Any Reasonable Maximum Size To TNSnames.ORA File?

Dec 28, 2010

we 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?

Server Administration :: ARC File Size Too Small?

Oct 2, 2012

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?

SQL> select group#, thread#, bytes from v$log;
---------- ---------- ----------
1 1 52428800
2 1 52428800
3 2 52428800
4 2 52428800

select blocks, block_size, blocks*block_size from v$archived_log where sequence# between 63876 and 72851 and thread# = 1

28 512 14336

Server Administration :: Size Storing JPG File In Database

Feb 13, 2012

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.

Server Administration :: Size Of Data Of Table

Oct 20, 2011

ops$tkyte@DEV8I.WORLD> select blocks, empty_blocks,
2 avg_space, num_freelist_blocks
3 from user_tables
4 where table_name = 'T'
5 /

---------- ------------ ---------- -------------------
19 35 2810 3

Ok, the above shows us:

- we have 55 blocks allocated to the table (still)
- 35 blocks are totally empty (above the HWM)
- 19 blocks contains data (the other block is used by the system)
- we have an average of about 2.8k free on each block used.

Therefore, our table

- consumes 19 blocks of storage in total.
- of which 19 blocks * 8k blocksize - 19 block * 2.8k free = 98k is used for our data.

not too sure this calculation is accurate for getting the size (data)of the table.

Export/Import/SQL Loader :: Field In Data File Exceeds Maximum Length?

Apr 22, 2013

I am struggling with a simple data load using sqlldr

Ref: I am running Oracle 11.2 on Linux 5.7.
Here is my table:
SQL> desc ntwkrep.CARD
Name                                                              Null?    Type


Looking at the actual data and counting the characters for the "REALIZES" column data, I see that it is roughly slightly over 1000 characters.

So, attempting various ideas to fix the problem, I tried changing nls_length_semantics to "char" and recreating the table, but this still didn't work and still got the same data load errors on the same rows.

Then, I changed nls_length_semantics back to byte and recreated the table again.This time, I altered the table manually as:

Table altered.

SQL> desc ntwkrep.card
Name                                                              Null?    Type
----------------------------------------------------------------- -------- --------------------------------------------
CIM_DESCRIPTION                                                            VARCHAR2(255)
CIM_NAME                                                          NOT NULL VARCHAR2(255)
COMPOSEDOF                                                                 VARCHAR2(4000)


Here is a copy of the first row of data which fails to load every time no matter how I change the "REALIZES" column in the table.

other(1)`CARD-mes-fhnb-bldg-137/1`  `other(1)`CARD-mes-fhnb-bldg-137/1 [other(1)]`HwVersion:C0|SwVersion:12.2(40)SE|Serial#:FOC1302U2S6|` Chassis::CHASSIS-mes-fhnb-bldg-137, Switch::mes-fhnb-bldg-137 ` Port::PORT-mes-fhnb-bldg-137/1.23, Port::PORT-mes-fhnb-bldg-137/1.21, Port::PORT-mes-fhnb-bldg-137/1.5, Port::PORT-mes-fhnb-bldg-137/1.7, Port::PORT-mes-fhnb-bldg-137/1.14, Port::PORT-mes-fhnb-bldg-
