The MTP tim directory (/opt/CA/APM/tim) has been corrupted or has been accidentally deleted. This has also broken the MTP UI System Setup page and its Install Software option showing these respective errors:
Error assigning webrequestid. [Errno 2] No such file or directory
Web Request Id does not exits.
Error authenticating webRequestId 1
How can we recover from this when the Install Software option is unusable for a tim reinstall?
The primary cause of the errors is the missing tim binary /opt/CA/APM/tim/system/bin/webrequestid
Release: CEMUGD00200-9.7-Introscope to CA Application-Performance Management-Upgrade Main
The tim can be re-installed directly on the MTP server without going through the UI. The required steps are:
1. cd /usr/local/wily/tim-mtp/files
If the tim rpm package file exists e.g. tim-10.1.0.20.990300-0.Linux.el6.x86_64.rpm, reinstall it using this rpm command:
rpm -i --force tim-10.1.0.20.990300-0.Linux.el6.x86_64.rpm
That should resolve the MTP UI errors after refreshing the System Setup page
2. If the tim rpm package file does not exist follow these extra steps:
Run script ./install
The following error may occur:
ln: creating symbolic link `/etc/wily/tim-mtp/tim-mtp': File exists
** Error: cannot link /usr/local/wily/tim-mtp to /etc/wily/tim-mtp
To resolve remove the symbolic link /etc/wily/tim-mtp i.e. run "rm /etc/wily/tim-mtp"
Re-run script ./install
After the prerequisite checks are PASSED this message may appear after the script completes:
"package tim-10.1.0.20.990300-0.x86_64 is already installed"
The tim rpm package file should now be present in /usr/local/wily/tim-mtp/files so follow the steps in #1 above.
