Maximum number of members in ASO outline

Hi All,
We are using Essbase 11.1.2.1. We have ASO cube with 11 dimensions, 1 dimension is expected to have more than 30 million members. Is that allowed ? What is the maximum limit for members in ASO cube ?
Also how to improve performance for such cube ?
Kindly advice.

I believe the answer is no. The maximum number of members is 20 million: http://docs.oracle.com/cd/E17236_01/epm.1112/esb_dbag/frameset.htm?limits.html#limits_8

Maximum number of members in a dimension in ASO 11.1.2.1

Hi all,
Is there any limitations on number of members in a dimension in ASO 11.1.2.1?
Also can we predict the maximum number from the 64 bit theory as described in the DBAG?
I guess the maximum must be more than 20 million which I believe was the limit in Essbase 7.
We are working on an application for customer analysis where number of customer will be much more than 20 million.
Can anyone tell me what is the maximum number of members they have seen in one ASO dimension?
Thanks.

Hi Rav,
Is it somewhere documented about the limitation of 20M members? What I see in the dbag page 34 of chapter 62 is "64-bit Dimension Size Limit for Aggregate Storage Database Outline" where it says maximun bits for a leaf member can be 64 and bits are determined by log2(no of members). From this calculation, number of members can be lot higher. Please let me know if this 20M member limitation is documented somewhere.
Many thanks.

Maximum number of members in a dimension (BSO)

we are designing a new planning application and the requirement for one of the dimensions may force us to have a large number of members. I needed a ballpark figrue on what the maximum number of members should be in planning for it to work in an acceptable manner (aggregate times, run time calculations etc) ... the number we are looking at is over 30,000 members and another 15,000 shared members 10-11 levels deep. If any one has experience with such large dimension, can you shed some light on how long the aggregation times would take and if we use it in form, how best to agg the RTPs for that dimension? thank you in advance.

Multiple shared members in ASO outline

 I am building an outline with one primary and three alternate hierarchies within one of the dimensions of an Aggregate Storage (ASO) cube. All of the leaf members in each of the alternate hierarchies are shared members of a member in the primary hierarchy. The non-shared member is a leaf in some cases and a summary point in others. All hierarchies are stored. When I try to save the outline, I get a long list of verification errors. For the stored members to which the shared members refer, Essbase is complaining that "This member has multiple copies of same shared member in at least one stored hierarchy. See other messages for which members and which hierarchies." For the shared members, Essbase complains that "Aggregate storage outlines only allow a shared member once in a stored hierarchy." For the alternate hierarchies, Essbase complains that "This stored hierarchy has multiple copies of same shared member. Remove extra member or change hierarchy to be dynamic." However, I did a find on a handful of the members that Essbase was complaining about and in all cases have found only one instance of each shared member in each alternate hierarchy. The same shared member might appear in two or more alternate hierarchies, but I have not found a case where it appears more than once in the same hierarchy. I have also ensure the following: <UL>The primary hierarchy occurs first in the outline, so non-shared members always appear before any instances of any of the shared members.</UL> <UL>There are no shared members in the primary hierarchy.</UL> <UL>All members, non-shared and shared, are in the same dimension.</UL> <UL>Non of the stored hierarchies contain both a non-shared instance and a shared instance of the same member.</UL> I have tried making the alternate hierarchies dynamic, but query retrievals are so slow that they're completely unacceptable to the client. Has anyone encountered a similar problem? Is there a solution to this? 

I heard back from Hyperion Tech Support again. Turns out it's not a defect after all. It's actually a subtle technicality in the restrictions on shared members with ASO. The first restriction, which is explained in the outline verification error message, is that you can only have one instance of a shared member within a given stored alternate hierarchy. The second restriction is that you cannot have any shared members within a given stored alternate hierarchy where the non-shared instances of the members are ancestors/descendants of each other. Unfortunately, when this restriction is violated, EAS gives the same error message as it does for the first restriction, so it's a bit harder to debug. Hope this saves someone some grief. -Silvester

Maximum number of members in a dimension

Hi,
Is there a limitation of number of members in a dimension in Oracle Olap?
Thanks,
Krishna

I think you got answer for this, which I'll post here for the benefit of other viewers:
"There is no hard limit on the number of members of dimension in Oracle OLAP. You may run into some practical limits based on your HW and cube design, but that won’t be until you’re dealing with dimensions in the multimillion member range."
Say you have a dimensions of 2 million values and another 3 dimensions with 1000 values each. Potential size of the cube if full of data is 2,000,000 * 1000*1000*1000 which make it big. Say you have a couple more dimensions 10,000 and 10,000 ..even bigger.
Compressing the cube to make sure its as small as possible, where patterns of null cells are not stored is good practice most of the time, especially great when there are lots of null values when there's large dimensions. Partitioning and general good modelling are also key. See the OLAP User's Guide for more information.

Maximum number of members in 6.5 outline

Hi, Could anybody tell me, what is the limitation ofnumber of members in Essbase 6.5 outline? Thanks.

Maximum no of members in Essbase Dimension can support

Dear All,
I am using Essbase 11.1.2.2 (64-bit)
Number of dimensions used in my BSO Essbase cube is 9 (4-dense and 5 sparse).
I am having a Customer dimension (sparse) upto 7 levels.
The number of members in customer dimension is 98000.
After loading data in essbase BSO cube, while performing Ad hoc Analysis it throws the following error in Smartview,
"Request timed out contact your administrator to increase netretrycount and netretryinterval"
After making changes to below variables in registry and essbase.cfg files
NETDELAY 500
NETRETRYCOUNT 400
Registry settings
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]\
ReceiveTimeout=480000
KeepAliveTimeout=180000
ServerInfoTimeout=180000
and also with
ReceiveTimeout=900000
KeepAliveTimeout=300000
ServerInfoTimeout=300000
I am getting the following error
"Concurrent requests on the same session are not allowed. Wait till the previous request completes processing"
After i reduced the no of members considerably in Customer dimension, the issue got resolved.
My question is "Do we have any limitations in maximum no of members in a single dimension"
What is the maximum no of members a Essbase dimension can support ?
Regards,
Tharik

To answer your specific question, the limits are listed here: http://docs.oracle.com/cd/E26232_01/doc.11122/esb_dbag/limits.html. According to that, BSO will handle 1,000,000 members.
My question would be what exactly you are doing when the error occurs. Does it happen when you attempt a drill to level zero for example? Or as soon as you retrieve an ad hoc sheet?

Add unidentified members to Essbase outline automatically on load

We are using FDM to map and import data files to Essbase. Due to the number of members in each Essbase dimension, and since all of the source members are identical to the target members, most of the FDM mappings are taken care of by single "like" mapping for each dimension, in order to map the data file members straight to the Essbase members (map source member to target member):
Rule Name: ALLACCOUNTS
Rule Desc: All Accounts
Rule Definition: *
Target Accounts: #Script
Script: Result=varValues(13)
However, if the source system has had new members added but Essbase has not, the load will fail since Essbase cannot locate the new members.
Is there a way to get Essbase to automatically create new members (under a designated parent in each dimension) if they are found to be present in the data file, but found missing in the Essbase outline? This may be a question specifically for the Essbase Forums, however since we are loading from FDM this must be a scenario experienced by others? If the above is not possible (I imagine this is quite likely) what would be the workaround?

FDM is focussed on loading data not metadata. I wouldn't try to automate this, there should be a business process for this that uses a more appropriate toolset (EPMA, ODI etc) to do this i.e. have a seperate metadata update process based on the content of the source files that runs prior to any data load processes.

What is the maximum number of contacts in a group that will send in an iCloud email? I'm sending from MacBookPro.

What is the maximum number of contacts in a group that will send in an iCloud email? I'm sending from MacBookPro.

Limits on Sending Messages
iCloud has several safeguards to ensure that only iCloud members can send messages using the iCloud outgoing mail server. Among these safeguards are reasonable limitations on:
The total number of messages you can send each day (200 messages)
The number of recipients to whom you can send each day (1000 recipients)
The maximum number of recipients per message (100 recipients)
The size of incoming and outgoing messages (20 MB)
You can send 10 emails to 100 people each in a day, for example, or 198 messages with, on average, 5 recipients (and five ninety-ninths).

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.

Nokia C2-01 Help- Maximum Number of Notes Allowed

Dear Members and Support,
Please help me out. I wanted to buy Nokia C2-01 but i wanted to know what is the maximum number of notes allowed. Is it restricted to 15 (or something more) or unlimited notes are allowed.
Help me make a confident purchase
Regards,
striker

I didn't know there is limit on notes. As per my knowledge the limit is there only in basic phones and in these its based on the amount of phone memory available

HT204053 The maximum number of free accounts have been activated on this iPad - what to do??

In trying to sign in to my iCloud account on a new (to me) iPad, I get the message that "The maximum number of free accounts have been activated on this iPad".
Anyone know the resolution to this issue? The iPad previously belonged to two other staff members and now won't let me use iCloud.
Thanks!

Welcome to the Apple community.
Unfortunately, once all your ICloud accounts have been used up on your device, you cannot create any more, no matter what you do. You will need to either reuse one of the accounts you have already created or use another device to create your account.

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?

ORA-00020: maximum number of processes (%s) exceeded

nobody was able to log into the database. when I tried 'sqlplus / as sysdba' I got : ORA-00020: maximum number of processes 1000 exceeded
database is 11.2.0.2 with patch 12
I've bounced the database and increased the processes..
my question is.. is there a way to tell what the processes were? what machine they were coming from? in a log somewhere..
Since I was unable to log in, I couldn't tell what had happened.. who was causing it..
if it happens again.. is there a way to log it?
also, this machine has DataGuard to a standby system.. is it possible for something to go wrong with dataguard and cause this?

>

You have only treated the symptom and not fixed the cause. As fellow members said, you could kill some "non-critical" processes and log in to the database.
But you will have to find out why there were so many processes in place. I am sure you might have set the definite number of processes after your planning before you went live. If you suddenly see too many processes, you will have to find out why and where they are coming from. Also check if there are any rogue processes.
To find out if there are any processes which have no sessions attached
select spid from v$process where addr not in (select paddr from v$session);
To answer your question, data guard shouldn't be affected by this. Nor would dataguard cause this issue in primary.
Fix this processes issue before it's too late. Otherwise, there will be a situation when you will have to keep increasing the processes until you hit the OS limit

As Glen aready noted, the limit is nine for data stacking (StackWise). 3750-X power stacking (Stack Power), between stack members, is limited to 4.
Also note, large 3750 stacks can sometimes be very sluggish doing some CLI commands.
And also note, although StackWise Plus supports "spacial reuse" for unicast traffic, large stacks might congest the ring sooner.
Lastly, for very large stacks, a chassis might be a better and/or less expensive solution.
