cmqc.pas file need to align with IBM MQ 9.2

Problem Statement :

We are upgrading from IBM MQ 7.5 to IBM MQ 9.2 with code written in Delphi Programming language.

Which doing upgrade, following IBM MQ configuration added.

1. Username and Password to connect MQ

2. SSL Certification.

Analysis and Reference :

As per our analysis, Current written Delphi programming code "cmqc.pas" referencing 'MQIC.DLL' under IBM MQ 7.5 not working for IBM MQ 9.2

We might need to align records with upgraded versionof IBM MQ 9.2

For alignment, You can refer following IBM MQ team provided

Reference Link : https://www.ibm.com/docs/en/ibm-mq/9.1?topic=mqcno-visual-basic-declaration

Sample Delphi code for MQ connection :-

//

function TmskMQQueueMgr.ConnectX : boolean;

var

MQMgrName: MQCHAR48;

ClientConn : MQCD;

Connect_Options : MQCNO;

SecOptions : MQCSP; //SMQ

UserName, Password : PWideChar;

strUserName, strPassword : string;

begin

if FConnHandle <> 0 then

Disconnect;

ClientConn:= MQCD_DEFAULT;

Connect_Options := MQCNO_DEFAULT;

SecOptions := MQCSP_DEFAULT;

strUserName := 'metsp';

strPassword := 'QaCTXsGnMCh5azuLrheu5?jL';

UserName := Addr(strUserName);

Password := Addr(strPassword);

SecOptions.CSPUserIdPtr := @UserName; //SMQ

SecOptions.CSPUserIdLength := StrLen(UserName);

SecOptions.CSPPasswordPtr := @Password ; //SMQ

SecOptions.CSPPasswordLength := StrLen(Password);

Connect_Options.SecurityParmsPtr := @SecOptions; //SMQ

SetMQString(MQMgrName, FQMgrName, SizeOf(MQMgrName));

SetMQString(ClientConn.ConnectionName,FconnectionName,255);

SetMQString(ClientConn.ChannelName,FchannelName,MQ_CHANNEL_NAME_LENGTH);

Connect_Options.ClientConnPtr := @ClientConn;

Connect_Options.Version := MQCNO_VERSION_6;

try

if Assigned(FBeforeConnect) then

FBeforeConnect(Self);

MQConnX(@MQMgrName,@Connect_Options,@FConnHandle, @FCompCode, @FReason);

CheckError;

if Assigned(FOnConnect) then

FOnConnect(Self);

except

end;

Result := Connected;

end;

//

Please find cmqc.pas file attached with case for further analysis.

Analysis of problem :

According to us, we need to update cmqc.pas file with parameters feasible to MQ 9.2 and send it to MQConnX function

(with Username, Password & SSL certification option).

Where we used following parameters provided under cmqc.pas file

UserIdentifier:MQCHAR12; //* User identifier */

Password:MQCHAR12; //* Password */

and send it to "MQConnx" function, But it is not able to connect.

Following error coming

MQRC_HCONN_ERROR (2018)

Please let us know , possible guidance to connect MQ Server with SSL certificate , Username & Password.
