Dbcc trace on (3604, 317) – gives report about all the plans. To recover this we have to check out the number of servers running. Execute dbcc SQL TEXT (spid) : to view the details of the transaction. In this way, Adaptive Server does not have to recompile SQL statements for which it already has a plan.This allows the application to amortize the costs of query compilation across several executions of the same statement.The statement cache memory is taken from the procedure cache memory pool.

In this article, we have explained how to download and install Sybase IQ Server on Linux. Question2: Explain about the Sybase group? Parser checks for syntactical errors, compiler checks for query plan in the procedure cache, if not found it gets prepared by the optimizer, execute checks for data in data cache and if not found gets from the disk and sent back to user. If any one of them (data or query plan) is not found where expected, it’s called a MISS. ( Log Out /  A disk that is allocated to a server cannot be shared with other servers.

Stable Queue- after Replication Server is installed; a disk partition is set upused by Replication Server to establish stablequeue. .krg file will be automatically deleted when ASE server goes offline. When a process A is blocked by another process B, and B blocked by C, and continued in similar fashion till N number of processes, these all are blocked by the nth process. If the procedure cache is too small, a user trying to execute stored procedures or queries that fire triggers receives an error message and must resubmit the query.

Sybase for Linux may be one way to solve your problems. During the phases of execution, the single process can change to various states depending on the availability of the i/o, query plan, data, etc. If a query plan is available, it is placed on the MRU end of the chain, and execution begins.
