OpenLink Multi-Tier Server-Side Components (Unix) for Progress

Aims and Intentions

This guide is intended to enable competent system administrators to install and configure OpenLink Multi-tier client side components on UNIX-like operating systems (e.g., Solaris, AIX, HP-UX, Linux, FreeBSD) in a few steps as possible.

This guide does not explain any of the non-pertinent features encountered along the way. Such explanations may be found in the full documentation.

Prerequisites

  • You MUST be proficient in using a Unix shell. bash is preferred; sh, zsh, ksh, csh, or tcsh are all usable.
  • You MUST be proficient in using a Unix editor such as vi or emacs.
  • You MUST have read and execute permissions on a full installation of the Progress or OpenEdge database, or on an installation of Progress® Client Networking (for SQL-89 Agents) or Progress® SQL-92 Client Access (for SQL-92 Agents).

Installation

  1. Log onto the machine and create a suitable OpenLink installation directory ($OPENLINK_INSTALL), such as /opt/openlink/.
  2. Copy all OpenLink component installation files to $OPENLINK_INSTALL. At a minimum, these will include the OpenLink Request Broker (oplrqb.tgz), an OpenLink Database Agent for your respective target database (e.g., prs100_mv.tgz), and an license file (oplrqb.lic).
  3. Install using the "install.sh" shell script -- 


    #sh install.sh

  4. You should take care to enter correct information when prompted pertaining to ports, passwords, etc., and write these down for future use.
  5. The installation should finish without error.

Licensing

OpenLink Multi-Tier licensing is handled on the server side so you should place the OpenLink license file (oplrqb.lic) in the $OPENLINK_INSTALL/bin/ directory.

Configuration

Progress requires a small amount of additional environmental configuration in the OpenLink Request Broker session rulebook ($OPENLINK_INSTALL/bin/oplrqb.ini) --

  1. Open the rulebook file, $OPENLINK_INSTALL/bin/oplrqb.ini, with a suitable text editor such as vi.
  2. Locate and edit the [Environment xxxxx] section corresponding to your target database so as to ensure that any relevant environment variables pertaining you your system and target database are correct. NOTE: You may need to consult with your database administrator to verify these. The following example shows environment sections for a Progress 9 SQL-89 / 4GL agent, and a Progress 10 SQL-92 agent --
    Progress 9 (SQL-89/4GL) 


    [Environment PROGRESS91E]
DLC                 = /dbs/progress/v9.1e
PROCFG              = /dbs/progress/v9.1e/progress.cfg
;TABLEVIEW           = tableview.dat ; Full path to file generated by setup.p
;TABLEVIEW_QUALIFIER = Y       ; Add owner information to select statement
;INSERT_LOGICAL      = Y       ; Rewrite character TRUE/FALSE to logical
;UPDATE_LOGICAL      = Y       ; Rewrite character TRUE/FALSE to logical
;MIN_FIELD_LEN       =         ; Min length for char field or expression
;MAX_FIELD_LEN       =         ; Max length for expression
;EXPR_PRECISION      = 15      ; Fixed precision for numeric expressions
;EXPR_SCALE          = 2       ; Fixed scale for numeric expressions 
CURSOR_SENSITIVITY  = LOW     ; Set to HIGH after loading oplrvc.sql

[Environment PROGRESS100SQL]
DLC                 = /dbs/progress/v10.0a
PROCFG              = /dbs/progress/v10.0a/progress.cfg
CURSOR_SENSITIVITY  = LOW      ; Set to HIGH after loading oplrvc.sql
LD_LIBRARY_PATH     = /dbs/progress/v10.0a/lib
SHLIB_PATH          = /dbs/progress/v10.0a/lib
LIBPATH             = /dbs/progress/v10.0a/lib
;SQL_CLIENT_CHARSET  = UTF-8    ; Uncomment for Unicode connection


Start the OpenLink Request Broker

It is often best to initially start the Request Broker in (d)ebug mode, to gather the most diagnostic information -- 

# cd $OPENLINK_INSTALL
# . ./openlink.sh
# oplrqb -d
OpenLink Request Broker
Version 2.47 as of Tue Jan 08 2008 (Release 6.2 cvsid 00089).

oplrqb: using rulebook /opt/openlink/bin/oplrqb.ini
oplrqb: bound TCP protocol to 0.0.0.0.5000
oplrqb: request broker started by openlink
oplrqb: spawning /opt/openlink/bin/w3config/www_sv www_sv +debug
www_sv: started http://hostname:5000
oplrqb: started persistent www_sv (pid=25896)
oplrqb: ZeroConfig thread started
oplrqb: ZeroConfig registration Oracle 9.2 (oplussol4)

The OpenLink Request Broker will take over the terminal session, until terminated by <Ctrl-C> or other means.

Once connections are working, it is best to start without the -d or +debug arguments, to conserve disk space and minimize latency. 

# cd $OPENLINK_INSTALL
# . ./openlink.sh
# oplrqb

Testing

You are now ready to set up and test a client connection. Please proceed to the relevant client quick-start guide for the chosen operating system.

Additional Information

Any changes made to $OPENLINK_INSTALL/bin/oplrqb.ini will not take effect until the Request Broker is re-initialized. 

# cd $OPENLINK_INSTALL
# . ./openlink.sh
# oplshut +reinit


In some cases, activating settings changes require the Broker to be stopped and restarted. 

# cd $OPENLINK_INSTALL
# . ./openlink.sh
# oplshut -fy
# oplrqb


To stop a Request Broker running normally -- 

# cd $OPENLINK_INSTALL
# . ./openlink.sh
# oplshut +force
