ABOUT THIS DOCUMENT This document list steps for gathering information about a naming problem and is applicable to AIX 3.2. This document assumes that you are working with AIX Support under one of the service options. For information on the AIX Support Family and Program Services (IBM's base support for code- related problems), request these faxes from 1-800-IBM-4FAX: 1537 Overview of AIX Support 1760 Using Program Services 2464 The AIX Support Family Use the following steps to gather information about your naming problem to send to AIX Support. NOTES: _____ o Please perform all the steps given below on the machine which is having "named" problems. o Replace XXXXX with your problem number and YYY with your IBM branch office code. STEPS 1. Make a temporary subdirectory: mkdir /tmp/XXXXX 2. Make subdirectories for the primary nameserver and for each secondary. For example: mkdir /tmp/XXXXX/pri mkdir /tmp/XXXXX/sec.1 mkdir /tmp/XXXXX/sec.2 3. Copy the named configuration files on these systems to their respective directories. Among the configuration files include the "named.boot" file and each of the database files listed in named.boot. For example: Named Debug Guide 1 09/17/96, cp /etc/named.boot /tmp/XXXXX/pri cp /etc/named.data /tmp/XXXXX/pri 4. On the machine with which you are having named problems, please do the following: Start named with level 9 debugging or, if named is already running, send it "kill -USR1 " 9 times. Please note that "named" debugging will be col- lected in "/var/tmp" and that you must have sufficient space in that file system. IF you run out of space you will have to give signals to stop "named" debugging occasionally, backup the debug output, and send "named" a signal to start debug output. Examples of starting and stopping debugging are: startsrc -s named -a "-d 9" kill -USR1 `cat /etc/named.pid` 5. Now, reproduce the problem. After the problem appears, a. Send a signal to have named dump its configuration: kill -2 `cat /etc/named.pid` b. Send a signal to stop named debugging: kill -USR2 `cat /etc/named.pid` c. Issue the following commands to copy files to the temporary directory: cp /var/tmp/named.run /tmp/XXXXX cp /var/tmp/named_dump.db /tmp/XXXXX d. If a problem with zone transfer is suspected, issue the following command: cp /usr/tmp/xfr* /tmp/XXXXX e. Please include a README file in /tmp/XXXXX which includes: o Some indication of the naming hierarchy, (domains, subdomains) o Ip addresses and hostnames of all name servers, (primaries, secondaries, etc.) 6. Compress and tar the whole XXXXX directory: tar -cvf- XXXXX | compress > XXXXX.tar.Z 7. tar the compressed tar file to a diskette or tape: tar -cvf /dev/(device) XXXXX.tar.Z 8. Include on the media label the problem number and branch office number (XXXXX,YYY) and the command used to place the data on the Named Debug Guide 2 09/17/96, NOTE: Send dumps by standard mail/overnight delivery or electronically over the Internet. Within IBM, dumps can be sent over VM, but in all cases FTP is the preferred method. STANDARD MAIL OR OVERNIGHT DELIVERY All media sent in this manner must be labeled. Labeling Physical Media: To prevent delays in processing, the problem number (PMR or XMENU item number) must be on the media label. If the testcase media cannot be associated with an existing PMR or XMENU item, the files associated with these numbers will be considered lost and eventually deleted from the system. Indicate the archive format and tape block size on the media label. Sample label is: (You can determine the block size by typing: lsattr -E -l rmt# | grep block_size The block size is listed after "block_size".) VERY IMPORTANT: If the person sending this testcase is NOT the person who reported the problem, be sure to include the name of the person who reported it. If the proper informa- tion is not on the package, then process delays will occur. Approved media: 8mm tape, 4mm tape or 1/4" diskettes Mail to: NOTE: Look at the "file Naming Convention" section of this document and name testcases accordingly. IBM Corp. / Zip 2900 / Bldg 42 Attn: AIX Testcase Dept. J66S 11400 Burnet Road Austin, TX 78758-3493 Extension 3-4050 Note: NO overnight delivery service delivers directly to bldg. 42, instead they are delivered to IBM Receiving. Please keep this in mind when choosing a delivery time. If you specify Saturday delivery you must first make special arrangements with an AIX Support specialist (1-800-225-5249 Named Debug Guide 3 09/17/96, or 1-800-call-aix), otherwise there could be a delay of several days. VM (IBM INTERNAL) REMINDER: If you have absolutely no other available elec- tronic method of sending a testcase, you can send it through VNET. This method only works for IBM internal customers. It is not automated, which could cause delays in testcase proc- essing. FTP IS THE PREFERRED METHOD FOR SENDING TESTCASES. The testcase should be combined into a single compressed tar archive and uploaded in BINARY format. Please name the file PPPPPBBB TARZBIN, where PPPPP is the PMR number and BBB is the branch office number (without the "b"). node = "AUSVMR" userid = "V3DEFECT" MAILING VIA INTERNET | All users who wish to send testcases via the Internet must | read and understand the "Service Use Aggreement" below. +--- SERVICE USE AGREEMENT --------------------------------+ | | | International Business Machines Corporation | | Internet Testcase Delivery Service | | Service Use Agreement | | | | THIS IS A LEGAL AGREEMENT TO WHICH YOU ARE CONSENTING TO | | BE BOUND.

The allowable size of the testcase depends mostly on intermediate mail gateways. It is gener- ally not advisable to send tescases larger than approxi- mately 4MB via e-mail. Testcases sent via e-mail in the correct format are automatically processed, making them almost immediately available for analysis. See the "File Naming Convention" section of this document for more details. FTP Via Internet Sample file names for the tarred and compressed files: ad1000.tar.Z (item number.tar.Z) 1x234.001.tar.Z (problem_report_#.branch_office_#.tar.Z) 1x234.1234567.tar.Z (problem_report_#.customer_#.tar.Z) FTP it to our testcase repository: ftp 198.17.57.67 (or "ftp testcase.boulder.ibm.com") login: anonymous password: (e.g., "customer@wallyworld.com") bin (change to binary transfer mode) cd aix put 1x234.001.tar.Z (for example) ls -l quit Named Debug Guide 5 09/17/96, FILE NAMING CONVENTION: NOTE: Testcases should be archived into a compressed tar archive using relative path names. If FTPing, Do not create a separate directory on the testcase server. Use of the following naming convention will allow our tools to automatically move the testcase to the proper directories and update the PMR to indicate that the testcase is avail- able. Failure to use this naming convention could cause delays in processing the testcase. If the testcase files cannot be associated with an existing PMR or XMENU item, they will be tagged as lost and eventu- ally deleted. Testcases associated with PMRs ppppp.bbb.ccc.tar.Z | | | | | | | | | Indicates that the archive is compressed. | | | | If you have the gzip command available, | | | | this will be .gz rather than .Z. | | | | | | | Indicates a tar archive. | | | | | The 3 character country code. | | (May be omitted if the country code is 000.) | | | The 3 character branch office number. | The 5 character PMR number. Testcases associated with XMENU items xxxxxx.tar.Z | | | | | Indicates that archive is compressed. | | If you have the gzip command available, | | this will be .gz rather than .Z. | | | Indicates a tar archive. | The XMENU item number. CREATING A COMPRESSED TAR ARCHIVE Testcases should be archived into a compressed tar archive using relative path names. The following is an example of how to create a compressed tar archive. o Place the testcase files into a separate directory using commands similar to those in the following example. In this example, we'll use a directory named /tmp/testcase. cd /tmp mkdir testcase cp file1 file2 file3 testcase Named Debug Guide 6 09/17/96, o Execute one of the following commands to create the com- pressed tar archive. Using the gzip command (if avail- able), will generally produce a significantly smaller file. With the gzip command: tar -cf- testcase | gzip -9 >9x999.999.999.tar.gz Without the gzip command: tar -cf- testcase | compress >9x999.999.999.tar.Z Testcases should be archived into a compressed tar archive using relative path names. The following example will uuencode and send the compressed tar archive created in the previous section. You should substitute the correct filename when sending your testcase. uuencode 9x999.999.999.tar.gz 9x999.999.999.tar.gz | \ mail -s "AIX_Testcase:9x999.999.999.tar.gz" aasc@austin.ibm.com Named Debug Guide 7 09/17/96, READER'S COMMENTS Please fax this form to (512) 823-4009, attention "AIXServ Informa- tion".
