when i checked the primary server tempdb space. Today morning again i restarted the sql server. By morning the disk got high space alert. So we increased the space in tempdb drive. Yesterday night we restarted the Secondary SQL Server ,then also the tempdb didnt became normal. I am not able to understand why secondary server tempdb is growing hugely. When we checked the Primary server the tempdb is fine.Not growing. A -primary(Synchronous),B-Secondary-(Async-Readable),C-Secondary(Asyn-Not readable).Fail over mode is Manual.įrom 2 days the secondary server tempdb is growing hugely. IndId 2 is the non-Clustered index and 1 is the clustered index (as i understand, because this table have only a non-clustered index and a clustered index). PS: this is the result of sp_locks when inserting a row: But till now, I can't ensure whether the deadlocks may appear or not. So, I have to submit a report about the solution describing how these locks work. The last version of the project met an unaccpetable frequency of deadlocks. All these statments now acquire locks in this order (as i understand, which may be misunderstanding): non-clustered index, then clustered index(table). But how do insert statments acquire locks? So I changed the statements and non-clustered indics, and the deadlocks SEEM to be disappeared.īut one thing is confusing me. The reason of most of the deadlocks is the orders of locking And they are locking, blocked and turning into deadlock very frequently. I got an unfinished project recently, which have serval sql statements executed very frequently. Rafael Cardoso de Araújo MCTS - SQL Server 2005 Someone please can help with some troubleshooting hint or even with an experience about this kind of problem. In sys.dm_os_memory_clerks we already faced more than 30GB of consumption I tried to find out what kind of class of token is present and the worse instance have only this entrys. We have around to 70 users in contained mode in this server and when the cache starts to grow it grow until starve the server for memory. This seems like a memory leak, because even running DBCC FREESYSTEMCACHE the objects are not released from memory. We are considering to use the trace flags 4621 as suggested by microsoft to avoid this memory pressure, but i want to know if someone has a tip to help me to understand thisīehavior. Run DBCC FREESYSTEMCACHE ('TokenAndPermUserStore') does not clear the cache. When this ocurr we have to do a failover and restart the principal node of AG. Anyway i'm facing this problem since the SQL Server 2016.Īt a certain moment this cache starts to grow at a rate of 6GB by day. We have an environment with some databases in contained mode executing in version SQL Server 2017. I'm experiencing a very weird problem with userstore_tokenperm clerk recently. Also 2017 certificate signature is 16 characters longer than from 2012. I have noticed that SQL server 2017 signature always starts with 0x01 but SQL server 2017 certificate signature starts with any hex characters. Is it somewhere described what has changed? I haven't found any documentation about it whatsoever. Or perhaps is it possible to somehow add the newer functionality to SQL server 2012 without upgrading to SQL server 2017? Is there any chance to enforce SQL server 2017 to use the old function to keep the compatibility? If I sign something on SQL server 2012, I can verify it on both 20 successfully, but if I sign it on 2017, I cannot verify it on 2012 (it is returning me 0 even though the correct certificate is used). That breaks verification of the string on SQL server 2012. Server 2012 even though I have used exactly the same certificate. However, with SQL server 2017, SignB圜ert is giving me different results than SignB圜ert in SQL We are using SIGNBYCERT and VerifySignedB圜ert functions to assure integrity of data. Recently I have upgraded one of our SQL server 2012 to SQL server 2017.
