Installing DataGate/400 onto the AS/400 from the PC

Installing DataGate/400 using FTP

In order to install DataGate/400 on the AS/400 from a Save file (obtained from the Installation CD), you must have TCP/IP installed on both your PC and on the AS/400. (You must also have FTP installed on your AS/400).

Installing TCP/IP and FTP on the AS/400 is beyond the scope of this document. If you do not know whether your AS/400 has TCP/IP and/or FTP, please check with your network manager or system provider.

On the AS/400

1. Sign onto the AS/400 using an account with *SECOFR authority.

2. On the AS/400, create a library (temporary) called ASNADLVR. (Note: QTEMP must not be used).

CRTLIB ASNADLVR

3. Add this library to the library list:

ADDLIBLE ASNADLVR

4. Create a Save file in the same library as the physical file:

CRTSAVF FILE(ASNADLVR/DG8SF)

On the PC

5. To upload the Save file from the CD or PC, an FTP session must be started to the AS/400.

From Windows, click on the START button, select RUN and enter the following command:

FTP as400tcpipaddress

where as400tcpipaddress is either a TCP/IP address such as 198.176.129.35, or a machine name that is registered either in a DNS or a HOSTS file.

6. When prompted for a user name and password, enter the appropriate information that will give you privileges to upload data to the AS/400.

7. Once FTP has been started, upload the Save file to the AS/400 by entering the following commands:

a) binary

b) put x:\Datagate\FTP\ASNATEMP ASNADLVR/DG8SF

where x is the CD-ROM drive or PC disk drive

c) quit

On the AS/400

8. Restore the library called ASNATEMP from the Save file in ASNADLVR.

RSTLIB SAVLIB(ASNATEMP) DEV(*SAVF) SAVF(ASNADLVR/DG8SF)

9. To install DataGate/400, execute the following command:

ASNATEMP/LODDG8 library name

· where library name is optional. If a library name is not specified, DataGate/400 will be installed to the library DG8_40.

When DataGate/400 is installed, it is automatically authorized for one user license. If you wish to authorize more than one license to DataGate for the AS/400, obtain a code from ASNA and enter it using ASNA's Registration Assistant from Start - Programs - ASNA Product Suite on the PC.

10. Once the installation has completed, the library ASNADLVR is no longer needed, and may be deleted. (The ASNATEMP library is automatically deleted).

11. If accessing the AS/400 via TCP/IP, the DataGate server will have to be configured for TCPIP access. See Configuring TCP/IP on Windows for more information.

12. You must name the AS/400 Database in Acceler8DB Database Manager using Work with Database Names. See Naming an AS/400 Database for more information.

5. Acceptance of a valid licensing code is displayed. Select OK to clear the message, then select Exit to close Registration Assistant.

If you receive Acceler8DB error number 654 - “Not authorized to Object" after selecting the Register button, you do not have the proper authority to register DataGate/400. See Authority of the User Profile used to Register DataGate below for more information.

Back To Top

Authority of the User Profile used to Register DataGate

The user profile used to register DataGate software must have *CHANGE authority to the DG8_40 library. Additionally, it must have *ALL authority to the DGPCODE data area in DG8_40, if it already exists (say, from a previous registration of the product).

The user profile must have these authorities regardless of the method used to register the program, such as the AS/400 REGISTER command or the Windows PC Registration Assistant program.

As an example, suppose user profile ADBUSER is to be used to register DataGate. The successful execution of the following two AS/400 commands prior to registration will insure that the required object authorities will be available to ADBUSER:

GRTOBJAUT OBJ(QSYS/DG8_40) OBJTYPE(*LIB) USER(ADBUSER) AUT(*CHANGE)

GRTOBJAUT OBJ(DG8_40/DGPCODE) OBJTYPE(*DTAARA) USER(ADBUSER) AUT(*ALL)

Remember that the DGPCODE data area may not exist yet if DataGate has never been registered on the machine. If so, the second command is not necessary.

· If the Registration Assistant is used, the user profile is the "Username" specified on the Work With Database Names dialog box of Acceler8DB File Manager, and other tools.

· If the REGISTER command is used, the user profile in question is the one used to log on to the AS/400 interactive session.

ADDJOBQE SBSD(QINTER) JOBQ(xxx/DG8_SVC) MAXACT(*NOMAX) SEQNBR(13)

· where QINTER is the name of the subsystem where DataGate/400 service will run. QINTER is highly recommended, however, other subsystems may be used. The subsystem that is used for the job queries must be set up with a proper routing entry in order for DataGate service to start. This routing entry must run the program QCMD in Library QSYS and have the compare value of ‘QCMDB’ or ‘*ANY’. If the subsystem has one of these routing entries, it may be used for DataGate.

· where xxx is the name of the library where DataGate was installed in.

· where Sequence Number, if not 13, must be the first available number for the Subsystem. Enter the command WRKSBSD QINTER to determine the sequence numbers already used. Select option 6. Job queue entries. Use the next entry after the existing DataGate sequence number. Do not use the subsystem QCMN or QSERVICE.

ADDJOBQE SBSD(QINTER) JOBQ(xxx/DATAGATE) MAXACT(*NOMAX) SEQNBR(14)

· where QINTER is the name of the subsystem where DataGate/400 jobs will run. This must be the same subsystem name as in the first ADDJOBQE command above.

· where xxx is the name of the library where DataGate was installed in.

· where the Sequence Number, if not 14, must be the next available number for the Subsystem.

CHGDTAARA xxx/TCPSERVICE NewValue('Acceler8DBServiceNum2')

· where xxx is the name of the library where DataGate was installed in. It is essential that the NewValue information be entered in quotes.

ADDSRVTBLE SERVICE('Acceler8DBServiceNum2') PORT(5045) PROTOCOL('tcp') TEXT('ASNA Datagate/400 Service Table Entry #2')

It is essential that the text information be entered in quotes exactly as the NewValue information in the data area TCPSERVICE. The Protocol must also be entered in quotes.

Troubleshooting

Troubleshooting AS/400 TCP/IP Connectivity

If you are unable to connect to the AS/400 database from ASNA’s Acceler8DB Database Manager, the following information may help identify possible incorrect setups on the AS/400.

It is assumed that TCP/IP configuration has been completed correctly on the PC side. If you are unsure whether TCP/IP is installed or correctly configured on your PC, contact your network administrator for assistance.

TCP/IP names are a combination of host names (machine names) and domain names. A machine name for TCP/IP does not have to match the AS/400 machine name; however, it will be a unique name - and it can be the same as the AS/400 machine name.

Throughout this example, the machine name used is ‘machine’, and the AS/400 name is actually ‘S1037242’. The domain name used throughout this example is ‘domain.com’. Together the machine name and the domain name make a ‘complete’ TCP/IP name - ‘machine.domain.com’. At your site, you should use your own domain name and own machine name.

1. First check to see if you are able to ping the AS/400 by name from your PC. For example, if the TCP/IP name of the AS/400 is ‘machine.domain.com,’ then the following command should be issued from your machine from a DOS Box:

ping machine.domain.com

· If you do not get a ‘reply’ from the machine that was pinged, then TCP/IP may not be configured correctly, either on your machine or on the AS/400. If you receive a “Bad command or filename” error message when typing the ping command, your machine may not have TCP/IP installed. Please check with your network administrator to make sure your machine has TCP/IP capability.

· If you do get a response from the AS/400 when the ping command is issued, then it is still possible some settings on the AS/400 may be incorrect. From a command line on the AS/400, issue the following command: cfgtcp.

2. From the Configure TCP/IP menu screen that appears, select the Work with TCP/IP Interfaces (option 1).

3. The following menu screen will appear.

You should see something similar to this screen. If you do not, then TCP/IP is probably not configured on the AS/400 properly, or it may not be completely installed. Check with your AS/400 administrator to make sure the AS/400 has TCP/IP installed.

4. If there is an internet address other than 127.0.0.1 listed, select that address and enter an option 5 command to display the setting for that IP address.

· The Interface status should indicate Active. If it does not, then the TCP/IP services, although installed, may not be started, or it may have terminated. The TCP/IP services should be started.

· Try re-connecting to the AS/400 database after restarting the TCP/IP services. (To start the TCP/IP services you must have sufficient authority rights and issue the following command from a menu prompt: STRTCP). After you have done this, then issue another ping command to see if you get a reply.

5. If you reach this point and are still having problems accessing the AS/400 via TCP/IP, then F12 back to the main configuration screen for TCP/IP (Configure TCP/IP) and enter option 21 (Configure Related Tables) from the main TCP/IP configuration menu.

· On the Configure Related Tables menu screen that appears next, select option 1, Work with Service Table Entries. You will then see the Work with Service Table Entries menu screen. Scroll through the list of services to find the Acceler8DBServer entry.

· If there is no entry here, then that is the problem. Make sure you perform the installation section for the AS/400 as stated earlier in this chapter.

· If the Acceler8DBServer entry is found, then the default port will be 5042 (unless it was installed with a different port). It is strongly suggested to use Port 5042.

Note: The protocol listed in the service table entry for the ‘Acceler8DBServer’ service should be ‘tcp’. It is case sensitive, so if the letters are uppercase, you will need to remove the service and re-add the service with lower case letters.

Troubleshooting DataGate Service

If you are unable to start the DataGate Service, the following steps will assist in trouble shooting the possible causes.

When the DataGate service job is submitted for execution, the job is submitted under the user profile of DG8SVCPRF. This user profile is created during the installation and the system value for the Printer option will be assigned to this user profile. If the DataGate service job has trouble starting, a one page report outlining the possible cause of the problem will be generated for the user DG8SVCPRF and printed to the assigned printer. This report will not print unless the Output Queue associated with this printer automatically prints the generated reports. Otherwise, to view the list of reports that have not printed for this user, enter the following command:

WRKSPLF SELECT(DG8SVCPRF)

At this point you will need to contact ASNA for further assistance.

The most probable cause for the DataGate service job not starting is if the current DataGate service job is terminated with an ENDJOB command, subsequent attempts to start the service will not be successful.

1. If the DataGate service job is not currently running and it won't start by issuing the STRDG8SVR command, enter the following command:

NETSTAT

2. Select Option 3. Work with TCP/IP Connection Status.

3. Select F14 to Display Port Numbers In the Local Port column, locate the Port Number you assigned as the Port for the DataGate Service (The default Port Number is 5042).

4. You will need to end this connection by selecting Option 4.

5. When this connection is ended successfully, you may now execute the STRDG8SVR command.

Troubleshooting a DataGate Job that is Not Terminating

If you notice that a DataGate Job is still running after a client connection is lost, this is due to a TCP/IP feature called "Keep-Alive". Refer to the following to change the system's default Keep-Alive value.

When the database connection is TCP/IP, the server machine utilizes a TCP/IP feature called "Keep-Alive". Keep-Alive packets are used to probe a connection that has been inactive for a long time. The server initiates a disconnect when the probes do not get through.

This means that if the client connection is lost for a prescribed length of time, the server sends a disconnect message to its server job (usually the result of a system crash or power-down).

The default Keep-Alive setting for Windows NT and AS/400 is two hours, meaning that an Acceler8DB thread or DataGate job would remain active for 2 hours after connection was lost with the client. The 2-hour default may be an unsatisfactory period of time for you, as files would continue to remain open, etc. on an abnormal disconnection until the Keep-Alive time had elapsed.

Refer to the following to modify the server machines' respective Keep-Alive period.

AS/400

1. Request the Configure TCP/IP menu by executing the command: cfgtcp

2. Select menu item 3 - Change TCP/IP Attributes.

3. Set TCP/IP Keep-Alive to the number of minutes desired. (Note: 2 to 5 minutes should work well in most cases).

Windows NT 4.0

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk. The following was derived from Article ID Q120642.

To Change these parameters, use the following procedure:

1. Run Registry Editor (REGEDT32.EXE).

2. From the HKEY_LOCAL_MACHINE subtree, go to the following key:

\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

3. The Value is "KeepAliveTime".
If present (usually not), double click on it to edit in milliseconds as noted below. Otherwise, continue with Step 4.

4. Select "Edit -> Add Value".

5. For Value name, enter KeepAliveTime.

6. From the Data Type drop down list, select REG_DWORD.

7. Press OK.

8. In the DWORD Editor dialog, enter the number of milliseconds. Select the Radix Decimal option.

9. Select OK.

10. Enter the Keep-Alive value in milliseconds; e.g. 5 minutes = 300000 msec.

· Valid Range: 1 - 0xFFFFFFFF

· Default: 7,200,000 (two hours)

The parameter controls how often TCP attempts to verify that an idle connection is still intact by sending a Keep-Alive packet. If the remote system is still reachable and functioning, it will acknowledge the Keep-Alive transmission. Keep-Alive packets are not sent by default. This feature may be enabled on a connection by an application.

11. After typing in the value, use the "Data Type" checkbox to set the value type.

12. Select OK.

13. Exit the Registry Editor.

14. Reboot the system to make the change take effect.

Setting up a Subsystem

Basically, to set up a subsystem, you need to have a routing entry with a compare value of “QCMDB” that runs the program QCMD in QSYS.

The subsystem that is used for the job queries must be set up with a proper routing entry in order for DataGate service to start. This routing entry must run the program QCMD in Library QSYS and have the compare value of ‘QCMDB’ or ‘*ANY’. If the subsystem has one of these routing entries, it may be used for DataGate.

Troubleshooting Manually Ending Users Jobs

If DataGate is shut down and there are users connected, their jobs will still be out there and you have to manually end them. However, after manually ending the users jobs, DataGate may not start for about 5 minutes. It will start the first DG8SVC job and then end it until the 5 minutes (or so) is up.

It is likely that OS/400 is not reclaiming the DataGate TCP/IP port (5042) in a timely manner when the service and connection jobs are ended. When you "manually end" connections to DataGate, it may not have a chance to properly shut down TCP/IP resources. The system typically does not realize that those resources are no longer in use for some quantum.

The best way to avoid this is to let the connections and service end normally, though in abnormal situations this isn't always possible.

When you must use ENDJOB, etc., to end the connections and/or the service, you can sometimes use the WRKTCPSTS command to view the outstanding socket connections and end them. In such a case, if you find a socket in the "listening" state using the DataGate port, you can end this connection (but only if you are absolutely sure the service isn't running) using WRKTCPSTS. Likewise, if you find sockets connected to the DataGate port from external ports, you can end those (if you are sure that there are no jobs using the connection). The system will then reclaim the port, and a new instance of the DataGate service can use it immediately.

Finding an AS/400 IP address

If the user does not know the IP address of the AS/400 to which they are trying to Name a database, do the following. Note however, that most users should never have to do this, and you may want to "call your Network Manager” instead of performing the steps below.

1. On the PC, open a DOS window and enter:

arp -a

Note the IP addresses that appear. You will compare this list with the list generated in step 4. (Normally, there will be only one difference, and it will be the addition of the AS/400's IP address).

2. For Windows 9x: On the PC, click Start - Run the enter:

WINIPCFG

For NT/2000: At a DOS prompt, enter:

IPCONFIG

The IP address of the PC will display. Note this IP address, since you will use it in step 3.

3. On the AS/400 on a command line enter:

PING 'xxx.xxx.xxx.xxx'

where xxx.xxx.xxx.xxx is the IP addresses of the PC noted in step 2.

In the Configuration dialog, there's a drop down list box of adapters. Note that in most cases you will only have one ethernet adapter, so the only challenge is to distinguish the ethernet adapter from a dial-up adapter. This is usually easy, because dial-up adapters usually have a name like "NdisWan4".

It is also wise to NOT attempt to ping a PC that is also running 5250 emulation, etc., to the object AS/400. That's because that AS/400 will already be in the arp sorted "list", so one would not be able to know which is the target AS/400 because the list would be the same in steps 1 and 4.

4. On the PC in the DOS window, enter:

arp -a

The IP addresses are sorted. Compare the list with the list in step 1 and note the new IP address, this is the AS/400's IP address.

Upgrading OS/400 Level

If you are upgrading the OS/400 to a new level, please contact ASNA to ensure you have a compatible version of DataGate.

Note that you will also need to reconfigure DataGate for TCP/IP access (i.e., the ADDJOBQE and ADDSRVTBLE commands).

Uninstalling DataGate

If you are running multiple versions of DataGate and wish to uninstall a single version; please note the following:

DO NOT delete or rename the DG8_40 library. It is required for all versions of DataGate even though you may be installing into different library names.

For TCPIP access, you will need to remove the service table entry for the version of DataGate that you wish to uninstall. To verify the Service Table entry, display data area TCPSERVICE in the library that you are uninstalling. This data area contains the name of the Service Table entry that you will remove.

To uninstall a version of DataGate that was not installed in the default installation library DG8_40, follow the steps below.

To Uninstall DataGate

1. Remove the job queue entries for the Jobq Datagate and the Jobq DG8_SVC using the RMVJOBQE command. These Job Queues reside in the installation library. (Most commonly called DG8_40).

If you have installed DataGate into a library other than DG8_40, your job queues will reside in the library where DataGate is installed.

2. Delete the Job Queues Datagate and DG8_SVC using the DLTJOBQ command.

3. Remove Service Table Entry for TCPIP access using the following command.

RMVSRVTBLE SERVICE('Acceler8DBService') PORT(5042) PROTOCOL('tcp') TEXT('ASNA Datagate/400')

4. Delete the DataGate installation library using the DLTLIB command.

DataGate is now uninstalled.
