Options for the Metadata Server Invocation Command

Optional Parameters

The following parameters invoke optional functionality in a SAS Metadata Server in all host environments:

The access control parameter AUTHPROVIDERDOMAIN:

AUTHPROVIDERDOMAIN=(provider:domain-name)

specifies an alternative authentication provider. When the AUTHPROVIDERDOMAIN parameter is omitted from the metadata server start command, the metadata server uses host authentication to authenticate users. AUTHPD is an alias for AUTHPROVIDERDOMAIN. For usage information, see Direct LDAP Authentication in the "Authentication Mechanisms" chapter of the SAS Intelligence Platform: Security Administration Guide.

Note: In UNIX operating environments, you must insert an escape character before each parenthesis. For example:

-authproviderdomain = \(ADIR:MyDomain\)

The OBJECTSERVERPARMS parameters:

THREADSMIN=minimum-number-of-threads

specifies the minimum number of threads in the server's thread pool. When the number of threads falls below this number, IOM mechanisms automatically create new threads. TMIN is an alias for THREADSMIN. THREADSMIN and THREADSMAX are set in conjunction with the MAXACTIVETHREADS server configuration option.

Default:

By default, the server uses this formula to compute the minimum number of threads:

MAX(5,((number-of-processors * 2) + 1))

This means that the value is set to either 5 or to ((number-of-processors * 2) + 1), whichever is greater.

THREADSMAX=maximum-number-of-threads

specifies the maximum number of threads in the server's thread pool. When the number of threads exceeds this number, IOM mechanisms automatically delete threads. TMAX is an alias for THREADSMAX.

Note: It is recommended that TMIN=TMAX. [cautionend]

THREADSMIN and THREADSMAX are set in conjunction with the MAXACTIVETHREADS server configuration option.

Default:

By default, if no value is specified for maximum number of threads, it is set to the computed value of THREADSMIN.
