What's the maximum size of the control file in one database ?
i calculated it according to the following steps:
SQL>SELECT (BLOCK_SIZE/1024/1024)*20000 MB FROM V$CONTROLFILE WHERE ROWNUM = 1;
MB
------
312.5
The maximum number of the data block in one control file is 20000.
I am having I/O issues if i create 20 GB DATAFILES on SMALL TABLE SPACE. guide me with the maximum size limit of data file that I can create in Windows 2003 32 bit server.

View 13 Replies View Relatedwe have an environment with many Oracle databases in different versions (v8, V9, V10 and V11). Besides that, there are many versions of the Oracle Client in use, ranging from V6 to V11. Many of the clients have a TNSnames.ORA and as was to eb expected, many of these are old as well with a lot of (by now) invalid information in there.
Is there any reasonable maximum size to the TNSnames.ORA file?What are the consequences from going over the max size? Are there alternatives to using TNSnames.ora which you would recommend?
I noticed my DB is generating a lot of "small" .arc files and I am usure why. As you can see from the v$log query my log file size is set to 50MB. But yet BLOCKS*BLOCK_SIZE never adds up to 50MB.
Is there anything else I can look into to see how to make the .arc files larger?

I am trying to create a new controlfile. I used "alter database backup controlfile to trace;" and then I copied and pasted the contents of the trace file into the .sql file. My sql script is

Actually, the name of my database was 'STAR' and I changed it to "FIVESTAR" int this .sql script. Now when I run this script with SQL> @ <path of my sql script>, it gives me the following errors:
ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed

I can not run the control file treace file,why?

I was doing some R&D on my test machine trying to understand how controlfile works. I started up my db and then deleted (renamed)the controlfiles at OS level. I was expecting the db to shutdown. But it dint. Moreover when i queried select name from v$controlfile; it was still reflecting the old controlfile names. To check if it was still functioning, i created a new tablespace with one file and it also got created without any error.
What i dint understand is how could the db still be running when the control file was'nt there and new tablespace and datafile get created? As i understand, whenever a new file is created, an entry is made in the control file. But when control file dint exist where was the data about new tablespace and datafile written?
I am storing customer's snaps in a table ( column's data type as LONG RAW) using oracle forms Webutil. Now there are 250 snaps in the table. The file type of these snaps is JPG with the average size 30KB.
I made a backup using export utility before storing these snaps and the exported DMP file's size was 36MB. Now after storing these just 250 snaps of 30KB the DMP file's size is gone over 300MB.
i need to change column's datatype? or some where in oracle forms's image item. Because on window's file system the size of these files is just 8MB.

1)How a single control file is enough to have all the transaction's SCN no for older transactions.
Eg - A transaction has the SCN 01 and after a month the new transaction's SCN is 502. Is the control file holding all those (01 to 502) SCN in it or just will have the latest SCN no (ie - 502).
I'm facing problem with archive log file size, Archive logs are generated with only of 90m or 92m or 94m(Variable sizes of less than 100m), Although i had set 100m for each of my redo log file.

I'm having a problem with SQL loader and the control file. I want to load a delimited file. The script will eventually be automated where the file name is passed in to the script, it's not a static name.
It's a simple SQL loader Unix script that I have created as follows
Unix file called test_load

load data
truncate

View 3 Replies View RelatedI have one tablespace PSINDEX with Maxsize of 6 GB. But when I query the tablespace its showing the BYTES is greater than MAXBYTES.
View 5 Replies View RelatedI am working to understand the space allocation of table with the value we provided with the data type. For that I have created a table with varchar2 and length 50. Size of table created is of 65536 Bytes. This is when we don't have any insertion in the table. Later when we insert some rows, total size if the segment still remain same that is 65536 bytes.
Now again when I created table with varchar2 and length this time is 500 but still it is created with same size that is 65536. So can you just explain, on what values segment size depends on and how the length effect the size & space allocation.
db_block_size is 8192.
