T83-2015: Corruption of "registry.xml" file in versions 9.x of BIOVIA Pipeline Pilot Server

123

Resolution:
The following steps can be taken prior to release of and upgrade to Pipeline Pilot 2016 to address the issue:

If corruption of registry.xml occurs, the file can be repaired by running the command “DbUtil -t” from the command line. (The DbUtil utility is found in <server_install_dir>/bin on Windows and <server_install_dir>/linux_bin on Linux.)
To prevent future corruption of this file, the script <server_install_dir>/install/replacetokens.pl can be edited in two places to properly lock the file:

At the top of the file, add this line:

use Fcntl qw(:flock SEEK_END);

Replace the following block of code:

if (!open (OUT, ">$out")) {
logerror("can't write $out: $!\n");
return 1;
}
while (<TMPL>) {

with the following block that has four additional lines:

if (!open (OUT, ">$out")) {
logerror("can't write $out: $!\n");
return 1;
}
if (!flock(OUT, LOCK_EX)) {
logerror("can't lock $out: $!\n");
return 1;
}
while (<TMPL>) {
