Database Considerations (ODBC)
Technical
On 64-bit operating systems, the ODBCData Sources created by the Data Source
(ODBC)icon in the Administrative Tools will not appear here, as PReS Suite is 32-bit
and cannot access the 64-bit data sources. In order to create an ODBCconnection visible
by PReS, you will need to access the 32-bit version of the ODBCmanager, available in
C:\Windows\SysWOW64\odbcad32.exe .
The following considerations should be kept in mind while working with ODBCDatabases in
PReS Suite.
l All databases
l
User Rights:During normal operation, Read/Write to tables should be sufficient.
However, during the initial setup, the Create/Drop tables rights is necessary.
l Minimum 100MBof database size is required as a minimum, but the space
requirement depends on the implementation. The more active documents in the
database, the more space is used - note that this progression is rather linear.
l Regular database maintenance is required, such as database compacting, is
required by a system administrator.
l It is recommended to create an ITprocess that backs up the database regularly.
l The recommended ideal setup is a dedicated SQLServer PC, accessed by PReS
Workflow through an ODBCconnection on the local network.
l Microsoft Access
l Database file (mdb)must be local to the PReS Workflow computer. It cannot be
located on a network drive or another server.
l Total database size is limited to 4GBof data.
l Total size of a single table is 2GB.
l May be unstable in large implementations.
l MySQL
l Database can be in any location, but performance will depend on the speed of the
connection between PReS and the MySQLserver.
