Fal_Server DOubt

Hi,
We have 1 standby db for my primary db. Connecting from standby db to primary db is disabled.(Port blocked). From primary to standby only opened. Archives are send by primary to standby and it is appliying perfectly.
For testing purpose, We stopped the recovery process and shut the standby server for a day. Then we started it. Now primary send the archive's to standby and it is applying successfully.
My doubt is,
FAL_Server parameter is used when log archive gap in standby and it send the request to service name which is mentioned in FAL_SERVER to fetch the missing log.
But in my case, standby database can't send the request to primary(Due to port blocked).
Now How primary send the archives?
FAL_Server parameter is not required?
What is the exact role of this parameter?
What oracle do after long archive gap occured?
Please help me .
Thanks in advance.

Now How primary send the archives? You should have configured below two parameters in primary
LOG_ARCHIVE_DEST_2
FAL_SERVER
FAL_Server parameter is not required? Of-course it plays a big role in RAC environments, Its recommended to use this parameter.
What is the exact role of this parameter?
What oracle do after long archive gap occurred?Until unless you wont have GAP that should be fine, AFAIK if you have GAP, you will be in trouble, But the mandatory you have to configure in PRIMARY as FAL_SERVER.

FAL_SERVER and FAL_CLIENT

Hi to all,
I am going throught the Dataguard Concepts and Administration Docs.
I have one doubt.
For Eg: My primary db is named as : PRD
Standby DB is name as: PRDSTBY
Now with respect to the init parameters, I mentioning
FAL_CLIENT = PRDSTBY (in PRD init file)
FAL_SERVER = PRD (in prd but this works when switch over right?)
FAL_CLIENT = PRDSTBY (in prdstby but this works when switch over right?)
FAL_SERVER = PRD (in PRDSTBY)
Is my understanding is correct?
Regards,
Vijayaraghavan K

Hi
FAL_CLIENT is the one that is requesting the logs to be applied (the standby server)
FAL_SERVER is the one that is sending the logs to be applied (the primary server)
when you want to test failover and want to make your primary as standby and standby as primary, then the roles become opposite and the FAL_CLIENT, FAL-SERVER would be different.
There is a good paper by Alejandro Varjas where he explains the concepts with a very good demo.
Hope this helps

Few errror/doubts in Primary and Standby server - Need Help

Hi All,
I am having below doubts/errors. I need help to solve all the below questions.
I configured Dataguard successfully. Now the sync is upto date using the below parameters (using 11g):
at primary:
log_archive_dest_1=
log_archive_dest_2='SERVICE=standby.123 arch'
standby_file_management=auto
at sandby:
log_archive_dest_1=
standby_file_management=auto
Still i face below messages in the alertliog. Can anybody clearly explain me all the points.
Primary:
ORA-1652: unable to extend temp segment by 640 in tablespace NEWTEMP
I get this error when my archvie destination got filled up, later we released the enough space, the archived are generating. Still i see this message once in between. Need to solve this.
Primary:
Checkpoint not complete ( i see this message very often, want to get rid of this)
standby:
kcrrvslf: active RFS archival for log thread 1 sequence (sometimes i see this KCRRVSLF)
standby:
check that the CONTROL_FILE_RECORD_KEEP_TIME initialization parameter is defined to a value that is sufficiently large enough to maintain afequate log switch information to resolve archivelog gaps. (also get this message in between the alertlog file in standby)
Standby:
FAL[client]: Error fetching gap sequence, no FAL server specified (this is very often message. How to remove this, what needs to be added. Do i need to add the below parameters)
FAL_CLIENT
FAL_SERVER
Thanks in advance.

Need to solve this.This error has absolutely nothing to do with the handling of archive logs, the status of archivelog destination, or primary/standby. Any relation you thought you saw was pure coincidence.

Here is the very first hit I got when I googled "oracle checkpoint not complete". Tom says it better than I would have.
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:69012348056
standby:
kcrrvslf: active RFS archival for log thread 1 sequence (sometimes i see this KCRRVSLF)
A quick google of that one, and it looks like it is not even an error, but rather simply an informative
>
standby:
check that the CONTROL_FILE_RECORD_KEEP_TIME initialization parameter is defined to a value that is sufficiently large enough to maintain afequate log switch information to resolve archivelog gaps. (also get this message in between the alertlog file in standby)
In that case I would check that the CONTROL_FILE_RECORD_KEEP_TIME initialization parameter is defined to a value that is sufficiently large enough to maintain adequate log switch information to resolve archivelog gaps.
How big is that? Well, at least bigger than it is now. Beyond that, it would have to be "large enough to maintain adequate log switch information to resolve archivelog gaps" Just play with it until you get the result you want.

Fal_srver and fal_client doubt

Hi friends,
I have doubt on this parameter FAL_SERVER and Fal_client.
1.In oracle 11g FAL_CLIENT initialization no more required. then what about FAL_SERVER parameter ?
2.Is it mandatory to initialize the parameters during data guard configuration FAL_SERVER and FAL_CLIENT ?
3.if not mandatory then how automatic gap resolution done in case of dataguard ?
4.what is the role of archiver process in dataguard gap resolution ?
Thanks & Regards
Arya

Hi,
1.In oracle 11g FAL_CLIENT initialization no more required. then what about FAL_SERVER parameter ?
Yes, after 11g version FAL_CLIENT is no more required. FAL_SERVER parameter is require for data guard configuration.
2.Is it mandatory to initialize the parameters during data guard configuration FAL_SERVER and FAL_CLIENT ?
FAL_SERVER paramater is only for mandatory standby database. because, RFS using FAL_SERVER parameter for request redo changes.
FAL_SERVER is primary database.
3.if not mandatory then how automatic gap resolution done in case of dataguard ?
It is mandatory. When Automatic Gap Resolution is using standby database, RFS process using FAL_SERVER parameter for request
redo from primary for resolution redo gap.
4.what is the role of archiver process in dataguard gap resolution ?
When occur redo gap. Standby send request to primary via RFS, requested archive log sequence#.
NLS send info to ARCH process, and ARCH process connecting to standby RFS and sending requested archived log.
and MRP apply received archived logs.

of any existing object, then what should we enter in the Program field for creating the object?
I hope I am clear with my question.
Thanks in Advance,
Saket.

Hi Saket,
Following will be required for created a custom business object.
1. Object Type - ZTEST (Internal Techincal Key)
2. Object Name - ZTESTNAME (Technical Key Name)
3. Name - TEST (Name of BO, it is used while selecting the object type)

PI' RFC Connection pool doubt.

Hi PI exports:
i have a doubt about pi' RFC Connection pool ,pi RFC receive channel can set the conn pool size ,but when start the rfc receiver channel ,is there always only one Connection pool ,or there is only one Connection pool instance?
thinks
Edited by: kevin liang on Oct 19, 2009 6:45 AM

Hi,
Connection poolins size means how many number of connection you want to make open to send data to ECC, We can define maximum number of connection in Receiver RFC Adapter,Go to additional parameters section and define Max Number of connection give the number there,thats it.Internally it works as Connection poolin mechanism.

Small Doubt Regarding SY-MANDT

Hi All,
     SELECT changenr FROM cdhdr CLIENT SPECIFIED INTO CORRESPONDING FIELDS OF TABLE it_cdhdr
                                         WHERE mandant = syst-mandt
                                         AND   objectclas = 'MATERIAL'
                                         AND   objectid   = wa_matl-matnr
                                         AND   tcode      = 'MM02'.
     I have written the select stament as shown above.
     In this i have a doubt like adding a field sy-mandt in the where condition will increase the Efficiency of program or not.
regards,
raghu.

Hi..
No doubt the efficency would be affected but from business point of view there will many things that need to be checked as in:
If you are viewing data from CDHDR and CDPOS which is client specific then you are not viewing complete data.
These tables give us and document changes made to a particular object in SAP but if anything is cross client like company code(lets assume) then changes to it wont be visible in all the clients..
so there can be some key information you can miss out while working on some of the objects.
else in this case its good to make query cross client.

vishal

Doubts with control break statements on internal table loops (AT/ENDAT)

Hi, i've had a couple of doubts for a long while which I hope someone can clarify today:
1) I know how to use the AT statements, however, i'm not sure I get correctly what this part of help regarding this commands means:
"The control level structure with internal tables is static. It corresponds exactly to the sequence of columns in the internal table (from left to right). In this context, the criteria according to which you sort the internal table are unimportant."
I've always sorted the internal table before the control break and it works that way. For example:
SORT ITAB BY EBELN EBELP.
LOOP AT ITAB.
AT NEW EBELN.
* Code for the order header
ENDAT.
ENDLOOP.
If I don't sort the internal table, it doesn't work! (i get dupplicated processing). In the example, if i have more than one register with the same EBELN and they're not consecutive, the header gets processed twice. I really don't get that part of the help text.
2) I know this: "At the start of a new control level (i.e. immediately after AT), the following occurs in the output area of the current LOOP statement:
All character type fields (on the right) are filled with "*" after the current control level key.
All other fields (on the right) are set to their initial values after the current control level key."
My doubt is: WHY is that this way? Because sometimes (most times) I need those fields INSIDE the statement! So when that happened i've solved it in one of three ways:
LOOP AT ITAB INTO WA_ITAB.
WA_ITAB_AUX = WA_ITAB.
AT NEW FIELD.
 WA_ITAB = WA_ITAB_AUX.
* ...Rest of the code for the first register
ENDAT.
ENDLOOP.
LOOP AT ITAB INTO WA_ITAB.
AT NEW FIELD.
 READ TABLE ITAB INDEX SY-TABIX INTO WA_ITAB.
* ...Rest of the code for the first register
ENDAT.
ENDLOOP.
* (Without AT)
LOOP AT ITAB INTO WA_ITAB.
IF WA_ITAB-FIELD <> FIELD_AUX.
 FIELD_AUX = WA_ITAB_FIELD.
* ...Rest of the code for the first register
ENDIF.
ENDLOOP.
Is there any problem with this way of coding? Can be done better?
Thank you very much in advance.

Hi..,
1)
See if u sort the table on a field on which u r using AT ENDAT .. then all the records which are having the same value for that field will form a group or those reocrds will be at one place.. so when u sort the table for all the records AT ENDAT will get executed onli once..
If u dont sort this table on this field then all these records will be at different places and in between there may be records with different value for this field.. so this AT ENDAT will get executed for each record !!
2)
No u cannot use the Right hand fields of the field in the table .. Because these AT events work as Group based operations... So till that field on which AT ENDAT is working it breaks that record into two groups.. One is the left hand fields including that field.. and right hand fields as another group.. and makes the right hand group as stars ****. Thats y u can observe that even any one field in the left hand group changes the AT ENDAT will get executed !!!!
Hope u understood !!!

Doubt on Rows and Coloums in BEx Query Designer.

Hello, Experts.
I have a Doubt in BEx Query Designer.
In the Rows I have a Fiscal year Period, if the user enters the Fiscal year period for e.g. : 001/2006 .
in the columns i have forecast for the Fiscal year period which user entered ( 001/2006 ),   and we have another column pervious ( Prior )fiscal year period ( 001/2005 ).
My Questions is , as we are Restricting with 001/2006 will the query retrieve the values of 2005 or not?
Thanks in Advance .
Sharp

yes i am Doing Offest.
I moved this Fiscal year Period to Free char,   and i Restricted with Pervious Fical Year period and Fical year period . it worked. but
when i kept this in Rows and deleted Previous Fiscal Year period . it is displaying blanks.   in prior years forecast.
is it because i am Ristricting it to only fical year period which user entered
         Colums--> Forcast ( User Entered year )          Prior year
Rows
Fiscal year period
Fiscal year period( user enterd )

change the productid also but I am getting error like some signature is wrong try with different signature. I am confused how to do it .
Any help,
Thanks...

Infoset doubt

Dear Gurus,
i have a doubt regarding use of infoset in BI.
An infoset consist of , on the left, a DSO containing line items loaded from R/3.
On the right is a master data attribute loaded data from a user defined datasource based on a transparent table in r/3.
This master data has a single Key. Its a numeric like serial number field.
The transaction data in the DSO also has this field as part of the transaction data field (non-key).
A Left Outer Join is made between the 2 using several fields joining together. However, the key field in the master data is not joined even though both sides has it. Both this field in each are not joined.
So, by theory of a left outer join, All data not found in the master data will still be selected via the infoset.
I wish to understand :
1. by a 'join' does it mean its not a union? I assume so. But based on the meaning of left outer join, it sounds to me like a union?
Correct me if i am wrong.
2. what is the effect of not joining the master data key field to the same field found in the data part of the transaction data?
best regards
Bass

hi,
point 1:
am i right to say
If all data on the left is picked, and some latest data in the master data is not found in the left, only all the left side data is displayed am i right? so, what is not in the right (master data attr) will not be selected by the infoset?
left outer join will be more clear with an example to you, suppose you are joining cube and master data to pick attribute value from master data. let us say the master data has below value.
master data     attribute
100                ABC
102               XYZ
103              DEF
Now in cube you have data
cube field
100
101
105
106
the infoset wll be returning the value as shown below for different scenarios
left outer join: all values in cube.
field    attribute
100      ABC
101        #    (no value in master data)
105       #    (no value in master data)
106       #    (no value in master data)
Inner join: common records
field    attribute
100       ABC
Right outer join
field    attribute
100                ABC
102               XYZ
103              DEF
point 2:
am i right to say
its just slower performance and the rest being similar effect as joining the key field?
So, if i join the key field it will be faster and the result is the same as not joining the key field of the master data to the transaction data?
no the join determines the amount of data it will be returning as explained above, you should define the joining conditions based on your business logic, like in the above case if the two fields should have same value and are the comparing criteria then you should join those as it would help in retrieving faster results.regards,
Arvind.

DSO - Key Field doubt?

Hi All,
I want to know the functionality of the Key Field in the DSO.
I know based on the Key Fields(Primary Key) data is pulled to DSO, but please explain me the below scenario
E.g
I have 3 records in the Extractor( Generic) and i am pulling data to DSO - Full load.
Material                 Qty       Date
100                       20        1-Jan-2010
100                       30        5-Jan-2010
100                       10        10-Jan-2010
In DSO i have only one Key field called 0MAT_NM (Material Number), but i have 3 records in the Extractor , shown above.
Now my Question is
On what basis data will be pulled to DSO?
Whether latest date records will be pulled to DSO or let me know correct method? because i have got material no 100
but date and Qty is different (means one time it is taking Qty - 30 and date as 1st Jan 2010, other run it is taking differnet).
Please clear my doubt.
Regards,
Nithi.

in your dso you can have one record per key. keyfigures will be in addition or overwrite option. if in "addition' the value will be the sum of all the values for a given key. in 'overwrite', you'll only keep the last record written to the dso; char are always in overwrite, so you'll keep the last record written to the dso
