Name is a string. a, b, c, d, e, and f are as described below.
The [Databases] section of the configuration parameter (CPF) file contains an entry for every database connected to the instance. Each entry has up to six comma-separated arguments that define a database. The only argument that is required is the first, the directory specification. If the other arguments are not specified, then the default is used. The values are:
a — Full directory specification for database file. Required.
b — Remote instance name (empty for local instance). If the instance is remote (nonempty name), subsequent fields are ignored. Default is the local instance.
c — Must mount at startup (1 or 0). When enabled, the database must be mounted at startup, or startup fails. Default is 0 (database is not mounted at startup).
d — This value is ignored and may be left blank.
e — This value is ignored and may be left blank.
f — Stream Location. Directory where the streams associated with this database go. The default is blank — "" (which InterSystems recommends.) This default location is in the subdirectory stream, underneath the database directory. For example, for a database located in c:\abc, the default stream location is c:\abc\stream.
By default, even if they are not specified, the IRISSYS, IRISLIB, IRISTEMP, and IRISAUDIT databases must be local to the instance and mounted at startup.
In the [Databases] section, each line is a database with arguments Name=a,b,c,d,e,f. Here is an example from Windows:
[Databases] IRISSYS=c:\InterSystems\IRIS\mgr\ IRISLIB=c:\InterSystems\IRIS\mgr\irislib\ IRISTEMP=c:\InterSystems\IRIS\mgr\iristemp\ IRISAUDIT=c:\InterSystems\IRIS\mgr\irisaudit\ USER=c:\InterSystems\IRIS\mgr\user\ SALES=c:\sales\,SALESERVER ; Database is on instance SALESERVER BILLING=/usr/billing/,,1 ; Database is local and mount required
Example of remote databases without mirroring:
PRDAUDIT=c:\InterSystems\IRIS\mgr\prdaudit\,PRD PRDDCIFC=\InterSystems\IRIS\mgr\prddata\,PRD PRDERR=\InterSystems\IRIS\mgr\prderr\,,1
Example of remote databases with mirroring. Note in this mirrored example the two remote databases, both mirrored and nonmirrored, are formatted differently than they would be in a nonmirrored environment.
PRDAUDIT=:mirror:PRDMIRROR:PRDAUDIT,PRD - Mirrored remote database PRDDCIFC=:ds:PRDDCIFC,PRD - Nonmirrored remote database PRDERR=\InterSystems\IRIS\mgr\prderr\,,1 - Local database
Changing This Parameter
On the Local Databases page of the Management Portal (System Administration > Configuration > System Configuration > Local Databases), to add a new entry, select Create New Database. To edit an existing entry, select Edit in that entry's row.
