shell - Export blob data from Oracle -


i have requirement need read customer_file file contains unique customer ids shell script , export corresponding blob data oracle db table of each customer file. exported blob data files again loaded different database.

i have used java read file, connect database , export blob data file.

this solution works fine when number of customer ids 0-100. leads performance issues when have large number of customer ids (say 10000). create 10000 files in server.

is there solution combine blob data files single file , later split , use it.

or other solution?

if you're using java, write each blob/file tar/zip archive, result being 1 tar/zip archive containing blobs. of course, when come extrac, if extracting problem, can restrict extract particular file(s).

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
