 103
 104 <p>Here's what I did</p>
 105
 106 <ul>
 107   <li>cd'ed into this snapshot view
 108 ~p6258c/p6258c_SIMCQ00000392_intview/vobs/simdev/bin</li>
 109
 110   <li>Checked out a script named east.</li>
 111
 112   <li>cd'ed out of the snapshot view to my home directory.</li>
 113 </ul>
 114
 115 <p>We now have a colocated snapshot view created on CC 6.0 and hosted by
 116 seast1. The storage (my home directory) oddly enough is served by
 117 cclinux...</p>
 118
 119 <ul>
 120   <li>Moved the view database over to cclinux under it's gdviews
 121 partition:
 122
 123 <div class=code><pre>
 124 <font color="#ff6600"><b>Cclinux:</b></font><u>mv /home/p6258c/p6258c_SIMCQ00000392_intview/.view.stg \</u>
 125 &gt; <u>/gdviews/p6258c/p6258c_SIMCQ00000392_intview.vws</u>
 126 </pre></div>
 127
 128   <b>Note:</b>
 129     <ul>
 130       <li>In the above command we also renamed .view.stg -&gt;
 131 &lt;viewname&gt;.vws.</li>
 132       <li>We did a mv instead of cp. I suspect that if you are in the
 133 snapshot view storage area and you perform a Clearcase operation,
 134 cleartool will notice the .view.stg directory at the snapshot view's
 135 root and not bother to attempt to contact the registry server to find
 136 out where the view database is. Instead it just says "Well the view
 137 database is right here". This would allow a disconnected, but colocated
 138 snapshot view to be able to perform Clearcase operations while
 139 disconnected.</li>
 140     </ul>
 141   </li>
 142
 143   <li>Reregistered the view:
 144

 151     <b>Note:</b>
 152
 153     <ul>
 154       <li>The -host changed from seast1 -&gt; cclinux</li>
 155
 156       <li>The -hpath changed to be relative to /gdviews (where we moved
 157 the .view.stg)</li>
 158   </ul>
 159
 160   <li>Retaged the view:</li>

 168     <b>Note:</b>
 169   <ul>
 170     <li>Again the -host changed from seast1 -&gt; cclinux</li>
 171     <li>The -gpath changed to a global path to /gdviews<br>
 172       <br>
 173     </li>
 174   </ul>
 175   <li>Stop the view server:</li>
 176
 177 <div class=code><pre>

 179 </pre></div>
 180   </li>
 181
 182   <li>Set the config spec to current since the compiled config spec
 183 still thinks it's on the old server. Note this will involve a ct update
 184 too. Also, we need to cd to the snapshot view storage area:</li>
 185
 186 <div class=code><pre>
 187 <font color="#ff6600"><b>Cclinux:</b></font><u>cd ~/p6258c_SIMCQ00000392_intview</u>
