SOS TurboIMAGE Process Detail
The TurboIMAGE Process Detail screen (Figure 21.1) contains global information – regarding all databases and datasets accessed by the process and detailed information – regarding access of the process for a specific dataset and database.


Figure 21.1 SOS TurboIMAGE Process Detail screen
This screen is available through the shortcut key from any of the “SOS – TurboIMAGE” screens and through the screen selection menu to the rest of SOS screens.
To access the TurboIMAGE Process Detail screen from any SOS display screen:
  • Type S from the SOS Enter command: prompt to view the Screen Selection Menu screen or type J.
  • From the Screen Selection Menu screen or at Enter Screen Code: prompt, enter N (Turbo Image Process Detail Screen).
  • At the secondary prompt, enter the PIN for the process that you need to see data for. The TurboIMAGE Process Detail screen will display. An example of the screen is shown in Figure 21.1.

    TurboIMAGE Process Detail Screen Display Items

    TurboIMAGE Process Detail

    The TurboIMAGE Process Detail portion of the screen contains data currently available in the current Process detail screen (like PIN, SESS, PRI, TYPE, PROG, and USER).
    The one TurboIMAGE item displayed here is Int OK%, which is the number of successfully performed intrinsic calls issued by the process. A successful call is defined in this context as an intrinsic call that returned 0 in the status parameter of the call. The item is percentage of all intrinsic calls issued by the process on any database or dataset.

    Key Stats for Process

    The Key Stats for Process portion of the screen displays the data items listed in the next table.
    Table 21.2 SOS Key Stats for Process data items
    Data Item
    Description
    CPU%
    The percentage of utilized CPU time during the current interval used by the process for DBI calls.
    CPU/I
    The average CPU time used per DBI call in the current interval, measured in milliseconds.
    I/s
    The average number of DBI calls per second performed by the process in the current interval.
    Ela/I
    The average completion time per DBI call performed by the process in the current interval.

    Process Activity by Intrinsic

    The Process Activity by Intrinsic portion of the screen displays the following information.
    Table 21.3 SOS Process Activity by Intrinsic data items
    Data Item
    Item for which Data is Displayed
    Get
    DBGET intrinsic calls
    Put
    DBPUT intrinsic calls
    Update
    DBUPDATE intrinsic calls
    Delete
    DBDELETE intrinsic calls
    Lock
    DBLOCK intrinsic calls
    Unlock
    DBUNLOCK intrinsic calls
    Open
    DBOPEN intrinsic calls
    Close
    DBCLOSE intrinsic calls
    Begin
    DBBEGIN intrinsic calls
    End
    DBEND intrinsic calls
    XBegin
    DBXBEGIN intrinsic calls
    XEnd
    DBXEND intrinsic calls
    Find
    DBFIND intrinsic calls
    Info
    DBINFO intrinsic calls
    Ctrl
    DBCONTROL intrinsic calls
    Rollback
    DBXUNDO intrinsic calls
    The counters and times for each of these data items are:
  • CPU/I - The average CPU time during the current interval used per DBI call performed by the current processes on all databases (measured in milliseconds).
  • Ela/I - The average completion time per DBI call performed by the current process on all databases during the current interval.
  • Int/s - The average number of calls per second, calculated for DBI calls performed by the current process on all database—a separate count for each item.
  • Process Activity by Database and Dataset

    The Process Activity by Database and Dataset section contains performance data for databases and datasets accessed by the process. It is similar to the “Process Information” list in the Global Summary screen.
    The look of the section depends of the amount of collected TurboIMAGE data. Dataset performance data is collected at user’s request and it is an option (17) in the SOS Option Screen. This measure was taken as a result of increased resource usage that occurs when collecting all TurboIMAGE data. You are able to collect dataset performance data if necessary and you are able to prevent it from being collected if such data presents no interest for you and its collection is an unnecessary overload for the system. You must have SM or OP capabilities in order to change TurboIMAGE options in the SOS Main Options menu.
    Depending on whether not dataset performance data is being collected, there are two ways to display this section.
    The common features to both frame types are:
  • The databases are indexed by their names, making them easy to find. The TIDBID is not placed to the left of the database name because it is used to refer the database and not as an index item. Within every database display block the datasets are indexed by their name.
  • The database data is computed for the last collection time interval, presenting current data.
  • For each database there is a database display block that is made of lines containing data about the database and its datasets. The performance data displayed on each line is computed for the entire database or one of its datasets. The data displayed on the first line is per entire database and the following lines (contained by this database display block) contain data for each one of the database’s logged datasets. The items displayed are described in the next table.
    Table 21.4 Process Activity by Database and Dataset data items
    Data Item
    Description
    Database
    The database name.
    ID
    The database ID is the number uniquely assigned by SOS to the database. The user will have the option to use this ID instead of the database name in order to get to the database’s detail screen.
    CPU%
    The percentage of utilized CPU time during the current interval used for DBI calls performed by this process on the database.
    Int/s
    The average number of calls per second, calculated for DBI calls performed by this process on the database—a separate count for each item.
    Put/s
    The average number of DBPUT intrinsic calls per second.
    Del/s
    The average number of DBDELETE intrinsic calls per second.
    Lock/s
    The average number of DBLOCK intrinsic calls per second.
    Get/s
    The average number of DBGET intrinsic calls per second.
    Upd/s
    The average number of DBUPDATE intrinsic calls per second.
    Oth/s
    The average number of other DBI calls.
    The differences between the two section types/looks:
  • Dataset information is not being collected
  • The data presented on the dataset display lines contains counts and percentages computed per the entire time interval since collection was started – accumulated data.
  • The header of the frames is displayed on two different lines (for databases and datasets, because of the way that accumulated data is presented in SOS – that is enclosed in brackets.
  • The database lines are underlined.
  • Dataset information is being collected:
  • The data presented on the dataset display lines contains counts and percentages computed per the last collection time interval – just like database performance data.
