How to define a summary database for use in a TABEX/4 browser application?

Procedure
  • In the Alloc script in the Unix directory "etc" the partial databases of the summary DB must be defined with the following instructions :

ALLOC FI(ddname) ...

  • In the Sysparm of the web application, which is defined in the file boiadmin.properties in the WEB-INF directory of the TABEX application, the DD-name of a file is specified which contains the summary specifications.
    Assumption
    : the file with the summary specifications shall be called DDDEFS.
  • extension of Sysparm by the entry "CTDD":

existing-sysparm-specifications,CTDD=+DDDEFS

  • File (DDDEFS) must also be allocated in the Alloc-Script: The file must be a text file with a fixed record length of 80.

>ALLOC FI(DDDEFS) ...

 

Example:

Name Summary-DB ... MYSUM

Name 1st part DB ... MYPARTA

Name 2nd part DB ... MYPARTB

The entry in this file DDDEFS must have the following structure:

for a summary DB:

ddsummary:dsn>dd1-dd2(-dd3-..ddn)

e.g.:

MYSUM:MYSUM-VIRTDSN>MYPARTA-MYPARTB

for a chain summary DB:

ddsummary:dsn>>dd1-dd2(-dd3-..ddn)

e.g.:

MYSUM:MYSUM-VIRTDSN>>MYPARTA-MYPARTB

To define a single summary DB, the file DDDEFS has exactly one row, as described above.
