Disable Statistics for specific Tables

Is it possible to disable statistics for specific tables???

If you want to stop gathering statistics for certain tables, you would simply not call DBMS_STATS.GATHER_TABLE_STATS on those particular tables (I'm assuming that is how you are gathering statistics at the moment). The old statistics will remain around for the CBO, but they won't be updated. Is that really what you want?
If you are currently using GATHER_SCHEMA_STATS to gather statistics, you would have to convert to calling GATHER_TABLE_STATS on each table. You'll probably want to have a table set up that lists what tables to exclude and use that in the procedure that calls GATHER_TABLE_STATS.

Disable DSN for specific messages

Hi,
i have a problem, where i wish to disable DSN for specific internal users.
Scenario :
Interal User a sends a mail to special address c,
if mail host of special address c is not available or anything else i wish that internal user a is never informed that c didnt recieve his mail.
Can this be done ?
i thought about doing this with sieve.. but i dont know if DSNs generated by the IMS Master itself are also checked by sieve mechanism....

Please do notice that your bits do not support many of the features you want. And that later bits do. If you offer that to your company, perhaps you could update more often, or at least this time. We're not talking about a new package, here, but just an update to the one you have, that's not doing the job properly.
Also, if you had asked for what you needed at the beginning, I could have helped you better.
What you want is the sieve command, save-copy, or, perhaps monitor. Please see whitepaper, quoted below:
Saving Messages for Document Retention
If the reason you want to capture a copy of the message is for document retention, then you will want to take advantage of the new "capture" sieve action. You have to have iMS v5.2 or better to use this facility. The capture action can only be specified in a system or channel sieve; it is not available in user sieves. The general syntax is
capture "monitoraddress"
The monitor action is the same as the capture action. Users are encouraged to use the 'capture' instead of monitor as it best reflects the function being performed.
This action sends a DSN containing the original message in its entirety to the specified capture address. Since this is a DSN it is effectively a completely separate message so there's little chance of it causing side effects that will alert anyone to the monitoring. In particular, no addresses from the original message appear in the DSN header so there's very little chance of the capture copy getting forwarded to the wrong person by mistake. And even though the original message is encapsulated, it is a MIME encapsulation which means the content is easily accessible in any MIME-compliant user agent.
The capture action is nonstandard and undocumented. It was originally intended to be part of the habanero release, but the backporting of direct LDAP support to 5.2 means it is available in 5.2 as well. We certainly intend to support it in the future.
Saving Messages for Replay
There is an undocumented functionality in iMS for making a copy of messages for archival purposes. It's intended for saving sent messages in the event that they need to be replayed. We did this for folks who send mail via bad links to places where the mail may be received OK by an intermediate host but then subsequently lost on its way to the final destination.
This is done with the MESSAGE-SAVE-COPY mapping table. Entries in that table have the form
MESSAGE-SAVE-COPY
out-channel|from-address|D|msg-filename result
where
out-channel -- name of the channel the message is flowing out
from-address -- originator's address (envelope From: address)
D -- the letter "D" (stands for "dequeue" )
msg-filename -- name of the message file being dequeued.
result -- where to rename the file
Outbound Traffic
To save only messages out to the Internet, do
MESSAGE-SAVE-COPY
tcp_local|*|D|/instance-root/queue/tcp_local/*/* (tab-or-space)$Y/msg_save/$1/$2
Be aware that the archive isn't made until the message is actually dequeued from iMS (i.e., sent successfully or bounced). A rename operation is done (as opposed to a copy operation). As such, the message file has to remain on the same disk that the IMTA_QUEUE lives on.
Inbound Traffic
To capture inbound mail will want to have good control of what machines/pathways a message will take on its way into your systems. If your setup is such that mail always enters the site via an INBOUND relay and leaves the site via know outbound gateways, then inbound message flow is from INBOUND-MTA --> MsgStore machine.
Since you can have multiple MsgStore machines behind any one INBOUND-MTA, you will want to make configuration on the INBOUND-MTA machine such that it will use a dedicated queue to talk to the MsgStore machines. For instance, on the INBOUND-MTA machine, you could setup a rewrite rule in your imta.cnf file for MsgStore-A, MsgStore-B, ... MsgStore-Z like:
Node-A.store.domain.com.au $U%$D@tcp_to_store-daemon
Node-Z.store.domain.com.au $U%$D@tcp_to_store-daemon
and a corresponding 'tcp_to_store' channel which looks like:
! tcp_to_store
tcp_to_store smtp mx single_sys subdirs 20 noreverse maxjobs 7 \
pool SMTP_POOL maytlsserver allowswitchchannel \
saslswitchchannel tcp_auth
tcp_to_store-daemon
This has the effect of routing all mail to any of your MsgStore machines through tcp_to_store channel. Transactions to other machines in your setup will take the tcp_intranet channel.
With this in place you can then throw in a MSG-SAVE-COPY mapping table which reads:
MESSAGE-SAVE-COPY
*|*|D|/instance-root/imta/queue/tcp_to_store/*/* $Y/msg_save/tcp_to_store/$2/$3
the net effect will be a number of queue files in the /msg_save/tcp_to_store directory which are ready for replay. Note the $2 in the sample represents the subdir that the message was already in. As such if you have 'subdirs 20' on your tcp_to_store channel, you will want to precreate the /msg_save/tcp_to_save/000 thru 019 subdirectories with the appropriate ownership and permissions.
To initiate the replay, you want to simply move the /msg_save/tcp_to_store/### directories to the /instance-root/imta/queue/reprocess and issue the command 'imsimta cache -synch'. The MTA will start pushing out those messages to the store(s).
If you want to have multiple replays happening you can kick off parallel runs of the reprocess channel by doing 'imsimta run reprocess &' a number of times.
And, If you want to segregate the storage for each MsgStore machine, you can make new channel in addition to the one suggested 'tcp_to_store' channel. You would then have groups of rewrite rules directing traffic over those channels or you could have one rewrite rule per channel block that you setup. That way you can have distinct entries in your MSG-SAVE-COPY mapping table.
Finally, since there is a rename operation taking place when you use the MSG-SAVE-COPY mapping table, you will want to make sure that at the first pass that /msg_save is on the same device that your queues live on.
Short Term Arvchival
You could setup a process in cron to move those files to a new device on a periodic basis. Better yet, schedule this via the job_controller. For instance, these lines at the top of your job_controller.cnf file:
[PERIODIC_JOB=archive_mover]
command=/usr/iplanet/sitescripts/arc_mover.sh
time=/00:10
will run the arc_mover.sh script for you every 10 minutes. Your arc_mover.sh could look something like:
#!/bin/ksh
# ***Script is untested - should generate some ideas though****
DUMMY=`test -d /var/tmp/timestamp.dir || mkdir -p /var/tmp/timestamp.dir`
cd /msg_save
# First pass
for dir in `find ./ -type d`
do
DUMMY=`test -d /real/storage/area/$dir || mkdir -p /real/storage/area/$dir`
cd $dir
for msgfile in `find ./ -type f -newer /var/tmp/timestamp.dir -name "*.00"`
do
mv $msgfile /real/storage/area/$dir/
done
cd /msg_save
done
touch /var/tmp/timestamp.dir
# Second pass cause we do not know how long we took.
for dir in `find ./ -type d`
do
DUMMY=`test -d /real/storage/area/$dir || mkdir -p /real/storage/area/$dir`
cd $dir
for msgfile in `find ./ -type f -newer /var/tmp/timestamp.dir -name "00"`
do
mv $msgfile /real/storage/area/$dir/
done
cd /msg_save
done

Unable to generate statistics for the table

I have got a staging table of more than 600 columns which has got range portioning. Size of the table is 4GB. The average size of the row is around 3 MB. I have created a Functional index on one of the column ABC VARCHAR2(50) and it has only number values. Now when I try generating statistics for this table through ANALYZE or DBMS_STAT, it gives Invalid Number error but when I drop this index and try analyzing, it works.
Executed TO_NUMBER(ABC) query on the table and it works fine.
I have got Functional Indexes on other tables also but I don't get such problem with those tables. I tried dropping the index and re-creating it but it didn't work out.
I was suspecting DATA BLOCK CORRUPTION so checked ALERT LOG and TRACE FILES but found nothing.
So what is this magic called?

I am using TO_NUMBER on the column.
I have checked the MetaLink for the same problem but could not find anything on that. I still suspect datafile error which I am unable to get in ALERT LOG or TRACE FILES. So I am going to try it this way:
1) Create new Tablespace with New Datafile
2) Transfer the table from existing Tablespace to new Tablespace
3) Create the functional index in the same new Tablespace
4) Try generating the statistics.
5) If it works then create seprate Tablespace for data and Index.
Hope it works !!
Thanks for the reply guys.

Disable Print for specific situations

I Use Adobe Pro X.
Is there a way to make a form not print if certain information is entered? For instance, some forms in our list are for specific clients only. If a user pulls up a form with the incorrect client, I want to add a script that disables the form from being printed or faxed. I already added script to display a warning message, but that won't prevent anyone from printing it - and then the recipient will receive the letter with the warning message - which is potentially worse than just receiving the wrong letter.
Any assistance is greatly appreciated.
Thanks!

Tto detect a specific client, each system the client has would need a spacial file installed on it and the Organization filled in for the Identity object. This will be a real challenge.
Then once the print process is started there is no way to cancel it. You could unhide a hidden form filed and cover the content of the PDF. But then this could easily be defeated.
So in the end, it could be done, but you most likely will not be able to implement it outside of a given organization.

Hello,
If you would like to force the creation of that stats for table MSEG you need to use the -f (force) switch.
If you leave out the -f switch the parameter from stats_change_threshold is taken like you said correctly:
[http://help.sap.com/saphelp_nw70ehp1/helpdata/EN/02/0ae0c6395911d5992200508b6b8b11/content.htm|http://help.sap.com/saphelp_nw70ehp1/helpdata/EN/02/0ae0c6395911d5992200508b6b8b11/content.htm]

You have tried to do this in your second example :
==> brconnect -c -u system/system -f stats -t mseg u2013f collect -p 4
Therefore you received:
BR0154E Unexpected option value 'u2013f' found at position 8
BR0154E Unexpected option value 'collect' found at position 9
This is the correct statement, however the hyphen in front of the f switch is not correct.
Try again with the following statement (-f in stead of u2013f) you will see that it will work:
==> brconnect -c -u system/system -f stats -t mseg -f collect -p 4
I hope this can help you.
Regards.

RFC-enabled authorization checks for specific tables?

I am developing an Excel application which calls several BAPIs and RFC-enabled FMs, most notably RFC_READ_TABLE. While I will provide security at the FM level by checking S_RFC for these FMs, I need to find a way of restricting access for users to specific tables based on certain table fields? Is there any SAP-delivered FM/BAPI that will let me do this?
My understanding is that although RFC_READ_TABLE does check S_TABU_DIS, it only checks tables based on their belonging to a particular table classIt is not checking authorization for an individual table. What this means is that users will need to have access to the table class or classes to which the table or tables belong, for any tables that are being read by RFC_READ_TABLE.
Please correct me if I am wrong in my understanding, or if there is a standard solution for a situation like this.

Hi john,
1. What this means is that users will need to have access to the table class or classes to which the table or tables belong, for any tables that are being read by RFC_READ_TABLE.
U are perfectly right.
2. The users will have to be given rights
   NOT TABLE WISE,
   But authorisation group wise.
3. Note : S_TABU_DIS
   The main purpose of this authorisation object
   is for standard tools like sm30 only.
   Its also used in the FM RFC_READ_TABLE .

amit m.

AUTOMATIC UPDATE STATISTICS for VB* tables ON automatically

Hello All,
We had reviewed our ECC system with SAP and they recommended us to OFF the AUTOMATIC UPDATE STATISTICS for VBDATA, VBHDR and VBMOD.
We executed the script EXEC sp_autostats <tablename>, 'OFF' but the status goes ON after a while.
Checked the SAP note 771352 but did not get proper idea from it.
MS SQL database used is 2008.
Can someone suggest and share his/her experience.
Regards,
Mohit

Hi Mohit,
Did you ran the sap_z* script ?
What is your SP level - did you check 1702325 - Alerts appear for VB tables
Also, I asked to to use NORECOMPUTE - have you tried that ?

Reduce flashback log - disable flashback for a table

Hi,
We have a table which we use only for logging. This information is not essential but there is a lot (given our scale of data :p ) of data (5.000.000 by day)
So we have put the table in nologging (reduce redo => archived),
the insert are /*+ append*/ (reduce undo)
Now, we want to reduce the flashback logs?
Is there a way to disable flashback for a given table ?
thanks
Nicolas

Hi,
first i would use:
alter table tablename nologging;
So you won't generate a lot of redo.
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_3001.htm#CJAHHIBI
I'm not sure you can disable flashback at table level.
You can do that on tbs level.
Hope this helped..

Disabling sorting for a table

Hi All,
I want to disable the sorting function for my table. How can I achieve this? Please help...!!!
-sps

If you are using a JTable, by default row sorting is unable. Infact, to provide you the Table sorting, you have to put the line
JTable table = new JTable (...);
table.setAutoCreateSorter (true) //this enableinto your code or writing a RowSorter.
Otherwise there's no sorter for the Table and you can't do any kind of sorting.

The RPD hierarchies themselves have no security attributes on them. So your left with a workaround or two. First one that springs to mind :
Create the report in question save this as 'Manager' report.
Create the report in question, disable drilling on the column in question, save this as 'Reporter' report.
Deploy both reports to the dashboard in seperate sections and use the section permissions (against the Webgroups those users exist in) to determine which section is displayed to which user.
Maybe more options will come up from other users, but this one is a start.
Hope this helps,
