How Many Databases Were Installed In A Given Server / Machine
Apr 10, 2013
10g and 11g
SLES 10
My boss has assigned me a task to check/audit a existing PROD + other databases which was configured (in a server or servers) by previous dba who have left with no documentation.I am just given the server ip and root password.
-How do you attack this kind of task?
-How do you know how many databases were installed in a given server/machine?
-How do you get all the oracle_home being defined or used?
Is /etc/oratab enough to start with?Is oraInventory enough to know all the databases installed? Is this keyword unique, and kind be search using "find / -name "oraInventory"?Do I need to find the existent of the "oracle" exec in all "bin" since this is the unique identifier of an OracleHome?

I need to figure out which Oracle Database packages are installed on a certain server.
First problem: no Enterprise Manager available. So I need some command line tools or SQL statements.
I've already found some with them I was able to spot RAC, partitioning and so on. But I'm still missing a option/command to spot
- diagnistic pack
- tuning pack
- web logic
- web server

We are using Oracle Applications hosed on UNIX servers. There is a custom form in XXX_TOP/forms/US folder that I need to modify.
My Windows desktop has Forms Builder 10g installed. I ft pied fmb file over from UNIX server to my Windows desktop and tried opening it. I get an error FRM-18108:
Failed to load the following objects: APPSTAND, etc etc.
Obviously I am not doing it right. What is the correct way of modifying a form file sitting on UNIX server, using Forms Builder installed on Windows desktop? Do I need to copy all dependent objects to Windows desktop along with fmb file?

working on setting up connection between a Windows 2008 server and a pair of Oracle 11g DBs in a RAC Cluster. One Database (let's say DatabaseA) is in one data center, and the other (DatabaseB) is an a secondary, backup database. The RAC Cluster is all set up, working fine, etc. However, I Need to set up the machine.config file on my Windows Server, to go only connect to DatabaseA, unless it fails, in which case, we want it to connect to DatabaseB. Think we could do this if the host app server was Linux/Unix, but it is windows, and I just don't have the background as to the parameters to set up in the machine.config file. They are similar, but different, and we want a very specific behavior (use DatabaseA, unless fails, then DatabaseB). Application is .NET 4.0 app.

I have installed oracle 11g Release 11.1.0.1 on windows server 2008.I access this server from a client machine running on winXP through SQL PLUS. I wanted to shutdown and start DB server from this client machine. Accordingly i issued shutdown immediate command from SQLPLUS.
Now when i tried to start the DB with "STARTUP NOMOUNT" command i received error 12514. I understand this error means that the listener received a request to establish connections to a database but since DB services are not up and running, hence the error. So my first question is how do I resolve this error.
Continuing further, i tried to re-connect to the database as sys, and i received another error ORA-01041. So, my second question is why did i receive this error and again how can i resolve it
may be you can point me to relevant reference in Oracle documentation) how can i start and stop oracle from a client machine using SQL interface in CLI mode and windows environment and avoid this error.

I have a requirement to move the databases to a new server.
Existing set up:
database1-40GB,
database2-40GB,
database3-180GB
Oracle version - 11.2.0.2
OS - UNIX AIX-5.3
New Server (setup):
database1-40GB,
database2-40GB,
database3-180GB
Oracle version - 11.2.0.3
OS - UNIX AIX-6.1
My query is what is the best way to move the database to new server(UNIX AIX 6.1)?
a) can i upgrade the database to 11.2.0.3 before moving to new server or its better to move the database in 11.2.0.2 and then upgrade there?
b)is export and import of database can work for moving this?
c) RMAN backup and restoration can be done for moving databases?
d)simply moving all the related files to new server and start upgrading it from there?

Using suppress triggers options in golden gate. I was trying to work on the same but it doesn't seem to work at least for me.
Scenario:
Database Version 11.2.0.2
GoldenGate v11
OS Windows
Created two databases on the same server with same schmea idea was to replicate change from one database to other. One of the tables in the source database had trigger(every insertion in the table would cause a row to be inserted into a diff table). if row was inserted in table A it will insert a new row in table B . the same records will pass on target but the trigger defined on table A should not trigger on target as it has already fired on Source .
I tried using suppresstriggers but it doesnt seem to work everytime the trigger is getting fired on target database.
CODEReplicat process
replicat repname
assumetargetdefs
userid gguser@bbb password Oracle
dboptions suppresstriggers
map x.* ,target x.* (since same schema)
The extract files,pump files and replication are working fine.I also used the dbms_goldengate_auth.grant_admin_privilege for gguser.
Also I noticed when I give the dboptions suppresstriggers replication process doesnt startup with unrecognised word message when i give dboptions suppress triggers the replicat process does start is this the way it should be.i have gone through the docs and it should be supresstriggers.

I'm try to connect to databases with DBLINK. It works, but I drop the dblink to do it again in the final server. The problem that I now is that there is not any DBLINK in my database but I can see the data of the other database (with select 1 from DATABASE.TABLE)
Is my database saving the data of the other database without de DBLINK?

I am on Oracle 11.2.0.3 on Linux. In my production database, I am getting this alert, in the alert log:
--the below two lines are from alert log.
Error 604
trapped in 2PC on transaction 50.73.546578. Cleaning up.
--query from a data dictionary view
SQL> select count(*) from DBA_2PC_PENDING;
COUNT(*)

When I query the production database I see that there is one row in the DBA_2PC_PENDING view. But I dont' know how to identify which are the databases that are involved in this distributed transaction. That is my first issue - how to identify which are the two databases that are involved in the distributed transaction?
