OLP System Task

The OLP task invokes online PLOG that allows you to view the current contents of the system log online. You can use OLP only when the log is assigned to the DDLDCLOG area of the data dictionary.

The OLP task invokes online PLOG that allows you to view the current contents of the system log online. You can use OLP only when the log is assigned to the DDLDCLOG area of the data dictionary.
To guarantee that the most recent data is shown, OLP forces the current DDLDCLOG buffer to be written at initial task code invocation and each time the TO or FROM parameters change.
This article describes the following information:

Syntax
You begin an online PLOG session by using the following OLP task code syntax:

      The current column value is displayed in the OLP screen's COL field. For example, the following partial display shows you what you would see if you specified a column of 10:
         FROM       ON        TO       ON      COL PRT SKIP   LOG TYPES  ROLL STATUS  17:47:50 2003-08-26 18:17:50 2003-08-26

       (WT/TR/DU/  ) 040
      If
      skip-amount
      is greater than 9999, the SKIP field on the OLP screen displays only the 4 right-most digits of the skip amount. For example, if you specify 12345, you would see:
        FROM       ON        TO       ON      COL PRT SKIP   LOG TYPES  ROLL STATUS 17:47:50 2003-08-26 18:17:50 2003-08-26 010 OFF

    n
    applies only when you are already using OLP.
  • PF
    n
    Simulates 3270-type PF (programmer function) keys at terminals that don't have these keys.
    N
    specifies an integer value in the range 1 through 12. PF
    n
    applies only when you are already using OLP.
    For a list of valid control keys, see "Usage".
    • cursor-position
      Specifies a line number identifying the cursor location required for the operation associated with the PF key.
  • PLimit
    Specifies the maximum number of lines OLP is allowed to queue for printing at one time. Print queueing is enabled by the PRINT option described below.
    When this limit is exceeded, OLP displays the XSPRT error-status message in the screen's STATUS field.

      Range:
      1 - 32,767
      Default:
      1000

    ON
    in the screen's PRT field, as shown on the following partial screen:

    are not
    queued to a printer.
    This is the default.

    • record-count
      Range:
      1 - 32,767
      Default:
      10,000
      Note:
      0 (zero) disables the Rlimit checking so that OLP continues to read from the log until the display is filled, or until the end of the log is reached.
  • ROll
    Specifies the number of columns to skip when scrolling left or right. The current roll value is displayed in the OLP screen's ROLL field.
    • roll-amount
      Range:
      0 - 131

      40
  • SCRoll
    Displays long log record on one line. This is the default.
    To scroll:
    • Press PF11 to view the right-most portion of a long log record. OLP pages right by the number of columns specified by ROLL option (see above).
    • Press PF10 to page back to the left side of the OLP display.
  • WRap
    Wraps long log records around to a second line. Pressing PF11 and PF10 does not change the online PLOG display.
  • SIze
    In full screen mode, specifies the full message area of the screen.
    • page-size
      Specifies the number of lines in the screen's message area.
      Page-size
      is an integer in the range from 2 through the number of lines in the screen's message area.
      The message area begins
      after
      the top three lines on the screen. OLP reserves these three lines of the screen to communicate with you. Thus, if your screen can display a total of 24 lines,
      page-size
      can be an integer in the range from 2 through 21.
  • TRace
    Requests display of user trace information. TRACE is the default.
    When you
    have
    requested display of user trace information, OLP displays
    TR
    in the LOG TYPES field, as shown on the following partial screen:
      FROM       ON        TO       ON      COL PRT SKIP   LOG TYPES  ROLL STATUS 17:47:50 2003-08-26 18:17:50 2003-08-26 001 OFF 0000 (WT/

Usage
OLP display modes
You can use OLP in either of the following display modes:
  • In
    full screen mode
    , OLP displays one full screen of log records at a time. This discussion assumes that you are using OLP in full screen display mode.
  • In
    line mode
    , OLP displays one log message at a time. This display mode is appropriate at terminals that don't support full screen display, such as certain TTY terminals. You request to use line mode by invoking OLP with the
    NOFSCR
    session option.
Status messages
The following table lists the status messages that OLP returns in the screen's STATUS field:
Message
Meaning
FIRST
OLP has reached the beginning of the requested time period.
LAST
OLP has reached the end of the requested time period.
WRAP
OLP has wrapped the log file around to the beginning of the DDLDCLOG area.
XSREC
OLP read more records from the DDLDCLOG area without selecting a line for the display than the RLIMIT session option allows.
XSPRT
OLP queued more lines for printing than allowed by the PLIMIT session option.
TIME
You entered an invalid time (for example, 24:06).
DATE
You entered an invalid date (for example, 83367).
TIMES
The beginning of the requested time period is later than the end of the requested time period.
SYNTX
You entered a session option incorrectly.
PAPFK
You pressed an unsupported PA or PF key.
LOGIC
A logic error has occurred.
S
nnnn
The displayed four-digit error-status code (indicated here by
nnnn
was returned to the ERROR-STATUS field of the IDMS communications block.
LOCAL
The time is displayed in the local format.
UTC
The time is displayed in the UTC format.
Specifying session options
You can specify OLP session options at both of the following times:
  • When you invoke OLP
    . For example, you specify the PRINT and WRAP session options when invoking OLP as shown below:
V105 ENTER NEXT TASK CODE:      CA IDMS release nn.n tape volser node nodename  olp print wrap     <<  Type session options on the same                         line as the OLP task code
  • When you are using OLP
    . To do this, you type options you want in the third line of the OLP screen. Additionally, you can update the FROM and TO times by typing new times and dates directly over the previous ones.
OLP control keys
The following table summarizes the actions associated with OLP control keys:
Control Key
Purpose
Clear
Terminates the OLP session
Enter
If the command line has no input, Enter simulates the PF8 key; otherwise, it processes the command.
PF1/PF13
Scrolls forward to the line above which the cursor is positioned
PF2/PF14
Sets the page size to the line above which the cursor is positioned
PF3/PF15
Switches between the SCROLL and WRAP display formats
PF5/PF17
Searches backward for the previous occurrence of the search string
PF6/PF18
Searches forward for the next occurrence of the search string
PF7/PF19
Scrolls backward the number of lines indicated by the SKIP parameter
PF8/PF20
Scrolls forward the number of lines indicated by the SKIP parameter
PF9/PF21
Terminates the OLP session
PF10/PF22
Scrolls left the number of columns indicated by the ROLL parameter
PF11/PF23
Scrolls right the number of columns indicated by the ROLL parameter
Sample OLP Session
 
Assume that you need to find out which logical terminal varied area CUSTOMER-REGION offline sometime after 2:00 pm. you initiate the online PLOG session by entering the task code (for example, OLP), as shown below:
V105 ENTER NEXT TASK CODE:      CA IDMS release nn.n tape volser node nodename  olp from 14:00 nodump
In this example, you specify
nodump
to suppress display of snap dumps.
You now search for CUSTOMER-REGION by using the FIND session option:
FIND 'CUSTOMER-REGION'
You then request display of logical terminal IDs:
LTERMS
You could have conducted the above steps in others ways. For example, you could have given the search string and specified display of logical terminal IDs when you invoke OLP at the beginning of the session.
You
terminate the session
at any time by entering BYE in the third line of the OLP screen.
