How to Add Index in Toplink Cache

Hi
We are using toplink as ORM.we are using default cache option (soft cache weak identity)provided by toplink, need to optimize the object retrival from cache, is there any option to create Index ( like database index) on the toplink cache.

The TopLink cache is indexed by primary key only. It does not support additional indexes.

How to add index to PSA table?

Hi , Experts
as title, I want to add index to PSA table.
my scenario is as below:
We have already initialized 2LIS_03_BF with NOT blcok business user(it's due to our company could not stop R/3 system, anyway), so there are 6 years data in the PSA table, it's very huge records in PSA more than 48 million records, because of we NOT stop R/3 business during initialization, so I have to search some common data between delta records and full records(it's due to this common data contain duplicate record, I need find them and delete the duplicate record and make sure the data is correct).
This is mean The selection is too expensive as it has to look for more than five thousand delta record between more than 48 million full records. fow now I have already tigger this search job use a program, but it's still run for 7 days, still not finished yet, it drive me crazy. so I mean if I can create a index for PSA table, and this action will drive the above compare work more quickly than before? or have any other way for my scenario?
Thanks in advance.
Best Regards,
Bruce

Hi,
See the PSA Name in RSTSODS table and then in SE11 you can create Index. But the load will become slow if you don't drop the Index.
Use 2LIS_03_BX, 2LIS_03_BF, 2LIS_03_UM to 0IC_C03 Cube and design the report.
Use :See the steps how to load the data to 0IC_C03.

Setting up material movement/inventory with limit locking time
If it is BI 7 then for BX in in DTP in Extraction Tab you need to select Extacrion mode = NON-Cumulative option.

How to add Index?

Dear All
I am using dbxml 2.4.16 and Berkeley DB 4.6.21 on Mac OSX Leopard using Python APIs.
I want to add index.
The XML document is like
<a:tag1>
<a:tag2 id="bbbb"> <a:tag3 id="123">hello</a:tag3> </a:tag2>
<a:tag2 id="ccccc"> <a:tag3 id="341">hi</a:tag3> </a:tag2>
</a:tag1>
where
xmlns:a="http://somewhere"
In this case, how can I add an index to "id" of tag2?
For example
container.addIndex("", "id", "node-attribute-equality-string", ucontext)
will give index to "id"s of tag2 and tag3.
I tried
container.addIndex("", "tag2/@id", "edge-attribute-equality-string", ucontext)
container.addIndex("a", "tag2/@id", "edge-attribute-equality-string", ucontext)
container.addIndex("http://somewhere", "tag2/@id", "edge-attribute-equality-string", ucontext)
container.addIndex("http://somewhere", "a:tag2/@id", "edge-attribute-equality-string", ucontext)
but it seems that these did not work.
(I checked on dbxml shell using lookupIndex.)
Any suggestions are welcome.

Hi Oyasai,
you almost got it right. To clear things up, the first parameter to addIndex() is the namespace URI - not the prefix. The second parameter is just the element or attribute name - not an XPath expression, as one might think and, indeed, you did think. The third parameter is the index syntax string, which is 'edge-attribute-equality-string', in your case. (I don't know the Python API, so I don't know if a fourth parameter is necessary. In Perl, it isn't.)
The way to have BDB actually use that index is, unless I'm mistaken, to include the parent element name in the XPath used for querying, like this:
collection()[ //a:Broadcast/@cgID='kind' ]Michael Ludwig

Querying TopLink Cache

My system demands caching the result sets obtained from a ReadAllQuery. I might make several queries on this static set of cached data. But the data to be cached is small. I use TopLink's use session.getProject().FullIdentityMap() to cache the output of ReadAllQuery that i execute at the start of the system.
But am not able to query the cache from an external API later ( which could be several minutes later). How can i manipulate the TopLink cache APIs to get this done. Kindly Reply.

Hi Manoj,
If I understand you correctly, you persist some objects and then later query them. You don't get the results you expect when you use checkCacheOnly(). You need to use checkCacheThenDatabase() and when you do this you're seeing SQL I expect.
If your cache type for the class is FullIdentityMap then TopLink will never release objects of that class once read and your checkCacheOnly() query should work.
I'm guessing that you're using a different TopLink session. You mention you have a number of services. What environment are you running in and what is your architecture (e.g., servlet or EJB)? Statics don't solve sharing problems especially in an application server or web application environment in which multiple classloaders are employed.

How to add a new object to Toplink session cache?

Toplink Experts,
I have a question on Toplink 9.0.4.5 (I know this is older version of Toplink but this is what we are using right now). Let me give you little context before I ask the question.
Toplink server session brokers client sessions (that are spawned by it) and gets changes made in client sessions into server session through transaction commits. Process involved in getting some thing into database using Toplink is: 1) Get client session 2) Register object to be written into database with Toplink's UnitOfWork (UOW). This registration creates two copies of the object registered (original object). Working clone for client application for modifications, backup clone for Toplink to compare the changes made to the working clone later 4) Make changes to the working clone 5) Complete the transaction (and so commit UOW). If transaction commits successfully, Toplink writes the changes from the working clone into database first and applies the same changes made to the working clone to the original object in Toplink server session cache next. Oracle recommends using UOW to write some thing into database. Using UOW involves a transaction and it writes changes into database first before the original object in Toplink server session cache is refreshed.
Now comes my question: Is there a way to add a brand new object (persistent object) into Toplink server session cache with out writing it first into database? I am OK if I need to use UOW and also to use transaction to make the change but I just want to be able to refresh the original object in the server session cache with out writing any thing into database. If there is a way to do this? What are the disadvantages in doing this way though? I have read Oracle's Toplink developer guide (10.1.3) and Javadocs from Oracle on UnitOfWork/Session etc all related interfaces and classes but I could not find a way. Please help!
Syam

There are a couple things wrong with the method you posted. The first being uow.registerObject() is going to cause the object to be treated as new if you are not using the TopLink cache.
There really is not any supported mechanism to do what you are looking to do. TopLink 11g has the hooks to replace the TopLink cache with a distributed cache (and the TopLink-Grid product uses these to use Coherence as the TopLink cache) but earlier versions did not have this.
If you are willing to work outside what would be officially supported and no component of the application is using the ServerSession cache (ie all queries refresh) then something like the following may work for you:
public void prepareObjectForSave(Object userEditedObject, Object gigaSpacesObject)
UnitOfWork unitOfWork = this.dbContext.getSession().acquireUnitOfWork();
Descriptor descriptor = this.dbContext.getSession().getDescriptor(gigaSpacesObject);
Object pkVector = descriptor.getObjectBuilder().extractPrimaryKeyFromObject(gigaSpacesObject, this.dbContext.getSession());
Object cloneOfMostRecentlyUpdatedObject = (Object)unitOfWork.cloneAndRegisterObject(gigaSpacesObject, new CacheKey(pKVector), descriptor);
unitOfWork.mergeCloneWithReferences(userEditedObject);
unitOfWork.commit();
}You will need to tweak the above code to have it match the APIs in your version of TopLink and you should test thoroughly.

How to specify index for cache in coherence-cache-config.xml

Hi All,
We want to apply indexing on cache data.
Suppose i have a EMPLOYEE object in coherence cache.
and i want to use employeeID for indexing purpose.
Can anybody help me to achieve this at Congregational level i.e. using xml file (coherence-cache-config.xml) .
Edited by: 981644 on Jan 16, 2013 1:51 AM

Hi,
I've posted some [url http://coherence.oracle.com/download/attachments/14647422/add-index-namespace.jar]code and the [url http://coherence.oracle.com/download/attachments/14647422/add-index-namespace-src.jar]source. It depends on coherence common version 2.3.0.39174 however I believe it will work with 2.0.0.23649 also.

Hi Frank,
mSATA is just a mini-onboard SATA connector where a small circuit board (msata device) can be inserted. Typically it's used as a way with small form factor devices to add SSD like performance.
You can change the SATA controller mode from the default AHCI setting to RAID in the bios. Use Computer Setup to enter the bios. Tapping the ESC key right after power on the PC should bring up a menu selection.

Market Watch - How to Add DJI Index

Does anyone know how to add the Dow Jones Industrial (DJI) Index to
the Market Watch category on the Homepage?

Hi David,
thanks a lot. I did so and it worked, but I found a minor bug while doing so:
I marked the table as "Implement as Materialized View" and went to File->Export->DDL (for Oracle 11g).
The generated code (I checked all options in "Drop Selection") includes a row:
DROP MATERIALIZED VIEW mv_mymatview CASCADE CONSTRAINTS ;
which produces a syntax error.

How do I sync Toplink Cache with my Database?

Hey guys,
We are running macro's through an excel sheet that connects to the database and performs Updates and Inserts.
Since this database update is NOT taking place through TopLink (in a Unit of Work) - we do not see the database changes through the web app on the front end unless we bounce our webserver. Presumably the Toplink cache is re-built on start up...so then we can see the changes.
My question is, what can I do to make sure the TopLink cache is aware of the database changes we have made through the macro without having to bounce the server? Is there a re-fresh or sync command that can be run?
This task is sort of a one time thing, so I don't want a solution that involves the cache going to sync itself on a schedule or anything like that. Maybe bouncing is the best solution?
Thoughts?
We are using Toplink 9.0.4
Thanks.

Hello,
Because it is a one time thing, if you can make sure no other TopLink process are going on, you can probably get away with initializeAllIdentityMaps() or the intitializeIdentityMap(Class) methods on the session. These will clear the identity maps, having the obvious draw back of removing all object identity which will cause problems with running processes though. It might be better than bouncing the server - it depends on the application. Logging out of the session and logging back in has the same effect of clearing the cache, but with a bit more overhead. Benifit is that running processes will get errors if they continue to use the session, rather than strange behaviior if they continue to use objects after identity is lost.
Another alternative is to run refresh queries on the data you know might be in the cache or that might have been affected. Drawbacks are that this brings them into the cache if they are not already there.
TopLink 9.0.4 is a quire a few versions back, and in newer versions there is cache invalidation. An object marked as invalid is not removed, so object identity is maintained, but on the next query the data will be refreshed - ensuring subsequent queries will get results from the database without having to be told explicietly to refresh or being set to always refresh. Invalidation can be triggered on particular objects, classes or the entire cache or different policies can be set to set a time to live etc.
Except for bouncing the server or logging out of the session, all of the above leave some possibility that a concurrent user will still have a reference to stale data and continue to use it after the process has run on the database. So I hope you use optimistic locking and that your batch process updates the version to avoid other process from overwriting with stale data.
Best Regards,
Chris

Querying the toplink cache under high-load

We've had some interesting experiences with "querying" the TopLink Cache lately.
It was recently discovered that our "read a single object" method was incorrectly
setting query.checkCacheThenDB() for all ReadObjectQueries. This was brought to light
when we upgraded our production servers from 4 cores to 8. We immediatly started
experiencing very long response times under load.
We traced this down to the following stack: (TopLink version 10.1.3.1.0)
at java.lang.Object.wait(Native Method)
- waiting on <0x00002aab08fd26d8> (a oracle.toplink.internal.helper.ConcurrencyManager)
at java.lang.Object.wait(Object.java:474)
at oracle.toplink.internal.helper.ConcurrencyManager.acquireReadLock(ConcurrencyManager.java:179)
- locked <0x00002aab08fd26d8> (a oracle.toplink.internal.helper.ConcurrencyManager)
at oracle.toplink.internal.helper.ConcurrencyManager.checkReadLock(ConcurrencyManager.java:167)
at oracle.toplink.internal.identitymaps.CacheKey.checkReadLock(CacheKey.java:122)
at oracle.toplink.internal.identitymaps.IdentityMapKeyEnumeration.nextElement(IdentityMapKeyEnumeration.java:31)
at oracle.toplink.internal.identitymaps.IdentityMapManager.getFromIdentityMap(IdentityMapManager.java:530)
at oracle.toplink.internal.queryframework.ExpressionQueryMechanism.checkCacheForObject(ExpressionQueryMechanism.java:412)
at oracle.toplink.queryframework.ReadObjectQuery.checkEarlyReturnImpl(ReadObjectQuery.java:223)
at oracle.toplink.queryframework.ObjectLevelReadQuery.checkEarlyReturn(ObjectLevelReadQuery.java:504)
at oracle.toplink.queryframework.DatabaseQuery.execute(DatabaseQuery.java:564)
at oracle.toplink.queryframework.ObjectLevelReadQuery.execute(ObjectLevelReadQuery.java:779)
at oracle.toplink.queryframework.ReadObjectQuery.execute(ReadObjectQuery.java:388)
We moved the query back to the default, query.checkByPrimaryKey() and this issue went away.
The bottleneck seemed to stem from the read lock on the CacheKey from IdenityMapKeyEnumeration
public Object nextElement() {
if (this.nextKey == null) {
throw new NoSuchElementException("IdentityMapKeyEnumeration nextElement");
// CR#... Must check the read lock to avoid
// returning half built objects.
this.nextKey.checkReadLock();
return this.nextKey;
We had many threads that were having contention while searching the cache for a particular query.
From the stack we know that the contention was limited to one class. We've since refactored that code
not to use a query in that code path.
Question:
Armed with this better knowledge of how TopLink queries the cache, we do have a few objects that we
frequently read by something other than the primary key. A natural key, but not the oid.
We have some other caching mechanisms in place (JBoss TreeCache) to help eliminate queries to the DB
for these objects. But the TreeCache also tries to acquire a read lock when accessing the cache.
Presumably a read lock over the network to the cluster.
Is there anything that can be done about the read lock on CacheKey when querying the cache in a high load
situation?

CheckCacheThenDatabase will check the entire cache for a match using a linear search. This can be efficient if the cache is very large. Typically it is more efficient to access the database if your cache is large and the field you are querying in the database is indexed in the table.
The cache concurrency was greatly improved in TopLink 11g/EclipseLink, so you may wish to try it out.
Supporting indexes in the TopLink/EclipseLink cache is something desirable (feel free to log the enhancement request on EclipseLink). You can simulate this to some degree using a named query and a query cache.

Reviving this thread again...
I am using DCN feature to build a middle-tier cache. I know oracle has problem sending physical rowid in case of 'Index Organized Table', however, in normal table also its not able to send proper rowid.
e.g, I have 2 records in Table A with rowid AAARIUAAGAAAV/uABw and AAARIUAAGAAAV/pAAX.
I have updated both the records. Strangely for the first record, oracle is sending INVALID rowid, although for the second record its sending the valid one.
Following is the output:
Row 1: (Wrong rowid being sent, AAARIUAAGAAAV/uABw is replaced with AAARIUAAGAAAXDCAAr)

How to add and hide more fields in PPM?

Hello,
Im new to this tool and I would like to know how to add and/or hide customized fields. I've only know that Its somewhere under SPRO > Global Enhancements to Project Elements but Im a little bit lost there. Can somebody explain to me with details how to do this and also, does this need a specific access of developer to do this customization?
As this is a basic need for all, anybody that is new on the tool and search for this will have a good reference on this thread.
Thanks in advance.
Many regards!

The path is SPRO > Global Enhancements to Project Elements > Setup field control.Herein,once you select the field control you may proceed towards defining the conditions that influence the same. A step by step approach is explained in the below article that will aid you to change properties of custom fields.

Here how to add the entries from program to Z-table.???
And one more requirement is I want to provide a deletion checkbox in selection screen . Initial it was unchecked. If I am giving tick mark then the entries should be deleted from above custom Z-tables. this all will done in backgroung job?
Could you please guide me the logic how to crack this???
Let me know if you need more Info
Thanks

Hi Sanjana,
What you can do is to use the ABAP keyword INSERT or MODIFY to add or modify records to a given database table. Here are the syntax taken from SAP documentation:
*Insert Statement
INSERT dbtab
Syntax
INSERT { {INTO target VALUES source }
| { target FROM source } }.
Effect
The INSERT statement inserts one or more rows specified in source in the database table specified in target. The two variants with INTO and VALUES or without INTO with FROM behave identically, with the exception that you cannot specify any internal tables in source after VALUES.
System Fields
The INSERT statement sets the values of the system fields sy-subrc and sy-dbcnt.
sy-subrc Meaning
0 At least one row was inserted.
4 At least one row could not be inserted, because the database table already contains a row with the same primary key or a unique secondary index.
The INSERT statement sets sy-dbcnt to the number of rows inserted.
Note
The inserted rows are finally included in the table in the next database commit. Up until this point, they can still be removed by a database rollback.
*Modify Statement
MODIFY dbtab
Syntax
MODIFY target FROM source.
Effect
The MODIFY statement inserts one or several lines specified in source in the database table specified in target, or overwrites existing lines.
System fields
The MODIFY statement sets the values of the sy-subrc and sy-dbcnt system fields.
sy-subrc Meaning
0 At least one line is inserted or changed.
4 At least one line could not be processed since there is already a line with the same unique name secondary index in the database table.
The MODIFY statement sets sy-dbcnt to the number of processed lines.
Note
