Lately, applying 12.0.1 EBFs on my box tends to leave me alone with that undesired
message. That has happened with both 126.96.36.19937 and 188.8.131.5254. In contrast to Karim's very helpful explanation that DLLs may be locked and can not be updated, whereas JAR files can, the situation seems just opposite here (at least currently):
Unfortunately, the latter one seems to get used by DBISQL and causes the error.
Note: I assured that neither DBSIQL nor SCView (nor their fast launchers) were running when the EBF was applied. There was no SQL Anywhere process running at all (and no other JDBC process, as far as I can tell), and I had restarted the box immediately before and after applying the EBF.
Well, I can copy the files from another box where EBF get applied without problems, but I would like to get to know what might cause this failing upgrade.
May this be due to the Java Quick Starter (jqs.exe) that was running by default? - That seems to be a program that might load often used JARs... - but I don't know whether it will preload some of the SQL Anyhwere jars and whether it will lock them.
Lately, I tried to install 184.108.40.20669 and made sure that
Still, after applying the EBF, the same bunch of JAR files was left unchanged. So apparently, they were not left unchanged because of being in use otherwise.
After that I checked the freshly generated setup log files, i.e. a SAInstall.log (with no clue) and a randomly named MSIzzzzz.LOG. The latter gave some clues:
Whereas for the correctly patched jodbc.jar file, the log was telling:
the problematic files had messages like the following one:
I don't know why they are treated as "modified" (other than I had copied them from another machine as stated in the question), but I then simply deleted them from the folder and re-applied the EBF.
That gave some "File xxx is missing" warnings, however those desired files have been copied now, with the MSIyyyy.LOG telling that
So in the end, I hope this strange problem is fixed (and I didn't have to uninstall and reinstall SA 12.0.1).
