SQL 2008 R2 replication error: The process could not connect to Distributor

- by Lance Lefebure

I have two servers running SQL 2008 R2 Standard, each with an instance named "MAIN". I have a small test database on my primary server (one table, 13 rows) that I want to replicate to a second server as a proof-of-concept for some larger databases that I want to replicate. I set up the primary server to be a publisher and distributor, and set the database to do transactional replication. I copied the data to the second server via a backup/restore, not via a snapshot (which I'll have to do with the larger databases due to database size and limited bandwidth). I followed the instructions here: http://gnawgnu.blogspot.com/2009/11/sql-2008-transactional-replication-and.html Now on the subscriber, I go under Replication / Local Subscriptions / Right click / Properties on my subscription to the DB. The status of the last synchronization shows a status of: "The process could not connect to Distributor 'PRIMARYSERVER\MAIN'." Data IS replicating from the primary to the secondary. Any record I add on the primary shows up on the secondary server within seconds. Is the Distributor part of the Snapshot system that I'm not using, or is it part of the transaction replication stuff? Thanks, Lance

Time Machine is getting stuck at "Preparing to Back Up" and my Trash isn't emptying

- by zarose

I have encountered two separate problems, but I am putting them in the same question in case they are related. First, my Trash would not empty. It seems to be getting stuck on certain files, because I will reset my Macbook and some of the files will be deleted, and then if I remove a file or two at random, more can be deleted. Some of these files had strange characters in their names. I tried changing the names to single characters, but this did not help. Next, I attempted to backup my Macbook using Time Machine. I plugged in the HDD I've been using for this, but every time I try to start the backup, Time Machine gets stuck at "Preparing to Back Up". I definitely need to know how to fix the Time Machine problem, but I am curious how to solve the trash problem as well, and whether or not these problems are related. EDIT: Console.app logged the following this morning before I left on a trip. I did not bring the HDD with me. 6/5/12 7:41:28.312 AM com.apple.backupd: Starting standard backup 6/5/12 7:41:46.877 AM com.apple.backupd: Error -35 while resolving alias to backup target 6/5/12 7:41:58.368 AM com.apple.backupd: Backup failed with error: 19 6/5/12 7:59:08.999 AM com.apple.backupd: Starting standard backup 6/5/12 7:59:10.187 AM com.apple.backupd: Backing up to: /Volumes/Seagate 3TB Mac/Backups.backupdb 6/5/12 7:59:13.308 AM com.apple.backupd: Event store UUIDs don't match for volume: Macintosh HD 6/5/12 7:59:13.331 AM com.apple.backupd: Event store UUIDs don't match for volume: Blank 6/5/12 7:59:13.683 AM com.apple.backupd: Deep event scan at path:/ reason:must scan subdirs|new event db| 6/5/12 8:23:31.807 AM com.apple.backupd: Backup canceled. 6/5/12 8:23:33.373 AM com.apple.backupd: Stopping backup to allow backup destination disk to be unmounted or ejected. 6/5/12 9:51:21.572 PM com.apple.backupd: Starting standard backup 6/5/12 9:51:22.515 PM com.apple.backupd: Error -35 while resolving alias to backup target 6/5/12 9:51:32.741 PM com.apple.backupd: Backup failed with error: 19

Migrate Maildir between courier and dovecot servers

- by DeaconDesperado

I have several tarballs that make up all the previous emails for two or three accounts on a mail server. This machine we be shut down within a few weeks and so I need to migrate all the previously subscribed IMAP folders to the new server. The old machine ran Dovecot with exim and delivered all mail to a virtual user folder on the server in maildir format. The new machine uses courier and postfix, also configured to deliver through maildir. The new server is already setup and all clients are successfully logging in, the problem is migrating their old conversations. I've tried moving the old message files directly and deleting the imap db that records which messages have already been fetched, but nothing has been successful. The outlook clients present an error for every message saying that the "message can no longer be located on the server." Keeping the files chronologically sorted is not an object, I just need to migrate the old conversations over. Is there a way to do this in a batch operation that will allow the clients to login to the new server and treat these old messages as though they were new? What is the protocol for this kind of migration?

How to setup port forwarding from my Webserver (apache) to my Database server (mysql)

- by karman888

Hello again guys, and thank you for your help so far. Here is my problem: I have two remote dedicated servers, one webserver that runs apache, and one db server that runs mysql. The apache server is visible on the internet of course, but the second server is only visible to the apache server because they are connected with LAN. I need to connect to the remote mysql server through internet from my home-pc , but only apache server is visible to my home-pc. How can i setup port-forwarding from my apache server to the mysql server so i will be able to "see" the mysql server from my home-pc? This question is a follow-up from my first question Connect to remote mysql server from my application. Problem is that Mysql server is on LAN in which you answered me and helped me a lot by telling me to do "port-forwarding". I looked over the internet, and i cant find a good how-to to do port-forwarding. I'm an experienced programmer, but have little experience on hardware and networks. I can understand though what must be done, so i just need a litle help to sort things out :) I hope you can help me guys, Thank you in advance p.s. machine that Apache is running is on CentOS, mysql server also CentOS. p.s2 webserver runs WebHostManager i dont know if that makes any difference or it can be made easily through this, i just mention it :)

Strange 400 error with IIS 7.5 and a webservice?

- by Juw

Ok, this is a longshot. I have been pondering this for hours. I have no clue how to solve this. But maybe someone here can recognize the problem and point me to right direction. I have an IIS 7.5 server and a MSSQL database on a different server. On the IIS server there is a webservice that communicates with the MSSQL server. The problem is that when there is data that the MSSQL server needs to send back to the webservice and the webservice delivers that back to the webbrowser (JSON) i get a 400 error. Looking through the logs for the IIS there is just a 400....nothing more. When i put in a call to the service in my browsers URL field i get this: "The server encountered an error processing the request. Please see the service help page for constructing valid requests to the service." There is NOTHING wrong with how i call the webservice. It has worked before on a different server (a dev server). Do someone have a clue on what this can be about? 400 means malformed URL...it isn´t. And why is that when there are no data to return to the user...everything works. But when there is data fetched from the MSSQL DB...the 400 error shows up. Hope someone have some tips how to solve it. Thanx in advance.

Sampling the process points back to the MAMP mysqld.. wtf?! About to throw MAMP out the window and boot up a VM of CentOS =)

How can the route between two private IPs go via public IPs?

- by Gilles

I'm trying to understand what this output from traceroute means. I changed the IP addresses for privacy but retained the public/private IP range distinction. traceroute.db -e -n 10.1.1.9 traceroute to (10.1.1.9), 30 hops max, 60 byte packets 1 10.0.0.1 0.596 ms 0.588 ms 0.577 ms 2 10.0.0.2 1.032 ms 1.029 ms 1.084 ms 3 10.0.0.3 3.360 ms 3.355 ms 3.338 ms 4 23.0.0.4 3.974 ms 4.592 ms 4.584 ms 5 23.0.0.5 13.442 ms 13.445 ms 13.434 ms 6 45.0.0.6 13.195 ms 12.924 ms 12.913 ms 7 67.0.0.7 52.088 ms 51.683 ms 52.040 ms 8 10.1.1.8 46.878 ms 44.575 ms 44.815 ms 9 10.1.1.9 45.932 ms 45.603 ms 45.593 ms The first 10.0.* range is inside my organisation. The last 10.1.* range is another site of my organisation. The intermediate addresses belong to various ISPs. I expect that there is some kind of VPN between the two sites, but I don't know much about our network topology. What I don't understand is how the route can go from a private address through public addresses back into private addresses. Searching led me to Public IPs on MPLS Traceroute, which gives a possible explanation: MPLS. Is MPLS the only possible or most likely explanation? Otherwise what does this tell me about our network infrastructure? Bonus question for my edification: in this scenario, who is generating the ICMP TTL exceeded packets and if relevant mangling their source and destination addresses?

Can MySQL use multiple data directories on different physical storage devices

- by sirlark

I am running MySQL with its data dir on a 128Gb SSD. I am dealing with large datasets (~20Gb) that are loaded and processed weekly, each stored in a separate DB for the purposes of time point comparisons. Putting all the data into a single database in unfeasible because the performance on such large databases is already a problem. However, I cannot keep more than 6 datasets on the SSD at a time. Right now I am manually dumping the oldest to much larger 2Tb spinning disk every week, and dropping the database to make space for the new one. But if I need one of the 'archived' databases (a semi regular occurrence) I have to drop a current one (after dumping), reload it, do what I need to, then reverse the results. Is there a way to configure MySQL to use multiple data directories, say one on the SSD and one on the 2Tb spinning disk, and 'merge' them transparently? If I could do this, then archiving would no longer mean "moved out of the database entirely", but instead would mean "moved onto the slow physical device". The time taken to do my queries on a spinning disk would be less than that taken to completely dump, drop, load, drop, reload two entire databases, so this is a win. I thought of using something like unionfs but I can't think of a way to control which database gets stored on which physical drive, because it works by merging on a directory level (from what I understand) so I'm still stuck with using multiple directories. Any help appreciated, thanks in advance

Moving a site from IIs6 to IIS7.5

- by Sukotto

I need to move a site off of IIS6 (Win Server 2003) and onto IIS7.5 (Win Server 2008) as soon as possible. Preferably tomorrow. The site itself is a delightful mix of classic asp (vbscript) and one-off asp.net (C#) applications (each asp.net app is in its own virtual dir and has a self-contained web.config). In case it's relevant, this is a sort of research site made up of 40 or 50 unconnected microsites. Each microsite is typically a simple form allowing a user to submit a form, which then runs a Stored Proc on a sqlserver db and displays a chart and/or table of the results. There is very little security to worry about. The database connection info is in a central file (in the case of the classic asp) or app's individual web.config (lots of duplication there) To add a little spice to the exercise... I have no idea how to admin IIS The company no longer employs the sysadmin or the guys who set this thing up. (They're not going to employ me much longer either but my sense of professional pride does not permit me to just walk away from this task). The servers are on mutually firewalled networks and I have to perform a convoluted, multi-step process to copy anything from one to the other. Would someone please point me to a crash-course tutorial for accomplishing the above? I have: a complete copy of the site's filesystem on the new box installed the 3rd party charting tool on the new system a config.xml file from the "all tasks - save configuration to a file" right click menu. There doesn't seem to be a way to import it on the new system however. The newer IIS manager has a completely different UI and I'm totally lost. Please help.

Postfix additional transports - is it working?

- by threecheeseopera

I have enabled two additional transports in my postfix config to deal with recipient domains that demand connection limiting, per the instructions here at serverfault. However, I have no idea if this is working or not; in fact, I think it is not working, due to the send speeds I am seeing in the logs. How might I determine if my additional transports are working? If they aren't, do you have any tips on figuring out why? And, do you have any comments on my particular configuration? (am I a bucket of fail?) I have enabled the additional transports in master.cf: smtp inet n - - - - smtpd careful unix - - n - 10 smtp -o smtp_connect_timeout=5 -o smtp_helo_timeout=5 cautious unix - - n - - smtp -o smtp_connect_timeout=5 -o smtp_helo_timeout=5 I have set up the transport mapping file /etc/postfix/transport: hotmail.com cautious: yahoo.com careful: gmail.com cautious: earthlink.net cautious: msn.com cautious: live.com cautious: aol.com careful: I have set up the transport mapping and some connection-limiting settings in main.cf: transport_maps = hash:/etc/postfix/transport careful_initial_destination_concurrency = 5 careful_destination_concurrency_limit = 10 cautious_destination_concurrency_limit = 50 Finally, I have run converted the transport file to a db per the postfix docs: #> postmap /etc/postfix/transport And then restarted postfix. I do see my transport_maps setting when I run postconf, but I do not see any of the transport-specific settings ('careful_xxx_yyy_zzz'). Also the mail logs do not appear to be different in any way to what they were previously. Thanks!!!

How to transform a csv to combine matching rows?

- by Christian Wolf

I have a CSV file with some transaction data. Let's say date, volume, price and direction (sell/buy). Additionally there is a ID for each transaction and on each closing transaction (the newer one) there is a reference to the corresponding transaction. Classical database referencing. Now I want to do some statistics and draw some plots. This could be done via Octave, LaTeX/TikZ, Gnuplot or whatever. To do this I need both buy and sell price in one row. My thought was to preprocess the CSV to get another CSV containing the needed information and then to do the statistics. In the end I'd like to have a solution based on scripts and not on a spreadsheet as data might change often (exported from online DB). My actual solution (see http://paste.ubuntu.com/6262822/ ) is a bash script that parses the CSV line by line and checks if there exists a corresponding transaction. If found, a new row is written to the destination CSV. If not a warning is printed. The bad news: For each row in the source file I have to read the whole file a few times. This causes long running times of 10sec for 300 lines. As the line number might rise soon (10k lines), this is not perfect. I am aware, that there are many shells to be opened in the script which might cause the performance problems. Now my questions: Is bash/awk/sed/.... a good way to do things? Should I first import all data into a "real" local database to use SQL? Is there an easy way to achieve the desired results?

jdbc4 CommunicationsException

- by letronje

I have a machine running a java app talking to a mysql instance running on the same instance. the app uses jdbc4 drivers from mysql. I keep getting com.mysql.jdbc.exceptions.jdbc4.CommunicationsException at random times. Here is the whole message. Could not open JDBC Connection for transaction; nested exception is com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was25899 milliseconds ago.The last packet sent successfully to the server was 25899 milliseconds ago, which is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. For mysql, the value of global 'wait_timeout' and 'interactive_timeout' is set to 3600 seconds and 'connect_timeout' is set to 60 secs. the wait timeout value is much higher than the 26 secs(25899 msecs). mentioned in the exception trace. I use dbcp for connection pooling and here is spring bean config for the datasource. <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource" > <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/db"/> <property name="username" value="xxx"/> <property name="password" value="xxx" /> <property name="poolPreparedStatements" value="false" /> <property name="maxActive" value="3" /> <property name="maxIdle" value="3" /> </bean> Any idea why this could be happening? Will using c3p0 solve the problem ?

MySQL ADO.NET Connector & MSSQL Integration Services

- by user1114330

Here I am, day three... attempting to sync a data view on a Windows Vista box (64 bit) running MSSQL 2012 and Visual Studio 2010. Sanity is slipping and hunger for progress fills my attention. I went through hell trying to get the MySQL ODBC drivers to get the job but to no avail...everyone seems to be lost and all the threads I can find are solutions that do not work for me. The problem: System DSN's not being seen by SSIS. SSIS DSN Not Showing as ODBC Data Source I make the decision to try out the ADO.NET connector...and to my surprise it is actually in the selection list in data sources in SSIS. So I take off running to create a Data Flow Task, create an ADO.NET Source (a local MSSQL DB)...all is good as usual. Then I move swiftly to creating a ADO.NET Destination, enter my credentials...wow, I am selecting a database finally on my linux server! Happy thinking that I finally have figured a way to get the job done. Then I move to mappings...nope, something is wrong...I am getting an error that hurts my eyes: Pipeline component has returned HRESULT error code 0xC0208457 from a a method call. Error at Data Flow Task [ADO NET Destination [81]]: Failed to get properties of external columns. The table name you entered may not exist or you do not have SELECT permission on the table object and an alternative attempt to get column properties through connection has failed. Detailed error messages are" You have an error in your SQL syntax check the manual that corresponds to your MySQL server version for the right syntax to use near "database".tablename" at line 1. The descriptor files on path C:\Program Files (x86)\Microsoft SQL Server\110\DTS\ProviderDescriptors\ does not contain schema information for connection of type MySQL.Data.MySqlClient.MySqlConnection. So it looks like it can't the information and therefore I cannot map the tables properly. Any ideas on this would be ultra helpful...thanks in advance to All!

DNSSEC - First Signature

- by Arancha

I'm testing DNSSEC with Bind 9.7.2-P2. I have a question regarding the first signature created over a zone that already exists. I'm using dynamic DNS. I create the first two keys: one KSK and one ZSK. According to https://datatracker.ietf.org/doc/draft-ietf-dnsop-dnssec-key-timing/, the first ZSK needs to be published for an interval equal to Ipub, before it can be active. I create the ZSK with a Publication date previous to its Activation date. I restart the service and I can see that the key is published at Publication date, but it's no active later, when Activation date arrives. This is the configuration of the zone dnssec.es at the named.conf file: zone "dnssec.es" { auto-dnssec maintain; update-policy local; sig-validity-interval 1; key-directory "dnssec/keys_dnssec"; type master; file "dnssec/db.dnssec.es"; }; Any clue??

Mesh Networked servers via vpn

- by microspino

I got a design idea and I would like to have some advice from SF about It. I have 5 customers with small real-estate databases. I've built for them a desktop app and now they would like to merge their database to share their data. I don't want to centralize everything in one place nor I want to do maintenance for servers. They told me also, that all of them in their offices, have little servers and maintenance guys available. Although everything seems suitable for web application, I had the idea to experiment something new: Any customer small-server wild be connected to the others in a sort of mesh network without a single point of failure and through VPNs. If one of the servers went down the customers could still connect to their databases from one of the other mesh networked servers instead of from the local one that is down. During normal operations all the servers sync the db with the others through VPNs. I can accept a half-day timing window of NON synched data, in other words, since I don't need real time synchronization, the server don't have to always stay in synch. I can migrate my data over to other Non-Sql technologies like CouchDB or Redis or whatever you suggest. As you can see I don't have a lot of constraints and although I could go with a web application I would like to delegate and decentralize support, data-privacy and management, as more as I can to my customers offices. Is that a crazy idea? Do you know If something similar exist? Which technology would you suggest?

Managing rolling deployments in the cloud

- by Josh Nankin

Recently I've been experimenting with various cloud management tools like RightScale, Scalr, custom scripts for managing a variety of servers, each hosting several roles (app, db, load balancer, job queues, etc). The one thing I find lacking in most solutions is a way to do rolling deployments, i.e. running deployments sequentially across a number of servers with the same role. For instance, I dont want to build all of my webservers at the same time, as that will almost definitely result in some down time or 500s for my customers. I'd rather have one or two servers build at a time, while other servers are still available to handle requests. The other alternative is obviously to launch new servers that automatically update themselves on boot, but this isn't as cost effective, and most likely requires more time for the build to complete (it's faster to build on an existing server than to launch a new server and kill old ones). We've all heard of the big companies having the famous "push to build" button (companies like Twilio, Etsy, etc.) but it seems that they all have custom implementations of this. I'm not talking about a simple ssh-loop, clusterssh, or even an mcollective - I preferably want something with a nice simple interface that allows me to specify something like a RightScript or a Scalr script to run on a set of servers with a specific role, and it builds them sequentially. Does any one know of easy ways to get this done, or is this a candidate for a new open source project?

Error code 1005 (errno: 121) upon create table while restoring MySQL database from a dump

- by Jonathan

I have a linux prod machine and a Win7 64bit dev machine. My workflow includes dumping the production MySQL database on the linux machine and restoring it in my local MySQL database on the windows machine (using SQLyog). This worked fine for a long time. Following some trouble, I formatted and reinstalled my windows dev machine. Since then I'm unable to restore the db on it. I keep receiving the following error: Query: CREATE TABLE `auth_group` ( `id` int(11) NOT NULL auto_increment, `name` varchar(80) collate utf8_unicode_ci NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `name` (`name`) ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci Error occured at:2010-06-26 17:16:14 Line no.:30 Error Code: 1005 - Can't create table 'ap_site.auth_group' (errno: 121) Notice that this is the first create table statement in the sql dump file. This error occurs both on MySQL Community Server 5.1.41 and 5.1.48 and with SQLyog Community 8.0.4 and 8.5.1. I really don't know what's different in my configuration from before the reinstall and now and why does it have this effect. Restoring from sql dump is something I need to keep on doing, so I need a permanent fix and not a tailored workaround.

Run a rails server on Amazon EC2 [on hold]

- by Jashwant

Context: I've tried rubber gem, but that does not fulfill my requirements ( I needed to deploy on existing instance, so don't recommend me rubber) So, I followed this excellent tutorial http://stackoverflow.com/questions/15535140/installing-ruby-2-0-and-rails-4-0-0beta-on-aws-ec2 Now, I have ruby 2.0 and rails 4.0.0 running on AWS EC2. I successfully ran the server with RDS (mysql) as db and default webrick as server ( Using command rails server ) But, I've read that webrick is a development server and shouldn't be used at production. What I tried: I googled and came up with some alternatives. Capistrano Nginx / apache with passenger Passenger with Capistrano Unicorn Puma My Question: What exactly is capistrano / passenger ? Are they middleware to ease my deployment process ? I don't see any difficulty in doing rails server command. If they are just middleware, nginx with passenger and capistrano does not make any sense ? Why would I add a learning curve ( to learn nginx, passenger and capistrano configs) just to run my server ? I can just use nginx to deploy my app. Can't I ? What combination should I use on Amazon EC2 (or may be at any some other production server).

Possible disk IO issue

- by Tim Meers

I've been trying to really figure out what my IOPS are on my DB server array and see if it's just too much. The array is four 72.6gb 15k rpm drives in RAID 5. To calculate IOPS for RAID 5 the following formula is used: (reads + (4 * Writes)) / Number of disks = total IOPS. The formula is from MSDN. I also want to calculate the Avg Queue Length but I'm not sure where they are getting the formula from, but i think it reads on that page as avg que length/number of disks = actual queue. To populate that formula I used the perfmon to gather the needed information. I came up with this, under normal production load: (873.982 + (4 * 28.999)) / 4 = 247.495. Also the disk queue lengh of 14.454/4 = 3.614. So to the question, am I wrong in thinking this array has a very high disk IO? Edit I got the chance to review it again this morning under normal/high load. This time with even bigger numbers and IOPS in excess of 600 for about 5 minutes then it died down again. But I also took a look at the Avg sec/Transfer, %Disk Time, and %Idle Time. These number were taken when the reads/writes per sec were only 332.997/17.999 respectively. %Disk Time: 219.436 %Idle Time: 0.300 Avg Disk Queue Length: 2.194 Avg Disk sec/Transfer: 0.006 Pages/sec: 2927.802 % Processor Time: 21.877 Edit (again) Looks like I have that issue solved. Thanks for the help. Also for a pretty slick parser I found this: http://pal.codeplex.com/ It works pretty well for breaking down the data into something usable.

Tables in the SQL Server "master" database, will they cause problems?

- by pepoluan

Folks, please be kind on me... I'm just an 'accidental' DBA due to our DBA resigned, so I'm totally a newbie in DBA... You see, I have this application, "ESET Remote Administration Server" (ERAS) that stores its logs and analysis on (originally) a local Access database. The decision was to migrate its database to a SQL Server 2008 R2 machine. ESET (the maker of the software) helpfully provided tools to perform such migration; unfortunately, being the DBA neophyte that I am, I didn't realize that I have to first create my own database (on the SQL Server side) and assign that database as the 'default' database for ERAS' ODBC connection. Now, the migration tool had successfully created a whole bunch of tables inside the "master" database. My questions: Should I leave things be as it is, or should I re-migrate the ERAS database to a different database? If you suggest me perform a re-migration, my plan is to (1) create a new instance, (2) create a new database within the new instance, (3) create a new ODBC System DSN on the ERAS server pointing to the new DB in step 2, (4) use ESET's migration tool to migrate from the current DSN to the new DSN. Do you think I missed a step there? Thanks beforehand for any guidance.

Good HTTP Monitoring tools

- by ffffff

I look for HTTP to work with a Linux system server monitor tool every protocol. I know, and will not there be it in whom or a freeware? When, for example, I dump 80/tcp with a packet monitor to be concrete # tethereal -i ppp0 port 80 -x Capturing on ppp0 1244206390.030474 219.111.xx.xx -> 74.125.xx.xx HTTP GET /search?output=js&num=0&dt=1244206414703&client=pub-3031568651010206&q=Cagliari%20Flight&ad=n3&ie=utf8&oe=utf8&channel=0091594208&adtest=off HTTP/1.1 0000 00 04 02 00 00 00 00 00 00 00 00 00 00 00 08 00 ................ 0010 45 00 01 e5 ee 82 40 00 40 06 d2 b5 db 6f 02 5b E.....@[email protected].[ 0020 4a 7d 4f 93 d4 29 00 50 3e df 4c 63 4b 6b 42 e0 J}O..).P>.LcKkB Such output is provided, but there is too much unnecessary information such as an SYN packet or a header.

I can set a filter and am the best if only information wanting can accumulate in the log.

How do I cancel windows server 2003 repair install?

- by Kilgore2k

System: Windows 2003 Server Enterprise Scenario: NTDS db is corrupt and all attempts to fix with esentutl fail. Ran chkdsk which seemed to repair disk error and give access to the ntds.dit file but still esentutl fails. (Attached the drive to a different server to run the esentutl) Error: Access to source database '[path to copy of]/ntds.dit' failed with Jet error -1022. Operation terminated with error -1022 (JET_errDiskIO, Disk IO error) after 0.170 seconds. This error occurs on any disk I cpoy the files to including original location in C:\WINDOWS\NTDS\ Now enter the "Stupid!" and "what was I thinking!?" part (must be the late hour...) Stupid: No updated backup - after using a backup I get a network password error in the lsass error. what was I thinking!?: Started the install repair from the original CD but the install fails since the AD fails to start. Now I cant boot into any mode (safe mode, AD restore etc) nor complete the repair install. I would really like to avoid a fresh install since I have the Exchange server on this DC and would rather migrate to a new server than have to start from scratch. Thanks!

Who should I run mysql as, on a personal computer?

- by user664833

I just installed mysql via homebrew (with brew install mysql, on Mac OS X Mountain Lion - recently installed from scratch). Following the installation, there is a "caveats" section with options around further necessary actions to take: ==> Caveats Set up databases to run AS YOUR USER ACCOUNT with: unset TMPDIR mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp To set up base tables in another folder, or use a different user to run mysqld, view the help for mysqld_install_db: mysql_install_db --help and view the MySQL documentation: * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html To run as, for instance, user "mysql", you may need to `sudo`: sudo mysql_install_db ...options... Start mysqld manually with: mysql.server start Note: if this fails, you probably forgot to run the first two steps up above A "/etc/my.cnf" from another install may interfere with a Homebrew-built server starting up correctly. To connect: mysql -uroot To launch on startup: * if this is your first install: mkdir -p ~/Library/LaunchAgents cp /usr/local/Cellar/mysql/5.5.27/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist * if this is an upgrade and you already have the homebrew.mxcl.mysql.plist loaded: launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist cp /usr/local/Cellar/mysql/5.5.27/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist You may also need to edit the plist to use the correct "UserName". On previous versions of Mac OS X I ran mysql as mysql user, but now I am confronted by the idea of running it as myself. I am the only one who uses this computer (which happens to be my laptop), and I do programming for work and for pleasure. What are the pros & cons, or best practices, around choosing whether to run mysql AS YOUR USER ACCOUNT or as mysql or something else still?
