Structural authorisation performance issue

Hi,
For our customer we have the HR-PD object authorisation activated. We now encounter performance issues in the buffering of objects. We have set the buffer/refresh two times a day but this has a huge impact on the resources and hence performance of the system. We actually need to set the buffer to be run more then two times a day (once a half hour) but this is now out of the question.
Are there any settings, configuration, or something else that can be done to improve performance.
Business Scenario: in SAP SLcM* a student is already admitted for a program on faculty (O-unit) X. After a couple months the student is admitted to another faculty (Y) by an employee of that faculty Y (that proces is without authorisation).From that moment on the structural authorisation gets in place. Also on this moment the student is not visible to the employee of faculty Y. After the run of the buffer the student is visible again.

*Also works with HR-PD objects and the structural authorisation from ERP-HCM. SAP SLcM is a industry solution for the higher education market.

Hi rob, what exactly is meant by refreshing the buffer two times a day? Are you running the program RHBAUS00? If so, have you considered tweaking what gets indexed by using program RHBAUS02. Here you can increase threshold, which should limit what type of users actually get buffered when the program runs (so only users with access to many auth objects will actually be indexed).
Let me know if this helps.
Best Regards,
Michael

Structural Authorisation access issue

HI
I am currently trying to implement Structural Authorisation. I have run into a problem and hoping someone maybe able to help. The problem I have is that when a user searchs for employee's in PA20/30 the results show all employee's that are part of the org unit that the PD profile is restricting. However it also includes users that were part of the org unit at some stage.
Now in PA30 the user does not get the header for these users but is able to access/modify some infotypes. I am not sure but I think there is a setting somewhere that will limit the PD profile to only display current employee's of the org unit only but for the life of me can not remember or recall where it is. Can anyone help with this?
Any help will be appreciated,
Many thanks in advance.

Hi,
Did you verify the values for the
Switch ADAYS "HR: Tolerance Time for Authorization Check"
in Transaction OOAC.
Depending on the number of days mentioned.
The person would have access to old Org Unit till the tolerance period if he modified information in that org unit.
Actual SAP documentation:
HR: Tolerance Time for Authorization Check (ADAYS)
Use
    The tolerance time for the authorization check specifies the length of
    time, in the case of an organizational change, that the personnel
    administrator has access to the data he or she created for a person if
    this person already has an organizational assignment outside of his or
    her authorizations.
Input values
    The tolerance time for the time logic for master data infotypes is
    specified in calendar days. In the standard SAP system, the value of the
    switch is set to 15 (= 15 calendar days). When this switch is active,
    that is, when it contains a value greater than 0, organizational changes
    that result in the loss of a particular authorization take effect in
    accordance with the tolerance time.
Example
    ADAYS is set to 15. In the system, only checks with P_ORGIN are active.
    Administrator A has read and write access to data in personnel area A
    while administrator B has read and write access to data in personnel
    area B. It is assumed that for all infotypes the time dependency of the
    authorization check (switch T582A-VALDT) is active.
    A personnel number was assigned to personnel area A until 12/31/9999. As
    of 01/01/2000 this personnel number is assigned to personnel area B. The
    period of responsibilty of administrator A ends on 12/31/9999 but due to
    the tolerance time, he or she continues to have unrestricted read and
    write access to data until 01/15/2000 (inclusive). However, as of
    01/16/2000, he or she no longer has write access to data. Nevertheless,
    the administrator still has read access to all data records with a startdate prior to 12/31/9999.

Performance issues with FDK in large XML documents

In my current project with FrameMaker 8 I'm experiencing severe performance issues with some FDK API calls.
The documents are about 3-8 MBytes in size. Fortmatted they cover 150-250 pages.
When importing such an XML document I do some extensive "post-processing" using FDK. This processing happens in Sr_EventHandler() during the SR_EVT_END_READER event. I noticed that some FDK functions calls which modify the document's structure, like F_ApiSetAttribute() or F_ApiNewElementInHierarchy(), take several seconds, for the larger documents even minutes, to complete one single function call. I tried to move some of these calls to earlier events, mostly to SR_EVT_END_ELEM. There the calls work without a delay. Unfortunately I can't rewrite the FDK client to move all the calls that are lagging to earlier events.
Does anybody have a clue why such delays happen, and possibly can make a suggestion, how to solve this issue? Thank you in advance.
PS: I already thought of splitting such a document in smaller pieces by using the FrameMaker book function. But I don't think, the structure of the documents will permit such an automatic split, and it definitely isn't an option to change the document structure (the project is about migrating documents from Interleaf to XML with the constraint of keeping the document layout identical).

FP_ApplyFormatRules sounds really good--I'll give it a try on Monday. Wonder how I could miss it, as I already tried FP_Reformatting and FP_Displaying at no avail?! By the way, what is actually meant with FP_Reformatting (when I used it I assumed it would do exactly what FP_ApplyFormatRules sounds to do), or is that one another of Lynne's well-kept secrets?
Thank's for all the helpful suggestions, guys. On Friday I already had my first improvements in a test version of my client: I did some (not all necessary) structural changes using XSLT pre-processing, and processing went down from 8 hours(!) to 1 hour--Yeappie! I was also playing with the idea of writing a wrapper to F_ApiNewElementInHierarchy() which actually pastes an appropriate element created in a small flow on the reference pages at the intended insertion location. But now, with FP_ApplyFormatRules on the horizon, I'm quite confident to get even the complicated stuff under control, which cannot be handled by the XSLT pre-processing, as it is based on the actual formatting of the document at run-time and cannot be anticipated in pre-processing.

Performance issue with Hyperion Interactive Reporting Report

Hi,
We created a report in Hyperion Interactive reporting using Hyperion Essbase as database connection file .
Report performance was good in Interactive reporting Studio we don't have any problem in studio.
when we open the report in Hyperion Workspace report performance is very very slow. We are using system 11.1.1.3
Any suggestions to resolve performance issue will be really helpful.
Thanks in advance

Thank you so much, It is working fine when the report is in table structure (List Report. I mean insert a table and drag and drop the fact items and dimention items in to the table)
The requirement is looks like that, it is not a pivot table. Now I want apply the different color or shadow for Item1 and Item 2 in all groups... Please help me.
Total Fact Fact 1 fact 2 Fact 3 ......
Group 1
Item 1 Item 1 000 000 000 000 ...

Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query

Hi All,
There is a Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query in a report painter.
This query is working fine when executed in 4.7 system where as it is running for more time in ECC6.0.
Select query is on the table COSP.
SELECT (FIELD_LIST)
        INTO CORRESPONDING FIELDS OF TABLE I_COSP PACKAGE SIZE 1000
        FROM COSP CLIENT SPECIFIED
        WHERE GJAHR IN SELR_GJAHR
          AND KSTAR IN SELR_KSTAR
          AND LEDNR EQ '00'
          AND OBJNR IN SELR_OBJNR
          AND PERBL IN SELR_PERBL
          AND VERSN IN SELR_VERSN
          AND WRTTP IN SELR_WRTTP
          AND MANDT IN MANDTTAB
        GROUP BY (GROUP_LIST).
   LOOP AT I_COSP      .
     COSP                           = I_COSP      .
     PERFORM PCOSP       USING I_COSP-_COUNTER.
     CLEAR: $RWTAB, COSP                          .
     CLEAR CCR1S                         .
   ENDLOOP.
ENDSELECT.
I have checked with the table indexes, they were same as in 4.7 system.
What can be the reson for the difference in execution time. How can this be reduced without adjusting the select query.
Thanks in advance for the responses.
Regards,
Dedeepya.

Hi,
ohhhhh....... lots of problems in select query......this is not the way you should write it.
Some generic comments:
1. never use SELECT
                   endselect.
   SELECT
into table
   for all entries in table
where.
   use perform statment after this selection.
2. Do not use into corresponding fields. use exact structure type.
3. use proper sequence of fields in the where condition so that it helps table go according to indexes.
    e.g in your case
          sequence should be
LEDNR
OBJNR
GJAHR
WRTTP
VERSN
KSTAR
HRKFT
VRGNG
VBUND
PARGB
BEKNZ
TWAER
PERBL
sequence should be same as defined in table.
Always keep select query as simple as possible and perform all other calculations etc. afterwords.
I hope it helps.

Pranaya

Aperture performance issues.

Dear members:
After some disappointments with the latest version of Bridge (CS3) I decided to start working with Aperture as I found it offered some interesting tools for viewing and selecting images.
First I worked on some test images and everything went well. However, last night I did my first import of "real world" images and experienced severe performance issues.
I imported one folder containing 163 photos to two different locations - the folder and the images were the same but imported into two separate locations in Aperture as I was trying to create the ideal file structure for me.
These are the questions and/or problems I have.
1. This IS NOT a major problem. As much as I tried to import photos into an album or folder I couldn't do it. I don't like the project concept and prefer to have my images placed into folders or albums. My iPhoto library was imported by Aperture using this structure. The iPhoto library is a folder with albums as subdivisions as they were set up in iPhoto originally. However, this doesn't seem to be working as I import photos from other locations.
Q: How can I import photos into folders or albums and completely avoid the projects concept and icons ?
2. This IS major problem. Performance was very poor. I imported the folders last night and waited for approximately 30 min until I decided to turn my computer off. Aperture gave me a message stating that it was still generating previews and asking me if I wanted to quit. I pressed the OK button and turned the computer off. This morning I launced Aperture again and it went back to the spinning wheel on both projects. It must have taken approximately 45 min until the spinning wheels were no longer turning.
This is a problem for me as I have a library with approximately 15,000 - 20,000 images. The ones I imported last night were CR2 generated by a Canon 1Ds MK II (17 MB each). I can only imagine how long it would have taken had I chosen to import the 120+ MB TIFF images I also have in my library from slide scans.
My Aperture preferences have been set for Preview Quality = 12 and Limit Preview Size = Don't Limit. I have it set this way as I don't with to have reduced size previews so that (1) they can display with the highest possible quality as I mostly use the full screen mode for viewing and selecting images, and (2) in case I upgrade to a larger monitor in the near future (I have a 23" cinema display but am planning to upgrade to a 30") the previews will still work with that monitor.
Is this performace typical of Aperture ? I understand my camera is a professional camera that generates large images but isn't Aperture supposed to be a professional application aimed at professional photographers ? And what about those who work with 39 MB images from a Hasselblad or with scanned 120+ MB slide images ?
Is there something obvious I have forgotten to look at or set up in Aperture ?
Thank you in advance,
Joseph Chamberlain

Steve:
Thank you very much for your reply to my post and for your suggestions. Some comments about my experience appear below. I am grateful for your help and don't wish in any way to discuss what you recommend below. I just wish to share my view of this issue and also to try to find the best answers for my problem.
For 1, use File > Import > Folders Into A Project. That will retain your folder
structure using brown folders and albums.
See:
http://www.bagelturf.com/aparticles/library/fivesimple/index.html and
http://www.bagelturf.com/aparticles/library/brown/index.html and
http://www.bagelturf.com/aparticles/library/libinadv/index.html
A. You can't. Projects are the container for everything in Aperture. No
projects, no images. So just live with them and subnvert them any way you
like. I don't have "projects" so I just use months, vacations, events, or
whatever keeps my image collections a reasonable size.
As an user I would like to have control over my own filing structure. This works quite well in iPhoto and I don't understand why Aperture chose to adopt this less flexible file structure. Also I noticed that the imported iPhoto library appears in Aperture inside a folder with multiple albums. Since Aperture can do this for iPhoto I find it hard to understand why it can't do for other imported images.
2. Turn off previews and delete the ones you have. When you find you need > them, use them selectively:
http://www.bagelturf.com/aparticles/previews/pwho/index.html
As stated in my previous post I always (no exception) use the full screen mode for viewing my images which is similar to a slide show. So according to the web page you reference above I would fall under the category of users that need previews.
You don't need high res previews. Aperture already generates thumbnails
for you.
General speed tips:
* Get the best video card with the most RAM you can afford
I can't. My computer is fairly new as it was purchased a little more than 2 years ago. Although it is a fairly new computer Apple no longer offers parts for it. My video card is an ATI Radeon 9600 Pro with 64 MB of VRAM installed. I have contacted Apple about this issue and they tell me there is nothing they can do. I have also contacted both ATI Radeon and nVidia and both have discontinued the only two cards they would work in my system (X800 XT Mac Edition and GeForce 6800, respectively).
* Smaller screens are faster than larger screens
My screen is 23" which I would consider to be a medium size screen by today's standards. However, isn't the purpose of working with Aperture to be able to develop a professional workflow ? And don't most professionals like to use large screens to view their work ?
* Avoid H&S adjustments until all the others are done
* Make sure you have sufficient RAM (2G minimum, 3G on a Mac Pro)
My system has 2.5 GB RAM installed. It has been suggested to me that I should add another 1 or 2 GB RAM as it would improve performance significantly. I have no problem doing that and would welcome that solution if I knew for a fact it was going to address my issues. However, I have already invested too much on hardware and software while still finding myself struggling with the issues I have described. Do you think the additional RAM would solve the problem ?
* Don't use previews unless you need them
Based on what I have read on the pages you referenced it seems to me I am one of those users who needs previews.
* Keep projects small. Use blue folders to group projects
My current filing structure is simple - I four folders each with subfolders containing in average 200 to 1000 images each. Some have as little as 1 image and some have 1000. But the majority would fall in the 300 to 400 images range.
* Rebuild the database once in a while
* Quit other apps if memory is restrictive
It seems in this case that the RAM upgrade I mention above would be helpful. Would it allow me to run other applications while also running Aperture without any noticeable performance alteration ?
To a great extent you have to rethink your workflow once you use Aperture.
Many people do a lot of unnecessary things because they are coming from
an environment that forced them to. Start from scratch and ask yourself
why you do everything you do. Much of the effort you will find is wasted
because Aperture either does it for you or make it unnecessary.
I am trying to simply my workflow as much as I can but not at the expense of quality. Bridge CS2 did a very good job for me. In many ways it was the perfect application althout it didn't have many of the great features I find in Aperture for reviewing and selecting images. First it was simple - all you had to do was to create your own file structure and then point Bridge to the folders as it would create its own previews. Second it was fast - this process happened a lot faster compared to Aperture and Bridge CS3. Third it was high quality - the previews generated were high quality and could be seen with amazing resolution while in slide show viewing mode on my 23" screen. My upgrade to Bridge CS3 was disastrous as (1) it has many bugs Adobe hasn't taken the time to fix, (2) it is slow on average machines requiring the latest hardware to run efficiently which is unrealistic for most consumers and (3) the previews generated are soft and appear pixilated and in poor quality while in slide show view.
I am going back to Aperture after a very disappointing start as I was one of the very first to purchase the software as soon as it was introduced only to be frustrated with all of its bugs and design flaws. Aperture has one of the best interfaces I have seen on any imaging application and I would really like to use but after this new attempt to use and the barriers I have encountered I am not sure I can.

Fetching from LDB PNP - Performance Issue

Hi,
My apologies if my question sounds too basic, but i have not worked in HR earlier. So just needed to clarify once. I've researched it well on SDN , then created a solution but just wanted to check with you guys once, if this the the correct way in HR.
Requirement: Get Data from few infotypes and display report. Infotypes uses 0000, 0001, 002, 0008 and 0102. On selection screen I have Grievances fields from Infotype 0102 say SUBTY(Subtype) and GRSTY (Reason), PERNR and Employment status..
Issue: Performance issue when no pernr is entered on selection screen but GRSTY is entered as 04 and subty as 1. Basically all the records(PERNR's) are fetched with the given selection criteria of two fields(subtype and reason from 0102) and only the the filtered ones are displayed creating performance issues. (seen in Runtime, all pernr's ar fetched)
Solution I Proposed: I've recommended to Select PERNR's from PA0102 table which satisfies the selection criteria before the GET PERNR event and store those PERNR[] in PNPPERNR[] range. The performance changes are visible and better than earlier.
Question: Have i done the right way? Or if there's any other way to achieve it. This is what we do in general ABAP, so just wanted to check with experts, if I've done it correctly.
Thanks,
Santosh

Hi Ramesh,
Thanks for your time. Actually that's the problem, the functional team may want to see all data at once just for a particular reason code and for now, not agreeing for other options. Tried many options but at end came with this approach. Authorizations are do required which is the reason had to include GET PERNR as well.
How this is handled in general scenarios where we do not have a filtering criteria as per the PERNR structure?
Thanks,
Santosh

Change org structure, structural authorisations and MSS team calendar

We are using structural authorisations with evaluation path O-S-P for managers . If I move an employee into a new org unit, when the manager views the Team Calendar in MSS, they can see the new employee. However, if I move the manager into a new org unit from a specific date with the chief indicator ticked, nothing is displayed in the Team Calendar and the message says "no data available in chosen period". I thought it could be an authorisation issue so I have done an authorisation check in Time Managers Workplace for the same manager trying to view an employee in the new org unit and it says it's failing on structural authorisations. If I look in T77UA it shows the correct org unit, positions and employee numbers so I don't understand why it's giving me the structural authorisation error? PFUD has been run and T77UA looks correct - am I missing something??
Any help would be greatly appreciated!

I would check the A012 "manages" relationship and see if its pointing to the right Org unit. We have had several issues with the team calendar and ended up customsing a lot of it.

Hi Subha,
Try implementing OSS Note 766697 in your sandbox and test to see if it fixes your performance issue.

Flex performance issues

hi
By using an mvc architecture ,is it possible to overcome Flex performance issues...???
Thanks
Saritha S

Excuse me ? If you develop a large scale application, you had better use a MVC architectural framework (with or without dependency injection) and additional design patterns like the presentation model. Otherwise, you will end up with code complexity as you try to overcome the inevitable structural problems as the application grows and THIS will end up in performance degradation.
-          Run the profiler to identify bottlenecks and memory leaks: number of instances of a given class, execution time of methods, memory usage … E.g item renderers
-          How much data is loaded, processed and displayed at any one time can have a big impact on performance. Reduce the amount of data: paging via parameter to the service
-          Reduce the layout complexity: remove containers so nestLevel <= 4
-          Remove event listeners: addEventListener () calls with corresponding removeEventListener() calls (do not use addEventListener() with weak reference as it decreases performance)
-          Deferred instantiation of UIComponents (e.g Viewstack children) aka lazy instantiation
-          Garbage collection: check Grant Skinner’s checklist
-          Interrupted execution of complex functions (especially when looping on a large data set): the function monitors its execution time and yields (returns) when the current call exceeds a given duration (usually, that of a frame at 24 fps, which is the default Flex framerate). It is called again on the next frame and so on and so forth until processing is complete. You can use callLater() for that.
-          Lazy loading of data
-          Use more efficient code. Favour re-use of existing code in the Flex framework rather than re-writing what exists. Favour simple solutions over complex ones when possible.
-          UID getter/setter in DTOs for improved performance in sorting / filtering of Array Collections
-          Too many data bindings decrease performance. Mainly use data binding to bind views to the presentation models. Use the ChangeWatcher class or direct assignment of values when possible.
-          Limit the number of calls to setStyle(). Use style declarations in CSS when possible.

About Performance issue

Hi All,
I have a table which is very frequently used for transcational purposes (like Insert,Delete,Update) from Oracle apps database.
I have created a view based on this table only and this view is referenced by another database very frequently using DB Link.
Will there be any performance issue either on view or on table since table is getting used same time in Select queries and also in transcations (like Insert,Delete,Update) from different databases?
is it better to create to Materilized view or normal view for this purpose (Since Mview can be refreshed daily once).
Please suggest..
Thanks

Oracle doesn't have a problem querying tables whilst inserts, deletes or updates are taking place on them. The database engine is designed to be multi-transactional, so things won't hold up a query against the data. The only thing that will slow it down really is the I/O which is primarily related to disc access, so if the physical server is doing a lot of I/O to process the inserts/updates and deletes, then the query may get slowed down as a result of that, but it really depends on the hardware and how the data is spread on the discs.
is it better to create to Materilized view or normal view for this purpose (Since Mview can be refreshed daily once).You could if your business process allows for snapshots of data rather than near-real-time, that's entirely your choice. It won't necessarily help improve the I/O, though it may.
Without your database version, table structures, and details of your hardware, explain plans, test cases etc. there's no correct answer to give you.
Personally, I wouldn't bother with the Materialized view unless I needed to look at a snapshot of the data, or I needed to perform queries using different search clauses from normal such that I needed some different indexes that I didn't want to apply to the base table. I certainly wouldn't consider it just to try and improve performance and take the querying away from the transactional data.

Performance issue on calling the API queryFolders to retrive the subfolders

Hi, We are using 10.3.0 collaboration server.When we make an API call to get the folders under a parent folder, the API is taking more than 2 minutes to return. When we did research, found out that the query collaboration server is executing taking time to return the results from the collaboration database. I am copying the query below. The performance issue coming when the number of sub folders is more than 1400. I did few experiments on this query. When I remove the sort clause, the query is running too fast. If i keep the sort clause and remove the sub query in select clause , query is running fast. But the combination is taking too much time i.e. 80 seconds. Please share your ideas on how to increase the performance of this API call. We are planning to upgrade to another version of collab but not sure whether it would fix the problem. Highly appreciated your valuable suggestions. Let me know if you need more information.

hi reddy,
before applying for all entries on mseg
1.sort t_mard by matnr werks and lgort
2. if not t_mard is initial.
select mblnr mjahr etc...
endif.
these are the main precautions u need to look into before you are using second select.
entires from bseg, mseg will consume lot of time.
so the best if only the fields u r showing are required then take it from the respective table like
ebeln ebelp from ekpo
like that .
so the alternative will be this but this will be the best option if u know only these fields are to be selected .
hope u r getting my point.
yeah swagatika also said correctly that u can go for indexing so the Retrieval is faster.
one more option is construct a view/structure and proceed .
regards,
TVK.

Structural Authorisation - Unrelated Objects

Hi all,
We are facing an issue in structural authorisation of OM objects. The user wants to have authorisation of all objects under his root Org unit alongwith any objects that are unrelated (having no relationship with any Org unit / Positions).
Is this possible with standard configuration? How can this be achieved?
Regards,
VK

Hi VK
Yes it is possible.
You have to create your own function module and assign it to a structural authorization profile (field T77PR-PFUNC)
In this function module, as semvladigo says you have to collect all required unrelated objects and return them via OBJ_TAB interface table.
as a reference please check the following function modules:
RH_GET_MANAGER_ASSIGNMENT
RH_GET_ORG_ASSIGNMENT
Regards,
Sergey

Performance Issues when editing large PDFs

We are using Adobe 9 and X Professional and are experiencing performance issues when attempting to edit large PDF files. (Windows 7 OS). When editing PDFs that are 200+ pages, we are seeing pregnated pauses (that feel like lockups), slow open times and slow to print issues.
Are there any tips or tricks with regard to working with these large documents that would improve performance?

You said "edit." If you are talking about actual editing, that should be done in the original and a new PDF created. Acrobat is not a very good editing tool and should only be used for minor, critical edits.
If you are talking about simply using the PDF, a lot depends on the structure of the PDF. If it is full of graphics, it will be slow. You can improve this performance by using the PDF Optimize to reduce graphic resolution and such. You may very likely have a bloated PDF that is causing the problem and optimizing the structure should help.
Be sure to work on a copy.

SQLDeveloper 1.5.4 Table browsing performance issue

Hi all,
I had read of previous posts regarding SQLDeveloper 1.5.3 table browsing performance issues. I downloaded and installed version 1.5.4 and it appears the problem has gotten worse!
It takes ages to display rows of this particular table (the structure is shown below). It takes much longer to view it in Single Record format. Then attempting to Export the data is another frustrating exercise. By the way, TOAD does not seem to have this problem so I guess it is a SQLDeveloper bug.
Can someone help with any workarounds?
Thanks

Here is the table structure:
create table EMAIL_SETUP
APPL_ID VARCHAR2(10) not null,
EML_ID VARCHAR2(10) not null,
EML_DESC VARCHAR2(80) not null,
PRIORITY_NO_DM NUMBER(1) default 3 not null
constraint CC_EMAIL_SETUP_4 check (
PRIORITY_NO_DM in (1,2,3,4,5)),
DTLS_YN VARCHAR2(1) default '0' not null
constraint CC_EMAIL_SETUP_5 check (
DTLS_YN in ('0','1')),
ATT_YN VARCHAR2(1) default '0' not null
constraint CC_EMAIL_SETUP_6 check (
ATT_YN in ('0','1')),
MSG_FMT VARCHAR2(5) default 'TEXT' not null
constraint CC_EMAIL_SETUP_7 check (
MSG_FMT in ('TEXT','HTML')),
MSG_TMPLT VARCHAR2(4000) not null,
MSG_MIME_TYPE VARCHAR2(500) not null,
PARAM_NO NUMBER(2) default 0 not null
constraint CC_EMAIL_SETUP_10 check (
PARAM_NO between 0 and 99),
IN_USE_YN VARCHAR2(1) not null
constraint CC_EMAIL_SETUP_11 check (
IN_USE_YN in ('0','1')),
DFLT_USE_YN VARCHAR2(1) default '0' not null
constraint CC_EMAIL_SETUP_12 check (
DFLT_USE_YN in ('0','1')),
TAB_NM VARCHAR2(30) null ,
FROM_ADDR VARCHAR2(80) null ,
RPLY_ADDR VARCHAR2(80) null ,
MSG_SBJ VARCHAR2(100) null ,
MSG_HDR VARCHAR2(2000) null ,
MSG_FTR VARCHAR2(2000) null ,
ATT_TYPE_DM VARCHAR2(4) null
constraint CC_EMAIL_SETUP_19 check (
ATT_TYPE_DM is null or (ATT_TYPE_DM in ('RAW','TEXT'))),
ATT_INLINE_YN VARCHAR2(1) null
constraint CC_EMAIL_SETUP_20 check (
ATT_INLINE_YN is null or (ATT_INLINE_YN in ('0','1'))),
ATT_MIME_TYPE VARCHAR2(500) null ,
constraint PK_EMAIL_SETUP primary key (EML_ID)
)

Check Tools | Preferences | Database | Advanced Parameters and post the value you have there.
Try setting it to a small number and report if you see any improvement.
