Block/lock Product hierarchy

Hi Everyone,
We are maintaining product hierachies up to 5 levels in Materail Master Sales data.
If a brand with Product hierachy level 1 and 2 is obsolete and not going to be used in future, i want to block all the postings to this brand (product hierarchy).
can this be achieved by configuration in Product hierachy maintenance OR guide me how this can be done.
Thanks & Regards
Ram

Hi ,
how can i block or lock the materail (master record) for all postings?
Setting a flag for deletion will do? OR is there any other process to Block the material in customizing?
Here the requirement is we identified a brand which is maintained product hierarchy in Sales data as OBSOLETE.
So we dont want any postings should be allowed for the material master in which this Product hierarchy is maintained.
what is the best approach that will meet this requirement???
Regards,
Ram

Blocking Locks

Oracle 9.2.0.8
Our database is used as backend for IIS Servers. Several times per week we experience Blocking locks situation when we could have around 300 – 400 session waiting. Most time when somebody fire up some Update or Delete process. Every time when I check dba_waiters table during this it gives me 10 – 20 holding session. After killing them all things go back to normal.
My question how do I know which one out of this 10 – 20 session is first or real offender. The reason I asked that sometimes after checking SQL’s from several holding sessions they different. And I am not sure which one is the real issue. If I could find this I would be able to go back to developers and see if they missed commit or something in code.

You can use DBA_BLOCKERS and DBA_WAITERS to generate a hierarchy-- the session at the top of the hierarchy is the real offender (assuming, of course, that the locking is not intentional).
In DBA_WAITERS, you'll see a WAITING_SESSION and a HOLDING_SESSION. If you see entries indicating that A is waiting for B, B is waiting for C, and C is waiting for D, you see that there is a hierarchy of locks. Session D in this case is the ultimate culprit (it is blocking a session and it is not blocked by any other session). Of course, in reality, there may be multiple culprit sessions. And you'd want to run the query a couple of times to make sure that what you're seeing is consistent-- if the blockers and waiters change regularly, that's a very different situation than if things are stuck because one session has gone out to lunch.

Identifying the blocking Lock

In one of our production DB we are experiencing huge bottlenecks due to locks. I am using OEM lock monitor to detect and identify the problematic lock. I am trying this out randomly as OEM list all the blocking locks. . Most times I am not able to analyse the problematic locks because of support calls from production. I just have time to kill the sessions and get the platform ready. Is there a script that I can use to identify the session that is blocking other sessions ? How do we do analysis during situations like this? At least I am interested in finding the root cause of the problem so we request the developers to fix it.

Customised Product Hierarchy assignment to application to "Sale" in CRM7.0

hi Gurus,
1.Here my client wants customised hierarchy(say "soldprod") created in sap crm 7.0 to be assigned to application "sale" instead of R3prodhier which is standard, and then he wants ECC products to be migrated as product category under this hierarchy.
is it possible..? or any workaround for this situation..?
2.can we assign application "sale" to two product hierarchy..? as far as i know it is not possible..
Thanks,
gaurav

Hi Tanya
My issue is got sovled with SAP note 1398619 .However, for the second issue there is no finding.
I am assuming ,that is standard SAP CRM behaviour , if we assign any account in crm , that will be shown in the assignment block.

SQL Timeouts and Blocking Locks

SQL Timeouts and Blocking Locks
Just wanted to check in and see if anyone here has feedback on application settings, ColdFusion settings, JBOSS settings or other settings that could help to limit or remove SQL Timeouts and blocking locks on SID's.
We're using MS SQL 2000 with JBOSS and IIS5.
We've been seeing the following error in our logs that starts blocking locks in SQL:
java.sql.SQLException: [newScale] [SQLServer JDBC Drive] [SQLServer] Lock request time out period exceeded.
Once this happens, we're hosed until we remove the blocking SID in SQL. These are the connections to the application.
Any feedback would be great. Thanks!

Hi
This is your exact solution:
Select a.username, a.sid, a.serial#, b.id1, c.sql_text
From v$session a, v$lock b, v$sqltext c
Where b.id1 in( Select distinct e.id1
from v$session d , v$lock e
where d.lockwait = e.kaddr ) and
a.sid = b.sid and
c.hash_value = a.sql_hash_value and
b.request =0;
Thanks

Blocking of products in CRM from R/3

Hi
I have a requirement to block some products in CRM system .My question is what in R/3 needs to be set to make this update in CRM? As our materials are transferred we would need to ensure the master in R3 is correctly set.
When we are changing the status of D Chain specific status in product master(mm02) in R/3, the sales status(commpr01) is getting update in CRM but it is not preventing the order being created using the same product.
I have found a BADI PRODUCT_CUSTOMER2 but don't know how to implement it if is applicable.
Looking for a quick reply.
Thanks.

Hello,
Please check SAP note 495764. It answers how MVKE-VMSTA is mapped to CRM product status.
The BADI is described in chapter 5 of the corresponding documentation 'Customer Enhancement for Download/Upload). You find the document in the SAPNet via the link specified in Note 428989.
I hope the information could be helpful.
Best regards,
Maggie

Mass Update of Product hierarchy in all CRM Open Sales Orders

Hi Folks,
I have a requirement in my project wherein I have to update product hierarchy details with new values in all Items of CRM Open sales orders.
If suppose I have a text file which has the details of Open Orders & new product hierarchy which i have to update, then would it be recommended if I use BDC for this task. Can I Call Transaction CRMD_ORDER?
If someone has already gone through such requirement, Can you please suggest me how to proceed with this requirement. Using BDC or any other way which I can proceed with?
Thanks in advance !!!
Regards,
Nitish.

You are correct in indicating that Exchange rate type field is not seen in Header data of sales order. I checked screen layouts for various screens for sales order data and this field is not suppressed. The only reason could be that this field is not used in sales order screens
If you are interested, you could also check in the following way
1. Go to SE11, enter database table as VBAK
2. Once inside data dictionary table, click where used list button, select programs and screens and execute
3. click continue (don't select background)
4. now you would have list of programs and screens, this table is used
5. now start another session and go to transaction SE51
6. indicate program name as SAPMV45A and screen numbers as listed in step 4. you can check all screen numbers to see whether Exchange rate type field is listed in sales order layout.
7. Of particular interest would be screen number 4311 as this contains Financial accounting data & 4303 Billing data
8. you can check screen layout for screen 4311 & 4303. you would see Exchange rate type field is not indicated.
9. in case you could find this field in any screen, you could ask your ABAP consultant to add this field in the layout screen.
Hope this answers your question

Monitoring blocking Locks

Hi
This question relates to monitoring blocking locks on a 9.2.0.5 2 node RAC
Origionally I have been monitoring bocking locks with every 5 mins using the following query:
"select * from dba_blockers"
I have recently implemented monitoring via grid control this is running an out of the box metric every 5 mins, the sql behind it is as follows:
"SELECT blocking_sid, num_blocked
FROM ( SELECT blocking_sid, SUM(num_blocked) num_blocked
FROM ( SELECT l.id1, l.id2,
MAX(DECODE(l.block, 1, i.instance_name||'-'||l.sid,
2, i.instance_name||'-'||l.sid, 0 )) blocking_sid,
SUM(DECODE(l.request, 0, 0, 1 )) num_blocked
FROM gv$lock l, gv$instance i
WHERE ( l.block!= 0 OR l.request > 0 ) AND
l.inst_id = i.inst_id
GROUP BY l.id1, l.id2)
GROUP BY blocking_sid
ORDER BY num_blocked DESC)
WHERE num_blocked != 0 "
Now.. At one point today the alert using "select * from dba_blockers" fired where as the out of the box metric from gird control did not fire.... alert duration was around 5 - 10 mins
At first i simply assumed that this could have been a brief lock and due to both 5 min intervals being out of sync, the lock had shown and cleared before the grid control interval run.
now im a little more curious.
Is there any significan difference in what these 2 different SQL's will alert on, I was under the impression that DBA_BLOCKERS was simply querying a number of joined views, and Oracle had decided to use V$lock for their out of the box metric as it was more efficient.
Any comments welcome
Thanks

Just to prove that the SQL is correct I have constrcuted a demo for you...
SQL> create table t (a char(1));
Table created.
SQL> insert into t values ('z');
1 row created.
SQL> commit;
in session 1 ---->
select * from t where a='z' for update;
==================================================================
in session 2 ---->
update t set a='x' where a='z';
(session simply hangs)
==================================================================
in session 3 ------>
SQL> select * from dba_blockers;
HOLDING_SESSION
48
SQL>
SQL> SELECT blocking_sid, num_blocked
FROM ( SELECT blocking_sid, SUM(num_blocked) num_blocked
FROM ( SELECT l.id1, l.id2, MAX(DECODE(l.block, 1, i.instance_name||'-'||l.sid,
2, i.instance_name||'-'||l.sid, 0 )) blocking_sid,
SUM(DECODE(l.request, 0, 0, 1 )) num_blocked
FROM gv$lock l, gv$instance i
WHERE ( l.block!= 0 OR l.request > 0 ) AND
l.inst_id = i.inst_id
GROUP BY l.id1, l.id2)
GROUP BY blocking_sid
ORDER BY num_blocked DESC)
WHERE num_blocked != 0;
2 3 4 5 6 7 8 9 10 11 12
BLOCKING_SID NUM_BLOCKED
RAC1-48 1
So back to the origional question,
I am using both these queries from different monitors on my prod syystem, both running on 5 minute intervals, " select * from dba_blockers" fired where as the above query - querying gv$lock did not fire.
Origionaly i assumed that the blocking lock may have simply lasted 3t0 seconds, and due the 5 minute monitor intervals of each metric not being in sync, ... "select * from dba_blockers" may have picked up the lock, then the query selecting from gv$lock ran 2 mins later by which time the lock had disapeared.
-Can anyone suggest any other reasons other than this why one monitor (select * from dba_blockers) picked up the lock and the other (gv$lock) didnt?
Thanks

Using OleDbDataAdapter Update with InsertCommands and getting blocking locks on Oracle table

The following code snippet shows the use of OleDbDataAdapter with InsertCommands. This code is producing many inserts on the Oracle table and is now suffering from contention... all on the same table. How does the OleDbDataAdapter produce
inserts from a dataset... what characteristics do these inserts inherent in terms of batch behavior... or do they naturally contend for the same resource.
oc.Open();
for (int i = 0; i < xImageId.Count; i++)
// Create the oracle adapter using a SQL which will not return any actual rows just the structure
OleDbDataAdapter da =
   new OleDbDataAdapter("SELECT BUSINESS_UNIT, INVOICE, ASSIGNMENT_ID, END_DT, RI_TIMECARD_ID, IMAGE_ID, FILENAME, BARCODE_LABEL_ID, " +
   "DIRECT_INVOICING, EXCLUDE_FLG, DTTM_CREATED, DTTM_MODIFIED, IMAGE_DATA, PROCESS_INSTANCE FROM sysadm.PS_RI_INV_PDF_MERG WHERE 1 = 2", oc);
// Create a data set
DataSet ds = new DataSet("documents");
da.Fill(ds, "documents");
// Loop through invoices and write to oracle
string[] sInvoices = invoiceNumber.Split(',');
foreach (string sInvoice in sInvoices)
    // Create a data set row
    DataRow dr = ds.Tables["documents"].NewRow();
    ... map the data
    // Populate the dataset
    ds.Tables["documents"].Rows.Add(dr);
// Create the insert command
string insertCommandText =
    "INSERT /*+ append */ INTO PS_table " +
    "(SEQ_NBR, BUSINESS_UNIT, INVOICE, ASSIGNMENT_ID, END_DT, RI_TIMECARD_ID, IMAGE_ID, FILENAME, BARCODE_LABEL_ID, DIRECT_INVOICING, " +
    "EXCLUDE_FLG, DTTM_CREATED, DTTM_MODIFIED, IMAGE_DATA, PROCESS_INSTANCE) " +
    "VALUES (INV.nextval, :BUSINESS_UNIT, :INVOICE, :ASSIGNMENT_ID, :END_DT, :RI_TIMECARD_ID, :IMAGE_ID, :FILENAME, " +
    ":BARCODE_LABEL_ID, :DIRECT_INVOICING, :EXCLUDE_FLG, :DTTM_CREATED, :DTTM_MODIFIED, :IMAGE_DATA, :PROCESS_INSTANCE)";
// Add the insert command to the data adapter
da.InsertCommand = new OleDbCommand(insertCommandText);
da.InsertCommand.Connection = oc;
// Add the params to the insert
da.InsertCommand.Parameters.Add(":BUSINESS_UNIT", OleDbType.VarChar, 5, "BUSINESS_UNIT");
da.InsertCommand.Parameters.Add(":INVOICE", OleDbType.VarChar, 22, "INVOICE");

Here is what Oracle is showing as blocking locks and the SQL that has been identified with each of the SIDS. Not sure why there is contention. There are no triggers or joined tables in this piece of code.

Blocking Locks - What Was Likely Going On?

I had a blocking lock yesterday that showed up in OEM under Cluster Database --> Cluster Database Locks. The blocking lock was a row exclusive (RX) table lock that was blocking 175 other sessions that were listed under the blocking lock as having requested row share (RS) locks. It was an hour before I found out about this problem.
Two questions:
1.] The "Oracle Database Concepts 10gR2" book, Table 13-13, states that a row exclusive (RX) table lock can be obtained as a result of INSERT, UPDATE or DELETE DML and that in RX mode share lock modes are not permitted (which is why I had 175 blocked sessions). Does this mean that a user must have been doing a long running (1 hour plus) INSERT, UPDATE or DELETE or is there another more likely cause that I'm not aware of?
2.] The only ways I know of to request a row share lock (of which 175 were blocked due to the RX lock) is by using:
LOCK_TABLE <table name> IN SHARE MODE;
LOCK_TABLE <table name> IN SHARE EXCLUSIVE MODE;
LOCK_TABLE <table name> IN EXCLUSIVE MODE;
I can't imagine a user doing any of these commands so is there another more likely reason that 175 row share (RX) locks were being requested (and blocked)?
Thanks for any insight you can offer. I ended up killing the session that held the RX lock and that resolved the problem but I'd like to better understand what was happening.

1.] The "Oracle Database Concepts 10gR2" book, Table
13-13, states that a row exclusive (RX) table lock
can be obtained as a result of INSERT, UPDATE or
DELETE DML and that in RX mode share lock modes are
not permittedThat table shows that RS (mode 2) is permitted while RX lock is held.
Did you mean to say that sessions were waiting on a S mode (4) lock?
This could indicate that update/delete was attempted on a parent table and that dependend table was lacking an index on fk column. (may answer your q.2)

Blocking locks encountered while splitting partitions in 11g

Background: I've taken over administration of a database that has several date-range partitioned tables that, suffering from a lack of proper administration, have not had their MAXVALUE partition split into the requisite monthly partitions, in almost a year. As a result, in some cases the MAXVALUE partition has 10 million rows (the monthly partitions should average 750K rows).
My understanding is that the syntax I am using to perform the split, should allow for on-line access to the tables while the split is being performed. Here is my syntax without the actual table names:
ALTER TABLE owner.table_name
SPLIT PARTITION MAXVALUE AT
(TO_DATE(' 2012-02-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
INTO (PARTITION PART201201
TABLESPACE tablespace
PCTFREE 10
INITRANS 1
MAXTRANS 255,
PARTITION MAXVALUE) update indexes;
Problem: In attempting to split the MAXVALUE partition into monthly partitions while the database is on-line and accessible, I see application sessions being blocked by my split session.
So, is my understanding above incorrect? Is there some additional syntax that I am missing? Or, are the blocking locks I'm seeing merely transient in nature, and can be ignored? The server I'm running on is not very "beefy", and the split is taking quite a while to run.
Any assistance would be appreciated.

DML that modifies the table cannot be performed on the table while the split is ongoing.
Your bigger problem is that you are using the WRONG method for your use case. If you repeatedly split the MAXVALUE partition you will be repeatedly copying and moving the same ultimate MAXVALUE data over and over again.
DBMS_REDEFINITION is one of your options. But since I just answered this same question 3 days ago see my reply in this thread for a more thorough discussion of your options.

Blocking Locks monitoring in 12c cloud control

Ours is a 11.2 4 node RAC environment, and to check for blocking locks i run a sql script. I want to monitor the blocking locks in the system and if there are any locks for more than say 10 minutes then send out a mail to a group to look into it.
We have 12c cloud control setup, my question is if there is a way to setup alerting/monitoring via 12c for checking blocking locks on all nodes and send out email notifications if there are any. I am not much familiar with 12c, please let me know and if its possible let me know the steps to set it up.

How to find out the reason for blocking locks?

PB Application try to create data in ASE 12.5. With this operation, there are sql, sp, trigger involved. Most of the it is okay. With lock of sleeping or sync sleeping lock. User wait for a short time to get the result.
but some time, there are blocking lock.
If spid for the app is 1. then looks like this app also generate another spid, say it is 2. and 2 is blocking by 1. spid 1 holding lock!
then all user is frozen because of spid 1 holding lock!!! How to figure it out the reason for blocking locks?

Thanks, Mark. Yes, sp_lock, sp_who, ... are common tool I used.
I found out one case like:
I have a SP which call a View for data.
When I run this SP, suppose the sipd is 1. then it will create another spid 2 because of access view and it gone very quick. This cause spid 1 block spid 2 within a short time.
If the are many user run the app, the app will be frozen and everyone is waiting. Finally it release, no dead lock, but the performance is not acceptable.
That why I have this question.
