IllegalMonitorStateException on some queries

Hi,
Some SELECT statements in my java code consistently cause exceptions and Oracle core dumps.
Here is one example:
SELECT COUNT(H.harvest_id) FROM nm_harvest H , nm_messages M WHERE H.msg_uid=M.msg_uid AND M.user_id=1 AND H.harvest_type='foo' AND M.receive_date BETWEEN (TRUNC(SYSDATE, 'IW') -7) AND TRUNC(SYSDATE, 'IW')
Can anyone see anything wrong with the statement above?
This is what it throws:
java.lang.IllegalMonitorStateException: current thread not owner

Thanks for the reply Sri!
The restriction on Infocube wouldn't work either because I have a combination of queries I want to allow and prevent on the same InfoProvider.
That option got me thinking though... I think another solution would be to create a MultiProvider, copy the queries I need to restrict to that new MultiProvider and then use a role based restriction. The only problem would be that my naming convention for Queries uses the InfoProvider as part of the technical name so I would have to change the names of queries too. (Not to mention the process of creating several MPs and copying the Qs)
The other option you provide sounds feasible. Is it possible to change the owner of a query after creation? is it something you could easily do everytime you want to allow the editing of the Query?
Let me put this example:
a. User X creates a query that we want to control so noone can edit it before authorization.
assuming the option to restrict by query owner:
b. We change the owner of the query.
c. The Query needs to be modified. I change the owner again to user X.
d. After the modification is done, change the owner of the query again.
Using this scenario I think I could have a pretty decent solution to my need. Do you think it could work? It heavily depends on being able to modify the owner of the query every time I need to edit or restrict its modification.
Thanks for the time to help me out,
JD

I have some queries usage of RAID 1 on OSX

Hi there
I apologise for the length of this question, but there's quite a bit of relevant data. I work in a small typesetting company (<10 employees) and since a HDD failed on an old G4 iMac that we used as a data archive we have learnt that without our data we are nothing. I have now been asked to implement a more reliable back up/recovery system (with minimum downtime) that increases the 'safety' of our customer's data. Rebuilding the archive took days to sort out and because the archive was constantly accessed by our production macs and a couple of PC as well, it hit us hard.
We are looking into turning an old G5 Powermac (1.8Gz single processor 2.5Gb RAM) into a RAID 1 (mirrored) system with 2 x 1TB SATA drives using Disk Utility. We would have this to protect against one HD failing and losing customers' data. I understand that this is not a back up system, just something that would protect customer's data should a drive critically fail. I have some queries regarding how this works though.
1) How much (if any) maintenance is required on a RAID system? None of use are IT specialists - just typesetters with a bit of technical knowledge.
2) Is a mirrored RAID system reliable, considering multiple people are reading/writing to the machine throughout the day?
3) Do RAID 1 systems handle being accessed by different OSs (WinXP, Win7, OSX 10.4–10.6) well?
4) Am I right in thinking that OSX would see the two drives as separate volumes?
5) Should one drive fail and need to be 'rebuilt' via Disk Utility, can users still access the one working HD, or do you need to replace the failed HD and rebuild before anyone can access the data again?
6) Considering Question 4 above, do we need to have a 3rd 'spare' 1TB Drive just in case?
7) We are looking into a two-week backup system, backing up all the customers data on a daily basis, with the previous week's disk being stored off-site. We were initially looking into either Carbon Copy Cloner or RSync the copy data to external HDDs. How would you rate Time Machine against these products, and does anyone have any experience using these solutions with RAIDed Macs?
8) Is there any 'downside' to RAID 1 systems?
I know this is a lot of questions, but I really don't want to start down this route unless I understand it better first.
Many thanks in advance for your contributions!

Thanks for your reply!
So, in order to have a RAID visible and accessible by multiple OSs, and to eliminate downtime during rebuilds, a hardware RAID would be necessary.
Well, not quite. When you create a RAID in Disk Utility, the volume only exists as a MacOS X file system. Your Mac can share that volume to any other machines or operating systems.
What I mean by a hardware RAID is some box whose output port is eSATA or USB or some other non-network storage port. On such a device, the logic to create the file system is inside the box. Any machine that is connected to it would see only a single disk. You would still have to ensure that different operating systems could understand whatever file system you were using (HFS+, FAT, NTFS, etc), but that is the same as if you had a non-RAID external drive.
I have one of those. It is an older FireWire 800 drive that has two 300 GB disks inside. To any machine I connect that to, it appears as a single 600 GB drive. This particular device isn't designed for mirroring, however. If it were, it would only show itself as a 300 GB hard drive and I would have the capability to easily swap out the internal mechanisms when they fail.
By 'hardware RAID', do you mean inserting a RAID controller card inside the G5, or a separate storage device, such as a RAIDed NAS-type-thing? Would an ethernet-connected NAS be slower to access than a G5 with internal SATA? Am I right in thinking that those RAID-ready NAS devices cannot be partitioned at all?
I qualified the above to explicity avoid NAS devices just to simplify things.
I'm not familiar with RAID controller cards. My guess is that they are just a cheaper alternative to an external RAID device. It would allow you to plug your own hard drives into the controller card and create the RAID. They would certainly provide higher performance that if the operating system were handling the details.
If you want to have a RAID for data reliablity, you really need an external, self-contained device that has a standard hardware storage port you could plug into any machine. It would look and act just like any other external hard drive. But if a drive failed, a light would flash on the box and you could just pull out the failed hard drive and replace it with a new one. You wouldn't even need to power anything down.
For both RAID controller cards and stand-alone boxes, you may or may not need additional software to partition and format the drive. It depends on the model and manufacturer.
Such a device could also be NAS. In this case, it would have an ethernet interface instead (or in addition). The difference is that such an interface would almost always be slower than a true storage interface like Firewire or USB. Plus, you would usually have to let the box itself handle its partitioning and formatting. Since it is designed to be a networked drive, you don't need another machine to be the server. It is its own server. This is useful in those cases where you don't want/need a dedicated server. The downside is that it probably runs some lowest-common denominator Windows networking for maximum compatibility. Foreign, networked filesystems are always going to be more flaky. Some software may not work. Some OS upgrade may give you hassles.
To be honest, I'm no expert on RAIDs. In such situations, I usually just defer to people I know are experts. So, just buy the amount one of these: (http://eshop.macsales.com/shop/hard-drives/RAID/Desktop/), plug it in, and go. I suggest RAID 5.

Problem with some queries after migration from MS Access

Hi everyone!
We've just finished a migration from a MS Access database and we notice some errors when running some queries like :
Query1:
SELECT A.field1, A.field2, B.field1 as FieldTmp
FROM A,B
where (B.field1 <=10);
Query2:
SELECT Query1.field1, Query1.field2, Query1.FieldTmp
FROM Query1 LEFT JOIN Table3
ON (Table3.field1 = Query1.Field2) AND
(Table3.field5 = Query1.FieldTmp)
WHERE ((Table3.field5) Is Null)
ORDER BY Query1.field1, Query1.FieldTmp;
The Query1 runs as expected, but when I try to run the Query2 I got a ORA-00904 error message. If I remove the (Table3.field5 = Query1.FieldTmp) statement or modify to compare with another field (as instance, field2) everything goes fine.
If I modify the first query to a make-table query, the Query2 request runs as desired too.
Is there anything that we can do to keep the queries statement as it is when using the MS Access DB?
Thanks in advance,
Elaine Viel Denadai

Hi Turloch! Thanks for your help!
Those SQL Statements were extracted from the MS Access application that we will continue to use to access the data , now on an Oracle Database.
I don't know what I can do to make this kind of statements works as it is on Access database. The first query, that I called Query1 works fine on Oracle, I just mentioned it because the 2nd Query , named Query2, use it.
I'm not able to understand why when I change the 1st. query to a "make-table" query the Query2 works as desired, but if I keep the Query1 and Query2 as it is on the MS Access Application I got the ODBC error message and the ORA-00904 error message , related (I think!) to the FieldTmp field used on the LEFT JOIN statement (AND).
As I told before, if I change the AND clause to compare to another field, as instance, field1 :
FROM Query1 LEFT JOIN Table3
ON (Table3.field1=Query1.Field2) AND
(Table3.field5 = Query1.Field1)
it works.
Please, is there anything that I can do to keep the MS Access Application unchanged?
Oracle = 8.1.6
Oracle ODBC Driver = 8.1.6.4
Oracle Migration Workbench = 1.3.1
Thanks in advance,

I have some queries related to Nexus .

I have some queries regarding Nexus Architecture.
1) We have MSFC and PFC for layer 3 & layer 2 communication in 6500 .
How layer 2 & 3 traffic is been handled in Nexus. Do they have a specific asics. What are those asics ?
2) We have three types of line cards in 6500. Classic /fabric enables/fabric only.
Are all line cards in Nexuas are facbric only. What is the Asic which we use for distributed forwarding in line cards in Nexus as we use DFC in 6500.
Fabric modules in line cards are used for providing wire speed or it has other benefits as well. can i say it is just a kind of constellation bus which we had in 6500.
3) Are there and D bus/R Bus / EOBC on Nexus.
I believ D- bus wont be there as it use fabric. What about the results. Does it use the same LTL index logic to calculate result. I believe it should as it is from same family as it is known as EARL 8.
How does it handle control plane traffic / data and result .
Lets say I have a machine A connected to Module 2 port 1 ( M1 card) and machine B connected to module 3 port 1 on same chassis(7018) .
What will be the whole process which it will follow. Let say layer 2 traffic will be handles by Superman and layer 3 will be handles by Tycho.
if any one can explain me the whole packet flow that would be great.
4) What is the role of Supervisor in Nexus. It has central Arbitar Asic which id some thing diffrent then 6500. VOQ is also handled here. Can we say if we use central Arbitar Asic on line cards ...They will start working as supervisor some what .
Any comments will be appreciated.
Thanks
Namish
3)

1- Nexus used distributed architecture and all the line cards support L3 except the F1 which you need to mix it with M series to get L3 functionality
2- nexus has diffrnet architecure form 65K however new line cards can provide you line speed 10G per port such as F2
3- Nexus uses fabric modules with full mesh channels between these modules and each line card ( provide you much more capacity than 65K for sure )
for packet flow you can find it on cisco.com because it long a bit however in brief:
- Unicast Forwarding Distribution Manager (UFDM) interfaces
between URIBs on supervisor and IP FIB on
I/O modules
- IP FIB process programs forwarding engine hardware on I/Omodules
4- the Unicast Forwarding Distribution Manager and L2 forwarding manager are examples of what is hosted in the SUP
hope this help

Some queries in XI...

Hi XI guru's,
I have some queries in XI, can you please clarify the same. and the queries are:
1. Is there any special reason for HTTP placed on ABAP stack rather that J2EE stack?
2. How to monitor pipe line services ? Is there any dedicated Tx code for that?
3. Whenever we get exception like ALE services are not available?
Kindly clarify above queries asap.
Cheers.,

Need to create some queries.

Hi,
I am having some issues with creating some queries with respect to some information that is needed.
1) How can i get the list of tables from my schema that have not been used for some time (for e.g for the past 2 months no dml activity has happnd)?
2) How can i get the information of those users in a instance who have direct access to the tables in my schema.?
Thanks,

Hi,
Thanks for that
But i would like to know one more thing.
DDL_TIME will show only any ddl statement issued against that.
What if we are still accessing the tables using select statements ??Well a select statement isn't, strictly speaking, even a DML statement as it is not modifying the data.
There is no automatic recording of time when DML or select statements are executed against tables. With DML you can choose to record that information yourself through your own table design and code. If you have control over the application front end you can record when queries are made, but you can't automatically record when someone queries a table just using a select statement directly on the database (at least not easily)
You can also delve into the archive logs to find DML times but they are not guaranteed to be held for as long as you will require and certainly won't be there two months later.
Essentially, you can't determine information that you haven't chosen to store.

Object changeability: why are some queries now unmodifiable..?

Hi Experts
I recently had BASIS open our BW Production client so I could activate a cube that had been deactivated after a transport to BWP. Then BASIS closed the client (setting = unmodifiable).
After this, some queries in Production are now not available for change. We get this message:
Diagnosis
You want to change objects although the system setting is "Not Changeable".
System Response
The objects cannot be changed.
Procedure
Change the setting for the system or client to "changeable". You can do this using transaction SE06 or SCC4.
For some reason this only occurs for some queries, not all. Some are OK to change, just as they were before.
The client settings are unchanged. I have checked the object changeability options in the Transport Connection - just about everything is set to Everything Changeable or Changeable Original.
Why have some of our queries suddenly become non-changeable??
Points will be given of course for any advice. Thanks in advance
tony

Gents
Thanks for your replies. Unfortunately, none of these suggestions made any difference to the problem although they were good things to check.
It turned out that there was role that had changed, and the cause of the problem was simple authority. The message about the client needing to be opened was a Red Herring..
Bad messaging on SAP's part.
Once again, thanks for your help.

PC user wanting to swap to Mac has some queries.

Hi,
As the title suggests I have a few queries about swapping from PC to Mac. Firstly I've been informed that you can't directly compare speeds, processors, RAM etc of a PC with a Mac as MAcs run quicker, but is there a way of knowing what an equivalent mac is compared with a specific spec PC. I understand PC specs but not sure how they translate to Mac. For example, my current Laptop has Intel Core 2 Duo 2.13GHz processor with 4GB RAM (I'm wanting to improve on this spec), what would the equivalent Mac be?
I use my laptop for Full HD video editing and use Sony Vegas Movie Studio Platinum 9, and have found out this is not compatible with Mac. The only equivalent software I've seen for Mac is Final Cut Pro X, but I'm not prepared to pay £199 for this, especially considering the fact you can get Sony Vegas..... Platinum 11 for £30. Therefore I would need to partition my Macbook and run windows 7 (unless someone can recommend a good video editor for Mac which is much cheaper). Is it free to install windows 7 on a Mac or do you have to buy software? If so how much is it? Would it still recognise AVCHD?
One issue I have with Sony vegas on my current laptop is that it takes ages to render HD video, it can take hours (literally) to render 10mins of video. I don't know if this is down to the OS, RAM, processor or Hard drive, or something else. When editing I only have this one program open as using any other program (even the internet) is painfully slow. Would having a quad core i7 processor and 8GB RAM speed up the rendering process? Do Macs speed this process up, or if you are running it in windows mode would it be exactly the same as running it on a PC?
When ripping music to the Mac can you only rip in AAC/ALAC or can you rip it as MP3 so it's more 'universal'? I have music systems that can't read AAC :-/
Finally, when having a quick 'play' with a MacBook in store (PC world) I noticed that when I opened new Windows/apps the window did not fill the entire screen, and when you opened up further windows/apps you could see them stacked over each other a bit randomly. Can you change the setting so that the windows fill the entire screen, and can you set it so that this happens as default?
Sorry for all the questions, but I want to make sure a Mac's right for me before forking out thousands of pounds.

Yes, the OP should buy whatever they want, Mac or PC.
However, the OP has come here to ask Mac questions.
A Dell Latitude is not a notebook for video editing, and it is not supported as such by any of the major software developers.
You would need a Dell Precision for editing.
A Mac will run Windows far better and faster than any Dell for the simple reason that Windows on a Mac is a clean, no crapware installation. Any Dell comes with several pounds of bloatware.
If you want a Kia, buy a Dell. If you want a Mercedes-Benz, buy a Mac.
This is not a fanboy opinion, but an easily verifiable fact by reading computer reviews and sales figures.
Good luck!
Physically, a MacBook Pro will last longer because it is made of durable anodized aluminum versus cheap cracking plastic on PCs.
PC companies make almost no money on notebooks. It is clear that they cut corners.
Add AppleCare, and there is just no credible comparison.
I digress from the OP's questions, but the nonsense of some needed to be addressed.
Ok lets addrees some of this.
But First Thank you fane_J. A voice of reason.
A Dell Latitude can have as good video card as a Dell Precisions. And if I wanted I could change the video card I ordered with my Latitude to any that is available for that model at time of production.
A Mac comes with either Video card A or B and can NEVER be changed. Even if it goes bad the only way to change it is to Replace the complete motherboard which includes both the CPU and GPU. They are Soldered onto the Motherbaord. Nor can you ever upgrade the CPU because it is Soldered onto the board. You can on a Dell notebook.
Have you ever heard that you can format any hard drive on any computer and install the OS clean without the makers included FREE (read that KWrap) software? Well you can. And I am sorry but Mac's also come with K_Wrap ware. Photobooth? iChat? and especially iTunes. And some of the Mac software you can't uininstall.
The reason a Mac will run Windows is because they Use the Same Hardware. Better then a dedicated Windows PC? No I am afraid not for one simple reason. You can not wipe the drive of a Mac and install Only Windows. You first have to install OS X then partition the drive and install Windows. You HAVE TO USE Apple supplied software to access some of the hardware included in a Mac. Also you can only have that One partition for Windows. Try to make a second partition and you break both Windows and OS X.
My Dell Latitude is ALL Metal. Not one plastic piece to the case. If you ever looked inside a MBP you would see many plastic pieces.
No PC makers make money on notebooks, just where did you get that. Notebooks are not Printers where the manufacturer makes money on the Ink they sell.
My Dell came with a 3 year warranty, mail in, included with the original cost. And I could of gotten Accidental Damage Next Business Day On Site service for somewhere around and extra $200. Dell Complete Care Warranty.
That is far less then I paid for the Applecare warranty for my MBP and I can't get Accidental Damage or On Site Service for a Mac.
No credible comparison, Again just where do you get that. With the Dell I don't have to Make an Appointment to have it looked at and then be told it isn't covered.
An YES some this nonsense had to be Addressed.
Which is not digressing from the OPs question.
Thank you.

Some queries on Data Guard design

Hi, I have some basic questions around Data Guard design
Q1. Looking at the Oracle instructions for creating a logical standby, it firstly advocates creating a physical standby and then converting it to a logical standby. However I thought a logical standby could have a completely different physical structure from the primary. How can this be the case if a logical standby first starts its life as a physical standby ( where structure needs to be identical ) ?
Q2. Is it normal practice to backup your standby database as well – if so why ?
Q3. Can RMAN backup a Standby Database whilst it is in the mounted state ( rather than open ) ?
Q4. What's the point of Cascaded Redo Apply rather than simply getting the Primary to ship to each Standby ?
I guess you could be trying to reduce node to node latency if some of the standby were quite distant from the primary
Q5. Is it possible to convert a Logical Standby back to a Physical one ?
Q6. What the maximium number of standbys you can have - Oracle suggests 30 but I thought I remember reading somewhere in relation to 11gR2 that this limit has now been increased ?
thanks,
Jim

Q2 . . Is it normal practice to backup your standby database as well – if so why ?
Hence you only have to backup one of the both (you can decide to only backup the standby though, if you want to remove load on the primary). But if you are confident with the backup of the primary, there is no need for backing up the standby. (Since you can recreate the standby with the backup from primary).

Woodstock 4.1.1 some queries

Hi,
I am using Woodstock 4.1.1 JSF Components in my application.
In my application, I have used the
<webuijsf:form name="addRemoveForm">
<webuijsf:addRemove> </ webuijsf:addRemove>
</webuijsf:form>
I have mainly two requirements:
1. In the list box there is some blank space taking up the space after the list item. How do I get rid of that extra space in the list?
2. In the vertical layout, how can I have the remove button below the "Selected" list box. Basically can we alter the position of the add/remove buttons?
Please let me know some pointers on this.
Thanks in advance
MK

Never mind/No problem - this problem was related to the procedure for using nightly sdks (rename player dir and remove {targetPlayerMinorVersion}).
While attempting to troubleshoot some errors after upgrading sdks from 4.0 to 4.1 - I lost track of my brain.

Thinking of buying Vision M to replace Zen Micro...have some queries on internal batte

After?wearing my 2-year-old zen micro into the ground, I've decided I want a Vision M. With my old micro, I'd?got through two batteries and was well on my way to a third - the battery just wasn't lasting long e nough?anymore. With the removable battery, I just replaced it, but I'm worried as to what will happen if I buy a Vision M. If the battery gets to the stage when it only lasts about 3-5 hours of play time, what would I do? I don't know if integrated batteries are more substancial than removable ones...if someone could let me know about this that'd be great. Thanks?in advance?=)

I had this same question and did some searching. I found the following site;http://www.anythingbutipod.com/archi'ves/2006/02/how-to-disassemble-the-creative-zen-vision-m.phpI'm guessing this would void the waranty, but I'm also guessing that by the time this was required the waranty wouldn't be a issue anymore anyway.

Vendor Registration -- some queries

Hi,
We are using the vendor registration component ( ROS) and after the new registered vendors has become a business partner in SRM (EBP) ,
1. We want a process to capture the continuous update of vendor data. How this could be done in the SRM ( Either through
ROS/SUS/SRM?) ?. we need a 2 step work-flow, after the vendor has updated the data, to accept the changes done by the
vendor.
2. Also, we want to capture additional details like TAX ID and Bank details , only for the approved vendors and the vendors need to provide this data online ( changes to existing data) and this should go through a 2 step work flow for the changes to be approved.
Pl provide your inputs.
Thanks and Regards

Hi,
Its not transacton code..
HRMD_ABA is the message type used to transfer HR master data ( organiztion,position, user ) from
backend R/3 system to SRM system.
Need to configure ALE/IDOC in the SRM system. Using PFAL Transaction can do the initial transfer of data.

Creating a Live CD....some queries

Hello!
I'm trying to create a Live CD from my current Arch installation. I'm not using any of the 'automated' scripts (like Larch, makeliveiso or even those from linux-live.com), but trying to do it the 'hard way', i.e. right from scratch! I'v got a query regarding the linuxrc script in the initial ramdisk image.
How can I add auto-detection of CD drive to the linuxrc script? Currently, I've simply added 'mount -t iso9660 /dev/hdc /cdrom' since I know my cd drive is located at /dev/hdc, and it works ok. However, for different system, I must have a CDROM detection ability!
Any help and suggestion will be greatly appreciated.

You'll need to modify /etc/rc.sysinit to work as a live CD, that's where all the initial mounts are done.
s26c.sayan wrote:and Gradgrind, is there any way I can use your larch scripts to generate a live cd from a already installed arch linux system (like in the linux-live scripts)?
In principle, yes. Your installed system needs the following packages: squashfs-tools, initcpio_larch, cdrkit, dvd+rw-tools. You will also need a 'profile' (see the docs), but the 'addedpacks' and 'locale.gen' part is not needed. I can't remember at the moment how to change the name of the directory containing the installation ('ArchImage'), but you can change the build path in 'config_larch'. You could always use a symlink from 'ArchImage' to your root partition. Then you can build an iso using the -b option to mklarch. Of course you can't do this while you are running the system to be made 'live' - you need to use a system on another partition, or a live CD (warning for live CD - lots of space needed, use a large swap partition, or build on a different hd partition).
As you can see, larch wasn't really designed for this, it wasn't important to me, and I think linux-live does a pretty good job of this sort of thing. I believe archie can also do this, and a new release of that should be available soon.
I'm afraid I'm away for a while now, so if you need anything else from me, it will have to wait a few weeks.
Good luck!

Some queries on RAC database 11g

We have RAC oracle database 11g and we don't want to overburden the OLTP instance. So we thought of bringing the changed data from the OLTP instance to reporting instance via logical standby or streams and log the changes with the help of using total recall feature in the reporting instance.
Our idea is to retain the historical data using the total recall feature in reporting instance and bring the changed data from the OLTP instance to reporting instance via logical standby or streams
RAC database: OLTP instance ---> mine the changed data via logical standby or streams ---reporting instance (track all the changes made to a transaction using total recall feature in this instance)
My doubts are:-
1) Whether the total recall feature will work with work with logical standby database or streams?
2) How to transport the total recall feature enabled tables from one database to another. Whether the data pump will work with flashback enabled tables?
3) How to capture the changes from one instance to another with oracle streams. I could not find much documentation on how the streams work on RAC database. Any pointer /suggestion on this would be much appreciated.
Regards,
Richard

1)     Easy backup and recovery for a specific instance in case of historical dataWhat data will that be? If this is a 3rd RAC instance, then it will not make backup easier as the data is in the database (on shared storage media) and that needs to be backed up - the database's data does not reside locally on the instance.
2)     Point-in-time recovery is possibleAgain, I do not see how this is a specific advantage that now suddenly occurs with the introduction of a 3rd RAC instance.
3)     If any other node fails, then it won’t affect this instance Correct - a 3rd instance increases the redundancy in the cluster. It also scales it and provides additional processing capacity.
