|

|
<p>Use the command STRHOSTSVR SERVER(*ALL) to start them if necessary.</p>
|

|
|
<ul><li>Verify QZDASRVSD, the ODBC socket daemon, is running in the QSERVER subsystem. <ul><li>as-database should be in the Listen State</li>
|

|
|
<li>WRKJOB QZDASRVSD should be used to check the job log of the daemon for

any error messages.</li>
|

</ul>
|

</li>
|

<li>Verify that socket daemon QZSOSMAPD is running in QSYSWRK subsystem. <ul><li>as-svrmap should be in the Listen State as shown by NETSTAT *CNN.</li>
|
||

|
<li>WRKJOB QZSOSMAPD should be used to check the job log of the daemon for

any error messages.</li>

<p>The PC locates the socket used by the database server by connecting to
|
||
|
|
the server mapper socket. It retrieves the socket used by as-database. It
|
||
|
|
then connects to the proper socket which is being monitored by the database
|
||
|
|
server daemon, QZDASRVSD. The server daemon will attach the client's connection
|
||
|
|
to a QZDASOINIT prestart job in QUSRWRK. If this is the first connection made
|
||
|
|
to the server from this PC, then two other servers are used: Central server
|
||
|
|
for licensing and signon server for userid/password validation.</p>
