Define Configuration Options

You can use two methods to pass configuration information to the OPSLOG WebView server when the server is initiated:

• JCL EXEC PARM=value field

  This method has a 100-character limit imposed by z/OS, which could be inadequate to support all the required parameters.

• SYSIN ddname statement, which is in the OPSLOGSV started task

  This method is optional and it can do the following:

  • Accommodate an unlimited number of characters
  • Be used in addition to the PARM=value field, or in place of it
  • Name a PDS member or flat file containing fixed or variable length records

Every parameter that can be assigned in PARM can also be assigned using the SYSIN DD file. Any parameter defined in both places will be set from the SYSIN file. One difference between the two methods: The PARM field has all options in a single concatenated character string, whereas each parameter must be stored in a separate record in the SYSIN file. SYSIN must be a DASD-resident file.

There are three types of SYSIN records, which are distinguished by the character in column 1.

• - (minus sign) or / (slash, virgule, diagonal, or solidus)

  Indicates a parameter line. Both the / and - perform exactly the same function; they mark the lines to be parsed for parameter settings.

• * (asterisk)

  Signifies a comment line. Use asterisk comment lines to keep detail information about settings, or any other general information. Asterisk comments are not sent to the SYSPRINT file.

• ; (semicolon)

  Signifies a comment line that will be printed in the SYSPRINT data stream.

The following is a sample procedure:

//OPSWEBVW EXEC PGM=OPSLOGSV,TIME=NOLIMIT,REGION=0M
//SYSPRINT DD SYSOUT=*           <=== For server console messages
//STDOUT   DD SYSOUT=*           <=== For error/debug messages
//STDERR   DD SYSOUT=*           <=== For error/debug messages
//CEEDUMP  DD SYSOUT=*           <=== For z/OS LE reports
//SYSUDUMP DD SYSOUT=*           <=== Dump dataset
//SYSIN    DD DISP=SHR,DSN=MY.PDS(SYSIN)

Note: The following statement is not acceptable because the JES Spool system is not available to a started task:

//SYSIN    DD *
