steps.
It will be one way replication from sql server to oracle. Which option is best sql server dts or Oracle Stream replication to replicate table data.
