Can dynamic in-memory queues be created programmatically in OC4J?

Is it possible for an EJB to dynamically create an in-memory queue in OC4J?
I'm using message-driven bean for concurrency. That is, each client posts messages to a queue so that message-driven beans can process each message concurrently. Each client will receive responses from the MDB's via a response queue. I want each client to dynamically create its own in-memory response-queue. Thus, is it possible to dynamically create an in-memory queue in OC4J? Or is the only option to have a single queue, or pool of queues, and use a message selector system for each client to identify its response messages?
Thanks,
Travis

Can I add Custom Content Type created programmatically to Custom List Definition?

I have created Custom content type programmatically in the Feature Receiver. Followed by this have another feature which creates List Template. I want to add the custom content type to the list template.
Using VS 2012, I added the custom content type to the list definition. The Schema.xml for the list definition looks as below:
<ContentTypes>
<ContentTypeRef ID="0x010100D7D9F4B1F4A9684BB44389571024B2EC00C393BB21B8AD7B41B62A87DF0501504D" />
</ContentTypes>
ID was automatically added by the VS tool.
List Template is created, the new content Type is also added, but the Name is displayed as "Document" instead of the custom content type name. So I see two CTs with the name "Document".
How can I achieve this? Any help is appreciated.

Hi,
Please add EnableContentTypes="TRUE" in the <List > tag.

FTP Adapter internal in-memory queue

Hi,
I am trying to implement the use case where i need to pool the new files from the FTP Server. We have only read access to FTP Server. So we can't archeive or delete the files from the FTP Server. And when the new files are placed in the ftp server we need to process only the new files not the old files.
When i have read the file adapter documentation, the default thread will poll the meta data info of the file and store in internal in-memory queue, processor will pick only new files based on the meta data information available in internal in-memory queue.
Can any one please let me know where exactly the internal in-memory queue is stored because as part of system maintenance we need to perform purging or backup the soainfra schema. If i perform purging on soa-infra still the file metadata stored in in-memory queue will exists so that old files are not read again?
Regards,
Manohar

The solution is either change the order of deployment or copy the FileAdapter.rar file in $ORACLE_HOME/lib location and restart the server as mentioned here.

Is there a way to dynamically allocate memory in labview?

In the C programming language, there are malloc() and free() functions which, combined with pointers, allow the user application to dynamically allocate memory.

LabVIEW does all of its memory management completely automatically, which is almost always an extermely good thing, and you don't have any real way of controlling it. Normally, memory is reused throughout the application and deallocated when the top level VI is closed. You can use the deallocate VI (in the Advanced pallete) to force a deallocation, but this will only help if you finished with the subVI.
The new version 8.0 also includes an option to decide when a subVI will be loaded into memory, which can also help. Normally, real memory problems in LV only occur when you have very large structures because LV needs a contiguous block of memory to hold its data. For most cases, there are various solutions available.
Do you have any specific problems?
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

In my server RMAN can't allocate memory to the virtual instance

Hi
I want to restore my database in a new server
At first I want to restore "spfile" from controlfile autobackup, there is no spfile or pfile of my database in the new server
I do these steps
1 . expoer ORACLE_SID=Sales
2. rman target /
3. rman > set dbid 817528985
4. rman > startup force nomount
after step 4 I get this error :

I get this error while I have about *80GB* free memory on the new server
and my parameters in /etc/sysctl.conf file is :
kernel.sysrq = 0
kernel.core_uses_pid = 1
kernel.shmall = 5242880
kernel.shmmax = 42949672960

net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
I need to say that I can create a new database in that server by dbca that its
sga_max_size is 9632M and pga_aggregate_target is 3206M
Do you know what is wrong ? Do you know why RMAN can't allocate memory to the virtual instance ?
thanks

The database which could not start is because of the low memory on the system or in the sga_max_size there is high value set. So the system could not allocate so large memory as it does not have free so much. There may be other reasons like OS limitation in order of usage the memory.
Set a lower amount of memory in the database.
Eg:
SQL> alter system set sga_max_size=1600M scope=spfile;
System altered.
SQL> alter system set sga_target=1600M;
System altered.
refer the link it will be useful:http://arjudba.blogspot.com/2008/05/startup-fails-with-ora-27102-out-of.html
else use manually copy the spfile/pfile to the new server

Missing queues for created indexes

Hi,
I'm trying to enable the search function for e-recruitment.
TREX is installed and in the ERP 6 system, the customising to create the SSR has been performed, the document class to be indexed set up etc. and the settings have been checked in SKPR07.
Having set up the indexing, I can see that I now have three indexes in TREX, one for each client in my ERP 6 system. However, no queues have been created. Shouldn't the queue be created when the index is created? Any ideas?
At the moment the system knows that there are documents to index but can't since I'm assuming there is no queue.
In addition, when in SKPR07, a message is displayed saying that documents are to be indexed using the new API, SKPR_INDEXING1. I've not found any help on this and that doesn't seem to work either.
Any ideas welcome.
Regards,
Rob Forster

Hi,
Thanks but I've resolved the issue now. We didn't have any queues at first to be able to flush but it was matter of turning on a parameter to use a queue server.
There was a pre-processor authorisations problem too.
Note 658052 and 650521 sorted us as far as indexing documents.
Now onto why the searches through the portal return 0 hits whilst they work in the backend. Still, a few more notes about that.

When Broker Restarts None of the Temporary Queues Are Created

Somehow when the broker restarts none of the temporary queues are getting recreated. The queues were created successfully the 1st time and the applications were happily exchanging messages. Things just fall apart when the broker restarts.
I'm able to reproduce this problem consistently by doing the following:
1. Start imqbrokerd (mq start)
2. Start client application
3. Shutdown imbrokerd (mq stop)
4. Start imqbrokerd (mq start)
After the producers in the client application have reconnected the following messages are displayed in the console. I'm only able to get the client app to work again is if I restart the client apps.

I also tried versions 4.4 and 4.2 and received the same behavior :(

The application is inside an app server but we're not using a resource adapter as we're using Spring and Camel to hide the JMS details. Spring (JMSComponent) manages the connection directly. (We current don't have any JMS connection pooling as well.)
<bean id="jmsTransactionManager" class="org.springframework.jms.connection.JmsTransactionManager">
<property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>
<bean id="jmsConnectionFactory" class="com.norvax.framework.jms.OpenMQConnectionFactory">
<property name="openmqBrokerConfiguration">
<props>
<prop key="imqBrokerHostName">$remoting{openmq.hostName}</prop>
<prop key="imqBrokerHostPort">$remoting{openmq.hostPort}</prop>
<prop key="imqReconnect">true</prop>
</props>
</property>
</bean>
<bean id="jms" class="org.apache.camel.component.jms.JmsComponent">
<property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>
I'm going to write a very basic producer using Spring without using Camel and see if I'll get the same behavior. I'd like to see if the way Camel uses JMS is what's making OpenMQ broker to deny creation of temporary queues.
Thanks,
Jeff

How can I reclaim memory/storage so I can burn a DVD with iDVD?

How can I reclaim memory/storage so I can burn a DVD with iDVD?

Move your iPhoto Library and/or your iTunes library to and external HD that is formatted OS X Extended (journaled) and run them from there. Be sure to try the libraries on the EHD before you delete them from the boot drive.
This should easily free up the 25 GB minimum needed for iDVD to create and burn video DVD efficiently.
Follow this workflow to help assure the best qualty video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

can any body suggest me how to create match code object and match code id..

to avoid confusion in selecting the values.
i need only selcted values..
thanks in advance.
vijay chavan

Hi
In Older SAP versions Match codes are used, now they are replaced by SEARCH HELPs
there 2 types of search helps
Elementary and Collective
see the doc and create accordingly
1) Elementary search helps describe a search path. The elementary search help must define where the data of the hit list should be read from (selection method), how the exchange of values between the screen template and selection method is implemented (interface of the search help) and how the online input help should be defined (online behavior of the search help).
2) Collective search helps combine several elementary search helps. A collective search help thus can offer several alternative search paths.
3)An elementary search help defines the standard flow of an input help.
4) A collective search help combines several elementary search helps. The user can thus choose one of several alternative search paths with a collective search help.
5)A collective search help comprises several elementary search helps. It combines all the search paths that are meaningful for a field.
6)Both elementary search helps and other search helps can be included in a collective search help. If other collective search helps are contained in a collective search help, they are expanded to the level of the elementary search helps when the input help is called.
CREATION:
Go to SE11 Tcode
select search help
give the 'z' search help name and create
select the selection method ur table name eg : 'mara'
dialog module 'display value immediately'.
add the field whatever u want and lpos = 1 and spos = 1 and check import and export parameter.
where left position when displaying and spos = search position
and then save and activate ..

Collective search help Combine several elementary search helps. A collective search help thus can offer several alternative search paths.
A Collective search help provides alternative search
Paths by combining elementary search helps.
Only one search help can be attached to a field, table or data element. Several search paths are therefore attached with a collective search help.
A collective search help also has interface parameters like
an elementary search help.
Like an elementary search help, a collective search help has an interface of IMPORT and EXPORT parameters with which the search help exchanges data. Using this interface, the collective search help can be attached to fields, tables and data elements exactly like an elementary search help.
Parameter assignment needs to be done for each of the
Included search helps.
When you define a collective search help, there are no components for describing the dialog behavior and data selection; instead the included search helps are listed here. You must assign the parameters of the collective search help to the interface parameters of the included search help for each inclusion.
User may choose the tab and thus the elementary
search maethod.
When we execute the search help SCUSTOM, we are confronted with a dialog which gives us an option of either restricting
By 1)Search for customer according to booking
2)Search for customer according to name.
These are effectively the elementary search helps (SCUSTOM_BOOK and SCUSTOM_NAME) which have been included in the collective search help SCUSTOM.
HOT KEY
The hot key is used to select the elementary search help from the collective search help and to enter the restrictions in the dialog box for restricting values directly from the entry field. If the user often searches for values using the same search help, this procedure can save time.
Steps to create a Collective Search Help
1)Enter the search help name and click on create.
2)Choose Collective search help radio button option as the search help type.
3)Enter the search help parameters.
4)Instead of the selection method, we enter the included
search helps for the collective search help.
5)We need to assign parameters for each of the included
search helps.
6)Complete the parameter assignment by clicking on the push button
7)Collective search help offers the user to obtain F4 help
using any of the included search helps.

Not able to memory dump and create a memory.dmp file in the path: %SystemRoot%\Minidump

This question is a part of my job profile. I work for an MNC chip maker. As a part of our systems testing environment, we boot into the Microsoft windows 8.1 windows OS and run some specific tests from the OS. The platform design (mother board) is an internal
design.
Issue is with the booting sequence since no much information is available when Windows 8.1 tries to boot and when we see the splash screen. Especially when we see a BSOD, there had been no leads.
I tried to enable the small memory dump option in Windows 8.1 OS which tries to write the files into the location %SystemRoot%\Minidump on a system crash while boot. Please note that Windows 8.1 has been stored as a .VHD file in the hard disk (which
is the boot-disk). The issue is, even in an event of a BSOD while booting, I am not able to see any memory dump files that had been logged in that location.
Is this issue would have been caused by the VHD file format since it is a virtualized disk ? Please let me know what all the issues could be, so that I can have some memory logs here to look into. May be analyze the Windows debugger.
Best Regards
Akhil

Hi,
The causes why Windows does not save memory dump file after a crash are listed in the link below:

I suggest you check the space, make sure that there's enough room for the memory dump file.

Shared Memory Service Not Created Yet

Hi Everyone,
I had to get a new printer because the baby did something to my old one and now it won't print clearly. I got an HP Officejet 4315 because it was the only one that said it supported 10.2.8. When I installed the software, I got a message saying, "Driver Not Installed." I checked the HP website, and they said to install the BSD from my CD's, which I did, now when I click on "HD Assistant" I get a message saying, "Shared Memory Service Not Created Yet."
I can't find anything on the HP or Mac websites about this error message. I e-mailed HP Support, they said to repair permissions and re-boot, which I did, but I still get that error message.
Please don't tell me to buy a new computer so I can get a new OS, because that's not financially feasible at the moment, since I'm a stay-at-home mom.

You're Welcome Lizzy!
Upgrading your Mac to Panther 10.3.x would be quite painless, and depending on whether it meets the Panther System Requirements, and the Additional Panther System Requirements, also relatively inexpensive.
If you know what to look for, a Full Retail Version, of the Panther Install CDs, can also be purchased rather inexpensively, at some additional online Apple retailers, Amazon, eBay, FastMac, etc.
Be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
Panther is only on CDs, not DVDs.
Unless purchased from AppleRescue, the discs should look exactly like the images in the above links, and not say Upgrade, or CPU Drop-in DVD, on them.
