Ipad space management

Hi. Basic stats:
iPAD4 - 64
iOS 7.1 (upgraded 20 minutes ago as my first attempt to resolve this problem)
laptop with windows 7.
Scenario 1: Sync music with "automatically fill free space with songs". Result: 9GB free.
Scenario 2: Sync music with "entire music library". Result: While I have 21GB free, I still get an error because I need more space (4 GB more space).
The screen shots were taken 2 minutes apart and show significantly different 'free space' available (I removed the movies and YouTube apps so I should have no videos in both scenarios).
I don't understand this contradiction.
Thank you,

Thanks for offering assistance.
I could understand you totally if the space taken by 'other' was a constantly high value, but it is not. It jumps up at random and seems to be affected most when some kind of sync or update activity is happening.
In settings the storage indicated across all apps is in total less than 5gb and remains constant.
I have seen it literally jump from 8.6gb free space to zero in seconds whilst doing nothing at all other than opening the music app or a calendar. 11gb was the biggest jump so far and forced me to factory restore and recover from backup just before going away for a family holiday this weekend.
I suspect there is an OS process using the space for housekeeping of some sort, but I cannot see which it is as the system info app I paid for does not give more detail. This happens with no apps loaded other than calendar, music, email.
Does the iPad use a virtual disk when it's out of memory or something? Would be useful to know how iOS manages when it's got too much to do.
But then again, I shouldn't have to debug the OS should I? Surely not....

ASSM (Automatic Segment Space Management)

Hi Folks.
I have a severe problem regarding Buffer Busy Waits.
I have deceided to implement ASSM (Automatic Segment Space Management).
Please assist....is the approch OK & how should i apply this in a existing tablespace (pls also specify the syntax & other constraints that should be taken care of)....
Waiting for reply ... & thanks a lot in advance....

ASSM is a good feature to use, but, you need to kill the culprit instaed of simply MOVING ON.
If creating a new tablespace with ASSM, moving objects from Non-ASSM to the new tablespace is a problem, then, think of the following:
First of all, findout which object type is causing BBW, is it rollback/undo header, undo/rollback block, segment headere or what?
You need to review the P3 value(reason code) of BBW wait event.
Try to review the following dynamic views, before you decide to MOVE on.
v$waitstat (segment header)
v$segment_statistics(read the oracle docs. how to use this view and which parameter need to set in order to enable this feature).

Problem about space management of archived log files

Dear friends,
I have a problem about space management of archived log files.
my database is Oracle 10g release 1 running in archivelog mode. I use OEM(web based) to config all the backup and recovery settings.
I config "Flash Recovery Area" to do backup and recovery automatically. my daily backup schedule is every night at 2:00am. and my backup setting is "disk settings"--"compressed backup set". the following is the RMAN script:
Daily Script:
run {
allocate channel oem_disk_backup device type disk;
recover copy of database with tag 'ORA$OEM_LEVEL_0';
backup incremental level 1 cumulative copies=1 for recover of copy with tag 'ORA$OEM_LEVEL_0' database;
the retention policy is the second choice, that is "Retain backups that are necessary for a recovery to any time within the specified number of days (point-in-time recovery)". the recovery window is 1 day.
I assign enough space for flash recovery area. my database size is about 2G. I assign 20G as flash recovery area.
now here is the problem, through oracle online manual, it said oracle can manage the flash recovery area automatically, that is, when the space is full, it can delete the obsolete archived log files. but in fact, it never works! whenever the space is full, the database will hang up! besides, the status of archived log files is very strange, for example, it can change "obsolete" stauts from "yes" to "no", and then from "no" to "yes". I really have no idea about this! even though I know oracle usually keep archived files for some longer days than retention policy, but I really don't know why the obsolete status can change automatically. although I can write a schedule job to delete obsolete archived files every day, but I just want to know the reason. my goal is to backup all the files on disk and let oracle automatically manage them.
also, there is another problem about archive mode. I have two oracle 10g databases(release one), the size of db1 is more than 20G, the size of db2 is about 2G. both of them have the same backup and recovery policy, except I assign more flash recovery area for db1. both of them are on archive mode. both of nearly nobody access except for the schedule backup job and sometime I will admin through oem. the strange thing is that the number of archived log files of smaller database, db2, are much bigger than ones of bigger database. also the same situation for the size of the flashback logs for point-in-time recovery. (I enable flashback logging for fast database point-in-time recovery, the flashback retention time is 24 hours.) I found the memory utility of smaller database is higher than bigger database. nearly all the time the smaller database's memory utility keeps more than 99%. while the bigger one's memory utility keeps about 97%. (I enable "Automatic Shared Memory Management" on both databases.) but both database's cup and queue are very low. I'm nearly sure no one hack the databases. so I really have no idea why the same backup and recovery policy will result so different result, especially the smaller one produces more redo logs than bigger one. does there anyone happen to know the reason or how should I do to check the reason?
by the way, I found web based OEM can't reflect the correct database status when the database shutdown abnormally. for example, if the database hang up because of out of flash recovery area, after I assign more flash recovery area space and then restart the database, the OEM usually can't reflect the correct database status. I must restart OEM manually to correctly reflect the current database status. does there anyone know in what situation I should restart OEM to reflect the correct database status?
sorry for the long message, I just want to describe in details to easy diagnosis.
any hint will be greatly appreciated!
Sammy

thank you very much, in fact, my site's oracle never works about managing archive files automatically although I have tried all my best. at last, I made a job running daily to check the archive files and delete them.
thanks again.

Migration LONG to LOB in manual space management tablespaces

Hi everyone,
We have Netweaver 7.0 and Oracle 11g and we are considering to migrate our manual tablespaces to ASSM. The first problem we've found is we can't do that online due to the LONG data type. So we decided to migrate LONG to LOB first. Note 835552 says that for Oracle version 11g the conversion is from LONG to SECUREFILE. But we follow seeking notes and in 1426979 (Oracle 11g: SecureFiles - The new way to store LOB data) one of the prerequisites for the conversion is to use ASSM tablespaces.
At this point, we can't migrate (online) to ASSM due to LONG data and neither can migrate to SECUREFILE due to the ASSM.
My question is: is it possible to make the migration from LONG to SECUREFILE specifying in the brspace a new tablespace with ASSM?
Thanks in advanced.

Hello
It is in fact possible to reorganize segment to a specific target tablespace using brspace option -n|-newts
brspace -u / -f tbreorg -a long2lob -o sapsr3 -s <source_tablesapce> -t allsel -n <target_tablespace_in_ASSM>
It is odd that in 11g you are not in ASSM, so you upgrade to that version and never performed tablespace reorg ?
620803 - Oracle 9i: Automatic Segment Space Management
The new ASSM function is available as of Oracle Release 9i. As of Oracle 10g, ASSM is already contained in the standard system, and new tablespaces are by default created as ASSM tablespaces.

Very disappointing why do I need a camera on my iPad to manage edit photos in new iPhoto app?

Very disappointing why do I need a camera on my iPad to manage edit photos in new iPhoto app?

That's just a visual differentiator so folks can easily tell if it will run on their machine. The difference is the RAM and processor in the iPad 2 and iPad (New). The camera has nothing to do with the physical requirements.

White Space Management

Digging through the web trying to solve some white space
issues, i stumbled upon the CF Administrator setting in CFMX7
called White Space Management (under Server Settings). Enabling
this reduces the size of pages that are parsed (obviously), but are
there any consequences of enabling it? If there are not any
consequences, then why is it not enabled by default in CFAdmin?

i'm not sure the CF comment solution will work as
intended...from what i've read, the manual way to do it is to
either use the <cfsilent> tag (which suppresses all output to
the buffer) or use <cfsetting enablecfoutputonly="true"> to
only output to the buffer between cfoutput tags.
I'm thinking that the whtie space management option is a
solution to having to use these tags.
My question really is, is there a performance hit for using
it? how much? and does using it effect anything? (i've heard other
comments on how it sometimes interferes with using the cfmail
tag...which i'm not too worried about since we changed our mailer
to use something other than cfmail)

DB02:Space management/Segments/Most allocated extents in any segment

Hi ,
in My SAP server: DB02 > Oracle Database Administration > Alerts > Alert monitor, there are few red alerts.

Hi,
What is your Oracle database version.? If it is 9i or 10g then you can ignore this warning as from Oracle uses Localy managed Tablespaces.
Please check below mentioned SAP notes, it may help you.
Note 599694 - LMTS autoallocate: Extent allocation

How to change segment space management (to manual)

How do I change the segment space management for a tablespace, from auto to manual
I can find documentation, to create tablespaces, and set them to auto, but nothing yet to change them from auto to manual.

I just found out, that I am confusing 2 subjects here: segment space management, and auto extensibility. My apologies ....... still new with Oracle :-o
Ok, to change autoextend to manual, do I do this on data_file level ? Do I only need to change this on the last datafile of a tablespace ?

Datafile - space management

Hi,
Which is teh best practice in creating a tablespace? We have our production db on solaris. We are in teh process of migrating teh db into a linux box.
Our tablespaces comprises of one datafile each, and these datafiles are of size mostly over 3-4 gb
Is it advisable to create tablespace with multiple datafiles( eg three datafiles of one 1gb each) so that this I/O overhead is distributed equally among teh files.
Suppose tehre are more than one datafile for a tablespace..
How does data get stored in these files? I mean does these files get filled concurrently or does the second datafile start filling up only after the first datafile runs out of space?
Pls advise..
I want to know whether i have to split the large datafiles i have for my tablespaces when i create these tablespaces in teh linux box.
Pls advise

Hi,
>>I want to know how datafiles are wriitten..like if teh 2'nd datafile starts filling only if teh 1'st datifile is filled up
No. There is no order or rule for DBWn background process to writes on data files when a tablespace there are many data files, and 2'nd datafile can be used even if 1'st is not complete filled.
Look at the example below:

Segment space management

hai experts
can anyone tell me the reason why system tablespace's segment space management is manual. any link for the description

thanks Jonathan Ferreira
want to know why manual management is made as
default for system tablespace
hen auto space management will reduce the burden of a
DBA and make space management easyIf I had to make a guess, I would suggest that since the system tablespace contains rollback (undo) segments, ASSM cannot be used. With ASSM, the extent size starts small (64KB) and grows to 1MB, 8MB, etc. as additional extents are added to segments.
Since regular users should not be using the SYSTEM tablespace for inserts/updates/undo, there should be minimal burden for the DBA in managing that tablespace.

Space Management auto in Existing tablespace

Hi,
I already have several tablespaces for which I want to use/transfer to automatic space management, is it possible if yes, then How, Thanks in advance.
khawar.

If syed khawar ekram really is asking about ASM, automatic storage management, available with 10g then I think the answer is the same: Create a new tablespace using ASM files and migrate the objects.
I find conversion of dictionary managed tablespaces to locally managed using dbms_space_admin to not be worth the effort since your only option is the auto-allocate storage method and the procedure does not rebuild the objects leaving the tablespace a hodgepod of whatever happens to be there. It is generally worth the efford to build a new tablespace and migrate the objects.

Space management oracle

Hi all,
Greetings of the day..
I have few doubts about the space management in ASSM tablespace.
1.Does ALTER TABLE SHRINK COMPACT needs ALTER TABLE ENABLE ROW MOVEMENT to be fired prior
2. I have table having fragmentation and materialized views on top of it updating with ROWID' s , how can i defragment the table without dropping the MVS
Thanks,
Uday

I'm not sure what you're showing here. Is this showing why you believe the table is fragmented? It shows that the table has some reclaimable space. That's not normally what people are concerned about when they talk about "fragmentation".
Note that if you use the \ tag (6 characters, all lower case) before and after cutting and pasting fixed format data (such as the output of SQL statements), you'll preserve the white space and make your posts much easier to read.

White space management gone on reboot

I have a strange problem here. Anytime we reboot our server,
the setting we have selected (on) for white space management in the
CF admin disappears. We can re-enable it easily of course, this is
just a mystery we would like to solve. Any ideas?
Server Details
Server Product ColdFusion MX
Version 7,0,2,142559
Edition Standard
Operating System Windows 2003
OS Version 5.2

I have noticed that numerous settings in my cold fusion
administrator are reset each time The server is rebooted or the
Cold Fusion service is restarted. These include white space
management, global script protection, and specific settings that
are needed to individual dsn settings. These can not all be
resolved by adding processing directives to the application.cfm. Is
this issue related to the fact that my only interaction with my
server is through a terminal services (RDP) connection?

Disk Space management

Is there a Disk Space management utility for Macs as there is for Windows. I had to re-install my Leopard OS and I've just lost 10 Gb of space. It may be something to do with archiving but a bit mysterious! You can probably tell from this that my computing knowledge isn't great!!!

There's a free program called GrandPerspective that I like.
http://grandperspectiv.sourceforge.net/
There are some other programs, as covered in this MacWorld article
