VNC0502E

REXX INIT: NCRXL01 REXX environment initialization failed; RTC=return-code; RSC=reason-code; CPB=cpb-address

The VNAC REXX loader program, VNCRXL01, attempted to create a REXX environment but the request failed. RTC and RSC are the return and reason codes returned by the IRXINIT call.

Destination: VNCLOG.

Action: Review the agent logs for other messages that may indicate why the request failed. The agent will continue without the use of the VNAC REXX loader, which may impact performance if you normally run with it enabled. Contact SDS Technical Support for additional assistance.

VNC0501D

VNCRXM00: exec-name IRXINIT(INITENVB) successful; RTC=hex-return-code; ENV=envb-address; CPB=cpb-address

Debug message issued by VNCRXM00, the main REXX processing program, after it successfully initializes a new REXX language environment to run the current REXX exec.

VNC0500D

VNCRXM00: REXX exec processing started; CPB=cpb-address

Debug message issued by VNCRXM00, the main REXX processing program, when it starts. VNC0500D and VNC0510D bookend all the messages issued during the processing of a single exec.

VNC0426I

taskname: Reloading REXX environment.

A MODIFY vnac,RELOAD,REXX command was received. The dispatcher is reinitializing the REXX environment of the named task.

Action: None. This is an informational message.

VNC0425I

REXX storage: Used RM31=decimal-K-bytesK, RM24=decimal-K-bytesK; Requests=request-count, Failed=request-count

Informational message issued by VNCINI00, the program that runs the OBEYFILE exec during agent initialization, and VNCCPR01, the program that runs all REXX execs after the agent has finished intializing.

This message is displayed after an exec has completed execution, following message VNC0411I, to show the maximum amount of rmode 31 and rmode 24 memory used by the exec.

The request-count is the total number of requests from REXX to obtain and free blocks of memory. Normally, this should be an even number. It may be an odd number if a request fails and REXX issues a request for a smaller amount of memory that is accepted.

Normally, the failed request-count will be zero. If it is not, message VNC0961E will have been previously issued to show which rmode memory limit was exceeded.

When UseREXXLoader is set to Yes, RM24 is typically OK. However, even when the VNAC REXX loader is used, you may see some exec tasks running and below-the-line storage being used. Typically, these will be the initial obeyfile task and any exec that runs automatically at startup.

Until the initial obeyfile has been processed, the agent will default to running without the use of the VNAC REXX loader. Thus, these early tasks will load their own exec locally and cause REXX to obtain below-the-line storage for the I/O buffer. When these execs have ended, the REXX environment will be deleted and the associated below-the-line storage will be released. As a result, these execs do not impact the address space below-the-line storage usage in any significant manner; any such usage is temporary.

Action: Assuming the exec does not have an error, the corrective action is to increase the memory limit for the corresponding rmode using the RexxEnvLimit global configuration statement.

VNC0424D

allocating|opening|closing dataset dataset-name; DD=ddname

VNAC generates this diagnostic message when it handles a browse request to retrieve a dataset. The message shows the command identifier, function request, dataset name, and DDName.

VNC0423E

The view feature is not configured on this agent.

The VNAC agent is configured to send zero (0) lines of a dataset to the server and client.

Action: In the agent configuration member, re-set the ViewLimit parameter.

VNC0422E

VNAC cannot process the input dataset. An abend occurred during read processing

VNAC detected an abend while reading a dataset for the View feature. VNAC recovers and issues this message to the log and to the user at the browser.

Action: This message can be issued if an invalid dataset was requested. Ensure the dataset is a DSORG=PS dataset with RECFM=F or V, or a PDS member. If the problem persists, contact SDS Technical Support.

VNC0421E

VNAC cannot process the input dataset because its DSORG is not PS

A dataset was passed to the View datasets feature that had a dataset organization (DSORG) that was not PS. VNAC only supports DSORG=PS datasets, or PDS members.

Action: Specify a valid dataset name or PDS member name.

VNC0420E

Dataset dataset-name allocation failed; retc=return-code, rsnc=reason-code

The dataset View feature was used to request a dataset and the dataset could not be allocated. This message is sent to the VNAC client user.

Action: Look up the return and reason codes to determine the cause of the error. (Dynamic allocation return codes are documented in the IBM manual MVS Authorized Assembler Services Guide.) Correct any errors and retry the request.
