Cs_dt_info for Client Library). Sybperl provides access to this function, as does dbd:Sybase. sybase central on linux Sybase.9.2 includes the sybase central gui admin tool, but only for Win32 machines. For a native linux app you should check out like sybase central a freeware tool developped by pascal Ginola, available from /laserquest/linux/ As of ase.5 Sybase central is written in java, and runs fine under linux. It is included in the.5 release. Placing tempdb on a ram disk first, add ram disk support to your kernel by setting config_BLK_DEV_ram. This can be done by running make menuconfig or make xconfig in the /usr/src/linux directory and enabling ram disk support in the Block devices section.
System, admin, simple helix
This should properly set the network Address field as "m,2345" and the network library field to dbmssocn (or default as well. Do not select "Use trusted connection". Step 6 (optional Press the Options button to configure a specific database name, choose a language, and/or select other options. Dismiss this window when you're done. What won't work after you do this: any tool that has built in knowledge of the details of MS/sql server's platform-specific ddl/DML/sql and generates this for summary you through a gui will eventually send the wrong sql if you try enough database administration functions. Also, we were unable to make a java jdbc client work against Sybase using the ms/sql odbc drivers, although Perl dbi:odbc does appear to work. date formats This is for the.0.4 version of OpenClient (ie the one that is included in the free release.) There is what I consider a bug in the locale handling of OpenClient on linux. By default, when doing a "select getdate you get only "01/15/99" in the result, instead of the more normal "Jan :50AM" format that you normally get on other platforms. This can be fixed (somewhat) by editing and commenting out the dateformatmdy line. Another option is to change the default date conversion format by using the OpenClient api (e.g.
MS2linux) and a value of "dbmssocn, m,2345" (assuming your dll for tcp/IP sockets is named the same as mine). Step 3: (Here, i'm describing the nt ere may not be a distinction between user and system dsn in Windows 9x). Under "Settings-control Panels-odbc" select the User lined dsn or System dsn tab depending on whether only the logged on user or all nt users on this machine should see the data source. Press the Add button. Step 4: In the resultant "Create new Data source" window, select "Microsoft sql server" or "sql server" (these are synonyms on my system). Step 5: Supply a data source name and Description (the name is arbitrary, and doesn't need to match anything else, but should presumably be mnemonic). Pull down the server selection and choose the server you configured in Step.
Step 1: Execute the sql server Client Configuration Utility (could appear in the microsoft sql server.5 program group on your start menu if that's the version you are running). Step 2: Under the 'advanced' tab name your Linux/ase server something meaningful in the 'server' field, eg MS2linux. In the dll name tab, select 'tcp/ip sockets'. In the connection String field, enter the dns name and port matching your Linux ase machine and its interface file. Port number should be separated by a comma from the dns name. M,2345 Note that real it doesn't matter which port you use, so long as you make it match the port that Sybase is using on the linux side, as specified thesis in your interfaces file. Press the "Add/Modify" button to add this entry to the Advanced Client Options list box. This creates a registry entry under with the name you gave (e.g.
To install Wisqlite, simple copy 'wisqlite' from the./samples directory to /usr/bin. Edit /usr/bin/wisqilite and change the top line to: !/usr/bin/wish8.0 connecting from Win NT/95/98 see the Draft how-to on Connecting from Windows Clients by Shaun Lipscombe for a fairly complete write-up. Sybase normally distributes the windows client libraries when you buy a server for any platform. The.9.2 release for linux includes the pc client tools (including Sybase central) and these can be used to connect to the linux server. I'm not 100 sure what the licencing issues are with this package - you can download the win32 client, but this is theoretically for development use only. You are supposed to pay a licence fee for production use (at least for the server - again I don't know what the situation is exactly for the win32 client tools - contact Sybase if you are in doubt.) These files are available from. There are odbc drivers are available from Openlink software at m and you can also use the ms-sql drivers if you configure the sybase data source as follows (submitted by carol Lerche ) Using mssql's client support to access Sybase ase on Linux: First, realize. Exe) use the ms/sql version of dblib directly, and some (such as Perl dbi) use it through odbc, so you probably should start by configuring the sybase server as a ms/sql dblib client.
All about linux jobs: Windows / Unix, system, admin, top
This entails a significant performance hit, and can be controlled on a per-device basis via the sp_deviceattr stored procedure using the dsync option. In addition, chattr s file forces the O_sync flag to be used for a file regardless of whether ase has it enabled on not. raw disk I/O doesn't work (RH.2,.x, suse.) When Wim added Raw pizza io support to ase the beta raw io kernel patch for.1 was using a specific device layout, which the rh engineers then saw fit to change for.2. Suse and maybe others also follow this device layout. In.1 the raw device administration to bind devices was via /dev/raw. In.2 (and later) rh decided to reorganize this, using /dev/rawctl for the device binding and a /dev/raw directory to hold the raw devices. Sybinit tries to use the original /dev/raw for binding the devices and a /dev/sybase directory for the devices themselves, which fails under.2 and later.
This can be fixed like this: First, become root (and be careful what you do next!) go to the devices directory cd /dev make sure no raw device binding is active, and no servers that depend on this stuff are running. Move the 'raw' directory to 'sybase mv raw sybase Create a symbolic link for the administration device ln -s /dev/rawctl /dev/raw make sure you have the access permissions to the bind device, raw devices and the partitions that are bound to raw devices. You should follow the instructions from the configure file from here. Now if you restart sybinit it should automatically detect the device size for the raw device bound to the partition that you want to use as master device (or whatever.) building Sybtcl on linux Sybtcl builds 'out of the box' on Linux, assuming you have. Tcl.0 or higher is recommended. RedHat versions.1 and higher include Tcl/Tk.0. To build Sybtcl, simply unpack the sybtcl distribution, change to the sybtcl-2.5/unix directory, and: configure make make install you must be 'root' to install into the /usr directories.
The fix for this is to change the stop section in the sybase rc script to perform a real shutdown instead of calling killproc. Change stop) echo -n "Shuting down Sybase ase configured servers: " killproc dataserver killproc backupserver killproc monserver Add your own openserver applications. Echo ; to stop) echo -n "Stopping Sybase sql server" sybase/bin/isql -Usa -p* -sdsquery stopit shutdown syb_backup with nowait go shutdown go exit stopit killproc monserver Add your own openserver applications. Echo ; Obviously you need to edit the above to set the password to isql correctly, and you need to make sure that dsquery is set correctly in the script (or you may want to hard code it). You also need to duplicate the code if you have more than one sql server running.
Mike chachich has pointed out to me that this shutdown technique might not work well (or might take a long time) on a very busy system. He suggests issueing checkpoint requests for each database, kill all user processes and then issue a shutdown after all user processes have exited. You would have to write a small script (perl, anyone?) to do this, but it should be fairly simple. raw disk I/o raw disk I/O is available with ase and ase.5 and later. It is not available when using ase.9.2. The.9.2 and later releases use the O_sync flag for all the open(2) calls when using filesystem devices, which forces the kernel to flush the data from the filesystem cache to disk after each and every write.

Local (or its equivalent on your system) to have this run at boot. The following is only valid if you are still using.0.x kernel: If you are using.0.x kernel, you need to edit and change the salon line that says define shmmax 0x2000000 max shared seg size (bytes) to define shmmax 0x4000000 max shared seg. In addition it seems that linux by default will only recognize 64 megabytes of ram. To go beyond that you have to add a yardage "mem" entry to the nf file, and then run lilo for it to take. One correspondant tells me he has 256 mb ram on his linux box, and his nf looks like this: boot/dev/sda3 map/map install/boot. B prompt timeout50 image/vmlinuz labellinux root/dev/sda3 initrd/boot/g append"mem256M" read-only note the append"mem256M" line in extract above. sybase rc scripts and identity columns The rc scripts that are provided with the ase and.9.2 releases use the killproc facility to kill the servers when you execute the stop command (eg, on RedHat /etc/rc. D/sybase stop ) It turns out that this essentially tells the server to perform a shutdown with nowait, which has negative effects on any identity columns in your databases (ie causes large gaps in the values that are generated).
This site is widely mirrored, and you can reach a site closer to you by changing the us in the hostname to your country code ( au for Australia, uk for the uk, fi for Finland, etc.) Note that this site can also be accessed. It is only necessary to upgrade the kernel on the machine that is running the server. Clients can run earlier versions of the kernel with no problems. configuring memory by default the linux kernel is limited to 32 megabytes of shared memory. You will thesis need to increase that value in order to install Sybase ase. For.4.x kernels the simplest way is to edit /etc/nf, and add a mmax line. The running /sbin/sysctl -p applies the changes (and the changes get applied automatically at boot). My /etc/nf has the following line: mmax which sets the maximum shared memory segment to 256MB. You can also update the value in the /proc filesystem directly, via the following command: echo /proc/sys/kernel/shmmax you can place this command in /etc/rc.
to validate that your os configuration is correct - better to find out about any problems before starting the install. The script. Where do i get the software? The current free release of Adaptive server Enterprise for linux is available for download from. You will be asked to fill in a simple registration form after which you can proceed with the download. connecting to the server There is a tcp/IP bug in the.0.xx linux kernels, where xx is lower than. This bug has been fixed by Alan Cox for the.0.36 kernel. If you need to connect to the server from a different machine you should be running the.0.36 kernel, or the.1.122 (or later) development kernel. You can download the kernels from ftp:rnel.
In a recent post to the ase on Linux mailing list, teresa larson listed the major other, sybase-related resources that are available on the net: Well, the ase-linux list will also help with questions/problems/issues on the sybase server itself - it's not a linux-only list. As for other resources, for self-help, sybase provides their documentation on-line at m other forums where you can post Sybase questions are: father's base - this is a public usenet news group. It's been around for a long time and you'll find people with lots of experience as well as some really nice sybase engineers participating. Sybase-l - this is a listserver mailing list that has been around for years. Like base, you'll find people with lots of experience along with really nice sybase engineers. To join the list, send a subscribe message (subscribe sybase-l ur_firstname, ur_lastname) to m/newsgroups - this site is hosted by sybase and has forums for a variety of topics (e.g., neral, ministration, nux, ase. The site has instructions on how to set up your browser to access the news groups. Those are the biggies. I hope it helps.
