How many physical standbys can be created in one data guard environment?

Hi Experts,
How many physical standbys can be created from primary in one data guard environment? Why LOG_ARCHIVE_CONFIG limits up to 9 unique database names? Thanks.

Post the source of your information abouit the limit of 9 names.
Even the Oracle doc shows 1..30 names in the same provided although that doesn't necessarily indicate a limit.

At max how many logical columns can be created in RPD

Hi All,
At max how many logical columns can be created in RPD. I have a requirement of creating 200 columns. Will there be any problem .
Is there any predefind number of columns for RPD creation??
Please help ..

Hi Annapurna,
There's no limit that I'm aware of or which is mentioned anywhere. Just as an example: I have a logical fact table with around 750 logical columns (>500 original measures & 250 derived measures). No issue whatsoever. Opening the presentation table through answers takes about 2-3 seconds (the NQSQL command has a lot to retrieve), but that's about it.
Cheers,

How many server nodes can you create per instance

Hi,
Very often the bottle neck in a java installation (NW04s) is the heap size. In order to increase the heap you simple create new server nodes.
My question is:
How many server nodes can you create per instance?
Is there an upper limit before you have to create a new dialog instance (with a web dispatcher)?
I can imagine that when you create a new server node you also have to increase the heap and max therad of the dispatcher. Is there any upper limit of the heap size of the dispatcher node ?

Rasmus , I think you laid out a real good scenario for every one to contribute
I may be very late but just updating this forum for benefit of everyone who visits this.
In addition to all the points above one must also consider following things if one decides to add more server nodes to one dispatcher
1.Garbage collection time
2.Dispatcher would keep on sending request to node S2 if it is not completely bad and there by impacting all the servernode so you might end up restartiing the entire cluster.
3,Debugging also becomes diffculy as you are not sure on which server node you are within the cluster.
4.If you have something like F5 which does hear beat monitoring even one server node goes bad F5 will not report anything.
So in my view one server node per dispatcher is an ideal configuration.
Over All Dispatcher does not consume more resouces (Disk Space + CPU + memory ) at the same time it will give you maintenance flexibility.
Nothing is right or wrong ,all these things are based on how your infrastructure set up is.

How many apple tv can I connect with one account?

how many apple tv can I connect with one account?

there are 2 recent posts that suggest issues over 5, one where someone was trying to troubleshoot for a friend or client as they couldn't keep more than 5 connected, and the other where somone had more than 5 but was using 2 separate itunes libraries to share the load - not sure if that was with the same or differing AppleIDs.
I guess there is always the possibility that things kight vary from one itunes version to the next even unintentionally to allow more.

How many 7920 phones can be supported on one Cisco 1131AG access point?

hi all,
who knows that how many 7920 phones can be supported on one 1131ag AP? Thanks a lot...

Hi Alomar,
Hopefully this info will help;
Number of 802.11b Phones per AP
Before any discussion about network planning can take place, it helps to understand the basics of the overall network capacity.
The following network capacity guidelines apply to sizing the Wireless IP Telephony network:
No more than 7 concurrent G.711 calls per AP.
No more than 8 concurrent G.729 calls per AP.
Note These design recommendations assume that Voice Activity Detection (VAD) has been disabled on the Cisco 7920 Wireless IP Phones. Use of VAD on the Cisco 7920 phones can conserve bandwidth, but Cisco recommends that you disable VAD on all Cisco CallManager servers to provide better overall voice quality.
In addition to determining how much bandwidth is needed for an 802.11b VoIP call, you must also consider overall radio contention for a particular RF channel. The general rule is that you should not deploy any more than 20 to 25 802.11b endpoints per AP. The more endpoints you add to an AP, the more you reduce the amount of overall bandwidth and potentially increase transmission delays.
The maximum number of phones per AP depends on the calling patterns of individual users (based on Erlang ratios). Cisco recommends no more than 7 concurrent calls using G.711 or 8 concurrent calls using G.729. Beyond that number of calls, when excessive background data is present, the voice quality of all calls becomes unacceptable.
From this doc;

How many maximum records can be stored in One IDoc

Hi experts!!
                   Please let me know what is the maximum capacity of an IDoc. i.e.,
How many maximum records can be stored in an IDoc?
ex: abc,9807,bangalore
      xyz,8976,mysore....... here two records are thr...if u have one lack records like this can we store all the records in one IDoc,....
Thanks in advance,
Sunil K Shetty

Hi Sunil,
Idoc structure is
1. Control record,
2. Data rord,
3. Status record.
1.Control record: contain only who is sender,who is receaver, /which type of data,Idoc number.
   IT store the all control records in one table: EDIDC
2.Data Record: it contains the data records.(multiple records)
It stores the data records sre stored in one table: EDIDD
3.Status records: It show the stutus of the record. (It is multiple)
   The status records are stored in one table: EDIDS
Rewords some points.

How many users/ schemas can we create in an oracle database?

How many users can we create in an oracle database? Or how many users can oracle handle?
Problem-
I have to store information of ontologies (I will use countries instead) in db.
I have to store information regarding countries.
I have 13 tables in all to maintain for each country.
Now there are two approaches:
1) keep only 13 tables. Have an extra column in each table to indicate that a particular
row stores information for which country.
2) create a new user/ schema for each country. So we can get rid of the extra column
needed in 1st approach.
I have used the second approach. This is because number of entries in each table for a
given country will be large.
So initially when the s/w is installed I create a central-user. Each time data for new
country has to be entered central-user creates a user/ schema, and creates tables for
this user/ schema. The central user can access the tables of all the countries by
country_name.table_name. By this approach I believe searching would be easy.
If there is any flaw in my approach kindly mention it.
Thank you

There is no (practical at least) limit to the number of users & schemas you can have in Oracle.
Your approach, however, is not going to scale nearly as well as the first option you outlined (adding a column). You are going to end up caching every possible variation of the various queries you're going to be executing because you will be referring to so many different tables, which is going to mean that you are doing a lot more work to parsing statements and generally churning through the shared pool. If you create enough users, you're liable to start hitting ORA-04030 errors because your shared pool is so fragmented.
Additionally, you're likely going to end up with a whole lot of dynamically generated SQL to accommodate new schemas getting added over time which is going to cause you even more pain. Figuring out dynamically what table to join in is a heck of a lot more difficult for the programmer to write and for the database to handle than simply passing in a different country code.
If you're concerned about having too much data, you can have your cake and eat it to by adding the country column and partitioning the tables based on country.
Justin
One other item I forgot to mention is maintainability. Having dozens or hundreds of "identical" schemas makes maintenance a huge pain because something like adding a new column now requires dozens or hundreds of separate DDL statements. You're almost guaranteed that some schema isn't going to be in sync-- it's going to miss a column or miss an index, etc.

How many softMotion references can you create on an Interface Object

I'm wondering how many softmotion references I can create on an interface object. For example can I create a straight line move on an axis, keep that reference open then at the same time create another line move referece on a coordinate space that using that same axis?
Can I have multiple line move references open at the same time on the same axis?
Thanks,

Thanks Paul,
I have noticed that the SoftMotion express vis open a reference on first call, but they never close the reference. On my machine I will be doing regular coordinate moves and from time to time I will need to perform an Axis move. Would it be better practice to close each reference after I perform the move? How much overhead does it take to create a new reference? The thought I had on keeping multiple reference open was to minimize the overhead in opening a reference. Once my system gives a trigger to perform a move, I need it to be very responsive.
Thanks,

How many Apple TVs can you have on one iTunes account?

Just wondering how many Apple Tvs I can put on my iTunes account. Already have one in the living room and I was looking to put one more in the bedroom.

That would be fine.

How many apple TVs can you have on one network 5, 10, 15, infinite?

I have an application where there are many rooms and I would like to be able to use Airplay in each room, can I buy 10 or more Apple TV units and put them all over my house on my wireless network and be able to airplay to any one of them? What is the limit of Apple TVs that I can have in one area. Has anyone tried this? How many have you maxed out at? What is the limitation?

There is no specified limitation but you will encounter a practical one. It will be a function of the numerous and generally unpredictable variables that affect any wireless network.
Ten Apple TVs is certainly within the realm of possibility though. This post reports success with fifteen of them.

How many hard drives can i stream from one mac for apple tv

Hi a newbie to all this ive got a 500gb external hd and running out of space but am looking to buy a 1tb but i want to set it up as im using both hard drives so i get 1.5tb as this is a cheaper option for me is this possible and how
many thanks for your time

You need to turn off the option to copy content to the iTunes folder in iTunes preferences, then when you add new content to iTunes you will need to place the content on one of the HDDs and then drag and drop it onto iTunes from a finder window.
Or you can alternatively leave the "Copy" option on and simply press the Alt-key when dragging and dropping content to momentarily suspend the "Copy" of the dragged content to the library. (I.e., iTunes will gladly manage both copied and non-copied content as long as you do not move or delete the non-copied files at the Finder level after adding them to the iTunes database.)
