6.6.13.0: Properties of thick servlet redirectors
- Command Line Arguments
- Specifies the command line arguments to pass to the servlet redirector when
it is started.
- Current state
- Indicates the state the servlet redirector is currently in. The next time it
is started, it will try to change to its desired state setting.
- Desired state
- Indicates the state the servlet redirector should have the next time
it is started.
- Environment
- Specifies the environment variables to be used by servlet redirector, and the values
of the variables.
To set variables, click the Environment field to display a dialog box. In
the box, enter variable names and values, clicking the Add button after each one.
- Group ID
- Specifies the name of the operating system group under which to run the servlet redirector.
Note that the operating system group must exist on the machine where the servlet redirector
is to run before the servlet redirector is started. This group must be assigned the necessary
operating system privileges for performing operations such as creating output
files on the local file system. Additional information
specific to operating system
- Group ID in use
- Indicates the group ID the servlet redirector is currently running under.
- Max Connections
- Specifies the maximum number of connections to allow in the queue for the servlet
redirector. These are OSE connections to the Web server.
- Max Connections in use
- Indicates the maximum number of OSE connections allowed between the Web server
and redirector right now.
- Max Startup Attempts
- Specifies the number of times to try starting the servlet redirector before
discontinuing attempts.
- Node
- Specifies the name of node on which the servlet redirector runs.
- Port
- Specifies the port on which the redirector should listen.
- Port in use
- Indicates the port on which the redirector is now listening.
- Process priority
- Specifies the operating system process priority under which to run
the servlet redirector. The lower the number, the greater the importance
of the process. Additional information specific to
operating system
- Process Priority in use
- Indicates the process priority (see above) now in use by the servlet redirector.
- Queue Type
- Specifies the transport to queue requests for:
- OSE (always the queue type if using the thick servlet redirector)
- HTTP
- None
For OSE, you can also specify Transport Type and associated properties. Go
to the thick servlet redirector Advanced properties and click Transport Settings.
Select one of:
- Local pipes
- INET sockets
- JAVA TCP/IP (Not currently supported)
Settings take effect the next time the thick redirector is started.
See the servlet engine tuning section of the
Tuning Guide for suggested
values, typically based on the operating system.
- Servlet Redirector Name
- Specifies a name for the redirector. The name must be unique within the administrative
domain.
- Standard error (stderr)
- Specifies the standard error stream for the operating system.
If the value of this property is set to the null string (""),
the stream is set to the null device.
If this property is set to a relative path name, the path is
relative to the servlet redirector's working directory. Any class of trace output can be
redirected to this file. By default, the output of the fatal, error, and audit
trace classes is sent to this file.
By default, the standard error and standard out logs are written to:
unless a working directory is specified, or the fully qualified path
of the log is specified.
Additional information specific to operating system
- Standard error (stderr) in use
- Indicates the stderr (see above) now in use.
- Standard output (stdout)
- Specifies the standard output stream for the operating system.
If this property is set
to the null string (""), the stream is set to the null device.
If this property is set to a relative path name, the path is
relative to the servlet redirector's working directory.
By default, the standard error and standard out logs are written to:
unless a working directory is specified, or the fully qualified path
of the log is specified.
Additional information specific to operating system
- Standard out (stdout) in use
- Indicates the stdout (see above) now in use.
- Start Time
- Indicates the time at which the servlet redirector was most recently started.
- Trace Log File
- Specifies the file to which to send tracing output. Tracing output is gathered according
to the Trace String specified.
- Trace Log File in use
- Indicates the trace log file (see above) now in use.
- Trace String
- Specifies the servlet redirector component or components to trace. See the
trace help
for instructions for specifying this string.
- Trace String in use
- Indicates the trace string (see above) now in use.
- Umask
- Specifies an octal value that sets the operating system's file creation mask
for the servlet redirector.
The file creation mask specifies permissions that cannot initially be
granted for new files. When a new file is created, the system refuses to grant
the permissions specified in the file creation mask.
For example, a mask of 022 prevents the granting of the write permission to
members of the group that own the file and to all other users who
do not own the file.
A mask of 022 allows the owner to be granted all permissions; in other
words, it leaves the owner's permissions the way the system specifies them.
If the system would otherwise create a file with privilege values of 777
(read, write, and execute permissions
for owner, group, and other), a file creation mask of 022 causes it to create
the file with 755 (all permissions for the owner, but only read and execute
permissions for group and other).
- Legal Values: An integer in the octal range 0 through 0777
- Default: 022
- Umask in use
- Indicates the umask (see above) now in use by the servlet redirector.
- User ID
- Indicates the user ID the servlet redirector should run under.
- User ID in use
- Indicates the user ID the servlet redirector is currently running under.
- Working directory
- Specifies the local directory in which to run the servlet redirector. This directory
is used to determine the locations of input and output files with relative
path names. After starting a servlet redirector, it is recommended that you do not
change the servlet redirector's working directory.
- Working directory in use
- Indicates the working directory (see above) now in use by the servlet redirector.
