Increasing the number of thread results in core dump

Hi all ,
I am having application in C++ on Solaris and WIn NT OS . In Win Nt if the Number of Threads Spawned is 50 it's working fine but if we try the same it results in Core , but if we reduce the number of Threads spawned to 40 the application works just fine . The System configuration for WIn NT is 512 RAM and for Solaris is 1GB . Any pointers to what can be the possible reason and solution to the cause .

Hi,
The basis sets the maximum number of pages that can be printed by the user in authorization object S_SPO_PAGE.
Please discuss with your basis guy.

Do you know how to increase the number?
What is the number in a Production System?
Thank you!

It's under Service->http.
Use config tool for NW70.
For NW71 and above use NWA and config tool.

Increasing the Number of Candidate Job Search Results in E-Recruiting

Hello,
Would anyone happen to know where to go to increase the number of candidate candidate job search results in E-Recruiting? It's default value is set as only allowing 10 jobs per page. If you want to display more you have to click the down arrow. How would I allow it to show, say 25, or maybe 50 per page?
Any help you can provide would be appreciated!
Thanks Ryan!

Thank you Sandra for your reply,
I tried the following combinations in table T77RCF_UI_PARAM
Name                           Param.type                            Parameters
hrrcf_unrg_srch             MAX_VISIBLE_ITEMS             25
hrrcf_unrg_srch             VISIBLE_ROWS                     25
hrrcf_unrg_srch             SEARCH_POSTINGS             25
None of which increased the number of hits that appeared on the page. The value still remained at 10 per page.
It would appear that somewhere in the result_list.bsp view for hrrcf_unrg_srch that this is being set. If I view the methods for class CL_HRRCF_UNRG_SRCH_HL_RESULT_V I find three that would appear to be relivent: PREPARE_HITLIST, GET_HITS_PER_PAGE and SHOW_HITLIST. However, I am having trouble tracking down where the default value of 10 hits per page is being set at.

Ctx_doc.snippet increase the number of occurrences returned

Hi everybody,
I am pretty new on Oracle Text so please be merciful :)
I am on Oracle 10.2.0.4.0 and I need to provide my users with ALL snippets found in a text, but it seems that CTX_DOC.SNIPPET restricts the number of snippets occurrences (I will exemplify it later).
The question is: is there a way to increase the number of results/snippets returned by CTX_DOC.SNIPPET ?
In the example that follows, I create the table "mysearch" and an index of type CTXSYS.CONTEXT, then I run the final SELECT query with CTX_DOC.SNIPPET() to obtain a list of most relevant fragments.
If you run the query - see the column "SNIPPET" - record #6 is returning only the first 4 occurrences. In this case (especially because is a single row) I would expect to find all 6 occurrences instead of 4.
Again, if looking to record #7 I have only 3 occurrences.
Then for record #8 I have only 2 occurrences.
I know that CTX_DOC.SNIPPET retrieves the "most" relevant fragment, but I would like to obtain the full list of fragments present in the indexed text. Is there a way (or an alternate method) to accomplish what I like to do.
I have also noted that CTX_DOC.MARKUP can be used on the same index to retrieve the full text "marked-up" with my query terms, so I know Oracle has indexed the text somewhere, I need only to get it out !
Any help will be very appreciated.
Thanks,
Luigi

How can I increase the number of Tags displayed in Drop down list?

When I go to Bookmarks/Tags, there are only 10 tags displayed. I have created at least 15 tags.
Is there a way to increase the number of Tags displayed in the Drop down list?
Thanks

Do you mean "Recent Tags" which has an icon a blue-colored folder with a primitive looking magnifying glass over the folder?
That folder does have a limit of 10 results. If you want to create an "All Tags" item on the Boomarks Menu, you can do that by creating your own "smart folder." The process I use is a little involved, so bear with me (also, see the screen shots).
The query used by Recent Tags is:
place:type=6&sort=14'''&maxResults=10'''
So for All Tags we will drop the maximum results limit:
place:type=6&sort=14
''If you prefer your tags in alphabetical order instead of having the most recently used at the top, use this instead:''
place:type=6&sort=1
Go ahead and select the line you want and right-click > copy it.
Next, click the bookmarks drop-down button, expand the Bookmarks Toolbar, right-click any existing item, and choose New Bookmark.
In Location, paste the query, and in name, type All Tags (or your preferred description). When you click Add Bookmark, Firefox will add it, but it doesn't show the blue search folder icon. Drag the bookmark to the menu, and it will turn into a functioning search folder.
Success?

How can I increase the number of pixels in an image?

How can I increase the number of pixels in an image?

You can't.
The number of pixels in an image is decided by the camera that shoots the image
With an app like Photoshop you can interpolate - this will make a guess as to what a particular pixel may look like based on the ones around it. Results can vary wildly and Photoshop is expensive.

Increase the number of rows in MDXTEST

Dear colleagues,
I use the SAP transaction MDXTEST to test MDX queries generated by WebI reports. The expected result set is significantly larger then 500 rows which causes the following error in MDXTEST:
"There are more than 500 possible inputs
Message no. DH803"
The help message also says:
"With the function 'Restrict values' you can define selection conditions that reduce the number of valid values.
Use the same function to change the maximum number of rows to be displayed."
Can you explain what that means - how can I increase the number of rows retrieved?
Do I have to modify the MDX statement and if so, how?
Is there a menu option or customizing setting for this purpose?
Any help is appreciated.
Regards
Johannes

Official reply from SAP Support: Please be aware that MDXTEST is only a test transaction. Therefore, the display of data has been restricted and you cannot change this.

How to increase the number of access to a list

Hi,
I have a list with many numbers, for example [234, 235, 236, 237 .....]. If I want access to the first value of the list I can use for example the command: "put MyList [1]" and I get 234.
Now I need to have a script that increases the number in square brackets of "MyList" by one unit (MyList[2]; MyList [3] etc..) in order to obtain 235, 236 etc.. If I use the command "setAt" or "MyList [1] = MyList [1] + 1", with "put MyList" I get the value 2, 3 etc.. and not 235, 236 ... that I need.
What might be the way to the solution?
Thanks.

Thanks a lot Production Monkey for your reply,
If I use "MyList = MyList + 1", if my list is equal to the following for example: [0, 11, 123, 234, 6443], the result will be: [1, 11, 123 234, 6443], but it is not what I want. I try to be more clear.
MyList = [224, 336, 445, 224, 779 etc ...]
Now, without changing the values of "MyList", I need to access the first, second, third .... etc value.
The first hypothesis might be:
MyList [1] (I obtain the value 224 and it is good)
MyList [2] (I obtain the value 336 and it is good)
MyList [3] (I obtain the value 445 and it is good)
etc. .........
but the list is very long and change, I would like a script, for example "on mouseUp me" to increase (not the value of the first list [224.336 etc]) but only the single value inside the brackets for example: MyList [4], MyList [5], MyList [6], MyList [7] ... [8] ... [9] and so on.
How can I do?
I apologize for my bad English.

How to limit the number of search results returned by oracle text

Hello All,
I am running an oracle text search which returned the following error to my java program.
ORA-20000: Oracle Text error:
DRG-51030: wildcard query expansion resulted in too many terms
#### ORA-29902: Fehler bei der AusfÃ¼hrung von Routine ODCIIndexStart()
ORA-20000: Oracle Text error:
DRG-51030: wildcard query expansion resulted in too many terms
java.sql.SQLException: ORA-29902: Fehler bei der AusfÃ¼hrung von Routine ODCIIndexStart()
ORA-20000: Oracle Text error:
DRG-51030: wildcard query expansion resulted in too many terms
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:169)
When i looked up the net, one suggestion that was given is to narrow the wildcard query, which i cannot in my search page. Hence I am left with the only alternative of limiting the number of results returned by oracle text search query.
Please let me know how to limit the number of search results returned by oracle text so that this error can be avoided.
Thanks in advance

Hi,
If not set explicitly, the default value for WILDCARD_MAXTERMS is 5000. This is set as a wordlist preference. This means that if your wildcard query matches more than 5000 terms the message is returned. Exceeding that would give the user a lot to sift through.
My suggestion: trap the error and return a meaningful message to the user indicating that the search needs to be refined. Although it is possible to increase the number of terms before hitting maxterms (increase wildcard_maxterms preference value for your wordlist), 5000 records is generally too much for a user to deal with anyway. The search is not a good one since it is not restricting rows adequately. If it happens frequently, get the query log and see the terms that are being searched that generate this message. It may be necessary to add one or more words to a stoplist if they are too generic.
Example: The word mortgage might be a great search term for a local business directory. It might be a terrible search term for a national directory of mortgage lenders though (since 99% of them have the term in their name). In the case of the national directory, that term would be a candidate for inclusion in the stoplist.
Also remember that full terms do not need a wildcard. Search for "car %" is not necessary and will give you the error you mentioned. A search for "car" will yield the results you need even if it is only part of a bigger sentence because everything is based on the token. You may already know all of this, but without an example query I figured I'd mention it to be sure.
As for limiting the results - the best way to do that is to allow the user to limit the results through their query. This will ensure accurate and more meaningful results for them.

Increase the number of portions in process for each conversion object

I experts,
I configured SAP TDMS 3.0 with SP 14 to transfer test data from QAS to DEV (both is ECC 6.0) for the first test with TDMS TIM (Time Based Reduction).
The data transfer phase is still running (99% - 60hs running). We analyzed the Display Runtime Information report and see that objects of conversion with similar calc. records and calc. GBytes have very different the Net Runtime.
TMDS currently is working with four objects of conversion, processing a portion of each.
Conversion objects that are running are:
- Z_LTBP_002
- Z_TSEGE_002
- Z_VEVW_002
- Z_YST27_002
We check in the receiver system, and we see that is use only one DIA process to update the each table.
How can increase the performance of the update? Is correct that use only 1 DIA process for this??
Can I increase the number of portions in process for each conversion object?
Any help is greatly appreciated.
Regards,
Sergio

How, using Adobe Connect can increase the number of participants in the meeting? I need more than 25 people.

Hi, I use licensed Adobe Connect. Earlier in the meeting could involve up to 100 people. Now only 25. How, using Adobe Connect can increase the number of participants in the meeting? I need more than 25 people.
Thanks for your help.

The purchasing option through adobe.com only allows up to 25 attendees. If you need more than that, you will need to purchase through a reseller. You can find one that is able to sell in your part of the world, here: Adobe Connect Partners. Just reach out to one of the Global Partners.
