=_ESCORT_SYSDB
This DEFINE is used for testing NonStop AutoTMF software. It permits the user to
establish an independent NonStop AutoTMF environment on the same system. In
general, its use is not required and is not recommended in a production environment.
In order to test a new version on NonStop AutoTMF software in parallel with an existing
version, you should use an alternate monitor and MapDB instead.
The =_ESCORT_SYSDB DEFINE is class CATALOG and specifies a subvolume for
the SysDB tables. If this DEFINE is present when the CI is started, the CI will not look
for the normal SysDB, but will use the one specified. Thus, the CI will operate only with
MapDBs and monitor processes that were created under the specified SysDB.
=_ESCORT_SYSDB DEFINE has no effect on an application, since the DEFINE
obtains all configuration information from a monitor process. To run an application in
the separate environment, the =_ESCORT_MONITOR DEFINE selects a monitor
process defined in that environment.
A typical =_ESCORT_SYSDB DEFINE is added with the following TACL command:
=_ESCORT_MONITOR
This DEFINE selects a monitor process for the CI session; using this DEFINE is
equivalent to specifying the monitor name on the command line or issuing an OPEN on
the monitor name.
The DEFINE is added with the following TACL command:
Alternate MapDBs are typically created to test a new version of NonStop AutoTMF
software. By issuing the INFO MAPDB * or STATUS MONITOR * commands in the CI,
you can determine the currently defined monitor process names. A monitor process
name must contain exactly 5 characters, including the $. The default monitor process
name is $ZESC.
