Any practical experience with composite partitioning range/list?

Hi,
I'm working on Oracle 9.2.0.4 and I plan to migrate several large range partitioned tables into range/list partitioned tables. I was wondering I anybody has some practical experience with this new feature (range/list composite partitioning) and if he encountered any bugs or "undocumented features" ?
Thanks for any feedback
Maurcie
PS: I'm not looking for any documentation about how to do it, I'm just wondering if anyone has some experience in a PRODUCTIVE environment.

You can also put the query in a parameter file so you don't have to worry about escaping characters.

Mac OS X is a smaller market, and, so far, and for whatever reason, a smaller target. Consequently, although major A/V vendors do usually have a Mac division, it seems to me that they employ for it the B-team. As a result, some Mac A/V tools create more problems than they solve.
Furthermore, as WZZZ rightly points out, all A/V tools (irrespective of platfom) fight yesterday's problem. They can only protect you against the threats they've already seen and analysed.
So, the question is: Do you need an A/V tool?
The people who say, "No, because there are no Mac viruses" are technically right, but in a very narrow sense. There are no Mac viruses—but there is Mac malware. MacDefender and iWork Services are examples; the recent Flashback infection—there've been threads dealing with it in this very forum for the past month—is another. So it really depends on what you do. The iWork Services Trojan Horse spread through a hacked download of Apple's iWork suite, distributed primarily through P2P file sharing. If you do that kind of stuff, you are at risk. Flashback spread through a Java vulnerability. If you browse the net with Java enabled, you are at risk.
Then there's the issue of exchanging files with Windows. If you work in a mixed Win/Mac environment, or exchange documents with others who use Windows, you may be the unwitting vector of infection, by transmitting Windows malware from one PC-using correspondent to another. The Win malware would not affect you in any way—but it would certainly affect them.
Therefore, the answer depends primarily on you.

Any *positive* experiences with iOS 8 on iPad 2?

Two related questions:
1. I'm trying to decide whether or not to install iOS 8 on my iPad 2. I've read quite a few posts explaining negative experiences. But has anyone had a positive experience? No challenges with the upgrade? Few to no problems with apps?
2. I am on my third iPad 2 due to hardware issues. My most-recent iPad 2 is only one month old. Will this make any difference whatsoever as to how it will respond to the upgrade? Or is it just a case of the iPad 2 being out of date hardware-wise? Not up to the task?

I still haven't upgraded from 7.0. However, last night I must not have been thinking properly, and I upgraded my Mac to Yosemite. I'm worried that my iPad and Mac will stop talking. So far, so good, but how long will they continue to support iCloud? (I didn't switch to iCloud Drive because iPad still on 7.0.)
With the 8.1 upgrade, did you note any improvements? Any problems?

I am interested in editing GoPro footage using Adobe Photoshop Premiere any have experience with that.

Wondering if this software is good for editing GoPro footage. Thanks

My GoPro workflow currently is:
- record with GoPro in Protune
- import GoPro MP4 into Premiere and edit
- convert GoPro MP4 to AVI using GoPro Studio (leaving same file name stored in sub-folder)
- 'offline' GoPro Premiere MP4 footage and 'relink' to AVI
- export media out of Premiere
Be careful with AVI files in Premiere as they crash my 2014.2 release 8.2.0(65) build. Solution I see to have AVI not crash Premiere is to turn off GPU Acceleration and use Software only.
After I re-link AVI files in Premiere, I leave my GPU Acceleration on and render out. I do not play the AVI with Premiere to avoid crashing. When I am re-linking the MP4 to the AVI, I am saving the project frequently due to Premiere crashing. I am exporting GoPro AVIs fine with GPU Acceleration on.
Premiere handles GoPro MP4 files fine. I could not tell you anything about Photoshop video editing if that is what you are asking.

Composite Partitioning Range-Hash Example

Probably everyone spotted it but the example in the concepts manual has a DD/MM/YYYY and MM/DD/YYYY mixup
Sorry if this is the wrong forum, but I just wanted to pass it on for correction

Apologies for the delay in responding to you.
Can you please specify the Doc Part number affected by this problem so I can inform the doc writer.

Your experience with Toshiba NB550D and Ubuntu

Hi,
does anyone of you have any practical experience with the laptop NB550D and running Ubuntu 11.04 (like did you have any problems with it )?
Thank you

Hi, sorry am not in Eu; i live in the US... the mini notebook model I have is NB505-N508BN. I think you should have equivalent models where you live. Just wanted to say that I have been able to successfully install and dual boot between Win 7 Starter and Kubuntu 11.04, on my netbook. In fact, i mostly use Kubuntu now, unless I need to make a backup of my system (which I do from Windows). It works great and I love it. Right now I am posting from a Firefox browser opened in Kubuntu.
I posted a long note and some screenshots of my Kubuntu 11.04 in the Toshiba mini netbooks users forum (US). please see this link if you are interested. Y'all have fun...

Moving Composite Partition table

Hi,
     i am using 11.2.0.3.0 version of oracle. I am planning to move a composite partition(range-hash) table into a different tablespace. And i was under assumption by moving the table/index subpartition , it will move the wholw table. Below is the scenario.
Now i have moved all the table/Index subpartition into the new tablespace, using below command.
    Alter table t1 move subpartition t1_sub1 tablespace new_tablespace;
Alter index id1 rebuild subpartition id1_sub1 tablespace new_ind1_tablespace;
but when i query dba_tab_subpartition i can see the new tablespace against the subpartition name but when i query the data dictionary dba_tab_partitions i am seeing the name of old tablespace against the partition name. And i execute below statement for moving the partition
    Alter table t1 move partition t1_p1 tablespace new_tablespace;
It gives error saying : ORA-14257: cannot move partition other than a range,list,system or hash partition.

Positive experiences with command validate

I killed a load process on Unix and got the error A write to file [data/essbase/app/PPU_FK/Ppu_Fk/ess00001.pag], from address [0x403bf4a8] with handle [19] to offset [1130184704] for [16384] bytes, failed with error [1130614] and system error [nnnnnnnnn] after [27] bytes.I tried to save something and issued the command validate in ESSCMD.Did you make any positive experiences with it? Does repair anything? Does it take long?Regards, Alexandru Draghici

The VALIDATE command does not repair any damage or corruption that may have happened in your database - it is a way to perform an integrity check as part of your load/build process.The length of time it takes will depend on the size of your database.Regards,Jade-------------------------Jade ColeSenior Business Intelligence ConsultantClarity [email protected]

AVOID Subpartition(list) to be created when Splitting Main Partition(range)

I have created a table structure as below:
CREATE TABLE TEST_SUBPARTITIONS_1
RECORD_ID INTEGER NOT NULL,
SUB_ID VARCHAR2(100),
COBDATE DATE,
DESC VARCHAR2(2000)
PARTITION BY RANGE (COBDATE)
SUBPARTITION BY list(SUB_ID)
PARTITION INITIAL_PARTITION VALUES LESS THAN (TO_DATE(' 2200-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE TBS_DATA
PCTFREE 10
INITRANS 1
MAXTRANS 255
STORAGE
INITIAL 64K
NEXT 1M
MINEXTENTS 1
MAXEXTENTS UNLIMITED
(SUBPARTITION INITIAL_SUBPARTITION VALUES ('INITIAL_DUMMY_SUB_ID') TABLESPACE TBS_DATA
CREATE UNIQUE INDEX TEST_SUBPARTITIONS_1_PK ON TEST_SUBPARTITIONS_1 (COBDATE, RECORD_ID, SUB_ID) LOCAL;
ALTER TABLE TEST_SUBPARTITIONS_1 ADD CONSTRAINT TEST_SUBPARTITIONS_1_PK PRIMARY KEY (COBDATE, RECORD_ID, SUB_ID);
I am partitioning the table based on range (COBDATE) and subpartitioning based on list (SUB_ID).
The table now is created with initial partitions and initial subpartition.
We are splitting the partitions in our procedure as below
ALTER TABLE TEST_SUBPARTITIONS_1 SPLIT PARTITION
TST_SUB_R21001231 AT (TO_DATE(20130220,'YYYYMMDD') ) INTO
     (PARTITION TST_SUB_R20130219 TABLESPACE TBS_DATA, PARTITION TST_SUB_R21001231)
The partition is getting split correctly with new partition as
TST_SUB_R20130219, but the subpartition is also created automatically with some 'SYS' name.
(i.e Name: SYS_SUBP693 , Values: INITIAL_DUMMY_SUB_ID)
This happens after every split of range by COBDATE.
Here it has created as below:
Partition          SubPartition
TST_SUB_R21001231     INITIAL_SUBPARTITION
TST_SUB_R20130219     SYS_SUBP693
TST_SUB_R20130220     SYS_SUBP694
TST_SUB_R20130221     SYS_SUBP695
I want to AVOID splitting subpartition when I split the main partition
i.e a SYS subpartition should not be created when I split the partition for COBDATE.
Let me know how do I avoid this in main "alter statement" above?
Any other solution?     I do not want to drop the SYS subpartition later, instead want it to avoid creating only when I split the partition.

The subpartitions aren't being split. Oracle is creating new subpartitions for the new partition. The subpartitions need to exist since that is where the data is stored.
You can avoid the SYS prefix on the name though by using a different naming convention.
See the 'Splitting a *-List Partition' section of the VLDB and Partitioning Guide
http://docs.oracle.com/cd/E11882_01/server.112/e25523/part_admin002.htm#i1008028
>
The ALTER TABLE ... SPLIT PARTITION statement provides no means of specifically naming subpartitions resulting from the split of a partition in a composite partitioned table. However, for those subpartitions in the parent partition with names of the form partition name_subpartition name, the database generates corresponding names in the newly created subpartitions using the new partition names. All other subpartitions are assigned system generated names of the form SYS_SUBPn. System generated names are also assigned for the subpartitions of any partition resulting from the split for which a name is not specified. Unnamed partitions are assigned a system generated partition name of the form SYS_Pn.

ORA-14291: cannot EXCHANGE a composite partition with a non-partitioned ta

How do I resolve the below issue. I need to create a temp table and then do a exchange partition to the temp table using certain condition . The main table
edc.edc_log_test has partition and subpartition. I used the below sql to create the temp table. How can I create the temp table with partition so that I do not get the mentioned error.
edc.edc_log_test has
PARTITION BY RANGE(CAPTURE_DATE)
SUBPARTITION BY LIST(TRAN_NBR)
l_ddl := 'create table ' || p_object_owner_in || '.' ||
p_part_subpart_name || ' as select * from ' ||
p_object_owner_in || '.' || p_object_name_in || ' where 1=2';
l_ddl := ' ALTER TABLE ' || p_object_owner_in || '.' ||
p_object_name_in || ' EXCHANGE PARTITION ' ||
p_part_subpart_name || ' WITH TABLE ' ||
p_object_owner_in || '.' || p_part_subpart_name ||
' EXCLUDING INDEXES WITHOUT VALIDATION '; *
ORA-14291: cannot EXCHANGE a composite partition with a non-partitioned table

The subpartitioning scheme of the composite partitioned table must be matched by a partitioning scheme on the temporary table.
In your case you need to list partition your temporary table on TRAN_NBR

Do I need to run and anti virus program with MAC OSX Lion? Have heard different opinions!
You will continue to hear different opinions here, where thoughts range everywhere between "anti-virus software is the evil spawn of Satan" to "anyone not running anti-virus software is a fool."
Truth is, this is still a very personal decision on a Mac. Depending on circumstances, it is still very easily possible to stay safe without using anti-virus software, but circumstances and personal preferences vary widely. Besides which, anti-virus software cannot even remotely provide you a guarantee of protection!
To learn how to stay safe (with or without anti-virus software), and how to decide whether to use anti-virus software, see my Mac Malware Guide.

SCCM Query for any PC with 2 partitions?

I'm trying to find a query that will allow me to tell any computer in our network that has 2 partitions. When we deploy our Win7 through SCCM it has only the 1 partition and doesn't have the 100MB partition that is created if you install via a CD.
Problem is we have some old 7 computers that we need to find to change the way we deploy bitlocker and MBAM through SCCM and if i can find the ones with 2 partitions then I'll have a much easier job. Does anyone know how to do that via SCCM?

Hi, This query will list all computers with a disk 0 parition 1, that should mean they have two partitions. I got some strange result on one of my HP Laptops though which had 4, But you could give it a try.
select SMS_R_System.Name, SMS_G_System_PARTITION.DeviceID from SMS_R_System inner join SMS_G_System_PARTITION on SMS_G_System_PARTITION.ResourceId = SMS_R_System.ResourceId where SMS_G_System_PARTITION.DeviceID = "Disk #0, Partition #1"

Any experiences with editing 50+ MB files.

Hi,
I'm thinking about getting a new camera later this year which outputs file sizes of 50-100 MB. This would mean that I also have to upgrade my Mac since I feel that my 2008 C2D (8MB ram and SSD) has reached it's limit at 25MB (16 MP) raw files.
Does anyone have experience with such large files? What Mac do you use and what would you recommend in terms of performance? I'd love to have a MacBook Air but it might not be powerful enough. Not sure about that. How big is the practical difference in performance between the MBA, MBP, Mini, iMac?
Thanks for any advice...
p.

We do not know specifics of how Aperture utilizes discrete graphics cards but in the past solid graphics were a necessity. E.g. Apple's strongest G5 tower would not run Aperture until an upgraded graphics card was installed. Boxes that rely only on integrated graphics like MBAs and Minis are not recommended.
Usually a good general feeling of relative graphics performance can be obtained by diligently perusing the tests at barefeats.com. Note that Aperture-specific testing is IMO only marginally relevant, but overall graphics app performance is IMO very relevant.
I use a 17" i7 MBP with SSD and 16 GB RAM. It works well as a desktop-replacement box, but my RAW files are only 20-30 MB size. My Aperture/Photoshop workflow was paging out at 8 GB RAM before I upgraded to 16 GB RAM. Odds are that 16 GB will work fine with your big files but if I was moving to a MF DSLR I would be a bit concerned about only having 16 GB RAM as the maximum available.
Personally to obtain mobility I would sacrifice the ability to to exceed 16 GB RAM but I would only do it with Apple's strongest mobile GPU available at purchase time. I.e., the top MBP.
If you do choose to give up mobility plan on a 32-GB box when price comparing. Personally I would go with a cylindrical Mac Pro not an iMac because the stock Mac Pro graphics are far stronger and the Mac Pro is upgradable.
All the good choices (MP, top MBP, top iMac) all have more than enough CPU. IMO in 2014 we can mostly ignore CPU as regards purchase decision making on the top boxes.
512 GB SSD for boot is IMO a mandatory minimum for any new Aperture box in 2014. Note also that if you do create a RAM-intensive workflow that does page out 16 GB RAM the deleterious effects of paging out are substantially ameliorated by SSD.

I'm currently dealing with this issue myself, except that my rMBP has NO articles in the reading list. It's a brand new rMBP too, purchased just this week, with the 2.6 Ghz Processor & 16GB of RAM.
Let's see what we can find. I may just take it back to the Apple Store.
