Apologies for the formatting of this file. I extracted the APAR list from the fixpack (it is hidden in an .INF file on disk 1, which is distributed as a diskette image) but did not bother to clean it up. - Jacco de Leeuw Note: fixpacks IP08401 and IP08402 were superceded by IP08406. After applying this FixPak, these products will be Year-2000 compliant. Note: This section describes OS/2 Version 4.0 Peer APARs that are corrected for IPx8406. IPx8406 also contains all APAR fixes included in IPx8402 and IPx8401. +------------------+ | | | INCLUDED APARS | | | +------------------+ o APAR = IC16291 AFTER INSTALL OF OS/2 WARP 4.0 WITH PEER, MANAGE ACCESS DOES NOT SHOW WHEN YOU RIGHT-CLICK ON A NETWORK DRIVE After installing OS/2 Warp 4.0 with Peer, Manage Access does not show when the user clicks on a drive that the user has Admin authority for. o APAR = IC16292 DRAG AND DROP OF FILES FROM OS/2 TO A WINDOWS 95 SYSTEM VIA A PEER CONNECTION FAILS, BUT IT WORKS FROM THE COMMAND LINE Drag and drop (copy or move) operations from the OS/2 Workplace Shell (WPS) to a network drive object for a Windows 95 resource fails (errors are shown below). However, the same operations may be performed with no problem via the command line and other programs. All that is needed for this problem to be reproduced is Peer Services and a connection to a Windows 95 peer machine with full access to a resource. After attempting a drag and drop of a file with EAs to a Windows 95 peer connection, the user will first get the dialog: Workplace Shell ! File properties (extended attributes) cannot be copied to the destination file system. Are you sure you want to copy FILENAME.EXT? Yes No Cancel Help After dismissing the prompt for action, the user will then get: Workplace Shell - C: is either read-only, or is being used by another program. OK Cancel Help The error is ERROR_ACCESS_DENIED (PMW1002). Also, extended attributes do not necessarily need to be involved. When dragging and dropping a file that has no EAs, the user will get a network message: A network error occurred. NET3196: A write operation to X:\FILENAME.EXT failed. Data may have been lost. Then after dismissing the netpopup, they will get the previous ERROR_ACCESS_DENIED. o APAR = IC16536 USING A PEERRMT-GENERATED RESPONSE FILE GIVES A SYS3175 ERROR When installing using a response file generated by PEERRMT.EXE, you get a SYS3175. o APAR = IC18687 NET DASD /TREE TRAPS WITH A SYS3175 WHEN THE RESOURCE HAS GREATER THAN 64K OF DATA When net dasd resource /tree is issued and the data returned from a netdasdenum call returns more than 64k of data, the program traps when trying to output to the screen. o APAR = IC18688 FIX FOR IC10967 IS BROKEN BY APPLICATION OF WARP FIXPAK 17 After application of OS/2 Warp FixPak XR_W017, the fix provided in APAR IC10967 no longer works. See APAR IC12353 for full recreate details. This may also happen with other levels of OS/2 Warp FixPaks. o APAR = IC18689 NEED TO CHANGE THE CODE OF THE LS GUI TO BE CONSISTENT WITH THE COMMAND-LINE INTERFACE IN LS 3.0 WHEN ASSIGNING THE "PREFERRED LOGON SERVER" If you create a new user ID by drag-and-drop from the user ID template of the GUI, the "preferred logon server" is assigned to the "Domain controller". If you create the user ID with the command-line interface, it assigns the same field to "Any". This is the way LS 3.0 did it also. LS 4.0 and Warp Server GUI's assign to DC. Most of the time, it doesn't matter. After sync. there is no real difference (DC vs. Backup DC) between the assignment to DC or "Any". But there is a need for consistency with the CLI and LS3.0. There's no such explicit assignment (no button or bullet to highlight) for the "preferred logon server" parameter done in the LS Admin GUI. It is done by the following: "The 'preferred logon server' is set/created via the logon_server field in the user_info structure. If it is set to NULL, the domain controller will be the logon server. This appears to be what we are currently setting it to in the GUI. On page 523 of the "LS 4.0 Programming Guide and Reference", there is an explanation of how to use * to set it to allow either the domain controller or the backup domain controller to be the preferred logon server. o APAR = IC18690 VNETAPI.SYS FAILS TO UPDATE CALLER'S REGISTERS DUE TO PREMATURE STI INSTRUCTION A test case has demonstrated that when the API NetUseEnum is called and the mouse is moved, the caller's registers will not be properly updated and a GPF will occur in Win-OS/2. This problem has been observed on a 9577 only. o APAR = IC18692 TRAP OCCURS IN LS209MBS.DLL WHEN DRAGGING ICON OUT OF TEMPLATES FOLDER ON THE DESKTOP OF AS/400 VERSION OF THE LS4.0 GUI 1) When the customer drags the template icon from the template folder within Client Access onto the desktop, as the customer attempts to select the Menu option on settings, it crashes Program Manager. Customer receives a SYS3175 error pointing to LS209MBS. 2) After customer views a spooled file under 132-column support, CMD3 ends the session. This problem started after installing the updated Cirrus drivers and selecting 1024 by 768 at 75HZ refresh rate. The ICON in question is part of Client Access/400 optimized for OS/2 under the TEMPLATES Folder. Drag the PC5250 template with Right mouse button onto the DESKTOP. Select 27x132 from the Notepad settings, then click on MENU from the Notepad. If the requester has been started with NET START then selecting the MENU tab in the PC5250 Notepad settings will cause the DESKTOP to shutdown and reduce all the current applications to a blank DESKTOP screen. Then it will post the MSGSYS3175 against LS209MBS.DLL. If NET START is NOT run to start the requester, then the PC5250 template can be dragged onto the desktop and a new ICON created as expected. CA/400 is 5763XG1 R311 and PC5250 is an emulator which is installed as part of the SELECTIVE Install option of CA/400. o APAR = IC18693 NET USER USERID PASSWORD /PASSWORDEXP:YES DOES NOT CHANGE PASSWORD. IT ONLY EXPIRES THE CURRENT PASSWORD. When issuing "net user userid password /passwordexp:yes" only the password is expired. The password is not changed. Expected result: Password is changed and also expired. o APAR = IC18694 ALL FIELDS IN THE HOME DIR. TAB CAN BE DUPLICATED EXCEPT "LOCAL PATH AT SERVER" ON "USER ACCT-CREATE" SCREEN OF "CREATE ANOTHER" FUNCTION APAR IC12124 fixed the duplication of all fields on the "Home Dir." tab on the "User Account - Create" screen, opened by right clicking on a user in the "User Accounts" folder, and clicking on "Create another". Warp Server IP_8260 has this same fix in it. We request that only the "Local path at server", which would include a unique user name, NOT be duplicated, and all other field designations in this tab be duplicated: "No home directory or Assigned" bullets, "Letter or Next available" drive bullets, "Server name", "CHKSTOR threshold" checked and size assigned. None of the above have been implemented in OS/2 Warp v4. o APAR = IC18695 GET NET2379 IN LSERROR.EXE IF ERROR LOG IS CLEARED Delete the error log from "LAN Server Error Log Utility", Close/Restart it, then click the error log icon again. It fails with NET2379. NET ERROR /DELETE doesn't fix the problem. CHKDSK doesn't either. o APAR = IC19148 DESKTOP PROPERTIES ARE NOT AVAILABLE AFTER APPLYING IC17587 After applying the fix for IC17587, desktop property problems are more likely to occur. o APAR = IC19508 WARP V4 LS ADMIN GUI REMOVES SERVER ID FROM SERVERS GROUP To recreate this problem on an OS/2 Warp 4.0 (GA or IP08402) workstation, do the following: Define an OS/2 LAN Server TEMPRON. 1) Find Server TEMPRON in LS Admin GUI - Connections\Network\Network Services\LS Admin Click on the Domain castle icon. Click on Defined Servers folder. The TEMPRON server icon should be visible. 2) Open the User Accounts folder. Click on the TEMPRON userid. The GROUPS tab should show USERS and SERVERS. 3) On the IDENTITY tab: Change the description. Click SET. 4) The Defined Server folder no longer shows TEMPRON. 5) The User Accounts folder continues to show TEMPRON. Clicking it shows the comment change. But GROUPS only showed USERS (SERVERS is no longer listed). 6) Command Line: NET USER TEMPRON (on the DC) Shows TEMPRON only as member of USERS. 7) Command Line: NET GROUP SERVERS no longer lists TEMPRON. The DC was continually checked while doing this, and everything was fine until SET was clicked. It appears SET makes the intended comment change but also removes TEMPRON from the group SERVERS when using the GUI on OS/2 Warp v4. +------------------+ | | | INCLUDED APARS | | | +------------------+ Note: This section describes OS/2 Version 4.0 Peer APARs that are corrected for IPx8402. o APAR = IC16787 MULTIPLE LOGON ATTEMPTS POSSIBLE The banking application IBM MERVA/2 needs users maintained by UPM for access to DB/2 and LAN Server. To achieve a single-logon concept and to re-use UPM's functions such as password control, logon panels, and password encryption, the same user entries are also used for access control to MERVA/2. The problem is that an extremely important function is missing in UPM--the detection of multiple invalid logon retries and disabling of the user. UPM has to count invalid attempts for Local AND Domain Logons as well as for NetUserValidate2 calls, reset the count for a valid logon, and disable the user when the retry limit is encountered. o APAR = IC18903 LAN AUDIT LOG HAS Y2K DATE ERROR LAN Server Error Log has Y2K date error. To recreate: Change the date on the domain controller to 1-1-2000. Start the domain controller and logon from a requester. CTRL-ALT-DEL the domain controller. At the requester, try to do a net use of a shared directory on the domain controller. Because the domain controller is still booting up, the net use will fail. This should cause an entry in the error log. The entry in the error log should show something similar to the following example: Program Date Time Message Requester 1-1-100 00:08:45 Text of error message goes here. NOTE: When the date is set to 2001 it shows as 1/1/101. o APAR = IC18905 LAN: INCORRECT TIME RANGE WHEN ADDING NEW USER While attempting to create a new user account from the command line, LAN gives an incorrect time range. The format of the command was as shown below: NET USER IT04R01U UPW04R01 /ADD /PRIV:USER /TIMES:M,11pm-12am When executing this command on dates prior to 12/31/99, the command completes successfully. On 12/31/99 or later, the command returns an error. NET3769: An incorrect time range has been supplied. o APAR = IC18962 NAMED PIPE ON SERVER SHOULD RETURN ERROR_MORE_DATA ON READ Customer created client and server applications. When the client opens and reads the pipe on a server, the return code is incorrect under the following circumstances: The server writes more data than the following client read request. The server should return ERROR_MORE_DATA but instead returns 0 as the return code. +------------------+ | | | INCLUDED APARS | | | +------------------+ Note: This section describes OS/2 Version 4.0 Peer APARs that are corrected for IPx8401. o APAR = IC15279 NET USE X: ALIAS /DOMAIN:DOMNAME DOES NOT WORK AS ADVERTISED IN HELP UNDER OS/2 WARP V4. GET NET2783 OR NET2795 ERRORS. Although the NET USE X: ALIAS allows the /DOMAIN switch and the NET HELP USE info says this is a valid option, the option does not work under the peer requester for OS/2 Warp v4. You typically will get a NET2783 message indicating that the alias does not exist if you try. o APAR = IC15858 IF THE PATH STATEMENT IN THE CONFIG.SYS HAS MORE THAN 520 CHARACTERS, PEERINST.EXE WILL TRAP WITH A SYS3175 If the path statement in the config.sys has more than 520 charcaters PEERINST.EXE will trap. The error is SYS3175. o APAR = IC15963 SHARED RESOURCES AND NETWORK CONNECTIONS GUI DISPLAYS SYS0234 ON CONNECTIONS PAGE WHEN MORE THAN 4K OF DATA IS RETURNED Shared Resources and Network Connections GUI displays sys0234 on connections page when connected to a server that has more than 4K of data returned on the NetShareEnum call. Click on Shared Resources Click on Connections page Click on create connection Click on a server that has numerous shares on it (>4K of data) Error pops up sys0234: More data is available. o APAR = IC16090 WARP V4 CLIENT WITH LS GUI: WHEN CHANGING THE "PASSWORD EXPIRES DAYS" ON THE PROPERTIES, THE POLICY PAGE RETURNS NET2123 ERROR POPUP From a Warp V4 client using the LS GUI and trying to administer LS4.0 server by trying to change the PASSWORD EXPIRES to "after xxx days" from the POLICY page of the domains properties page and click on the "SET" button the user receives popup error window: NET2123: The Api return buffer is too small. The exact steps to reproduce are below: - open the admin gui (start netgui) - open the PROPERTIES of a domain object - goto page POLICY - change the PASSWORD EXPIRES from NEVER to AFTER 30 days (or if you already have selected AFTER 30 days, make it 31; just to have a change) - select the SET pushbutton - the NET2123 error (Api return buffer too small) window pops up If you try to close the PROPERTIES window by any other way than the "CANCEL" button, you will receive the same error popup. o APAR = IC17238 USING OS/2 V4 GUI WITH LAN SERVER SOFTWARE, USER FINDS NO OPEN FILES GOING TO AN ADVANCED WARP SERVER, 386HPFS DC Using OS/2 v4 GUI with LAN Server software, users finds no "open files" going to an advanced Warp server, 386HPFS DC. However, when the customer goes through OS/2 Warp Connect with LS 5.0, the customer can see the open files. The filenames are < 8 bytes with no special or reserved names. Open files appear on additional server but not on the DC. To recreate: Start the network and click on the Domain icon, then the Defined Servers icon, and then Domain Controller. Under this is an option "Open as.." and one of these selections is to show the "open files". When you click on this "open files" under OS/2 Warp v4, nothing is displayed in the open files list. If the same is done under Warp Connect, it displays open files with no problem. The number of open files listed by an OS/2 Warp v3 system is 50, and under the same environment OS/2 Warp v4 does not show even one as open. o APAR = IC17297 DURING THE BOOT PROCESS OF OS/2 WARP 4.0, USER ENCOUNTERS A "SYS0039: THE X: DEVICE IS NOT READY", WHERE X: IS THE CD-ROM During the boot process of OS/2 Warp 4.0, user encounters a "SYS0039: The x: device is not ready", where x: is the CD-ROM drive. This error will be encountered just after the WPS paints the background bitmap of the Desktop (assuming one exists) and just before one would expect the WarpCenter and the Desktop to start to come up. The error looks something like the following: System Error - Desktop SYS0039 The X: device is not ready. Options o Return error code to program o Retry command or operation This occurs when the requester is started. o APAR = IC17497 WHEN RUNNING A DOS APP (THAT USES FCBS) IN 2 SESSIONS ON A LAN REQUESTER TO A ENTRY SERVER, THE CUSTOMER GETS FILE ERRORS WHEN ENDING. Running multiple sessions of a DOS APP called PMS from his Warp Server Entry Domain controller. There is only the Warp Server DC and a Warp Connect client, with FP 17 applied in this environment. The application will run if only one session is running. If more than one session is running, upon closing the second session, a NET3196 error is displayed. o APAR = IC17498 USING DOSCOPY FUNCTION TO COPY A FILE ON A SHARED DRIVE TO A SHARED PRINTER FROM SAME SERVER FAILS WITH RC=50 Customer wrote a program that uses doscopy function to send files to print. It works fine unless the file is from a shared drive that is on the same server as the shared printer it was sent to. It fails with a return code of 50. o APAR = IC17499 TRAP IN NETWKSTA.200 FREECONN + 1D Trap in Netwksta. This seems similar to IC12000 but different. 1ea8:000045d3 NETWKSTA FreeCONN + 1 o APAR = IC17500 LOGOFF APPEARS TO HANG UNTIL ONE OF THE MANY APPLICATIONS ARE STOPPED On a server with LAN Server, DB/2, COMMGR and many other apps running, when a logoff is attempted the session running the logoff appears hung. Ending one or more of the apps will free the session to complete. o APAR = IC17501 A COMMAND LINE LOCAL LOGON FOLLOWING A GUI DOMAIN LOGON AND LOGOFF WILL CAUSE NETWORK TRAFFIC TO THE DC To recreate this problem, do the following: 1. Do a command-line local logon 'logon userid /p:password /l' 2. Type 'logon' and do a domain logon through the logon GUI 3. Logoff 4. Do another command-line local logon as in step one. This is causing problems where auditing is used. Local logons are triggering the auditing, which should not occur. o APAR = IC17502 NETWORK MESSAGING IN W.S. REQ. 5.0 LOOKS FOR "GROUPS" USER IDS. IN THE LOCAL NET.ACC AND NOT IN THE D.C.'S NET.ACC Network messaging of Warp Server requester 5.0 will look to the locaL net.acc instead of the D.C. or server's net.acc when clicking on "Groups" for the user id's of a group. The error returned states that there are no groups found. o APAR = IC17503 WHEN RUNNING A DOS APP (THAT USES FCBS) IN 2 SESSIONS ON A LAN REQUESTER TO A ENTRY SERVER, GETS FILE ERRORS WHEN ENDING Running multiple sessions of a DOS APP called PMS from his Warp Server Entry Domain controller. There is only the Warp Server DC and a Warp Connect client, with FP 17 applied in this environment. The application will run if only one session is running. If more than one session is running, upon closing the second session, a NET3196 error is displayed. o APAR = IC17504 EXPORTING CONFIGURATION MAPS FROM TWO VISUAL AGE CLIENTS TO THE SAME FILE ON LS WILL CAUSE INVALID DATA ERROR FOR ONE CLIENT Exporting name configuration maps from two clients to the same file on Lan Server will cause one of the clients to receive an error about the data being invalid. The other client will complete without problems. o APAR = IC17505 LS 5.0 PEER SERVICE, UPMEULGN API FAILS WHEN /V:NONE IS USED When running LS 5.0 peer service, the UPMEULGN api will fail when /V:NONE is used. Error msg: logon verification none is not allowed when the server services are started. o APAR = IC17506 SYSTEM HANGS DUE TO PROBLEM USING SHORT TERM LOCKS During testing, customer's system hangs. Deadlock occurs when two sessions are doing DosLoadModules, DosQAppTypes, etc. o APAR = IC17507 A SYS3175 TRAP IN MSRV.EXE ON NETWORK MESSAGING SESSION. AN ACCESS VIOLATION AT 000127BB 0001:000027BB ON MULTIPLE-CARD SERVER SYS3175 trap in MSRV.EXE on Network Messaging session. A program generated an access violation at 000127bb. o APAR = IC17508 NET2454 DURING LOGON, DOMAIN CONTROLLER ERROR LOG SHOWS NET3225. During heavy logon load, users receive NET2454 (logon information could not be set) and server net error shows NET3225 (error updating logon/logoff information for user). Once this starts, netlogon service on the domain controller must be stopped and restarted for users to logon. This only happens when a very large number of users (1600) have logged on and many more are logging on. o APAR = IC17519 NET USER USERID DISPLAYS TIME INCORRECTLY ON THE PASSWORD LAST SET AND PASSWORD CHANGEABLE FIELDS After IC14802 is installed, the password last set and password changeable times display the current time. o APAR = IC17520 ENTRY SERVER RETURNS WRONG ERROR CODE FOR A NON-EXISTENT FILE When attached to an entry server network drive with a non-admin user, openandx returns errclass 2 errcode 4 to a file like x:\xfax.exe\2. x:\xfax.exe does exist. o APAR = IC17525 NET USER USERID COMMAND AFTER NET USER USERID /PASSWORDEXP:YES STILL DISPLAYS NEVER IN THE PASSWORD EXPIRED FIELD After issuing a net user userid /passwordexp:yes to expire a users password, the display from the cli says the password never expires. The date the password was last changed is the current time and the date of the password changeable field is set to the current time also. The users password has expired, so that when the user tries to logon, they will get an expired password message. o APAR = IC17526 TRAP IN SERVER DISPATCH CAUSED BY BAD POINTER TO NCB STRUCTURE The code was pointing to a bad place in memory for an ncb structure. o APAR = IC17527 / IC17528 INCORRECT OUTPUT FROM NET ACCESS /TREE COMMAND IF RESOURCES ARE SIMILAR, SUCH AS PUBLIC, PUBLIC1, PUBLIC2 The net access public /tree command gives incorrect output for this resource if there are also other resources beginning with the same characters (public1, public2). The output is mixed between the the 1st resource and the other resources. The command should only show the acp's with associated permissions for the specified resource and all its subdirectories. o APAR = IC17529 SYS3175 WHEN RESTORING ACL'S WITH RESTACC D:\*.* TO AN HPFS DRIVE. When restoring ACL's to an hpfs drive with restacc d:\*.* d:\file /s/v, gives SYS3175 access violation at 0001027d. This does not fail to a fat drive. o APAR = IC17530 OS/2 WARP V4 PEER OVER WARP CONNECT PEER CAUSES A SYS3175 ERROR When installing OS/2 Warp v4 Peer over Warp Connect Peer causes a SYS3175 trap. 1) Install Warp Connect with peer 2) Install OS/2 Warp v4 with peer 3) On the Configuration panel deselect the 3 check boxes at the lower right a) Install LAN Server Administration (uncheck) b) Install sharing (uncheck) c) Delete user ID database (uncheck) SYS3175 A program generated an access violation at 1f9addb6. SOM.DLL 0001:0000ddb6 EBP=00d57c2c FLG=00012212 o APAR = IC17531 VIEWING MORE THAN 200 FILES IN A DIR. THROUGH FILE OPEN IN E.EXE FROM A NETWORK DRIVE SHOWS ONLY 120-140 FILES. When viewing more than 200 files in a directory through file open in e.exe from a network or redirected drive, only 120-140 files are visible. The problem is not present through the drives folder or when viewing a network drive from a command prompt. o APAR = IC17532 NET DASD ON DLS REQUESTER SHOWS INCORRECT AVAILABLE SPACE A net dasd command on a DLS requester shows a limit of 1200kb size of 1197kb and available space of 4kb. A net dasd on an OS/2 requester on the same resource shows available space of 3kb, which is correct. The DLS net dasd command is showing the incorrect amount of available space. o APAR = IC17533 FIXACC CORRUPTS SERIAL VALUES IN THE USER HASH TABLE After running fixacc.exe on a server the serial values in the hash table are unusually large (i.e. 3225843969). o APAR = IC17534 WKSTA.EXE CAUSING SYS3175 WHEN PARSING A MAILSLOT TRANSACTION SMB Wksta is trapping while processing a SMB Mailslot Transaction announce. o APAR = IC17535 WARP CONNECT PEER SERVICE, UPMEULGN API FAILS WHEN /V:NONE IS USED When running Warp Connect OS/2 Peer, the UPMEULGN api will fail when /V:NONE is used. Error msg: logon verification none is not allowed when the server services are started. o APAR = IC17536 DCDBREPL LOGGING NET3196 06 00 ERRORS IN THE AUDIT LOG During DCDB replication the BDC will log: NET3228: The following error occurred while updating the access control profile for C:\IBMLAN\DCDB\USERS\ 06 00 Replication completes sucessfully and there are no problems with the user directories. o APAR = IC17537 OPEN PUBLIC APPS FOLDER DROPS LOGON ASSIGNMENTS FOR DRIVES THAT ARE ALSO USED BY PUBLIC APP. User USER1 has logon assignments of R:, S: and T: and two public apps with one of them using a network drive T:. After logon, a net use shows the three drives and the public apps folder. If the folder is opened and then a net use done, the T:. drive is no longer there. o APAR = IC17538 NETWORK APPLICATIONS FOLDER WILL NOT SHOW APPLICATIONS IF WORKING DIRECTORY IS DEFINED AS ON REQUESTER AFTER IP08222 Network (Public) applications folder is not populated by any applications that have a working directory defined as being LOCAL to the requester (the local drive can be physically located on the client or a network drive, the failure is the same). o APAR = IC17539 INTERMITTENT RETURN CODE OF FF IN THE COMMAND COMPLETE FIELD OF THE NCB AFTER COMPLETION Intermittent return code of FF in the command complete field of the NCB after completion. Lotus coded a workaround in NOTES. The workaround caused them to check the field twice if they saw the FF in the completion field. This usually works, but occasionally it does not clear after subsequent passes. When this occurs, the workaround ceases to correct the problem. o APAR = IC17540 IF WRKHEURISTICS BIT 38 IS GREATER THAN 1, IT WILL NOT BE RECOGNIZED BY PEER INSTALL AND WILL CAUSE AN ERROR The peer install program ends with an error when Wrkheuristics 38 is made greater then 1. This bit was changed to have a max value of 3 because of APAR IC12765. To recreate this problem, the user changes bit 38 in the IBMLAN.INI to 2 or 3 and saves the file. Next, the user runs the peer install program (PEERINST) and the program will exit with an error. LOCAL FIX: A workaround for this problem if the file IBMLAN.VAL exists on the local machine is to change Parm39 max=1 to max=3. The value is in the Requester section. Under the Requester section find keyword = wrkheuristic and under this is Parm39 = Min = 0 Max = 1.
