Installation

Informix DS 9.21.UC4-2

Reference system: SUSE Linux 8.1 Professional [Basel - privat]

1. Preparations

There must be a group and user "informix".

The Informix products must be installed in a specific order if you are installing client and server products in the same $INFORMIXDIR directory:

  • SQL software
  • Database server
  • Client SDK

Read the Informix installation guide for further instructions.

2. Creation of the Informix directory

Observe the following guidelines:

  • Use the same directory to install both Dynamic Server and any local client products
  • The INFORMIXDIR should be /opt/informix (SISIS-default for Linux)
  • Create the directory on a local drive
  • Documentation can be found under /opt/informix/release/en_us/0333

Create the product directory $INFORMIXDIR:

# mkdir /opt/informix
# chown -R informix /opt/informix

Set $INFORMIXDIR and put $INFORMIXDIR/bin in the PATH:

# export INFORMIXDIR=/opt/informix
# PATH=$PATH:$INFORMIXDIR/bin

Create the following entry in /etc/services :

# vi /etc/services
sqlturbo 1526/tcp # Informix

3. Installation of the Informix-SQL package from CD-ROM

Insert the CD-ROM.

# mount /cdrom
# cd $INFORMIXDIR
# tar xvf /cdrom/sql.tar
...
Enter your serial number:
Enter your serial number KEY:
...
# cd

# eject

If only the runtime version is installed:

# mount /cdrom
# cd $INFORMIXDIR
# tar xvf /cdrom/sqlrt.tar
# cd
# eject

4. Installation of the Informix Dynamic Server package from CD-ROM

After inserting the CD-ROM:

# mount /cdrom
# cd /cdrom/IDS
# rpm -iv ids.rpm

6. Configuration of the database server

Next is the configuration of the Dynamic Server. First the disk spaces for the needed dbspaces have to be allocated.

Note: The physdbs and the datadbs (sikisdbs, siasdbs, sieradbs) should not reside on the same disk. So place the datadbs and tempdbs on the system disk but rootdbs, physdbs and logdbs on the second disk. If more disks are available, then divide the dbspaces more. Raw-devices are not supported!

Edit the file .profile of the user "informix":

# vi /home/informix/.profile
export INFORMIXDIR=/opt/informix
PATH=$PATH:$INFORMIXDIR/bin
export INFORMIXSERVER=sisis
export ONCONFIG=onconfig.sisis

The directory /DBinformix,where the cooked space will reside as user "informix", already exists:

# chown informix:informix /DBinformix
# su - informix
$ cd /DBinformix
$ cat /dev/null > rootdbs
$ cat /dev/null > sisisdbs
$ cat /dev/null > tempdbs

If necessary, also create the following dbspaces:

$ cat /dev/null > physdbs
$ cat /dev/null > logdbs
$ cat /dev/null > sikisdbs
$ cat /dev/null > siasdbs
$ cat /dev/null > sieradbs

$ chmod 660 *dbs
                                                    
$ cd /home/informix
$ mkdir links
$ cd links
$ ln -s /DBinformix/rootdbs rootdbs
$ ln -s /DBinformix/sisisdbs sisisdbs
$ ln -s /DBinformix/tempdbs tempdbs

If necessary, also link the following dbspaces:

$ ln -s /DBinformix/physdbs physdbs
$ ln -s /DBinformix/logdbs logdbs
$ ln -s /DBinformix/sikisdbs sikisdbs
$ ln -s /DBinformix/siasdbs siasdbs
$ ln -s /DBinformix/sieradbs sieradbs

The file $INFORMIXDIR/etc/sqlhosts must have the following syntax:

<database servername> <protocol> <hostname> <service>

In our example the file /opt/informix/etc/sqlhosts has the following entries:

sisis onipcshm sh-dz sisis_shm
sisis_tcp onsoctcp sh-dz sqlturbo

The next step is to create the file $INFORMIXDIR/etc/onconfig.sisis :

$ cd /opt/informix/etc
$ cp onconfig.std onconfig.sisis

It is strongly recommended to alter the following parameters to the given values (according to our example):

ROOTPATH        /home/informix/links/rootdbs    # Device containing root dbspace
ROOTSIZE        200000                          # Size of root dbspace (Kbytes)

JVPCLASSPATH    /opt/informix/extend/krakatoa/krakatoa_g.jar:/opt/informix/extend/krakatoa/jdbc_g.jar

Now create the tape device path and also the log tape device path:

$ cd /home/informix
$ mkdir sicherung.sisis
$ chmod 775 sicherung.sisis
$ cd sicherung.sisis
$ cat /dev/null > level0
$ chmod 666 level0
$ mkdir logfiles
$ chmod 775 logfiles

Now initialize the server "sisis".

$ oninit -i
This command initializes the Informix Dynamic Server 2000; any existing Informix Dynamic Server 2000 databases 
  will NOT be accessible - Do you wish to continue (y/n)? y

Don't get nervous - this may take some minutes!

Note: Check the file online.log for the entries:

'sysmaster' database built successfully.
'sysutils' database built successfully.

Monitor the operation of the database server, showing the dbspaces and chunks.

$ onstat -d
Informix Dynamic Server 2000 Version 9.21.UC4  -- On-Line -- Up 00:12:18 -- 41312 Kbytes

Dbspaces
address  number   flags    fchunk     nchunks  flags    owner    name
10a277d0 1        0x1        1        1        N        informix rootdbs
 1 active, 2047 maximum

Chunks
address  chk/dbs offset  size    free    bpages   flags pathname
10a27918 1   1   0       100000  91732            PO-   /home/informix/links/rootdbs
 1 active, 2047 maximum

Create the the dbspace "sisisdbs":

$ onspaces -c -d sisisdbs -p /home/informix/links/sisisdbs -o 0 -s 2000000

If necessary, also create the following dbspaces:

$ onspaces -c -d sisisdbs -p /home/informix/links/logdbs -o 0 -s <size in pages>
$ onspaces -c -d sisisdbs -p /home/informix/links/physdbs -o 0 -s <size in pages>
$ onspaces -c -d sisisdbs -p /home/informix/links/siasdbs -o 0 -s <size in pages>
$ onspaces -c -d sisisdbs -p /home/informix/links/sieradbs -o 0 -s <size in pages>
$ onspaces -c -d sisisdbs -p /home/informix/links/sikisdbs -o 0 -s <size in pages>

Finally create the dbspace "tempdbs" with these options:

$ onspaces -c -t -d tempdbs -p /home/informix/links/tempdbs -o 0 -s 1000000

After this change the variable DBSPACETEMP in the file $INFORMIXDIR/etc/onconfig.sisis (this can only be done now!):

$ vi /opt/informix/etc/onconfig.sisis
DBSPACETEMP	/home/informix/links/tempdbs     # Default temp dbspaces

At last perform a level0 archive (the archive will be created at $TAPEDEV/level0 ):

$ ontape -s -L 0
