Coherence "out of process" topology question
Hi,
We consider using Coherence as a distributed cache (messaging) in out product
As far as I can understand from Coherence's whitepapers the only option to use an out of process cache (a dedicated process for the coherence )
Is by using Coherence*Web which is actually a web session cache, and doesn't fit our needs for messaging cache.
My question is , Is it possible to use "out of process" cache in the standard edition of Coherence ?
Well, another way would be, to setup a dedicated out-of-process Cache server/cluster (outside of
your application server) & then connect to it from your code (deployed in your application server).
The only way for your application server deployed code, to access an out-of-process remote cache
server/cluster (which is running outside of your application server) would be, by way of using
Coherence*Extend.
Your application server deployed code would internally use the 'client' library of Coherence*Extend,
whereas the remote cache server/cluster would internally refer to a 'server' library Coherence*Extend.
Please see Chapter 17 (Configuring & Using Coherence*Extend) in Coherence Developers Guide
for more info.

OSB result caching with Coherence Out of process
Existing setup:
Oracle Fusion Middleware SOA 11g domain with
1 weblogic cluster
1 OSB cluster
We have an Out of Process Coherence cluster configured with caches defined already which is just working fine in production.
The requirement is that development team would like to use the OSB result caching feature and we are having hard time to configure this OSB result cache join our existing cluster.
Any suggestions on this is appreciated.Hi,
You would need to override the operational configuration on OSB Server to join the cluster spawned by the Coherence dedicated servers. Also, set the flag -Dtangosol.coherence.distributed.storage=false in the ServerStart of your OSB Servers which will disable the data storage in the OSB Servers.

Out-of-process Coherence server (OSB)
Hi,
Iam trying to set up a seperate coherence server , i.e not the default coherence cache supported with weblogic (Fusion middleware server).
I started the coherence server setup on seperate machine(jvm) and followed the steps to integrate the out-of process coherence server with OSB /weblogic server.
But the application deployed is still storing data to the deafult cahe provided by the OSB(weblogic) server.
Can any one help me with the steps to integrate OSB/Weblogic server with external Coherence/Cache server.
Thanks,

Sorry if the title is vague, I am unsure how to properly word my question down to a single line. Anyways, on to my question, if I have two 16 core processors in a server, but I have 1 virtual machine that is setup with 4 cores, will the vmware only use 4 of the physical cores, or will the processing be distributed among all the cores? If searched the documentation but was unable to find much information about this specific situation. The reason I have it set to 4 cores instead of more is because the application I am trying to run only uses up to 4 core and if I can use vSphere to distribute out that processing it would greatly improve the performance. Thank you in advance.
Welcome to the Community - a VCPU can only run on a single core at a time - so your 4 VCPU vm will run only 4 of the 32 cores that are available in you ESXi host but each - the ESXi host is also smart enough not let the any of the 4 VCPUs share core either. By default the VM's VCPUs can be scheduled on any of the 332 physical cores
I am also moving your question to a more appropriate forum. -
Ora-04030 out of process memory
Hai All,
My database is oracle 9i(9.2.0.1.0)in AIX
when I run one query from my oracle developer suite session then 'ora-04030 out of process memory error when trying to allocate 38424 bytes (hash-join subh,klcqc:kllcqslt)'
This same query when I run from sqlplus it works fine.
how this happened ?
Please help...urgent..The problem is in unsufficient memory for a hash join.
The questions are:
- do the explain plans differ, that only one session has this problem
- how do you manage the PGA (auto/manual), what are relevant parameter settings (pga_aggregate_target / hash_area_size etc.)
- do you use shared server - allocation methos differ for this case.
If you use manual pga tuning (or perhaps shared server), then increasing hash_area_size might help. But without relevant info, it's shooting in the dark. -
ORA 04030 Out of process memory error
Dear experts,
I know there are multiple discussions around this error and I have been reading through most of them in the past one week or so, but looks like we are running out of options or are missing the color altogether. Ok, we are getting ORA-04030 - out of process memory while allocating....while one of our batch process runs in the night. It simply tries to insert/update to a table. Our installation is 11.2.0.1.0 with no RAC configuration and on 64-bit AIX having 6 cores, 12 CPUs and 16 GB memory.
We have checked the Workarea_Size_Policy is set to be as Auto so Oracle decides how much memory to allocate to PGA automatically on run-time based on the demand. And based on the AWR report it doesnt look like we are anywhere near the country having a PGA-deficit!! I am attaching the AWR report in a word document here for your reference.
Also attached below are the configurations and the ulimit values.
IKBTRN1> show parameter workarea;
NAME TYPE VALUE
workarea_size_policy string AUTO
oraipeikbtrn1:/home/oracle-> ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 4194304
memory(kbytes) unlimited
coredump(blocks) unlimited
nofiles(descriptors) unlimited
threads(per process) unlimited
processes(per user) unlimited
Now, nothing seems to have contributed to the out of process memory issue from Oracle standpoint. I would be happy to be proved wrong here, if I am wrong.
So, whats going wrong here? A possible memory leak which we cannot zero down to, a OS memory limit or something else?
Seeking expert's advise on this, and also sincerely appreciate your time in looking at this.
Thanks.
P.S - I am pasting the whole AWR report since there is no 'upload file' option here that I can see.

I couldnt add the rest of the report here since it is telling me I have exceeded 30000 characters. If you want to see the full report, please email me at [email protected]Unless your database is strictly a DSS-type of database, your AWR report exposes loads of issues with it. And I think none of the time during the AWR window was spent on database. Look at the DB time (with all those multi cores) compared with the elapsed time of the AWR.
As you are on 11g, why not make use of MEMORY_TARGET (a single parameter to manage both SGA and PGA)? If you are already on it, ignore this as I can't see it anywhere. If not, get rid of SGA_TARGET and PGA_AGGREGATE_TARGET and replace it with a single MEMORY_TARGET parameter. However you may have a minimum threshold set for different SGA pools so that they won't shrink beyond that point.
Having said that, setting MEMORY_TARGET is not a guarantee to avoid ORA-4030. Just a single bad PL/SQL code could go and exploit the untunable part of your process memory and even go and blow up the physical memory. If you are using FORALL and BULK load, see if you can cut it down into few chunks rather than running as a single process.
What does your V$PGASTAT say? -
ORA-04030: out of process memory when using Java Stored Procedures
Hello,
I have a problem using Java Stored Procedures in Oracle 10g.
My Java application performs http posts to a webservice and the response is parsed in order to populate some DB tables.
There is a scheduled job which calls the Java Stored Procedure every x minutes.
No matter of the 'x minutes' values - after about 160 - 200 calls I get this error:
ORA-04030: out of process memory when trying to allocate 1048620 bytes (joxp heap,f:OldSpace)
ORA-04030: out of process memory when trying to allocate 2097196 bytes (joxp heap,f:OldSpace)
The job stops just while is posting the http request. The weird thing is that almost each time the first http post request I get this error:
java.net.ConnectException: Connection refused
at java.net.PlainSocketImpl.socketConnect(Native Method)

and the second try works fine.
So, The out of process memory occured each time just before getting such an error, and I suspect to be a connection between these errors.
Tech details:
1. OS: WinXP
2. Oracle 10.1.0.2.0
3. To perform http post I use HttpClient 3.1 from Apache.
4. I checked the http connection to be closed each time, and this is done.
5. I checked the oracle statement and connection to be closed each time and this is done
6. The JVM error (logged in .trc files of Oracle) is:

Can be a problem with JVM threading under Oracle ?The server prcess failed to allocate more memory for large objects ( in Oldspace).
If you Google ORA-04030, you will see several recommendations to work around this.
The Java VM in the database already has HttpClient, i don't know why you are loading the Apache HttpClient but this might not be the surce of the problem.

I have a Service (.exe) where I was registering for my COM Component like below
CoInitializeEx(NULL, COINIT_MULTITHREADED);
HRESULT hres = CoInitializeSecurity(NULL, -1, NULL, NULL, RPC_C_AUTHN_LEVEL_NONE, RPC_C_IMP_LEVEL_IMPERSONATE, NULL, EOAC_NONE, 0);
if (hres != S_OK)
OutputDebugStringA("Security Descriptor not initialized");
ITypeLib* pTypeLib;
HRESULT hr_1 = LoadTypeLibEx(L"ServiceIdl.tlb", REGKIND_REGISTER, &pTypeLib);
if (pTypeLib != NULL)
pTypeLib->Release();
RegisterServer(L"Service.exe", CLSID_classAImpl, L"ClassAImpl Sample", L"Component.ClassAImpl", L"Component.ClassAImpl.1", 0);
g_hEvent = CreateEvent(NULL, FALSE, FALSE, NULL);
DWORD reg = 0;
IClassFactory *pIFactory = new classAFactory;
HRESULT hr0 = CoRegisterClassObject(CLSID_classAImpl, pIFactory, CLSCTX_LOCAL_SERVER, REGCLS_MULTIPLEUSE, ®);
if (FAILED(hr0))
OutputDebugStringA("classAImpl is not registered");
CoUninitialize();
exit(1);
HRESULT hr1 = CoResumeClassObjects();
if (hr1 == S_OK)
OutputDebugStringA("classAImpl is Resumed Registering");
WaitForSingleObject(g_hEvent, INFINITE);
CloseHandle(g_hEvent);
CoRevokeClassObject(reg);
pIFactory->Release();
CoUninitialize();
From Client Code I am CreatingInstance Like Below
COSERVERINFO si;
MULTI_QI qi;
COAUTHINFO cai = { RPC_C_AUTHN_NONE, RPC_C_AUTHZ_NONE, 0, RPC_C_AUTHN_LEVEL_NONE, RPC_C_IMP_LEVEL_IMPERSONATE, 0, EOAC_NONE };
si.dwReserved1 = 0;
si.pwszName = L"\\\\localhost";
si.pAuthInfo = &cai;
si.dwReserved2 = 0;
qi.pIID = &IID_classA;
qi.pItf = NULL;
qi.hr = 1;
CoInitializeEx(NULL, COINIT_MULTITHREADED);
HRESULT hr = CoCreateInstanceEx(CLSID_classAImpl, 0, CLSCTX_LOCAL_SERVER, &si, 1, &qi);
hr returning error "general access denied error";I think we may run into the limitations mentioned in the remarks of CoCreateInstanceFromApp doc(show as below). If you can provide a repro project, I
can give you more details about what happens.
The CoCreateInstanceFromApp function reads class registrations only from Fusion contexts and manifests, and from the HKLM\SOFTWARE\Classes\CLSID registry hive.
Only built-in classes that are supported in the app container are supplied. Attempts to activate unsupported classes, including all classes installed by 3rd-party code as well as many Windows classes, result in error code
REGDB_E_CLASSNOTREG.
The CoCreateInstanceFromApp function is available to Windows Store apps. Desktop applications can call this function, but they have the same restrictions as Windows Store apps.
If you are trying to call some windows classes in your library, I will suggest you check how to create windows runtime out of process component by viewing
this sample. This is what I usually do.
To be honest, I did not try to implement the out of process COM component using the method you tried as we previsouly do on desktop. I will suggest you try to register a very simple library(like a signle class and single interface which returns an integer),
and see if it will work.

Hi
I have a stored procedure that uses the XMLQuery function (SELECT XMLQuery( '......' RETURNING CONTENT) FROM dual; ) to extract data from 3 different tables and store the xml file in XML DB. This store procedure was running fine for a long time until 2 weeks ago where I started seeing the following error:
Database Error: DBD::Oracle::db do failed: ORA-04030: out of process memory when trying to allocate 92 bytes (koh dur heap d,qmxtkWriteXobToOpn:heap)
Currently I have 16,000 records. I am not sure what is going on, the size of the previous successful output xml file is about 2M. I also noticed when the stored procedure runs with 3G of system memory available, it basically used up all the memory and cpu time. The store proc consistently dies after 3.5 hour and spits out the ORA-04030 out of process memory error.
Does anyone have any suggestion what to look for or what parameters I need to set? ThanksUnless your database is strictly a DSS-type of database, your AWR report exposes loads of issues with it. And I think none of the time during the AWR window was spent on database. Look at the DB time (with all those multi cores) compared with the elapsed time of the AWR.
As you are on 11g, why not make use of MEMORY_TARGET (a single parameter to manage both SGA and PGA)? If you are already on it, ignore this as I can't see it anywhere. If not, get rid of SGA_TARGET and PGA_AGGREGATE_TARGET and replace it with a single MEMORY_TARGET parameter. However you may have a minimum threshold set for different SGA pools so that they won't shrink beyond that point.
Having said that, setting MEMORY_TARGET is not a guarantee to avoid ORA-4030. Just a single bad PL/SQL code could go and exploit the untunable part of your process memory and even go and blow up the physical memory. If you are using FORALL and BULK load, see if you can cut it down into few chunks rather than running as a single process.

Flashback : Error:ORA-04030: out of process memory when trying to allocate
Hi All,
I have executed this query on my db for using flash back features:
select * from flashback_transaction_query where table_owner='USERNAME'
However, it throws the error after being executed for 5 min:
ORA-04030: out of process memory when trying to allocate 268 bytes (Logminer LCR c,krvxbpdl)
Please help me in understading the error and provide some links/docs to resolve this.
Thanks,
KishoreThat's the error description:
What does an ORA-4030 mean?
This error indicates that the oracle server process is unable to allocate more memory from the operating system.This memory consists of the PGA (Program Global Area) and its contents depend upon the server configuration.For dedicated server processes it contains the stack and the UGA (User Global Area) which holds user session data, cursor information and the sort area. In a multithreaded configuration (shared server), the UGA is allocated in the SGA (System Global Area) and will not be responsible for ORA-4030 errors.
The ORA-4030 thus indicates the process needs more memory (stack UGA or PGA) to perform its job.
