Maximum number of instances
Hello everyone,
I just want to ask if there's a limit/maximum number of workflow instances for
a specific workflow label/identifier? From what I know, the label is just a label
for the user to identify the instances but it's not really a unique id for an
instance. So, many instances can have the same label but they are actually unique
from one another.
I'm asking this question because I'm having a bit of a problem with my workflow.
I'm using a particular label many times and WLPI creates many instances. But after
some time, it seems to stop creating new instances for the same label. Has this
happened to anyone else before? If so, how did u resolve it? If not, do you have
any suggestions how to go about this?
Thank you very much!
Hi shannon,
I'm using WLI 7.0 sp1.

The answer would be that as many as the server's ram would hold up . There is no limitation otherwise as such. How many maximum you have created so far?

Maximum number of database instance on Exadata V2
Does any body know maximum of database instance can starting on Exadata V2, haft rack configuration. I can start only 13 instance but when start instance 14 it failed. I had try to increased number of semaphore but still not work.
I would expect that the maximum number of instances would be covered by sanity rather than something Oracle has configured.
Given that you've not posted the actual error message my recommendation would be that you either provide us with a lot more
information or that you open an SR with MOS.
Please also explain how you came to the presumption that the issue was semaphores. -
Max number of instances per Server
Good morning,
I've installed Oracle9i in a Windows 2000 Server with 1GB of memory. After that I've created several instances of Oracle DB. With 3 instances my server works acceptably, but after adding two mor instances I've begun to have some perfomance problems and the access speed has considerably decreased, so my question is, what is the maximum number of instances that the same Oracle server can support in order to optimize the access to the DB?
Thanks in advance.
IsabelHi,
I am confronted with a similar problem. ie, we have got several instances on the basis of one application/one instance. I am asked to regroup all these instances to one and only one instance containing several schemas to reduce the number of servers, number of instances and on the way reduce the administrative ( dba ) tasks. As i have got some knowledge of dba, I thought of installing this instance under Oracle 10g like this : an application on its own tablespace and the backup of this tbs via rman. So when an application crashes, I can make use of TSPITR to bring the database to its initial ( stable ) status. My questions are :
1° any re-initialisation of the database will sanction all the schemas. Is there any
way to avoid this ?
2° as different tablespaces be brought to a consistency status different in time via
TSPITR even if the controlfile happens to be the same ?
3° if I opt for UNDO management AUTO, there can be only one UNDO TBS
active at a time. As this won't render me to trouble when i need to recover
only one application ? or on performance ?
Any prompt reply will be greatly appreciated.
Best regards.

Max number of instances for stateful session beans
Hi,
I am using OC4J 9.0.3 which is embedded in JDeveloper. I would like to set the maximum number of instances for stateful session beans. I know that the session-deployment section of the orion-ejb-jar.xml file has an attribute called max-instances, but it only works for stateless session beans. (at least it says so in the documentation and it did not work with my stateful session bean)
Anyone knows how to do it?
Thanks,
Leonardo PenhaLeonardo -- Stateful session beans do not come from a pool but are assigned 1 bean to 1 user. When the EJBs life ends the bean goes away. If what you are asking about is passivation configuraiton then that is different. We currently do not support passivation based on some count of SFSBs that exists inside the container but we will provide that capability in the next release of OC4J. (Note: When passivation occurs is mostly up to the vendors and it is not required by the J2EE 1.3 specification based on performance metrics. What is required is that when a SFSB is passivated it is done correctly and we do that.)
Thanks -- Jeff -
Hi All,
Is there any function to find the maximum number .For instance I have 10 numbers.Can I find the maximum number out of it using any function ( Not function module ).
Regards,
Vishu.Vishwanath,
sort and then display the last number. Small example.
REPORT zforum140 .
data : begin of itab OCCURS 0,
data1 type c.
data: end of itab.
data: n type i.
do 5 TIMES.
n = n + 1.
itab-data1 = n.
append itab.
enddo.
sort itab by data1.
n = itab-data1.
write:/ n.

What is the maximum number of characters in an Oracle 10G Instance Name
All,
Can I know what is the maximum number of characters in an oracle 10g instance name under AIX? Is it 7 characters or 8 characters?
regards
SanthoshOne should really make the difference between db_name and instance_name: if instance_name default value is db_name it can be different
(even on a non RAC database).
For example with Oracle 10.2.0.4 you can create a database named DB78 with instance_name=DB12345678:
$ uname -a
Linux lx01.localdomain 2.6.18-92.el5 #1 SMP Fri May 23 22:17:30 EDT 2008 i686 i686 i386 GNU/Linux
$ ps -fu oracle | grep smon
oracle 6353 1 0 20:30 ? 00:00:01 ora_smon_DB12345678
oracle 6412 5596 0 20:37 pts/1 00:00:00 grep smon
$ export ORACLE_SID=DB12345678

Maximum number of VPLS instances on ME3600X box
Hi,
Does anyone know what is the current maximum number of VPLS instances on ME3600X (Advanced Metro IP Access license)? I've found on one of the old presentations that this was only 26. And why is this limitation present?
Best regards,
KrzysztofHi Ricardo,
as for every platform, in the official limitations and restrictions there is a margin of prudence in what the platform can support. Let's say you can configure 40 VPLS instances (never tried) on your 3600X , and you do it with no apparent issue, this implementation would simply fall off the tests which Cisco did on that particular platform. Hence, any bad subsequent behaviour would not be "Cisco fault" and i actually see no reason for doing that.

Maximum number of Oracle-10/11 instances on a Windows server?
Hi,
What is the maximum number of oracle 10/11 database instances that can be installed on a Windows-32 server.
Also what is advisable?
Assuming each database instance will have no more than 4 concurrent users with light usage.
Windows Server - 2008 4GB Ram Xeon or similar processor.
Many Thanks

You can have any number of instances installed on the server. 42 is a great number.
Just don't turn on more than one or two instances at a time.
Better might be to look at, and understand, 'schema' concept - it may be possible to use multiple schemas in one instance/database to accomplish the same thing as your multiple instance proposal. -
ORA 01792 maximum number of columns in a table or view is 1000
Hello every1, I wish to register a large xmlschema doc, I am using the command
begin
dbms_xmlschema.registerschema(
schemaurl=>'xxxx',
schemadoc=>bfilename('XMLDIR','xxxxxx.xsd'),

end;
But the schema file exists 1000 col and it gives me the error msg of

ORA-20001: Maximum number of email messages per workspace exceeded
Greetings. We are running APEX 4.1.1. I have an application where we have to send out email messages to a list of emails. Currently there are 2469 email addresses. Originally we put the email addresses in the BCC but we received an error that we had exceeded the size limit of the BCC. So we modified our procedure to send one email at a time, in a loop.
Now we are receiving the following error message:
"ORA-20001: You have exceeded the maximum number of email messages per workspace"
Has anyone else run into this issue? What is maximum number or email messages per workspace? Is it a limit per day, per session?
We have not added emails to this table since last year, so the maximum number of email messages allowed may have changed recently?
I did find this Forum post that addressed the issue but no one responded:
How many mails i can send at a time per day using APEX mail system?
Thanks,
JohnHi jfosteroracle,
You are getting the error may be the following reason,
Check the following,
Login as ADMIN and Goto -->Manage Instance-->Instance Settings--> Mail-->Maximum Emails per workspace
Actually this number denotes the Number of mails can be sent per 24 hour for the workspace,It may exceeded.
It may be the reason.
Thank you.
Regards,
Gurujothi

Thanks for your reply!Hi Pig,
When i run my web-application with the embedded OC4J server, the following error message is prompted:
java.lang.Exception: ORA-00020: maximum number of processes (150) exceeded

void com.evermind.server.http.HttpRequestHandler.run(java.lang.Thread)
void com.evermind.util.ThreadPoolThread.run()
Question:
- What is the cause of this error message? How to avoid?.
From the Oracle error message documentation:
ORA-00020 maximum number of processes (string) exceeded
Cause: All process state objects are in use.
Action: Increase the value of the PROCESSES initialization parameter.
Another alternative approach may be to configure your Connection pool and/or your ApplicationModule pool to optimize the use of
database connections and/or restrict the number of database connections used by the application. For example, if your application
has declared many root ApplicationModules (i.e. more than one ApplicationModule pool is in use) then it may help to enable the
jbo.doconnectionpooling switch so that each ApplicationModule instance in the pools does not maintain a dedicated database
connection while not in use. Another alternative if you are using the BC4J connection pool (not a JDBC datasource) may be to
restrict the number of connections the pool can create to < 150 with the jbo.maxpoolsize switch. However, please note that this
may have an impact on throughput.
- I intended to deploy my application to 9IAS server. Will the same problem occurs too?.
This is a database issue. So, yes.
Hope this helps.

Maximum number of services for Oracle 12c
can someone please give me a hint where I can find the limitations for number of services on Oracle 12c?
In the reference guide I found: maximum number of services per instance = 115
But that cannot be true because you can have up to 252 pluggable databases per database and each one is associated with a dedicated service.
If done some trials and currently I'm at 556 services. But I cannot find a document with the exact maximum.Hi Friend,
Two Types containers are available in Oracle Database 12c
1. The ROOT container - - > This is first container and mandatory container.
2. Pluggable Database Container - - - > This is the container for application
So, Limit is - - > 253 PDBs in a One Container Database (CDB) it includes the SEED also and Services are 512 in a Container Database (CDB).
Check the following query to know the number of services
Select name, pdb from cdb_services;
Hope it helps...
Thanks

I am stuck on this. i have changed the value of processes in init.ora, but this error still exists. i think I need to do: create spfile from pfile='init.ora', but I need to log in to do, but I can't log in sys.
Please help.
Thanks.i forgot shutdown abort. used that, created spfile from pfile, and it works ok now.
