Add Server instance

Restriction: This topic applies only when the Enterprise Server feature is enabled.

Use this page to provide the attributes for an enterprise server (MFES).

Note:

For more information about the configurable attributes of servers, see the chapter Configuration in your Configuration and Administration Guide.

Name

Shows the name of the server.

Server Address

Specify the network address used by the server to accept incoming client requests. The format is:

protocol:ip-address:port

where:

  • protocol is tcp.
  • ip-address is either the text host name or IP address of the server listener. An asterisk (*) indicates that the address is dynamically assigned for the enterprise server when it starts.
  • port is the port value. An asterisk (*) indicates that the port is dynamically assigned for the enterprise server when it starts.

If this network address is not unique in the repository, this might cause enterprise server startup problems.

System Directory

Specify the location for system work files output by the Enterprise Server, such as the console log, and trace and dump diagnostics files. This directory cannot be shared between Enterprise Servers. The default is /var/mfcobol/es/es-name. Where es-name is the name of the enterprise server.

If you specify a directory in this field, that directory must exist; Enterprise Server does not create it for you.

Working Mode

Choose whether this Enterprise Server is to run 32-bit or 64-bit applications.

A 32-bit working mode server can run only 32-bit applications. A 64-bit working mode server can run only 64-bit applications.

You cannot change the working mode of the server once it has been created; you can however, change the mode when you copy or import a server.

Startup Options

Use these fields to specify the server configuration you want when the server first starts up. Any changes you make to these fields while a server is running do not take effect until the next time you start the server.

Shared Memory Pages

Specify the number of shared pages in memory to be reserved for all the processes that run in the Directory Server. Each page is 4KB long.

Service Execution Processes

Specify the number of service execution processes that are to be started at server initialization.

Shared Memory Cushion

Specify the number of 4KB pages that should be reserved from the shared memory pages to allow the server to continue processing when the shared memory allocation is too small for the operational requirements of the server. The range is 1 through the number of shared memory pages.

Trace Table Size

Specify the number of entries the trace buffer can hold before it wraps back to the start. (The trace buffer is also written to disk at this point if you checked Auxiliary Trace Active.) A value of 2 means that there is space for only one entry, and if you checked Auxiliary Trace Active each entry is written straight out to disk. Each entry is 24 bytes long.

Local Trace Size

Specify the number of entries the local trace table can hold before it wraps back to the start. A value of 0 (zero) means that no local trace table is allocated. Each service execution process has its own local trace table. Each entry is 24 bytes long.

Maximum Diagnostics File Size

Specify the maximum size of the auxiliary trace and dump file in kilobytes. A value of 0 (zero) means that the file can grow to the maximum file size supported; 4GB.

Requested Licenses

Specify the number of licenses this enterprise server requires.

Cold Start Diagnostics File

Check this to indicate that the auxiliary trace and dump files are to be deleted when the server starts.

Dump on System Abend

Check this to indicate that the server should produce a dump if one of its own processes, such as a service execution process, terminates abnormally. The dump information can help you to determine the cause of the abnormal termination

Auxiliary Trace Active

Check this to indicate that trace records are to be flushed to disk before the trace table is overwritten. You should do this only if you have adequate disk space available, since the file can become very big very quickly. If you have a high-activity system use this field in conjunction with Maximum Diagnostics File Size to limit the disk usage. Writing out to a file also degrades performance.

Show Local Console

Check this if you want to see a text window containing enterprise server messages while the server is running. The messages are written to a file called console.log, in the directory specified in System Directory. You can see the text window only on the machine running the enterprise server. The system messages are also available on the Enterprise Server Console page.

Trace Flags

Use these flags to control what information is written to the trace file for this server. Any changes you make to these fields while a server is running take effect immediately.

Task Control

Check this to indicate that the server is to trace its task control component.

Storage Control

Check this to indicate that the server is to trace its storage control component.

Table Management

Check this to indicate that the server is to trace its table management component.

Application Container

Check this to indicate that the server is to trace its application container component.

Request Handler

Check this to indicate that the server is to trace its request handler component.

RM Interface

Check this to indicate that the server is to trace its resource manager interface component.

Communications

Check this to indicate that the server is to trace its communications component.

Exit

Check this to indicate that the server is to trace user and system exits.

Configuration Information

Specify textual configuration information that determines the start-up and run-time behavior of the server. Optional. For details of the valid entries, see the section Configuration Information in the chapter Servers in your Configuration and Administration Guide.

Description

Specify a text description of the server, for example, its purpose and owner. Optional.
