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

Maximum number of service in a database?

Somebody can tell me if there is a maximum number of service I can use in a database? Those services are create with dbms_service or "srvctl add service" or dbca. Those services are set in the database parameter SERVICE_NAME automatically by the Clusterware or manually if it is not a cluster database.
Thank,
GG

I would tend to be suspicious just because 50 services is quite a lot. If you really have 50 distinct applications and you want to manage 50 different services, 50 different TNS aliases, etc. you certainly can. But most organizations aren't going to see a lot of benefit from having that many services and may end up spending a lot of time micro-managing things the system unnecessarily.
You would generally have separate services if you wanted to have different services on different nodes of the cluster (i.e. create a reporting service on a subset of the nodes of the cluster for reporting work so that doesn't get comingled with the OLTP workload on the other nodes). It would be rather hard to manage 50 services on the same cluster effectively-- you'd either have all 50 services spread across all the nodes, in which case there would be little benefit to having all those services, or you'd have something like 5 services on each of 10 nodes which would tend to result in poor load balancing (assuming the load profile of each application is rather variable) or lead to constant administrative "futzing" to improve load balancing.

Create standby maximum number of logfiles for each thread

The oracle doc states this equation for appropriate number of standby redo log file groups
(maximum number of logfiles for each thread +1) * maximum number of threads
How do you get the maximum number of logfiles for each thread and the max thread?
Thanks!

If you are running RAC you can, in theory, be running with a diferent count
of Online Redo Logs in each thread (instance).
However, normally, you would have the same number of Redo Logs in each
thread.
The theoretical max is prescribed at the CREATE DATABASE and can be
changed with a CREATE CONTROLFILE. If you do an
ALTER DATABASE BACKUP CONTROLFILE TO TRACE
the sql script in the tracefile shows the maximum number of logs and members.

Maximum number of services

What is the maximum number of services that can be configured on a CSS?

Tim,
The suggested max is a combination of services and content rules not to exceed 300. This has been the development suggested ma for several years now.

Maximum number of items for an FI document ('999') has been exceded

Hi,
I have try to move some materials from one storage location to another using MB1B transaction. And i receive following error:
Maximum number of items for an FI document ('999') has been exceded.
Please someone help me.
Thank you.

Dear Dan
As you would be aware one FI document can have line items upto a maximum of 999 and it seems, you are trying to input more than that and hence the error.
Try to minimise the number of line items and retry.
thanks

How to set maximum number of jobs in oracle

Could pls tell explain me about how to set maximum number of jobs in oracle....
Regd,
Mahi

I don't think there is any limit on number of jobs that can be submitted to Oracle. However, there is a limit on the number of processes that would execute those jobs (governed by JOB_QUEUE_PROCESSES).

Configuring Web Services for Oracle XML DB

Hi all...
I think I need some help one this subject....
We have a 10G Release 2 Oracle single instance ( not RAC) install on a Linux Redhat v5.3 64 bit server. Are developers are user Visual Studio .Net and wnat to send xml files to a web service so that the xml file (containing data) can call a PL/SQL package (to be written) which will take the data out of the xml input file and insert rows into a prefined table within the instance. Now they have browsed the web and have come upon the following links...
http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm
http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb22pro.htm#i1026724
Currently, within the database I looked at the schema XDB and have unlocked the account and connected as the user XDB. There are some 680 objects in the following groups...
SQL> select object_type, count(*) from dba_objects where owner='XDB' group by object_type;
OBJECT_TYPE COUNT(*)
SEQUENCE 2
PROCEDURE 5
OPERATOR 8
LOB 334
LIBRARY 12
PACKAGE 20
PACKAGE BODY 17
XML SCHEMA 25
TYPE BODY 5
TRIGGER 12
TABLE 36
INDEX 51
FUNCTION 5
INDEXTYPE 2
VIEW 2
TYPE 144
16 rows selected.
Now in the links above it mentions that the xdbconfig.xml needs to be altered etc. However, I have searched the entire $ORACLE_HOME and there is no file definition of that description.
From a DBA prospective...what do I have to install on the Linux server? I assume from the Oracle Database 10g Companion Products I need to lay down Oracle HTTP Server in a new Oracle home as the first step...or not? Does the HTML DB need to be installed as well?
And for Configuring Web Services for Oracle XML DB...what else has to be installed? And from what product line?
Thanks in Advance....
Cheers

Hi Marco...
First of all ...thanks for the reply.
I followed the link and the infor in that web page. However, there were a few things that did not work....
1. The http://localhost:8080/ as is brought up a web page withe the heading as
==========
ORACLE DATABASE 10g EXPRESS EDITION LICENSE AGREEMENT..
==========
The other browser test ftp://localhost:2100/
did not find any page?
2. Then I went onto running (as the sysdba) the pl/sql to enable the ORAWSV Entry Service
however it error out. So I did a describe on DBMS_XDB and the function deleteServlet does not appear
then I had a look and this link to > http://www.liberidu.com/blog/?p=471
was for 11G and the other link > http://docs.oracle.com/cd/B28359_01/appdev.111/b28369.pdf
was for 11G.
However, we are on 10G
=================
SQL> select * from V$version;
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi
PL/SQL Release 10.2.0.3.0 - Production
CORE 10.2.0.3.0 Production
TNS for Linux: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
==================
So is there must be other sql for 10G?

What is the maximum number of row for a table control in LabWindows/CVI ?

I use LabWindows CVI 8.5.1 (MMI first developped in version 6.0).
In one of our many MMI, a table control contains a list of aircraft parameters.
We can add as many parameters (row) as we want but over 40 000 we observe a crash of the LabWindows CVI runtime.
Our client want to inscrease the number of parameters (row) up to 200 000 !!!
So my questions are:
What is the real maximum number of row for the table control ?
Is this maximum number of row different on LabWindows 2010 version ?
Or is there an other solution ?
Thanks

Greetings,
Can you clarify what you mean by "crash"? Is there an error message thrown? Is it possible that you've consumed all of the available memory?
Please let me know.

Maximum Number of Characters for Password??

Hello, and thank you for reading my post. I recently modified my Apple ID Password to a very strong password containing 32 characters. When I try to log into this discussions group with that particular Apple ID, I can't because the website won't accept the password? Wouldn't all of Apple's sites accept the same password?
Is there a maximum number of characters for a password in this discussion group?
Thanks

What makes you believe that 32 characters is remotely necessary? As Ralph indicates, a shorter password is equally secure, in realistic terms. Keep in mind that even if some hacker set up a script to repeatedly try random passwords on your account, they're never going to get in because there are limits on the number of times one can enter an incorrect password before being blocked on any decent system. You can have a much shorter password, and as long as a human can't guess it from what is publicly known about you, it's secure.

Maximum Number of Version for a DIR

Hi,
Can anyone tell me the maximum number of versions for a DIR? The field is 2-char alpha/numberic. I assume after it reaches 99 it will start using alpha characters. I am looking for the pattern it will use after 99 and also the total number of versions allowed.
Thank you
Bob Schaefer

Hi Bob,
This depends on the version increment defined in your document type. Version increment "1" is 00 to 99. It will not use alpha after 99... I presume it may give an error or start again from 00 if ver 00 does not exist anymore, but I haven't really tested this out. There several other version increments you can choose from and the number of versions allowed will depend on that. For example version increment "3" is defined as A0 to Z9, therefore this will give you 26x10 = 260 versions.
Extract from the SAP help pasted below will give you a pretty good idea of the possibilities.
Value Description
0 No version numbers
1 Numeric version numbers   00 .. 99
2 Numeric version numbers   01 .. 99
3 Alphanumeric numbers   A0 .. Z9
4 Alphanumeric numbers   A1 .. Z9
5 Alphanumeric numbers   AA .. ZZ
6 AA .. AZ,A0 .. A9;BA .. Z9
7 as 6, but without 0
8 _A .. Z ; AA .. Z9
9 as 5, but 00 allowed
A as 6, but 00 allowed
for USER-EXIT
Hope this helps.
Cheers,
Lashan

Maximum number of participants for MeetMe conference

How do you determin the maximum number of participants for MeetMe conference? All participants will join the conference via the PSTN with the exception of the initiator.

It depends wether you are using hardware of software conferencing resources. With hardware conferencing resources you can have 32 streams per port on a cat 6K blade so you could either have on conference of 32 participants or 10 conferences of 3 participants.
For software conferencing it depends whether the conferencing resources are co-residant on the call manager of on a seperate server. If co-residant the max streams is 48 and 128 for a separate server

Maximum number of logfiles for each thread

Hi all,
When I configure a Standby Redo Log, to determine the appropriate number of standby redo log file groups, I should use the following formula:
appropriate number of standby redo log file groups: (maximum number of logfiles for each thread + 1) * maximum number of threads
My question is: how can I determine the maximum number of logfiles for each thread ? Is it the online redo log file per group? or total of redo log files in all groups?

How can I set the maximum number of restarts for my PDF files?

How can I set the maximum number of restarts for my PDF files?
My software edition is Acrobat X

In the old days when PDFs were only opened on desktops and only in Acrobat or Reader, scripting could fake security features and people were generally convinced. As there are so many ways to open a PDF without scripts ever being run (from mobile devices to in-browser display, or simply opening the file in Illustrator), none of that works anymore.
