RBO conversion
Dear all,
We are using 9.2.0.8 on solaris 10 with RBO.
Now we are planning to change to CBO . what are all the steps in doin the same.. am foccusing on the below steps :
Set optimzer_mode=ALL_ROWS
restart the database
collect the stats.. (db stats,schema stats, system stats)..
Am sure that there will be many.. As always,please guide
Kai
Please read Migrating to the Cost-Based Optimizer http://www.oracle.com/technology/products/bi/db/10g/pdf/twp_general_cbo_migration_10gr2_0405.pdf#3.
Although this document is for Oracle 10g many steps should apply to your case.

Hi,
I need some help.
My databases are running in RBO environment using oracle 8i, 9i. Now, because RBO being obsolete in oracle 10g and later releases. I want to switch to CBO.
My databases are in production. I want to look at all the scenarios for conversion to CBO (oracle 10g).
Could you please suggest, What will be the best approach for that, how should I start.
I want to know, what conversions are required for changing to CBO. How should i check the performance after conversion e.g. should i check the performance of all operations in both RBO and CBO environment or something else.
Almost all my queries are using hints, do I have to make some changes on queries also, if yes, then this might be the major task for me. Is there any other way out ?
If, any other information is required, please let me know.
Please help in determining the best strategy.
Regards
Ashish GoelWell, if the RBO is truly desupported in 10G I would expect the RULE hints to just be ignored.
Keep in mind that you will need to generate stats to assist the CBO so that might be step one (getting a stats gathering job in place).
As per Strategy, do you know what your most frequent and imporatnt queries are? If so, benchmark them and comapre in 10G with CBO. -
9i to 10g Migration, RBO to CBO conversion
Hi All,
We used to have 9.2.0.4.0 DB and our applications are tuned to RBO using 'rule' hints.
Recently we migrated to 10gR2 (setting optimizer_hint = 'FIRST_ROWS_1') and we expected that the applications that are using 'rule' hint will be ignored or atleast code will throw errors. But when we looked at the trace file, it looks like it is using RBO.
When Oracle say that RBO is not supported in 10g, does that mean we can still use RBO at our own risk ? Are there any other parameters that need to be set so that CBO is used though RULE hints are used ? (I don't think so..but just to confirm)
Please let me know if someone has any pointers on this,
Thanks,
madhu.The RBO is no longer supported by Oracle in 10g. The rule hint and optimizer mode are still present in 10g. You are free to use the Rule hint and optimizer mode in 10g, with no support from Oracle.

Conversion of Characteristic Values to SIDs is taking long time
Hi Experts,
Cube load is taking more than 7 hrs to complete for 6 million records. Max time is at Conversion of Characteristic Values to SIDs. Cube consists of 500 fields. Load is from DSO to Cube. DSO has 10 fileds with no SID flag check for activation. Remaining fields in the CUBE are pouplated looking in to other DSO's. Start and End routines are executing very fast. How to fasten Conversion of Characteristic Values to SIDs step. I need to load 15 million records daily as part of delta. any suggestions.
Thanks

11i to r12 Conversion - help needed
Hi
My client is doing re-implementation of r12 and migrating from 11i to r12. I need help particularly on conversions side. The client is a SaaS company. they are considering to bring open and history transactions and applied/unapplied receipts to r12 AR.
- how to migrate revenue scheduled open/closed invoices from 11i to r12 since rev schedules for a SaaS company is expected to be long terms. and how to make sure that rev schedules are correct upon migration to r12??
- for partially paid invoices how to make sure that the same partially paid amount reflects in r12 upon conversion? can a negative line amount equalling to paid amount be a possible solution??
- upon migration do the closed invoices have to be converted as open and receipts re-applied after migration in r12 or they can be brought in as-is with status closed?
- if customer paid for an invoice using a credit card in 11i and upon migration it came to notice that the credit card is no longer used by the customer so how to re-apply the same receipt in r12 which was applied in 11i using that credit card. do we have to enable it in r12 just for closing the invoice? what could be possibilities?
please anyone if can answer would be very helpful
Thanks
-MSIt depends on the dpi. Usually 72dpi = 72 pixels per inch.
1000/72 = 13,88888 inch
1 inch = 25,4 mm
13,88888 * 25,4 = 352,7777 mm
You do the arithmatic with a calculator.
To do the same with pictures, you can do it in any image editor. Even Preview.app :

iMessage beta looses all saved conversations when I open and close a window.
Just reporting this bug... Could not find anyother place to do it.
JonathanI thought it was doing that also. But I found that if I start a new chat with someone I was messaging before, then the old messages re-appear in the messages window.

Is there a way to selectively edit a conversation in iMessages instead of clearing the entire conversation? Like you can do on the iPhone for instance.
Did you find an answer to your question?
Would it also apply to Mountain Lion's Messages?

I need to delete myself from a Group Conversation.
My idiot friends added me to a group conversation and i cannot leave it. Each time i ask them to start a new conversation and not include me they refuse. My phone has been ringing non stop for 3 days now and i need to find a way to get out of this conversation so that i can go to class, do my homework and sleep at night!!! I can turn my phone onto Airplane mode but when it is in this mode I cant receive the important phone calls and text messages that i need to answer.

Hi. I often use the conversation search option when archiving my emails from inbox. I find this a very useful method of finding trails where I and multiple people have responded to each other. However If I have already moved one or more of these emails into the archive folder and select all to move, Thunderbird will not move any. I then need to individually select those that need to be moved.
Although not a major issue I use this regularly and often come across the problem. a recent fix which allows location tab to remain on in search helps but does not resolve this issue. A slightly annoying problem and I was wondering if any one else has this issue. Also is anyone looking into a solution?FCPx answer: At least the answer that worked for me...
I had the same problem, as I believe many others had.
In my case the problem was with one of OSX Mavericks' new features: APP NAP.
It looks like this is ON by DEFAULT for ALL Applications and that FCPx, or Compressor for that matter, will not work if this is enabled on them.
I just disabled App Napp on FCPx and now it works, again, like a charm.
This is how you disable App Nap: http://reviews.cnet.com/8301-13727_7-57612009-263/how-to-disable-app-nap-in-os-x -mavericks/

Import conversion data table from SAP R/3 into value mapping table in XI
Hi:
Somebody knows how to import a table with conversion data that are in SAP R/3 and to take it to a value mapping table in XI?
The purpose is to use a mapping table that can change in the future. Must I use a ABAP programming that retrieve data and build the value mapping table?
If so, how I specify in the ABAP programming the group id, the scheme, the agency and the corresponding value?
Please, help me.
Regards!!!Hi David,
please refer to this section in the help: http://help.sap.com/saphelp_nw04/helpdata/en/2a/9d2891cc976549a9ad9f81e9b8db25/content.htm
There is an interface for mass replication of mapping data. The steps you need to carry out to use this are:
+Activities
To implement a value-mapping replication scenario, proceed as follows:
1. Register the Java (inbound) proxies.
To do so, call the following URLs in the following order in your Internet browser:
¡ http://:/ProxyServer/register?ns=http://sap.com/xi/XI/System&interface=ValueMappingReplication&bean=localejbs/sap.com/com.sap.xi.services/ValueMappingApplication&method=valueMappingReplication (for the asynchronous replication scenario)
¡ http://:/ProxyServer/register?ns=http://sap.com/xi/XI/System&interface=ValueMappingReplicationSynchronous&bean=localejbs/sap.com/com.sap.xi.services/ValueMappingApplicationSynchronous&method=valueMappingReplicationSynchronous (for the synchronous replication scenario)
You only need to perform this step once (for each installation).
2. Application programming
The ABAP program must perform the following tasks:
¡ Read the value mapping data from the external table
¡ Call the outbound proxy used to transfer the data to a message, which is then sent to the Integration Server
3. Configuration of the replication scenario in the Integration Directory
This involves creating all the configuration objects you need to execute the scenario successfully. One special aspect of the value-mapping replication scenario is that the receiver is predefined (it must be on the Integration Server). The sender, however, is not predefined in the replication scenario and can be defined to meet your individual requirements.
For example, you can use the shipped ABAP proxies.
In the case of the receiver communication channel, choose the adapter type XI. Ensure that you configure a channel for the Java proxy receiver in this case.
Enter the path prefix /MessagingSystem/receive/JPR/XI for this purpose.

There used to be a preference setting in Pages. Now it seems gone in Pages 5. So how do I stop automatic conversation of URLs to hyperlinks and seeing them underlined in text. Sometimes I want it, but not always.
The preference setting to turn off links is gone. When you enter content that triggers link detection, a link character style gets applied. Right-click on the link, choose Edit Link from the menu, and then Remove.
To prevent Pages from automatically detecting links, visit Edit > Substitutions > and deselect Smart Links. -
Content conversion in sender file adapter problem
Hello,
I receive a flat file with the following structure:
HEADER;...fields;
ITEM;...fields;
ITEM;...fields...;
HEADER;...fields;
ITEM;...fields...;
...etc.
and I am converting it to xml with the same structure. The Problem by the conversion is that the result looks something like this:
HEADER;...fields;
ITEM;...fields;
ITEM;...fields;
ITEM;...fields;
HEADER;...fields
HEADER;...fields.
So, all the ITEM recordsets are ordered to one HEADER structure and the other HEADER structures have no ITEMs.
Do you have a suggestion how I can get this right?
Thanks!!
Best Regards,
MirceaHi,
Can you provide with the details of FCC parameters you have used ??

My issue is, How do I set my parameter in Sender Comm channel for content conversion especially at record structure.
I have provided the value as Header,1,Content,*
But its not working.
If I do provide like
BGN_REC,,REF_REC,,DTP_REC,,N1_REC,,INS_REC,,NM1_REC,,PER_REC,,N3_REC,,N4_REC,,DMG_REC,,HD_REC,* then ,I am not getting above XML format. Please suggest or How can I modify my Data type which competes to configure in Channel

J2SE adapter PI 7.1 issue with XML to flat conversion and namespace length
Dear reader,
We are facing an issue with J2SE Adapter PI7.1 for a number of flows.
The flow requirements:
[1] Namespace length for interfaces is up to 100 characters
[2] The XML message must be converted to Flat on the adapter channel
Our PI system is at patch level 7 and we implement J2SE adapter on patch level 7 as well.
We found that the J2SE adapter on patch level 7 does not support long namespaces [1] (as it should since this is an PI 7.1 j2SE adapter) but no issues where found with the XML to flat conversion [2].
Experimenting with J2SE adapter on patch level 6 we found the long namespaces [1] are supported however an issue is found with the XML to flat conversion [2] as stated in SAP note 1335527.
An SAP Customer Message is raised on this issue however your input is highly appricated!
With Kind Regards,
Harald Kastelijn

I think the restriction of namespace length still remains in design time (IR).....the same however has been extended in configuration and runtime...this SAP note has some information: https://service.sap.com/sap/support/notes/870809 -
In PDF to Excel conversion dates like 03/12/15 convert to Dec 3rd 2015 not the correct date of Mar 12th 2015 whereas date 03/13/2015 converts correctly as March 13th 2015
Hi DirTech,
Are both of these dates in the same Excel file? If they're in different files, are you choosing the same language for OCR (optical character recognition)?
If they are in the same PDF file, how was that PDF file created? Was it created from a third-party application (rather than an Adobe application)? If it was created by a third-party application, it could be that it wasn't written to spec, and that's why you're seeing some oddities in the PDF > Excel conversion. (See Will Adobe ExportPDF convert both text and form... | Adobe Community.)
Best,
Sara
