After you download ase15.0.2 from the Sybase official website, if you select to install express edition or Developer Edition, you will not encounter any problems, except for some limited functions.
However, most of them may be Enterprise Edition for evaluation, that is, Enterprise Edition trial. This problem occurs when the license expires one month later and the server cannot be started. As a result, it is very depressing. Most people may choose to uninstall and reinstall it. Of course, this is okay, but it is a waste of time.
For a while, I thought I could only solve it like this.
Actually not. After talking with experienced people on the Sybase forum, we found that the switch was possible.
First, there are three installation types:
1. Express edition, free of charge.
2. Developer Edition, which is used for development and testing without restrictions on service life. It seems that it cannot be commercialized. It doesn't matter. I just learned that. In the past, there was a 60-day limit.
3. Enterprise Edition, which has a trial time limit. It is 30 days.
You only need to find the switch.
Your solution is to switch the license of the enterprise edition to the development or express edition. How to cut it?
First look at the three files under the $ Sybase/SYSAM-2_0/licenses directory:
Sybase_ase_de.lic sybase_ase_xe.lic
The first file contains the following content:
Pe = de; Lt = dt
The second file contains the following content:
Pe = Xe; Lt = CP
In the $ Sybase/$ sybase_ase/sysam/
Pe = EE
Lt = eV (or et) or something
Replace the values behind PE and LT with the values in the preceding two files.
Replace:
Pe = XE
Lt = CP
It becomes the Express version.
Replace:
Pe = de
Lt = dt
It becomes a development version.
So, you can use it normally, at least there is no deadline limit.
The other way around, that is, you started to use the development version. Later, you bought a valid license. After installing the license file, find the PE and Lt values, then modify $ Sybase/$ sybase_ase/sysam/
Of course, there is another way to avoid license switching, that is, to find a new machine or install a virtual machine with the same operating system on your own machine, and reinstall a Sybase ASE, find
