How SMON coalesces free space in oracle 9i and 10g
how SMON coalesces free space in oracle 9i and 10g?
Is it doing same as it was behaving in oracle 7 like looking through free extent table every five minutes (sys.fet$) to see if there are any adjacent free extents that can be coalesced into a single extent, and on every 25th cycle (i.e. every two hours and five minutes) it looks at the segment table (sys.seg$) to see if there are any temporary segments that need to be eliminated, as explained by jonathan lewis?
what are extent and segment tables available in oracle 9i and 10g like sys.fet$ and sys.seg$ in oracle7?

and automatic segment management in 10g

BR1049W Not enough free space in /oracle/SID/sapdata
Hi Everybody,
I am trying to extend a tablespace through BR*tools. However I'm getting the Warning :
BR1049W Not enough free space in /oracle/SID/sapdata1 for total maximum size of all database files of tablespace...
As you could see below, I have still about 100 GB free on this logical volume.
Filesystem GB blocks Free %Used Iused %Iused Mounted on
/dev/sapdata_lvSID 899.88 99.97 89% 179 1% /oracle/SID/sapdata1
I wanted to add a datafile (size = 32GB), it didn't work.
Best regards
LatifCan you please provide the SQL statement the brtools is issuing when adding the datafile. Probably ,for all the datafiles which are in /oracle/SID/sapdata1 , if the max size is added up , then the value is greater than the filesystem size. Please check in dba_data_files the maximum size upto which datafiles in sapdata1 can extend.
Use this to check:
select sum(MAXBYTES)/1024/1024/1024 from dba_data_files where FILE_NAME like '%sapdata1%';
if the value returned + the new datafile max size is > file system size you will get the above error. -

Hello,
Let's see if we can find out where the big users of space are first.
How much free space is on the HD, where has all the space gone?

How do you free space on the startup disk
how do you free space on the startup disk
If your disk is 80% full that is normal. Time Machine uses up to 80% of the disk space for local snapshots. To get rid of these snapshots simply plug in your Time Machine backup drive and run a backup.
If you have less than 20% disk space then it is time to roll up your sleeves and search for what you can delete and what you can offload to another disk.
If you have less than 10 GB you definitely need to delete or offload some files. You may want to maintain at least 20 GB of free space so when your disk starts filling again it will have some room before it hits that 10 GB mark again. More headroom is better. If you let the space fall much below 9 GB you might not be able to boot your machine.
Initial easy steps to gain disk space:
- Delete all files in the Downloads folder.
- Empty the trash.
- Start iPhoto, empty its trash and restart the computer.
Deleting files:
Run a Time Machine (or other) backup since you are about to delete and move files and you may need to recover from any inadvertent mistakes or decisions. You will need one external hard drive for your Time Machine (or other) backup and a second one onto which you will offload some files.
Then use the free application OmniDiskSweeper http://www.omnigroup.com/more to explore your volume in descending order by size so you can attack the problem from the top down, deleting the largest unwanted files first. Delete with caution and do not delete any system files. Remember to empty the trash after trashing the files.
Moving files:
Consider moving some of the no-often-used large files or directories to an external disk. Use ODS again to find them.
As noted above this will be at least your second hard drive. Your first one(s) is/are for your Time Machine (or other) backup(s). Do not offload files onto a Time Machine disk.
Format the second drive as Mac OS Extended (journaled). Using OWS to find large files/folders and copy them from the system drive to the external hard drive and delete them from your internal drive.
Then > System Preferences > Time Machine > Options… > Remove the offload HD name from the exclusions list.
Now both your system disk and your external offload disk will be backed up onto your Time Machine disk.

Erased free space in Disk Utility, and after it finished it kept a DMG there.
I erased free space in Disk Utility, and after it finished it kept a DMG there called "DeveloperDiskImage.dmg", why is it left behind? can it be deleted? how? if erasing free space is supposed to help get memory and remove all the files truly, it shouldnt be creating anything, it created a DMG at the start, but it went away, after a hour and a half it made the DeveloperDiskImage, i went to eat dinner and when i came back it was done but that was left.
Delete it. Erasing the free space isn't supposed to free up any space; it's there in case someone deleted a file insecurely when they meant to securely delete it.

How to manage the space between a table and its title?
Have tables where titles are very close to the main text and need a couple of points to separate these elements. How to reshape this space?
1. Titles were separated by a return that is not visible... (any code is revealed by ID)
2. When a Return is inserted after the title, nothing happens aparently, but this return is now visible and could be used as a «paragraph space after» value:
3. A solution could be Grep to catch the end of paragraph assigned to titles to insert a return;
but Grep only catches the right border of the table (the yellow mark shows the big blinking cursor);
Grep cannot see the end of paragraph in the tables's title.
It another method?
Basically, how to modify the space between a table and ists titleI think you and Bob are not in synch here.
Bob suggested that you could use paragraph spacing, but for that to work you do need to use separate paragraphs for the title and table, which you don't seem to be doing. Using GREP to find the end of the paragraph only works if there IS and end to the paragraph. As far as I know there is now meta-character to use in Find/Change that would allow you to find a table and insert a paragraph break ahead of it, but I bet it could be scripted.
I'm not quite sure what you were trying to find in the GREP you posted. Did you actually have a paragraph return inserted already after the title? In that case you only need to redefine the style for that paragraph to add the space (or redefine the style for the paragraph that holds the table itself). You don't need the GREP. But the reason it does nothing is that you've found a location -- the end of the paragraph, but haven't found any actual text to modify. To do anything you would need to use something like .$
But back to NOT having a separate paragraph... If you put the cursor in any table cell and go to Table Options > Table Setup tab you'll see fields to set space before and after the table that should do what you want. That was the second part of what he posted. -
Issue with .profile for oracle 9i and 10g
Here I have six oracle 9i databases on one box. I am going to upgrade five of them to oracle 10g and want to keep one database RCAT in oracle 9i for one or two week.
So, when I do upgrade I have to setup oracle home for 10g and also profile for oracle user for 10g (correct me if I m wrong). But now I want one database RCAT on oracle 9i. How can I take care of this.
I mean how I will handle profile and all other thing for oracle 9i and 10g at the same time.
Thanks,
VishalInstall 10g under the same OS user as 9i, of course on a different Oracle Home. Then you configure your .profile consequently. Just as an example, this is my .bash_profile with 10g and 11g with the same oracle OS user :
[oracle@linux5 ~]$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc

Data Replication between Oracle 9i and 10g
Hello,
I have a question regarding possible Replication Models between Oracle 9i and 10g. Does anybody know a possible way to syncronize the schema data between a 9i and 10g database in realtime?
If yes can you please post perhaps a link with a kind of how to?
Many thanks to all,
Bob...You can read this metalink note 370850.1 - there are bit more ways of replication discussed.
Yes, platforms can be different, but recomendation is to use the same platform for both databases. -
Query using Materalized view in oracle 9i and 10g
Hello
There are snapshots (materialized view) used in my application. We have recently migrated from 9i to 10g release 2 database.
After migration i have observed explain plan of query which is using materialized view and i found in 9i oracle treating materalized view as table. In 10g oracle is considerting it as MVIEW only (MAT_VIEW ACCESS BY INDEX ROWID). However in 10g cost of query which is using materialized view is much higher than 9i. And execution time is also random.
Can anbody pls. expalin diff. of materalized view access in oracle 9i and 10g.
Thankscan you post your query with explain plan for both 9i version and 10g version.
Thanks,

Oracle 9i and 10g in one computer
Could I install oracle 10g in computer where 9i is instaled. I want that both oracle is instal and test oracle 9i and 10g. Could I run oracle database 9i and 10g together and I use both of the database?
Thanks for answer.
Rafal DmitrowskiI would also suggest caution if you have a Windows server. While it is certainly possible to have both running, there are some issues with separate 9i and 10g homes on a Windows machine, things like the Oracle Home Selector doesn't work with 10g Oracle Homes. I wouldn't be overly concerned if you are dealing with development laptops, but I would make sure to do some testing before installing 10g on a production server with 9i already installed.

Buddhikewhen I was trying to up the database it is looking for another listener
and massage coming listener is not running...Not clear. The database does not look for a listener, maybe you got that error when trying to connect ?
Do you have a listener 10g service ? Did you start it ? If not, please try the following :
C:\> set ORACLE_HOME=<Your 10g Home>
C:\> set PATH=%ORACLE_HOME%\bin;%PATH%
C:\> lsnrctl start
wait up to a minute, then execute
C:\> lsnrctl status

Oracle 9i and 10G professionals required
Hi All,
A company in Tanzania is looking for Oracle 9i and 10G professionals for immediate requirement. Those who are looking for change and has 4 to 5 years experience can send in your resumes to [email protected] Indians are preffered. Mention "ORJOB#040820081411" in the subject.
Kindly send in your resume as early as possible.
Thank you.You can try setting the SGA to a low value and bring up both the databases. I don't think it should be too slow provided you are not running other windows programs.
If you are really interested in trying out new products you can also explore the option of installing VMware, creating virtual machines & installing Linux, and then playing with the different Oracle products. Doing this will at least keep your main windows operating system clean.
