Options for the Metadata Server Invocation Command R Additional UNIX Parameters 261<br />

TRUST<strong>SAS</strong>PEER=trustedPeers.xml<br />

enables peer servers used by a <strong>SAS</strong> metadata client to connect to the<br />

metadata server using the credentials of the connecting client. <strong>SAS</strong><br />

applications that require this support will state the requirement in their<br />

documentation. For more information, see “Setting up Trusted Peer<br />

Connections for <strong>SAS</strong> Sessions” in the <strong>SAS</strong> Integration Technologies: Server<br />

Administrator’s <strong>Guide</strong> at<br />

THREADSMIN=(number-of-processors *2)+1<br />

specifies the minimum number of threads in the server’s thread pool. When<br />

the number of threads falls below this number, IOM mechanisms<br />

automatically create new threads. TMIN is an alias for THREADSMIN.<br />

Note: It is recommended that TMIN=TMAX. R<br />

THREADSMIN and THREADSMAX are set in conjunction with the<br />

MAXACTIVETHREADS server configuration option.<br />

THREADSMAX=(number-of-processors *2)+1<br />

specifies the maximum number of threads in the server’s thread pool. When<br />

the number of threads exceeds this number, IOM mechanisms automatically<br />

delete threads. TMAX is an alias for THREADSMAX.<br />

Note: It is recommended that TMIN=TMAX. R<br />

THREADSMIN and THREADSMAX are set in conjunction with the<br />

MAXACTIVETHREADS server configuration option.<br />

Additional Windows Parameters<br />

A Windows server also requires the following parameters:<br />

the system administration parameter MEMSIZE=value<br />

specifies the amount of memory to allocate to the metadata server process. We<br />

recommend a value that allows the operating system to set the memory limits on<br />

the server. This can be accomplished by setting a value of 0 (zero), MIN, orMAX.<br />

the display parameter NOSPLASH<br />

suppresses the display of <strong>SAS</strong> logo and copyright information when invoking the<br />

<strong>SAS</strong> session.<br />

Additional UNIX Parameters<br />

A UNIX server requires the following parameter in addition to those described in<br />

“Recommended Parameters for All Host Environments” on page 259:<br />

the system administration parameter MEMSIZE=value<br />

specifies the amount of memory to allocate to the metadata server process. We<br />

recommend a value that allows the operating system to set the memory limits on<br />

the server. This can be accomplished by setting a value of 0 (zero), MIN, orMAX.
