Sequential read in sm66 - Database size 550GB - system slow for users
Hello,
Currently when we use any standard transactions or custom program, it is going to sequential read in sm66.
We are getting slowness in system due to this issue for users.
Sm66 log:

I understand that if you create Index on these table ( whichever it shows as sequential read ), it will improve the report performance.
Most of the time, system process shows that sequential read on VBAP, VKPA (sales tables), purchase tables, Finance tables and etc.
If sm66 shows as sequential read for few table, that means that corresponding user will get slowness on getting report/transaction output. I agree on that.
Is there any reason other user will get slowness ie if i run Va03 transaction, WE02 transaction which is not relevant to sm66 process over view.
I appreciate, if you give some recommendations reg. this performance improvement and to avoid this kind of sequential read.
I posted the Same question in DB forum also.
I want to get some more idea from this forum also. That is reason, i posted here again.
Thanks

No system available for user mapping in create new group.
Hi Experts,
I faced this problem when i create a new group
"There are no systems available for user mapping for the selected principal."
i checked that my server is running well with other groups.
i would just like to ask what determines the "selected principal"? is it because i select the wrong roles or the roles does not need the system?
i'm confused as some previous groups i created works well until this new group, i've tried to create a new 1 but the problem still exsist.
Thanks.hi,
Define permission to the system that you have created.
right click on hte system that you have ccreated - > in properties dropdown go to permissions -> search the group/ user for which you want to map this system - > and give permission as enduser.
this will make your system accessible while user mapping.

SAP_J2EE_ADMIN, no systems available for user mapping
Hello,
We are using EP 7.0 to run CRM applications (client 100).
We are creating portal users in 001 client of CRM server.
When I try to map users of portal to users of crm through user administration, it says that, "There are no systems available for user mapping for the selected principal".
I discovered that this warning disappears if I give the user has SAP_J2EE_ADMIN role in 001 client. But this time the user has the content adminstrator, user administrator and system administrator tabs as well. I don't want to give administrator rights to everyone.
What can I do?
Any recommendations?I maintained the permissions like Administrator:None, End User:X, Role Assigner:X.
I removed the J2EE_ADMIN role from the user.
But unfortunately the result did not change. The user can not access the CRM system.
Here is the error:
Portal Runtime Error

Exchange 2013 Database Size didn't reduction after user move another DB.
Hi, I have two Exchange Server Ex01, Ex02 and two database DB1 and DB2. Already we move few user DB1 to DB2 but DB1 database size didn't reduction after move user.
Md. Ramin HossainHi ,
If you delete or move a mailbox from a database will not create a free space on that database.Instead a white-space will be created on that database during the online defragmentation and that will not make any changes on the physical size of the database
.Then that white-space will be used when a new mailbox is created on that same database.
In case if you wanted to convert those white space to free space then you need to do an offline defragmentaion and that will make the physical change in the size of the database
Note : For offline defragmentation we should have the database to be in a dismounted state.
Command for offline defragmentation :
eseutil /d "path of the edb file"
But my suggestion would be to move the mailboxes to the newly created database instead of doing the offline defragmentation to attain the free space .Because it would take too much of time for the large databases to get completed.
Reference link for offline defragmentation :
http://exchangeserverpro.com/defrag-exchange-2010-mailbox-database/
Command to see the white space on the mailbox database :
ESEUTIL /MS "path of the edb file"
To execute the above we need the database to be in a dismounted state.

Please reply me if anything is unclear.

Tablespace size. System data vs user data.
Hi,
I have Oracle 11.2.0.1 on Solaris 11 x86_64. Software using SYSTEM tablespace. The free space on this tablespace is allmost end,
When i check what amount of data is collected in database i get strange value:
select SUM(qq.MB) from (select table_name,(num_rows*avg_row_len)/(1024*1024) MB, num_rows, avg_row_len from user_tables) qq;
SUM(QQ.MB)
6,43802738189697265625
So i suppose that data using only 6.4MB.... But statistic for this tablespace is
Tablespace Used MB Free MB Total MB Pct. Free
SYSAUX 655 35 690 5
UNDOTBS1 27 18 45 40
TQTBS 11 489 500 98
USERS 0 5 5 100
SYSTEM 707 93 800 12
What is using 700MB?!It is a very good thing to use the command line queries to understand these things. But it is also good to know your tools. You should check tablespace size with dbconsole, it shows nice little pictures of how much space is used. Note that your system tablespace is autoextend, and this is a good thing, since as Sybrand noted, that's where the PL/SQL is stored. As a practical matter, unless you are adding a lot of new code, that tablespace tends to expand to a steady size and just stay there. You don't want to fix it there, because you might add new code in the future.
On the other hand, sysaux and your data may need some watching. If you are curious, you can use the tablespace map function in dbconsole to see what is where in tablespaces (and there are scripts floating about to see it command line style). But don't stress over it, Oracle is really good about doing things right. What you have to watch out for is things like auditing or plan maintenance becoming space hogs in sysaux, and some apps, sometimes combined with some bugs, can use too much data space. But really, you shouldn't bother with it too much unless you see something using way more space than you would reasonably expect.
If you want to obsess over something, consider patching. 11.2.0.1 is not a good sign. -
Migrating a two ssd macbook pro to newer model (1ssd for system, 1ssd for user home folder)
I want to migrate / transfer the two fast SSDs I have now in an end 2008 macbook pro into a newer mid 2012 macbook pro that is empty and could not find any good instructions on how to do such a move. Both are running the latest version of Mavericks.
On one SSD (265 gig) is the system and applications and on the other 1TB SSD in the optical drive slot are the user accounts - except one safety user account with admin priviledges on the system SSD.
My understanding is that it is not recommended to just swap the system drive from the old macbook to the newer one since there might be complications with drivers etc building up.
My current guess for the best process is to
1. migrate with migration assistant the system from the current SSD to the new slower spinning hard drive on the new macbook pro.
2. swap the two (putting the SSD from the old one to the new macbook, starting in recovery mode and installing mavericks and migrating the migrated system back to the new macbook pro)
3. put the 1TB user folder SSD into the optibay on the new macbook pro, create a new user account with the same name as the one used on the old macbook pro and it should find the user directory with the same name on the second harddrive, ask me if I want to use it and do so ...
Is this was the geniouses out here would recommend also?
My secondary problem is that I have already 5 computers associated to my apple ID and thus am wondering how I can do this transfer without running into problems caused by this - all hints and tips most welcome.I have done what you suggested. However, I have to disagree with you about the 'third party' comment. Although those minor issues were on there which I picked up on shortly afterwards, they were easily removed. It hasn't CHANGED the symptoms I described about my mac. Both items are removed (growl only tends to make your mac 'lag' and that's not the problem I'm having)
I am still having all the above issues, regardless of my mac being fully minus third party items. This mac hasn't had any heavy use, or had many applications installed on it ect, there is really no reason for it to be failing. I'd understand if it was old, but it's literally only just passed being 3 years old.
If you can provide any more help that would be appreciated, thank you! -
How do set the system parameter for user defaults?
When we are creating new users they are getting the European default for date format and decimal format. I have found is there is a structure BAPIDEFAUL that contains these values. However, I have not found the configuration for changing these values. Does anyone have the answer to this problem?
Ronald,
with USERS_GEN, users are created with BBP_USER_CREATECP.
This function uses DEFAULTS to pass parameters.
But those parameters are not available in interface or file upload
USERS_GEN will take default values in system parameters:
Set date format and decimal format like in system parameters
data: defaults type bapidefaul.
clear defaults.
CALL 'C_SAPGPARAM'
ID 'NAME' FIELD 'zcsa/moddatfm'
ID 'VALUE' FIELD DEFAULTS-DATFM.
CALL 'C_SAPGPARAM'
ID 'NAME' FIELD 'zcsa/moddcpfm'
ID 'VALUE' FIELD DEFAULTS-DCPFM.
So, this is the only way to "customize" it: define system parameters zcsa/moddatfm & zcsa/moddcpfm in RZ10.

Hello,
As suggested at various places, I've created an administrator account for system maintainance and installations and a user account for daily use. Now, what I find odd, is that you still can see all folders (different users) and other stuff (system for example) even though you have no priviledges for those. Also, Software Update seems to function when logged in as a user, even though you are not supposed to install software as a user.
I couldn't find anything related in the Mac help files, so I hope you know why this is, and is there a setting somewhere so those folders don't show up? I like to keep things clean and tidyI do documentaries...broadcast ones. And no network has cleared DSLRs for use as cameras. In fact, many actually but them on their DO NOT USE list, along with HDV cameras.
Anyway, I have a tutorial that covers pretty much every tapeless format. Going from when you first put the card from the camera into the computer. Backup, import...labelling. And it mentions Canon DSLR.

GG extract - what is excessive 'control file sequential reads'?
Hi,
base SR - 3-2192225691, GG - 10.4.0.19, database - 11.2.0.1.0, running on Linux x86 64-bit
customer opened SR based on high number of control file sequential read

However, extract traces do not appear to show any waits associated with control files. A 10046 trace has been requested but not done as of yet.
Are there any known issues we can test for, or is this expected behavior? Any further tests that could be run?
Thanks,
SteveSteve,
There is an Oracle internal list you can use. I just sent you email on how to join.
Here's a shot in the dark: I've seen something similar with log sync waits on systems not moving a lot of data (usually a test system) and we're a little eager to get the next piece of data when at the logical end of file. That can be overcome using THREADOPTIONS EOFDELAYMS. Otherwise you'll need to start using the OGG trace commands.
Good luck,

Query on dba_free_space ends in wait by event db file sequential read
Hello All,

I put a trace on the session before the running the above query:

Could someone throw some light into what is happening here ?
TIA,
JJUnder some circumstances querying the dictionary can be slow, usually because of problems with bad execution plans related to bad statistics, try to gather statistics using dbms_stats.gather_fixed_objects_stats(); it has worked for me before.
You can also read Note 414256.1 Poor Performance For Tablespace Page Display In Grid Control Console which in addition points to a possible problem with the recycle bin.

SQL Server 2005 Database Mail - Mail configuration information could not be read from the database.
I'm trying to setup Database Mail and send a test message, but it's not working.
I've done several step-by-steps and all and I can't get it to work. Also checked several posts in this forum but none helped. I think it used to work before (2 months ago) but we had to turn it off.
I've enabled it in Surface Configuration, have tried recreating all profiles, restarted SQL Agent, checked version mismatch...
I check the Database Mail and I get the following message:

User mapping error: NO systems available for the selected principal
I have a problem related to User mapping. After creating system alias, I mapped my j2ee_admin user successfully. Then I created 15 more users and when I click usermapping for all of them, it is not displaying the system alias. It is giving error "There are no systems available for user mapping for the selected principal"
I cannot understand that when I click connection test, it is successful. The user mapping for j2ee_admin user is working. But when I try to do the same for other users, it is not displaying the system alias and giving me the above error.
Can anybody guide me through the error. I have given "Everyone" role to all the 15 users. Any kind of help will be appreciated and points will be rewarded.Hello Abdul,
This is a permission problem. Open the permission editor of the system and assign any role/group in the permission editor and select the checkbox corresponding to end-user.
Now assign this role/group to all the users.
It will solve ur problem.
Regards
Deb

BW System copy from PRD to DEV - Reduce database size
Hi All
We are in the process of copying our existing Production BW system (3.5) to become a new Development & test system. We want to reduce the database size significantly from 1.4 Tb to about 150 - 200 Gb. We have deleted all cube and ODS data as well as much of the master data but still have much tablespace tied up in monitor entries (eg table RSMONMESS) and IDOCs. All of the notes I read say that we cannot delete from RSMONMESS in a "Prodcution" environment, however we are creating a new DEV system and really need to get rid of monitor entries anyway. So there are two questions:
1. Any idea how we can clear up table RSMONMESS or delete unwanted monitor entries ?
2. How can we delete IDOCs copied from our production system without archiving them ? (They are of no use in our new test system.)
Please help.
Many thanks in anticipation.
Paul Sullivan
Orica ITHi Paul,
See SAP Note 694895 - Performance and tables RSMON, RSDONE
Note Language: English Version: 5 Validity: Valid Since 29.11.2005
Summary
Symptom
Tables RSMON* (for example, table RSMONMESS) and tables RS*DONE (for
example, table RSSELDONE) continuously increase in size in the BW system
with each request that is created.
Currently there is no option to reduce these tables.
Do not delete any entries from these tables. If you did, this would have
the following consequences:
When you carry out the next check for the requests for which you have
deleted records from these tables, the check will not run properly.
The status of the relevant requests turns RED in the monitor, and also in
all affected data targets that contain the request.
The affected request and all subsequent requests are no longer visible in
the reporting - all queries on the affected data targets then only display
old data.
Numerous dumps will occur in various situations.
You will not be able to repair the errors caused by the deletion.
More Terms
RSMONMESS; RSSELDONE; Performance; RSMON; RSDONE;
Cause and Prerequisites
This is caused by a program error.
Solution
In the next BW release (BI in SAP NetWeaver 2004s - that is BW 7.0), you
will be able to archive entries from the RSMON* and RS*DONE tables using a
request archiving process that archives the administrative information for
requests.
After archiving, these tables are then considerably reduced in size.
Until then, there is unfortunately no option for reducing the tables.
Rgds,
Colum
