Sybase IQ-15_1 local login problem of interfaces file configuration and data file permissions

    Environment description:
    Operating system: rhel 5.4
    Database version: Sybase IQ-15_1
    Problem description: A customer in Shanghai restarts the Sybase IQ-15_1 database host, and the Sybase IQ-15_1 database starts abnormally. Because the database administrator Sybase IQ-15_1 is
inexperienced, he cannot log in Local Sybase IQ-15_1 console.
    Problem handling process:
    1. First, solve the login problem of the iqdemo library.
    1. Find the iqdemo database process through ps -ef|grep sybase.
    2. Temporarily configure the local LANG parameters of the operating system. The export does
    not configure the operating system LANG parameters. The login error is as follows:
Your sybase home directory is /opt/sybase. Check the environment variable BYBASE if it is not the one you want!
Using local name "zh_cn.DGB" definied in environment variable  LANG locale name "zh_CN.GBK" doesn't exist  in your
/ opt/sybase/locales/locales.dat file
An error occurred when attempting to allocate localization-related structures.
The error message indicates the character setzh_CN.GBK atdoes not exist in /opt/sybase/locales/locales.dat
    3. Enter the sybase iq installation directory /opt/sybase/, find the interfaces file, and execute more interfaces without content. The
    interfaces configuration is as follows ( IQ is the host name, 2368 is the network port number in the demo library control file iqdemo.cfg file, pay attention to the interfaces configuration format ):
iqdemo
    master tcp ether IQ 2638
    query tcp ether IQ  2638
    --When interfaces are not configured, the login error is as follows:
CT-LIBRARY error: ct_connect():directory service layer:internal directory control layer error:Requested server name not found.
    
--When     the DNS resolution of the hostname configured by interfaces is incorrect (here refers to the tab space in front of the master query), the login error is reported:
CT-LIBRARY error: ct_connect():directory service layer:internal directory control layer error:Invalid syntax found in interfaces file.     --When the interface configuration format is incorrect, the login error: CT-LIBRARY error:
    


    ct_connect():network packet layer:internal net library error:Protocol driver call to parse connection information failed
--When     the interface configuration network port is not correct, login error:
CT-LIBRARY error:
    ct_connect():directory service layer:internal directory control layer error: Net-Lib protocol driver call to connect two endpoints failed
    4. After the interfaces file is configured correctly, use the sybase user to log in to the sybase iq console
$iqsql -UDBA -Psql -Siqdemo
>
    2. Deal with the user's business database startup permission problem
    1. The sybase user tries to start the tpaic library: start_iq @/opt/sybase/tpaic/tpaic.cfg /opt/sybase/tpaic/tpaic.db, an error is reported:

    2. The root user executes ls -l: ls -l /opt/sybase /tpaic/DSMSYS01.iq, found that the file is a soft link, linked to /dev/raw/raw10
    3. The root user executes ls -l /dev/raw/raw*, and found that /dev/raw/raw* are all root: root authority
    4. After communicating with the administrator, the customer accepts the temporary modification of the raw device authority. The modification command is as follows:
chown sybase:sybase /dev/raw/raw10
chown sybase:sybase /dev/raw/raw9
chown sybase:sybase /dev/raw/raw8
chown sybase:sybase /dev/raw/raw7
chown sybase:sybase /dev/raw/raw6
chown sybase:sybase /dev/raw/raw5
chown sybase:sybase /dev/raw/raw4
chown sybase:sybase /dev/raw/raw3
chown sybase:sybase /dev/raw/raw2

chmod 0660 /dev/raw/raw2
chmod 0660 /dev/raw/raw3
chmod 0660 /dev/raw/raw4
chmod 0660 /dev/raw/raw5
chmod 0660 /dev/raw/raw6
chmod 0660 /dev/raw/raw7
chmod 0660 /dev/raw/raw8
chmod 0660 /dev /raw/raw9
chmod 0660 /dev/raw/raw10
    5. Try to use the sybase user to start the sybase iq database again


    6. Log in to the tpaic library

    and the problem is solved!
