Linux

Pervasive PSQL v9 improves Linux support in the following ways:

Performance Equality with Windows

This release increases the relational engine performance on Linux by adapting a common-address space technology used previously only on Windows.

Now the Linux engine should have performance similar to the performance on Windows, assuming similar hardware.

Client Use of idshosts File and PIDS Protocol Strings

Typically, an application provides its own file location information. As an alternative, you may provide file location mapping based on information in the text file idshosts. If you choose, a Linux client requester can use idshosts when communicating with a Pervasive PSQL server on Windows, Linux, or NetWare.

You must add the idshosts file to the $PVSW_ROOT/etc directory (by default, /usr/local/psql/etc). Idshosts may include uniform naming convention (UNC) file locations. Linux requires the use of forward slashes in UNC paths.

Legacy applications that used IDS could also pass file location information through the use of a PIDS protocol string. The Linux client requester automatically converts PIDS strings to the URI format. See Conversion of PIDS Strings .
