Virtual Machine General Configuration

To set the Virtual Machine general configuration, do the following:

1. Click the configuration for which you want to configure the settings. For example, Base.

2. On the Virtual Machine Settings tab, click General.
   The configuration page appears with default settings.

3. In addition to the basic configuration that exist on all platforms, there are few parameters which are platform-dependent. You may need to consider (set the configuration specifically to handle) these differences whilst you modify the configuration. The following table describes the fields that can be configured.

   Field Name	Description
   Client Connection Timeout	The application time-out period can be used to set inactivity time-out (in seconds) for reads. This signifies the time in seconds where the client will wait for connection to Virtual Machine before it times out. Default is 30 seconds, 0=none.
   Max Users	Enter the maximum number of concurrent sessions permitted on PROIV Windows server. The default value is 10.
   Standard Validation Date Century Format	Turn ON the slider to set the year in four digit format in Standard Validation. The data century format determines how a date field is displayed. The default value is set to OFF which signifies the year in two digit format.
   Date Century Format	Turn ON the slider to enter the date value in four digit year format. It determines how a date value must be validated whilst entering using the keyboard. The default value is set to OFF which signifies the year in two digit format.
   Enable Umsg Delay	Turn ON the slider to process the delay time set in umsg. The operand 2 in umsg is the delay, it will be ignored if this is not set to true.
   Print Path	The print output can be directed to a file and output at this path. It doesn't have to go to a printer directly (Windows Only).
   Home Directory	It is a directory that serves as a repository for all configuration files, directories of PROIV Virtual Machine. For example, the default path on a Windows machine is "&$@~PROPATH" and on UNIX machine it is "/opt/&$@~PROPATH". You can change it, if required.
   Run Type	Select either DEVELOPMENT or RUN-TIME mode.
   Enable GUI	Turn ON the slider to run PROIV in GUI mode.
   Temp Directory	The Virtual Machine temporary directory.
   Validate Username	Turn ON the slider to validate public username on PROIV Windows server.
   User Domain	Domain name is used to validate login information on PROIV Windows server.
   Logon Type	Select a logon type such as InteractiveInteractive, BatchBatch or NetworkNetwork on PROIV Windows server. Network: This logon type is intended for high performance servers to authenticate plain text passwords. The LogonUser function does not cache credentials for this logon type. Batch: This logon type is intended for batch server, where processes may be executing on behalf of a user without their direct intervention. This type is also for high performance servers that process many plain text authentication attempts at a time, such as mail or web servers. Interactive: This logon type is intended for users who will be interactively using the computer, such as being logged on by a terminal server, remote shell, or similar process. This logon type has the additional expense of caching logon information for disconnected operations; therefore, it is inappropriate for some client/server applications, such as a mail server.
   Mandatory Profile	Turn ON the slider to set the mandatory profile on PROIV Windows server.
   Secure Connection	Turn ON the slider to set the secure connection on PROIV Windows server.
   Use EBCDIC	Turn ON EBCDICEBCDIC to use 8 bit EBCDIC encoding. Returns the EBCDIC equivalent of an ASCII string. Purpose The EBCDIC routine returns the EBCDIC equivalent of an ASCII string. Syntax variable = EBCDIC(operand) Operation operand is any valid alphanumeric constant, variable, or expression. It can be between 0 and 250 characters long. Remarks The returned value is the same length as the operand and contains the translated characters.
   Terminal
   Type	The terminal type for PROIV session. The default value is 'GUIDEV'.
   Id	The identifier of PROIV terminal with maximum length 8 characters.
   Mixed Case	Turn ON the slider to allow mixed case (UPPER and lower) messages.
   XSL
   Separate Transform	Turn ON the slider to set for separate transform process (UNIX Only).
   Path	The location of PROIV XSL file.
   Task
   VM Session Idle Timeout	The duration in seconds before idle Virtual Machine session is terminated.
   Enable Non-Input Screens	Turn ON the slider to permit screens functions that require no input to execute in task mode. When OFF any attempt to execute a screen function in task mode results in an exception.
   Umsg Output
   To Log	Turn ON the slider to display the user message output to log when running in task mode.
   Msg Output
   To Log	Turn ON the slider to display the message output to log when running in task mode.
   UNIX
   User ID	The UNIX user id for the application connector web app process (if non-zero.)
   Group ID	The UNIX group id for the application connector web app process (if non-zero.)

Virtual Machine Network Configuration

To set the Virtual Machine network configuration, do the following:

1. On the Virtual Machine Settings tab, click Network.
   The configuration page appears with default settings.

2. Modify the configuration as required. The following table describes the fields that can be configured.

   Field Name	Description
   Listener
   Interactive - applicable for only Windows operating system.
   Enable No Delay	Turn ON the slider to enable NO DELAY feature on TCP/IP Socket. The default value is True. When No Delay is set to false, a TCP/IP Client does not send a packet over the network until it has collected a significant amount of outgoing data. However, if you need to send very small amounts of data or expect immediate responses from each packet you send then you can set to OFF. Use it as per the importance of network efficiency and application requirements at user interaction level.
   Port	The standard connection port on which the service will listen for network connections. The default port number is two digit current version (as found from &$@~PROPATH) suffixed with '023'. In most cases, it is not necessary to change this value.
   Secure Port	The secure connection port. The default port number is two digit current version (as found from &$@~PROPATH) suffixed with '024'.
   Task
   Enable No Delay	Turn ON the slider to enable NO DELAY feature on TCP/IP Socket. The default value is True. When No Delay is set to false, a TCP/IP Client does not send a packet over the network until it has collected a significant amount of outgoing data. However, if you need to send very small amounts of data or expect immediate responses from each packet you send then you can set to OFF. Use it as per the importance of network efficiency and application requirements at programmatic level.
   Port	The port number exposed for task connections. The default port number is two digit current version (as found from &$@~PROPATH) suffixed with '833'. For UNIX operating systems, if the port is changed to a different port number to the application connector vm host port then a confirmation dialog will be displayed when the configuration is saved, asking whether the application connector vm host port should also be updated to the same number.

3. Click Submit.
   The configuration is saved.

Virtual Machine Database Configuration

To set the Virtual Machine database configuration, do the following:

1. On the Virtual Machine Settings tab, click Database.
   The configuration page appears with default settings.

2. Modify the configuration as required. The following table describes the fields that can be configured.

   Field Name	Description
   Default Database
   PROPATH	The location of PROIV bootstrap files. For example, the default path on a Windows machine is "&$@~PROPATH" and on UNIX machine, it is "/opt/&$@~PROPATH".
   PRODATA	The location of PROIV application files. For example, the default path on a Windows machine is "&$@~PROPATH" and on UNIX machine, it is "/opt/&$@~PROPATH".
   Enable Rollback	Turn ON the slider to enable transaction rollbackrollback, if an error occurs. There are several situations where a rollback is automatically performed in order to help protect the integrity of an application database. When the operator uses the Break key and the interrupt is not disabled. When a timeout occurs while waiting for operator input. When it can be detected that the connection to the operator's terminal is lost. When an attempt to commit fails. If an individual PROIV process aborts, a rollback is performed either by PROIV itself or by DBMS/file system processes. In environments where the rollback must be performed by PROIV, it will occur only for externally requested, 'controlled' aborts. When an attempt is made to regen a function within a transaction. When a PROIV runtime error occurs, it may impact application data integrity. Deadlocks and lock timeouts give rise to errors in this category (and a DBMS or file system may force a rollback for these cases anyway). In all these situations, the current PROIV function is terminated. In cases 4 through 7 control is passed to a rollback link function to help the application developer or end-user determine the cause of the problem. The rollback link function is stored in the system variable @RFUNCT, which can be altered in logic. The initial setting of this variable is the string '@RFUNCT' and an example function of this name is supplied with PROIV. In the case of write errors, specifically errors 018 (error in writing file) and 019 (error in deleting record in file), it is possible to prevent an automatic rollback by suppressing the error. This can be done using the DSELF statement in after-write-error logic. The @SYSERRsystem variable can be tested in after-write-error logic in order to detect specific errors (for example a duplicate key) but its contents will depend on the file system or DBMS in use. Failure of a rollback is an error with severe implications for application data integrity. In the unlikely event that this problem occurs, the PROIV session is terminated immediately with a warning message of the form Process aborting due to Rollback failure.
   Ignore Alternate Indices	Turn ON the slider to ignore alternate indices.
   Driver General Database Settings
   Display Lock Message	Turn ON the slider to display a message when the records are locked during an update operation.
   Display Error Message	Turn ON the slider to display a message when the transaction generates an error.
   Add Lock Hints	Turn ON the slider to automatically add Lock Hints in Full Function SQL Statements. N.B. operation of this option may be affected by settings in the Advanced SQL Server Configuration see expert users
   Cursors	String valuesString values of 10 to 128. The default value is AUTO. Valid values are 10 – 128 or AUTO - This specifies the number of open cursors to be used per connection.  Generally the higher the number of cursors the better the performance but there is a resource overhead on the database using more cursors.  It is impractical to just use one cursor.
   Timeout	The database timeouttimeout in seconds. These three PROIV Environment Variables must be enabled for SQL Server to use the enhanced record lock mechanism. The settings for SQLTIMEOUT are as follows: SQLTIMEOUT      -1      - Report record lock immediately the SQL command is issued to the database SQLTIMEOUT       0      - Block indefinitely until the database releases the record lock SQLTIMEOUT     >0      - Block for the specified amount of seconds before raising a record lock message @SQL_TIMEOUT defined in PROIV Logic has higher precedence over SQLTIMEOUT To ensure the break key works LOCKED_ROWS_RETURNED=Y and SQLSERVE_TABLE_LOCKING =Y must be defined.  If SQLSERVE_TABLE_LOCKING is not specified, it is enabled by default from PROIV v6.1.57.0 release onwards.
   Enable SQL Alarm	Set to enable "Waiting for SQL Database" messages (UNIX Only).
   Oracle Configuration
   OCI8 Cache	Select the caching model. Refer to OCI CachingOCI Caching for more information. The Oracle Call Interface (OCI) defines the APIs that PROIV can use to add, retrieve and manipulate information stored in the Oracle database. PROIV 'V' with two digit current version (as found from &$@~PROPATH) accesses Oracle database using Oracle Call Interface routines. The overall performance is improved with the use of the OCI routines in PROIV 'V' with two digit current version (as found from &$@~PROPATH) by replacing the obsolescent OCI routines. PROIV provides "OraProcLogon" routine for logging onto an Oracle database which you can replace with your routine to customize the logon procedure based on your business requirement. OCI Caching In PROIV, the "ORA_CACHE" global logic call must be executed prior to any file access on the file that needs to be cached. You must add the proiv file name associated with tables to the cached-files list by calling the global logic ORA_CACHE<filename>. Note: PROIV v8 onwards operates with Oracle 9.2 and above. Note: By default, Caching is disabled.   'Caching Enabled' to enable caching and 'RowNum Caching Enabled' indicates caching is enabled where select statement uses ROWNUM. If an Update or Report cycle is defined as One Time Cycle, then the OCI interface will cache the primary file’s row returned. Concurrently, this is true for all secondary file reads, whether the cycle is called as One Time or Many Time cycle, since all secondary file reads are in effect as ‘One Time’. It records when a full key read is executed. Caching is performed for the files in Look mode (L), transparent SQL, and not for any type of full-function SQL . To use the Oracle caching feature, the database and tables which require their result set to be cached, must be configured to enable result set caching by the oracle database administrator.

Virtual Machine Licensing Configuration

Licensing configuration helps you to setup licence to control the features and functionality that are available in PROIV.

To set the Virtual Machine licensing configuration, do the following:

1. On the Virtual Machine Settings tab, click Licensing.
   The configuration page appears with default settings.

2. Modify the configuration as required. The following table describes the fields that can be configured.

   Field Name	Description
   Serial No	The licence server serial number, used to determine the licence group from which a licence is granted. It is the group identifier that uniquely identifies a set of licences on a server.
   Customer
   Customer Name	The customer name is displayed.
   Server
   Host Name	The host name for licence server. The default value is the PROIV server name.
   Port	The port number for licence server. The Licence Server accepts requests from PROIV components on this port. This can be altered to avoid port clashes. The default value is 5439.
   RetryRetry Retry Licence Acquisition Repeated retries to acquire a licence occurs when the initial attempt fails for any reason. When there is a licence failure, the PROIV Virtual Machine sleeps for the specified interval and then retries to acquire the licence. This is repeated until the duration period has been exceeded. If the final attempt to acquire the licence fails (which occurs after the duration has expired), the session terminates. This Retry mechanism is controlled by the following parameters LICENCE_SERVER_RETRY_INTERVAL - to specify the minimum interval between retries, in seconds. LICENCE_SERVER_RETRY_DURATION - to specify the minimum time for retries to be attempted for, in seconds. If LICENCE_SERVER_RETRY_INTERVAL is not specified or it is set to a non-numeric string, then there is no attempt to retry for a licence and failure on the first attempt results in the session being rejected. An interval time must be specified for this facility to be enabled. The minimum value that may be specified for the interval is 5 seconds and the maximum is 60 seconds. If the facility is not enabled then the LICENCE_SERVER_RETRY_DURATION variable is ignored and has no effect on the system. If LICENCE_SERVER_RETRY_DURATION variable is not specified, or it is set to a non-numeric string, then the duration defaults to 10 times the specified interval. The minimum value that can be specified for the duration is the time specified for the interval plus one second, and the maximum is 3600 seconds (1 hour). The LICENCE_SERVER_RETRY_DURATION variable can be set to zero which has a special meaning. If the LICENCE_SERVER_RETRY_DURATION is set to zero then there is no limit on the duration of the retries. This results in attempts to get the licence being repeated forever and the session never fails, but the session will not start up until a licence has been obtained. If this option is used with incorrect licensing details then the PROIV Virtual Machine may loop forever. If a value, for either variable, is specified that is out of range (except for 0 for LICENCE_SERVER_RETRY_DURATION), then the nearest limit is used. For example, if a value less than the minimum is specified, then the minimum value is used, if a value greater than the maximum is specified, then the maximum is used.
   Interval	Specify the minimum interval between retries, in seconds. When an attempt to get a licence fails, the PROIV Virtual Machine sleeps for the specified interval and then retries to acquire the licence. The default interval is 5 seconds.
   Duration	Specify the minimum time for retries to be attempted for, in seconds.

Virtual Machine Diagnostics

Tracing is a low-level debugging feature that can be useful for analyzing system crashes or unusual behavior when PROIV is executing. The output generated can greatly assist PROIV Support to resolve customer issues more efficiently.

To set the Virtual Machine Diagnostics configuration, do the following:

1. On the Virtual Machine Settings tab, click Diagnostics.
   The configuration page appears with default settings.

2. Modify the configuration as required and click Submit. The following table describes the fields that can be configured.

   Field Name	Description
   Trace File Path	The folder into which the trace files are written. A trailing slash is required. This folder acts as Automatic Diagnostic Repository.
   Tracefile Max Size	The maximum file size for the trace. When the file size reaches this maximum, trace events are no longer recorded in this file. Enter the file size in MB. The maximum allowed value is 50 and minimum size is 0 (denotes unlimited file size). If not set, then the default value is set to 0.
   Max Files/VM	The maximum number of trace files that can be created for the current session. You can create a minimum of 1 file to a maximum of 20 files per session. The tracing starts with the first trace file and when it reaches its maximum size specified by TR_MAX_FILE_SIZE then it will rollover to the second trace file. This process will continue until the number of trace files generated reaches the max set files per session specified by TR_MAX_FILES_PER_VM. In such a case where the last trace file reaches its maximum size, then the oldest trace file is reused to enable tracing to continue and the rollover process is repeated. If TR_MAX_FILES_PER_VM is not within the predefined range of minimum or maximum values, then these parameters will default to either the min (1) or max (20) values depending on whether the set value is less than the minimum value or greater than the maximum value. The trace file size is limited using the configuration parameter, TR_MAX_FILE_SIZE. If only TR_MAX_FILE_SIZE is specified and no mention about TR_MAX_FILES_PER_VM, then TR_MAX_FILES_PER_VM will take the default value "1". The tracing starts and a new trace file is created and the logs are written until its size reaches set max file size. When it exceeds the max file size set in TR_MAX_FILE_SIZE, then the tracing log is written from the beginning of the trace file. In this case, the timestamping will implicitly be turned on.
   Trace Levels
   All	If this is defined it overrides all other trace categories and sets them to this level.
   Caching	The trace level runtime cache.
   Environment	The trace level for the environment settings processing . Suggested level is 4.
   File	The trace level for the file system access. Suggested level is 8.

   Misc	The trace level for miscellaneous items. Suggested level is 9.
   Profiler	The trace level for profiler.
   Property accesses	The trace level to monitor properties.
   Recovery	The trace level for file recovery (file commit, rollback processing). Suggested level is 3.
   Report	The trace level for report output. Suggested level is 4.
   Screen Output	The trace level to store output of trace data for screen.
   SQL	The trace level for the SQL file interfaceSQL file interface. Suggested level is 3. The SQL trace option is used to trace the internal SQL code. This includes information such as the generated SELECT / UPDATE / etc. statements. This option is typically used along with the General Trace option TRACEFILE, which shows the higher level code (such as the contents of the current record being read / written). This trace option is actually one of the General Trace options, called TRACESQL. There are currently problems with the level settings for TRACESQL. At present, this violates the standard used in all other trace areas, in which a higher level of trace causes more information to be displayed. For TRACESQL, some information displays only if you set level = 2, or level = 9. Other information is only displayed for level = 3, or level = 8 or greater. Most of the Microsoft SQL Server trace is only displayed for level = 8 exactly. So currently the recommended trace levels are: Generic SQL layers (common to all SQL databases). Level = 2 or 3 for some specific SQL code areas; 15 for all. Oracle Driver. Level = 8 or greater for most messages, though some are only displayed for level 3 exactly. DB2 Driver. Level = 3 for main DB2 trace code, 8 or 9 for most / all. MS SQL Server Driver. Level = 8 exactly. This displays all information. In general, level = 3 produces a lot of trace information, and should be tried first. If this is not enough, try level = 8 or 9, depending on which database driver you are using. However, with Oracle you will lose a lot a trace information if you do not use level 3.
   Stack	The trace level for stack tracing.
   Task	The trace level for the P4API bus and tasks interface. Suggested level is 9.
   Task Admin	The trace level to trace task administration operations.
   User	The trace level for the user (developer) application information. Suggested level is 3.
