Server Administration :: ORA-01658 / Unable To Create INITIAL Extent For Segment In Tablespace?
Aug 11, 2011I have executed the below statement to move a bulk of table from source table space-SHOP3_DATA to destination tablespace -LINUX_CATA. Before executing the statement the source table space was having 85% full message . While executing the statement this is giving the error for the source tablespace means the the tablespace is getting consumed in the source TS. Currently no-one is using the tablespace SHOP3_DATA' . If I add datafile to the SHOP3_DATA the problem may be solved but why the space is getting consumed in the source. Now the tablespace SHOP3_DATA is 95% full

What Will Be Initial Extent Size
Oct 29, 2010I've read the documentation that describes the storage management.I create a tablespace as:
CREATE TABLESPACE MY_TABLESPACE_NAME
DATAFILE 'path/filename1.dbf' SIZE 3000M AUTOEXTEND ON NEXT 200M MAXSIZE 4000M
LOGGING
ONLINE
PERMANENT
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M
BLOCKSIZE 8k
SEGMENT SPACE MANAGEMENT AUTO
FLASHBACK ON;
As the extent management is local, does it mean that any storage clause of the objects (tables, indexes etc.) placed in it isn't taken into consideration? I mean in a case of placing a table in the mentioned tablespace that has a storege parameters defined as follows:
CREATE TABLE MY_TABLE(
...
)
TABLESPACE MY_TABLESPACE_NAME
PCTFREE 10
INITRANS 1
MAXTRANS 255
STORAGE (
INITIAL 100M
NEXT 20M
MINEXTENTS 1
MAXEXTENTS 50
BUFFER_POOL DEFAULT
)
1. what will be the initial extent size? 1M or 100M?
2. what will be the next extent size? 1M or 20M?
3. will the maxextents parameter be taken into consideration?
4. when i'm sure the tablespace is dedicated to keep only one object [MY_TABLE], what should be the relation between the initial datafile size [filename1.dbf] and the initial extent size? Should they be iqual or doesn't matter?
5. as the SEGMENT SPACE MANAGEMENT is AUTO, the PCTFREE param doesn't make sense, right?
Small Extent Sizes In 11.2.0.3
Aug 12, 2013I did some google searches about large number of extents and ASSM. I see bits and pieces on the web. This is something I need to look at while testing an application. Not looking to go into 'why' I would use smaller extents, I just want to make sure I have what I need to look for during testing..Issues with massive numbers of extents:
1. DBA_EXTENTS query is really slow.
2. issues truncating tables (due to having to read lots of extents)
3. issues splitting maxvalue partitions and with dropping partitions.
4. if I stay away from ASSM, would this reduce these issues? Are there any other performance issues or other issues I need to know about to check when I do tests?
Any issues with query or insert wait time? The tables that would get smaller events would have thousands of partitions/sub-partitions . Most of these sub-partitions will be rather smaller.I just want to test for a variety of different cases. The 'why' will come out during testing.
Partitioned Table - What Extent Size To Be Set
Sep 28, 2012I have a partitioned table (one partition per month). Every month there are added about 1GB data. What extent size should I set? 1GB will be ok?
What if data will be greater than 1GB, adding new 1GB extent takes probably a lot of time and clients may see delays while they're inserting in this time? (it's OLTP system)
When new extent is allocated? Exact in time of lacking space in existing extent or before? Partitions are dropped after one year so free space isn't a problem.

Minimum Extent Error Creating Tables In Empty Tablespaces
Dec 30, 2010I am trying to restore to a backup instance on a backup server. When I try to recreate the tables I keep getting ORA-01659: unable to allocate MINEXTENTS. The tablespaces and datafiles on both servers show as the same size in OEM.
I have dropped all tables and OEM shows tablespaces are empty. Then I run a script to recreate all tables. Most of the tables don't get created because their TS is full. After the script to recreate all tables runs, the main tablespaces are full, more full than on the production machine. I have also tried ALTER TABLESPACE xxx COALESCE; on each tablespace right after dropping all tables and before recreating them to reclaim free space. Why is it full? I've only dropped and created the tables, there shouldn't be any data in them yet.
ORA-01659: unable to allocate MINEXTENTS beyond 2 in tablespace PLUS_T...The backup instance was already there, all I did was drop the tables. Here's what I ran on prod to build a script to recreate the tables on backup server. Got it off Burleson somewhere.

View 3 Replies View RelatedServer Administration :: How To Connect Oracle Client To Remote Server DB
Jun 29, 2013I'm trying to connect a oracle client application on the client machine to a remote oracle server on the server machine but i get a connection fail.
On the server machine I configured oracle server in the following way:
Installed oracle server. Created a database "DB_Test" with the database configuration assistant Created a LISTNER with the Oracle NET Manager with the following parameter:
Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521 Created "dbtest" service with the Oracle NET Manager with with the following parameter:
Service Name: "dbtest" Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521
All services on the server machine are running and I opened port number (1521) in the router. On the client machine I installed SQL PLUS and SQL Developer.
With SQL Plus as by the official documentation I have entered the following command:
CONNECT username/password@[//]host[:port][/service_name]. In my case is:
CONNECT SYSTEM/oracledb@//ENZOVAIO:1521/testdb.
With SQL Developer I have entered the same parameter.
But with both SQLPlus and SQL Developer the connection fails.
