This ドキュメント covers the following topics:
This section describes the new features, enhancements and corrections that apply to the Version 1.5.2 of the Entire Transaction Propagator (ETP).
Error Corrections:
ETP Version 1.5.2 contains all Zaps and INPL updates
applied to ETP Version 1.5.1 as error corrections.
Database IDs:
ETP now supports DBIDs in the range of 1 to 65535. However, the value
of 255 remains excluded.
File Numbers:
ETP now supports file numbers in the range of 1 to 65535.
Master Files and Log Files:
The maximum number of master files per database has been increased to
512. Also, the maximum number of log files per database IDs has been increased
to 512.
Replicate Files:
For a specific log file, transactions may be replicated to up to
65535 databases. A specific replicate database may have a maximum of 512
replicate files defined for which transactions are replicated from that log
file. Other log files may also have up to 512 replicate files belonging to that
database.
Conversion of Existing Administration Files:
Existing administration files will be converted automatically when
the MENU program is started.
New Product Documentation Medium:
The following changes and enhancements apply to the ETP product
documentation:
The ETP product documention is supplied online on CD-ROM as it is common practice for all Natural products.
Hardcopies of the documentation can be printed out from the PDF files that come with the documentation.
For information about online documention usage, see Documentation-Related Frequently Asked Questions (FAQ) on the Natural CD-ROM overview page.
Entire Transaction Propagator Version 1.5.2 requires that Natural Version 4.2. is installed.
The prerequisite operating/teleprocessing systems and required versions of other Software AG products are to be found in the current Natural Release Notes.
It is essential that the ETPNUC module and the ETP Natural
programs in library SYSETP have the same version. Using a Version
1.5.2 ETPNUC module with ETP Version 1.4.1 Natural programs - or
vice versa - can cause unpredictable results.
The Natural parameter ETPSIZE is still
accepted by Natural, but it is no longer necessary to specify this parameter.
The required storage (approx. 10 KB) will be automatically allocated when the
first call to an ETP database is issued. Any value specified for the
ETPSIZE parameter will be ignored. The size of the
ETPSIZE parameter should be left at its default
(ETPSIZE=0).
As the Natural DATSIZE parameter
is automatically adjusted to the required length, it is no longer necessary to
adjust the value of the Natural DATSIZE parameter for a
Natural environment running a replication task. However, the
DATSIZE in such an environment will be approximately 170
KB.
After ETP Version 1.5.2 is installed and when the
MENUcommand is invoked for the first time in the ETP
maintenance utility, the ETP administration file is automatically migrated to
the ETP Version 1.5.2 format and an appropriate message is displayed.
Afterwards, any attempt to access the migrated administration file from an earlier version of the ETP maintenance utility is denied.
Before enabling the new ETP maintenance utility, all log files must be
empty and all log and confirmation files must be accessible for the migration
process. Migration of the administration file from ETP Version 1.4 format to
ETP Version 1.5 format is performed automatically when the ETP Version 1.5
maintenance utility is invoked for the first time. If a previous ETP version is
installed, you should use the Natural utility SYSMAIN to delete
the contents of library SYSETP before installing ETP Version
1.5.2. Following installation of ETP Version 1.5.2, the maintenance utility of
any earlier ETP version will be denied access to the administration file.
Otherwise, ETP Version 1.5.2 is compatible with ETP Version 1.4.1 The FDT of the administration, log and confirmation files remains unchanged.
