Direct RPC is a component that enables RPC clients and RPC servers to connect directly to the EntireX Adapter without the EntireX Broker. This document covers the following topics:
To enable Direct RPC, choose in the EntireX Adapter's administration menu and follow the wizard. The table below gives an overview of parameters to be specified:
| Name | Values | Default | Action | Description | ||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Status | Stopped, Running | Stopped | Start or stop. | Current status of the Direct RPC component. | ||||||||||||
| Logging Level |
|
"Fatal" | Change logging level. | Logging level.
Log file wmentirex.directrpcYYYYMMDD.log is located in folder logs in the Integration Server installation folder. To change the default location, see Adapter Settings. It is not recommended to use "Info", "Debug" or "Trace" in a production environment. |
||||||||||||
| TCP Port Number | Port number | "1971" | Change port number. | TCP listening port for Direct RPC. | ||||||||||||
| SSL Port Number | Port number | - | Change port number. | SSL/TLS listening port for Direct RPC. | ||||||||||||
| Keystore Alias (for SSL) | The alias name of a keystore defined in the Integration Server. | - | Change alias name. | Only needed for SSL. Defined in the IS web admin "Security > Keystore". | ||||||||||||
| Auto Start | Enabled, Disabled | "Disabled" | Enable or disable. | Automatic start of Direct RPC during startup of the Adapter. |
The default encoding of an RPC client or server is the same as the default encoding of the platform used. The table below gives an overview on default and available codepages:
| Platform | Default Codepage | Available Codepages (single byte only) |
|---|---|---|
| Windows/UNIX/Linux | ISO 8859-1 | ASCII codepages |
| IBM mainframe (z/OS, z/VSE) | CP037 | EBCDIC codepages |
| Fujitsu mainframe (BS2000/OSD) | CP273 | EBCDIC codepages |
To specify the encoding of an RPC client or server, see the respective section of the documentation.
The following table gives an overview on monitored objects:
| Item | Description |
|---|---|
| Servers | Number of registered servers. |
| RPC Requests | Number of RPC requests. |
| Socket Connections | Number of plain socket connections (TCP) from RPC clients or servers. |
| Secure Socket Connections | Number of secure socket connections (SSL/TLS) from RPC clients or servers. |
| Direct Connections | Number of direct connections from Adapter services or Adapter Listeners. |
| Calls | Number of calls (including calls such as
logon).
|
| Conversations | Number of conversational calls. |
Notes:
Direct
Connections can be greater than zero even if Direct RPC is
stopped.
The following information is displayed for each service:
| Name | The name of the service |
|---|---|
| Type | "External RPC Server" or "Direct RPC Server". |
| Instances | Number of registered replicates. |
| Wait for Server | Number of client requests that are waiting for a free server to be processed. The percentage (number of calls waiting compared to the total number of calls) is helpful in deciding if further server replicates are necessary. |
| Action | Shutdown (only for external RPC servers). |
Note:
As a prerequisite, at least one server must be registered or listener
enabled.
The following information is displayed for each service:
| Service Name | The name of the service |
|---|---|
| Type | "Listener" or "RPC Server". |
| Name | Name of the Direct Listener or the external RPC server. |
| Host | Host where the external RPC Server is running. |
| Version | Version of the external RPC server. |
| Action | Shutdown (only for external RPC Servers). |
Note:Host, Name and Version can
only be displayed if the RPC server provides this information.
The functionality of Direct RPC as shown on the IS Administration Console's page is available with built-in services in the WmEntireX package. They correspond to the parameters on the IS Administration Console's page. When a service is executed, the signature of the input and output parameters is shown. The following services are available:
pub.wmentirex.directrpc.admin:getAutoStart
pub.wmentirex.directrpc.admin:getIbmMainframeDefaultCharset
pub.wmentirex.directrpc.admin:getKeyStoreAlias
pub.wmentirex.directrpc.admin:getLoggingLevel
pub.wmentirex.directrpc.admin:getSSLPortNumber
pub.wmentirex.directrpc.admin:getSiemensMainframeDefaultCharset
pub.wmentirex.directrpc.admin:getStatus
pub.wmentirex.directrpc.admin:getTCPPortNumber
pub.wmentirex.directrpc.admin:getWindowsUnixDefaultCharset
pub.wmentirex.directrpc.admin:setAutoStart
pub.wmentirex.directrpc.admin:setIbmMainframeDefaultCharset
pub.wmentirex.directrpc.admin:setKeyStoreAlias
pub.wmentirex.directrpc.admin:setLoggingLevel
pub.wmentirex.directrpc.admin:setSSLPortNumber
pub.wmentirex.directrpc.admin:setSiemensMainframeDefaultCharset
pub.wmentirex.directrpc.admin:setTCPPortNumber
pub.wmentirex.directrpc.admin:setWindowsUnixDefaultCharset
pub.wmentirex.directrpc.admin:start
pub.wmentirex.directrpc.admin:stop
In addition, there are 8 services for advanced configuration of the SSL transport:
pub.wmentirex.directrpc.admin:getSSLClientAuthentication
pub.wmentirex.directrpc.admin:getTrustStoreAlias
pub.wmentirex.directrpc.admin:getTLSProtocols
pub.wmentirex.directrpc.admin:getCipherSuites
pub.wmentirex.directrpc.admin:setSSLClientAuthentication
pub.wmentirex.directrpc.admin:setTrustStoreAlias
pub.wmentirex.directrpc.admin:setTLSProtocols
pub.wmentirex.directrpc.admin:setCipherSuites
Note:
Use the setSSLClientAuthentication service to switch on
SSL client authentication. Client authentication requires that a truststore
alias has been set with
pub.wmentirex.directrpc.admin:setTrustStoreAlias. The truststore
alias is defined in the IS web admin Security >
Keystore. Note that the names of the keystore alias and
the truststore alias must be different.
Use the setTLSProtocols service to change the set of enabled TLS protocols. The default is defined by the Java Runtime. Only protocols that are supported
by the Java Runtime can be used. The set of enabled and supported protocols are shown in the log file if the logging level
is set to DEBUG or TRACE. Note that the getTLSProtocols service returns the value previously set by the setTLSProtocols service.
Use the setCipherSuites service to change the set of enabled cipher suites. The default is defined by the Java Runtime. Only cipher suites that are
supported by the Java Runtime can be used. The set of enabled and supported cipher suites are shown in the log file if the
logging level is set to DEBUG or TRACE. Note that the getCipherSuites service returns the value previously set by the setCipherSuites service.
Reliable RPC is not supported.
Command and Information Services (CIS) are not supported. Using this API (directly or through the System Management Hub) can result in errors, or the data returned is incomplete or missing.
An adapter listener and an external RPC server cannot be registered for the same service.
Replicates of external RPC servers must use the same encoding.
EntireX Security is not supported.
ACI applications are not supported. For Natural RPC clients or
servers, Broker ACI is only supported for versions higher than 1. See the
documentation on the ACIVERS parameter in Parameter
Reference in the latest Natural for Mainframe
documentation under
https://empower.softwareag.com/Products/Documentation/default.asp.
