A few days ago wrote a regular backup Sybase database script, in the shell after writing to try to manually execute, everything OK. The results are written to a cron timed file and are not executed at the time. Very puzzled, and checked a user, permissions, directory permissions, etc. (in fact, manual can carry out the instructions are all right), no problem ah, how is it going?
Then I saw an example of a predecessor and it dawned on me. Sybase's env
Linux is popular in a variety of operating systems. As a result, a growing number of mainstream database vendors are porting their products to Linux operating system platforms, such as Sybase, Oracle, and IBM. In addition, more and more free software can be used. The Free Software library already includes Sybase ASE for Linux, Oracle for Linux, Informix for Linux, database software, and many other software.
With the continuous popularization and application of database management system, enterprises require that important data of database will not cause data loss or data being unavailable because of the occurrence of various accidents. Correspondingly, the backup and recovery mechanism of database data shows its importance more and more. It is not difficult to imagine, finance, taxation, construction engineering all walks of life if there is no backup of the database, once the database corruption,
, ms SQL, and other inter-system data replication and synchronization.
Local autonomy: each node can determine what data it will accept and access and update the data of the current node.
How the replication server works
In this section, we will describe each part of the sybase replication server product and their functions. Data replication can be divided into four parts:

Recently, Sybase Central client (java client) was removed from IQ16.0. The new client may only use SCC ?!
For old users, it is undoubtedly a pain point.
It seems that only one client can be extracted from IQ15.4 or 15.3.
In this case, I wrote a command line client in the SDK library for indexing,
This is a very small and exquisite IQ command line client. It is interesting that it can also be used in ASA12 and later versions of the ASA database. This

The Sybase-Client (Java client) has recently been found removed from the IQ16.0. New clients may only use scc?!
For the old users, is undoubtedly a more painful thing.
It seems that only from IQ15.4 or 15.3 to pick a client out of use.
That being the case, I indexed a command line client with the SDK library.
This is a very small and exquisite IQ command line client, and interestingly, it can also be used in ASA12 and above versions of the ASA databa
