Db2icrt creating an instance that indicates that the hostname is invalid

There is a phenomenon, after DB2 installation, using DB2ICRT to create an instance, the host name is not valid, prompting the following:

[Email protected] instance]#/db2icrt-u db2inst1 db2inst1

The host name "Centos-0.msdomain" is invalid. Specify a valid host name.

DBI1922N the host name is not valid.

Explanation:

The TCP/IP host name parameter is not a valid or does not exist.

User Response:

Ensure that TCP/IP is operational on the system. If a domain name server

is used, ensure the domain name server machine is active. Issue the

command again using the correct TCP/IP host name.

Dbi1079i Output is saved in the log file/tmp/db2icrt.log.2816.

Explanation:

All processed and failed operations has been saved into the this log file.

User Response:

Do not modify the this file on any. This file was for IBM Technical

Support Reference.

/opt/ibm/db2/v9.7/instance/db2iutil:line 2528:db2instver:parameter null or not set

Check the/opt/ibm/db2/v9.7/instance/db2iutil file (2528 lines not prompted) and find the following

${db2dir?} /instance/db2isrv-addfcm-i ${instname?} ${db2isrvopts?}

If [$?-eq 3]; Then

Db2isrv

${db2dir?} /instance/db2isrv-addfcm-i ${instname?} ${db2isrvopts?}

If [$?-eq 3]; Then

Display_msg ${db2cat?} 922 \

' dbi1922n the host name is not valid.\n ' <pre name= ' code ' class= ' Plain ' > Stop_prog 1</pre> fi<p& Gt;</p>

<pre></pre>

<br>

is when Db2isrv-addcfm-i ${instname?} ${db2isrvopts returns to 3 when the host name is not correct. <br>

This db2isrv found a lot of things, did not find specific content, look at the name is to add a service to the system. Behind is ADDFMC, the FMC is the DB2 fault daemon. <br>

This is to monitor the DB2 instance to run normally, and it will automatically launch the instance when the instance goes down unexpectedly. Then the above mistakes can be linked together:<br>

Adding a DB2 daemon to the system failed because the hostname was incorrect. <br>

Okay, take a look. Hostname definition <br>

<p></p>

<p></p><pre name= "code" class= "plain" >[[email protected] instance]# hostname

Centos-0.msdomain</pre>, that's fine. <br>

See <p></p> again

<p></p><pre name= "code" class= "plain" >[[email protected] instance]# vi/etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

:: 1 localhost localhost.localdomain localhost6 localhost6.localdomain6</pre><br>

This place does not know why CentOS has been installed after not modified, modified. Revised content as follows <br>

<p></p>

<p></p><pre name= "code" class= "plain" >[[email protected] instance]# vi/etc/hosts

127.0.0.1 localhost centos.msdomain localhost4 localhost4.localdomain4

:: 1 localhost localhost.localdomain localhost6 localhost6.localdomain6</pre><br>

Save again to create an instance, normal <p></p>
