we have 7 databases running in a server .
OS : solaris
i want to add a new database on that server . So i want to find , whether we have a sufficient memory to add a new database . how to find it ?
If we want to know the number of instances, number of RAC databases and whole total disk space used by oracle (not file system size),1. Any script can be ran from OEM grid control against all instances/databases? or2. we have a repository unix server which has all tnsnames of whole databases, any script we can run from there?
View 5 Replies View RelatedI have the following setup
SQL> show parameter sga;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 3G
sga_target big integer 2G
from what I read I beleive this will initially grab 2GB of memory on startup and will grab up to to 3GB of memory total for the SGA. The "total" memory can be allocated to different peices of the SGA when needed but will never exceed 3GB. Is this correct or would these settings infringe on any available memory on a system that is already tight on memory?
Secondly, what happens if both these values are set to the same value?
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.

View 2 Replies View RelatedI 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?
I have Oracle 11g installed on AIX and I want to install another 11gR2 single instance in a different oracle home, will it be possible?
View 3 Replies View RelatedUsing 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?

View 3 Replies View RelatedI was reading the documentation for oracle 11gr2, with reference to URL>.....
The following examples show how to correctly choose the cluster key and set the HASH IS, SIZE, and HASHKEYS parameters. For all examples, assume that the data block size is 2K and that on average, 1950 bytes of each block is available data space (block size minus overhead).Note that 34 hash keys are assigned for each data block
how they arrive at 34 hash keys because another portion of the document states
This space determines the maximum number of cluster or hash values stored in a data block. If SIZE is not a divisor of the data block size, then Oracle Database uses the next largest divisor.
if that is the case, then number of hash keys should be 1900/55 = 34.55 which should have rounded up to 35.

by simply going to DBF file and seeing their size?
or
by exporting dump and seeing the size of that dump?

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.
We are running oracle9i database in windows 2000 server few months before i re sized the SGA to sga_max_size =800M and pga-aggregate_target to 400M, actually we have 4gb RAM out of the we are allocated 1200Mb for SGA and PGA.
My question is if the allocated memory got filled in SGA or PGA whether the system will show any error, because when I am querying from sql> show parameter ; the sga free memory is reducing daily what will happen when it reaches its max_size.
estimate the percentage of memory should i can allocate from the total physical memory (it is 6G) as attached in the image file as a print screen.
