List Exiting Databases In Oracle Server Using SQL Plus Command?
Feb 14, 2013
I am using Oracle database server and I want to show existing databases on that server. Are there any SQL plus command to list all databases there in the server?
I have oracle grid control 10.2, I want to get the list of databases and servers that was configured within the Grid, is there any query that I can use to get it from Grid database?
I have to migrate two different databases to oracle.i have made two Migration Repository for each to do the migration, migration is done.but i would like to know can it be done with one migration repository.if yes then with one is best way to do it.data of two databases is different but table and sp are 99% same.
But on my o.s I have archivelogs from log sequence 104 - 206 (I have not deleted them for long 1 month). It is not showing form 104 - 178. Since control file record time is 7 days it doesnt keep old archivelogs history.(i.e from 104-206) Hence it is showing only from 179 - 206
My question is
1)If we use rman recovery catalog will these info is maintained forever until deleted. And can i see them in list command. (i.e from 104-206) 2)If i use rman catalog then from where did rman get the information of archives and backup (for list and restore command) from catalog or from control file.
we are running SAP application against oracle database. say, if I use brspace or brtools (from SAP side) to shutdown or startup database or collect stats, does this mean it not recommend to use oracle command to shutdown/start & collect stats?
I have the task to migrate the total databases(Exact copy to be moved to another server).The current server is going for format.After I did the following steps I am getting the tablespaces(databases)-4 sizes same ,but I am facing issue like some default tablespaces i.e temp,system are not matching.
temp tablespace *************** current server - 4.0(approximately) Migrating server - 160 MB
System tablespace ***************** current server - 580 MB Migrating server - 220 MB
Also I checked the tables are also matching for the 4 databases.Also Provide the solution or method which is correct.
steps done for migrating(By me) ******************************** EXPORTING DATA USING DATAPUMP *********************************
1 From command prompt MKDIR 'c:oraclexeapp mp';
2 From SQL prompt conn system/kotak;
3 create or replace directory dmpdir as 'c:oraclexeapp mp';
4 grant read,write on directory dmpdir to kotak;
5 From command prompt
expdp system/kotak@xe full=Y directory=dmpdir dumpfile=xe.dmp logfile=expdpxe.log; IMPORTING DATA USING DATAPUMP ***************************** in another server machine
1 From SQL prompt conn system/kotak;
2 create or replace directory dmpdir as 'c:oraclexeapp mp';
while using top command it shows multiple processes usage.Actually we have 3 databases in the same server.how to find out which database process and user session hogging the cpu resources
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.
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'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 have cloned the database into another using DBMS_METADTA API (export the metadata in xml form and recreate it on destination). I need to synch these two periodically. I need to update the XML to synchronize the databases.
if you are using ShadowProtect to backup your Oracle databases. What are your experiences and the pros and cons in using ShadowProtect as the one and only backup/recovery tools for Oracle databases? Can the potential of ShadowProtect replaces the commonly use Oracle backup/recovery tools?
The reason why I raise this question is because my boss has the idea that ShadowProtect is THE best backup/recovery tools. Personally I don't think so, because there can be cases where we only need to recover the database and not the whole OS.
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(*) ---------- 1
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?
I want to compare two users on different databases, actaully there are two users one in user a on database a and another user b on database b they have same tables, and everytime when a table or object is created on user a (database a) i will take the table name ,procedure or any other object from user_objects based on ddl_created date and then i need to recreate the same on user b on database b, is there a way to find out tables which are not only created but also i need to check whether if there is any column added or any change in procedure or any other objects.Is there a way to generate the scripts based on list of objects selected from user_objects. all i want is.
a)Find out the list of objects added along with creation scripts b)find out the list of objects modified along with creation scripts.
How can we bring down the databases in oracle fail safe environment?
We have one database X in two server�s windows A & B with oracle fail safe environment. What procedure should we fallow to bring down the database X.
Today I was strangling to bring down the database because database was automatically coming up once brought down the database. what procedure should we follow to bring down the database in OFS environment.
