z/TPF Program Management - IBM

Load E-type programs and files to an enabled system
Complete the following steps to load new E-type programs and files to a z/TPF
system:
1. “Create an E-type loader input file.”
2. “Load E-type programs and files to a storage medium”
3. “Load, activate, and accept a loadset of programs and files” on page 82.
E-type loader functions affect only the program base that is being used on the
processor that the function was requested from. If other processors are using a
different program base, those processors do not see the effects of E-type loader
functions until they begin to use the same program base.
For example, in a loosely coupled environment where processor A is using program
base 1 and processor B is using program base 2, if you issue the ZOLDR
ACTIVATE command on processor A, the specified loadset is started on all
processors using program base 1. Because processor B is using program base 2,
the specified loadset is not actually activated on that processor until you perform an
initial program load (IPL) using program base 1.
When using the E-type loader to load files, you must use the ZOLDR ACCEPT
command to ensure that the file changes are persistent. In the case of an affiliated
file, changes to the file in the loadset are not reflected in the existing online version.
If you use the E-type loader to move a C function from one program to another, all
callers of the function must be included in the same loadset.
If you use the E-type loader to move an entry point from one program to another,
the loadset must be deactivated or accepted before the entry point can be moved
again.
Create an E-type loader input file
You can create an E-type loader input file on z/OS or Linux.
To create an E-type loader input file based on a control file, enter bldtpf -old. The
bldtpf command, by default, will write the loader input file to bldtpf.old_loaddeck.
Enter man bldtpf for more information.
To manually create an E-type loader input file, create a file containing the E-type
loader input parameters. See “E-type loader” on page 115 for more information.
See “OLDR input file” on page 158 for an example of an E-type loader input file.
Load E-type programs and files to a storage medium
To load an E-type loader input file on z/OS, use the E-type loader JCL cards.
Sample JCL is provided in the base/samples/jcl directory. See “JCL statements” on
page 117 for more information.
You can use the loadtpf command on Linux to load E-type programs and files to
your z/TPF system. You can specify a control file, a loader input file, a load file, a
program name, a file, or a shared object as input and loadtpf will call the bldtpf and
