 Posted: Thu May 19, 2011 2:20 pm Post subject: Problems with temporary file names |
 |
|
I'm trying to resurrect a MySQL installation that went 'poof'* on an 8.4 Alpha, using the V5.1.46 kit from vmsmysql.org. Thanks to all the information there, I've managed to get mysqld up and running. Unfortunately, there's one issue that I haven't been able to fix.
MySQL regularly tries, and fails, to create temporary files with a '#' in the filename. A sample error message is:
| Code: | | MySQL error: 1; Can't create/write to file '/mysql051_root/mysql_server/tmp/#sql218048b3_55_0.MYI' (Errcode: 5) |
Files without the '#' are being created in MYSQL051_ROOT:[MYSQL_SERVER.TMP], so I'm looking at the '#' as the most likely culprit.
I've turned off binary logging for MySQL, as that seemed to cause issues with a '.~reg~' file (I wouldn't be surprised if these issues share a root cause...). I've also edited FIRST_RUN_MYSQLD.COM to use direct inserts into 'db' and 'user', instead of temporary tables. And I've modified the LIBZ_SHR[32|64] definitions in LOGICALS.COM to reflect our environment. As far as I'm aware, every other part of my installation is still at its default.
Has anyone every experienced a similar issue, or have any ideas on how to solve it?
Thanks in advance,
Daan

Sorry to ask a dumb question, but are you sure this Mysql kit comes from JFP ?
I remember that when he begun his work on porting Mysql on VMS, his very first work was to remove those # from the filenames of temporary files, as this is not possible in a VMS filename.
I know that some other people have too, ported Mysql to VMS, and there was the problem of the # character.
There is too, a possibility that JFP made a mistake, but could you double-check ?

Hello Daan,
Sorry, this was a change to fix another problem:
See note http://forum.vmspython.org/viewtopic.php?t=226
MySQL database should be on an ODS-5 disk.
If you have no ODS-5 disk you can create one using LD.
Regards,
Jean-François |

@bisonmalembouche: that was one of the first things I checked, so I hope it's not too dumb  . I'm not 100% sure how to verify that my kit is "Genuine JFP", but at least it seems to say "JFP" in all the right places.
@JFP: thanks for the reply. I'll see what a reinstall brings me.
Does anyone happen to know who maintains vmsmysql.org? I've tried registering there to add a hint about the ODS-5 requirement, but it won't let me...
Regards,
Daan |

I have disabled account creation on the wikis (vmspython and vmsmysql) due to spamer robots.
I can create an account for you if you want.

That would be nice.
After reinstalling to ODS-5, all filename related issues dissapeared. Thanks for the help!
By the way, I am experiencing the same issue that berryman reported here. It's not a showstopper for me, so I'm not creating a separate topic for it. But let me know if you'd like any information for testing purposes. |
