OpenTP1 Version 7 Operation
In multiOpenTP1 configuration, a shared library area resides on the memory of each OpenTP1. When the versions of two OpenTP1 systems are the same, one shared library can be shared by them (only for HP-UX). Since two OpenTP1 systems reference one shared library, memory consumption can be reduced.
To share a shared library by multiple OpenTP1 systems, match all the SHLIB_PATH environment variables of the OpenTP1 systems. The following shows the procedure.
d1:2:respawn:env SHLIB_PATH=/BeTRAN/lib /BeTRAN/lib /servers/prcd /BeTRAN d2:2:respawn:env SHLIB_PATH=/BeTRAN1/lib /BeTRAN1/lib /servers/prcd /BeTRAN1 |
d1:2:respawn:env SHLIB_PATH=/BeTRAN/lib /BeTRAN/lib /servers/prcd /BeTRAN d2:2:respawn:env SHLIB_PATH=/BeTRAN1/lib /BeTRAN1/lib /servers/prcd /BeTRAN1 |
Change the environment variables that set the command issuance environment.
Environment variable | OpenTP1 A | OpenTP1 B |
---|---|---|
DCDIR | /BeTRAN | /BeTRAN1 |
DCCONFPATH | /BeTRAN/conf | /BeTRAN1/conf |
SHLIB_PATH | /BeTRAN/lib | /BeTRAN1/lib |
Environment variable | OpenTP1 A | OpenTP1 B |
---|---|---|
DCDIR | /BeTRAN | /BeTRAN1 |
DCCONFPATH | /BeTRAN/conf | /BeTRAN1/conf |
SHLIB_PATH | /BeTRAN/lib | /BeTRAN/lib |
If the versions of the OpenTP1 systems are different, the operation cannot be assured. If the directory specified by SHLIB_PATH does not contain a library, the OS suppresses activation of the process.
If SHLIB_PATH is defined in the putenv format in the system definition, define it as in paragraph (2).
