• Repair ext4 filesystem on USB drive

  - by phineas

  Yet another filesystem question. I wanted to use a USB drive that I hadn't mounted for a month or so and was surprised by the fact Ubuntu was unable to mount it. I looked it up in the disk utility and it said it discovered a device with 17 MB instead of 2 GB. The hardware looks intact, I hope for the best for repairing the ext4 filesystem. I followed the instructions from HOWTO: Repair a broken Ext4 Superblock in Ubuntu, but I wasn't successful. # fsck.ext4 -v /dev/sdb e2fsck 1.42.5 (29-Jul-2012) ext2fs_open2: Bad magic number in super-block fsck.ext4: Superblock invalid, trying backup blocks... fsck.ext4: Bad magic number in super-block while trying to open /dev/sdb The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 Filesystem blocks are invalid, however when I run the recommended solution to try the alternate superblock, I get the following output: # e2fsck -b 8193 /dev/sdb e2fsck 1.42.5 (29-Jul-2012) e2fsck: Invalid argument while trying to open /dev/sdb plus the same error message as in the last paragraph above. Any ideas how to recover the drive? Thank you very much! Edit: testdisk won't help. I'm still stunned why the tools only discover 17 MB.

• Server 2003 SP2 BSOD caused by fltmgr.sys

  - by MasterMax1313

  I'm running into a problem where a Server 2003 SP2 box has started crashing roughly once an hour, BSODing out with the message that fltmgr.sys is probably the cause. I ran dumpchk.exe on the memory.dmp file, indicating the same thing. Any thoughts on typical root causes? The following is the error code I'm seeing: Error code 0000007e, parameter1 c0000005, parameter2 f723e087, parameter3 f78cea8c, parameter4 f78ce788. After running dumpchk on the memory.dmp file, I get the following note: Probably caused by : fltmgr.sys ( fltmgr!FltGetIrpName+63f ) The full log is here: Microsoft (R) Windows Debugger Version 6.12.0002.633 X86 Copyright (c) Microsoft Corporation.

• apache syslog-ng error logs and access logs

  - by uzumaki naruto

  I am trying to send all my apache logs to syslog-ng(on remote machine) which in turn writes to a file. so I configure syslog-ng this way source s_apache { unix-stream("/var/log/apache_log.socket" max-connections(512) keep-alive(yes)); }; filter f_apache { match("error"); }; destination df_custom { file("/var/log/custom.log"); }; log { source(s_apache); filter(f_apache); destination(df_custom); }; and add the following line to apache2.conf ErrorLog "|/usr/bin/logger -t 'apache' -u /var/log/apache_log.socket" but only logs being written to "/var/log/custom.log" are [Mon Jul 13 17:24:36 2009] [notice] caught SIGTERM, shutting down and [Mon Jul 13 17:26:11 2009] [notice] Apache/2.2.11 (Ubuntu) configured -- resuming normal operations I want all logs to be sent to custom.log..... Please help me.... where am I going wrong?

• Regex for date.

  - by Harikrishna

  What should be the regex for matching date of any format like 26FEB2009 30 Jul 2009 27 Mar 2008 29/05/2008 27 Aug 2009 What should be the regular expression for that ? I have regex that matches with 26-Feb-2009 and 26 FEB 2009 with but not with 26FEB2009. So if any one know then please update it.

  Hi, I'm having some trouble using regular expression to get date in a string. Example : string text = "75000+ Sept.-Oct. 2004"; MatchCollection dates = Regex.Matches(text, @"[0-9]{5,}[+][\s](jan|feb|fev|mar|apr|avr|may|mai|jun|jui|jul|jui|aug|aoû|sept|oct|nov|dec)[\.][\-](jan|feb|fev|mar|apr|avr|may|mai|jun|jui|jul|jui|aug|aoû|sept|oct|nov|dec)[\.]\s[0-9]{4}", RegexOptions.IgnoreCase); This code is matching with my current string but i would like to get in my matchcollection, "Sept 2004" and "Oct 2004" in order to parse it in 2 datetime. If anyone have any idea, thanks a lot.

• SQL - suppressing duplicate *adjacent* records

  - by Trevel

  I need to run a Select statement (DB2 SQL) that does not pull adjacent row duplicates based on a certain field. In specific, I am trying to find out when data changes, which is made difficult because it might change back to its original value. That is to say, I have a table that vaguely resembles: A, 5, Jan A, 12, Feb A, 12, Mar A, 12, Apr A, 9, May A, 9, Jun A, 5, Jul And I want to get the results: A, 5, Jan A, 12, Feb A, 9, May A, 5, Jul discarding adjacent duplicates but keeping the last row. The obvious: Select Letter, Number, Min(Month) from Table group by Letter, Number does not work -- it doesn't include the last row.

• Why doesn't my Perl script start under FastCGI?

  I am getting this error in error_log one of my Perl CGI application. I am pretty sure I haven't changed my script at all and all of a sudden i have started getting this error. This is what I see in error_log: [Wed Jul 8 15:18:20 2009] [warn] FastCGI: server "/local/web/test/cgi-bin/test.pl" (pid 17033) terminated by calling exit with status '255' [Wed Jul 8 15:18:20 2009] [warn] FastCGI: server "/local/web/test/cgi-bin/test.pl" has failed to remain running for 30 seconds given 3 attempts, its restart interval has been backed off to 600 seconds (The snippet was edited for clarity) Also, the AddHandler line for FastCGI exists in the config file. Can any tell me the possible reasons for this error? There is nothing recorded in Apache logs.

  I am trying to remove a trailing - (dash) at the end of the string. Here is my code: <?php $str = 'SAVE $45! - Wed. Beach Co-ed 6s (Jul-Aug)'; echo ereg_replace('([^a-z0-9]+)','-',strtolower($str)); ?> produces this: save-45-wed-beach-co-ed-6s-jul-aug- How can I remove a specific trailing character only if its there, in this case the dash?

• NetBackup with VSS and Instant Recovery - Failing to delete old snapshots

  - by Jonathan Bourke

  We are attempting to implement Microsoft VSS for snap-shotting in our NetBackup 6.5.3.1 environment. The clients are both 32 & 64 bit Windows 2003 Server. Snapshot parameters are: Instant recovery is enabled Maximum snapshots = 1 Provider type = 1 (System) Snapshot attribute = 1 (Differential) All backups successfully complete, and VSS shadows are successfully created both for the snapshot backup and for the open files (shadow copy components). The Issue: NetBackup is not clearing or overwriting old snapshots with each successive backup. When we list shadows, and shadow storage, it is increasing and increasing. IT is not honouring the Maximum Snapshot setting. The Logs: The bpfis log doesn’t really appear to show any errors other than for methods which we are not employing (VxVM, Flashsnap, etc.).

• svnstat script

  - by Kyle Hodgson

  So I'm building out a shell script to check out all of our relevant svn repositories for analysis in svnstat. I've gotten all of this to work manually, now I'm writing up a bash script in cygwin on my Vista laptop, as I intend to move this to a Linux server at some point. Edit: I gave up on this and wrote a simple .bat script. I'll figure out the Linux deployment some other way. Edit: added the sleep 30 and svn log commands. I can tell now, with the svn log command, that it's not getting to the svn log ... this time, it did Applications, and ran the log, and then check out Database, and froze. I'll put the sleep 30 before and after the log this time. co2.sh #!/bin/bash function checkout { mkdir $1 svn checkout svn://dev-server/$1 $1 svn log --verbose --xml >> svn.log $1 sleep 30 } cd /cygdrive/c/Users/My\ User/Documents/Repos/wc checkout Applications checkout Database checkout WebServer/www.mysite.com checkout WebServer/anotherhost.mysite.com checkout WebServer/AnotherApp checkout WebServer/thirdhost.mysite.com checkout WebServer/fourthhost.mysite.com checkout WebServer/WebServices It works, for the most part - but for some reason it has a tendency to stop working after a few repositories, usually right after finishing a repository before going to the next one. When it fails, it will not recover on its own. I've tried commenting out the svn line, it goes in and creates all the directories just fine when I do that - so its not that. I'm looking for direction as well as direct advice. Cygwin has been very stable for me, but I did start using the native rxvt instead of "bash in a cmd.exe window" recently. I don't think that's the problem, as I've left top on remote systems running all night and rxvt didn't seem to mind. Also I haven't done any bash scripting in cygwin so I suppose this might not be recommended; though I can't see why not. I don't want all of WebServer, hence me only checking out certain folders like that. What I suspect is that something is hanging up the svn checkout. Any ideas here? Edit: this time when I hit ctrl+z to cancel out, I forgot I was on Windows and typed ps to see if the job was still running; and as you can see there are lots of svn processes hanging around... strange.

• After each command tmux prints: ps1_update: command not found

  On Linux Ubuntu 11.04, after each command (cd, ls, vim...) successful or not, tmux prints out as a last line ps1_update: command not found. Is there any config option I am missing? Thank you very much! tmux.conf # http://lukaszwrobel.pl/blog/tmux-tutorial-split-terminal-windows-easily # just remember that after every modification, tmux must be refreshed # to take new settings into account. # This can be achieved either by restarting it or by typing in: # tmux source-file .tmux.conf # Here is a list of a few basic tmux commands: # Ctrl+b " - split pane horizontally. # Ctrl+b % - split pane vertically. # Ctrl+b arrow key - switch pane. # Hold Ctrl+b, don't release it and hold one of the arrow keys - resize pane. # !Ctrl+b c - (c)reate a new window. # !Ctrl+b n - move to the (n)ext window. # Ctrl+b p - move to the (p)revious window. # Shift+LMB - select text. # ALT+Arrows to move among panes. # rebind default prefix to C-a unbind C-b set -g prefix C-a # use ALT+Arrows to move around panes bind -n M-Left select-pane -L bind -n M-Right select-pane -R bind -n M-Up select-pane -U bind -n M-Down select-pane -D # activity monitoring setw -g monitor-activity on set -g visual-activity on # highlight current pane set-window-option -g window-status-current-bg yellow # enable pane switching with mouse set-option -g mouse-select-pane on # read bashrc source ~/.bashrc # Sane scrolling set -g terminal-overrides 'xterm*:smcup@:rmcup@' commandline print out ($(cat)user@tiki:~/.vim$ ls autoload bash_profile bashrc bundle README.md tmux.conf vimrc xmonad xmonad-ubuntu-conf xsessionrc ps1_update: command not found ($(cat)user@tiki:~/.vim$ ll total 56 drwxrwxr-x 2 user user 4096 Mar 17 10:20 autoload/ -rw-rw-r-- 1 user user 170 Mar 17 10:20 bash_profile -rw-rw-r-- 1 user user 4004 Apr 2 11:37 bashrc drwxrwxr-x 20 user user 4096 Aug 20 10:55 bundle/ -rw-rw-r-- 1 user user 11170 Aug 20 11:24 README.md -rw-rw-r-- 1 user user 1243 Mar 17 10:20 tmux.conf ps1_update: command not found ($(cat)user@tiki:~/.vim$ And the following is plain terminal output, without tmux running user@tiki:~$ ls backup_list.md Documents Dropbox examples.desktop hakers_and_painters.md~ hyundai Music projects ror Ubuntu One Videos windows.sh Desktop Downloads elif.txt hakers_and_painters.md help.txt maqola.txt Pictures Public tmp update_background.sh VirtualBox VMs user@tiki:~$ ll total 116 -rw-rw-r-- 1 user user 380 Aug 9 17:34 backup_list.md drwxr-xr-x 6 user user 4096 Jul 15 09:26 Desktop/ drwxr-xr-x 2 user user 4096 Jul 7 11:26 Documents/ drwxr-xr-x 11 user user 20480 Aug 20 13:53 Downloads/ -rwx------ 1 user user 729 May 7 14:45 update_background.sh* drwxr-xr-x 2 user user 4096 Dec 10 2013 Videos/ drwxrwxr-x 4 user user 4096 Sep 10 2013 VirtualBox VMs/ -rwxrwxr-x 1 user user 36 Jan 11 2014 windows.sh* user@tiki:~$ cd Desktop/ user@tiki:~/Desktop$ ll total 36 -rw-rw-r-- 1 user user 3388 Jul 14 17:10 daily--report.md -rw-rw-r-- 1 user user 71 Jan 28 2014 fernandez readme.md -rw-rw-r-- 1 user user 23 Jan 28 2014 fernandez readme.md~ drwx------ 4 user user 4096 Mar 23 14:02 my_docs/ drwx------ 2 user user 4096 Feb 3 2014 Origami/ drwx------ 7 user user 4096 Feb 1 2013 Plants_vs._Zombies_v1.2.0.1065/ -rwxr-xr-x 1 user user 301 Apr 15 11:28 Sky Fight.desktop* drwx------ 2 user user 4096 Feb 11 2014 webdesign/ -rwxrwxr-x 1 user user 26 Jan 11 2014 windows.sh~* user@tiki:~/Desktop$

• It’s time that you ought to know what you don’t know

  - by fatherjack

  There is a famous quote about unknown unknowns and known knowns and so on but I’ll let you review that if you are interested. What I am worried about is that there are things going on in your environment that you ought to know about, indeed you have asked to be told about but you are not getting the information. When you schedule a SQL Agent job you can set it to send an email to an inbox monitored by someone who needs to know and indeed can do something about it. However, what happens if the email process isnt successful? Check your servers with this: USE [msdb] GO /* This code selects the top 10 most recent SQLAgent jobs that failed to complete successfully and where the email notification failed too. Jonathan Allen Jul 2012 */ DECLARE @Date DATETIME SELECT @Date = DATEADD(d, DATEDIFF(d, '19000101', GETDATE()) - 1, '19000101') SELECT TOP 10 [s].[name] , [sjh].[step_name] , [sjh].[sql_message_id] , [sjh].[sql_severity] , [sjh].[message] , [sjh].[run_date] , [sjh].[run_time] , [sjh].[run_duration] , [sjh].[operator_id_emailed] , [sjh].[operator_id_netsent] , [sjh].[operator_id_paged] , [sjh].[retries_attempted] FROM [dbo].[sysjobhistory] AS sjh INNER JOIN [dbo].[sysjobs] AS s ON [sjh].[job_id] = [s].[job_id] WHERE EXISTS ( SELECT * FROM [dbo].[sysjobs] AS s INNER JOIN [dbo].[sysjobhistory] AS s2 ON [s].[job_id] = [s2].[job_id] WHERE [sjh].[job_id] = [s2].[job_id] AND [s2].[message] LIKE '%failed to notify%' AND CONVERT(DATETIME, CONVERT(VARCHAR(15), [s2].[run_date])) >= @date AND [s2].[run_status] = 0 ) AND sjh.[run_status] = 0 AND sjh.[step_id] != 0 AND CONVERT(DATETIME, CONVERT(VARCHAR(15), [run_date])) >= @date ORDER BY [sjh].[run_date] DESC , [sjh].[run_time] DESC go USE [msdb] go /* This code summarises details of SQLAgent jobs that failed to complete successfully and where the email notification failed too. Jonathan Allen Jul 2012 */ DECLARE @Date DATETIME SELECT @Date = DATEADD(d, DATEDIFF(d, '19000101', GETDATE()) - 1, '19000101') SELECT [s].name , [s2].[step_id] , CONVERT(DATETIME, CONVERT(VARCHAR(15), [s2].[run_date])) AS [rundate] , COUNT(*) AS [execution count] FROM [dbo].[sysjobs] AS s INNER JOIN [dbo].[sysjobhistory] AS s2 ON [s].[job_id] = [s2].[job_id] WHERE [s2].[message] LIKE '%failed to notify%' AND CONVERT(DATETIME, CONVERT(VARCHAR(15), [s2].[run_date])) >= @date AND [s2].[run_status] = 0 GROUP BY name , [s2].[step_id] , [s2].[run_date] ORDER BY [s2].[run_dateDESC] These two result sets will show if there are any SQL Agent jobs that have run on your servers that failed and failed to successfully email about the failure. I hope it’s of use to you. Disclaimer – Jonathan is a Friend of Red Gate and as such, whenever they are discussed, will have a generally positive disposition towards Red Gate tools.

• Why won't fetchmail work all of a sudden?

  - by SirCharlo

  I ran a chmod 777 * on my home folder. (I know, I know. I'll never do it again.) Ever since then, fetchmail seems to be broken. I use it to fetch mail from an Exchange 2003 mailbox through DAVMail and OWA. The problem is that fetchmail complains about an "expunge mismatch" whenever I get a new message. It deletes the message from the Exchange mailbox, yet it never forwards it. There seems to be a problem somwhere along the mail processing, but I haven't been able to pinpoint where. Any help would be appreciated. Here are the relevant config files. ~/fetchmailrc: set no bouncemail defaults: antispam -1 batchlimit 100 poll localhost with protocol imap and port 1143 user domain\\user password Password is root no rewrite mda "/usr/bin/procmail -f %F -d %T"; ~/procmailrc: :0 * ^Subject.*ack | expand | sed -e 's/[ ]*$//g' | sed -e 's/^/ /' > /usr/local/nagios/libexec/mail_acknowledgement ~/.forward: | "/usr/bin/procmail" And here is the output when I run fetchmail -f /root/.fetchmailrc -vv: fetchmail: WARNING: Running as root is discouraged.

• Oracle Magazine - Deriving and Sharing Business Intelligence Metadata

  - by David Allan

  There is a new Oracle Magazine article titled 'Deriving and Sharing Business Intelligence Metadata' from Oracle ACE director Mark Rittman in the July/August 2010 issue that illustrates the business definitions derived and shared across OWB 11gR2 and OBIEE: http://www.oracle.com/technology/oramag/oracle/10-jul/o40bi.html Thanks to Mark for the time producing this. As for OWB would be have been useful to have had the reverse engineering capabilities from OBIEE, interesting to have had code template based support for deployment of such business definitions and powerful to use these objects (logical folders etc.) in the mapping itself.

• Oracle Database 12 c New Partition Maintenance Features by Gwen Lazenby

  - by hamsun

  One of my favourite new features in Oracle Database 12c is the ability to perform partition maintenance operations on multiple partitions. This means we can now add, drop, truncate and merge multiple partitions in one operation, and can split a single partition into more than two partitions also in just one command. This would certainly have made my life slightly easier had it been available when I administered a data warehouse at Oracle 9i. To demonstrate this new functionality and syntax, I am going to create two tables, ORDERS and ORDERS_ITEMS which have a parent-child relationship. ORDERS is to be partitioned using range partitioning on the ORDER_DATE column, and ORDER_ITEMS is going to partitioned using reference partitioning and its foreign key relationship with the ORDERS table. This form of partitioning was a new feature in 11g and means that any partition maintenance operations performed on the ORDERS table will also take place on the ORDER_ITEMS table as well. First create the ORDERS table - SQL CREATE TABLE orders ( order_id NUMBER(12), order_date TIMESTAMP, order_mode VARCHAR2(8), customer_id NUMBER(6), order_status NUMBER(2), order_total NUMBER(8,2), sales_rep_id NUMBER(6), promotion_id NUMBER(6), CONSTRAINT orders_pk PRIMARY KEY(order_id) ) PARTITION BY RANGE(order_date) (PARTITION Q1_2007 VALUES LESS THAN (TO_DATE('01-APR-2007','DD-MON-YYYY')), PARTITION Q2_2007 VALUES LESS THAN (TO_DATE('01-JUL-2007','DD-MON-YYYY')), PARTITION Q3_2007 VALUES LESS THAN (TO_DATE('01-OCT-2007','DD-MON-YYYY')), PARTITION Q4_2007 VALUES LESS THAN (TO_DATE('01-JAN-2008','DD-MON-YYYY')) ); Table created. Now the ORDER_ITEMS table SQL CREATE TABLE order_items ( order_id NUMBER(12) NOT NULL, line_item_id NUMBER(3) NOT NULL, product_id NUMBER(6) NOT NULL, unit_price NUMBER(8,2), quantity NUMBER(8), CONSTRAINT order_items_fk FOREIGN KEY(order_id) REFERENCES orders(order_id) on delete cascade) PARTITION BY REFERENCE(order_items_fk) tablespace example; Table created. Now look at DBA_TAB_PARTITIONS to get details of what partitions we have in the two tables – SQL select table_name,partition_name, partition_position position, high_value from dba_tab_partitions where table_owner='SH' and table_name like 'ORDER_%' order by partition_position, table_name; TABLE_NAME PARTITION_NAME POSITION HIGH_VALUE -------------- --------------- -------- ------------------------- ORDERS Q1_2007 1 TIMESTAMP' 2007-04-01 00:00:00' ORDER_ITEMS Q1_2007 1 ORDERS Q2_2007 2 TIMESTAMP' 2007-07-01 00:00:00' ORDER_ITEMS Q2_2007 2 ORDERS Q3_2007 3 TIMESTAMP' 2007-10-01 00:00:00' ORDER_ITEMS Q3_2007 3 ORDERS Q4_2007 4 TIMESTAMP' 2008-01-01 00:00:00' ORDER_ITEMS Q4_2007 4 Just as an aside it is also now possible in 12c to use interval partitioning on reference partitioned tables. In 11g it was not possible to combine these two new partitioning features. For our first example of the new 12cfunctionality, let us add all the partitions necessary for 2008 to the tables using one command. Notice that the partition specification part of the add command is identical in format to the partition specification part of the create command as shown above - SQL alter table orders add PARTITION Q1_2008 VALUES LESS THAN (TO_DATE('01-APR-2008','DD-MON-YYYY')), PARTITION Q2_2008 VALUES LESS THAN (TO_DATE('01-JUL-2008','DD-MON-YYYY')), PARTITION Q3_2008 VALUES LESS THAN (TO_DATE('01-OCT-2008','DD-MON-YYYY')), PARTITION Q4_2008 VALUES LESS THAN (TO_DATE('01-JAN-2009','DD-MON-YYYY')); Table altered. Now look at DBA_TAB_PARTITIONS and we can see that the 4 new partitions have been added to both tables – SQL select table_name,partition_name, partition_position position, high_value from dba_tab_partitions where table_owner='SH' and table_name like 'ORDER_%' order by partition_position, table_name; TABLE_NAME PARTITION_NAME POSITION HIGH_VALUE -------------- --------------- -------- ------------------------- ORDERS Q1_2007 1 TIMESTAMP' 2007-04-01 00:00:00' ORDER_ITEMS Q1_2007 1 ORDERS Q2_2007 2 TIMESTAMP' 2007-07-01 00:00:00' ORDER_ITEMS Q2_2007 2 ORDERS Q3_2007 3 TIMESTAMP' 2007-10-01 00:00:00' ORDER_ITEMS Q3_2007 3 ORDERS Q4_2007 4 TIMESTAMP' 2008-01-01 00:00:00' ORDER_ITEMS Q4_2007 4 ORDERS Q1_2008 5 TIMESTAMP' 2008-04-01 00:00:00' ORDER_ITEMS Q1_2008 5 ORDERS Q2_2008 6 TIMESTAMP' 2008-07-01 00:00:00' ORDER_ITEM Q2_2008 6 ORDERS Q3_2008 7 TIMESTAMP' 2008-10-01 00:00:00' ORDER_ITEMS Q3_2008 7 ORDERS Q4_2008 8 TIMESTAMP' 2009-01-01 00:00:00' ORDER_ITEMS Q4_2008 8 Next, we can drop or truncate multiple partitions by giving a comma separated list in the alter table command. Note the use of the plural ‘partitions’ in the command as opposed to the singular ‘partition’ prior to 12c– SQL alter table orders drop partitions Q3_2008,Q2_2008,Q1_2008; Table altered. Now look at DBA_TAB_PARTITIONS and we can see that the 3 partitions have been dropped in both the two tables – TABLE_NAME PARTITION_NAME POSITION HIGH_VALUE -------------- --------------- -------- ------------------------- ORDERS Q1_2007 1 TIMESTAMP' 2007-04-01 00:00:00' ORDER_ITEMS Q1_2007 1 ORDERS Q2_2007 2 TIMESTAMP' 2007-07-01 00:00:00' ORDER_ITEMS Q2_2007 2 ORDERS Q3_2007 3 TIMESTAMP' 2007-10-01 00:00:00' ORDER_ITEMS Q3_2007 3 ORDERS Q4_2007 4 TIMESTAMP' 2008-01-01 00:00:00' ORDER_ITEMS Q4_2007 4 ORDERS Q4_2008 5 TIMESTAMP' 2009-01-01 00:00:00' ORDER_ITEMS Q4_2008 5 Now let us merge all the 2007 partitions together to form one single partition – SQL alter table orders merge partitions Q1_2005, Q2_2005, Q3_2005, Q4_2005 into partition Y_2007; Table altered. TABLE_NAME PARTITION_NAME POSITION HIGH_VALUE -------------- --------------- -------- ------------------------- ORDERS Y_2007 1 TIMESTAMP' 2008-01-01 00:00:00' ORDER_ITEMS Y_2007 1 ORDERS Q4_2008 2 TIMESTAMP' 2009-01-01 00:00:00' ORDER_ITEMS Q4_2008 2 Splitting partitions is a slightly more involved. In the case of range partitioning one of the new partitions must have no high value defined, and in list partitioning one of the new partitions must have no list of values defined. I call these partitions the ‘everything else’ partitions, and will contain any rows contained in the original partition that are not contained in the any of the other new partitions. For example, let us split the Y_2007 partition back into 4 quarterly partitions – SQL alter table orders split partition Y_2007 into (PARTITION Q1_2007 VALUES LESS THAN (TO_DATE('01-APR-2007','DD-MON-YYYY')), PARTITION Q2_2007 VALUES LESS THAN (TO_DATE('01-JUL-2007','DD-MON-YYYY')), PARTITION Q3_2007 VALUES LESS THAN (TO_DATE('01-OCT-2007','DD-MON-YYYY')), PARTITION Q4_2007); Now look at DBA_TAB_PARTITIONS to get details of the new partitions – TABLE_NAME PARTITION_NAME POSITION HIGH_VALUE -------------- --------------- -------- ------------------------- ORDERS Q1_2007 1 TIMESTAMP' 2007-04-01 00:00:00' ORDER_ITEMS Q1_2007 1 ORDERS Q2_2007 2 TIMESTAMP' 2007-07-01 00:00:00' ORDER_ITEMS Q2_2007 2 ORDERS Q3_2007 3 TIMESTAMP' 2007-10-01 00:00:00' ORDER_ITEMS Q3_2007 3 ORDERS Q4_2007 4 TIMESTAMP' 2008-01-01 00:00:00' ORDER_ITEMS Q4_2007 4 ORDERS Q4_2008 5 TIMESTAMP' 2009-01-01 00:00:00' ORDER_ITEMS Q4_2008 5 Partition Q4_2007 has a high value equal to the high value of the original Y_2007 partition, and so has inherited its upper boundary from the partition that was split. As for a list partitioning example let look at the following another table, SALES_PAR_LIST, which has 2 partitions, Americas and Europe and a partitioning key of country_name. SQL select table_name,partition_name, high_value from dba_tab_partitions where table_owner='SH' and table_name = 'SALES_PAR_LIST'; TABLE_NAME PARTITION_NAME HIGH_VALUE -------------- --------------- ----------------------------- SALES_PAR_LIST AMERICAS 'Argentina', 'Canada', 'Peru', 'USA', 'Honduras', 'Brazil', 'Nicaragua' SALES_PAR_LIST EUROPE 'France', 'Spain', 'Ireland', 'Germany', 'Belgium', 'Portugal', 'Denmark' Now split the Americas partition into 3 partitions – SQL alter table sales_par_list split partition americas into (partition south_america values ('Argentina','Peru','Brazil'), partition north_america values('Canada','USA'), partition central_america); Table altered. Note that no list of values was given for the ‘Central America’ partition. However it should have inherited any values in the original ‘Americas’ partition that were not assigned to either the ‘North America’ or ‘South America’ partitions. We can confirm this by looking at the DBA_TAB_PARTITIONS view. SQL select table_name,partition_name, high_value from dba_tab_partitions where table_owner='SH' and table_name = 'SALES_PAR_LIST'; TABLE_NAME PARTITION_NAME HIGH_VALUE --------------- --------------- -------------------------------- SALES_PAR_LIST SOUTH_AMERICA 'Argentina', 'Peru', 'Brazil' SALES_PAR_LIST NORTH_AMERICA 'Canada', 'USA' SALES_PAR_LIST CENTRAL_AMERICA 'Honduras', 'Nicaragua' SALES_PAR_LIST EUROPE 'France', 'Spain', 'Ireland', 'Germany', 'Belgium', 'Portugal', 'Denmark' In conclusion, I hope that DBA’s whose work involves maintaining partitions will find the operations a bit more straight forward to carry out once they have upgraded to Oracle Database 12c.

• dist-update kernel failed?

  - by AlbertK

  I run: sudo apt-get update sudo apt-get dist-upgrade , and the linux kernel seemed to be updated to 3.2.0-31-generic successfully. However, after I rebooted, I typed: uname -a , it showed : Linux Albert-PC 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Does that means the kernel wasn't being updated? I didn't encounter any error or warning messages during the upgrade or dist-upgrade. Thanks for any help

• Problems uploading package to launchpad

  - by user74513

  I'm having a lot of problems uploading my showdown project to a PPA. I've setup correctly PGP keys and my public ssh key to launchpad. I've packaged with debuild my C++ project, producing a source package lintian gave me only those two warnings that I think are ok for the showdown rules: W: massren source: native-package-with-dash-version W: massren source: binary-nmu-debian-revision-in-source 1.0-0extras12.04.1~ppa2 Producing a binary package works to and the package installs without problem on my ubuntu 12.04 machine, I only have a few more lintian warnings about the fact I'm installing in /opt/extras.ubuntu.com/ I'm uploading with: dput ppa:gabrielegreco/massren massren_1.0-0extras12.04.1~ppa2_source.changes When I upload with dput I have no errors, signatures seems ok, and public key seems accepted to (since the upload goes on without asking passwords...): dput ppa:gabrielegreco/massren massren_1.0-0extras12.04.1~ppa2_source.changes Checking signature on .changes gpg: Signature made Mon 02 Jul 2012 10:00:38 AM CEST using RSA key ID 49982576 gpg: Good signature from "Gabriele Greco " Good signature on /home/gabry/no-backup/massren_1.0-0extras12.04.1~ppa2_source.changes.

Any idea how can I solve this problem? I'm new to ubuntu packaging, so I may miss some step... There is an alternative to dput (aka manual upload)?
