IOM Server Appender
writes log messages from any IOM server (for example, a SAS Metadata
Server, a SAS OLAP Server, or a SAS Stored Process Server) to a volatile
runtime cache. The contents of the cache are available for display
on the
Log tab of SAS Management Console.
For more information, see “Use the Log Tab in Server Manager”
in the
SAS Intelligence Platform: System Administration Guide.
If you perform a planned
deployment, then IOMServerAppender definitions are included in the
logging configurations for most of your SAS servers. Follow these
best practices when modifying these definitions:
-
You can adjust the MaxEntries value
to capture a larger or smaller number of messages for display.
-
Do not change the message layout.
Changing the message layout could cause messages to be captured incorrectly.
Note: A location for temporary
files must be defined on the host operating system. If a location
has not been defined, then the process that is being logged fails
with the following message:
Error creating IOMServerAppender
index cache. The location required for storing temporary utility files
does not exist.
If a location for temporary files
is not already defined, use one of the following procedures to define
it:
-
On Windows systems, define the
TEMP environment variable.
-
On UNIX systems, create the directory
/tmp
.
-
On
z/OS systems, create the directory
/tmp
if you are using a UNIX file system (UFS); or
submit the following TSO command:
ALLOC UNIT(SYSDA) BLOCK(8192) SPACE(1280,1280)
