ViewPoint Pathway Configuration Files
ViewPoint uses these three files to configure and start its Pathway system:
INSTVHS generates two Pathway configuration files in the VHS-BROWSER-SUBVOL:
The ViewPoint PATHCONF file is updated by INSTVHS to invoke VHSDEFS and
VHSSTRT. You can specify the name of the ViewPoint PATHCONF file during
installation by modifying Parameter 4, PATHWAY-PATHCONF-FILENAME.
INSTVHS updates the ViewPoint PATHCONF file by adding these two command lines:
OBEY $SYS1.VPTTOOLS.VHSDEFS
OBEY $SYS1.VPTTOOLS.VHSSTRT
The VHS Browser facility is added and started automatically whenever you start your
ViewPoint Pathway system cold.
Too Many Servers
When adding VHS servers into your ViewPoint Pathway environment, if you reach the
maximum number of server processes and/or server classes allowed, one of these
events is generated:
ZPWY-ERR-PM-TOOMANYSC (1102)
ZPWY-ERR-PM-TOOMANYSCPROCESS (1103)
To resolve this problem, increase the Pathway MAXSERVERCLASSES and
MAXSERVERPROCESSES parameters in the PATHCONF file. For example, supply
these commands:
SET PATHWAY MAXSERVERCLASSES 20
SET PATHWAY MAXSERVERPROCESSES 100
Then load the ViewPoint application.
PATHDEFS Adds the ViewPoint servers to the Pathway configuration.
PATHSTRT Starts the ViewPoint servers.
PATHCONF Adds the ViewPoint TCP and program to the Pathway configuration
and starts your Pathway system cold. PATHCONF invokes
PATHDEFS and PATHSTRT to perform the cold start.
VHSDEFS Adds VHS servers to the Pathway configuration.
VHSSTRT Starts the VHS servers.
