We are unable to increase the quota on "Used transaction log file" to 32G of space. This is a quota limit set by H-sphere at 16 G. We set the corporate plan to all 32 G of space but this limit is set and database is stalled due to transaction log limit.
By default MSSQL quota divided between database file and transaction log file with ratio 50/50. If you need to change it you can do in Customer's CP.
MSSQL limits can be managed in Customer's Control panel in Databases->MSSQL DBs->Edit database settings->Change quota.
More details you can find here:
Please note: to see that ratio changing is applied you need to leave "edit database settings" page and then go into this page again.
