Establishment of multimaster environment on 11g and replication
Hey guysI think I'm getting my guide install completely fake. We implement 4 multimaitres servers. Allows to call the A B C D. Also, each have say 4 created suffixes. Say S1 S2 S3 S4. Here are my questions.
The steps that I take are
(1) installation A and B
(2) created the suffix S1 S2 S3 S4 (empty on both servers)
(3) allowing the Master Replica (http://docs.oracle.com/cd/E19424-01/820-4809/bcaqf/index.html)
Now run us the server command has to B
the host $ dsconf enable-repl - port d ReplicaID Pei h master DN suffix
If the command is on a server? Also is the correct syntax?
$ dsconf enable-repl - h HOSTA Pei 1 389 master S1 S2 S3 S4
Then on server B
$ dsconf enable-repl - h HOSTB Pei 389 2 master S1 S2 S3 S4
(4) create replication agreement (http://docs.oracle.com/cd/E19424-01/820-4809/bcaqj/index.html)
The command is: $ dsconf create-repl-agmt - h consumer of suffix-ND - p port of the host-host: consumption-port [consumer-host: consumption-port]
So now the server has (will be this replication of configuration on both directions? IE A-> B and B <-A? or need additional commands?)
$ dsconf create-repl-agmt - h HOSTA Pei 389 S1 HOSTB:389
$ dsconf create-repl-agmt - h HOSTA Pei 389 S2 HOSTB:389
$ dsconf create-repl-agmt - h HOSTA Pei 389 S3 HOSTB:389
$ dsconf create-repl-agmt - h HOSTA Pei 389 S4 HOSTB:389
(5) to import data into the suffix (S1 S2 S3 S4) ONLY on the server a (Correct?) This will launch the replication on the server B.
========================================================
(6) install C and D
(2) created the suffix S1 S2 S3 S4 (empty on both servers)
(3) allowing the Master Replica (http://docs.oracle.com/cd/E19424-01/820-4809/bcaqf/index.html)
Command is on Server C
$ dsconf enable-repl - h HOSTC Pei 389 3 master S1 S2 S3 S4
Then on the server!
$ enable-repl - h dsconf PASS Pei 389 4 master S1 S2 S3 S4
(4) create replication agreement (http://docs.oracle.com/cd/E19424-01/820-4809/bcaqj/index.html)
If the C Server (or on a server?)
$ dsconf create-repl-agmt - h HOSTC Pei 389 S1 HOSTA: 389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S2 HOSTA: 389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S3 HOSTA: 389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S4 HOSTA: 389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S1 HOSTB:389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S2 HOSTB:389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S3 HOSTB:389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S4 HOSTB:389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S1 HOSTD:389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S2 HOSTD:389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S3 HOSTD:389
$ dsconf create-repl-agmt - h HOSTC Pei 389 S4 HOSTD:389
Then on the server!
$ dsconf create-repl-agmt - h SPEND Pei 389 S1 HOSTA: 389
$ dsconf create-repl-agmt - h SPEND Pei 389 S2 HOSTA: 389
$ dsconf create-repl-agmt - h SPEND Pei 389 S3 HOSTA: 389
$ dsconf create-repl-agmt - h SPEND Pei 389 S4 HOSTA: 389
$ dsconf create-repl-agmt - h SPEND Pei 389 S1 HOSTB:389
$ dsconf create-repl-agmt - h SPEND Pei 389 S2 HOSTB:389
$ dsconf create-repl-agmt - h SPEND Pei 389 S3 HOSTB:389
$ dsconf create-repl-agmt - h SPEND Pei 389 S4 HOSTB:389
(5) replication should kickoff importing data in C and D of A and B
=========================================================
Please guide me where it is an error and the correct procedure to install 4 servers multimater and replication configuration between them
The command is: $ dsconf create-repl-agmt - h consumer of suffix-ND - p port of the host-host: consumption-port [consumer-host: consumption-port]
So now the server has (will be this replication of configuration on both directions? IE A-> B & B)<-A? or="" need="" additional="">-A?>
"create-repl-agmt dsconf" creates only a unidirectional replication agreement. In ODSEE there is no such thing as a two-way replication agreement. You must define how changes should circulate and create a new agreement for each link. So in your case, if you would like the changes made on B to A, then create another series of agreements from B to A.
(5) to import data into the suffix (S1 S2 S3 S4) ONLY on the server a (Correct?) This will launch the replication on the server B.
N ° import does not disable replication, only the updates. If the suffix S1 on B is empty, then you init it before it can receive updates a. Your choices are
1 Init has. Then online at init from A to B (dsconf init-repl-dest)
2 Init A. A export (dsconf Pei 389 S1 to export), copy the LDIF to B and init (dsadm import)
It might be easier to see option 2. So:
-Initialize all suffixes on A
-Export all suffixes of four. This will ensure that all instances will get the same copy of entries (including all replication metadata)
-Copy the files LDIF for B, C and D
-' Import dsadm' run in parallel.
-create the repl agmt as you want (a one-way ticket)
-make a change on one and watch it appear on the other three.

I have two databases 11g and 10g on a single server.
11g uses a port 1522 10 g using port 1521.
At the start of the 11 g database I get the following error:
SQL > bootable media.
ORA-00119: invalid specification for the system LOCAL_LISTENER parameter
ORA-00132: error syntax or network name not resolved "LISTENER_DB11G."
Can I copy my 10g listerner.ora enty in my listnerer.ora 11g and rename/edit the 10g to listener2.
and start then 11g receiver?
I prefer to use the two auditors.
Thank you...user8969 wrote:

That what I have to do to get the two DB on the same listener was my question.I received this Burleson Oracle DBA Forum:
http://dbaforums.org/Oracle/index.php?showtopic=9569Thank you.
There is room for improvement in this other thread. Some examples of file listener.ora to a 10g R2 on Windows listener serving 10.2.0.4 11.1.0.7 database instances:
TRACE_LEVEL_LISTENER = 0 SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = VM) (ORACLE_HOME = C:\oracle\product\10.2.0) (SID_NAME = VM) ) (SID_DESC = (GLOBAL_DBNAME = LT) (ORACLE_HOME = C:\oracle\product\10.2.0) (SID_NAME = LT) ) (SID_DESC = (GLOBAL_DBNAME = LT2) (ORACLE_HOME = C:\oracle\product\10.2.0) (SID_NAME = LT2) ) (SID_DESC = (GLOBAL_DBNAME = VM11) (ORACLE_HOME = C:\Oracle\Product\11.1.0) (SID_NAME = VM11) ) (SID_DESC = (GLOBAL_DBNAME = VMTEST) (ORACLE_HOME = C:\Oracle\Product\11.1.0) (SID_NAME = VMTEST) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.185.50.51)(PORT = 1521)) ) ) SAVE_CONFIG_ON_STOP_LISTENER = TRUE
There are probably things to improve in the above listener.ora file, but it works. It is also possible to use a 11.1.0.7 earpiece to maintain a 10.2.0.4 database instance - the listener.ora follows the same pattern.

Problems opening existing Oracle 9i in the new environment of 11g
Hello world
I have a challenge for you! Just to be clear, I am not a specialist of the Oracle (or call me a noob Oracle).
Challenge: Open an Oracle 9i database in a new Oracle 11 g environment.
Result: Be able to connect to an Oracle database running with "SSMA for Oracle" to convert it to a SQL database.
Starting point:
-Receipt of the customer: DBF, CTL and logs of an Oracle environment existing.
-Since I can't download Oracle 9i environment, I chose to install 11g environment and hope for a good backward compatibility.
How I got:
-Installed 11g environment
-Set up a database pointing to the files DBF
~ Change init.ora to use CTL files
~ Create init.ora spfile
~ Start database mount and rename the database and data files using sqlplus (liaison with "sys as sysdba")
Questions:
Now I can start the database, but sometimes with a * "ORA-00704: bootstrap process failure" * and recommend I start it with the UPGRADE option. "» Start with UPGRADE option works and I can navigate through the database using Toad tool (login 'as sysdba'). But 'SSMA for Oracle' is not an option to connect 'as sysdba' and gives me a "ORA-39710: only connect AS SYSDBA is allowed when it is OPENED in UPGRADE mode.
Since the MASA for customer Oracle cannot connect to a database started with the UPGRADE option I probably have to fix the "ORA-00704: bootstrap process failure»
I tried to avoid the upgrade option in trying to upgrade the database to 11g. But utlu112i.sql and catalog.sql give me errors like "ORA-04023: object SYS." STANDARD cannot be validated. "
Issues related to the:
-Do you think I want to achieve is possible at all?
-Can I easily run an Oracle 9i database in a 11g environment or what I really need to upgrade?
-Do you think it is the best way to get an Oracle existing database running in a new environment?
-If Yes: how to solve the error ORA-00704?
If you need more information, alert logs, files .ora or anything to give an appropriate response, please ask and I'll give them.
Thanks in advance!
Kind regards
DirCoHello
9i binaries are no more on the website of oracle since this version is located in the long ago.
What I would do (since you have your files backed up somewhere, at least I hope) is simply:
Set oracle_sid = xxx
sqlplus/nolog
Connect / as sysdba
start upgrade
@?\rdbms\admin\catupgrd.sql (to upgrade the database)
@?\rdbms\admin\utlrp.sql (to compile the modules)Wait a while (2-3 hours)
immediate stop
startupCheck no errors in alert_log and you have access to your data.
Then 2 possibilities:
It worked - so everything goes well for you.
It does not, replace your original files and try something else.I think this will work if, as we have already said, you're 9.2.0.4 or more.
Do not lose time on futile questions such as 'what is really the version of my files. You care, upgrade script works for all of the above versions 9.2.0.4.
Don't forget that:
Passwords are now (11g) case sensitive (but you can change them when logged in sysdba)
Some pl/sql will not compile, but I think that you are mainly interested in the data.I hope this helps.

File sharing and replication, some questions
Hi guys.
First of all, my sistem
A vsphere cluster 5.1, with 7 guest esxi with a shared storage (HDS).
So I have a few machines virtual replication to an external site, with a cluster of vsphere 5.1 with 3 esxi host. But a bad broadband bandwidth beetween the two sites.
There is one machine virtual replication with several activities of memory, and I will not reproduce his memory.
I read this article and says that isolated swap file in a different data store and not replicate this data store.
http://www.VMware.com/files/PDF/Techpaper/srm5-perf.PDF
(see fig 19).
but I have a few questions:
-Store data file must be shared or a different data store peer esxi host?
-Vmotion host is not affected?
-Same datastore must exist in both groups?
-Impact on other virtual machines?
Thank you
Hello
Under normal circumstances, you should store the swap files in the same data store than the other files of the virtual machine. However, you need to prevent replication of swap files to avoid excessive consumption of band network bandwidth. In addition, certain providers of storage is recommended that you do not replicate files to Exchange. Only to prevent the replication of swap files if it is absolutely necessary.
If you use a replicated data store to Exchange files, you must create a data store replicated for all recovery sites and clusters protected both the protégé. The replicated data store should be visible to all the hosts in the cluster, or vMotion will not work.
It does not affect the other VM.

vSphere PowerCLI and replication
Hello
I ve seen a discussion about this in the forum, though none recently.
Would it not possible to trigger a failover of PowerCLI?
My thought is to trigger a script of our UPS in case PowerFailure to stop a virtual machine and it lights on another host in another location. I have only a virtual Center and the two hosts attached to it.
The script should do the following.
- Stop the machine source
- Activate failover
- Turn on the destination on the new host machine.
Would this be possible?
Hello
The original question was about turn on/off the VM another host on a different location. I guess that there is no storage shared between the two locations. vSphere replication could be used to replicate the VMDK, but yes, there is currently no Automation (unless using the API of SRM and SRM currently requires two vCenter servers - each manage its location).
Kind regards
Martin
