gLite DPM for MySQL known issues




httpd/mod_ssl update breaks GridSite

Tracked via Bug 65013

Description

Recently a RHEL4/SL4 update of httpd-2.0.52-41.sl4.7 and mod_ssl-2.0.52-41.sl4.7 was released to fix CVE-2009-3555. In this update the internal structures of mod_ssl were modified, causing gridsite-1.1.18 to fail.

For now the workaround is to keep the httpd-related rpms at their previous versions until bug #65013 is fixed.



Problem reported using glite-SE_dpm_mysql-3.1.33-0 and glite-yaim-core 4.0.8-7

Description


Some problems has been reported while using glite-SE_dpm_mysql-3.1.33-0 and glite-yaim-core 4.0.8-7. This can be solved updating to glite-SE_dpm_mysql-3.1.34-0 and glite-yaim-core-4.0.11-2.

Upgrading DPM database schema

Description


There is a potential problem while upgrading the DPM database schema, which is done as a part of the DPM 1.6.x to 1.7 upgrade. Sites with large mysql databases can run into an error when the schema update script is run, either manually or as a part of the YAIM configuration step. While no data should be lost because of the schema upgrade failure it will not be possible to subsequently run the DPM until the database schema is properly updated.

The problem is due to the default mysql InnoDB buffer pool size, which will not allow the schema change to be applied to a large database. A change can be made to the mysql server configuration to allow the update to succeed. However, if the update script has already been run an extra step is required to be able to successfully rerun the script.

Full details are documented here. It should also be noted that the upgrade take some time, possibly several hours.

In case there are any problems or questions after having checked the twiki please feel free to ask them in the direct support list (hep-service-dpm@cern.ch)

mod_ssl timeout error

Tracked via Bug 48458
