WAAS CIFS object caching
It is possible during a CIFS session to catch CIFS objects (files) in both WAAS across a LAN?.
One of the WAAS is located close to the server (where the files are) and the other is located across a WAN at a branch location where the files are being dragged.
The idea is that, initially, the files were moves from the client to the server and then back to other client on the same location:
My understanding is:
When the files are move from the client to the server, the CIFS WAAS at the server location is filled and when the files are move back to another client at the same branch office the WAAS CIFS at the branch office is filled.
Thanks
Zach
There are two WAAS CIFS caches: The Brand WAAS CIFS cache and the Main site (Where the servers are) WAAS CIFS cache.
I am interesting in filling the Brand WAAS CIFS cache.
Initially files are going to be transfer from client TO server. According to my knowledge, in this scenario, the WAAS CIFS cache on the server side is filled on NOT the Brand WAAS CIFS cache.
I know, for a fact, that when you transfer a file from server TO client, the Brand WAAS CIFS is filled and the Main Office WAAS is NOT.
Thanks
Server is on Main Office and client is on Branch office.

Error ACLContainer: 65315 does NOT EXIST in the Object Cache for parentID:
Expert,
I did the following steps to upgrade the OWB repository from 10g to 11g
• Created a dummy workspace in the 11.2 repository
• Created users in the destination environment
• Run Repository Assistant against the 11.1 source database
• Then selected *“Export entire repository to a file”* and selected the MDL(10g) to import
After 99% of completing I have got the below error
Error ACLContainer: 65315 does NOT EXIST in the Object Cache for parentID: 65314
Please let me know the solution.
Thanks,
Balaa...Hi I had the same error and worked on it for almost a week with no success but there is few work around for this try it it might work for you.
Step 1>Run a health check on OWB 10.2 enviroment(make sure you clone your OWB 10.2 enviroment and then do this healthcheck ,these checks are tricky )
refer
Note 559542.1 Health Check of the Oracle Warehouse Builder 10.2 Metadata Repository
This will give you info about your missing ACL
Step 2> download these two scripts fixLostACLContainer.sql ,fixAllACLContainers.sql
please refer :
Note 559542.1 Health Check of the Oracle Warehouse Builder 10.2 Metadata Repository
OWB 10.2 - Internal ERROR: Can not find the ACL container for object (Doc ID 460411.1)
Note 754763.1 Repository Cleanup Script for OWB 10.2 and OWB 11.1
Note 460411.1 Opening Map Returns Cannot find ACL Containter for Object
Note 1165068.1 Internal Error: Can Not Find The ACL Containter For for object:CMPPhysical Object
It might resolve this ACL issue but it did not work for me.
If none of these work then
Perform export from design center of OWB 10.2 and import through design center of OWB 11.2.(ONLY OPTION)
It worked for me.

How to get first row from View Object cache.
hi,
I am using Jdeveloper 11.1.1.6
can we get first row from View Object cache??
Thanks in Advance.
Best
ShashidharHi Frank,
Thanks for reply!!
My case is:
I have a Query based ViewObject.
One of the field is LOV and remaining fields are in ADF table. the LOV field is out side ADF table when i insert first record in ADF table and i choose LOV filed the value is selected.
when i create second row LOV value got refreshed because both are in same VO.
I need to get the LOV value of first row and set same value to second Row.

Usage of Object Cache for Java in J2EE apps
Hi,
we are investigating on whether we can use the Object Cache for Java
(OCS4J) for our requirements. The question we have come across is:
What is the designated way of integration for the Object cache to fit
into the J2EE environment? Unfortunately, although the current manuals
group OCS4J into the "Oracle Containers for J2EE Services Guide" and the
suggested package name for the whole thing in JSR 107 seems to be
javax.util.jcache, there is very little documentation on how the
designers would like J2EE programmers to use the cache from within a
J2EE app and all examples given are not from within a J2EE environment.
We are in particular thinking about a hierarchy of several cache
"compartments" (Region->Subregion->group) for different topics and using
the hierarchical name of the cache (region.subregion.group) as the
primary key for BMP Entity beans, each of them having their own
CacheAccess object. Then we would have an API of stateless Session beans
on top of that, which would be determining the cache "compartment", get
the appropriate Entity Bean with the Cache Access object and then do the
required operations on the cache.
But then we immediately run into the question of how the mapping between
Cache Objects and CacheAccess objects will be done etc.
So is there anybody that can give us any hints how to use the OCS4J in
an EJB scenario?
Thanks in advance for any help!
Andreas Loew
[email protected]We have Java client requesting over HTTP to application server. We would like to cache some of the objects created by the servlet while serving the request. Can I use the OCS4J for caching the Java objects. Do I require any software or just copying the JAR file and importing the class would serve the purpose?

Lifetime of Object in the Object Cache on selects
On inserting an object (corresponding to user-defined SQL type), I can use a stack-allocated struct for the object and its indicator structure, and pass these addresses to OCIBindObject.
But on selecting an object (by value, not ref), the doc says one must let the OCI runtime allocate the object struct and its indicator struct in the Object Cache, and call OCIObjectFree when done with the object. But it's unclear whether one needs to free the object for each row of the result set processed, or only once all rows have been processed.
By looking at the cache-allocated addresses of the object/indicator structs, it looks like the same "instance" in the cache is re-used for every row (addresses remain the same for every row). This tends to indicate the same object is reused, as opposed to a new one being allocated. I added a single OCIObjectFree after processing all rows, and things look OK... (read no crash, no complain/error from OCI).
But I feel a little uneasy about this, because unlike in my case, when the object has secondary allocations associated to it (because the type contains strings, collections, or other objects members), if somehow I need to OCIObjectFree for each row, and I don't, then I'm leaking all the secondary storage from previous instances of the object.
Can someone please shed some light on the subject? I find the OCI doc often a little sketchy on these very important lifetime issues. I'd appreciate some advice from someone with Object-Relational aspects of OCI.
Thanks, --DDwhen I have to select objects by value :
* I let oci allocate objects in the object fetch arrayI don't think we have a choice here in fact. At least the way I interpret the doc.
* I have different addresses for every entry in the array after the fetchBut even an array fetch is done is a loop. You fetch 10 rows at a time, and you get say 25, so you have 3 iterations / fetches.
Of course the 10 object entries of a given fetch are different, but is the address of the 6th object the same in the first, second, and third fetch?
* I call OCIObjectFree() for every entry of the
array.If I have retreived object based attributes
from the object, i call OCIObjectFree() on the
object attributes recursively.To made it easier to understand my question, please find below the pseudo-code of what I'm doing (all error checking and most boiler plate arguments OCI requires are omitted, to concentrate on the control flow and the calls made)
create type point_typ as object (
x binary_float, y binary_float, z binary_float
create table point_typ_tab (
id number, point point_typ
struct point_typ { // C-struct matching SQL User Type
float x, y, z;
struct point_ind { // indicator structure for point_typ
OCIInd self, x, y, z;
static void select_objects() {
Environment env(OCI_OBJECT);
env.connect(zusername, zpassword, zdatabase);
OCIHandleAlloc(OCI_HTYPE_STMT);
OCIStmtPrepare("SELECT id, point FROM point_typ_tab");
ub4 id = 0; OCIDefine* define_id = 0;
OCIDefineByPos(&define_id, 1, &id, sizeof(id), SQLT_UIN);
OCIDefine* define_pt = 0;
OCIDefineByPos(&define_pt, 2, 0, sizeof(point_typ), SQLT_NTY)
OCIType* point_typ_tdo = 0;
OCITypeByName("POINT_TYP", OCI_DURATION_SESSION,
OCI_TYPEGET_ALL, &point_typ_tdo);
point_typ* p_pt = 0; ub4 pt_size = 0;
point_ind* p_pt_ind = 0; ub4 pt_ind_size = (ub4)sizeof(point_ind);
OCIDefineObject(define_pt, point_typ_tdo,
(void**)&p_pt, &pt_size, (void**)&p_pt_ind, &pt_ind_size);
sword rc = OCIStmtExecute(0/*row*/);
while (OCIStmtFetch2((ub4)1/*row*/, OCI_FETCH_NEXT) has data) {
if (p_pt_ind->self == OCI_IND_NOTNULL) {
// Use p_pt. Value of p_pt same for all iteration
OCIObjectFree(p_pt);
OCIHandleFree(OCI_HTYPE_STMT);
}As you can see, I do a single OCIObjectFree after the loop, and as mentioned previously, p_pt's value (a point_typ address) remains identical during the iteration, but the values in that memory chunk do change to reflect the various point instances (so each point instance overlays the previous one).
Are you saying I should be calling OCIObjectFree(p_pt); inside the loop itself?
And if so, should I call OCIObjectFree(p_pt); even if the indicator tells me the point is atomically null?
That what I do in OCILIB, and it doesn't seem to leak.Reading your post, I'm unsure you free of points in the array after the loop, or inside the loop. I hope the pseudo-code I posted above help to clarify my question.
BTW, OCCI is just a wrapper around OCI. Because OCCI
first releases were buggy (it's getting better) and
just few compilers (and compilers versions) are
supported, OCI remains a portable and workable
solution for dealing with Oracle ObjectsAs I wrote in a separate reply in this thread, I also agree OCI is the way to go, for various reasons.
Thanks for the post. I'd appreciate if you could confirm or not whether what I'm doing is consistent with what you are doing in OCILIB, now that I'm hopefully made my question clearer.
Thanks, --DD -
Cache distribution - Java object cache

Oracle Application Server 10g Java Object Cache
Hi,
I am new to Java and looking for a java caching framework and just came across Oracle Application Server 10g Java Object Cache. I am unable to find 11g version of the same. Is it not supported any more?
Can I use this with weblogic server? Please suggest if any other alternatives.
Thanks,
ManojBump.
I definitely don't see the same file: C:\dev\jdevstudio10134\javacache\lib\cache.jar in the Oracle JDEV tree. Is there a suggested alternative? -
View Object Index Lookup Into The View Object Cache
Simple question ... and I feel somewhat stupid for asking ... but I'd really like to make an effort here to take advantage of view object caching as opposed to killing our database.
Situation:
I have a lookup table called CodeValue which has two fields of interest here 1. CodeValue.CodeValue and 2. CodeValue.CodeValueCode. This lookup table could be on any of probably ten different databases ... and the primary keys (CodeValue.CodeValue) could be different between them. The secondary unique identifier of each row is CodeValue.CodeValueCode and is equal on all databases.
Problem:
I would like to query my view object with a unique value and if the row is not in the cache it will go out and get it. I am unsure of how to do this with using bind variables (setWhereClauseParam) without re-executing a query each time. In addition, I don't think a setWhereClause with just a basic view of the entire table will do the trick.
Question:
How do I query my view object using a uniqe value with it going to the database ONLY when it does not have that unique value in it's rowset (and I do not want to iterate over the rowset using an equals on each row's unique value ... nor do I think I should hash the CodeValue table and look it up via a key of the unique value ... ADF should do this for me)?
Here is my code that shows kind of what I've been thinking but the isExecuted method is probably not the way I want to go.
<code>
CodeValueCodeFromCodeValueViewObjImpl cvVO = getCodeValueCodeFromCodeValueViewObj();
cvVO.setWhereClauseParam(0, codeValue);
if (!cvVO.isExecuted())
cvVO.executeQuery();
cvVO.setRangeSize(-1);
cvVO.setRangeStart(0);
Row[] rows = cvVO.getAllRowsInRange();
boolean found = false; // Shouldn't be used, only one row
for (int j = 0; (j < rows.length) && !found; j++)
Row row = rows[j];
rtnVal = ((String) (row.getAttribute(CodeValueCodeFromCodeValueViewObjRowImpl.CODEVALUECODE)));
found = true;
</code>

Occi problem about object cache!
Hello!
I have a table named "ggg" which include two column in the oracle database,and the datatype of one colume is "mdsys.sdo_geometry".I insert 1000000 rows record into the "ggg" table.Now I want to download all the data with occi.At the client,i use "sdo_geometry" class created by ott to access the "mdsys.sdo_geometry" objects in the table.Then,problem come:
1.the meomery used by the client applacation grow and grow continuously;the client object cache has not release the object automaticaly when over 8m default cache as the guide of occi;
2.I can not release the occupied memory of the client object,the "delete" methed of the "PObject" is usefulless;
3.the "setdatabufer" methed of the "ResultSet" cann't apply to the object type(exsample:sdo_geometry).
why?
thanks a lot.You didn't mention how you are getting the objects to the client. Are they value instances or are you getting the Refs and dereferencing them?
If you are dereferencing the Refs, make sure the Refs go out of scope when they are no longer used. Otherwise since you are holding them, they won't get garbage collected. -
Java Object Cache have wired behaviour
HI,
I am trying to get my Oracle Java Object Cache working but I am observing some really stange behaviour which has stop it working. So any help will be really useful (10.1.3 and 10.1.2.0.2). I will explain:
Progammaticly I have setup a parent region call 'DatabaseDataCache' and a sub-region call 'country'. In this region I have defined my object call countriesDto' with a Attribuite that has a CaheLoader attached. In my cache loader I connects to a Entity EJB that loads a bunch of DTOs into the cache.
What is strange is that when i run the unit test on the code (cactus). The cache seems to call the cache loader 3 times consequtively before the EJB will load the data (i know this due to debuging messages)
Then in the actual implmentation I have the cache setup code of the in the init() of the servlet but again the cache loader doesn't seem to able to call the ejb it requires. Ones the cache is access it trys to call the cache loader and of course the ejb dosn't get called and is returning me a NullPointerError as I am trying to acces the local interface (in the cache loader). This is strange as in the cactus test it actually calls the ejb ok bit only on the third attemp.
I am abit puzzled with this so any help will be much appreciated.
CharlieI think I have got what you need. The following is the cactus test class that test the getCountries method in my session ejb:
public class WebinUtilTest extends ServletTestCase {
private CacheAccess globParCache;
public void setUp() throws Exception {
CacheAccess.defineRegion("DatabaseDataCache");
globParCache = CacheAccess.getAccess("DatabaseDataCache");
globParCache.defineSubRegion("country");
Attributes cAtt = new Attributes();
cAtt.setLoader(new CountryCacheLoader());
CacheAccess globCountCache = globParCache.getSubRegion("country");
globCountCache.defineObject("countriesDto", cAtt);
globCountCache.preLoad("countriesDto");
globCountCache.close();
globParCache.close();
public void testGetCountries() throws Exception{
WebinUtilLocal wuLoc = HomeFactory.getWebinUtilLocalHome().create();
String[] countries = wuLoc.getCountries();
assertTrue(countries.length >0);
public void tearDown() throws Exception {
if (globParCache != null){
CacheAccess gCache = CacheAccess.getAccess("DatabaseDataCache");
gCache.destroy();
When I run this test here is the stack trace I am getting (in order):

Disabling the object cache for value OciObjects
Hi.
I have a program using OCIObjects as value objects to pass data from OCI to PL/SQL procedures. However in a multithreaded test there is a lot of mutex blocking occuring within the oracle client library (on OCIObjectNew, OCIObjectFree and others), which i am guessing is associated with the OciObjects being managed within the object cache.
Is it possible to disable the object cache? Or maybe construct the value objects in such a way that they are ignored by the cache.
Thanks for any help.Hi,
thanks for your response.
I did consider using OCI_ENV_NO_MUTEX but i would like the oracle OCI library to implement mutexing because i am assuming it does it efficiently and only where required. However it is not clear to me why mutexing would be required when creating/deleting value OCIObjects. I'm guessing it's because of the object cache. (The documentation doesn't explain.) -
Is it possible to disable object cache globally i.e. any deref results in update from db ?

RIMODINI for CIF Object: [MRP Area Matl, MRP Areas]
Hi Experts,
We have Material maintained at MRP areas in R/3. Integration model is maintained with CIF object : [MRP Area Matl, MRP Areas] to bring the new material master at MRP Area changes through Delta mode(CFM3), but the changes to existing material in Integration model at MRP Area does not come over immediately to APO and not through DELTA mode.
We have to execute Report: RIMODINI to bring the changes of existing material master changes at MRP Area level to APO. Since its a performance intensive it takes too long to execute to bring changes over to APO.
Is there alternative method of bringing the existing material master changes at MRP area level for CIF object : [MRP Area Matl, MRP Areas] to APO without executing RIMODINI.
Additional Information: R/3: SAP_APPL 470 0030 SAPKH47030

Thanks,
K sendil KumarHi Sendil,
Are you getting this error only for Material or other master data also?
Please can you quickly check below mentioned checks:-

Proxy.cfg [Object Cache] section
In the [Object Cache] section of Proxy.cfg I have questions on two parameters:
cut thru no CLH length - The default is 51200 (Proxy Console #63) but Craig's Proxy.cfg sets it to 0. TID 10063926 talks about this but I wonder if this problem isn't fixed in NBM 3.9 SP1 and therefore doesn't need to be set to 0 now? Other TID's (10075563, 10069305 for instance) talk about setting it to 5120. What should be the correct setting for 3.9 SP1?
disk management factor - the default is 400 (Proxy Console #63) but Craig's Proxy.cfg sets it to 4000. Can someone tell me what this does and why it should be set to 4000 instead of 400?
thanks,

OK - this is not something that is in proxy.cfg at all. These are
settings in NWADMN32/iManager. For instance, the max hot nodes @ 7000
is a default value that is too low for busy servers. (Recommended is
50000). This sounds like you have not configured the server per the
proxy tuning tid, or my BMgr books.

Find the parameters in NWADMN32 (or iMan in BM 3.9) and check the help
there. Also see the proxy tuning tid.

It seems odd at the moment - I've not really looked into it. I know
that when the proxy.cfg setting came out, it fixed a lot of problem
sites at the time. I've left it at the setting which worked for the
time.

Got it, Craig. I did forget to update some of the settings for the Proxy Cache in iManager. I'll leave the cut thru no CLH length at 0 for now.

With a cache loader, the Java Object Cache automatically determines if an object needs to be loaded into the cache when the object is request.
Can someone tellme how exactly this works.
I am trying to get the cache framework to load objects automatically in the cache.
hwoever unless i explicitly use the CacheAcess.put method. the object is not loaded in the cache.
Plss lemme knw, how the framework does it automatically.
Regards,
MuktaHi Mukta,
FYI, This discussion forum is all about Web Cache, and not related to Java Object Cache.
Anyways, to hint you on automatic loading of objects -> use the CacheAccess.preLoad() method.
You can post this question in a forum related to the Java Object Cache, for better answers.
