TIP
Glossary
The OS 2200 environment in which transaction processing applications are created and
maintained. The TIP system is integrated with the Exec.
TIP common data bank file (TCDBF)
An FCSS file that the administrator can set up to hold tables of static data. When the file
is registered as a TCDBF, a copy of it is moved into main storage as a common bank, and
any application program can reference it.
TIP file
A file reserved for TIP within a TIP/Exec file using the TFUR or FREIPS utility. Users can
create a TIP file as a permanent, temporary, or scratch file. A permanent file can be a
simplex or duplex file. At creation time, the user must define a TIP file as a TIP (FCSS)
file, UDS/TIP file, or Freespace file.
• UDS/TIP file: A permanent TIP user file that users access and maintain through UDS.
The FREIPS utility is used to set up TIP user files as UDS/TIP files, with DMS 2200
area numbers. The DMS 2200 areas are numbered downward from the upper end of
the range of TIP file numbers.
• duplex TIP file: A permanent TIP file with two identical legs (copies) that reside in
two separate TIP/Exec files on separate (but identical) devices. At creation time, you
define a file as either a simplex file or a duplex file. Updates to one leg of the file are
automatically made to both legs of the duplex file.
• Freespace file: A TIP user file in which the user application programs have record
space allocated and released as needed by Freespace functions when calling FCSS.
• permanent TIP file: A TIP file set up inside an Exec file for the application database.
This type of file is assigned permanently to TIP, so any transaction program accesses
it quickly, without having to assign it or release it. A permanent TIP file may be a TIP
(FCSS) file, UDS/TIP file, or Freespace file. In the XTC environment, permanent TIP
files can be defined by the site administrator in either the local or the shared TIP
FCSS directory.
• temporary TIP file: A fixed-length TIP (FCSS) file that can be assigned by a
transaction or batch-connect program by means of the FCSS AS function. It remains
in the system until specifically released. Shared TIP files cannot be used for
temporary files.
• scratch TIP file: A fixed-length TIP (FCSS) file that can be assigned by a transaction or
batch-connect program by means of the FCSS AS function. This type of file exists
only for the duration of the execution or connect period, and is released
automatically by TIP. It may be released by a TIP file control call before termination
of the execution or connect period. Shared TIP files cannot be used for scratch files.
• simplex TIP file: A permanent TIP file that exists as a single copy in a TIP/Exec file.
• TIP (FCSS) file: A TIP user file with a fixed record structure that is accessed and
maintained through TIP file control. The TFUR or FREIPS utility is used to set up a
TIP (FCSS) file.
TIP file control
An Exec component that handles the creation and maintenance of FCSS and Freespace
files and access to the files. It is also called TIP file control superstructure (FCSS).
