For streams_pool_size fine adjustment, the parallelism increases the number of integrated process replicat?

The GoldenGate tuning white paper (http://www.oracle.com/technetwork/database/availability/maa-gg-performance-1969630.pdf) recommended setting based on the integrated replicat process number streams_pool_size.  It says nothing about parallelism, as it does for integrated capture.  If I configure the 4 replicates, use this number in the calculation?  Alternatively, because I want to implement parallelism to 16 for each replicate, I have to use 64 in the calculation?  The latter would make the recommended streams_pool_size 80 GB.

The calculation you are looking for is:

(max_sga_size * parallelism) * 25%

In this example:

(1024 M * 2) * 25% = 2560M (2.5.G)

Your streams_pool_size must not exceed 3.5 G no matter the amount of parallelism.

Do not confuse the parallelism of the database with goldengate parallelism. Goldengate parallelism is defined using the DBOPTIONS INTEGRATEDPAPRAMS options.  If you want you can refer to my presentation to transform the integrated process of goldengate to my slideshare.net (replication extreme at IOUG collaborate 15) site

Thank you

    It depends on how your system is used (number of users.., the number of applications, number of CMs and process, etc).

    You must try it yourself and see how your application behaves if you notice any performance degradation, so you should be good to keep the new numbering.

    You keep a copy of your old folder from catalog PSE10 somewhere? It is often possible to get a usable conversion by creating a new folder from catalog containing only the database file 'catalog.pse10db '.

  • using apex for a list of the number of 'To' article

    Greetings,

    I have a calculation that looks like this:

    --------------------------------------------------------------

    Select count (mr.mr_id)

    of ds_moriver Sir

    where mr.approved = 0 OR mr.approved IS NULL

    .....

    and mr.mr_id NOT IN (: P62_MRID)

    ----------------------------------------------------------------------------------

    I'm looking to enter numbers in the NOT IN clause as ' 123, 234... »

    I have an element of (P62_MRID) text field where the user can enter the credentials for the NOT IN clause.  Thus, for example, 13 578 182.  If the user enters a number, it works fine.  If the user enters 2 numbers with a comma (13 578 182) then I get this error when the calculation is performed:

    ORA-01722: invalid number

    Until it is replaced by 13 578 182 for P62_MRID the SQL statement must calculate as:

    Select count (mr.mr_id)

    of ds_moriver Sir

    where mr.approved = 0 OR mr.approved IS NULL

    and mr.mr_id NOT IN (13 578 182)

    "Why I get the error ' ORA-01722: invalid number '?

    Thanks in advance!

    You're certainly not the first person who has ever wished they could do! This is a mistake because the IN operator does not evaluate the content of variables. You couldn't do this kind of thing in pure PL/SQL using a variable declared either. In APEX, you can sometimes use substitution syntax point around that sort of thing. Yes, instead of use (: P62_MRID), try (& P62_MRID). Note that I did not really this and APEX is sometimes uneven on where it supports the substitutions of point, but it's an easy thing for you to try. Good luck!

  • Display a personal message for a report when the number of records returned.

    Our application has a page that displays the results of several SQL statements which are defined as reports. A report should in particular only to display a custom message when the County of invoices with status individual > 0 and not the exact time charged count himself. I got the layout to not display the meter, but I have to be able to display a personalized message that says ' problem invoices exist.» See report of bills, for more information please". I looked on the report attributes definition page but I can't find how to show this custom message. Any tips?

    Simply create a text on the page element. Make read only and put your message in the default value.
    Now put a condition on this point, to display only when required.

    Do a web search on each must you will know more about what it is. There is usually a lot of processes running, and it's not a problem.

    I do * not * recommend to stop the processes from running. You are more likely to cause a problem serious that solve a.

    Regarding why your computer is slow, it is highly unlikely that this is because there are too many process running. There are several possible reasons, but perhaps the most likely is that you are infected with malware. What anti-virus and anti-spyware programs do you run?

  • Dynamically adjust the size of table control panel

    Hello

    I have a combo box control that I drag within a table.

    Since my request depends on the size of the initialized array, I'm having a problem with the car, adjust the number of items to display on the control panel.

    Say for example, I wanted to have 4 zones of drop-down list on my table, I drag the table to show the 4 combo boxes.

    The problem is that if I wanted to change this moment of execution at 2 or 6 elements, it still shows 4 items in the control.

    Is there a way to adjust based on the number of items?

    I found it... must be a day tired... Since the solution is too simple

  • License AnyConnect SSL - increase in the number of users

    I have an ASA 5510 with SSL 100 users license. I'll add additional VPN users - how can I go on the increase in the number of authorized users? Can I buy a license 50 users and they will combine (to 150 users)? Or I have to jump up to 250 users?

    I contacted Cisco and got two different answers (see above). If anyone has a part number, it would be great.

    Thank you

    Hi Greg -.

    The next bump in licensing for Anyconnect Essentials is the number of users of 250 max (L-ASA-AC-E-5510 =). If you run Anyconnect Premium is more gradual. Here are the part numbers and user account for Premium evasion.

  • samples per channel and the number of samples per channel

    in my DAQ mode samples finished program, there are two screws: timing and read.vi DAQmx DAQmx.

    I have to set the parameter to "samples per channel" DAQmx timing.vi and 'number of samples per channel' on DAQmx read.vi... Is there a relationship between these two?

    My laser runs at 1 K Hz. I want to go to the wavelength, wait for a number of shooting lasers, read the data and move on to the next page...

    Thank you

    Lei

    In your case, the VI will acquire the lesser of either:

    The "samples per channel" that you have defined on the timing DAQmx VI

    -OR-

    The number of iterations of your for loop (N) times the 'number of samples per channel"that you have defined on the DAQmx read VI

    The "samples per Channel" VI DAQmx of timing for a finite acquisition dictates how many samples the DAQ hardware should acquire in it's onboard buffer before indicating that the acquisition is complete.  "The number of samples per Channel" on the read DAQmx VI dictates how many samples the DAQmx driver must return buffer on board the aircraft to your application.

    Let's say the "samples per channel" on the calendar DAQmx VI is set to 50.  Thus, the card will acquire 50 samples and place them in the edge of the buffer, then stops.  Suppose we have the 'number of samples per Channel"on the DAQmx reading VI the value 3 and what we call the VI in a loop For which runs 10 times.  Thus, every time the DAQmx lu VI is called, it will wait until there are at least 3 samples in the buffer, and then return these three.  We call the VI a total of 10 times, then we will answer 30 total samples.  Thus, the last 20 samples acquired the card remains in the buffer and are destroyed when the task is disabled.

    Now let's say that we increase the "number of samples per Channel" on our DAQmx Read VI at 10.  VI Read will wait until 10 or more samples are in the buffer, and then return these 10. Thus, we will be back all 50 samples map acquired by the 5th iteration of the loop For.  The 6th time we call him VI DAQmx Read it expires, because there will never be another 10 samples in the buffer, and the VI returns a warning.

    This clarifies things?

    The purpose of this behavior is to allow you to both set the total number of samples that the DAQ hardware will acquire and also control how much of these samples is returned whenever you call the DAQmx Read VI.

    Kind regards
